What is the relationship between adherence to dietary guidelines/recommendations or specific dietary patterns, assessed using reduced rank regression analysis, and risk of type 2 diabetes?
ConclusionThere is insufficient evidence, due to a small number of studies, to examine the relationship between dietary patterns derived using reduced rank regression and risk of type 2 diabetes. The differences in the methods used and populations studied made it difficult to compare results, and therefore no conclusions were drawn.
GradeIV – Not Assignable
The three positive quality prospective cohort studies included in this review used reduced rank regression (see appendix A) analysis to examine the relationship between dietary patterns and the risk of type 2 diabetes (T2D). Comparison across studies was limited by the small number of studies, differences in methodology, and in the populations studied. Therefore, no conclusions were drawn.
More research using reduced rank regression analyses should be conducted to investigate the relationship between dietary patterns and type 2 diabetes, particularly among U.S.-based populations, and including both intermediate outcomes (glucose intolerance, insulin resistance), as well as incidence of disease. Additionally, standardization in methodology, such as response variables and food groupings used, are also needed.
