Abstract:This study provides a cross-sectional, population-based analysis of significant threshold shifts (STS) from over 83,000 audiograms on active duty members in the Navy Hearing Conservation Program Database for 1995–1999. Crude STS rates were lower for women than men (odds ration [OR], 0.82; 95% confidence interval [CI], 0.76–0.89; p = 0.0000) and lower for officer than enlisted (OR, 0.71; 95% CI, 0.66–0.76; p = 0.000000). STS rates also increased significantly with increasing age (χ2 for trend, 134; p = 0.0000). Compared with historical information, STS rates for officers were significantly lower (OR, 0.23; 95% CI, 0.18–0.27; p = 0.00000). Adjustment by logistic regression found STS rates were lower for women (OR, 0.837; 95% CI, 0.773–0.905; p = 0.000) and officer status (OR, 0.670; 95% CI, 0.619–0.725; p = 0.0000), and increased significantly with age. These findings warrant further investigation because they have programmatic implications on Navy hearing conservation and force health protection.
