Westlie, Mariah J. The Correlation between Childhood Obesity and Socioeconomic Status

Abstract

As a state dedicated to the health of its children and adolescents, the South Dakota

Department of Health 2020 Plan contains an objective of childhood obesity being equal to or less

than 14% (Biskeborn, Buhler, Cushing, Gildemaster, & Christensen, 2012). However, according to a

recent National Health and Nutrition Examination Survey (NHANES), 31.9% of U.S. children

between the ages of 2 and 19 are overweight or obese (Williamson et al., 2009). The objective of

this study was to determine if any relationship existed between childhood obesity and a low

socioeconomic status. Anthropometric measurements of school-aged children as well as National

School Lunch Program enrollment data were obtained from the South Dakota Department of Health

in the spring of 2012. A variety of statistical analyses were performed. From the correlational

analysis, a moderate positive relationship was found (r= +.385, p<.05, Pearson Correlation) between

childhood weight status and enrollment in the national school lunch program. Results indicated that

childhood obesity is a problem in both genders and many different ethnicities in the state of South

Dakota. From these results we conclude that a low socioeconomic status may influence the weight

of a child. This is most likely due to many internal and external factors.

Chapter I: Introduction

Statement of the Problem

Childhood obesity is a significant health problem that has been growing exponentially in

the United States in recent years, and current studies have concluded that there is a strong

correlation between childhood obesity and low socioeconomic status. As a state dedicated to

the health of its public including children and adolescents, the South Dakota Department of

Health 2020 objective of childhood obesity should be about equal to or less than 14%. In 2010

the percentage of obesity in children was 15.2% (Biskeborn, Buhler, Cushing, Gildemaster, &

Christensen, 2012). According to a recent National Health and Nutrition Examination Survey

(NHANES), 31.9% of U.S. children between the ages of 2 and 19 are overweight or obese, and

often children who are overweight or obese at a young age will reach adulthood at an

unhealthy weight (Williamson, Champagne, Han, Harsha, Corby, Newton, 2009). This epidemic

is not only affecting the United States but other developed countries as well including the

Middle East, Central Europe, and Eastern Europe. For example, Saudi Arabia and Iran are

among the top seven countries with the highest prevalence of childhood obesity with 16% of

their population of adolescent girls having BMI rankings in the 85th-95th percentile, a number

comparable to the 16.8% of adolescent girls in the United States (Pourhassan & Najafabadi,

2009). Globally, since 2010 the number of overweight children (under the age of five) has

grown to an estimated 43 million, while 35 million of these children live in developed countries

(World Health Organization, 2011). With this trend continuing in recent years, it is likely that

obesity in children will continue to grow exponentially.

Childhood obesity is considered a serious medical condition that occurs when a child is

above the normal body mass index for his/her weight and age (Mayo Clinic Staff, 2012a).

Childhood obesity is not only detrimental to the child’s health but it can also lead to abnormal

growth and maturation. If a child is overweight or obese, they are at a significant risk of

developing more serious health conditions including type 2 diabetes, heart disease,

hypertension, and even musculoskeletal disorders (Babey, Hastert, Wolstein, & Diamant, 2010).

A low socioeconomic status within families may correlate with childhood obesity. According to

the American Journal of Public Health, “Cross-sectional data have shown an inverse relationship

between family income and obesity prevalence among children and adolescents, although

some studies suggest that relationship differs according to race/ethnicity and gender” (Babey et

al., 2010, p.2507). This contributing factor of a low income can have a negative effect on both

the child’s diet and nutrition knowledge which can lead to overweight and obesity at an early

age. Family and school life both play a major role; if children are raised in poverty, they are less

likely to have access to healthy food, less likely to have the knowledge of good nutrition, have

an increasingly sedentary lifestyle, and also have less influence from their parents on healthy,

home-cooked meals.

Even in the last few years while rates of childhood obesity has increased, the magnitude

of income disparity in the U.S. population continued to rise as well. In 2001, the prevalence of

obesity was 70% higher in adolescents whose family incomes were below the federal poverty

line than those whose incomes were 300% above the poverty level (Babey et al., 2010). Poverty

is an especially important factor to consider when dealing with childhood obesity because there

are many risk factors that are associated with poverty that can have a strong negative influence

Page 10: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

10

on a child’s well-being and health. Risk factors that stem from poverty and a low socioeconomic

status include (but are not limited to) instability, poor housing quality, family turmoil,

inadequate meal times, nutritionally low and calorie dense foods, lack of education, poor sleep

habits, and sedentary activity (Wells et al., 2010). However, the extent and time to which a

child remains at poverty level may influence their weight and health not only as a child but also

into adulthood.

