Abstract
Background: It is known that physical activity is beneficial to the prevention of osteoarthritis, but specific discussions on which types and levels of physical activity are more effective in reducing the incidence of osteoarthritis are restricted. Purpose: This study is aimed at exploring the correlation concerning the types of physical activity, levels of physical activity, and the incidence of osteoarthritis by assessing the participation in five typical forms of physical activity (vigorous work activity, vigorous recreational activity, moderate work activity, moderate recreational activity, and walking or bicycling). Study Design: Cross-sectional study was conducted.
Methods: Self-reported data on specific domains of physical activity were obtained from individuals in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2020 with the use of the Physical Activity Questionnaire (PAQ). The incidence of osteoarthritis was assessed through the "Health Conditions" questionnaire section of NHANES. Weighted logistic regression analysis was employed to study the correlation between physical activity types and levels, and the incidence of osteoarthritis.
Conclusion: Different kinds of physical activity and physical activity levels have varying impacts on the incidence of osteoarthritis. Among the types of physical activity, vigorous recreational activity and moderate recreational activity are correlated with a reduced risk of osteoarthritis, while moderate work activity may contribute to a rising risk. Regarding physical activity levels, engaging in medium physical activity level appears to be protective against osteoarthritis.
