Abstract: 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 difference(P>0.05).3)anthropometrical indices,fat%,and BMI were moderately associated with systolic blood pressure and HDL-C(r0.30-0.50,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.

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);2)WHtR为0.53~0.56,男生高于女生(P<0.05),无年龄差异(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。