Low socioeconomic status and poverty are not only risk factors for childhood obesity

but for adult obesity as well. In recent findings, it has been found that children who grew up

overweight or obese at a low socioeconomic status are more likely to create bad nutrition

habits and lack proper nutrition knowledge when they are older, which in turn exacerbates

their health problems and makes potentially life threatening and chronic conditions. In order to

demonstrate the claim that childhood socioeconomic status influences adulthood health and

BMI, a recent study published data supporting this theory. According to the American Journal of

Public Health, as childhood socioeconomic status decreased the body mass index as well as

waist-to-hip ratio increased significantly at age 26 years in both men and women. The article

continued further by stating 80% of women who grew up within a low socioeconomic

household were overweight or obese at adulthood compared to that of 40% from a higher

childhood socioeconomic status (Wells, Evans, Beavis, & Ong, 2010).

The health and well-being of a child is strongly influenced by the socioeconomic status

to which they were raised in, and in order to intervene on this growing epidemic, these

problems need to be addressed. Although a low socioeconomic status may prove to be a

disadvantage, parents/guardians should still be able to have access to the proper tools,

Page 11: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

11

resources, and knowledge in their community for their children to be raised in a healthy home

environment. It is always important when intervening on childhood obesity to make sure that

intervention strategies are always culturally appropriate as well as appropriate for the current

socioeconomic conditions of the target population (Pourhassan & Najafabadi, 2009).

Purpose of the Study

The purpose of this study was to determine whether or not poverty is correlated to

childhood obesity and BMI index of children located within the state of South Dakota. Data was

obtained from the South Dakota Department of Health during the spring of 2012; this data was

then correlated with participation in the National School Lunch Program from the school year

2010/2011.

Research Objectives

This study will attempt to determine if a correlation exists between:

Childhood obesity and low socioeconomic status.

This study will attempt to determine if there is a change:

In the occurrence of overweight and obese children in South Dakota between the years

2010 and 2011.

Definition of Terms

The following terms are defined in order to receive a clear understanding of this study.

Body Mass Index: Abbreviated as BMI, body mass index is defined as a measure of

body weight relative to height. The ratio of the weight of the body in kilograms to the

square of height in meters (BMI = (weight in kg)/ [height (m)]2) (Centers for Disease Control

and Prevention, 2011b)

Page 12: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

12

Healthy weight: For children, a healthy weight is a weight that is between the 5th and

85th percentile for the correct age and gender. (Centers for Disease Control and Prevention,

2011b 11).

High Risk Group: Comprises children and adolescents with a body mass index above the

85th percentile based on corresponding age and gender (Viewegg, Johnston, Lanier,

Fernandez, & Pandurangi, 2007). Thus, for children, those who are classified as overweight

or obese are in the high risk group.

Obese: In children, obesity is defined as a BMI that is equal to or greater than the 95th

percentile for age and gender (Centers for Disease Control and Prevention, 2011b).

Overweight: In children, overweight is defined as a BMI that is between the 85th and

95th percentile for age and gender (Centers for Disease Control and Prevention, 2011b).

Socioeconomic Status: Is defined and conceptualized as social standing or class of an

individual or group, this is measured as a combination of education, income, and occupation

(APA, 2011).

Assumptions and Limitations

In this study, it is assumed that anthropometric collecting techniques that were used for

measuring the children were made both with reliability and validity.

There are a few potential limitations to this study. Limitations of this study include the

variety sample population of this study. The population of South Dakota is unique due to the

fact that there are more Native Americans present in the population than many other states;

thus generalizing this data to all states across the United States could result in a skewed

perception of data.

Chapter II: Literature Review

The following chapter will begin with a synopsis of childhood obesity including

definition, risk factors, occurrences, and health detriments. It will further continue to overview

the occurrences of childhood obesity from those with poor socioeconomic status, and why this

might occur.

Definition

Obesity in adults is defined as a body mass index (BMI) of 30 or higher. BMI in adults is

often used as the determining factor when it comes to a set weight versus height ratio because

it correlates to a person’s total amount of body fat (Centers for Disease Control and Prevention,

2012). However, in children, BMI is age and gender specific, and is commonly referred to as

“BMI-for-age”. For children, BMI is plotted upon the CDC BMI-for-age growth chart (according

to gender) in order to obtain a percentile ranking, this percentile indicates the child’s BMI

relative to children of the same gender and age(Appendix E) (Centers for Disease Control and

Prevention, 2011b). Currently, “BMI-for-age” remains as the most common measure to use in

assessing a child’s weight status because it is inexpensive and non-invasive when compared to

other body fat measures (Centers for Disease Control and Prevention, 2011b). The rankings for

weight status are as follows: underweight is below the 5th percentile, healthy weight is

between the 5th and 85th percentile, overweight is between 85th and 95th percentile, and

obesity is equal to or greater than the 95th percentile (Centers for Disease Control and

Prevention, 2011b). If a child is in the overweight or obese category (higher than the 85th

percentile), medical professionals define them as “high risk” (Vieweg et al., 2007).

