ObjectiveThis study was designed to determine (a) whether the prevalence and odds of either obesity or diabetes differed in foreign-born black Africans and Caribbeans living in New York City (NYC) and (b) whether time in the United States (US) affected odds of either outcome.MethodsData were obtained from NYC Community Health Survey 2009–13 for 380 African-born blacks and 2689 Caribbean-born blacks. Weighted logistic regression estimated odds of obesity and diabetes, adjusting for age, sex, education, income, marital status, children < 18, BMI (diabetes models only), and time in the US.ResultsObesity prevalence in Africans (60.2%, male; age, 46.0 ± 13.5 years, (mean ± SD); BMI, 27.3 ± 5.6 kg/m2) was 16.7 and 30.2% in Caribbeans (39.3%, male; age, 49.7 ± 14.7 years; BMI, 28.0 ± 5.8 kg/m2). Prevalence of diabetes was 10.5% in Africans and 14.7% in Caribbeans. Africans had lower adjusted odds of obesity (aOR = 0.60 (95% CI, 0.40–0.90); P = 0.015), but there was no difference in diabetes odds between groups. Obesity odds were higher in African (aOR = 2.35 (95% CI, 1.16–4.78); P = 0.018) and Caribbean women (aOR = 2.20 (95% CI, 1.63–2.98); P < 0.001) than their male counterparts. Odds of diabetes did not differ between sexes in either group. Time in the US did not affect odds of either obesity or diabetes.ConclusionsAfricans living in NYC are less obese than Caribbeans, but odds of diabetes do not differ. Time in the US does not affect odds of either obesity or diabetes. Hence, BMI and diabetes risk profiles in blacks differ by region of origin and combining foreign-born blacks into one group masks important differences.
