N2 - Objective: The association between dietary antioxidant quality score (DAQS) and handgrip strength (HS) and handgrip endurance (HE) is still unclear. We aimed to investigate whether adherence to dietary antioxidant quality score (DAQS) is associated with handgrip strength (HS) and handgrip endurance (HE) amongst adults in Tehran. Methods: This cross-sectional study was conducted on 270 (43.7% males, mean age 37 years and 56.3% females, mean age 35 years) apparently healthy adult subjects (53.2% were married) selected from different parts of Tehran, Iran. Dietary intake was assessed using a 168-item validated food frequency questionnaire. DAQS was calculated using antioxidant-nutrient intake. Body composition was measured using a body composition analyser. Handgrip strength and endurance were measured by a digital handgrip dynamometer. Relative muscle strength was expressed as the ratio of handgrip strength by body mass index (BMI). Results: The results showed that DAQs had no significant association with HS (P =.67, adjusted R
2 =.60) and HE (P =.19, adjusted R
2 =.08) after adjusting for potential confounders. However, a significant positive association was found between selenium intake and HE even after adjusting for potential confounders (P =.01, adjusted R
2 =.10). After controlling for potential confounders no differences in the mean of HS (P =.29) and also HE (P =.61) amongst tertiles of DAQS was found. Positive linear association was found between vitamin C (P =.02, adjusted R
2 =.53) and vitamin E (P =.03, adjusted R
2 =.55) intake with relative muscle strength. Conclusion: Our results revealed that no significant association between DAQS and HE and HS. It was found that more intake of selenium was positively linked to HE. Dietary intake of vitamin C and vitamin E are associated with higher relative muscle strength. It is evident that more prospective studies are needed to confirm the veracity of our results.
