Relationship between Sleep Time and Hand Grip Strength on Weekday and Weekend

ABSTRACT

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 metabolic 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 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 duration; 1.4, 1.4, and 2.0 for those ≥61 years with 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, 8 hours weekend sleep duration in younger men and women.
