RESUMEN
PURPOSE: A cancer diagnosis in young adulthood can negatively impact sleep quality. The present study describes sleep issues in young adults (YAs) and analyzes potential demographic and clinical characteristics related to sleep quality. METHODS: Canadian YAs (n = 359) diagnosed with cancer between ages 15-39 participated in the study. Pittsburgh Sleep Quality Index (PSQI) items were examined to identify specific sleep issues that occurred 3+ times per week. Logistic regression was used to examine demographic, clinical, and symptom-related variables associated with poor sleep quality (defined as a PSQI global score >8) and sleep medication use. RESULTS: Participants were predominantly female (87.5%) with an average age of 32 years. Of the sample, 52% had poor sleep quality, 55.5% took >30 min to fall asleep, 32.9% slept <7 h, and 54.6% reported a habitual sleep efficiency of <85%. YAs with poor sleep quality were 5.7 times more likely to report severe distress (p=<.001), as well as 1.8 times more likely to report poorer mental (p = .03) and physical functioning (p = .05). Nearly half (44%) of YAs used sleep medication to help them sleep. YAs who reported severe psychological distress were 2.4 times more likely to use sleeping medication (p = .01), whereas those with a household income ≥$100,000/year were half as likely to use medication to help with sleep (p = .04). CONCLUSION: Psychological distress is associated with worse sleep quality and sleep medication use in YA cancer survivors. Sleep quality may be a possible target for future research and intervention to promote long-term function and recovery.
