Background
This study aimed to examine the association between sitting time and handgrip strength in healthy Korean women.
Methods
A total of 5,437 participants were included from the Korea National Health and Nutrition Examination Survey 2014–2016. The overall daily sitting time was estimated using health interview surveys, and handgrip strength was assessed using a digital hand dynamometer. The relationship between sitting time and handgrip strength was calculated with a weighted analysis of covariance after adjusting for confounding variables.
Results
Participants in each age group (19–39, 40–64, ≥65 years) were divided into three categories according to sitting time: ≤5, 6–9, and ≥10 h/d. The handgrip strength tended to decrease as sitting time increased after adjusting for age, body mass index, alcohol intake, cigarette smoking, resistance exercise, aerobic physical activity, household income, education level, hypertension, diabetes mellitus, dyslipidemia, and depression in all age groups (all P<0.001).
Conclusion
We observed the inverse relationship between sitting time and handgrip strength in healthy Korean women.
