Current Status of Helicobacter pylori Infection and Associated Factors among the Dong Ethnic Population in Xinhuang County
Objective: This study examined the current status of Helicobacter pylori (H. pylori) infection among the Dong population in Xinhuang Dong Autonomous County. It also identified factors associated with infection to inform targeted prevention and control strategies. Methods: This retrospective study enrolled outpatients and health-checkup attendees who underwent a ¹⁴C-urea breath test at Xinhuang County People’s Hospital between January 2024 and January 2025. Infection status was determined by the breath test, and demographic, dietary, and lifestyle data were collected from the hospital information management system and a standardized questionnaire. Univariate χ² tests and multivariable logistic regression were used to assess factors associated with infection. Results: Among 1,052 Dong residents of Xinhuang County, the overall H. pylori infection rate was 34.22%. Education at high school level or below, employment outside the public institutional system, smoking, and alcohol consumption were independent risk factors. A history of chronic disease and regular consumption of black oil tea were protective factors. Conclusion: The H. pylori infection rate among the Dong population in Xinhuang County is relatively low. The mechanism behind the apparent protective effect of black oil tea remains unclear. Prospective studies of its components are warranted to clarify this effect and to expand the options for treating H. pylori infection.
