Abstract

Objectives: Shiftworkers routinely obtain inadequate sleep, which has major health consequences. Sleep hygiene describes a range of behaviours, lifestyle and environmental factors that can improve sleep. To date, limited research has examined sleep hygiene in shiftworkers. This study aimed to assess the sociodemographic and behavioural correlates of sleep hygiene knowledge and engagement with sleep hygiene practices in Australian shiftworkers.

Study Design: An online, cross-sectional survey.

Setting and Participants: Australian adults from across multiple industries (n = 588) who work shift work.

Measures: The online survey included questions regarding sleep hygiene knowledge, and questions from modified versions of the Pittsburgh Sleep Quality Index and Sleep Hygiene Index.

Results: Of the 588 participants, 52.9% reported having heard of ‘sleep hygiene’. Of these participants, 77.5% reported understanding the term moderately, extremely or very well. Engagement with each sleep hygiene practice was varied. Common sleep hygiene practices were controlling the bedroom environment (e.g., a cool, dark and quiet bedroom). Less common practices were avoiding light as bedtime approaches. Logistic regressions revealed that shiftworkers who had heard of sleep hygiene were more likely to engage in sleep hygiene practices and had better sleep quality compared to those who had not heard of sleep hygiene. Increased engagement in sleep hygiene practices did not predict the likelihood of individuals reporting better sleep quality.

Conclusions: Shiftworkers demonstrated varied knowledge, understanding and engagement with individual sleep hygiene practices. Future research should focus on the development of sleep hygiene interventions that accommodate the unique challenges of shift work to optimise sleep.

Methods

The data was collected through an anonymous online survey using Qualtrics (Version [XM] Copyright © 2020) and divided into three sections; i) demographic and work characteristics, ii) sleep hygiene knowledge and practices, and iii) sleep quantity and quality. The survey included a total of 29 questions drawn from the Pittsburgh Sleep Quality Index (PSQI) , as well as, questions modified from the Sleep Hygiene Index (SHI).

The data was exported into and excell spreadsheet for cleaning, the uploaded to SPSS for analysis.