Occurrence

Childhood obesity has become one of the fastest growing epidemics in many developed

countries, and a recent estimate has found that around 17.6% of children in the United States

are obese, and that 70% of obese children will grow into obese adults (Pourhassan &

Najafabadi, 2009). The prevalence of obesity in children in developed countries has continued

to rise steadily since 1971 (with variability in some countries), and the highest prevalence of

childhood obesity remains in regions of the world such as North America, the Middle East,

Central Europe, and Eastern Europe (Pourhassan & Najafabadi, 2009). In the United states,

results from the National Health and Nutrition Examination Survey (NHANES) showed that

among pre-school age children (aged 2-5) rates of obesity more than doubled from 5% to 10.4%

between 1976-1980 and 2007-2008 (Centers for Disease Control and Prevention 2011a). These

rates of obesity also increased from 6.5% to 19.6% in 6-11 year olds, and 5% to 18.1% in 12-19

year olds, during the same time period (Centers for Disease Control and Prevention 2011a).

These staggering statistics are still continuing to grow and it has many medical professionals

fearing the worst for our future generations. Adolescents who are obese, or who are at high

risk for becoming obese are more likely to become obese as adults. According to the Center of

Disease Control, “…approximately 80% of children who were overweight at aged 10–15 years

were obese adults at age 25 years...and if overweight begins before 8 years of age, obesity in

adulthood is likely to be more severe” (Centers for Disease Control and Prevention 2011a, p.1).

The National Health Examination Survey (NHES) and the National Health and Nutrition

Examination Survey (NHANES) support this claim on childhood obesity because it is apparent

from the data in past and recent surveys that the obesity has nearly tripled in the past 50 years

Page 15: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

15

(Centers for Disease Control and Prevention, 2012). In a past NHANES surveys from 2003-2004

and 2005-2006, there showed no significant changes on the prevalence of obesity in children

and adolescents; however, the current NHANES reports from 2010-2011 show that nearly

18.7% of children aged from 6-19 years old were obese a significant increase from 2003. Lastly,

the most current the data from the NHANES reports shows that 19.6% of children aged 6-11,

and 18.1% of individuals 12-19 years old were considered obese (Biskeborn, et al., 2012). Obese

children are at a much greater risk than their normal weight counterparts for many health

problems during their youth and adulthood if the weight problem is never resolved.

Risk Factors

Risk factors for childhood obesity are often varied and can be attributed to many

different internal and external factors in the child’s life. One of the major risk factors that make

a child susceptible to becoming overweight or obese is diet. A diet high in fat, high in refined

carbohydrates, and low in fruits, vegetables, and fiber can work in combination with other risk

factors to increase the vulnerability of becoming overweight or obese (Mayo Clinic Staff,

2012d). Several other risk factors include lack of exercise, family history and environment,

psychological state, and socioeconomics (Mayo Clinic Staff, 2012d).

The United States has rapidly become a more technologically diverse nation, and with

new technology often times exercise and physical activity is forgotten by the wayside. In recent

years, children have experienced a significant decrease in their physical activity and exercise,

while sedentary behaviors including TV watching and computer gaming have increased (Bellows

& Roach, 2010). Children between the ages of 8 and 18 are averaging 3 hours per day involved

with technology-related sedentary activities including television, video games, DVDS, and

Page 16: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

16

movies (Bellows & Roach, 2010). Thus, extracurricular activities such as sports and outside play

time are becoming minimal in many children’s lives. The Colorado State University Extension

further explains the negative impact of technology-related sedentary activities on the increased

occurrence of childhood obesity,

Several studies have found a positive association between time spent watching

television and prevalence of overweight in children. Sedentary behavior, and specifically

television viewing, may replace time children spend in physical activities, contribute to

increased calorie consumption through excessive snacking and eating meals in front of

the television, influence children to choose high-calorie, low-nutrient foods through

exposure to food advertisements, and decrease children’s metabolic rate (Bellows &

Roach, 2010, p.1).

Family life also has a large impact on a child’s health and weight status because

overweight or obese children often come from an overweight or obese household (Mayo Clinic

Staff, 2012d). It is more likely when children have this background that they be more

susceptible to gain excess weight due to an environment with calorie dense foods and low

physical activity (Mayo Clinic Staff, 2012d). Children are not always capable of procuring and

making their own meals, and if the parents/guardians are supplying the household with calorie

dense foods, then that is what the child will eat. Behaviors such as these in family households

can contribute to weight gain in children as well as the entire family (Mayo Clinic Staff, 2012d).

Another major risk factor involved in a child’s weight is psychological state, some

children, like adults, will use food as a cure to their problems; other children may eat because

Page 17: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

17

of boredom, stress, or high running emotions. Often, these behaviors are similar in the child’s

parents or guardians (Mayo Clinic Staff, 2012d).

Finally, and the focus of this thesis, is that socioeconomic status contributes to a child’s

weight. Low socioeconomic status, in itself may influence a variety of factors than can

contribute to an overweight child. Data published in the Southern Medical Journal elaborates

on these potential factors that may affect the occurrence of overweight and obese with

socioeconomic status, factors including:

…health insurance; neighborhood and personal safety; local schools and their resources;

local food stores and the extent to which they carry health foods; the price of food;

private and public transportation; proclivity to watch television and participate in other

sedentary activities; subsidized local, state, and federal programs; and access to gyms

and health clubs. (Vieweg et al., 2007, p.11).

