Assessment of the Quality of Sleep and Sleep Disorders Among the Professional and Volunteer Firefighters of Loire (FIRESLEEP)

Studies have shown that schedules that most disrupt the normal circadian rhythm have the most harmful consequences. Firefighters positive for a sleep disorder have a higher risk of depression and anxiety; they report more traffic accidents, falling asleep during driving, and worth health felt. Furthermore, some studies suggest that sleep disorders are risk factors for cardiovascular disease. This activity is responsible of a worth quality of sleep that could induce a lower effectiveness of emergency response. The consequences of this schedules on sleep and health of French firemen have never been studied.

Intervention / Treatment

professional and voluntary firefighter; Professional and voluntary firefighter in Service Departmental Fire and Rescue of Loire will be included. They will have to answer at the self-administrated questionnaires. It is composed of 5 parts: socio-demographic data and personal medical history, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, Insomnia Severity Index (ISI) and stop-BANG questionnaire.

Diagnostic test: socio-demographic data and personal medical history; Socio-demographic data and personal medical history is a self-administered questionnaire.; Diagnostic test: Pittsburgh Sleep Quality Index (PSQI); Pittsburgh Sleep Quality Index (PSQI) is a self-administered questionnaire. This score evaluates sleep disturbances.; Diagnostic test: Epworth Sleepiness Scale; Epworth Sleepiness Scale is a self-administered questionnaire. This score evaluates excessive drowsiness.; Diagnostic test: Insomnia Severity Index (ISI); Insomnia Severity Index (ISI) is a self-administered questionnaire. This score evaluates insomnia severity.; Diagnostic test: stop-BANG questionnaire; Stop-BANG is a self-administered questionnaire. This score evaluates Obstructive Sleep Apnea (OSA).
