Abstract
OBJECTIVE: This study aimed to investigate the relationship between physical activity levels and periodontal health status among college students in Shanghai, with the goal of informing oral health policy recommendations. METHODS: A cross-sectional study was conducted from March 2023 to March 2024 involving 120 university students aged 18-29. Data was collected using the World Health Organization (WHO) oral health survey methods. Periodontal status was assessed using the Community Periodontal Index (CPI), and physical activity was measured with a simplified version of the International Physical Activity Questionnaire (IPAQ). Data analysis was performed using Statistical Package for the Social Sciences (SPSS) version 27.0 (IBM, USA), employing chi-square tests and multivariable logistic regression. RESULTS: Among the participants (77 males, 43 females), 70% met physical activity guidelines. Adjusting for gender, age, tooth brushing frequency, and dental floss use, insufficient physical activity was associated with higher odds of periodontitis (adjusted model: OR = 5.293, 95% CI = 1.334 to 20.993, p = 0.018). High-intensity physical activity significantly reduced the incidence of periodontitis (p = 0.006), while sedentary behavior showed no significant correlation (p = 0.176). CONCLUSION: Promoting physical activity among college students may enhance periodontal health, underscoring the need to integrate oral and public health initiatives.
