Abstract

BACKGROUND

This study aims to quantify associations between one's weight management goal and eating behaviors and physical activity among teenagers.

METHODS

Weighted logistic regressions were performed predicting healthy behaviors from weight goal separately for boys and girls while controlling for age, body mass index, socioeconomic indicators, school type, and region using data from the 2010 to 2011 Enquête québécoise sur la santé des jeunes du secondaire, a survey of a representative sample of Quebec adolescents (N = 32,040).

RESULTS

About 18%, 31%, 19%, and 34% of boys and 32%, 34%, 5%, and 25% of girls were respectively trying to lose weight, maintain their weight, gain weight, and not trying to do anything about their weight. Trying to lose weight was associated with lower likelihood of eating breakfast daily (boys: odds ratio [OR] = 0.72; 95% confidence interval [CI] = 0.61, 0.84 girls: OR = 0.61; 95% CI = 0.54, 0.70). Among girls, trying to lose weight was also associated with higher likelihood of consuming at least 5 portions of fruits and vegetables (OR = 1.20; 95% CI = 1.04, 1.37), lower likelihood of drinking sugar-sweetened beverages daily (OR = 0.77; 95% CI = 0.66, 0.90). Each weight-related goal was associated with unhealthy behaviors but most of them were also associated with adoption of healthier ones.

CONCLUSION

Having a weight related goal cannot inherently be thought of as health promoting goal.

摘要

背景

本研究旨在量化青少年的体重管理目标与饮食行为和身体活动之间的关联。

方法

使用 2010 年至 2011 年魁北克省中学青少年健康调查的数据（对代表性的魁北克青少年样本进行的调查），对男孩和女孩分别进行体重目标预测健康行为的加权逻辑回归，同时控制年龄、体重指数、社会经济指标、学校类型和地区。

结果

约 18%、31%、19%和 34%的男孩和 32%、34%、5%和 25%的女孩分别试图减肥、保持体重、增重和不试图改变体重。试图减肥与较低的每日吃早餐的可能性相关（男孩：比值比[OR] = 0.72；95%置信区间[CI] = 0.61, 0.84；女孩：OR = 0.61；95% CI = 0.54, 0.70）。在女孩中，试图减肥也与食用至少 5 份水果和蔬菜的可能性增加相关（OR = 1.20；95% CI = 1.04, 1.37），与每天饮用含糖饮料的可能性降低相关（OR = 0.77；95% CI = 0.66, 0.90）。每个与体重相关的目标都与不健康行为相关，但大多数也与更健康的行为相关。