In this same study, over a 7 year period, BMI percentile in children (with a beginning average

age of 8.8 years) increased significantly due to socioeconomic status. As an entire group, the

overweight prevalence increased from 31% to 40%, but when analyzing the status of children

with low socioeconomic status, overweight prevalence jumped from 37% to 67%, which

suggests a strong correlation between weight status and socioeconomic status (Vieweg et al.,

2007). The CDC also stated, “One of 7 low-income, preschool-aged children is obese… the

prevalence of obesity in low-income two to four year-olds increased from 12.4% in 1998 to

14.5% in 2003” (CDC, 2011a, p.1). Socioeconomic status along with other serious risk factors

can be major determinants to whether or not a child may become overweight or obese at a

young age.

Health Detriment

Obese and overweight children are starting to experience health consequences at an

earlier age than those in any other decade, and have to deal with conditions, that until now

were only affecting adults. Childhood obesity is a condition that can have severe consequences

on a child both physically and mentally. Physically, obese children are at an increased risk for

many diseases including cardiovascular disease, which encompasses high cholesterol levels,

high blood pressure, and abnormal glucose intolerance (Centers for Disease Control and

Prevention, 2011b). In a random, population-based sample of 5-17 year old children, 70% of

obese children were suffering from at least one cardiovascular disease symptom, while 39% of

obese children suffered from 2 or more (Centers for Disease Control and Prevention, 2011b).

Other health risks that may occur as a result from childhood obesity include: asthma, fatty liver,

sleep apnea, and type 2 diabetes mellitus (Centers for Disease Control and Prevention, 2011b).

Health complications that stem from childhood obesity are often associated with a shorter life

span and can greatly affect the outcome of a child’s life (Choudary, Donnelly, Racadio, & Strife,

2007).

In order to increase life expectancy of children and improve their quality of life and

health conditions, it is of increasing importance to slow and prevent the epidemic of childhood

obesity that arise from potential risk factors such as socioeconomic status. Overweight and

obese children not only will have a poor quality of life at a younger age, but will also experience

these ailments and diseases into prolonged life.

Chapter III: Methodology

Introduction

Data in this thesis was collected previously; the following chapter includes an overview

of the methods and data collection techniques that were used by the South Dakota Department

of Health completed in the school year 2010/2011. Before data analysis was started, approval

was necessary from the UW-Stout Institutional Review Board (IRB). The chapter will also include

methods of data analysis, correlational tests of significance that were performed, and finally

the limitations to the study’s methodology.

Data from the South Dakota Department of Health

The existing data that was received from the South Dakota Department of Health for

analysis in this thesis included both public and private schools located within South Dakota

(Appendix B). All data was received anonymously. The sample population that was analyzed is

school aged children, grades 1-5 (ages 5-11), both male and female, the majority Caucasian.

Data that was used in this study were the anthropometric measurements of the children, this

was assumed to be collected using methods, techniques, and tools that were pre-approved and

overseen by a medical professional (i.e.: school nurse). The sample form used for data

collection can be found in the Appendix A. Measures taken on the children included weight,

and height.

Data obtainment took place in spring 2012. The intention of data obtainment was to

first receive permission from The South Dakota Department of Health to analyze their

preexisting data, including both anthropometric measurements of their children as well as their

National School Lunch Program participation. The data set for 2010-2011 academic year from

Page 20: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

20

the South Dakota Department of Health included over 49,000 students. The data set for the

2009/2010 academic year included over 40,000 students. The data from each student collected

by the South Dakota Department of Health included school name, county, education region,

date of birth, height, weight, gender, and ethnicity. From the National School Lunch Program

data set, the data that was collected by the DOH included school district, school name, site

enrollment, and percent of students eligible for free and reduced priced meals. The South

Dakota Department of Health followed specific guidelines for data collection (Appendix A). The

following text summarizes the data collection methods utilized by the South Dakota

Department of Health:

The Coordinated School Health Program sent letters to all South Dakota school health

and physical education teachers and school nurses requesting that schools share their

height and weight data with the DOH. Copies of this letter were also sent electronically

to superintendents and building principals. Data collection instructions on the correct

way to measure children and forms to submit data were posted on the project

website...School participation in the data collection effort is voluntary and there is no

payment for submitting data. South Dakota completed this project for the thirteenth

time during the 2010-2011 school year (Biskeborn, et al, 2011).

