Abstract P019: Dietary Patterns and Abdominal Adipose Tissue Distribution: CARDIA
Accumulation of abdominal visceral adipose tissue (VAT) and intermuscular adipose tissue (IMAT) are of interest because they have been reported to be more strongly associated with insulin resistance than abdominal subcutaneous adipose tissue (SAT). The pathophysiological features of these fat depots are becoming better understood; however there is little research examining the relationship between diet and abdominal adipose tissue depots. We examined the association of two empirical dietary patterns, derived via principal components analysis, with VAT, IMAT, and SAT in middle-aged (43-55 years) black and white men and women from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a cohort of 5115 people aged 18-30 years in 1985-86 (year 0). This analysis includes 2,187 participants who were free of diabetes, did not report extreme caloric intakes at the dietary history assessment at year 20, and had abdominal imaging data via CT scan at year 25. Higher scores on the “Fruit-Veg” pattern indicated higher reported intake of vegetables, fruits, whole grains, nuts and seeds and fish. Higher scores on the “Meat” pattern indicated higher intake of refined grains, red and processed meats, fried potatoes, and sugar sweetened beverages. Multivariable least squares adjusted means for the adiposity measures by quartiles of each dietary pattern were obtained from general linear models. With an increasing Fruit-Veg dietary pattern score there were significantly lower volumes of VAT and IMAT. Alternatively, with an increasing Meat dietary pattern score there were significantly higher volumes of VAT and IMAT. SAT was not associated with either dietary pattern. The results were consistent by sex, race and age. These novel data underscore how overall dietary patterns differentially associate with specific abdominal adipose tissue depots.
