ABSTRACT

Epidemiology is the study of the distribution and determinants of health related status or events in specified population and the application of this study is to control health problems. In occupational epidemiology, the emphasis is on studies of population with particulars type of environmental exposure. Epidemiological studies of occupational workers in tannery industries were contucted to estimate the impact of working condition on the health of the workers. Individual characteristics like sex, age, physical condition, nutrition, personality, genetic factor, disease, lenght of service,nature of work done etc., that modify the effect of environmental factors are taken into consideration. Environmental factors like stress, shift work, human relationship, biological factors like bacterial, virus, parasites, accidental factors like hazard situation, speed, influence of alcohol, drugs and physical factors like noise, climate, work load, lighting, radiation are also taken into consideration. The record of company or trade union are used to study and indenfy indiduals with pas exposure to a specify hazard on the type of work. With the help of such record, retrospective cohort studies were carried out. The epidemiological studies revealed that the workers are suffering with cold feverm flue, headache, body pain, joint pain, demartitis, bronchitis, asthma, acute pharyngitis, acid burn, tuberculosis and injuries. The paritculars of incidence of diseases is more in respect of fever followed by cold & headache. the incidences are more among industrial worker than ther control group. The study also revealed that the workers foresee various diseases which are caused due to exposure to the pollutants in their work places. It is distressing to note that the workers still continue to work even under adverse enviromental surrounding and growing incidence of diseases. it can be related to socio-economic conditon.
