PURPOSE: Insomnia symptoms are common in men after prostate cancer (PCa) treatment. Here we examined how sleep hygiene behaviors and psychological symptoms are related to insomnia symptoms in PCa patients.
METHODS: An online survey was published on social media and sent to PCa and general cancer organization mailing lists. The survey collected information on demographic, sleep hygiene, and psychological symptoms using validated questionnaires.
RESULTS: Data from 142 participants were compared based on the absence (age = 68.3 ± 8.9 years) and presence (age = 66.6 ± 9.0 years) of insomnia symptoms. Participants with insomnia symptoms had significantly higher levels of anxiety, depression, fatigue and sleepiness, and poorer sleep hygiene than participants without insomnia symptoms. Control variables (age, number of comorbidities, and BMI) accounted for 11.9% of the variance in insomnia symptoms. Inclusion of treatment history contributed an additional 1.6% of the variance in insomnia symptoms. Adding sleepiness, fatigue, anxiety, and depressive symptoms to the model explained an additional 44.6% of the variance in insomnia symptoms. Additionally, inclusion of the sleep hygiene items “I think, plan, or worry when I’m in bed” and “I sleep in an uncomfortable bedroom” explained an additional 3.6% of the variance in insomnia symptoms.
CONCLUSIONS: Poor sleep hygiene, fatigue, drowsiness, anxiety, and depressive symptoms were all associated with worse insomnia symptoms in PCa patients. Improving sleep hygiene and treating mental illnesses may help prevent and/or alleviate insomnia symptoms in PCa patients.
