Study Overview
=================
Brief Summary
-----------------
The first large population-based study to evaluate lower urinary tract symptoms and their impact on quality of life in night workers.

Detailed Description
-----------------
The first large population-based study to evaluate lower urinary tract symptoms (LUTS) and their impact on quality of life in night workers. The study objective is to assess the prevalence and bother of LUTS in the population of night workers. This study will be conducted as a questionnaire survey with assessment of LUTS using a standardized protocol based on definitions by the International Continence Society (ICS). The International Prostate Symptom Score (IPSS), the Overactive Bladder- Validated 8-question Screener (OAB-V8), the Patient Health Questionnaire-9 (PHQ-9), the Athen Insomnia Scale, the Work Productivity and Activity Impairment Questionnaire (WPAI), the 12-Item Short Form Health Survey (SF-12) questionnaires will be included. Participants will be also asked to rate how often they experienced individual LUTS and the degree of associated bother.
