Abstract: Background: Previous epidemiologic studies have demonstrated a positive association between serum C-reactive protein (CRP) level and diabetes mellitus. However among US race-ethnicities, the putative association between CRP and diabetes mellitus in non-Hispanic Blacks is not clear. We specifically examined the association between high-sensitivity CRP level and diabetes mellitus in a representative sample of US non-Hispanic blacks. Methods: Cross-sectional study among 1,479 National Health and Nutrition Examination Survey 1999-2002 non-Hispanic black participants aged ≥20 years. Main outcome-of-interest was the presence of diabetes mellitus (fasting plasma glucose ≥126 mg/dL, non-fasting plasma glucose ≥200mg/ dL, or self-reported current use of oral hypoglycemic medication or insulin) (n=204). Results: Higher CRP levels were positively associated with diabetes mellitus, independent of smoking, waist circumference, hypertension, and other confounders. Multivariable odds ratio (OR) [95% confidence intervals (CI)] comparing elevated CRP level (>3 mg/L) to low CRP level (< 1 mg/L) was 3.12 (1.77-5.48), p-trend < 0.0001. This association persisted in separate analysis among men and women. The results were consistent in subgroup analyses by categories of age, smoking, body mass index, and hypertension status. In nonparametric models, the positive association between serum CRP and diabetes mellitus appeared to be present across the full range of CRP, without any threshold effect. Conclusions: Higher serum high-sensitivity CRP levels are positively associated with diabetes mellitus in a sample of US non-Hispanic blacks. Inflammatory processes previously shown to be related to diabetes mellitus in other race-ethnicities may be involved in non-Hispanic blacks also. © J.A.
