Abstract
BACKGROUND: Reduced sleep can be associated with a risk of health problems. Information technologies (IT) professionals often work long hours and this could have an effect on their sleep quality. AIMS: To examine the prevalence of sleep debt, insomnia and long working hours among Finnish IT professionals and to analyse which specific work-related factors are associated with shortened sleep. METHODS: Cross-sectional, representative data from a questionnaire survey of IT professionals. Hierarchical regression analyses were applied to investigate relationships of sleep debt and insomnia. RESULTS: A total of 2,334 IT professionals responded to the survey. Thirty-seven per cent reported sleep debt of at least 1 h and 6% of at least 2 h, while 16% reported insomnia. Twenty-seven per cent worked for a minimum of 50 h a week, while 31% spent at least 50 h a week on work. The most important factors associated with both sleep debt and insomnia were work-related demands requiring long hours, mental stamina and problem solving and positive perceptions of work, such as job control and importance of the respondents' own work in their life. CONCLUSIONS: Even though long working hours were common among IT professionals in Finland, sleep debt and insomnia were not. Work-related factors were associated with insufficient sleep.
