Correlation between quality of life and sleep quality of military firefighters

Introduction: Among the professions that are impacted by the work context, the military firefighter is mentioned, who carries out activities with danger, physical and emotional exhaustion, which can have an impact on quality of life. Objective: To analyze the relation between quality of sleep and quality of life of Brazilian Military Firefighters. Methods: Research with a quantitative, transversal, correlational and analytical approach, carried out with 129 military firefighters working in Rio Grande do Sul, Brazil, that had been performing operational and administrative assistance for more than six months. Questionnaires containing socio-occupational and lifestyle data, the Pittsburgh Sleep Quality Index and the World Health Organization Quality of Life to assess quality of life were used. Descriptive and analytical statistics were used. Results: The analysis of quality of life shows a higher average in the physical domain (77.52), a direct correlation between the physical domain and the other quality of life domains, and inverse correlations between global sleep quality and the domains of quality of life. Regarding sleep quality, a higher percentage of poor classification (71.3%) is observed in military firefighters. Conclusion: There was a predominance of workers with poor sleep quality and good perception of general quality of life. An inverse correlation was identified between sleep quality and the domains of quality of life. When comparing quality of life with sleep quality domains, a significant difference was identified.

Ecological Momentary Mood, Resilience, and Mental Health Status as Predictors of Quality of Life Among Young Adults Under Stress: A Structural Equation Modeling Analysis

Multiple internal factors, such as psychological resilience and mental health status, have been shown to contribute to overall quality of life (QoL). However, very few studies to date have examined how these factors contribute to QoL of youth and young adults in a stressful situation. Here, we studied the contribution of these factors, as well as of ecological momentary mood assessment, to QoL of young army recruits during their Basic Training Combat (BCT). To this end, we collected data from 156 male and female soldiers in a mixed-gender unit in the Israel Defense Forces (IDF). Using a mobile app installed on participants' phones, participants provided self-reports regarding their mental health status and psychological resilience at baseline, and QoL 2 weeks later. Momentary mood reporting was further collected during the 2-week interval period using a daily self-report mood scale (IMS-12). Structural equation modeling (SEM) was used to examine the interrelationships among the study variables based on a hypothesized model. We found that a model with all factors (gender, resilience, mental health status and momentary mood) provided a good fit for the data based on its fit indices [χ2(38) = 47.506, p = 0.139, CFI = 0.979, NFI = 0.910, RMSEA = 0.040, TLI = 0.964]. However, the only direct contributors to QoL were gender and momentary mood, accounting together for 61.5% of the variance of QoL. Psychological resilience and mental health status contributed to QoL only indirectly, through their associations with momentary mood. Collectively, these results highlight the importance of ecological momentary assessment of mental-health related factors such as mood to the prediction of QoL in young adults under stress. These findings may have broader implications for monitoring and improvement of well-being in young healthy populations as well as in clinical ones.
