Association between cardiorespiratory fitness and health care costs in hypertensive men.

Abstract Background and aims Hypertension increases healthcare costs, but the impact of cardiorespiratory fitness (CRF) on these costs is unknown. This study explored the association between healthcare costs and CRF among hypertensive and normotensive men. Methods We studied 9794 male subjects aged 58.5 ± 11.3 years from the Palo Alto Veterans Affairs Medical Center, including 6413 with and 3381 without hypertension. CRF was classified into four age-stratified categories according to metabolic equivalents (METs) derived from exercise testing: low fit (4.6 ± 1.2 METs; n = 2481), moderate fit (6.6 ± 1.2 METs; n = 2412), fit (8.0 ± 1.3 METs; n = 2505), and high fit (10.8 ± 2.1 METs; n = 2396). Annual costs per subject were quantified over eight years. Results Total annual healthcare costs were higher in subjects with hypertension ($34,794, 95% CI, 32,828 to 36,761) in comparison to non-hypertensive subjects ($30,221, 95% CI, 26,104 to 32,450) (p  Conclusions Higher CRF is associated with lower healthcare costs in men with and without hypertension. The impact of CRF on healthcare costs is more striking in those with hypertension.
