Abstract Background  Working environment such as psychosocial factors impacts the health of workers. However, few studies have assessed the association of work-related factors with the prevalence of peptic ulcer disease (PUD) in large population based study. Methods  After exclusion of military personnel, 16,099 wage workers (20 ≤ age ≤ 65 years) from the Fourth Korea National Health and Nutrition Examination Survey (2008–2011) were included in this study. Job status was defined as the place of employment of longest duration. To evaluate the working environment, we used a comprehensive work-stressor measure. Univariate and multivariable regression analyses were performed to assess the effect of occupation type on the prevalence of PUD. Results  Among the subjects, 5540, 3398, and 7161 were white-, pink-, and blue-collar workers, respectively. The prevalence of PUD was highest among blue-collar workers (n = 336, 7.1%), followed by pink-collar (n = 116, 5.1%) and white-collar (n = 180, 4.9%) workers. In the multivariable analysis, work type and uncomfortable gestures were independently associated with the risk of PUD. Compared with office workers, operators in industrial plants and machine operators had a significantly higher prevalence of PUD (odds ratio, 1.9; 95% confidence interval, 1.1–3.3) after adjusting for age, socioeconomic factors, sex, smoking, alcohol consumption, daily exercise, sleep duration, and working conditions. Discussion  In conclusion, work-related factors, particularly blue-collar work and uncomfortable job gestures, are independently associated with the risk of PUD. Therefore, it is important to monitor the development of PUD in workers exposed to these factors. Keywords  Peptic ulcer disease · Occupations · Health surveys · Prevalence

Introduction Although the prevalence of peptic ulcer disease (PUD) has decreased worldwide, its management is hampered by the increasing frequency of idiopathic PUD, i.e., not associated with Helicobacter pylori infection or non-steroidal antiinflammatory drugs (Kanno et al. 2015, 2016; Lanas and Chan 2017). Indeed, 5–20% of cases of PUD are classified as idiopathic (Deding et al. 2016). As well as the major risk * Dong Kyun Park [email protected] 1

factors, other variables related to PUD have been investigated (Furuse et al. 1999; Theorell et al. 2016). Since majority of the workers have spent their life time in working place, the working environment has influenced the physical and psychologica
