Evaluation of the Relationship Between Meal-Based Dietary Anti-Oxidant Quality Score with Obesity in Apparently Healthy Adults Attended to Health Care Centers in Tehran.

Abstract

Background: Studying the dietary antioxidant quality (DAQ) score as a modifiable factor to lessen the negative effects of obesity on health is vital due to the rising global trend of obesity. Therefore, this study aimed to determine how adult obesity and meal-based DAQ scores correlate.

Materials and methods: A cross-sectional study including 850 men and women in Tehran was conducted. Three 24-hour dietary recalls were used to evaluate dietary consumption. Based on the design of DAQs, the meal-based DAQ score was evaluated. Higher scores indicate better DAQ. The overall DAQ score varied from 0 to 5. To investigate the relationship between DAQs and obesity in each meal, logistic regression analysis was utilized.

Results: There was no correlation between a higher breakfast DAQ score and being overweight or obese (for overweight: OR = 0.69; 95% CI: 0.38-1.24/for obesity: OR = 0.65; CI 95%: 0.31-1.37). In the basic model, a higher lunch DAQ score was inversely related to probabilities of being overweight (OR: 0.62; 95% CI: 0.39-0.99) Such a connection remained significant after relevant confounders were considered (OR: 0.48; 95% CI: 0.27-0.84). In both the raw and fully adjusted models, there was no discernible correlation between the meal DAQ score and overweight or obesity.

Conclusion: We discovered that a higher DAQ score for lunch was substantially associated with a lower risk of being overweight but not obese. To verify our findings, additional prospective research in various populations is required.
