Identifying mood disorders and health-related quality of life of individuals submitted to mandatory military service.

ABSTRACT

OBJECTIVE: To assess the prevalence of mood disorders in Brazilian soldiers. METHODS: A total of 353 soldiers answered the following questionnaires the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Profile of Mood States (POMS), the medical outcomes study SF-36 questionnaire, the Baecke questionnaire to assess the level of habitual physical activity (HPA) and the socioeconomic (SE) status questionnaire. Participants were classified according to their desire to pursue a military career. RESULTS: Accordingly, 246 participants were allocated to a volunteer group (VG) and 107 to a non-volunteer group (NVG). According to the BDI data for both groups, 66.5% of the soldiers showed at least mild depressive symptoms. Additionally, the STAI data revealed that 27.8% and 8.4% of the soldiers showed high scores on state anxiety and trait anxiety, respectively. The POMS scores were higher in the NVG compared to the VG (Δ%=+263%, p<0.0001). Of the eight subscales, the SF-36 questionnaire showed statistical differences between the groups in the following five dimensions functioning capacity (p = 0.0046), pain (p = 0.0011), vitality (p < 0.0001), role limitations due to emotional problems (p < 0.0001) and mental health (p < 0.0001). CONCLUSIONS: Mood disorder levels were higher and health status and related quality of life levels were lower in the NVG as compared to the VG.
