The obese group was more likely to have family histories of obesity, high blood pressure and diabetes; had significantly greater waist-hip-ratio (WHR), higher systolic and diastolic BP, lower HDL-cholesterol, higher triglyceride and fasting insulin levels (with fasting blood sugar in the normal range) than the normal weight group. In a crude analysis, insulin levels were positiveIy correlated with obesity, systolic BP, WHR, age and triglycerides and negatively associated with male gender and HDLcholesterol. After adjustment using multiple regression, only obesity status, age, gender and triglycerides still remained significantly associated with insulin level. Limitation of utilizing family disease history report for identification of children at risk was discussed.Conclusion These findings suggest that risk to coronary heart disease and hypertension through insulin resistance already operates in school-aged children展开更多
