Sleep hygiene behaviors and actigraphic sleep: a pilot analysis of gender differences

Le résumé fourni par la source

Poor sleep hygiene is reported to impair subjective sleep and disrupt circadian system, yet the association between sleep hygiene and objective alterations in sleep continuity is scarcely studied. Moreover, the role of gender differences is largely neglected. In this pilot study, sixty-five adults (66% females) completed a psychometric assessment including the Sleep Hygiene Index (SHI) and wore an actigraph for one week for the assessment of sleep. No statistically significant gender differences on sleep hygiene practices were found. Bedtime and waketime were later in males than females. Males showed longer sleep onset latency (SOL), and wake after sleep onset (WASO), and lower sleep efficiency compared to females. General linear analyses showed that poorer sleep hygiene was associated with shorter SOL and longer WASO in males but not in females. Age, habitual insomnia and psychological distress did not influence the results. Current findings suggest a differential impact of sleep hygiene behaviors on objective alternations in males. While future research is needed to investigate the role of specific sleep promoting and sleep inhibiting behaviors on objective sleep, current results highlight the importance of considering gender differences in sleep hygiene research. Gender differences in homeostatic, circadian, and neuroendocrine factors related to sleep hygiene should be further investigated in mechanistic studies also considering non-binary participants.
