Title: The Relationship between Ultra-processed Foods Consumption and Obesity Indicators in Iranian Adults

Abstract

Food processing changes the nature of foods and it is extending globally due to availability, affordability or palatability. Ultra-processed foods (UPFs) consumption may adversely affect weight gain. The purpose of the current study was to evaluate the association between UPFs consumption and adiposity in Iranian adults. This cross-sectional study was performed on 1459 Iranian adults (?19 years). Dietary intakes were assessed by using a validated 136-item food frequency questionnaire (FFQ) and foods were classified based on NOVA system. Overweight, obesity and abdominal obesity were defined as body mass index (BMI) ?25 and <30, ?30 and waist circumference (WC) ?91 for women and WC ?89 for men, respectively. The risk of general and abdominal obesity across the quartiles of UPFs were assessed. The associations between UPFs consumption and obesity, overweight, and abdominal obesity were evaluated by bivariate binary logistic regression. UPFs contributed to meet 20.17% of daily energy intake in the whole population. In men, higher UPFs consumption tended to be associated with higher risk of obesity (OR= 1.81, 95% CI: 0.98, 3.36). In addition, men in the top quartile of UPFs had 76% higher odds for abdominal obesity (OR = 1.76, 95% CI 1.03, 3.30). No association was found in women. Our investigation suggests a sex-specific association between UPFs and obesity. While in men, UPFs were associated with higher risk of obesity, in particular abdominal obesity, no association was found among women.  Longitudinal cohort studies are required to confirm these results.