Data from National School Lunch Program

“In South Dakota, the Child and Adult Nutrition Services is responsible for administering

the U.S. Department of Agriculture’s Food and Nutrition Services and Food Distribution Division

Programs” (Biskeborn, et al, 2011). The programs that this department is responsible for

includes: summer food service, child and adult care food, team nutrition activities, commodity

supplemental food program, USDA food distribution for child nutrition programs, the

emergency food assistance program, fresh fruit and vegetable program, special milk,

reauthorization, and lastly the National School Lunch and School breakfast program (Biskeborn,

et al, 2011).The National School Lunch Program (NSLP) is a federally assisted meal program that

is able to operate both within public and non-profit private schools as well as licensed and

accredited residential child care institutions (Biskeborn, et al, 2011). The National School Lunch

Program provides nutritionally balanced, low-cost or free lunches to children each school day,

however, in order to determine eligibility for low-cost or free lunches; specific requirements

must be met (such as income). The data that was received from the South Dakota DOH on the

NSLP enrollment was able to provide a resource for an estimate of socioeconomic status for

students enrolled in both public and private institutions. The percent of students enrolled in the

NSLP was based on percent enrolled by region. In order to properly assess the children’s

socioeconomic status, the preexisting data from the DOH was analyzed from the school’s 2010

enrollment of the National School Lunch Program. Participation within this program indicated

the student’s socioeconomic status, and provided a correlation for the anthropometric

measurements of the children.

Data Analysis

Once the data from the DOH and NSLP had been received it was then compiled together

into a larger data base in order to ensure proper organization and data analysis. From the given

height and weight of the students, BMI was then calculated using the appropriate equation

placed into an Excel spreadsheet. This metric equation that was used to calculate the BMI of

the children was (weight (kg)/ [height(m)]2 (CDC, 2009a), this value was then plotted on the

22

Center for Disease Control and Prevention (CDC) BMI-for-age and gender charts to determine

the percentile of each child (Appendix E). Each child was classified into one of four categories

based on the percentile determined (Table 1). For further analysis on the National School Lunch

Program data, the schools were broken down into corresponding education regions and

correlated with the occurrence of overweight and obesity. Analyses and statistics were run on

both the anthropometric measurements of the children and the National School Lunch Program

enrollment; this included descriptive statistics as well as a Pearson’s r correlational test for

significance. The program used for statistical analysis was the Statistical Program for Social

Sciences (SPSS), version 17.0. Error bars on graphs represent the SEM.

Table 1: Classification of Weight Status Based on Percentile Ranking Weight Status Percentile

Normal Weight 5th≤85th percentile

Overweight 85th<95th percentile

Obese ≥95th percentile

Limitations

The major limitation in this study was the diversity of the participants—the majority

population of South Dakota is Caucasian with a large minority of Native Americans (~10%) and

because obesity and poverty seem to be closely related with race and ethnicity, generalizing

this data to all populations across the United States may result in a skewed perception of data

(if the population is largely different). The preexisting data that was taken from the South

Dakota Department of Health also included limitations that might affect the data analysis:

Data quality has been determined to be within acceptable standard deviation but has

the following limitations: First, schools voluntarily submitted height and weight data

Page 23: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

23

from across the state, but no attempt was made to obtain a representative sample.

However, school personnel collected data for 35.2 percent of the state’s students from

193 schools. While American Indian students comprise 15.8 percent of the South Dakota

enrollment population, they represent 10.1 percent of the students surveyed. Second,

the data was filtered and the following types of records were removed: data that had

biologically implausible results, entries where all essential data elements were not

completed, and duplicate records. After removing the above cases, the sample size was

49,146 students and 193 schools for analysis. Third, while the instructions included the

type of equipment and technique that schools should use, there is no assurance that

school personnel always followed the instructions. The DOH provided balance-beam

scales and wall-mounted measuring boards to schools to help improve the quality of

data. While it is not known what training persons who obtained the measurements had,

it is known that school nurses or school health and physical education teachers obtained

or supervised the data collected. Fourth, South Dakota’s height data are of acceptable

quality, however, worldwide measurements of height tend to be of marginal quality.

There could be several possible reasons for this including the use of measuring

equipment that did not allow accurate heights to be obtained. This can occur when the

person doing the measuring is shorter than the person being measured. Those who

measure adolescents may need to stand on a step stool or a chair to have their eye level

above the child’s head. In addition, if the measuring stick on a standing scale was used,

the children would be inaccurately reported as shorter than they are. South Dakota

should be aware of this problem when determining heights. This may be solved now as

24

adolescent height is more normal but this may explain the high level of short stature for

the 1998-1999 school year (Biskeborn, et al, 2011).

Chapter IV: Results

This chapter will include results based on gender, ethnicity, age, and school location and

a detailed analysis of the National School Lunch Program that has been correlated with the

2010-2011 South Dakota public school anthropometric measurements.

