Abstract 13: Economic Impact of Moderate-vigorous Physical Activity Among Those with and without Established Cardiovascular Disease: 2012 Medical Expenditure Panel Survey
Background: Physical activity (PA) is an established factor for favorable cardiovascular disease (CVD) outcomes and quality of life. However, to date little is available on PA’s independent impact on healthcare cost. In this study, we aimed to estimate this effect on medical expenditure from a nationally representative cohort with and without CVD.
Methods: The 2012 Medical Expenditure Panel Survey data was analyzed. Our study population was limited to non-institutionalized adults ≥ 40 years of age. Variables of interest were CVD (coronary artery disease, stroke, heart failure, dysrhythmias or peripheral artery disease), modifiable risk factors (MRF; hypertension, diabetes mellitus, hypercholesterolemia, smoking, and/or obesity), and PA (dichotomous variable: defined as moderate-vigorous exercise of ≥ 30 minutes, 5 times/week). Two-part econometric models were utilized to study cost data; a generalized linear model with gamma distribution and link log was used to assess expenditures per capita, taking into consideration the survey’s complex design.
Results: Our final study sample consisted of 15,651 surveyed individuals (mean age: 58.5 ± 12 years, 46% male). Overall, 46% engaged in at least moderate exercise, translating to 21 million physically active adults in the U.S. Of those with CVD, 34% reported PA, vs. 47% without CVD. In those without CVD, a higher prevalence of PA was noted with lower MRF burden (≥ 3: 35%, 2: 44%, 0-1: 53%). Generally, participants reporting moderate-vigorous PA incurred significantly lower healthcare costs, seen both in those with and without CVD. Among those without CVD, those engaged in moderate-vigorous PA with 0-1 & ≥ 3 MRF had $1,038 & $1,785 less healthcare expenditure, respectively, than their less physically active counterparts.
Conclusion: In addition to tremendously improving CVD risk, moderate-vigorous PA is also associated with significantly less healthcare spending. Our findings further reinforce the importance of physical activity in health promotion and CVD prevention.
