    From Sleep Monitoring to Digital Determinants: Understanding the Role of Technology in Older Adults' Sleep Health2024Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: As the global population ages and digital technology advances, the link between technology and sleep health in older adults becomes increasingly important. Digital tools can improve sleep through monitoring devices, increased digital social participation (DSP), and calming bedtime routines, but they also pose risks by disrupting sleep through device usage and the demands of a 24/7 society.

    Objectives: This thesis explores the use of digital technologies in understanding sleep and its determinants in older adults and examines sleep health and its relationship with technology use in this population.

    Method: We conducted a scoping review (Study1) and a cross-sectional quantitative population-based study (Study2). We identified 54 articles on home-based sleep monitoring technologies, identifying devices and their associated sleep parameters, predictors, and outcomes. We proceeded to examine the relationship between digital technology use and sleep health in older adults where we focused on technology use, DSP, technology enthusiasm, and anxiety. The analysis included both descriptive and inferential statistics.

    Results: We found that wrist-worn actigraphy sensors are the most commonly used for home-based sleep monitoring in older adults, measuring total sleep time (TST), wake after sleep onset (WASO), and sleep efficiency (SE). Few studies used EEG or explored REM and NREM stages. We found six categories of predictors and outcomes. We found that in-bed behaviors like screen use were associated with TST, WASO, and SE (Study1). In quantitative analysis of a sample of 436 older adults (Study2), we found that increased technology use during awake after sleep-onset was associated with poor sleep timing. There was a positive correlation between DSP and technology enthusiasm with sleep health. Better DSP scores predicted better sleep satisfaction, efficiency, and duration. Conversely, technology anxiety was linked to poorer sleep health, including lower satisfaction, efficiency, and timing. Using a screen before sleep predicted better sleep timing and significantly better sleep health scores.

    Conclusion: Together, these studies provide a comprehensive understanding of the positive and the negative aspects of how digital technologies impact sleep health inolder adults. The research emphasizes the need for a balanced approach to technology use, harnessing its benefits while minimizing negative effects.
