Abstract

BACKGROUND

Studies indicate that weight perception among adolescents is associated with weight control, certain risky behaviors, and mental health.

PURPOSE

The aims of this study were to explore the perception of body size among overweight adolescents and to determine whether they consider it necessary to adjust weight and adopt healthier life habits and associated health-promoting behaviors.

METHODS

A cross-sectional descriptive design was used to investigate a convenience sample of 217 overweight adolescents(mean body mass index = 27.01 kg/m2, SD = 3.44 kg/m2) in the Taoyuan County, Taiwan, between January 2005 and December 2006.

RESULTS

Results showed that 93% (202/217) of participants perceived a need to adjust weight. However, only 59.9% (121/202) took weight-reducing action. Of those who took action, only 32.2% (39/121) employed "healthy" methods (including healthier eating and greater exercise), with 28.1% (34/121) focusing on exercise only and 20.7% concentrating on altering eating behavior only. The remaining 19% chose alternative strategies, such as restricting their diet, skipping breakfast, or taking herbs. Adolescents who perceived it necessary to adjust their weight and take appropriate action had higher scores on health promotion practices than those of adolescents who did not.

CONCLUSIONS

This study provides valuable insight, showing that overweight adolescents, although eager to lose weight, are likely to choose unhealthy methods. School and family health promotion counseling may help encourage overweight adolescents to adopt more healthy habits.

摘要

背景

研究表明，青少年的体重感知与体重控制、某些危险行为和心理健康有关。

目的

本研究旨在探讨超重青少年对身体大小的感知，并确定他们是否认为有必要调整体重，采取更健康的生活习惯和相关的促进健康行为。

方法

采用横断面描述性设计，于 2005 年 1 月至 2006 年 12 月期间在台湾桃园县调查了一个方便样本的 217 名超重青少年（平均体质指数=27.01kg/m2，SD=3.44kg/m2）。

结果

结果表明，93%（202/217）的参与者认为需要调整体重。然而，只有 59.9%（121/202）采取了减肥行动。在采取行动的人中，只有 32.2%（39/121）采用了“健康”方法（包括更健康的饮食和更多的运动），28.1%（34/121）仅关注运动，20.7%仅关注改变饮食行为。其余 19%选择了替代策略，如限制饮食、不吃早餐或服用草药。认为有必要调整体重并采取适当行动的青少年的健康促进实践得分高于那些没有这样做的青少年。
