摘　　要：目的验证儿童人体测量指标、体成份与心血管代谢指标间的关联性。方法对174名7-16岁超重肥胖儿童,进行体格检查（包括身高、体重、腰围、臀围）,并计算腰围臀围比值（WHR）、腰围身高比值（WHtR）;使用生物电阻抗体成份测定装置测定体脂率（fat%）;测定血压、清晨空腹血糖、血脂等指标。采用调整性别年龄后的偏相关系数＂r＂表示肥胖指标与心血管代谢指标的关联性。结果 1）各组平均fat%均在30%以上,女生fat%随年龄增加而增加（P〉0.05）。3）身体测量指标、fat%、体质指数（body mass index,BMI）与收缩压和高密度脂蛋白胆固醇（HDL-C）呈现中等程度的相关性（r介于0.30-0.50之间,P〈0.05）;腰围与多数代谢综合征（metabolic syndrome,MS）组份均呈显著相关（P〈0.05）,其次为fat%、BMI和WHtR。结论腰围、体脂率（fat%）MS组份的相关性优于BMI和WHtR,在干预研究中应作为BMI的必要补充。Objective To assess the association between anthropometrical indices and percent body fat （fat%） with cardio-metabolic parameters in overweight Chinese children. Methods One hundred and seventy-four overweight or obese school children （7-16 years old） were recruited in seven Beijing sub-urban primary and secondary schools in 2013. Anthropometrical indices （height, body weight, waist circumference-WC, and hip circumference-HC） were measured and body mass index （BMI）, waist-to-hip ratio （WHR）, and waist-to-height ratio （WHtR） were calculated. Assessment of cardio-metabolic parameters [blood pressure; plasma glucose （GLU）, total cholesterol （TC）, triglyceride （TG）, high-density lipoprotein cholesterol （HDL-C）,and low-density lipoprotein cholesterol （LDL-C）] were carried out with a 12-hour fasting blood sample. Fat% was measured with a bio-impedance body composition analyzer. Partial correlation coefficient-r was used for express the association of anthropometrical indices and fat% to cardio-metabolic parameters after adjusted for age and gender. Results 1） the average fat% in 7- 9,10- 12, and 13 years old over were all at least 30 %, and fat% increased with age increasing（P〈0.05） ; 2）WHtR range was in 0.53-0.56. It was higher in boys than in girls（P〈0.05） ,but there was no significant age differenee（P〉0.05）. 3）anthropometrical indices, fat%, and BMI were moderately associated with systolic blood pressure and HDL-C（r：0. 30-0. 50, P〈0.05） ;WC and fat% were associated to almost all metabolic syndrome （MS） components（P〈0.05） ,more than BMI and WHtR. Conclusion Waist circumference and percent body fat（fat%）are superiorly associated with MS components than BMI and WHtR,and they should be among the core indices in obesity research.
