ABSTRACT

Objective To investigate Helicobacter pylori (HP) infection status and influencing factors of electrical power system employees in Shanghai. Methods A total of 29 986 employees in Shanghai electrical power system who underwent physical examination were selected as the research subjects, and received 13C-urea breath test (13C-UBT). The HP infection rate was recorded. Data including gender, age, body mass index, smoking history, drinking history, medication history, educational level, consumption of high-salt and high-fat food, presence of vomiting, and awareness of HP infection related treatment were also collected. The relationship between these factors and HP infection was analyzed. Results 13C-UBT showed that of 29,986 subjects examined, 17 580 were HP positive, and the positive rate was 58.63%. There was significant difference in HP infection rate between men and women (P 0.05). Logistic regression analysis showed that male, ignorance of HP infection related treatment, smoking and history of family HP infection were independent influencing factors for HP infection. Conclusion The HP infection rate was relatively high among employees in Shanghai electrical power system, and the main influencing factors of HP infection were male, ignorance of HP infection related treatment, smoking and history of HP family infection.
