Abstract
AIMS: To estimate the prevalence and distribution of the metabolic syndrome (MS) in adolescents attending school in the north Indian city of Chandigarh. RESEARCH DESIGN AND METHODS: At total of 1083 adolescents attending school (aged 12-17 years) participated in a community-based cross-sectional survey. Anthropometric examination included height, weight, body mass index, waist circumference, hip circumference, waist-hip ratio and blood pressure measurement. A fasting blood sample was taken for measurement of glucose, insulin and lipid profile. Socio-demographic characteristics were investigated using a questionnaire. The metabolic syndrome was determined by the National Cholesterol Education Program Adult Treatment Panel III definition modified for age. RESULTS: The overall prevalence of MS in adolescents was 4.2%. However, the prevalence rose to 5.8% when the fasting plasma glucose cut-off was lowered to 5.5 mmol/l. There was no gender difference in the distribution of MS. When stratified by body mass index (BMI), 5.5% adolescents were overweight (BMI > or = 95th percentile), while 4% were at risk for overweight (BMI between 85th and 95th percentile). Of the overweight adolescents, 36.6% met the criteria for MS, while 11.5% at risk for overweight and only 1.9% of the normal population had MS (P < 0.0001). Low high-density lipoprotein was the most common and abdominal obesity the least common constituent of MS. There was a significant difference (P < 0.0001) between the prevalence of MS adolescents from low to high socio-economic strata. CONCLUSIONS: A substantial number (4.2%) of north Indian adolescents and 36.6% of overweight adolescents had MS. This poses a serious threat to the current and future health of these young people.
