Weight discrimination has adverse effects on health that include increasing the risk factors for developing type 2 diabetes. Preliminary evidence suggests a positive association between weight discrimination and diagnosed diabetes; however, it is unknown whether psychosocial resources may buffer this association. In logistic regressions stratified by gender, we examined links between weight discrimination and diabetes among a nationally representative sample of U.S. adults (the National Social Life, Health, and Aging Project; N = 2,794 adults age 50 and older in 2015-16). We also tested the extent to which trait-resilience and social support from a spouse/partner, family, and friends buffered any observed association. We adjusted for known predictors of diabetes (age, race/ethnicity, Body Mass Index) and conducted sensitivity analyses restricted to men and women with obesity. Net of covariates, in the overall sample, weight discrimination was associated with significantly greater odds of having ever had diabetes among women (OR = 2.00, 95% CI [1.15, 3.47]), but not men. Among women with obesity, weight discrimination was only significantly associated with greater odds of diabetes for those with low resilience (OR = 1.84, 95% CI [1.01, 3.35]). Among men overall, weight discrimination was associated with lower odds of diabetes for those with high family support (OR = 0.03, 95% CI [0.003, 0.25]) as well as those with high friend support (OR = 0.34, 95% CI [0.13, 0.91]); similar effects were observed in men with obesity. These novel findings evince a role for psychosocial resources in buffering associations between weight discrimination and diabetes.

体重歧视会对健康产生不利影响，包括增加患 2 型糖尿病的风险因素。初步证据表明体重歧视与诊断出的糖尿病之间存在正相关关系；然而，尚不清楚社会心理资源是否可以缓冲这种关联。在按性别分层的逻辑回归中，我们研究了具有全国代表性的美国成年人样本中体重歧视与糖尿病之间的联系（国家社会生活、健康和老龄化项目；2015-16 年N  = 2,794 名 50 岁及以上成年人）。我们还测试了配偶/伴侣、家人和朋友的特质弹性和社会支持对任何观察到的关联的缓冲程度。我们调整了已知的糖尿病预测因素（年龄、种族/民族、体重指数），并进行了仅限于肥胖男性和女性的敏感性分析。扣除协变量后，在整个样本中，体重歧视与女性患糖尿病的几率显着较高相关（OR  = 2.00，95% CI [1.15，3.47]），但与男性无关。在肥胖女性中，体重歧视仅与弹性较低的女性患糖尿病的几率较高显着相关（OR  = 1.84，95% CI [1.01，3.35]）。总体而言，在男性中，对于家庭支持度较高的男性（OR  = 0.03，95% CI [0.003，0.25]）以及朋友支持度较高的男性（OR  = 0.34，95% CI [ 0.13, 0.91]); 在肥胖男性中也观察到了类似的效果。这些新发现表明社会心理资源在缓冲体重歧视和糖尿病之间的关联方面发挥着重要作用。
