Correlates of disrupted sleep–wake variables in patients with advanced cancer

摘要: Objectives High rates of sleep difficulties have been found in patients with advanced cancer. However, not much is known about factors that are associated impairments this population and could constitute their potential risk or consequences. This study conducted cancer receiving palliative care aimed to evaluate the relationships subjective (sleep diary; Insomnia Severity Index, ISI) objective (actigraphy) sleep–wake variables several physical psychological symptoms, maladaptive behaviours, erroneous beliefs sleep, quality life, time death environmental factors. Methods The sample was composed 57 community-dwelling an Eastern Cooperative Oncology Group Scale score 2 3. Actigraphic, light sound recording a daily pain diary were completed for seven consecutive days. A battery self-report scales also administered. Results Greater disruptions more consistently worse symptoms than variables. Disrupted parameters greater frequency behaviours. Finally, nocturnal noise bedroom correlated while lower 24-hour exposure disruption subjectively assessed only. Conclusions Although longitudinal studies needed establish etiology cancer, our findings suggest behaviours can contribute development persistence need be adequately addressed.
