Of course being healthy* means more than merely surviving but as a
starting point for discussion it is hard to avoid the fact that 13 children underthe age of five years die every minute.

and social well-being and not merely the absence of disease or infirmity." [2]

Neonatal care is receiving more attention as greater progress
is made in reducing the burden of disease among olderchildren and as more information is available on the burden ofneonatal disease and interventions that can effectively reduce
this burden.
Most interventions aimed at decreasing neonatal mortality are
linked to prenatal and maternal care interventions. The
interventions that are aimed at reducing childhood mortalitybeyond the neonatal period are typically delivered via public
health programs that we generally think of as more classic
public health delivery methods (e.g. immunization clinics).

Millennium Development Goal #4 (MDG4):Reduce Child Mortality
Page 9
The Millennium Development Goals (MDG) are a set of time-bound targets to
guide countries around the world in a framework for improving health, increasing
development, and reducing poverty. Many of the 8 goals relate to improving thehealth of children—e.g. improving educational opportunities, providing healthenvironments, decreasing poverty and hunger. Recognizing the important role
that child health plays in the overall health of societies, the MDGs include a goal
explicitly aimed at reducing child mortality by two-thirds, between 1990 and 2015.This is MDG #4.

Causes of death also vary from region to region, country to country (and even
among subnational units). For example, malaria is responsible for 7% of childhooddeaths globally; however, it can be the leading cause of childhood deaths in some
endemic African countries.
Proportional mortality data can be misleading if caution is not used in interpretation.
We often use pie charts to visually display causes of death as percentages—i.e.proportional mortality. Remember, proportional mortality only tells you what percent
of deaths are due to a certain cause—it does not tell you about disease incidence or
prevalence and it is not the same as cause specific mortality rates. For example,more than 50% of childhood deaths in the United States are due neonatal causes
compared to Africa where <1/3 of all childhood deaths are due to neonatal causes.However, the number of children who die from neonatal causes per every 1,000
children (i.e. the cause specific mortality rate) is ~3fold in Africa compared to the
US. A disease can kill as many people, but may result in a lower proportionalmortality rate because there are so many deaths due to other causes.

Poverty is defined as either absolute or relative poverty. Both are important
determinants of health.
Absolute poverty is also called abject poverty or destitution and means that basicneeds (e.g. adequate food, shelter, health care) cannot be met.
Relative poverty refers to the inequitable distribution of wealth within a society.Gaps between rich and poor have increased in many countries over the past two
decades. Data from rich and poor countries where there are large gaps betweenrich and poor consistently shows that people living at the bottom economic strata
are more likely to die than those at the top. Living in a setting where some people
are materially deprived compared to others around them is linked to poor health
outcomes. For example, young adult males in Harlem have been shown to havesimilar mortality rates compared to their like aged males in Africa. [8]For more information see WHO Commission on Social Determinants of Health
Final Report[9]

(Discussion of relative vs. absolute poverty is in Part 1 Chapter 2.)

Armed Conflict, cont.
Children are always among the most heavily affected by armed
conflict—either directly or indirectly. Even if they survive thebullets, they are often subject to violence or being orphaned.
The destruction wrought by war disrupts social services such as
education and health care. In a typical five-year war, the U5MR
increases by 13% (and adult mortality by even more). The
aftermath is still evident after the conflict ends; during the firstfive years of peace, the average U5MR remains 11% higher than
it corresponding level before the conflict.

IMCI Case Examples: 18-month old with fever and
lethargyCommunity
Provider
Health System
Community
•
Caretaker at home recognizes that health care is needed
• Health care provider is available in community and family can
afford to pay for services if there are fees
•
Health care provider recognizes symptoms/signs of
complicated malaria, initiates treatment and refers to hospital
for further care. Inquires about use of insecticide treated
bednet in household and advises caretaker regarding its use to
prevent malaria
•
Family able to access hospital care (transportation, costs, etc)•
Hospital facility quickly admits child and starts on appropriate
treatment for complicated malaria
•
Caretaker learns about insecticide treated materials and
implements use for the children in the household.

A multicountry evaluation of IMCI programs found that the 11 day IMCI training course did
positively impact health workers performance. However, the health systems and parent/
caretaker care components were not strongly implemented and were impediments to overall
IMCI effectiveness.

