Background While the preclinical development of type 2 diabetes is partly explained by obesity and central adiposity, psychosocial research has shown that chronic stressors such as discrimination have health consequences as well. Purpose We investigated the extent to which the well-established effects of obesity and central adiposity on nondiabetic glycemic control (indexed by HbA(1c)) were moderated by a targeted psychosocial stressor linked to weight: perceived weight discrimination. Methods The data came from the nondiabetic subsample (n=938) of the Midlife in the United States (MIDUS II) survey. Results Body mass index (BMI), waist-to-hip ratio, and waist circumference were linked to significantly higher HbA(1c) (p<0.001). Multivariate-adjusted models showed that weight discrimination exacerbated the effects of waist-to-hip ratio on HbA(1c) (p<0.05), such that people who had higher waist-to-hip ratios and reported weight discrimination had the highest HbA(1c) levels. Conclusion Understanding how biological and psychosocial factors interact at nondiabetic levels to increase vulnerability could have important implications for public health and education strategies. Effective strategies may include targeting sources of discrimination rather than solely targeting the health behaviors and practices of overweight and obese persons.
