Purpose : This study was designed to characterize the nutritional status and obesity and to determine the relationship between obesity and serum lipid profiles in early school-age children. Method : In 2007, we surveyed 483 children (233 boys and 250 girls) aged 6-7 years. Total cholesterol, triglyceride, and HDL-cholesterol were measured in fasting. Dietary information was obtained by questionnaire. Results : The prevalence of obesity was 9.9%, there was no significant difference between sex groups. Mean caloric intakes was 1781kcal in boys and 1640kcal in girls. The prevalence of excessive calorie was 33% in boys and 30% in girls. The prevalence of total cholesterol ≥200mg/dL was 8.4%; that of TG≥130mg/dL, 5.0%: that of LDL-cholesterol≥130mg/dL, 3.1%; that of HDL-cholesterol<35m g/dL, 4.4%. The prevalence of hypertension was 2.1%. There was no significant difference between sex groups. Systolic blood pressure, Triglyceride and LDL-cholesterol were significantly related to increased obesity index(p<0.05). Mean caloric intakes and nutritive component were not related to obesity index. The obesity group were compared to control group and if there was Triglyceride≥130mg/dL, Odd ratio was 4.08; LDL-cholesterol≥130mg, that was 2.85; TC/HDL-cholesterol≥4.0, that was 1.16. BMI and triglyceride in hypertension group were respectively higher(p<0.05). There were significant positive correlations between BMI and blood pressure, LDL-cholesterol, Triglyceride(p<0.05). BMI was not correlated with mean caloric intakes and nutritive component. Conclusion : The prevalence of hypertension and hyperlipidemia in early school-age children were significantly related to increased obesity index. The management of obesity in early school-age children need to minimize risk of hyperlipidemia and hypertension. Key Words : Obesity, Hyperlipidemia, Hypertension
