Sleep hygiene behaviours mediate the association between health/e‐health literacy and mental wellbeing

Abstract

AbstractBackgroundHealth literacy and e‐health literacy are important factors helping people shape awareness of health behaviours in different aspects, including sleep hygiene behaviours. Good sleep hygiene behaviours promote sleep quality and are beneficial to overall mental wellbeing.ObjectiveWe aimed to examine if sleep hygiene behaviours may mediate the association between health literacy/e‐health literacy and mental wellbeing.MethodsAdult Iranian subjects (n = 9775; mean [SD] age = 36.44 [11.97] years; 67.3% females) completed the Health Literacy Instrument for Adults, eHealth Literacy Scale, three items on sleep hygiene behaviour that have been used in prior research and the Short Warwick Edinburgh Mental Wellbeing Scale. Data were then subjected to structural equation modelling (SEM) including 500 bootstrapping resampling to examine whether sleep hygiene is a mediator in the relationship between health literacy/e‐health literacy and mental wellbeing.FindingsBoth health literacy and e‐health literacy were significantly associated with mental wellbeing (r = .63 for health literacy and .39 for e‐health literacy; p < .001) and sleep hygiene behaviours (r = .58 for health literacy and .36 for e‐health literacy; p < .001). Sleep hygiene behaviours were significantly associated with mental wellbeing (r = .42; p < .001). Moreover, SEM that incorporated bootstrapping approaches indicated that sleep hygiene behaviours were significant mediators in the association between health literacy/e‐health literacy and mental wellbeing.ConclusionsWe conclude that health literacy and e‐health literacy are associated with mental health wellbeing in the Iranian population. Additionally, the association could be mediated via sleep hygiene behaviours.Patient or Public ContributionThe study was co‐designed with healthcare providers from the vice‐Chancellor's Office for Health Affairs of Qazvin University of Medical Sciences as equal partners. Moreover, the women's health volunteers were involved in the design of the study.
