Overview

Randomized trial observes elevated hs-CRP levels in older adults with prolonged sedentary time, indicating health risks.

Key Points

  • This study aims to explore the relationship between sedentary time and high-sensitivity C-reactive protein levels in older Korean adults.
  • Analyzed data from the 2022 Korea National Health and Nutrition Examination Survey.
  • Final sample included 1,171 participants aged 65 years and older after exclusions.
  • Applied chi-square tests and multivariable logistic regression to assess associations.
  • Abnormal hs-CRP prevalence was higher in individuals not engaging in regular walking (PR, 1.24; 95% CI, 1.05 to 1.46).
  • Participants with sedentary time ≥10 hours per day exhibited higher abnormal hs-CRP rates (PR, 1.20; 95% CI, 1.02 to 1.41).
  • Prolonged sedentary time correlated with abnormal hs-CRP levels (odds ratio, 1.31; 95% CI, 1.01 to 1.71) after adjusting for covariates.
