Studies suggest that higher rates of excess adiposity in Black women may in part be driven by experiences of racism. Racial microaggressions, which include unintentional and subtle slights and insults, and responses to racism such as racism-related vigilance, may contribute to adiposity in this population. This study examined these understudied racism-related facets as well as interpersonal racial discrimination in relation to adiposity in a cohort of Black women with systemic lupus erythematosus. Data are from the Black Women's Experiences Living with Lupus (BeWELL) Study (2015–2017; n = 432). Linear regression was used to examine adiposity measures (body mass index [BMI], percent body fat, and waist-to-hip ratio), measured during a physical examination, in relation to self-reported measures of racial microaggressions, racism-related vigilance, and interpersonal racial discrimination. Compared with infrequent microaggressions, very frequent experiences of microaggressions were associated with 2.9 kg/m2 higher BMI (95% confidence [CI], 0.63–5.21) and 2.6% higher body fat (95% CI, 0.32–4.80) after adjusting for covariates. Racism-related vigilance, measured continuously, was positively associated with BMI (b = 0.84; 95% CI–0.08, 1.61) and percent body fat (b = 0.89; 95% CI, 0.14–1.64). Very frequent experiences of everyday discrimination were associated with a higher BMI (b = 2.70; 95% CI, 0.58–4.83) and waist-to-hip ratio (b = 0.32; 95% CI, 0.09–0.55) compared with less frequent everyday discrimination. Our results suggest that various dimensions of racism are associated with excess adiposity. Efforts to address obesity among Black women with systemic lupus erythematosus should consider these multiple aspects to decrease racial inequities in adiposity.
