Prevalence of atherosclerosis risk factors in adolescent school children

The emerging epidemic of atherosclerotic cardiovascular diseases in developing countries may have its roots in childhood. We studied atherosclerosis risk factors--tobacco use, obesity, hypertension, total cholesterol level and dietary intake of atherogenic nutrients in adolescent school children aged 13-17 years in Western India. Two hundred thirty-seven children (89 boys, 148 girls) were examined and prevalence of risk factors determined. Family history of coronary heart disease was found in 16 (6.8%), smoking or tobacco use in one (0.4%) and obesity (BMI > 90th percentile) in 24 (10.1%), borderline hypertension (> or = 136/86) in 65 (27.4%) and definite hypertension (> or = 142/92) in 17 (7.2%). Borderline hypercholesterolaemia (170-199 mg/dL) was in 78 (32.9%) and definite hypercholesterolaemia (> or = 200 mg/dL) in 16 (6.8%). Mean calorie intake was 1450 +/- 348 per day. Fats provided 38.4 +/- 8 percent of the calories, saturated fats contributed to 20.3 +/- 6.4 percent of calories, monounsaturated fats to 12.9 +/- 2.4 percent and polyunsaturated fats to 5.0 +/- 3.7 percent. Dietary cholesterol intake was 164 +/- 95 mg/day, sodium chloride intake 12.8 +/- 5.7 gm/day and fibre intake 6.5 +/- 4.6 gm/day. This study shows a high prevalence of metabolic and dietetic coronary risk factors among adolescents of the middle- and upper-middle class in India.