Jones G, et al. How many child deaths can we prevent this year? Lancet 2003
7 in 10 of the 10 million annual deaths in children younger than 5 years are attributable to
six causes: Pneumonia, diarrhea, malaria and 3 neonatal disorders (pre-term delivery,
sepsis and asphyxia.)
2/3 of childhood deaths are preventable with interventions that we already know to be
effective and are feasible for implementation. Things like insecticide treated bednets,
appropriate antibiotics for respiratory infections and antimalarials, access to clean waterand sanitation, oral rehydration therapy for treatment of diarrhea, intermittent presumptive
treatment of malaria during pregnancy, attended births with appropriate care of the
neonate. These prevention and treatment interventions are reviewed in detail in the 2nd
GHEC Child Health Module.

Supplementary Notes
7/26/2019 Child Health Problems Global
http://slidepdf.com/reader/full/child-health-problems-global 75/86
NOTE A -- Why focus on child health?
1) Children represent the most vulnerable societal group for a number ofreasons: a) biologic immaturity—for example, immunologic immaturity putthem at increased risk of infectious diseases, b) they are at risk of insults
which can arrest or retard their physical and mental development, c) theyare dependant on adults for their optimal development and in fact survival. As a result of their vulnerability and dependence on society and adults fortheir care, the UN Convention on the Rights of the Child (UNCRC) wasdrafted and presented in 1989 with all countries signing the Conventionand all but 2 countries’ governments (US and Somalia) ratifying theConvention. At the time of this writing, the new US Presidential
Administration has indicated that they will review the document forratification reconsideration. However, ratification requires Congressionalapproval in the US as well. For more information seehttp://www.unicef.org/ceecis/overview_1583.html for an overview and
http://www.crin.org/docs/resources/treaties/uncrc.asp for the full text.
2) Improvements in child health are a good measure of societal progress—hence the Millennium Development goals (described later in Note F)contains a specific goal explicitly stating the need to reduce childhoodmortality as well as other goals relating to children as well (i.e. improvingeducation rates, reducing poverty rates). Infant and child mortality rates(discussed in later slide and note C) have traditionally been (and still are)used as sensitive markers for the overall health of nations as a whole.
3) GHEC Module 21 reviews the Global Burden of Disease* and commonways to measure that burden including life expectancy and disability-adjusted life years (DALYs)1. Childhood illness, disability, and death areimportant components of the global burden of disease; death duringchildhood substantially contributes to reduced life expectancy indeveloping countries. Furthermore, childhood illness is an importantcontributor to the global burden of disease. For example, the key causesof childhood morbidity are estimated to account for 14% of DALYs [1].
4) 2/3 of childhood deaths are preventable and/or treatable with interventionsthat are currently available! Read on for more information!
*For more information about the Global Burden of Disease Project see:
Return to Slide 3
1 DALY is a weighted index that takes into account loss of life, morbidity and disability.

NOTE B -- Indicators of childhood mortality
DEFINITIONS, DEFINITIONS—LET’S GET A HANDLE ON THE LINGO USEDTO MEASURE CHILD HEALTH OR LACK THEREOF
An indicator is a commonly used term in public health that refers to a measureof health or disease. Incidence and prevalence rates and different types ofmortality rates are commonly used indicators. For example:
o Proportional mortality = number of deaths due to a specific cause in adefined population over a year / total number of deaths occurring in thatpopulation during the same year
o Mortality rate = number of deaths due to a specific cause in a definedpopulation over a year/ total number in the defined population at themidpoint of the same year = probability of dying due to a specific cause
in a given populationo Note that proportion dying and probability of dying from a given cause are
very different! For example, 3% of childhood deaths in developingcountries are due to injuries vs. 10% in developed countries. So, areinjuries an important problem in developing countries? Doesn’t seem likeit if you just look at proportional mortality of 3%. However, the risk orprobability of a child dying from injuries is greater in developing countriesthan it is in developed countries!! In other words, more children/population are at risk of fatal injuries in developing countries than indeveloped countries. It’s just that they are also dying from other causes athigher rates, so the importance of injuries as a contributor to mortality ismasked if you just look at proportional mortality.
In child health the 3 most used common mortality indicators are:
• Under five mortality rate (U5MR) is also referred to as child mortalityrate (CHR) = number of deaths under five years of age in a definedpopulation over a year / number of live births occurring in that populationduring the same year
• Infant mortality rate (IMR) = number of deaths under one year of age in adefined population over a year / number of live births occurring in thatpopulation during the same year
• Neonatal mortality rate (NMR)= number of deaths under 28 days of agein a defined population over a year / number of live births occurring in thatpopulation during that same year
Note the differences in the definitions of the denominators between the childmortality rates and general mortality rate. Note also that NMR is encompassedwithin IMR and U5MR, and NMR and IMR are encompassed within U5MR.

