Abstract:
Our objective was to estimate the prevalence of diabetes and pre-diabetes and the risk associated with BMI above the Asian cut-point of 23 in 4 Asian American communities. In a convenience sample of 981 Chinese, Hmong, Korean, and Vietnamese Americans in Sacramento County, California we measured hemoglobin A1c (HbAlc), height, weight, and waist circumference. Diabetes was defined as self-reported diabetes diagnosis or HbA1c aeyen 6.5 %, and pre-diabetes as HbAlc 5.7-6.4 % with no diabetes diagnosis. We computed age-standardized prevalence of diabetes, pre-diabetes, and BMI and waist circumference above standard and Asian cut-points, and developed multivariable models of the association of diabetes and pre-diabetes with BMI and waist circumference. The 4 ethnic groups differed substantially with respect to diabetes prevalence, BMI, and waist circumference. Hmong had the highest prevalence of diabetes (15.0 %, 95 % confidence interval [CI] 10.7-19.4 %). Diabetes and pre-diabetes were associated with BMI aeyen 25 (diabetes: odds ratio [OR] 3.4, 95 % CI 2.1-5.7; pre-diabetes: OR 4.0, 95 % CI 2.7-5.8) or between 23 and 25 (diabetes: OR 1.8, 95 % CI 1.0-3.1; pre-diabetes: OR 1.6, 95 % CI 1.0-2.4). When waist circumference was added to the model, BMI effects were attenuated, and waist circumference aeyen40 inches (men) or aeyen35 inches (women) was associated with increased risk of diabetes (OR 3.2, 95 % CI 1.6-6.2) and pre-diabetes (OR 1.7, 95 % CI 1.0-2.9). Our findings support the use of a BMI cut-point of 23 and the importance of central adiposity as a risk factor for diabetes in Asians. Diabetes risk reduction interventions for Asians are essential.
