[BDSP. Notice produite par INIST LNR0xfga. Diffusion soumise à autorisation]. Background. The prevalence and determinants of coronary heart disease (CHD) have been inadequately studied in rural areas of developing countries. Methods. Entire communities were surveyed in randomly selected villages in Rajasthan, India. A physician-administered questionnaire, physical examination, and electrocardiogram (ECG) were performed on 3148 adults 20 years of age (1982 males, 1166 females). Fasting blood samples for determination of lipids were obtained from 202 males and 98 females. Prevalence of coronary risk factors-smoking, hypertension, sedentary life-style, ohesity, and hypercholesterolemia-was determined. CHD was diagnosed on basis of past documentation, response to WHO-Rose questionnaire, or changes in ECG. Three methods were used : (a) documentation, history, and ECG criteria, (h) ECG-Q, ST, or T changes, and (c) presence of Q waves. Results. Coronary risk factors : smoking was present in 51% males and 5% females, hypertension ( 140/90 mmHg) in 24% males and 17%, females, hypercholesterolemia ( 200 mg/dl) in 22%, diabetes history in 0.2%, and irregular physical activity or sedentary habits in 85%. Other risk factors were lack of formal education in 44%, obesity (body-mass index 27 kg/m2) in 6% and truncal obesity (waist-hip ratio 0.95) in 5%. The prevalence of CHD (clinical+ECG criteria) was 1.4% in males and 3.7% in females. According to ECG criteria only, it was 2.8% in males and 3.3% in females and according to Q-waves only, it was 1.
