N2 - Background and Objective: Work discrimination is an important public health problem with consequences for health. This study examined the effect of chronic work discrimination on 4-year changes in HbA1c, as a reflection of glucose control and type 2 diabetes risk in older workers and assessed whether allostatic load (AL) affected the strength of this association. Research Design and Methods: We used Health and Retirement Study data (2010-2016, n = 3,246). Conditional change multinomial logistic regression examined the association between chronic work discrimination, high AL (4 or more out of 8 high-risk biomarkers), and HbA1c, while accounting for relevant covariates. Results: Black participants had the highest rates of baseline (22.7%) and follow-up (28%) HbA1c levels, AL (38%), and chronic work discrimination (39%; p < .01). Severe chronic work discrimination was associated with elevated HbA1c (relative risk ratio [RRR] = 1.61, 95% confidence interval [CI] = 1.07, 2.43). AL was associated with elevated HbA1c (RRR = 1.49, 95% CI = 1.04, 2.14). Relative to White participants, Hispanic (RRR = 1.52, 95% CI = 1.07, 2.16, RRR = 1.81, 95% CI = 1.051, 3.12), and Black (RRR = 2.42, 95% CI = 1.82, 3.23; RRR = 3.00, 95% CI = 1.97, 4.56) participants had an increased risk of intermediate and elevated HbA1c, respectively. Among those with long job tenure (≥5 years), both moderate (RRR = 1.81, 95% CI = 1.11, 2.96) and severe (RRR = 1.90, 95% CI = 1.15, 3.12) chronic work discrimination was associated with elevated HbA1c. Discussion and Implications: Chronic work discrimination was associated with HbA1c; however, no moderating effects of AL were observed. Findings underscore a need for organizational and public health measures to establish strong anti-discrimination laws in the workplace to improve the work environment of older workers and reduce diabetes risk.
