Poster Topical Area: Obesity

Objectives: High body mass index (BMI), and percent body fat have been reported to be associated with increased risk of cardiovascular disease. The present study examined the relationships of dietary food groups with BMI, body composition and bone mineral density.
Methods: In this cross-sectional study, a total of 83 postmenopausal women (1 to 5 years past menopause), not receiving hormone therapy were included. Dietary intake was assessed using a Block Food Frequency Questionnaire. Food groups were based on MyPlate guidelines. Body composition was measured using dual-energy X-ray absorptiometry. Partial Pearson correlations were performed using SPSS.
Results: After controlling for age, total kilocalories, ethnicity, race and physical activity, both fruits and vegetables were negatively correlated with BMI and trunk fat mass. When analyzing fat distribution, vegetables, but not fruits, were significantly associated with a lower android/gynoid ratio and lower visceral adipose tissue after controlling for the aforementioned covariants and BMI. When analyzing whole body bone mineral density (BMD), overall fruits and vegetables were not significantly associated. However, when we further divided the food groups into types of fruits and vegetables, 100% fruit juice was found to be associated with a greater BMD of the pelvis, lumbar spine and wrist. Greater consumption of whole grains was also associated with greater BMD of the ulna and radius.
Conclusion: Overall, our findings suggest that higher consumption of fruits, vegetables and whole grains could promote healthy body composition and BMD in postmenopausal women.
