Résumé

Objectives: To determinate the prevalence of symptomatic hands and knees osteoarthritis of a random sample, the variables associated with its presence and its impact in quality of life and level of dependency. Methods: Observational study, on a random sample (Cambre, A Coruña; n=707 patients) (α=0,05; precisión: ±4%). After obtaining informed consent (CEIC approval 2008/264), anthropometric variables, comorbidity, laboratory parameters, medical history, quality of life, level of dependency, and hands and knees examination were studied. To assess pain, stiffness, and physical function were used WOMAC and Lequesne questionnaires. Descriptive and multivariate logistic regression analysis. Results: 56.3% of the people studied were women, the mean age was 61.75 years. The prevalence of symptomatic hands osteoarthritis was 38% and in at least one knee was 29.3%. People with knee osteoarthritis had a worse quality of life than the general population as measured by the SF-36 on their physical component (52.25 ± 9.11 vs. 55.08 ± 7.37), Lequesne (8.97 ± 4.43 vs 1.92 ± 2.64) and WOMAC questionnaires. Conclusions: There is a high prevalence of osteoarthritis that is modified by gender, age and BMI. Patients with knee osteoarthritis had poorer quality of life than the general population.
