We assessed (i) the risk of cardiovascular disease in an industrial population in Chennai, southern India and (ii) whether the status of treatment and control of diabetes and hypertension would be different in an industrial population, which is provided free healthcare, compared with the general population of Chennai. Subjects residing in the residential areas of 2 industries (Indian Airlines and Integral Coach Factory) in Chennai in southern India were recruited. The subjects were employees (n=440) selected by an age- and sex-stratified random sampling method, and their family members (n=727) in the age group of 20–69 years; a total of 1167 subjects. Fasting plasma glucose, lipid estimations and anthropometric measurements were done in all the subjects. Information on demographic and lifestyle determinants was obtained using a questionnaire. Diabetes was diagnosed using the American Diabetes Association criteria and metabolic syndrome was defined by the Adult Treatment Panel III criteria with modified waist definition for Asian Indians. Results. Age-adjusted prevalence of major risk factors for cardiovascular disease using the 2001 Census of India were as follows: diabetes 11.9%; hypertension 25.4%; dyslipidaemia 40.2%; hypertriglyceridaemia 28.3%; overweight (body mass index ³23 kg/m2) 60.2%; and metabolic syndrome 34.1%. Use of tobacco in any form was present in 22.9% of men and 0.5% of women; 79% of the subjects followed a sedentary lifestyle. Among subjects receiving medication, 42.1% of subjects with diabetes and 55.3% of subjects with hypertension had their disease under adequate control. A comparison of these results with the general population of Chennai showed that the industrial population had a higher prevalence of cardiovascular risk factors in spite of having better access to healthcare facilities. Conclusions. The prevalence of cardiovascular disease was high in this industrial population of Chennai. Although the overall treatment and control of diabetes and hypertension was better than that in the general population, it was still inadequate and this emphasizes the need for greater awareness about non-communicable diseases.
