Section snippets
Materials and Methods
Our analysis was a cross-sectional investigation of 150 Asian Indians living in the San Francisco Bay, CA, area who participated in the MASALA pilot study. The detailed methods have been described elsewhere.17 Briefly, this was a pilot study with a prospective cohort design, and we enrolled community-dwelling individuals from August 2006 to October 2007. Participants self-identified as Asian Indian ethnicity, were aged 45 to 84 years, and had no known cardiovascular disease. Those taking
Results and Discussion
Asian Indians in the United States in the MASALA study population were found to have two distinct dietary patterns. Using principal component analysis of completed food frequency questionnaires for all 150 participants, two dietary patterns were extracted (Table 1), which represent a total of 22.8% of the total variance in dietary pattern. The two dietary patterns observed were characterized as Western and Vegetarian. The Western dietary pattern included major nonvegetarian components besides
Conclusions
In this initial characterization of dietary patterns of Asian Indians in the United States, we found two distinct dietary patterns, both of which were associated with known metabolic risk factors. Future analyses on a larger sample population, as part of a longitudinal cohort, will provide important insights into the associations of dietary patterns in Asian Indians and incident CVD risk factors.
