Abstract

Purpose
An established link exists between overactive bladder (OAB) syndrome and impaired sleep. However, earlier research on this subject only focused on the general population, and certain patient subgroups have not been examined adequately. Depressed patients constitute a unique population because of a possible bidirectional relationship between OAB and depression. Thus, we investigated the association between OAB symptoms and sleep quality in patients with depression.
Methods
In this prospective, cross-sectional study, we analyzed data on depression, sleep quality, and OAB symptoms from depressed patients treated at our department of adult psychiatry. Data were collected with the Hamilton Rating Scale for Depression, the Holland Sleep Disorders Questionnaire, the Athens Insomnia Scale, and the OAB Module of the International Consultation on Incontinence Questionnaire.
Results
In total, 102 patients treated for depression were enrolled. Thirteen patients (12.7%) met the diagnostic threshold of OAB with the International Consultation on Incontinence Questionnaire OAB Module. Patients with depression and concomitant OAB had significantly higher scores on the Holland Sleep Disorders Questionnaire than patients classified as nonOAB (P<0.01). OAB patients also had a higher risk of insomnia relative to non-OAB individuals (P<0.05). In addition, the relationship between OAB symptoms and sleep quality in patients with depression was independent from age and sex.
Conclusions
In our cohort composed exclusively of individuals treated for depression, OAB symptoms were present in a significant proportion of patients, and OAB negatively affected sleep quality. Therefore, we recommend that OAB symptoms should be assessed collectively in patients with depression.
