Association of occupational exposures and work characteristics with the occurrence of gastrointestinal disorders.

Background: Work is a daily activity with various conditions, exposures, and habits that may affect health either positively or negatively. Aim of this study was to investigate the relationship between occupational factors and conditions, and the occurrence of gastrointestinal disorders.

Methods: We enrolled in this study a sample of 891 consecutive individuals, who were examined by standard colonoscopy and gastroscopy and interviewed regarding their working conditions and exposures. Consecutively, data were statistically analyzed to explore possible associations.

Results: Peptic ulcer diagnosis was associated with reports of muscle pain/headache [odds ratio (OR): 3.656, 95 % confidence interval (95% CI): 1.898-7.043], with working in shifts (OR: 2.463, 95% CI: 1.058-5.731), and with the presence of occupational stress (OR: 2.283, 95% CI: 1.162-4.486). Gastritis was associated with muscle pain/headache (OR: 2.258, 95% CI: 1.096-4.652), shift work (OR: 3.535, 95% CI: 1.345-9.29), occupational stress (OR: 2.182, 95% CI: 1.072-4.444), and sedentary work (OR 0.275 lower risk 95% CI: 0.113-0.671). Ulcerative colitis was associated with muscle pain/headache (OR: 6.211, 95% CI: 2.162-17.840) and occupational stress (OR: 6.418, 95% CI: 2.243-18.361), while Crohn's disease diagnosis with muscle pain/headache (OR: 3.554, 95% CI: 1.628-7.759), frequent ordering food at work (OR: 4.928, 95% CI: 2.3-10.559), occupational stress (OR: 3.023, 95% CI: 1.413-6.469), work with intense physical activity (OR: 0.665 lower risk, 95% CI: 0.252-0.758). Colon cancer diagnosis was associated with frequent ordering food at work (OR: 2.739, 95% CI: 1.268-5.916) and occupational stress (OR: 3.175, 95% CI: 1.384-7.286), while stomach cancer diagnosis with ordering food at work (OR: 2.794, 95% CI: 1.154-6.763) and exposure to dust (OR: 5.650, 95% CI: 1.551-20.582). Finally, presence of polyps was associated with ordering food at work (OR: 2.154, 95% CI: 1.135-4.091), and constipation with ordering food at work (OR: 2.869, 95% CI: 1.451-5.672), occupational stress (OR: 2.112, 95% CI: 1.097-4.066), and occupational noise (OR: 0.248, 95% CI: 0.084-0.737).

Conclusion: The incidence of the gastrointestinal diseases is affected by occupational exposures and related lifestyle habits. HIPPOKRATIA 2017, 21(2): 74-79.
