饮食模式有助于心血管疾病（CVD）的风险。亚洲印第安人有。比许多其他种族/族裔群体发病更早、更严重和更普遍的CVD。我们的目的是描述生活在美国的亚洲印度人的饮食模式，并检查与心脏代谢危险因素的关联。2006年8月至2007年10月期间居住在加利福尼亚州旧金山弗朗西斯科湾地区的150名年龄在45至84岁、无已知CVD的亚洲印度人入组了生活在美国的南亚人的代谢综合征和动脉粥样硬化研究。所有参与者都获得了在亚洲印度人中验证的食物频率问卷、空腹血液样本和计算机断层扫描。主成分分析与方差最大旋转被用来确定流行的饮食模式。对饮食模式和代谢因素之间的关联进行线性回归分析，首先调整年龄和性别，然后再调整BMI、收入、教育、代谢当量、运动时间、饮酒和吸烟。两种不同的饮食模式被确定，我们称之为“西方”和“素食”。“与西方饮食相比，素食饮食与较低的稳态评估模型-胰岛素抵抗（-1.12 mmol/LxmU/L; P=0.05）和较低的高密度脂蛋白胆固醇（-4.77 mg/dL; P=0.09）相关。鉴于西方和素食饮食模式都与不良代谢变化有关，健康的饮食选择可能有助于亚洲印度人改善心血管疾病的风险因素。
Dietary patterns contribute to cardiovascular disease (CVD) risk. Asian Indian's have. earlier onset, more severe, and more prevalent CVD than many other racial/ethnic groups. We aimed to characterize dietary patterns in Asian Indians living in the United States and examine associations with cardiometabolic risk factors. One hundred fifty Asian Indians, aged 45 to 84 years, without known CVD, living in the San Francisco Bay, CA, area between August 2006 and October 2007 were enrolled into the Metabolic syndrome and Atherosclerosis in South Asians Living in America study. A food frequency questionnaire validated in Asian Indians, fasting blood samples, and computed tomography scans were obtained for all participants. Principal component analysis with varimax rotation was used to determine prevalent dietary patterns. Linear regression analyses were performed for associations between dietary patterns and metabolic factors, adjusting initially for age and sex, then additionally for BMI, income, education, metabolic equivalent of task-minutes of exercise, alcohol consumption, and smoking. Two distinct dietary patterns were identified that we termed "Western," and "Vegetarian." Compared with the Western diet, the Vegetarian diet was associated with lower homeostasis model of assessment-insulin resistance (-1.12 mmol/LxmU/L; P=0.05) and lower high-density lipoprotein cholesterol (-4.77 mg/dL; P=0.09). Given that the Western and Vegetarian dietary patterns were each associated with adverse metabolic changes, healthful diet choices may help Asian Indians improve risk factors for CVD.
