Occupational Medicine Model and Asthma Military Recruitment.

Medical evidence hints that asymptomatic recruits with a history of childhood asthma, quiescent since their 13th birthday, are still at risk for adverse changes in their clinical status following unfavorable environmental exposures during military deployment or combat. Asthmatic persons, claiming none or few symptoms, may still manifest airflow obstruction and display biomarkers of airway inflammation even when they are relatively asymptomatic and experience few if any respiratory complaints. The occupational medicine model offers a credible foundation for acknowledging the importance of personal susceptibility in the pathogenesis of military-associated asthma. It is appropriate to re-explore the current military standard for recruits with asymptomatic childhood asthma (≥12 months) not prescribed antiasthma medications. Raising the acceptance age for these recruits may be a consideration. Unfortunately, there is no effectual screening test that recognizes such susceptible soldiers at risk for future asthma attacks. Nevertheless, there is general support for evidence-based, scientifically valid medical screening that judges fitness for military service. Screening tests comprising asthma biomarkers and genetic indices may better verify vulnerable soldiers destined to suffer future asthma reactivation.
