Abstract

Objective

The Mediterranean diet is associated with lower risks for type 2 diabetes (T2D) and cardiovascular disease in certain populations, although data among diverse groups are limited. This study evaluated cross-sectional and prospective associations between a novel South Asian Mediterranean-style (SAM) diet and cardiometabolic risk among US South Asian individuals.

Methods

The study included 891 participants at baseline in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study. Culturally relevant foods were grouped into nine categories to construct the SAM score. The study examined associations of this score with cardiometabolic risk factors and incident T2D.

Results

At baseline, higher adherence to the SAM diet was associated with lower glycated hemoglobin (−0.43% ± 0.15% per 1-unit increase in SAM score; p = 0.004) and lower pericardial fat volume (−1.22 ± 0.55 cm³; p = 0.03), as well as a lower likelihood of obesity (odds ratio [OR]: 0.88, 95% CI: 0.79–0.98) and fatty liver (OR: 0.82, 95% CI: 0.68–0.98). Over the follow-up (~5 years), 45 participants developed T2D; each 1-unit increase in SAM score was associated with a 25% lower odds of incident T2D (OR: 0.75, 95% CI: 0.59–0.95).

Conclusions

A greater intake of a SAM diet is associated with favorable adiposity measures and a lower likelihood of incident T2D.

南亚地中海式饮食与有利的肥胖措施和较低的糖尿病风险相关:MASALA队列

在某些人群中，地中海饮食与2型糖尿病(T2D)和心血管疾病的风险较低有关，尽管不同群体的数据有限。本研究评估了新型南亚地中海式(SAM)饮食与美国南亚个体心脏代谢风险之间的横断面和前瞻性关联。方法:研究纳入了891名美国南亚人动脉粥样硬化介质(MASALA)研究的基线参与者。与文化相关的食物被分为九类来构建SAM评分。该研究检查了该评分与心脏代谢危险因素和T2D事件的关系。结果在基线时，较高的SAM饮食依从性与较低的糖化血红蛋白相关(SAM评分每增加1个单位- 0.43%±0.15%;P = 0.004)，心包脂肪体积降低(- 1.22±0.55 cm3;p = 0.03)，肥胖(比值比[OR]: 0.88, 95% CI: 0.79-0.98)和脂肪肝(OR: 0.82, 95% CI: 0.68-0.98)的可能性也较低。在随访(~5年)中，45名参与者发展为T2D;SAM评分每增加1个单位，发生T2D的几率降低25% (OR: 0.75, 95% CI: 0.59-0.95)。结论:摄入较多的SAM饮食与有利的肥胖措施和较低的T2D发生可能性相关。
