The course covers topics such as the history of occupational health, occupational lung and skin diseases, health risk assessment, and occupational health legislation. It provides definitions of occupational health as the interaction between work and health. Some key issues in occupational health discussed are technology transfers, child labor, and inadequate safety standards in developing countries. The goals of occupational health are promoting worker well-being, preventing work-related illnesses, and adapting work to people. Occupational health also relates to public health by concerning family and community health impacts. Common work-related diseases include lung diseases, injuries, cancers and cardiovascular disorders. Barriers to identifying

5. DEFINITION
 Occupational health is the study of the
interaction between Work and Health
 About half of man’s waking hours and a third
of his productive years are spent at work
 Work is therefore an essential ingredient of
life

9. CONTEMPORARY ISSUES IN OCCUPATIONAL
HEALTH
1. Technology transfer from industrial to developing
countries or areas within a country;
2. Child labor in developing and developed
countries;
3. Pesticide overuse, toxicity, and food
contamination;
4. Ecological damage from toxic wastes spills and
waste disposal;
5. Toxic waste transfer from industrial to developing
countries;
6. High technology industrial toxic wastes;
7. Nuclear energy, accidents, and wastes;

10. CONTEMPORARY ISSUES IN OCCUPATIONAL
HEALTH…
8. Technological and professional common interest between
occupational and environmental health;
9. Poor safety and control standards in developing countries;
10. Poor wages, psychological stress, boredom, and shift
work;
11. Management negligence and lack of accountability for
workplace safety;
12. Governmental negligence and corruption in developing
regulatory role;
13. Inadequate health and safety measures in developing
countries;
14. Widening income gap between upper and lower income
groups

11. THE AIMS/GOALS OF OCCUPATIONAL HEALTH
 The ILO in 1950 defined the goals of
occupational health as follows:
1. The promotion and maintenance of the highest
degree of physical, mental and social well being
of workers in all occupations
2. The prevention among workers of departures
from health caused by their working conditions
3. The protection of workers in their employment
from risks resulting from factors adverse to health
4. The planning and maintenance of workers in an
occupational environment adapted to his
physiological equipment; and to summarize -the
adaptation of work to man, each man to his job

12. OCCUPATIONAL HEALTH & PUBLIC HEALTH
 Diseases related to occupations,
always an essential part of public
health, increasingly relate to
environmental health, but to other
fields as well
 The worker is also a member of a
family and a breadwinner, so that the
health of the worker is related to
family health

13. OCCUPATIONAL HEALTH & PUBLIC
HEALTH….
 The worker is concerned not only with
what happens at the place of employment
but also with hazardous agents he or she
might accidently bring home
 The retired or laid-off worker is worried
about well-pensioned and honorable
retirement
 Occupational health in this wider context
has an important place in the New Public
Health

14. The Burden of Occupational
Morbidity and Mortality
 The 10 most frequent work-related
diseases and injuries are:
1. Lung disease;
2. Musculoskeletal injuries;
3. Cancers;
4. Severe trauma;
5. Cardiovascular disorders;
6. Disorders of reproduction;
7. Neurotoxic disorders;
8. Noise-related hearing loss;
9. Dermatologic conditions;
10. Psychological strain and boredom.

15. Barriers to Accurate Diagnosis of
Occupational Diseases
 Patient
1. Inadequate training/knowledge of exposures in
workplace
2. Lack of workers access to material safety data
sheets
3. Fear of loss of job due to reporting of illness
4. Psychological denial that symptoms could be work
related
5. Long induction period (the time between initial
exposure to a cause of disease and the occurrence
of disease)
6. Long latency period (the time between the
occurrence of disease and its recognition, whether

16. Barriers to Accurate Diagnosis of
Occupational Diseases….
 Clinician
 Inadequate training/knowledge of exposures in
and diseases found in the workplace
 Inadequate time to conduct occupational
history
 Failure to nconsider occupational factors in
differential diagnosis
 Lack of awareness of the legal requirements
for reporting, notification
 Percieved hassle of reporting to governmental
or surveillance systems

17. Barriers to Accurate Diagnosis of
Occupational Diseases…..
 Societal
-lack of recognition of the scope and costs of
occupational disease in the population in general
-lack of funding of research into chronic diseases
that may be occupationally related
-Historically, the relative isolation of occupational
medicine from traditional medicine care
 Logistics
-loss of reports (eg., in copying, packaging, mail
system, misfiling, and misorting, errors in coding,
data entry, and analysis) between the clinician
and the surveillance officer
