Abstract

The purpose of this study was to investigate the prevalence of sedentary behavior among patients with knee osteoarthritis and its associated factors, providing a reference for developing future intervention programs to improve sedentary behaviour in this population. A total of 311 patients with knee osteoarthritis admitted to a tertiary hospital in Guizhou Province were enrolled in the study. Assessments were conducted using the following instruments: a sociodemographic questionnaire, Tampa Kinesiophobia Scale, Knee Function Scale, Social Support Scale, Fatigue Scale, Hospital Anxiety and Depression Scale, and Pittsburgh Sleep Quality Index. Results showed that the median daily sedentary time of the total sample was 5 h (range: 4-7 h), with 140 patients (45.0%) exhibiting ≥ 6 h/day of sedentary time. Logistic regression analysis indicated that female (OR = 0.126, 95% CI 0.033-0.480, P = 0.006), live alone (OR = 0.195, 95% CI 0.042-0.944, P = 0.042), town (OR = 6.502, 95% CI 1.678-25.197, P = 0.007), city (OR=9.652, 95% CI 1.591-58.572, P=0.014), NRS≥ 4 (OR = 4.624, 95% CI 1.471-14.539, P = 0.009), social support (OR = 0.070, 95% CI 0.024-0.208, P < 0.001), anxiety (OR = 4.615, 95% CI 1.523-13.986, P = 0.007), depression (OR = 5.693, 95% CI 1.824-17.776, P = 0.003), fatigue (OR = 5.767, 95% CI 1.907-17.442, P = 0.002), KSS (OR = 0.183, 95% CI 0.045-0.743, P = 0.018), and other factors significantly increased the incidence of sedentary behaviour among patients with knee osteoarthritis. The study revealed that sedentary behaviour is substantial proportion among knee osteoarthritis patients, with extended sedentary periods. Consequently, healthcare providers should emphasize the importance of regular physical activity, employ evidence-based pain management strategies, enhance social support networks, and advise patients to promptly implement measures improving knee function while increasing their awareness of their own sedentary habits.
