The prevalence of knee OA in community-based elders
Main Article Content
Abstract
Background: Knee OA is one of the most common musculoskeletal problem affecting daily life and quality of life in the elders.
Objectives: To determine the prevalence of knee OA in community-based elders and related factors.
Methods: This cross-sectional survey was performed in elders living in Umpawa province, Samutsongkram. The prevalence of knee OA was determined by using the American Rheumatism Association criteria of knee pain, crepitus on moving joints, and morning stiffness of less than 30 minutes. In addition, Quadriceps strength measured by dynamometer, gait speed (6-meter walk) and body mass index (BMI) were evaluated. Then, all factors related to knee OA were analyzed.
Results: Eighty-six from 243 elders were diagnosed knee OA with the prevalence of 35.4 (95%CI: 29.6, 41.6). The prevalence in female was more than male (39.8% vs. 22.6%). This prevalence showed increasing trend as they aged (33.3% in 60-69 years, 37.8% in age ≥ 70 years). Factors related to knee OA were female sex (adjusted OR 2.13 with 95%CI: 1.07, 4.24) and BMI ≥23.0 kg/m2 (adjusted OR 2.46 with 95%CI: 1.37, 4.42).
Conclusion: Approximately one-third of community -dwelling elders was found to be knee OA. Female and elders with high BMI should be screened for knee OA.
