Asthma has a significant impact on U.S. military expenditures and readiness
. Every year approximately 1,000 recruits are discharged for asthma during
their first 6 months of service. This study was done to evaluate the practi
ce of allowing some individuals with a history of asthma to enter military
service (waiving). A survival analysis was performed to compare length of t
ime until discharge and asthma-related failure for individuals waived for a
sthma (cases) and individuals not disqualified for asthma (controls). Cases
were 587 recruit applicants initially disqualified who received waivers fo
r asthma and accessed in the years 1995 to 1997. Controls were 1,761 matche
d enlisted recruits starting basic training in those years. No significant
differences were found with respect to general attrition. The statistical d
ifferences for asthma-related hospitalization or discharge did not translat
e into practical differences. Waiving for asthma was not a significant occu
pational liability in terms of asthma-related hospitalization or early mili
tary attrition.