Demographic Data

49,791 students were surveyed and measured within the South Dakota public and

private school system for their anthropometric measurements. Of the students measured, 79%

were White non-Hispanic, 10% were American Indian/ Alaska Native, 3% were Hispanic, 3%

were Black non-Hispanic, 2% were ‘other’, 1% were Asian, 1% were Hawaiian/Pacific Islander,

and 1% were ‘not specified’ (Figure 1). Within the large population of these students there

were differences found between the student’s BMI and their ethnicity/race (Figure 2). The

average BMI among the different races of the students ranged from 18.4-21.1 with a standard

26

margin of error at .238. The highest average BMI belonging to the Black Non-Hispanic sample

population with an average of 21.1 (+/-.12); Hawaiian/Pacific Islanders with an average of 20.7

(+/-.37); Hispanic with an average of 20.5 (+/-.18); ‘other’ with an average of 19.4 (+/-.56);

White non-Hispanic with an average of 19.4 (+/-.15); American Indian/Alaskan Native with an

average of 19.1(+/-.11); Asian with an average of 18.9 (+/-.23); and lastly ‘not specified’ with an

average of 18.4 (+/-.19)(Figure 2). A one-way ANOVA was used to determine the significance of

this data, and from this test it was found that the differences between groups was found

significant with a p-value =.042 (p<.05).

Table 2 indicates that the most frequent occurrence of overweight (85th≤95th

percentile), in accordance to race, was found within the American Indian/Alaska Native

category, followed by ‘not specified’, ‘other’, and White non-Hispanic with 19.4%, 17.1%,

16.8%, & 15.5% respectively (Table 2).

Similarly, the most frequent occurrence of obese children (>95th percentile) was also

found within the American Indian/Alaska Native population with a 26.9% occurrence, followed

by ‘not specified’, ‘other’, and White non-Hispanic with 20.5%, 18.7%, and 13.2%, respectively.

With a combined total of overweight and obese children in the categories of White non-

Hispanic, American Indian/Alaska Native, ‘other’, and ‘not specified’ (not taking the other

ethnic groups into consideration) the occurrence of overweight and obese children surveyed

within this South Dakota population exceeds 30%.

Gender Data

Next, in respect to gender, the sample population consisted of 48% males and 52%

females, and within these two groups, differences were also found among the South Dakota

students. These differences showed the frequency of overweight and obese in both genders as

well as a variety of ages. Table 3, summarizes the amount of overweight and obese body mass

index by gender (utilizing data from 2009/2010 and then comparing it to that of 2010/2011) in

both female and male participants. From 2010 to 2011, the female’s overweight and obese

body mass index decreased from 16.7% and 16.0% to 16.1% and 15.2%, respectively; the male’s

Page 28: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

Age Data

Table 4 illustrates data found from anthropometric measurements regarding BMI-for-

age statistics for South Dakota students. The data shows age groups 5-8 and 9-11, as that is

defined as ‘childhood’. This table indicates that both of these age groups in South Dakota have

a larger occurrence of overweight and obesity than what is desired from the South Dakota

Department of Health (≤14%). The percent of obese children aged 5-8 years in 2010 was 13.0%

Page 29: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

29

and the percent of obese children aged 9-11 years was 16.3%; with a total combined value of

14.5% (Table 4). Figure 3 illustrates a more visual representation of Table 4 for the occurrence

of overweight and obese students organized by age. It is important to note an overall

increasing trend in the occurrence of overweight and obese students as they progress in age.

In reference to Appendix D, South Dakota is divided into 6 different geographical regions

which have been numbered 1, 2, 3, 5, 6, & 7(there is no region 4). Table 5 shows the highest

combined occurrence of overweight and obese in region 5 at 40.0% followed by region 6 at

37.1%, region 1 at 33.3%, region 7 at 29.4%, region 2 at 27.7%, and lastly region 3 at 21.0%.

National School Lunch Program Data

Table 6 illustrates the percent of students eligible for free and reduced priced meals by

region. The results showed that the percent eligible for free and reduced meals for all regions is

at an average of around 37.97%, which is more than 1/3 of all students in South Dakota that

received free or reduced cost meals in 2010-2011 school year. The region in which the most

6, region 7, region 2, and finally region 1.The range between the highest participation region (5)

and the lowest participation region (1) was nearly two fold.

Figure 4 is one of the most important figures to this research, as it correlates the

National School Lunch Program enrollment by region in South Dakota with that region’s specific

overweight and obese combined occurrences. After running a Pearson’s Correlation test

between these two variables the Pearson’s r-value is +.385 at a confidence level of .05,

indicating a moderate positive correlation. As the percent of students who are eligible for free

and reduced priced meals increases so does the occurrence of overweight and obesity of South

Dakota students.

Chapter V: Conclusions and Discussions

This chapter will begin with the conclusions made from the results; then followed by a

discussion comparing and contrasting the results, and lastly it will end with recommendations

for the future.

Conclusions

It was found that Native Americans, around 10% of the sample population in South

Dakota, showed a more frequent occurrence of being overweight or obese, in comparison to

the other races. In respect to gender, significant differences were found among the South

Dakota participants; males in the population had a higher occurrence of obesity when

compared to females, and in comparison from previous data collected in 2009/2010 by the

South Dakota Department of Health, the occurrence of overweight and obese in both male and

female students decreased in 2010/2011. According to the data analyzed, both age groups of 5-

8 and 9-11 in South Dakota have an issue with the occurrence of overweight and obesity with a

higher combined total occurrence than the South Dakota’s healthy kids 2020 objective of ≤14%.

