title: [Progress of research in osteoarthritis. Epidemiolgy of osteoarthritis in Japanese population. ~ The ROAD study ~].
abstract: To clarify the prevalence of osteoarthritis (OA) and osteoporosis (OP) and estimate the number of people with these conditions in Japan, we conducted a large-scale population-based cohort study entitled "Research on Osteoarthritis Against Disability (ROAD)". From the baseline data of the ROAD study, we found that the prevalence of knee OA in men and women was 42.0% and 61.5%, respectively, and that of lumbar OA was 80.6% and 61.5%, respectively. The estimated number of Japanese patients with knee OA and lumbar OA was approximately 25 million and 38 million, respectively.
