Abstract

OBJECTIVE

To create gender-specific percentile curves for percent body fat (%BF) by Bio electrical Impedance Analysis (BIA) for screening adiposity and risk of hypertension in Indian children and generate reference curves for percent fat-free mass (%FFM), muscle mass (%LM) and bone mineral content (BMC) by using bioelectrical impedance.

DESIGN

Secondary analysis of data from previous multicenter cross-sectional studies.

SETTING

Private schools from five regions of India.

PARTICIPANTS

A random sample of 3850 healthy school children (2067 boys) (5-17 yr) from private schools in five major Indian cities.

METHODS

Anthropometry, blood pressure (BP) and body composition were measured by bioelectrical impedance. Reference curves were generated by the LMS method.

MAIN OUTCOME MEASURES

%BF, %FFM, %LM, BMC and BP.

RESULTS

Median %BF increased by 6% from 5 to 13 years of age and declined (around 2%) up to 17 years in boys. In girls, %BF increased by 8% from 5 to 14 years and thereafter declined by 3%. Based upon the risk of hypertension, the new cut-offs of 75th and 85th percentile of %BF were proposed for detecting over fatness and excess fatness in children. Median %FFM was 90% at 5 yrs and decreased till 12 years, and then showed a slight increase to 84% at 17 yrs in boys. In girls, it was 86% at 5 yrs and decreased till 15 yrs, and plateaued at 71.8% at 17 yrs.

CONCLUSIONS

Reference curves for percent body fat for Indian children would be useful to screen children for health risk in clinical set up.

摘要

目的

通过生物电阻抗分析（BIA）创建特定性别的体脂百分比（%BF）百分位数曲线，用于筛查印度儿童的肥胖及高血压风险，并利用生物电阻抗生成无脂肪量百分比（%FFM）、肌肉量百分比（%LM）和骨矿物质含量（BMC）的参考曲线。

设计

对先前多中心横断面研究的数据进行二次分析。

地点

印度五个地区的私立学校。

参与者

从印度五个主要城市的私立学校中随机抽取3850名健康学童（2067名男孩）（5 - 17岁）。

方法

通过生物电阻抗测量人体测量学指标、血压（BP）和身体成分。采用LMS法生成参考曲线。

主要观察指标

%BF、%FFM、%LM、BMC和BP。

结果

男孩的%BF中位数从5岁到13岁增加了6%，到17岁下降了（约2%）。女孩的%BF从5岁到14岁增加了8%，此后下降了3%。基于高血压风险，提出了%BF第75和第85百分位数的新切点，用于检测儿童的超重和肥胖。男孩的%FFM中位数在5岁时为90%，到12岁时下降，然后在17岁时略有增加至84%。女孩的%FFM在5岁时为86%，到15岁时下降，在17岁时稳定在71.8%。
