Incidence of adult onset XXXX in the US military: patterns by sex, race and age.

@entity1 @entity161 @entity716
BACKGROUND: There are limited data describing the epidemiology of adult-onset @entity161 in the United States. Although the military is not proportionately comparable in all demographic characteristics to the civilian population, it is drawn from all racial/ethnic subgroups, and members range in age from 17 to >60 years. We describe the incidence of hospitalization for new onset @entity161 among military members by sex, race, and age. METHODS: Using military inpatient data, we evaluated patterns of initial hospitalizations for @entity161 among military personnel for 2000-2009, focusing on sex, race, and age. No individual-level data were available. RESULTS: From 2000-2009, 1976 military personnel had a first @entity161 hospitalization, with an overall incidence rate of 0.14/1000 @entity1 -years. There were no consistent changes in rates over time. While overall incidence rates were similar for @entity1 and @entity1 (incidence rate ratio (IRR)=1.10), rates were higher among @entity1 than @entity1 below age 25; after 25-30 rates were higher among @entity1 . Incidence was higher among blacks and other racial groups, with IRR=2.0 and 1.3, respectively. CONCLUSION: Medical screening of military applicants prevents @entity1 with overt or a reported history of @entity716 , and most with serious behavior problems, from enlisting; therefore, first hospitalization is likely to reflect new illness. No pre-military socioeconomic data were available, however, essentially all study subjects were high school graduates; unmeasured differences in socioeconomic status were unlikely to explain the observed results. This report may provide lower bound estimates of the @entity161 incidence in the United States.
