BACKGROUND
Little is known about changes in overweight/obesity and central obesity status among schoolchildren from preadolescence to adolescence in Japan, where waist circumference (WC) is generally not measured in annual health examinations at elementary and junior high schools. This study examined changes of overweight/obesity and central obesity status among schoolboys and schoolgirls from preadolescence to adolescence in Japan.
METHODS
Study subjects were fourth-grade school children (9 or 10 years of age) from all four of Ina town's elementary schools in Japan. Measurement of each participant's height, weight, and WC were made at baseline and 3 years later. Childhood overweight/obesity was determined according to the age- and sex-specific body mass index cut-off points proposed by the International Obesity Task Force. Central obesity was defined as waist-to-height ratio ≥ 0.5. Kappa (κ) statistic was calculated to examine the tracking of overweight/obesity and central obesity.
RESULTS
Data from 1436 participants (boys: n = 720, girls: n = 716) were analyzed. Overweight/obesity status tracked substantially from fourth grade to seventh grade in both boys (κ = 0.614, P value < 0.001) and girls (κ = 0.619, P value < 0.001). Among participants who were overweight/obese in fourth grade, 55.2% of boys and 63.2% of girls were still overweight/obese in seventh grade. Tracking of central obesity from fourth graders to seventh graders was substantial in boys (κ = 0.651, P value < 0.001) and moderate in girls (κ = 0.544, P value < 0.001). Among participants who had central obesity in fourth grade, 54.1% of boys and 52.6% of girls still had central obesity in seventh grade.
CONCLUSIONS
The present study showed that the tracking of overweight/obesity from preadolescence to adolescence was substantial in boys and girls. Moreover, more than half of those who had central obesity in preadolescence had central obesity in adolescence. This study suggests that it is important to implement a primary prevention program for overweight/obesity and central obesity in elementary schools before fourth grade.
背景
在日本，小学和初中的年度体检通常不测腰围，因此人们对于儿童期到青春期超重/肥胖和中心性肥胖状况的变化知之甚少。本研究旨在探讨日本男、女学生从儿童期到青春期超重/肥胖和中心性肥胖状况的变化。
方法
研究对象为日本稻荷町所有四所小学的四年级学生（9 或 10 岁）。在基线和 3 年后测量每位参与者的身高、体重和腰围。根据国际肥胖工作组提出的年龄和性别特异性体质指数切点，确定儿童超重/肥胖。中心性肥胖定义为腰高比≥0.5。计算 Kappa（κ）统计量以检验超重/肥胖和中心性肥胖的可追踪性。
结果
共分析了 1436 名参与者（男生：n=720，女生：n=716）的数据。在男生（κ=0.614，P 值<0.001）和女生（κ=0.619，P 值<0.001）中，超重/肥胖状况从四年级到七年级有显著的追踪性。在四年级超重/肥胖的参与者中，55.2%的男生和 63.2%的女生在七年级仍超重/肥胖。从四年级到七年级，男生的中心性肥胖追踪性较强（κ=0.651，P 值<0.001），女生的中心性肥胖追踪性为中度（κ=0.544，P 值<0.001）。在四年级有中心性肥胖的参与者中，54.1%的男生和 52.6%的女生在七年级仍有中心性肥胖。
结论
本研究表明，男、女学生从儿童期到青春期的超重/肥胖追踪性较强。此外，超过一半在儿童期有中心性肥胖的人在青春期仍有中心性肥胖。本研究表明，在四年级之前的小学阶段，实施超重/肥胖和中心性肥胖的一级预防计划非常重要。
