Military service-aggravated asthma improves at two-year follow-up.

Background: During military service young men (age 19-21 years) are exposed to many predisposing factors for asthma. We aimed to study the short-term prognosis of asthma after the military service.

Methods: All 216 men with verified asthma in 2004-2005 from the register of the Central Military Hospital were included in the study.
