Abstract
Introduction: Recent media and public attention have linked the naval tactical aircraft accelerative environment to potential neurological and mental health issues, but epidemiological research on tactical aviators is limited. This study reports the current prevalence of selected neurological and mental health disorders among naval tactical aviators and nontactical aviators.
Methods: A retrospective cohort-designed study was performed on 10,661 active-duty naval aviators identified within the Naval Fleet Training Management and Planning System. Their unique identification codes were associated with all available military electronic health records within the Military Health System Data Repository for certain neurological and mental health International Classification of Diseases codes from October 2000 through December 2024.
Results: In total 8593 active-duty naval aviators met inclusion criteria. Compared to tactical aviators, helicopter aviators had higher odds of behavioral health disorders overall [odds ratio (OR) 1.29, 95% confidence limits (CL) 1.10-1.52], adjustment disorders (OR 1.35, 95% CL 1.09-1.68), and posttraumatic stress disorder (OR 1.82, 95% CL 1.02-3.25). Reconnaissance aviators had higher odds of behavioral health disorders overall (OR 1.37, 95% CL 1.17-1.60), adjustment disorders (OR 1.5, 95% CL 1.22-1.85), posttraumatic stress disorder (OR 1.84, 95% CL 1.05-3.22), and anxiety (OR 1.33, 95% CL 1.05-1.70) compared to tactical aviators. No significant differences were observed between these cohorts for selected neurological conditions.
Discussion: Accelerative exposures in tactical naval aviation differ and are generally far lower than those seen in sports involving repetitive head impacts. Advances in medical imaging and neuro-biomarkers allow aeromedical researchers to examine this population for potential subclinical neurological changes.
