Analysis of Navy Physical Evaluation Board diagnoses (1998-2000).

An analysis is provided from 19,265 Physical Evaluation Board diagnoses from 10,406 Navy personnel from 1998 to 2000. The leading diagnostic categories were musculoskeletal and mental disorders as well as for subgroups of women and officers. Musculoskeletal conditions were 41.6% of the diagnoses and decreased with advancing age (42.9% for <30 years; 41.1% for 30-40 years; 37.6% for >40 years; chi2 for trend [1 df] = 26.4; p = 0.000). Mental disorders were 11.8% of the diagnoses and also decreased with advancing age (14.1% for <30 years; 10.4% for 30-40 years; 8.8% for >40 years; chi2 for trend [1 df] = 84; p = 0.000). Diagnoses for injury and poisoning (8.9%), nervous system (7.6%), and ill-defined conditions (4.7%) completed the top five categories below age 40 years, whereas circulatory disorders were evident after age 40 years. These findings suggest priorities for reducing overall medical disability losses in our active duty Navy forces.