The results for body mass index by regions of South Dakota show that the highest combined

occurrence of overweight and obesity was found in region 5, followed by region 3, region 6,

region 1, region 7, and lastly region 2. It should be noted that region 2 was the only region that

was considered significantly below the state’s confidence interval rate of 14.9% while regions 3,

5, and 6 were significantly higher than the state rate. Lastly, the data analysis on the National

School Lunch Program showed that more than 1/3 of all students surveyed were eligible for

free and reduced meals, which was a similar figure for the occurrence of overweight and obese

children. The region in which the most students are receiving assistance from the NSLP in

Page 33: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

33

respective order is region 5, region 3, region 6, region 7, region 2, and finally region 1. The

range between the highest participation region and the lowest participation was nearly two

fold. After running a Pearson’s Correlation test between these two variables (occurrence of

overweight and obesity vs. enrollment in NSLP) the Pearson’s r-value (+.385) indicated a

moderate positive correlational relationship. The correlation is said to have a moderate

positive relationship because the value falls between +.30-.39 (Pearson’s r Correlation, 2012).

While the Pearson’s r value indicates a moderate positive relationship between childhood

obesity and socioeconomic status it must be noted that correlation does not provide causation,

but the data does provide valuable insight on this relationship. As the percent of students that

are eligible for free and reduced priced meals increases as does the occurrence of overweight

and obesity of South Dakota students.

From the results presented in the previous section of this thesis, it can be concluded

that childhood obesity is a significant problem in the South Dakota population; affecting both

males and females and also many different ethnicities alike. The results can also conclude that

families with a low socioeconomic status are more likely to experience being overweight or

obese in childhood, which may be a result of several factors including poor diet, lack of

exercise, family history and environment, and psychological impact. According to the South

Dakota Department of Health;

Childhood overweight and child obesity is a multi-faceted problem that should be

addressed by promoting healthy eating and increasing physical activity and decreasing

inactivity. While it will take South Dakotans working together to overcome this

Page 34: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

34

increasing problem, schools can play a key role in providing education and healthy

environments (Biskeborn, et al, 2011, p. 13).

Discussion

The results of this study are consistent with the epidemic of overweight and obesity

affecting children across the entire USA and developed countries alike, and the conclusions

made in regard to this thesis are similar to the conclusions made by the CDC. Recently, the CDC

reported that around 17% of children nationwide are obese, and that this percentage has

increased exponentially in the past decades (Centers for Disease Control and Prevention, 2010).

In children aged from 6-11 the amount of obesity from 1976-2008 has increased by 13.1%, a

rising trend that proves to be problematic (Centers for Disease Control and Prevention, 2010).

Another finding that was consistent with current research is that socioeconomic status may

contribute to a child’s weight. A low socioeconomic status encompasses several factors that can

contribute to an overweight child, factors outlined by The Southern Medical Journal include

(but are not limited to): health insurance, local schools, local food stores, public transportation,

participation in sedentary activities, and subsidized local, state, and federal programs (Vieweg

et al., 2007). In agreement with The Southern Medical Journal, The CDC also reports that a low

socioeconomic status may influence a higher BMI in children; in a low socioeconomic

environment, one in seven low-income, preschool-aged children is obese, and the prevalence

of obesity in low-income toddlers has increased markedly from the year 1998 to 2003 at an

occurrence 12.4% in 1998 to 14.5% in 2003 (Centers for Disease Control and Prevention, 2010).

Being overweight or obese as a child can not only be detrimental to the mental and emotional

health of child but physically as well. Obese and overweight children experience more severe

Page 35: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

35

health problems at a younger age than the majority of their normal weight peers. Ailments that

affect overweight and obese children include but are not limited to cardiovascular diseases,

type 2 diabetes mellitus, asthma, sleep apnea, and a fatty liver. From these diseases and

ailments overweight and obese children will not only have a poor quality of life at a younger

age but will continue to struggle with this issue into their adult life.

Recommendations

While prevention of childhood obesity should be the ultimate goal for healthcare

providers, families, and schools, the United States still needs to recognize that children are

individuals, and that each child may need a specific plan of care, taking into context all the

factors to why and how the child is at risk or has become overweight or obese. The South

Dakota schools, as well as schools across the United States are encouraged to work with their

local doctors and health representatives to define when and how referrals for evaluation and

intervention should be made on students that are at risk for becoming overweight or obese.

Recommendations for further research would include an investigation of other states on their

socioeconomic status versus the occurrence of childhood obesity, in order to determine

whether or not a low socioeconomic status is indicative to childhood overweight and obesity

across the nation. A longitudinal survey would also be of benefit in order to follow students

from childhood to young adulthood to see if a low socioeconomic status at a young age

correlates with the occurrence of adulthood obesity. Lastly, an outreach program should be

made for those who are receiving aid form the National School Lunch Program in order to

educate both students and families on the importance of healthy eating while maintaining a

Page 36: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

36

budget; having budget friendly healthy alternatives to cheap, convenience, or fast food could

significantly impact the effect of childhood obesity on our nation.

