目的：肥胖已被证明会增加抑郁症的风险。肥胖者因体重而受到歧视。在3项研究中，我们首次测试了经历（感知）基于体重的歧视是否解释了为什么肥胖与抑郁症状增加的前瞻性相关。方法：数据来自3项研究，包括英国老龄化纵向研究（2008/2009-2012/2013），健康与退休研究（2006/2008-2010/2012），美国中年（1995/1996-2004/2005），被用来检查肥胖，感知体重歧视和抑郁症状之间的关联，286美国成年人了结果：在所有3项研究中，II级和III级肥胖与基线至随访期间抑郁症状的增加可靠相关。在所有3项研究中，感知的基于体重的歧视预测了抑郁症状随时间的增加，并介导了肥胖和抑郁症状之间的前瞻性关联。II级和III级肥胖者更有可能报告经历基于体重的歧视，这解释了3项研究中平均约31%的肥胖相关抑郁症状增加。结论：在美国和英国。根据2005年的样本，肥胖（使用体重指数定义）和成年期抑郁症状增加之间的前瞻性关联可能部分由感知的体重歧视解释。
Objective: Obesity has been shown to increase risk of depression. Persons with obesity experience discrimination because of their body weight. Across 3 studies, we tested for the first time whether experiencing (perceived) weight-based discrimination explains why obesity is prospectively associated with increases in depressive symptoms. Method: Data from 3 studies, including the English Longitudinal Study of Ageing (2008/2009–2012/2013), the Health and Retirement Study (2006/2008–2010/2012), and Midlife in the United States (1995/1996–2004/2005), were used to examine associations between obesity, perceived weight discrimination, and depressive symptoms among 20,286 U.S. and U.K. adults. Results: Across all 3 studies, Class II and III obesity were reliably associated with increases in depressive symptoms from baseline to follow-up. Perceived weight-based discrimination predicted increases in depressive symptoms over time and mediated the prospective association between obesity and depressive symptoms in all 3 studies. Persons with Class II and III obesity were more likely to report experiencing weight-based discrimination, and this explained approximately 31% of the obesity-related increase in depressive symptoms on average across the 3 studies. Conclusion: In U.S. and U.K. samples, the prospective association between obesity (defined using body mass index) and increases in depressive symptoms in adulthood may in part be explained by perceived weight discrimination.
