Sleep Quality and Suicidal Ideation in Navy Personnel Seeking Psychiatric Consultation at the Hospital Naval de Veracruz
##plugins.themes.bootstrap3.article.main##
Abstract
Introduction. Very short sleep duration every night leads to a nearly threefold increase in the risk of death by suicide.
Objective. To determine whether there is an association between sleep quality and suicidal ideation in Mexican naval personnel.
Method. Transversal analytical study. The research was undertaken at the Hospital Naval de Especialidades de Veracruz, where a questionnaire on sociodemographic variables, the Pittsburgh Sleep Quality Index and a psychiatric interview including questions on suicidal risk were administered to naval personnel attending an outpatient psychiatry clinic.
Results. The observed sample comprised 216 participants. In the logistic regression analysis, certain factors were associated with suicidal ideation regardless of age, sex and presentation of depressive disorders, including interrupted sleep (OR = 1.97, p = .042), snoring (OR = 2.48, p = .036), interrupted sleep due to cold (OR = 3.59, p = .002) or heat (OR = 2.88, p = .007), nightmares (OR = 3.69, p = .002), pain (OR = 3.35, p = .002) and individual perception of sleep quality (OR = 2.13, p = .016).
Discussion and conclusion. Sleep interruption due to environmental variables, nightmares, snoring and pain in the naval military population may be an independent factor for suicidal ideation. However, studies with a larger sample not restricted to the clinical population are required.
