Examining Dietary Patterns in Relation to Chronic Disease: Matching Measures and Methods to Questions of Interest
In this issue of Circulation, Shikany and colleagues add to the growing body of literature on dietary patterns and their relation to health outcomes.1 The purpose of their paper was to test the hypothesis that dietary patterns extracted through factor analysis are associated with risk of acute coronary heart disease (CHD) in the Reasons for Geographic and Racial Differences in Stroke Study. The authors note that studies examining associations between dietary patterns and CHD in samples with sociodemographic and regional diversity are lacking. Understanding the drivers of health disparities is critically important, and the topic of dietary patterns is of increasing interest, as noted by the most recent Dietary Guidelines Advisory Committee Report, "...because the totality of diet...may have synergistic and cumulative effects on health and disease." 2
