Association Between Vitamin E and Handgrip Strength in the Korean General Population in KNHANES VII (2018)

Abstract

OBJECTIVE: To investigate the association between vitamin E and handgrip strength (HGS) with multiple factors. METHODS: A total of 1,814 participants were included (822 men and 981 women) from the Korean subjects of the 7th Korea National Health and Nutrition Examination Survey in 2018. Data were analyzed using multiple logistic regression to determine the correlation between vitamin E and HGS with potential confounding factors. RESULTS: In the multiple logistic regression model, only the young age group (19-40 years) of men showed a positive relationship between vitamin E and HGS. However, in older age groups (41-80 years) of men and all age groups of women, there was no statistically significant result. After adjusting for confounding factors, young men showed higher vitamin E levels and higher HGS. Conversely, women and older age groups did not show significant results after adjusting for confounding factors. CONCLUSION: In this study, the serum vitamin E level had a positive effect on HGS in young men (<40 years). Further research is needed on this topic regarding vitamin E intake and other objective measures.
