Cardiometabolic health in Asians with diabetes in the US

Abstract

Aims: Asians develop diabetes at lower levels of adiposity than people of other race/ethnicities. However, there is limited data investigating the health of US Asians with diabetes. We compared cardiovascular risk factors in US Asians to other race/ethnicities stratified by diabetes status.

Methods: Among 4645 adults in the 2011-2014 National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey of the US population, odds ratios were calculated for obesity, hypertension, and elevated low-density lipoprotein (LDL) cholesterol associated with race/ethnicity after adjustment for age, sex, income, education, smoking, alcohol consumption, and health insurance.

Results: Overall and stratified by diabetes status, non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans were significantly more likely to be obese compared to non-Hispanic Asians after adjustment. Overall and stratified by diabetes status, adjusted levels of hypertension compared to non-Hispanic Asians was generally similar for non-Hispanic whites and Mexican-Americans and generally more common among non-Hispanic blacks; among those with diagnosed diabetes, the adjusted odds ratios (95% confidence interval) were 1.48 (0.79-2.77), 2.54 (1.49-4.30), and 1.38 (0.73-2.60) for non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans, respectively. Overall and stratified by diabetes status, elevated LDL cholesterol levels were generally similar between non-Hispanic Asians and other race/ethnicities; among those with diagnosed diabetes, the adjusted odds ratios (95% confidence interval) were 0.88 (0.32-2.43), 0.58 (0.24-1.42), and 1.15 (0.29-4.58) for non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans, respectively.

Conclusions: Although non-Hispanic Asians had lower levels of adiposity compared to other race/ethnicities with diabetes, their adjusted levels of hypertension and LDL cholesterol were generally more comparable.
