Abstract P259: Improvements in Diet Quality Are Associated With Reduced Abdominal Adiposetissue: A Prospective Study

Objectives: Visceral adipose tissue (VAT) and abdominal subcutaneous adipose tissue (SAT) are associated with cardiometabolic diseases. The relationship between diet quality and abdominal fat accumulation, however, has not been well studied. We aimed to examine the long-term association of change in diet quality and change in abdominal adipose tissue. Methods: In 1,677 participants who attended two consecutive Framingham Heart Study examinations, we measured the volume of VAT and SAT using multi-detector computed tomography at two time-points (median interval of 6 years). The ratio of VAT/SAT was calculated to reflect the relative abundance of these two fat stores, i.e., abdominal fat distribution. We created two scores to represent overall diet quality, the Mediterranean-style diet score (MDS) and the Alternative Healthy Eating Index (AHEI) score, using food frequency questionnaires at baseline and follow-up exams. We analyzed the association between change in the dietary scores and change in VAT, SAT, a...
