title: Prevalence of musculoskeletal pain in an elderly Korean population: results from the Korean Longitudinal Study on Health and Aging (KLoSHA).
abstract: The aim of this study is to estimate the prevalence of musculoskeletal (MSK) pain in the upper extremities (UE), low back, and lower extremities (LE) in an elderly population, and to identify related factors. In this cross-sectional cohort study, 1118 Korean elderly subjects were randomly selected from residents aged ≥65 years living in an urban city of Korea. The study data included presence of MSK pain, educational levels, activity levels over a 24h, monthly income, body mass indices and presence of depression. Estimated age- and gender-standardized prevalences of UE, low back, and LE pain were 62.6%, 72.6%, and 45.7%, respectively. The prevalence of LE pain increased with age, whereas those of UE pain and back pain did not. By multivariate analysis, a female gender and a low income were found to be significantly associated with pain at all sites, and obesity was related with low back and LE pain. Furthermore, an uneducated state was found to be associated with LE pain, and major depressive disorder to be obviously related to UE and LE pain. MSK pain was identified to be a common problem in the elderly Korean population, and a female gender was consistently associated with MSK pain.
