Objective: Many people experience orthopaedic problems (OPPs), such as knee joint pain, hip joint pain, low back pain, and knee stiffness in their lifetimes. OPPs can impair lower extremity function, cause depression, and worsen quality of life. The aim of this study was to investigate the association between sedentary time (SDT) and OPPs. Design: Retrospective cross-sectional study. Setting: This study used data from the 2014–2015 Korea National Health and Nutrition Examination Survey. Survey participants with previous or current osteoarthritis or rheumatoid arthritis, as diagnosed by a doctor, were excluded. OPPs were defined as knee joint pain, hip joint pain, low back pain, and knee stiffness. The cut-off value for SDT was 7.5 hours/day. The study population comprised 3,671 people (1), 856 men and 1,815 women), all of whom were ≥50 years-old. Multiple logistic regression analyses were performed. Results: A total of 328 men (17.7%) and 519 women (28.6%) had OPPs. Men with SDTs ≥7.5 hours had a greater risk of OPPs than did men with SDTs <7.5 hours (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.08–1.93). A pink-collar job, physical inactivity during leisure time, and passive (e.g. riding in a car or train) versus active (e.g. walking or riding a bicycle) transportation predicted OPPs in men with SDTs ≥7.5 hours. SDT was a risk factor for knee joint pain in men (OR, 1.80; 95% CI, 1.11–2.92) and hip joint pain in women (OR, 2.05; 95% CI, 1.35–3.11). Conclusions: In men, prolonged SDT is a risk factor for OPPs. More physical activity programmes should be launched at the community level for people ≥50 years-old to reduce the occurrence of OPPs.
