Abstract

OBJECTIVE: This study used a large sample size of black and white patients with type 2 diabetes to investigate the influence of perceived racial discrimination on biologic measures (glycemic control, blood pressure, and LDL cholesterol), the mental component of quality of life (MCS), and health behaviors known to improve diabetes outcomes.

METHODS: 602 patients were recruited from two adult primary care clinics in the southeastern United States. Linear regression models were used to assess the associations between perceived racial discrimination, self-care, clinical outcomes, MCS, adjusting for relevant covariates. Race-stratified models were conducted to examine differential associations by race.

RESULTS: The mean age was 61 years, with 64.9 % non-Hispanic black, and 41.6 % earning less than $20,000 annually. Perceived discrimination was significantly negatively associated with MCS (β = -0.56, 95 % CI -0.90, 0.23), general diet (β = -0.37, CI -0.65, -0.08), and specific diet (β = -0.25, CI -0.47, -0.03). In African Americans, perceived discrimination was significantly associated with higher systolic blood pressure (β = 10.17, CI 1.13, -19.22). In Whites, perceived discrimination was significantly associated with lower MCS (β = -0.51, CI -0.89, -0.14), general diet (β = -0.40, CI -0.69, -0.99), specific diet (β = -0.25, CI -0.47, -0.03), and blood glucose testing (β = -0.43, CI -0.80, -0.06).

CONCLUSIONS: While no association was found with biologic measures, perceived discrimination was associated with health behaviors and the MCS. In addition, results showed a difference in influence of perceived discrimination by race.
