The Association between BMI and Osteoarthritis in Adults
Abstract Objectives: The prevalence of obesity-related symptomatic OA has been found to increase. We investigated the relationship between BMI and osteoarthritis in 14,058 20-85 year-old participants from the National Health and Nutrition Examination Survey (NHANES). Methods: To estimate the association between BMI and osteoarthritis, multivariate logistic regression analyses were conducted. Fitted smoothing curves. Results: After adjusting for other confounding factors, we found that BMI was positively correlated with osteoarthritis. On subgroup analyses, stratified by sex and race/ethnicity, the positive correlation between BMI and Osteoarthritis in men and women, as well as in whites, blacks, and Mexican Americans, still exists. Conclusions: Our study revealed a positive relationship between BMI and Osteoarthritis in most adults.
