Abstract

South Asians, who are at a disproportionately greater risk of atherosclerotic cardiovascular disease (ASCVD), represent a rapidly growing population in the United States (U.S.). The relationship between dairy, a major component of South Asian diets, and body composition- A n established risk factor for ASCVD, is unclear. The aim of the present study was to examine the associations between dairy intake and multiple measures of body composition (body mass index, waist and hip circumference, waist-to-hip ratio, abdominal lean mass, subcutaneous, visceral, and intermuscular fat areas) among South Asian adults in the U.S. A baseline analysis was conducted using existing data from the Mediators of Atherosclerosis in South Asians Living in America cohort. In women, the highest (>1.9 servings/day) vs. lowest (<1 serving/day) tertile of dairy intake was associated with a 53% lower odds of a waist circumference >80 cm (95%CI:0.25,0.89,ptrend<0.05). No associations were observed between dairy intake and measures of body composition. However, greater than 3 servings of low-fat yogurt per week was associated with a 9.9 cm2 lower visceral fat area (95%CI:-19.07,-0.72,p<0.05) and 2.3 cm2 lower intermuscular fat area (95%CI:-3.76,-0.79,p<0.05) as compared to those with ≤3 servings per week. Milk and cheese (whole/low-fat) were not associated with body composition measures. These analyses suggest that higher consumption of low-fat yogurt is associated with lower visceral and intermuscular fat in the whole sample, and women with higher dairy intake have lower waist circumference. Our study supports dietary incorporation of dairy, and also recognizes the utility of multi-dimensional measures of central adiposity.
