Mental Health in F-111 Maintenance Workers: The Study of Health Outcomes in Aircraft Maintenance Personnel (SHOAMP) General Health and Medical Study

OBJECTIVE: We sought to contrast mood disorder symptoms in F-111 aircraft Deseal/Reseal maintenance personnel with appropriate comparisons. METHODS: Participants completed a comprehensive health assessment, including measures of mood disorder, self-reported mood symptom questionnaire items, and review of anxiolytic and depression medication. Multiple logistic regression was conducted for each outcome using exposure group and potential confounders as explanatory variables. RESULTS: There was high agreement between self-reported mood disturbance and objective tests. The exposed group was more likely to self-report previous diagnoses of depression/anxiety, had higher use of antidepressant medications, and had increased risk of diagnosis of depression/anxiety. Results were consistently strong against both comparison groups, with the exposed more likely to have mental distress and social dysfunction when compared with the Australian population. CONCLUSIONS: There is robust evidence for an association between F-111 Deseal/Reseal exposure and impaired mental health.
