A118: Economic Burden of Chronic Diseases Attributed to PhysicalInactivity in China

<bold>Background/Purpose:</bold> The benefits of physical activity in reducing morbidity and mortality rates have been widely recognized in recent years. However, the impact of physical inactivity on direct healthcare costs remains poorly understood. This study aimed to assess the direct economic burden of hospitalization due to two common chronic diseases (cerebrovascular disease and diabetes) caused by physical inactivity, to inform public health awareness and policy-making. <bold>Methods:</bold> Utilizing data from the 2018 China Family Panel Studies and the China Health and Retirement Longitudinal Study, we selected 1,704 patients hospitalized for chronic diseases in the past year. Data were analyzed using ANCOVA with repeated measures and logistic regression to calculate the relative odds associated with physical inactivity, accounting for confounding factors like age, gender, education, marital status, and urban-rural residence. The Population Attributable Risk percent (PAR%) and the per capita direct disease burden attributable to physical inactivity were calculated to ascertain its impact on healthcare costs. <bold>Results:</bold> Compared to those who regularly engage in physical exercise, individuals with insufficient physical activity had a 38.3% higher odds of developing cerebrovascular disease (OR = 1.383, P = 0.011, CI = 1.076 - 1.778) and an 84.9% higher odds of developing diabetes (OR = 1.849, P &lt; 0.001, CI = 1.381 - 2.476). The direct economic burden for patients with cerebrovascular disease and diabetes was respectively ¥298,898.46 and ¥79,242.914, with physical inactivity accounting for ¥48,690.56 (PAR = 16.29%) and ¥23,883.81 (PAR = 30.14%) of these costs. This translates to a per capita direct economic burden due to physical inactivity of ¥172.66 and ¥113.73, respectively. <bold>Conclusion:</bold> The findings suggested that regular moderate physical exercise can significantly reduce healthcare costs related to chronic diseases. Physical inactivity not only increases the risk of disease but also imposes an economic burden on individuals and society. Thus, promoting a healthy lifestyle and encouraging active participation in physical exercise is crucial for reducing healthcare expenses and enhancing public health. Future research could explore demographic differences in the relationship between physical activity and healthcare costs.