Suggestions for intervention for the prevention and treatment of childhood obesity and

other chronic diseases include increasing the amount of physical activity, decreasing television

viewing, increase fruit and vegetable intake, decrease sweetened beverage intake, decrease

portion sizes, increase breastfeeding, and increase nutrition education in schools both for

families and children. Families regardless of socioeconomic status should be able to provide

their children with healthy food choices for meals and snacks, encouraging children to be

physically active, involving children in selecting and preparing healthful food, involving children

in appropriate activity programs, serving as a role model for children, and limiting television

watching or video games to no more than 2 hours per day (Biskeborn, et al., 2012).

Appendix A:

Directions for Completing School Heights and Weights Data Sheet

School Name and County: Provide full name of school and county in which school is located.

District Name: Report the name of the school district in which the school is located.

Contact Name and Email: This information is needed in case there are questions about the data.

Provide the name of the contact person and their email address.

School Principal’s Name and Email: This information is needed for contact purposes.

2. Date of Measurement: Complete date using month, day, and year. If data was obtained on

September 20, 2010 enter 09 20 2010. Use a separate page for each day data is collected.

Please send data as obtained rather than wait until the end of the school year to send the

recorded data.

Information on each student measured:

Name of student: Remove this information before submitting the data. It is provided for local

school information only.

4. ID#: Each child measured needs a unique identification number. It can just be numerical

order but three digits should be used (i.e., 001, 002, etc). The number is used for data collection

purposes only. Please do not use an ID number more than once for each school.

5. Sex: Enter sex of student as either 1 (male) or 2 (female).

6. Date of Birth: Record person’s date of birth. If date of birth is May 8, 2000, record as follows:

Month Day Year

0 5 0 8 2 0 0 0

7. Ethnic Origin/Race: Enter each student’s race. Complete this by your observation of the race.

Select one or more of the categories listed below:

1 White, not Hispanic

2 Black, not Hispanic

3 Hispanic

4 American Indian or Alaskan Native

5 Hawaiian or Pacific Islander

Page 40: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

40

6 Asian

7 Other

9 Not Specified / Unknown

8. Height: Enter height of individual. Use inches to the nearest 1/8 inch. Do not change

denominator of fraction. Always convert to eighths: 3/4 should be converted to 6/8, 1/4 to

2/8, etc. If height is 45 1/8 inches, record as follows:

4 5 1/8

Allowable entries for numerator of fraction are 0-7. Do not leave blank if zero. Do not use 9 for

an unknown fraction. If height is 62 inches, record as follows:

6 2 0/8

Below is a conversion chart to convert feet and inches to inches. We have added this to the

report form for ease of submitting height in inches, as required.

School personnel should measure height with a metal measuring tape and right-angle

headpiece or full-length measuring board to insure accuracy. Do not use the measuring rod on

the adult balance beam weight scale because it is not accurate. Have individual remove shoes,

heavy outer clothing, hats, and hair barrettes. Procedure:

(1) Have the student stand with his or her back against the wall on a flat floor directly in front of

the measuring tape. The tape should run directly down the center of the back.

(2) Individual should stand with feet slightly apart and the back as straight as possible. The

heels, buttocks, and shoulder blades should touch the wall or surface of the measuring board.

(3) Have individual look straight ahead with head erect but not touching the wall or measuring

board.

(4) Place the headpiece flat against the wall and at a right angle to the head. Lower it until it

firmly touches the crown of the head.

Page 41: Author: Westlie, Mariah J. Title: The Correlation between ... · between family income and obesity prevalence among children and adolescents, although some studies suggest that relationship

41

(5) Hold the right-angle headpiece steady and have the person move out from under it.

(6) Read the measurement at eye level where the lower edge of the headpiece intersects the

measuring tape.

(7) Repeat the procedure until two measurements agree within 1/4 inch. Record the larger of

the two measurements on the form.

9. Weight: Enter weight of individual. Use pounds to the nearest 1/4 pound. Do not change the

denominator of the fraction. Always convert to fourths (1/2 should be converted to 2/4, 4/16 to

1/4, etc.) For example, if weight is 56 1/2 pounds, record as follows:

0 5 6 2/4

Do not leave numerator of fraction blank if zero. Do not use 9 for unknown fraction unless

pounds are unknown also. For example, 125 pounds is recorded as follows:

1 2 5 0/4

Weight should be taken without shoes or heavy outer clothing. Use adult beam balance scale if

at all possible. Scale needs to be placed on uncarpeted floor if possible for an accurate weight.

Child needs to stand on the center of scale platform and not be touching other objects or

person. Child should be weighed, step off the scale, and then weighed again to ensure an

accurate weight.

10. Submit data as soon as possible after measurements are taken, though data will be

accepted throughout the school year until the June 15 deadline. Send all data to:
