||Shift work increases the frequency of duodenal ulcer in H. pylori infected workers
||Nov. 2006, Vol.63, No.11, p.773-775. 12 ref.
||The objective of this study was to evaluate whether shift work is associated with an increased rate of peptic ulcer in H. pylori infected workers. During a two year period, workers with persistent dyspeptic symptoms underwent non-invasive evaluation of H. pylori status. The workers testing positive were included in the study and divided into 247 day workers and 101 shift workers. In all workers, a gastrointestinal endoscopy was performed and biopsy specimens were taken from the stomach. It was found that the prevalence of duodenal ulcer was significantly higher in shift workers than in day-time workers (odds ratio OR=3.92) and persisted after multivariate analysis, taking into account possible confounding factors (OR=3.96). It is concluded that shift work increases the ulcerogenic potential of H. pylori infection and should be considered a risk factor for duodenal ulcer in infected shift workers.
