Abstract: 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 8.5 hours daily (9). The mean SDT in Korea in 2013 was 6.1 hours/day (10). Several studies have explored the potential association between SDT and OPPs (11) or injuries (12). They showed longer SDT might be associated with OPPS, especially chronic back pain and orthopaedic injuries. Others, however, showed increased amount of SDT after having knee arthroplasty or hip fracture (13, 14). Several studies have examined the health problems potentially associated with prolonged SDT: major depressive disorder (15), metabolic syndrome (16), diabetes (17), cardiovascular disease (17), and all-cause mortality (18). Because reduced SDT time has significant health benefits, there are guidelines recommending at least 150 minutes of moderate intensity exercise weekly and less time spent sitting (19, 20). The aim of this study was to investigate the association between SDT and OPPs in people without past or current osteoarthritis or rheumatoid arthritis.
Orthopaedic problems (OPPs), such as knee joint pain, hip joint pain, low back pain, and knee stiffness, are common. In 2010, 23.1% of Koreans (11.7% of men and 31.9% of women) ≥50 years-old experienced knee joint pain lasting ≥30 days during a 3-month period (1). In 2012, the lifetime prevalence of low back pain in Koreans was 61.3%,
