Background: The purpose of this study was to document the prevalence of shoulder osteoarthritis (OA) in middle and old age in a village population, to determine the risk factors and shoulder function for shoulder OA.
Methods: A total of 541 residents were participated. The mean age of respondents was 65.2 (range, 40-89 years) years old, and 341 (63.0%) were women. Bilateral shoulder radiographs were taken, and the grade of OA was evaluated using the Samilson-Prieto method. Shoulder pain, shoulder ROM, and muscle strength were evaluated. The relationship between shoulder OA and these items was examined using univariate analyses and logistic regression analysis.
Results: Radiographic shoulder OA was detected in 94 people (17.4%). There were 60 shoulders of grade 1 (11.1%), 26 of grade 2 (4.8%), and 8 of grade 3 (1.5%). Intriguingly, age was a risk factor according to the grade of shoulder OA.
Conclusion: According to the logistic regression analysis, the shoulder OA has a relationship with age.
