The Association Between Physical Activity and Health Care Risk Management in Individuals With Disabilities

Despite the increasing economic burden of people with disabilities (PWDs) over time, the impact of physical activity on PWDs in the Republic of Korea (ROK) remains relatively unexplored. Thus, we examined the association between physical activity and disease risk, health care utilization, and expenditures for PWDs in the ROK. We considered gender differences across eight diseases using the National Health Insurance (NHI) panel data from 2013 to 2019. The sample consisted of PWDs who underwent regular medical check-ups and were aged 40 years and above, aligning with the NHI's health screening program targeting beneficiaries in this age range. The final sample included 281 142 healthy PWDs. Among them, 44.1% (n = 124 061) engaged in physical activity, while the remaining 45.9% (n = 157 081) did not participate in any physical activity. The results show a negative association between physical activity and the incidence of various diseases among both genders. Health care utilization exhibited gender and disease-based variations, with men and women demonstrating higher utilization rates in the absence of physical activity. Health care expenditures also differed based on gender and disease, as men and women displayed higher costs in the absence of physical activity. Consequently, public policymakers should establish tailored activity programs for PWDs, adhering to activity guidelines designed for this population.
