Relationship between Dietary Total Antioxidant Capacity and Risk of Obesity and Overweight among a Group of Iranian Military Staffs

Abstract

Background:Earlier studies have been conducted on the associations of individual antioxidants with risk of obesity in different groups of patients; however, no study has been conducted on the association of dietary total antioxidants capacity (TAC) with risk of obesity in military staffs.Materials and Methods:This cross-sectional study was conducted on a population of military staffs in Isfahan, Iran. Complete data were available for 170 men military staffs. A self-administered questionnaire collecting data on demographic traits was given to participants. A validated Willett-format dish-based 168-item semi-quantitative food frequency questionnaire was used to measure dietary intake.Results:Overall, 40.4 of participants had overweight and 10.2 had obesity. Participants with the highest dietary total antioxidant capacity (TAC) had 25 higher risk of overweight than those in the lowest category, but the association was nonsignificant (odds ratio, OR: 1.25, 95 confidence interval, CI: 0.58, 2.66, Ptrend = 0.56). After adjustment for the possible confounders, the association remained nonsignificant (OR: 0.59, 95 CI: 0.16, 2.07, Ptrend = 0.41). In addition, no significant relationship was seen between dietary TAC and risk of obesity in the crude model (OR: 0.68, 95 CI: 0.20, 2.30, Ptrend = 0.53) and after adjustments (OR: 0.89, 95 CI: 0.08, 8.91, Ptrend = 0.82).Conclusion:We found no significant association between dietary TAC and risk of overweight, obesity, and abdominal obesity in Iranian army staffs. The risk of overweight, obesity, and abdominal obesity in Iranian army staffs was not significantly associated with dietary TAC. Further studies using different anthropometric measures are required to shed light on this issue.
