Abstract
Purpose: To examine the association between physical
activity, prevalence of hypertension, and
total healthcare and pharmaceutical
expenditure in the United States of America
(US).
Methods:
In this cross-sectional study, adult
United States
residents were included from the Medical Expenditure
Panel Survey (MEPS) for 2002. In the MEPS, physical
activity was defined as spending at least 30 min 3 times
a week in moderate to vigorous physical activity and the
diagnosis of hypertension was based on the patient’s
self-report. Logistic and multiple linear regression
models were used to calculate the risk of prevalent
hypertension in physically inactive individuals and
examine the association between physical activity and
healthcare expenditure after controlling for
confounders.
Results:
Hypertensive patients who were physically active
accounted for 46 % and the risk of hypertension was
higher in physically inactive individuals than in those
who were physically active (Odds ratio, 1.1; 95 %
Confidence interval, 1.07 to 1.12, p < 0.0001). Physical
activity in all individuals was associated with a
decrease in total healthcare expenditure by US$592 per
person (p < 0.0001) and pharmaceutical expenditure by
US$125 per person (p < 0.0001).
Conclusion:
Total healthcare and pharmaceutical expenditures were
significantly lower for physically active than
physically inactive individuals.
