Relationship Between Sedentary Lifestyle and Handgrip Strength Among Korean Workers

초록

ObjectiveThis study examined the relationship between sedentary time and handgrip strength with age-group stratification.MethodsThis study used 11,295 Korean workers. Participants were divided into two age groups: <= 39 and >= 40 years. Handgrip strength was measured, and sedentary time was self-reported. Multiple logistic and linear regression models were used to examine the association between sedentary time and handgrip strength.ResultsThose with >= 6 hours of daily sedentary time had slightly higher odds of low handgrip strength, though not significant overall (odds ratio 1.09, 95% confidence interval 0.95-1.26). However, younger adults with high sedentary time showed significantly higher odds (odds ratio 1.55, 95% confidence interval 1.13-2.12). Linear regression also indicated a stronger negative association in younger adults.ConclusionsInterventions to reduce sedentary time could help maintain muscle strength, especially in younger populations.
