Abstract

BACKGROUND

There is paucity of information regarding time trends of weight status in children from rapidly developing economies like India. The aim of the study was to analyse the dynamics of growth and weight transitions in a cohort of school children from India.

METHODS

A population of 25 228 children was selected using stratified random sampling method from schools in a contiguous area in Ernakulam District, Kerala, India. Weight and height were measured at two time points, one in 2003-04 and another in 2005-06. The paired data of 12 129 children aged 5-16 years were analysed for the study.

RESULTS

The mean interval between the two surveys was 2.02 +/- 0.32 years. The percentage of underweight, normal weight, overweight and obese children in the year 2003-04 were 38.4%, 56.6%, 3.7%, and 1.3% respectively. The corresponding figures in year 2005-06 were 29.9%, 63.6%, 4.8% and 1.7% respectively. Among the underweight children, 34.8% migrated to normal weight status and 0.1% migrated to overweight status. Conversion of underweight to normal weight predominated in urban area and girls. Among the normal weight children, 8.6% migrated to underweight, 4.1% migrated to overweight and 0.4% migrated to obesity. Conversion of normal weight to overweight status predominated in urban area, private schools and boys. Conversion of normal weight to underweight predominated in rural area, government schools and boys. Among the overweight children, 26.7% migrated to normal weight status, 16.4% became obese and 56.9% retained their overweight status. Of the obese children, 6.2% improved to normal weight status, 25.3% improved to overweight status and 68.5% remained as obese in 2005-06. There was significant difference in trends between socio demographic subgroups regarding conversion of underweight status to normal weight as well as normal weight status to overweight.

CONCLUSION

The study population is experiencing rapid growth and nutritional transitions characterised by a decline in the underweight population coupled with an escalation of the overweight population. The heterogeneous nature of this transition appears to be due to differences in socio demographic factors.

摘要

背景

在像印度这样快速发展的经济体中，关于儿童体重状况的时间趋势的信息很少。本研究的目的是分析印度一个学童队列的生长和体重变化动态。

方法

使用分层随机抽样方法，从印度喀拉拉邦埃纳库拉姆区的学校中抽取了 25228 名儿童作为研究对象。在 2003-04 年和 2005-06 年两个时间点测量了体重和身高。对 12129 名 5-16 岁儿童的配对数据进行了分析。

结果

两次调查之间的平均间隔为 2.02±0.32 年。2003-04 年体重不足、正常体重、超重和肥胖儿童的百分比分别为 38.4%、56.6%、3.7%和 1.3%。2005-06 年的相应数据分别为 29.9%、63.6%、4.8%和 1.7%。体重不足的儿童中，34.8%转为正常体重，0.1%转为超重。体重不足转为正常体重主要发生在城市地区和女孩中。在正常体重的儿童中，8.6%转为体重不足，4.1%转为超重，0.4%转为肥胖。正常体重转为超重主要发生在城市地区、私立学校和男孩中。正常体重转为体重不足主要发生在农村地区、公立学校和男孩中。超重的儿童中，26.7%转为正常体重，16.4%转为肥胖，56.9%仍保持超重。肥胖儿童中，6.2%转为正常体重，25.3%转为超重，68.5%仍为肥胖。社会人口亚组在体重不足向正常体重转变以及正常体重向超重转变方面的趋势存在显著差异。
