Objective: Using Jackson Heart Study data, we examined the associations of perceived discrimination with metabolic syndrome (MetS) severity among AA adults at baseline and over 8-year follow-up.
Methods: Daily discrimination, lifetime discrimination, and discrimination burden were reported by 3,870 participants aged 21 to 95 years (mean age 53.8±13.0; 63.1% female). Each discrimination variable was classified into tertiles (low, medium, high). After adjustment for demographics and MetS risk factors (i.e., nutrition, physical activity, smoking status, and alcohol consumption), associations of discrimination variables were examined with a sex- and race/ethnicity-specific MetS severity Z-score.
Results: Independent of lifestyle and demographic factors, perceived daily discrimination was significantly associated with medium and high levels (p=0.024 and p=0.004, respectively). Medium (p=0.0505) and high (p=0.0574) reported levels of lifetime discrimination approached a significant association with MetS severity. Only medium levels of perceived lifetime discrimination were associated with a change in MetS severity over time (p=0.0209). There was no significant association between discrimination burden and MetS severity in any model.
Conclusions: Our results suggest discrimination is a salient psychosocial risk factor for the severity of MetS among AA.
