Abstract
AIMS: It is unclear how the prevalence of diabetes in Asian Indians in urban India compares to that of race/ethnic groups in the US that may have different underlying susceptibilities. Therefore we examined ethnic variations in the prevalence of type 2 diabetes, iIFG, iIGT, IFG+IGT, and the associated risk factors in Asian Indians in Chennai, India, and Whites, Blacks, and Hispanics in the United States.
METHODS: Cross-sectional analyses, using representative samples of 4,867 Asian Indians aged 20-74 years from Chennai, India in the Centre for Cardiometabolic Risk Reduction in
RESULTS: The age-adjusted prevalence of type 2 diabetes was highest in Asian Indians (men; 29.0, 95% CI: 25.9, 31.0), women; (30.6, 95% CI, 27.5, 33.9)) and lowest in Caucasians (men; 12.2, 95% CI, 10.3, 14.4), women; 9.5 (7.9, 11.5). Asian Indians had the lowest prediabetes prevalence (men; 19.0 (17.2, 20.8); women 27.2, 95% CI, 22.8, 32.1)) and Caucasians had the highest (men; 46.5 (43.5, 49.6), women; 34.4, 95% CI, 31.7, 37.3). However, there were differences in prediabetes prevalence by gender and prediabetes state. The inclusion of HOMA-β in standardized polytomous logistic regression models resulted in a greater odds of diabetes in Blacks and Hispanics compared to Asian Indians.
CONCLUSIONS: The high prevalence of diabetes in Asian Indians may be due to innate susceptibilities for β-cell dysfunction in this high risk population.
