6. Brief Resume of Intended Work :
6.1 Need for Study :
“We know lots of thing we didn’t use to know, but we don’t know anyway to prevent’em happening” – Will Rogers.
Asthma, a Greek word meaning- "panting", is a common chronic
inflammatory disease of the airways characterized by variable and recurring
symptoms, reversible airflow obstruction, and bronchospasm. Symptoms
include wheezing, coughing, chest tightness, and breathlessness. Asthma
attacks all age groups irrespective of the gender.1
Asthma differs from the other obstructive pulmonary disease in that it is
largely reversible, either spontaneously or with treatment. Patients with
asthma may experience symptom free periods alternating with acute
exacerbations that last from minutes to hours or days. For most patients
asthma is a disruptive disease, affecting school and work attendance,
occupational choices, physical choices, physical activity and general quality
of life.2
According to World Health Organization between 100-150 million people
around the globe-roughly the population of Russian Federation-suffer from
asthma, the number is still rising. Worldwide, deaths from asthma have
reached over 18000 /a year. Studies show that 1 in 7 children, and 1 in 12
adults, suffer from asthma.3
As per the National Institute of Health and Family Welfare of India statistics,
there is 100 million occupational injuries causing 0.1 million deaths in the
world. It also estimated that in India 17 million occupational non –fatal
injuries, 17% of world, and 45000 fatal injuries i.e., 45% of total deaths due
to occupational diseases in world occur each year. Out of 11 million cases of
occupational diseases in world 1.9 million cases,17%, are contributed by
2
India and out of 0.7 million death in the world 0.12 million is contributed by
India.4
According to National Institute of Health and Family Welfare the adverse
occupational factors have been estimated to cost 2-14 % of the gross national
products for various countries. As the incidence of occupational related
mortality is high in India it is false to say that out of total One million crore
Rupees of Gross National Product in the year 1999, occupational disease
caused a loss of 70000 crore. The amount paid as compensation for death and
disablement resulting from work related injuries in India has increased from
Rupees 8 million in 1961 to Rs.186 million in 1997.Occupational asthma
plays a very significant role in this diseases.4
A study conducted to thoroughly examine the effects of occupational
exposure to cement dust on the respiratory system. The study population
consisted of a group of 88, randomly selected, male workers with current
exposure to cement dust and 80 healthy male office workers without present
or past history of exposure to dust that served as the referent group. Subjects
were interviewed, underwent chest X-ray and lung function tests. X-ray
diffraction and X-ray fluorescence techniques were performed to determine
the silica phases and the SiO2 contents of the dust samples. The results
showed that symptoms like regular cough, phlegm, wheezing and shortness of
breath were significantly more prevalent among exposed workers. Similarly,
chest radiographs of exposed workers showed various degrees of
abnormalities including emphysematous changes, old calcified granulomas,
emphysematous changes associated with inflammatory processes, evidence of
chronic inflammatory processes, focusal calcification of the lungs and
infiltrative changes. The researchers concluded that, exposure to cement dust
is associated with respiratory symptoms and functional impairments.5
A study was conducted to assess the chronic respiratory symptoms and
chronic obstructive pulmonary disease /asthma among workers exposed to
cement dust at a Tanzanian cement factory. The study population consisted of
a total of 120 exposed workers and 107 control participants. Information on
3
demographics, occupational history, chronic respiratory symptoms/asthma,
smoking habits, and use of respiratory protection equipment was collected by
questionnaire. Ventilatory function testing and measurement of personal total
dust exposure were carried out. Chronic obstructive pulmonary disease was
diagnosed for workers with chronic bronchitis who also had spirometric
airflow obstruction. The results showed that the exposed workers had more
chronic cough, chronic sputum production, dyspnea, work-related shortness
of breath, and chronic bronchitis than the controls. The researchers concluded
that the cement workers seem to be at high risk of developing chronic
respiratory symptoms, asthma and, chronic obstructive pulmonary disease
probably caused by cumulative total dust exposure independent of smoking
habits.6
A cross-sectional study was conducted to determine the prevalence of
respiratory symptoms or diseases and chest x-ray changes consistent with
pneumoconiosis in the employees. A sample of 150 exposed and 355
unexposed employees were selected. A questionnaire about respiratory
symptoms was completed during an interview. Chest x-rays were read
