What is the relationship between adherence to dietary guidelines/recommendations or specific dietary patterns, assessed using reduced rank regression analysis, and measures of body weight or obesity?

Conclusion

There were a number of methodological differences among the studies examining the relationship between dietary patterns derived using reduced rank regression and body weight status. The disparate nature of these studies made it difficult to compare results, and therefore, no conclusions were drawn.

Key Findings

  • Six positive quality prospective cohort studies that used reduced rank regression to examine the relationship between dietary patterns and body weight status were included in this review. However, differences in methodologies used and populations studied prevented comparison across studies, and conclusions could not be drawn.
  • Further research is needed to examine dietary patterns and body weight status using reduced rank regression, preferably with standardized methods and response variables.
