Purpose: To explore the prevalence of sleep disturbances and their effects on quality of life in adults with pituitary tumor or meningioma. Methods: This prospective study included 33 and 44 patients with pituitary tumor and meningioma, respectively. All participants completed a series of valid questionnaires for assessing sleep and quality of life; all participants wore 3-day actigraph prior to related treatment. The actigraph-derived sleep parameters included total sleep time, sleep onset latency, wake after sleep onset, sleep efficiency, and dichotomy index (I < O) value. Results: The prevalence of insomnia, excessive daytime sleepiness, and poor sleep quality was 46.8%, 6.5%, and 81.8%, respectively. The differences in these sleep parameters between patients with pituitary tumor and those with meningioma were nonsignificant. Only 27 participants completed the actigraphic assessments. The mean I < O value was 95.99%, and nearly 60% participants exhibited circadian rhythm disruption. Sleep quality was the only sleep variable independently correlated with preoperative quality of life, even after adjustments for confounders (B = 0.80, p = 0.02). Conclusions: Insomnia, poor sleep quality, and disrupted circadian rhythm are highly prevalent in adults with untreated pituitary tumor or meningioma. Sleep quality independently correlated with quality of life. We indirectly confirmed that tumor location may not be a possible cause of sleep changes.
