prevalence of radiographic lumbar Spondylosis and its association with low back pain in elderly subjects of population based cohorts the road study
Annals of the Rheumatic Diseases, 2009Co-Authors: Shigeyuki Muraki, Hiroyuki Oka, Toru Akune, Akihiko Mabuchi, Yoshio Enyo, Muneto Yoshida, Akihiko Saika, Takao Suzuki, Hideyo Yoshida, Hideaki IshibashiAbstract:Objectives: Although lumbar Spondylosis is a major cause of low back pain and disability in the elderly, few epidemiologic studies have been performed. We investigated the prevalence of radiographic lumbar Spondylosis using a large-scale population, and examined the association with low back pain. Methods: From a nationwide cohort study ROAD (Research on Osteoarthritis Against Disability), 2,288 participants (≥60 years; 818 men and 1,470 women) living in urban, mountainous and seacoast communities were analyzed. The radiographic severity at lumbar intervertebral levels from L1/2 to L5/S was determined by the Kellgren/Lawrence (KL) grading. Results: In the overall population, prevalence of radiographic Spondylosis with KL≥2 and ≥3 at the severest intervertebral level was 75.8 and 50.4%, respectively, and that of low back pain was 28.8%. Although the KL≥2 Spondylosis was more prevalent in men, the KL≥2 Spondylosis and low back pain were more prevalent in women. Age and body mass index were risk factors for both KL≥2 and KL≥3 Spondylosis. Although KL=2 Spondylosis was not significantly associated with low back pain compared to KL=0 or 1, KL≥3 Spondylosis was related to the pain only in women. Conclusions: The present cross-sectional study using a large population revealed a high prevalence of radiographic lumbar Spondylosis in the elderly. Gender seems to be distinctly associated with KL≥2 and KL≥3 lumbar Spondylosis, and disc space narrowing with or without osteophytosis in women may be a risk factor for low back pain.

association of occupational activity with radiographic knee osteoarthritis and lumbar Spondylosis in elderly patients of population based cohorts a large scale population based study
Arthritis & Rheumatism, 2009Co-Authors: Shigeyuki Muraki, Hiroyuki Oka, Toru Akune, Akihiko Mabuchi, Yoshio Enyo, Akihiko Saika, Munehito Yoshida, Kozo Nakamura, Hiroshi Kawaguchi, Noriko YoshimuraAbstract:Objective To investigate the risk of radiographic knee osteoarthritis (OA) and lumbar Spondylosis associated with occupational activity in elderly Japanese subjects using the large-scale population-based cohort of the Research on Osteoarthritis Against Disability (ROAD) study. Methods From the baseline survey of the ROAD study, 1,471 participants age > or =50 years (531 men and 940 women) living in mountainous and seacoast communities were analyzed. Information collected included a lifetime occupational history and details of specific work place physical activities. Radiographic severity at the knee and lumbar spine was determined by the Kellgren/Lawrence (K/L) grading system. Results The prevalence of K/L grade > or =2 knee OA and lumbar Spondylosis among agricultural, forestry, and fishery workers was significantly higher than among clerical workers and technical experts in the overall population. For occupational activities, sitting on a chair had a significant inverse association with K/L grade > or =2 knee OA and lumbar Spondylosis. Standing, walking, climbing, and heavy lifting were associated with K/L grade > or =2 knee OA, but were not associated with K/L grade > or =2 lumbar Spondylosis. Kneeling and squatting were associated with K/L grade > or =3 knee OA. Conclusion This cross-sectional study using a population-based cohort suggests that sitting on a chair is a significant protective factor against both radiographic knee OA and lumbar Spondylosis in Japanese subjects. An occupational activity that includes heavy lifting appears to have a greater effect on knee OA than on lumbar Spondylosis.
