【摘要】 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。

【Abstract】 Objective To validate the relationship between body mass index (BMI), body composition index and blood pressure in 7-year-old children, and to provide bases for early prevention against adult diseases. Methods A total of 910 7-year-old children participated in this study, height, weight, skinfold thickness (SFT) and blood pressure (BP) of all subjects were measured, body fat percentage (BF%) were calculated by regression equation, fat mass index (FMI) and fat-free mass index (FFMI) were calculated. Results BMI, BF%, FMI and FFMI were all significantly (P<0.05) and positively related to systolic blood pressure (SBP) and diastolic blood pressure (DBP) in both boys and girls, the correlation coefficient for BP with FMI was higher compared with FFMI. The mean values of SBP and DBP were all significantly higher(P<0.05) in high BMI and BF% percentile groups than in low percentile groups. The incidence of relative high BP were obese group>overweight group>normal-weight group>thin group. Conclusion There is a significant relationship between BMI, body composition index and blood pressure in 7-year-old children. In order to prevent hypertension among children, the priority is to control body fat and prevent obesity.

高血压是危害人类身体健康的最常见疾病，更是全球范围内的重大公共卫生问题。大量研究证明，儿童期的血压水平与成年期高血压之间存在密切关联[1-3]，高血压的防治须从儿童期开始。BMI作为评价儿童生长发育和筛查超重、肥胖的有效指标已在全世界广泛应用[4-5] ......
