Abstract/OtherAbstract:
PURPOSE: As a follow up to previous smaller-scale studies, the purpose of the present study was to examine the link between cardiorespiratory fitness (VO(2max;) maximum oxygen uptake) using a nationally representative U.S. sample of adults. METHOD: Data from the 1999-2004 National Health and Nutrition Examination Survey (NHANES) were used in the analyses. After exclusions, the final sample included 1,082 NHANES participants (20-49 years). VO(2max) was obtained from an established non-exercise prediction equation and through heart rate extrapolation during a treadmill-based submaximal test. Audiometry data was objectively-measured to obtain estimates of low (LPTA) and high (HPTA) pure tone frequency average. RESULTS: VO(2max) was not associated with hearing sensitivity when using the heart rate extrapolation method, but was significantly associated with hearing sensitivity (for women) when applying the non-exercise prediction equation for both LPTA and HPTA (p < 0.01). Women with higher predicted aerobic fitness were 6% more likely to have good hearing compared to worse hearing (RR: 1.06 [95% CI: 1.00, 1.13]; p = 0.05). CONCLUSIONS: Cardiorespiratory fitness was associated with hearing sensitivity using the non-exercise prediction equation. Further studies are needed to confirm these findings that suggest a potentially auditory-protective effect of cardiorespiratory fitness.
