Comparison of nondeployable hearing profiles by Army component (Active Duty, National Guard, and Reserve) and by gender.

The Hearing Conservation Service at Fort Bliss conducted baseline-hearing assessments from January 2003 to March 2005 on 14,974 soldiers in the Active Duty (AD), National Guard (NG), and Reserve Component (RC). The percentages of soldiers with >H-2 (i.e., nondeployable) hearing profiles based on Army component and gender are as follows: AD male = 2.21%; AD female = 0.65%; NG male = 5.05%; NG female = 1.64%; RC male = 5.02%; and RC female = 0.54%. Female soldiers in all three components and AD male soldiers are not significantly different (p < 0.05) from each other and have a significantly lower percentage of >H-2 hearing profiles than NG and RC male soldiers after adjusting for age. With the Army engaged in worldwide missions, these results should prove useful to commanders and medical officers for assessing deployment capabilities and for hearing conservation interventions.
