Adolescent weight and depressive symptoms are serious population health concerns in their own right and as they relate to each other. This study asks whether relationships between weight and depressive symptoms vary by sex and race/ethnicity because both shape experiences of weight and psychological distress.
Results are based on multivariate analyses of National Longitudinal Study of Adolescent Health (Add Health) data.
There are no associations between adolescent girls' weight and depressive symptoms, but these associations vary considerably among boys. Underweight is associated with depressive symptoms among all boys and subpopulations of White and Hispanic boys. Among Hispanic boys, those who are overweight (versus normal weight) have a probability of reporting depressive symptoms. Finally, among normal weight boys, Hispanics and Blacks are more likely to report depressive symptoms than Whites.
Findings are a reminder that understanding population health issues sometimes requires a focus on subpopulations, not simply the population as a whole.
青少年体重和抑郁症状本身就是严重的人口健康问题，而且它们之间相互关联。本研究探讨体重与抑郁症状之间的关系是否因性别和种族/族裔而异，因为这两者都会影响体重体验和心理困扰。
结果基于对青少年健康全国纵向研究（Add Health）数据的多变量分析。
青少年女孩的体重与抑郁症状之间没有关联，但在男孩中，这些关联差异很大。所有男孩以及白人男孩和西班牙裔男孩亚群体中，体重过轻与抑郁症状有关。在西班牙裔男孩中，超重（相对于正常体重）的男孩报告有抑郁症状的概率更高。最后，在体重正常的男孩中，西班牙裔和黑人比白人更有可能报告有抑郁症状。
研究结果提醒我们，理解人口健康问题有时需要关注亚群体，而不仅仅是整个群体。