NOTE C -- Reminder -- Morbidity
IODINE Deficiency is the single most important cause of preventable braindamage and mental retardation. It significantly raises the risk of stillbirth and
miscarriage in pregnant women. 43 million people worldwide suffer from varyingdegrees of brain damage and physical impairment due to iodine deficiency—there is a spectrum of associated disability. The primary intervention for thecontrol of IDD is through salt iodization. For more information on IDD seehttp://www.childinfo.org/idd.html
VITAMIN A Deficiency is a contributing factor in 2.2 million deaths each yearfrom diarrhea and 1 million deaths from measles among preschool children underfive. Severe deficiency can also cause irreversible corneal damage, leading topartial or total blindness. Vitamin A deficient children face a 23% greater risk ofdying from ailments such as measles, diarrhea or malaria . Vitamin A
supplementation of children with can reduce deaths from diarrhea and measlesby
35-50% and 50%, respectively. Treatment with high dose vitamin A is animportant component of measles case management. For more information onvitamin A deficiency see http://www.childinfo.org/vitamina.html
IRON Deficiency is the most common nutritional disorder in the world. It lowersresistance to disease and weakens a child's learning ability and physical stamina.It is a significant cause of maternal mortality, increasing the risk of hemorrhageand infection during childbirth. Nearly 2 billion people are estimated to beanemic and millions more are iron deficient, the vast majority are women andchildren. For more information seehttp://www.unicef.org/nutrition/23964_iron.html
HELMINTHIC infections are an important cause of poor growth and anemiaworldwide. Hookworm infection, for example, is an important cause of anemia inmany settings with clinical manifestations similar to that of iron deficiencyanemia. Periodic presumptive treatment among schoolchildren can lead tocontrol in endemic settings. For more information on helminthiasis seehttp://www.who.int/topics/helminthiasis/en/
Furthermore, many common causes of child mortality can leave survivors withlong term disabilities: for example, reduced cognitive function post cerebralmalaria, intestinal malabsorption as a result of prolonged or recurrent diarrhealinfections leading to poor nutrient absorption, disabilities secondary to injuries.

Progress is being made in reducing childhood mortality. Between 1980 and 2008annual child deaths worldwide decreased from 13.5 million to 8.8 million. Latin
America, the Caribbean, Eastern Europe, the Pacific and East Asia are on track
for meeting MDG4.
Worldwide, there has been a 41% reduction in U5MR from1990-2011. In somecountries progress had stalled or even reversed in the 1990’s (e.g. Kenya, South
Africa, Zimbabwe, Rwanda, Swaziland)—often due to conflict, political instabilityleading to reduced focus on public health infrastructure, and/or the HIV/AIDSepdemic.
However, of 66 countries with child mortality rates of at least 40 per 1,000 livebirths, 20 have reduced their under-five mortality rates by at least half between1990 and 2011, and 4 of them have achieved at least a two-thirds decline (in
Lao People’s Democratic Republic, Timor-Leste, Liberia and Bangladesh) [4].For more information see http://www.childinfo.org/mortality_underfive.php .

NOTE E -- Slowing trends in improvements in child mortality
Reductions in mortality rates during the 1960s-1970s and into 1980s providedoptimism that MDG #4 could be realistically met by 2015. However, progressslowed in the 1980s and 1990s [5, 6], picking up at a somewhat better pace
during the first decade of this century—but not at a pace fast enough to meetMDG4 by 2015 at current rates. Globally, rates of reduction in under-fivemortality decreased by an average of 1.8 percent per year between 1990–2000.Progress improved over the next decade with an average 3.2 percent decreaseper annum from 2000–2011. However, in order to meet MDG4 an annual rate ofreduction in child mortality of 14.2% would be needed.
Of 66 countries with the highest mortality rates, only 15 are on track to meetMDG4.
Meeting the target will require serious commitments to implementing life-saving
interventions and tackling the social determinants of health. But it can be done,even in the poorest of environments. The following are examples of high mortalitycountries have made great strides forward in reducing under-5 mortality: Nepal,Timor Leste, Bangladesh, Eritrea, Lao People’s Democratic Republic, Mongolia,Bolivia, and Malawi.

