Abstract

OBJECTIVES

To examine the relationships between body image, body satisfaction and dieting behavior in the context of pubertal changes in Japanese preadolescents.

METHODS

A cross-sectional study of dieting behavior among 5,244 preadolescents (2,452 boys and 2,792 girls aged 12-13) born in Toyama prefecture.

RESULTS

The percentages of those who perceived themselves fat, wanted to be thinner, and had tried dieting, which increased with body mass index (BMI), were significantly higher in girls than in boys (34.2% vs. 20.0%, 58.0% vs. 26.0%, and 17.3% vs. 5.7%, respectively). Independent of sex and BMI, those who wanted to be thinner and those who had tried dieting were more frequently observed in those who perceived themselves fat, and those who had tried dieting were more frequently observed in those who wanted to be thinner. Pubertal changes were significantly associated with dieting behavior, but their relationships to body image and body satisfaction differed between sexes; for boys, those who perceived themselves fat were more frequently observed in those without pubertal changes; whereas for girls, those who wanted to be thinner were more frequently observed in those with pubertal changes.

CONCLUSIONS

Dieting behavior of Japanese preadolescents was associated with whether they perceived themselves fat and wanted to be thinner, sometimes independent of whether they were actually overweight. Pubertal changes might induce a positive perspective of growing fat among boys and a desire to be thinner among girls, with the consequence that dieting behavior would be reinforced in those with pubertal changes.

摘要

目的

在日本青春期前儿童青春期变化的背景下，研究体像、体满意度和节食行为之间的关系。

方法

对富山县 5244 名青春期前儿童（男 2452 名，女 2792 名，年龄 12-13 岁）的节食行为进行横断面研究。

结果

与男孩相比，女孩中认为自己胖、想变瘦和尝试节食的比例随着体重指数（BMI）的增加而显著升高（分别为 34.2%比 20.0%、58.0%比 26.0%和 17.3%比 5.7%）。独立于性别和 BMI，那些认为自己胖的人更频繁地想要变瘦，那些尝试过节食的人更频繁地想要变瘦，那些尝试过节食的人更频繁地想要变瘦。青春期变化与节食行为显著相关，但与体像和体满意度的关系在性别之间存在差异；对于男孩，那些没有青春期变化的人更容易认为自己胖；而对于女孩，那些想要变瘦的人更容易有青春期变化。
