N2 - The purpose of this study was to test the associations between cognitive and psychological eating behavior traits and detailed measures of adiposity and body fat distribution using imaging-based methods in a cross-sectional study. Eating behavior traits (compensatory and routine restraint, external eating, and emotional eating) were assessed using the validated Weight-Related Eating Questionnaire, and measures of adiposity using anthropometry, dual energy X-ray absorptiometry (DXA), and magnetic resonance imaging (MRI). Each adiposity outcome of interest (total fat, ratio of trunk fat to periphery fat, visceral and subcutaneous fats as % of abdominal area, and % liver fat) was regressed on the four eating behaviors while adjusting for age and race/ethnicity. This study included a total of 60 postmenopausal Japanese American (n=30) and white (n=30) women (age: 60-65years, BMI: 18.8-39.6kg/m 2). Weight-related eating behavior traits did not differ by ethnicity. Higher external eating scores were associated with measures of total adiposity, including higher BMI (β=0.36, p=0.02) and DXA total fat mass (β=0.41, p=0.001), and with MRI abdominal subcutaneous fat (β=0.55, p=0.001). Higher routine restraint scores were associated with visceral adiposity (β=0.42, p=0.04). Our findings suggest that different weight-related eating behavior traits might increase not only total adiposity but also abdominal and visceral fat deposition associated with higher metabolic risks. Future research, preferably in a prospective study of men and women and including biomarkers related to psychological stress, will be needed to explore potential underlying biological mechanisms.
