目的阐明儿童期BMI及体成分指数与血压水平的相关性,为成年期疾病的早期预防提供相关依据。方法对济南市910名7岁儿童进行身高、体重、血压和皮褶厚度测量,采用回归方程推算体脂比(BF%),计算脂肪组织指数(FMI)和非脂肪组织指数(FFMI)。结果 BMI,BF%,FMI,FFMI与收缩压和舒张压均呈一定程度正相关(P值均<0.05),血压与FMI的相关性高于FFMI。高BMI、BF%百分位数组儿童的血压水平均显著高于低百分位数组(P值均<0.05)。血压偏高的检出率为肥胖组>超重组>正常组>消瘦组。结论儿童BMI及体成分指数与血压水平有显著的相关性。预防儿童高血压应从控制体脂肪、预防肥胖做起。
Objective To clarify the correlation between childhood BMI and body composition index and blood pressure level and provide the basis for early prevention of adult diseases. Methods The height, weight, blood pressure and skinfold thickness of 910 7-year-old children in Jinan were measured. The body fat ratio (BF%) was calculated by the regression equation, and the fat tissue index (FMI) and non-fat tissue index (FFMI) were calculated. Results BMI, BF%, FMI and FFMI were positively correlated with systolic and diastolic pressures (P <0.05). The correlation between BP and FMI was higher than that of FFMI. Children with high BMI and BF% percentile had significantly higher blood pressure levels than those with low percentile (P <0.05). The detection rate of high blood pressure was obesity group> overweight group> normal group> weight loss group. Conclusion There is a significant correlation between BMI and body composition index and blood pressure level in children. Prevention of high blood pressure in children should start from the control of body fat, prevent obesity.