NOTE F -- Undernutrition is an Important Underlying Cause of Death
Undernutrition* typically is not directly responsible as a cause of death, moreoften it is a very important underlying cause of death. Altogether undernutritioncontributes to 35% of childhood deaths [7]. Undernutrition puts children at
increased risk of illness (e.g. increased risk of contracting pneumonia, diarrhea,malaria) and once they are sick puts them at even greater risk of dying.
Undernutrition can take many forms. While poor caloric and macronutrient(protein, fat, carbohydrate) intake is an obvious cause of undernutrition (definedas low weight for age), micronutrients also play an important role in promotinggrowth and micronutrient deficiencies can also lead to low weight for age. Inaddition, micronutrient deficiencies can be present in children who are notunderweight. Micronutrient deficiencies are associated with increased risk ofmorbidity and mortality—for example increased risk of getting ill with diarrheaand increased risk of dying from measles, respiratory infections, and diarrhea.The most common micronutrient deficiencies are vitamin A, zinc, iron and iodine.
Breastfeeding also plays an important role in health promotion and diseaseprevention. Infants less than six months who have not been breastfed have a 7-fold and a 5-fold risk of dying from diarrhea and pneumonia, respectively,compared to children who have been exclusively breastfed. Those who havebeen breastfed but not exclusively, face a 2-fold increased risk compared tothose who have been exclusively breastfed. For more information onbreastfeeding see http://www.childinfo.org/breastfeeding.html
Undernutrition also inhibits physical and mental development. It is also a majorcause of neonatal morbidity and mortality as malnourished girls and women withstunted growth have increased risk of obstructed labor as well as low birth weight
babies.!The term malnutrition encompasses overweight, obesity and undernutrition. The
term undernutrition refers to calorie/macronutrient deficiency, micronutrientdeficiency and lack of exclusive breastfeeding. Infants 6 months and older alsobenefit from breastmilk in their diet in terms of protection from mortality.

NOTE G -- Examples of Intervention Delivery Methods
Primary Health Care (PHC) refers to a specific movement originating in the late1970’s which defined a goal of “Health for All by the year 2000” via the Alma Ata
Declaration which was signed by 134 health ministers from around the world andendorsed by WHO, UNICEF and major funding organizations. The goal was tobe realized via the provision of essential health care (e.g. access to care fortreatment of common conditions) and basic public health services (e.g.immunizations, clean water, sanitation facilities) as well as tackling underlyingcauses of death such as poverty and illiteracy. PHC involves an integratedapproach to the delivery of services at the community level but as a part of acomprehensive national health system.

NOTE H -- Examples of Intervention Delivery Methods
Following the Alma Ata declaration, there was concern (for example amonggovernments with a vested political interest in preserving inequities as well asamong influential US international health experts) that PHC was too ambitious a
project, and that there needed to be a focus on delivering specific selectiveinterventions—referred to as selective cost effective interventions (SPHC).SPHC movement focused on the technological aspects of the interventions. Theroles of communities, socio economic development and addressing underlyingdeterminants of health are not by SPHC. In the 1980’s UNICEF adopted aSPHC child survival strategy termed GOBI (growth monitoring, oral rehydrationtherapy and immunization). This was expanded to include family planning, foodsupplements and female education (GOBI-FFF). SPHC programs are oftendelivered as vertical programs—i.e. not an integral part of the health care andpublic health system in developing communities but rather as isolated andindependent programs.
Vertical programming often results in human resources being diverted from day-to-day management of PHC operations in order to devote time and attention tothe vertical intervention being promoted at that time. Vertical programming isdifficult to sustain without continued carry-through via a functioning healthsystem.

