Prevalence of Ischemia, Health-Related Quality of Life, Medical use and Expenses by Physical Activity and Ischemia Status in Korean Adults

Abstract

PURPOSE: The purpose of this study is to analyze the different prevalence of ischemia of Korea adults, and to compare the HealthRelated Quality of Life (HRQoL), annual personal medical use and expenses according to physical activity and ischemia status.METHODS: The 2018 Korea Medical Panel data was used (13,791 adults and 604 ischemia). Physical activity was measured with IPAQ and converted to MET-minutes per week. The physical activity group was classified as less than 600 MET-min per week in the inactive group, 600-3,000 MET-min per week in the minimally active group, and 3,000 MET-min more per week in the active group.RESULTS: The prevalence of ischemia was low in the inactive group compared to the minimally active group and the active group (OR=0.75, p<.01) and the active group (OR=0.36, p<.001). In both ischemic and non-ischemic groups, HRQoL was the lowest in the inactive group (p<.05). Inpatient days and emergency days showed no significant difference in according to the physical activity level and the ischemia status. However, within the group with ischemia, the outpatient days of inactive group were 42.8% higher (p<.05) and minimally active group was 4.3% higher (p>.05) compared to the active group (32.5±32.1 days) respectively. Within the group with ischemia, the medical expenses of inactive group were 5.2% lower (p>.05) and minimally active group was 33.9% lower (p<.05) compared to the active group ($1,738±2,457) respectively.CONCLUSIONS: Higher physical activity results in a lower prevalence of ischemia, and higher physical activity results in positive HRQoL and outpatient days in ischemia group. However Annual personal medical expenses showed a significant difference according to the level of physical activity in ischemia group.