according to the International Labour Organization criteria for
pneumoconiosis. The results showed that cough and phlegm are associated
with smoking habits. The researchers concluded that wheezing, shortness of
breath, and bronchial asthma were related to dust levels and engineering
measures be adopted to reduce the cement dust level in the company, together
with health monitoring of exposed employees.7
Researches In India Related To Cement Industries:
A study was done to evaluate the effect of cement exposure on ventillatory
function of workers in Diamond Cement factory. The study population
included 136 cement factory workers who were selected randomly. All
underwent extensive clinical and physical examination. After all exclusion
procedures 2 final study groups were constituted: that included a group of 40
smokers, group of 60 non smokers, and 50 controls. The results showed that
ventillatory functions were impaired more in patients exposed to cement
particles and smoking increases the impairments of ventilatory function. The
researcher concluded that in the study samples 15-20% cases were asthma and
4
chronic obstructive pulmonary disease and the management should take
accurate measures to prevent or decrease respiratory diseases like asthma in
occupational settings because once the disease occurs then there is no cure.8
The above studies show that there is large percent learning needs among the
workers regarding the prevention of asthma. This study is to evaluate the
effectiveness of structured teaching programme regarding the prevention of
bronchial asthma among the workers in cement industries because same like
cement production company workers they also are facing the hazards from
cement dust along with other air pollutants in the work environment. Lack of
knowledge and non availability or improper use of personal protective
measures increases the risk.
6.2 Review of Literature :
A study was conducted to investigate the associations between "total" dust
exposure and acute respiratory symptoms and respiratory function among
cement factory workers.40 exposed production workers from the crusher and
packing sections and 20 controls from the guards were included as the
sample. Personal "total" dust was measured in the workers before and after
the shift. The results showed that highest geometric mean dust exposure was
in the crusher section: 38.6 mg/m3 followed by the packing section: 18.5
mg/m3 and the guards: 0.4 mg/m3. Of these samples 85% had stuffy nose,
47% shortness of breath and 45% had sneezing. Peak expiratory flow was
decreased significantly across the shift in the high exposed group. The
number of years of work in high-exposure sections was associated with cross-
shift decrease in peak expiratory flow. The researchers concluded that total
cement dust exposure was related to acute respiratory symptoms and 0acute
ventilatory effects.9
A study was conducted to assess the effects of cement dust exposure on acute
respiratory health. The study was conducted on 51 high exposed and 33 low
5
exposed male cement workers. Acute respiratory symptoms were recorded by
interview using a structured optimal symptom score questionnaire. Peak
expiratory flow was measured preshift and post shift for each worker with a
Mini-Wright Peak expiratory flow meter. The results showed that geometric
means of personal respirable dust and total dust among high exposed were 4.0
and 13.2mg/m, respectively, and 0.7 and 1.0 mg/m among low exposed. High
exposed workers had more acute cough, shortness of breath and stuffy nose
than the low exposed. Mean percentage cross-shift decrease in Peak
expiratory flow was significantly more pronounced among high exposed
workers than low exposed. The researchers concluded that acute respiratory
health effects among the workers are most likely due to exposure to high
concentrations of irritant cement dust.10
A study was done to determine the occupational hazards of cement dust on
the lungs of cement mill workers. The study population consisted of 50;
apparently healthy volunteer male cement mill workers who were randomly
selected with an average of 13 years exposure with age ranging from 20-60
years. They were matched with 50, healthy male control subjects in terms of
age, height, weight and socioeconomic status. Radiology was performed by
Trophy radiology. The results showed that 12% of cases with interstitial lung
disease and 2% of cases with pleural thickening and chronic bronchitis
/asthma in cement mill workers. The researchers concluded that exposure to
cement dust cause asthma, interstitial lung disease and chronic bronchitis in
cement mill workers.11
A study was conducted to determine the prevalence of respiratory symptoms
and to propose some preventive measures among the workers in cement
factory. The study was done on a group of workers of whom 280 were
exposed to cement dust and 73 who were not. The results showed that 65% of
those exposed had clinical symptoms as opposed to 34.2% of the non-
