Abstract:

目的探讨儿童体成分指数与血压水平的相关性。方法对4326名7～12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％)，用公式计算脂肪组织指数(FMI)=BF％×体重／身高²和非脂肪组织指数(FFMI)=(体重一BF％×体莺)／身高2。结果 FMI、FFMI与收缩压(SBP)和舒张压(DBP)呈一定程度正相关，7～12岁儿童FMI与SBP的相关系数为0.432-0.531(男生)、0.413～0.485(女生)，与DBP的相关系数为0.316～0.450(男生)、 0.345～0.421(女生)。FFMI与SBP的相关系数为0.214～0.366(男生)、0.108～0.383(女生)；与 DBP的相关系数为0.090～0.250(男生)、0.063～0.214(女生)。血压与FMI的相关性高于FFMI。血压偏高儿童的体成分指数显著高于正常儿童，以FMI差距最大。结论预防儿童高血压应从控制体脂肪、预防肥胖做起。

English Abstract:

Objective To explore the relationship between body composition index and blood pressure of children，and to provide bases for early prevention against adult diseases.Methods A total of 4326 children aged 7一l 2 participated in this study，with height.weight，skinfold thickness (SFT)and blood pressure(BP)of all subjects measured.Body fat percentage(BF％)were calculated by regression equation。fat mass index(FMI)and fat-free mass index(FFMI)were calculated according to following expressions：FMI(kg／m²)=BF％×weight／height² and FFMI(kg／m²)= (weight-BF％×weight)／height².Results Systolic blood pressure(SBP)and diastolic blood pressure(DBP)were positively correlated with FMI and FFMI in both boys and girls.Correlation coefficients between SBP.DBP and FMl were 0.432一O.53 1.O.3 l 6-0.450 for boys.and O.413-0.485.0.345-0.42l for girls respectively and the correlation coefficients between SBP.DBP and FFMl were 0.214-0.366.0.090-0.250 for boys.and 0.108-0.383.0.063-0.214 for girls respectively.The coefficient between BP and FMl were larger than those between BP and FFMI.The mean values of FMI and FFMI of children with high BP were significantly higher than those normal children.especially showed in FMI.Conclusion In order to prevent hypertension among children， priority should be comcentrated on controlling bodv fat and preventing obesity.
