English summary: A cross-sectional study was conducted on 206 children aged 8-10 years (133 normal weight and 73 overweight) to investigate the association between BMI and body fat and abdominal fat and the association between anthropometric indicators and hypertension. The prevalence of metabolic syndrome in overweight children was also addressed. The results showed that overweight and obese children had higher body fat percentage (38.4% vs. 0,8%), waist circumference(86.3% vs. 8.3%), waist/hip ratio (79.5% vs 39.8%) waist/height ratio (82.2% vs 1.5%) compared to normal weight children. BMI has the strongest association with waist circumference and waist/height ratio. The risk of hypertension in overweight children or those with high waist/height ratio was 4.1 times higher than the normal weight or waist/height ratio groups. Among 46 overweight/obese children whose fasting blood was taken, 57.6% of children aged 8-9 years were at risk of metabolic syndrome and 84.6% of children aged 10 years had metabolic syndrome. The prevalence of high blood Glucose and Cholesterol was 43.5% and 34.8%, respectively. Conclusion: The overweight children had higher body fat percentage, abdominal fat and risk of hypertension than those of normal weight group. The overweight children had high prevalence of metabolic syndrome, high blood glucose and cholesterol. Together with BMI, waist circumference and waist/height ratio are good indicators to assess body fat and abdominal fat which are easy to collect. BMI and waist/height ratio are recommended to assess risk of children’s hypertension in the community due to their simplicity in collection and intepration.
