Prevalence of atherosclerosis risk factors in adolescent school children

Abstract

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.
