基于生物电阻抗法测量的体脂肪量对儿童血压和血糖代谢异常的预测价值
Value of body fat mass measured by bioelectrical impedance analysis in predicting abnormal blood pressure and abnormal glucose metabolism in children
目的 探讨基于生物电阻抗法（BIA）测量的儿童体脂肪量对血压和血糖代谢异常的预测价值。方法 采用分层整群抽样的方法选取6~16岁学生进行问卷调查和体格测量，通过BIA仪器测量体脂肪量，计算体重指数（BMI）、体脂肪指数（FMI）和体脂肪率（FMP），并检测空腹血糖水平。结果 纳入的14 293名儿童中男童占49.89%。在男女儿童中分别以FMI和FMP通过LMS法拟合的百分位数值（P60、P65、P70、P75、P80、P85、P90、P95）逐个作为切点，受试者工作特征曲线分析显示，对血压异常和血糖代谢异常预测价值较好的体脂过多切点为P70值。控制FMI或FMP在P70以下，可减少8.53%~43.24%的儿童发生血压和血糖代谢异常。结论 基于FMI和FMP评价肥胖状态对于儿童高血压和高血糖筛查具有一定的公共卫生价值，在今后儿童肥胖和相关慢性疾病防治工作中可进一步验证。
Objective To study the value of body fat mass measured by bioelectrical impedance analysis (BIA) in predicting abnormal blood pressure and abnormal glucose metabolism in children. Methods Stratified cluster sampling was used to select the students aged 6-16 years, and a questionnaire survey and physical examination were performed. The BIA apparatus was used to measure body fat mass. Body mass index (BMI), body fat mass index (FMI), and fat mass percentage (FMP) were calculated. Fasting blood glucose level were measured. Results A total of 14 293 children were enrolled, among whom boys accounted for 49.89%. In boys and girls, the percentile values (P60, P65, P70, P75, P80, P85, P90, P95) of FMI and FMP fitted by the LMS method were taken as the cut-off values. Based on the receiver operating characteristic curve analysis, the P70 values with a better value in predicting abnormal blood pressure and blood glucose metabolism were selected as the cut-off values for excessive body fat. When FMI or FMP was controlled below P70, the incidence of abnormal blood pressure or abnormal glucose metabolism may be decreased in 8.25%-43.24% of the children. Conclusions The evaluation of obesity based on FMI and FMP has a certain value in screening for hypertension and hyperglycemia in children, which can be further verified in the future prevention and treatment of obesity and related chronic diseases in children.
