Supportive Care in Cancer, 33(7), 609. https://doi.org/10.1007/s00520-025-09673-60941-43551433-7339https://hdl.handle.net/11268/16771This study analyzed the relationship between different levels of sleep difficulties and physical, mental, and emotional variables in long-term breast cancer survivors (LTBCSs), and identified predictors of sleep-related complaints. Five or more years post-diagnosis, 55% of LTBCSs experienced higher sleep difficulties, associated with poorer HRQoL, self-perceived physical fitness, mood, and increased CRF and pain. Key predictors explained 58.4% of variance in sleep difficulties.engjournal article10.1007/s00520-025-09673-6embargoed accessCiencias médicasCáncerMedicina preventivaGoal 3: Ensure healthy lives and promote well-being for all at all agesGoal 5: Achieve gender equality and empower all women and girlsGoal 10: Reduce inequality within and among countries
