Abstract
Background: Helicobacter pylori infection is very common worldwide.
Aim: To evaluate the prevalence and identify the risk factors for Helicobacter pylori infection in Chinese maritime workers.
Subjects and methods: Between March 2010 and October 2010, 3995 subjects were selected in the Hospital of Dalian Port. The presence of Helicobacter pylori infection was confirmed using laboratory tests (serum IgG anti-Helicobacter pylori antibodies) and background information, family history, lifestyle and eating habits were collected using questionnaires.
Results: The prevalence of Helicobacter pylori infection was 44.9% in these Chinese maritime workers. Prevalence of Helicobacter pylori infection was associated with family income, living space, family history of gastrointestinal diseases, smoking, drinking tea, raw vegetables consumption, spicy food, pickle food, dining outside, no regular meal and dish sharing. Further analysis with multivariate logistic regression analysis indicated that raw vegetables consumption, pickle food consumption, family income and family history of gastrointestinal diseases were independent predictors for Helicobacter pylori infection. No association was found between infection and gender, marital status, education, alcohol consumption and tap water consumption.
Conclusion: Helicobacter pylori infection is associated with raw vegetables consumption, pickle food consumption, family income and family history of gastrointestinal disease among Chinese maritime workers.
