OBJECTIVE: Osteoarthritis (OA) epidemiologic data are scarce in Europe. To estimate the prevalence of symptomatic knee and hip OA in a multiregional sample in France. DESIGN: A two-phase population-based survey was conducted in six regions in 2007-2009. On initial phone contact using random-digit dialing, subjects 40-75 years old were screened with a validated questionnaire. Subjects screened positive were invited for ascertainment: physical examination and hip and/or knee radiography (Kellgren-Lawrence grade≥2). Multiple imputation for data missing not-at-random was used to account for refusals. RESULTS: Of 63,232 homes contacted, 27,632 were eligible, 9621 subjects screened positive, 3707 participated fully in the ascertainment phase, and 1010 had symptomatic OA: 317 hip, 756 knee. Hip OA prevalence according to age class ranged from 0.9% to 3.9% for men and 0.7-5.1% for women. Knee OA ranged from 2.1% to 10.1% for men and 1.6-14.9% for women. Both differed by geographical region. The hip and knee standardized prevalence was 1.9% and 4.7% for men and 2.5% and 6.6% for women, respectively. CONCLUSIONS: This confirmed the feasibility of using a screening questionnaire for eliciting population-based estimates of OA. In France, it increases with age and is greater among women above the age of 50. The geographical disparity of hip and knee OA parallels the distribution of obesity.