NOTE I -- Integrated Management of Childhood Illnesses (IMCI)
In the 1990’s UNICEF and WHO started promoting the Integrated Managementof Childhood Illnesses (IMCI) approach which might be viewed as a pendulumpartial swing back toward PHC—community involvement is emphasized although
underlying social, political and economic causes of poor health are not welladdressed. IMCI is “an integrated approach to child health that focuses on thewell-being of the whole child. IMCI aims to reduce death, illness and disability,and to promote improved growth and development among children under 5 yearsof age. IMCI includes both preventive and curative elements that areimplemented by families and communities as well as by health facilities.” Inhealth facilities, the IMCI strategy promotes the accurate identification ofchildhood illnesses in outpatient settings, ensures appropriate combinedtreatment of all major illnesses, strengthens the counselling of caretakers, andspeeds up the referral of severely ill children. In the home setting, it promotesappropriate care-seeking behaviours, improved nutrition and preventative care,
and the correct implementation of prescribed care.
There are 3 components to IMCI:• improving health worker skills
o IMCI trainings are structured 11 day courses aimed at teaching healthcare workers in the community (i.e. primarily the non-physicianproviders (e.g. nurses) who provide the majority of care in manydeveloping countries.
o The courses cover IMCI protocols in identifying the commonpresentations of the sick child as well as appropriate treatment, follow-up and referral for these conditions.
o The courses and IMCI protocols also have components on assessing“well child issues”--growth, nutrition, development, and immunizations.The protocols encourage health workers to check immunization/growthchart cards during sick visits to assess for and growth faltering, gaps inimmunizations or routine vitamin A doses, delays in development(developmental milestones are included on these cards. Appropriatetreatment and referral are included in guidelines.
• improving home and community based care and practices to ensure that:o appropriate prevention strategies such as exclusive breastfeeding for 6
months, appropriate nutrition, use of insecticide treated materials arebeing practiced
o home based care is appropriate for both the sick child (e.g. appropriateantimalarials for the febrile child in a malaria endemic setting, oralrehydration therapy for the child with diarrhea and no dehydration)
o children are taken promptly to a health worker when symptoms andsigns of illness warrant health care (e.g. symptoms of complicatedmalaria--fever and poor feeding, fever and lethargy or diarrhea withsigns of dehydration (poor ability to drink, lethargy, etc)

http://slidepdf.com/reader/full/child-health-problems-global 85/86
o children are given full courses of prescribed treatments (e.g. full courseof appropriate antibiotics prescribed by health worker for respiratoryinfection, full course of appropriate anti-malarials
• improving health systemso appropriate supervision of and continued training for health workerso
procurement systems with adequate supplies of medications, vaccinesand supplieso referral facilities (i.e. hospitals) that respond to referrals from the
community level. Mechanisms must be in place to efficiently respondto the sick child who is referred from the community.
Standard IMCI protocols share common features (e.g. identification of childneeding antibiotics for treatment of respiratory infection and symptoms/signsrequiring hospital referral), but protocols are also setting specific (e.g. includesassessment and treatment for dengue fever in endemic settings)

Note J -- IMCI Case Examples: 18-month old with fever and lethargy
Preliminary Data from 5 countries that where an evaluation of IMCI is takingplace are encouraging in regards to training of health workers but the healthsystems component of IMCI is just not strong enough to deliver an effective total
IMCI package. Access to care presents another significant impediment to IMCIeffectiveness.
Case example: An 18 month old presents with fever and lethargy. In order forIMCI to be effective in helping this child, the caretaker needs to identify that thechild is ill and seek care. The community health worker must be trained torecognize severe malaria based on clinical presentation and initiative immediatetreatment and referral to a health care facility. The family must then be able toaccess the facility and the facility must recognize the condition and treat the childappropriately.
Case example: An 8 month old presents cough and fever. Again, the familymust recognize that this is a condition for which care should be sought and carewithin the community should be accessible. The community health workershould not only be able to follow clinical algorithm leading to a clinical diagnosisof pneumonia but should also assess the growth and immunization record andgive nutrition advice and update immunizations accordingly. The communityhealth worker should also document developmental progress on the growth chartand intervene if there is developmental delay. If the child is from a malariaendemic setting treatment for potential concomitant malaria is included in theclinical care guidelines as well.
In IMCI care is more comprehensive. Community education regarding healthypractices is important and encompassed in 16 “key family practices for healthygrowth and development” that fall into 4 categories: promote physical growthand mental development, promote disease prevention, promote appropriatehome care, and promote health care seeking behavior. For a full list of the 16key community IMCI family practices see http://www.paho.org/english/ad/fch/ca/GSIYCF_keyfam_practices.pdf
