摘要
目的分析群体儿童脂肪组织指数(FMI)和非脂肪组织指数(FFMI)分布对血压的影响,为成年期疾病的早期预防提供依据。方法利用2005年山东省学生体质健康调研资料,对4 321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%),并计算脂肪组织指数(FMI)和非脂肪组织指数(FFMI)。将个体的收缩压(SBP)和舒张压(DBP)转化为Z分,用标准离差法分析7～12岁青少年FMI和FFMI分布与血压水平的关联性。结果 FMI、FFMI的Z分与收缩压、舒张压的Z分存在显著正相关(P值均<0.01)。血压偏高检出率随FMI,FFMI百分位数的上升而升高,男、女生分别由FMI<P5组的3.74%和7.48%上升到FMI≥P95组的56.19%和50.94%,由FFMI<P5组的3.85%和13.21%上升到FFMI≥P95组的31.73%和36.79%。结论 FMI和FFMI分布对儿童血压水平都有明显影响,以FMI的影响最为突出。FMI和FFMI是儿童血压管理中值得应用的监测指标。
Objective To analyze the influence of fat mass index（ FMI） and fat-free mass index（FFMl） distribution on blood pressure （ BP ）, and to provide bases for early prevention against adult diseases. Methods A total of 4 321 children aged 7-12 participated in this study, their height, weight, skinfold thickness （ SFT）, systolic blood pressure （SBP） and diastolic blood pressure （ DBP ） were measured. Body fat percentage （ BF% ） were calculated by regression equation, fat mass index （ FMI） and fat-free mass index（ FFMI ） were calculated. Results The Z score of SBP and DBP were positively correlated with the Z score of FMI and FFMI in both boys and girls（ P〈0. 01 ）. The prevalence of relative high BP increased from 3.74% （boys） and 7.48% （girls） in 〈P5 FMI percentile group to 56.19% （ boys） and 50.94% （girls） in ≥P95 FMI percentile group, and increased from 3.85% （ boys） and 13.21% （girls） in 〈P5 FFMI percentile group to 31.73% （ boys） and 36.79% （girls） in ≥P95 FFMI percentile group, respectively. Conclusion FMI and FFMI distribution have obvious effects on BP level in children, especially in FMI. FMI and FFMI are valuable indices for surveillance in the BP management of Children.
