Abstract/OtherAbstract:
Study Design. A community-based, cross-sectional study that is part of the prospective Korean Health and Genome Study.Objective. To determine the prevalence of low back pain (LBP) among middle-aged and elderly rural community residents in Korea and to examine the relevant risk factors, including activities reflecting the Asian lifestyle, and the relationship between radiographic features of degenerative changes in the lumbar spine and LBP.Summary of Background Data. The prevalence and implication of LBP among the elderly, particularly Asians, are underrepresented in previous reports.Methods. Data for LBP were collected for 4181 subjects from a rural farming community. The point and cumulative lifetime prevalences of LBP were obtained in addition to measurement of the severity of LBP. Lateral lumbar spine radiographs were taken according to a standard protocol.Results. The mean age of the study subjects was 56 years and 55% were females. The lifetime prevalence of LBP was 53.8%, with women having a higher prevalence. The point and 6-month prevalences were also higher among women. The lifetime, point, and 6-month prevalences increased with age in both genders, except for lifetime prevalence in men. The prevalence of LBP ≥ grade 3 was significantly higher in women and increased significantly with age, particularly in women. Both lifetime and point prevalence of LBP were significantly associated with age, female gender, and time spent squatting. After adjusting for age and gender, the presence of disc space narrowing, osteophytes and advanced Kellgren-Lawrence grade in lumbar radiograph was associated with LBP.Conclusion. The prevalence of LBP is comparable between these Korean community residents and other population groups. Risk factors associated with LBP included advanced age, female sex, squatting, the presence of osteophytes, joint space narrowing and advanced K-L grading on lumbar radiograph.
