Evaluation of Sleep Quality and Quantity of Patients with Benign Prostatic Hyperplasia Using the Medical Outcomes Study-sleep Scale

Abstract

Objective: This study aimed to evaluate the sleep quality and quantity of patients with benign prostate hyperplasia (BPH) and compare them with that of a control group using the Medical Outcomes Study-sleep scale (MOS-SS). Materials and Methods: The study included 114 consecutive men who were recruited between 2014 and 2018. Voiding patterns of patients with BPH were evaluated by free uroflowmetry, and symptom scores were evaluated using the International Prostate Symptom score (IPSS). Sleep quality and quantity of all patients were evaluated using the MOS-SS questionnaire. The participants were divided into two groups: 57 BPH patients (group 1) and 57 healthy individuals (group 2). They were compared statistically in terms of MOS-SS subdomains. The relationship between MOS-SS subdomains and IPSS, free uroflowmetry parameters, and post-voiding residual urine volume (PVR) was evaluated in BPH patients. Factors affecting the MOS-SS subdomains were also investigated. Results: The mean age of group 1 was higher than that of group 2 (67 +/- 9 vs 52 +/- 11 years, p<0.001). All MOS-SS subdomain scores except for snoring were adversely affected in group 1, and there was a statistically significant difference between the groups (p<0.001). A mild to moderate significant correlation was found between the MOS-SS subdomain scores and IPSS, free uroflowmetry parameters, and PVR. In multivariate analysis, free uroflowmetry parameters and PVR were found to be independent risk factors for predicting deterioration in the MOS-SS subdomains. Conclusion: It was observed that sleep quality and quantity were negatively affected in group 1. We recommend that sleep quality and quantity should be investigated especially in BPH patients with increased PVR levels and decreased free uroflowmetry parameters.
