South Asians, who are at a disproportionately greater risk of atherosclerotic CVD (ASCVD), represent a rapidly growing population in the USA. The relationship between dairy products, a major component of South Asian diets, and body composition - an established risk factor for ASCVD, is unclear. The aim of the present study was to examine associations between dairy intake and multiple measures of body composition (BMI, waist and hip circumference, waist:hip ratio, abdominal lean mass, subcutaneous, visceral, and intermuscular fat areas) among South Asian adults in the USA. 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/d) v. lowest (<1 serving/d) tertile of dairy intake was associated with 53 % lower odds of a waist circumference >80 cm (95 % CI 0·25, 0·89, Pfor trend<0·05). No associations were observed between dairy intake and measures of body composition. However, >3 servings of low-fat yogurt/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 with those with three servings/week. Milk and cheese 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 products, and recognises the utility of multidimensional measures of central adiposity.
南亚人患动脉粥样硬化性心血管疾病(ASCVD)的风险不成比例地更高,他们是美国人口增长最快的群体。乳制品是南亚饮食的主要组成部分,而乳制品与身体成分(ASCVD 的一个既定风险因素)之间的关系尚不清楚。本研究旨在探讨美国南亚成年人乳制品摄入量与身体成分多个指标(BMI、腰围和臀围、腰臀比、腹部去脂体重、皮下脂肪、内脏脂肪和肌间脂肪面积)之间的关系。使用美国南亚人动脉粥样硬化代谢物研究队列的现有数据进行了基线分析。在女性中,乳制品摄入量最高(>1.9 份/天)组与最低(<1 份/天)组相比,腰围>80cm 的可能性低 53%(95%CI0.25,0.89,P 趋势<0.05)。乳制品摄入量与身体成分指标之间没有观察到关联。然而,每周食用>3 份低脂酸奶与内脏脂肪面积低 9.9cm2(95%CI-19.07,-0.72,P<0.05)和肌间脂肪面积低 2.3cm2(95%CI-3.76,-0.79,P<0.05)相关。与每周食用 3 份相比,牛奶和奶酪与身体成分指标无关。这些分析表明,较高的低脂酸奶摄入量与整个样本中较低的内脏和肌间脂肪有关,而较高乳制品摄入量的女性腰围更小。我们的研究支持在饮食中加入乳制品,并认识到多维中心性肥胖测量的实用性。