exposed. Cough, expectoration rhinitis, chronic bronchitis and asthma were
significantly more common with incidences of 56.1%, 52.5%, 49.3%, 29.3%
and 14.3% respectively in the exposed against 19.2%, 24.6%, 26%, 9.6% and
6.8% in the non-exposed. Among the exposed the prevalence of chronic
bronchitis increased significantly with the degree of exposure, from 11.4% in
6
category 1 to 41.6% in category 3. Age did not seem to influence the
development of chronic bronchitis but on the other hand a smoking history of
more than 10 years did. The researchers concluded that incidence of
abnormalities of respiratory function is significantly higher in the exposed
than in the non-exposed and prevention depends therefore on a programme of
technical; collective and individual and medical protection of the workforce.12
A study was conducted to investigate possible health effects, respiratory
symptoms and lung function in laborers, tunnel workers, and operating
engineers in highway and tunnel construction due to dust exposure. Based on
self-report, asthma and chronic bronchitis were categorized for asthma, (1)
physician-diagnosed or (2) undiagnosed likely, and (3) for chronic bronchitis
symptomatic. They checked the prevalence of asthma and chronic bronchitis,
lung function outcome. The results showed that from 389 workers: 186
laborers, 45 tunnel workers, and 158 engineers prevalence of asthma was 13
and 11.4% for laborers and engineers, respectively, and of symptomatic
chronic bronchitis, 6.5 and 1.9%, respectively. Undiagnosed asthma was
significantly elevated in workers compared to engineers, and marginally
elevated for chronic bronchitis. The study concluded that exposure to cement
products or its dust may predispose workers in developing asthma and
associated respiratory problems.13
Another study was conducted to the dust reactions resulting from the products
such as sand, gravel and cement .The study was conducted in a male
population: 120 employees working in cement production and 120 non-
exposed civil servants. The results showed that an increase in the prevalence
of exposed symptomatic subjects 57.5% compared to non-exposed subjects
24.2% and increased prevalence of all of the symptoms: cough 15.8% vs.
15%, dyspnea 21.6% vs. 5%, chronic bronchitis 11.7% vs. 6.7%, asthma
14.2% vs. 7.5%, rhinitis 40% vs. 19.2%, conjunctivitis 48.3% vs. 10% and
dermatitis 22.5% vs. 6.7%. Changes in lung function parameters were much
more frequent among the workers at the two factories than among the non-
exposed workers 40.8% and 11.7% respectively. Tobacco also seemed to
have an effect on respiratory deficit. Analysis of the chest radiographs of the
7
exposed subjects, using the international classification, revealed 15.8%
abnormal films. The researchers concluded that working conditions in cement
factories must be improved rapidly and recommended setting up of medical
service for regular management and follow-up of the workers.14
A study was conducted to investigate the effect of dust exposure on
ventilatory lung function of Portland cement factory workers. The study
group included 62 male workers, exposed to cement dust and 70 subjects
from unexposed group of workers. The result showed that significant
differences in spirometry values between the exposed and unexposed groups.
The workers showed (i)significantly lower forced expiratory volume 1% and
forced expiratory flow 25-75%, and ii) reduced forced expiratory volume 1%
with increasing level of dust exposure and iii) higher prevalence of respiratory
symptoms like asthma. The researchers concluded that exposure to dust in the
cement factory leads to higher incidence of respiratory symptoms and
impaired lung function.15
A study was conducted to assess respiratory symptoms and pulmonary
function in a cross-sectional survey of 348 Portland cement workers in
Jordan. About 42% of the workers reported various chronic respiratory
symptoms, but cough, dyspnea, and asthma were most prevalent 18.7%,
17.5% and 15.8%, respectively. The results showed that asthma was
significantly associated with the age of 30-39 years and showed a
proportionate association with exposure level. The researchers concluded that
inhalation of cement dust irritates the respiratory tree without markedly
affecting lung function, and smoking aggravates the effect.16
A study was conducted to assess the relationship between occupational
Portland cement dust exposure and respiratory health. Respiratory symptoms
and ventilatory function were studied in a group of 591 male Portland cement
workers employed in four cement plants. The prevalence of chronic
respiratory symptoms was higher in exposed than in control workers. The
results showed that exposed group had a significantly lower mean forced vital
capacity, forced expiratory volume and forced expiratory flows after
8
exhalation of 50% and 75% of the vital capacity than the control group. The
researcher concluded that occupational exposure to Portland cement dust may
lead to higher prevalence of chronic respiratory symptoms and the reduction
of ventilatory capacity.17
