Demographic characteristics and behavioral information were collected through epidemiological surveys. All participants with joint pain underwent plain radiographic examination and were diagnosed by a professional orthopedist. Associations between smoking patterns and the prevalence of OA were assessed using binary logistic regression modeling.Results： Among 2638 individuals （men, 50.3% and women, 49.7%; mean age, 61.5 years） included in the analysis, 49.8% had radiographic OA and 27.5% had knee OA. The prevalence of radiographic OA was higher in women than in men （P〈0.001）. After adjusting for potential confounding factors, there was a nonsignificant correlation between smoking and OA prevalence in the muttivariate model. Odds ratios （ORs） for all types of OA and knee OA were higher in active and passive smokers than in nonsmoking individuals after adjustments （OR 1.374; 95% confidence interval [CI] 1.049-1.802; OR 1.440; 95% CI 1.059-1.958, respectively）.Conclusions： This study showed th at smoking may not be an independent risk factor for OA; however, there was a positive correlation between active and passive smoking and OA.展开更多
