Using the 2013/14 New York City Health and Nutrition Examination Survey population sample, this study compared Afro Caribbean immigrants and US-born African American New Yorkers to determine a) whether prevalence and odds of type 2 diabetes (T2DM) differed between ethnic groups; and b) whether cardiometabolic health profiles differed among those with T2DM. T2DM was defined by prior diagnosis, HbA1c≥6.5%, or fasting glucose ≥126mg/dL. Weighted logistic regression estimated odds of T2DM adjusting for BMI, waist circumference, age, sex, education, income, marital status and physical activity. T2DM prevalence in Afro Caribbeans (n=81, age (Mean±SE) 49±2y, BMI 29.2 ±0.7kg/m2) was 31%, and 21% in African Americans (n=118, age 46±2years, BMI 30.3±0.9kg/m2). Afro Caribbeans had more than three times greater odds of T2DM than African Americans [aOR=3.32 (95%CI 1.11-9.88), P=0.0313]. Compared to African Americans with T2DM (n=21, Age 60.3±3.3y, BMI 34.6±1.7kg/m2), Afro Caribbeans with T2DM (n=23, Age 57.9±2.5y, BMI 29.9±0.8kg/m2) were less likely to have obesity (33.2% vs. 74.7%) and had lower waist circumference (102±2cm vs. 114±3cm, P=0.002). Although fewer Afro Caribbeans with T2DM met HP2010 physical activity goals (42.9% vs. 75.5%, P=0.0335), their mean HDL levels tended to be higher than those of African Americans with T2DM (50.6±2.5 mg/dL vs. 42.5±3.2mg/dL, P=0.0519). Afro Caribbean immigrants in New York City have higher odds of T2DM than African Americans. Nevertheless, Afro Caribbeans with T2DM have better cardiometabolic health than African Americans with T2DM. Differences in anthropometrics, blood lipids and health behaviors illustrate important intraethnic variations which affect future risk of T2DM complications among populations of African descent.
