Background: This study aimed to evaluate the association between sleep duration and handgrip strength (HGS) with the consideration for sex and age groups.
Methods: Among 10,783 individuals of the Korea National Health and Nutrition Examination Survey 2016-2017, the associations of weekend and weekdays sleep duration with HGS were analyzed using logistic regression analysis after adjusting for income, education, smoking·alcohol use, weight status, presence of met- abolic syndrome and chronic illness according to sex and age (19- 40, 41-60, ≥ 61).
Results: With respect to the weekdays sleep duration, the odds ratios for low HGS in men and women aged ≥ 61 years with >8 hours sleep duration were 1.8 and 1.7, while the odds ratio (OR) was 1.4 in women aged ≥ 61 years with <6 hours compared to reference group. With respect to the weekend sleep duration, the ORs for low HGS in men 41-60 years with 7-8 hours or >8 hours sleep were 2.7 and 4.9, while the OR in men ≥ 61 years with >8 hours sleep was 2.1. In women, the OR was 1.5 for those 19-40 years with >8 hours sleep dura- tion; 1.4, 1.4, and 2.0 for those ≥ 61 years with <6 hours sleep, 7-8 hours sleep, and >8 hours sleep.
Conclusions: Higher risk for low HGS was associated with >8 hours sleep duration in weekdays and weekend in older men and women, <6 hours sleep duration in weekdays or weekend in older women, and >8 hours weekend sleep duration in younger men and women.
