Increased weight concern and dieting are associated with both depression and smoking among adolescents, particularly girls. This cross-sectional study examined the gender-specific role of weight concerns and dieting on the adolescent depression-smoking association.
Participants were 2051 adolescents (1056 boys and 995 girls) from seven high schools in the Netherlands who filled out questionnaires on smoking, depression, and weight constructs and of whom weight and height were measured.
Logistic regression analyses showed that for girls, but not for boys, the depression-smoking association disappeared after controlling for weight concerns and dieting.
Our findings indicate that weight concerns and dieting are important factors to consider in the depression-smoking initiation relation for girls, but not for boys. This suggests that smoking prevention programs for depressed girls might be enhanced by challenging the idea of smoking as a diet strategy and incorporating a focus on healthy weight regulation. However, before setting up a prevention trial, future prospective studies should first examine why and how weight concerns and dieting are important factors in the depression-smoking initiation relation among girls, also in conjunction with other established risk factors such as parental and peer smoking.
体重担忧增加和节食与青少年（尤其是女孩）的抑郁和吸烟行为均有关联。这项横断面研究探讨了体重担忧和节食在青少年抑郁与吸烟关联中所起的性别特异性作用。
研究对象为来自荷兰七所高中的2051名青少年（1056名男孩和995名女孩），他们填写了关于吸烟、抑郁和体重相关问题的问卷，并测量了体重和身高。
逻辑回归分析表明，对于女孩而言，在控制了体重担忧和节食因素后，抑郁与吸烟之间的关联消失了，但男孩并非如此。
我们的研究结果表明，体重担忧和节食是女孩抑郁与吸烟起始关系中需要考虑的重要因素，但男孩并非如此。这表明，通过质疑吸烟作为一种节食策略的观念，并将重点放在健康的体重调节上，针对抑郁女孩的吸烟预防项目可能会得到加强。然而，在开展预防试验之前，未来的前瞻性研究应首先探讨体重担忧和节食为何以及如何成为女孩抑郁与吸烟起始关系中的重要因素，同时还要结合其他已确定的风险因素，如父母和同伴吸烟。
