Irritable Bowel Syndrome prevalence and work ability in a sample of healthcare workers exposed to occupational stress

Objective: Occupational stress represents a significant precipitating factor in different diseases but its role in Irritable Bowel Syndrome (IBS) needs to be clarified. The present cross-sectional study aimed at investigating the prevalence of IBS diagnosis in a sample of health workers and exploring the potential relationships between IBS, work-related stress levels and work ability. Methods: 653 health workers undergoing periodical occupational health surveillance at the Occupational and Preventive Medicine Unit of a major University Hospital in central Italy, were consecutively recruited and screened for IBS diagnosis, according to ROMA IV criteria. The rating scales IBS Severity Scoring System (IBS-SSS), Demand–Control–Support Questionnaire (DCSQ) and Work Ability Index (WAI) were used to assess respectively IBS severity, occupational stress and work ability levels. Results: IBS prevalence in the sample was 16.8%. Participants suffering from IBS were characterized by a higher prevalence of psychiatric diagnosis and sleep disturbances, higher levels of job strain and isostrain as well as by lower levels of work ability compared to non affected subjects. Moreover, the severity of IBS correlated positively with occupational stress and both were negatively associated with work ability. Conclusions: The present results suggest the need for preventive, organizational and management strategies at workplace aimed at protecting the health and well-being but also productivity of the worker with IBS.
