This study examined the association between major depression, obesity and body image among adolescents.
Participants were 4175 youths 11-17 years of age sampled from the community who were interviewed using the Diagnostic Interview Schedule for Children and Adolescents, Version IV, completed a self-report questionnaire, and had their weight and height measured. There were 2 measures of body image: perceived weight and body satisfaction. Obesity was associated with increased risk of depression, with no controls for covariates. However, when the association was examined in models which included weight, major depression, and body image measures and covariates, there was no association between major depression and body weight, nor between body satisfaction and major depression. Perceived overweight was strongly and independently associated with body weight (O.R. = 2.62). We found no independent association between major depression and body weight. If there is an etiologic link between major depression and body weight among adolescents, it most likely operates through processes involving components of body image. Future research should focus on the role of depression and body image in the etiology of obesity.
本研究探讨了青少年中重度抑郁症、肥胖症和身体意象之间的关系。
从社区中抽取了 4175 名 11-17 岁的青少年作为研究对象，使用儿童和青少年诊断性访谈表第 IV 版对其进行访谈，完成自我报告问卷，并测量他们的体重和身高。有两种身体意象衡量标准：自我感知体重和身体满意度。肥胖与抑郁风险增加有关，未控制协变量。然而，当在包括体重、重度抑郁症和身体意象衡量标准及协变量的模型中检查这种关联时，重度抑郁症与体重之间、身体满意度与重度抑郁症之间均无关联。自我感知超重与体重呈强独立相关（OR=2.62）。我们未发现重度抑郁症与体重之间存在独立关联。如果青少年重度抑郁症与体重之间存在病因联系，那么它最有可能通过涉及身体意象成分的过程发挥作用。未来的研究应关注抑郁和身体意象在肥胖病因中的作用。
