Abstract: Objective To investigate the prevalence of Helicobacter pylori (Hp) infection and its influencing factors among physical examinees in Pinggu District of Beijing. Methods Health examinees from a hospital in Pinggu District of Beijing from January 2019 to December 2021 were selected to analyze the Hp infection status. Univariate and multivariate analysis methods were used to analyze the influencing factors of Hp infection. Results In this study, 9 286 physical examinees were included, and 3 158 cases of Hp infection were detected, accounting for 34.01%。 Multivariate Logistic regression analysis showed that men (OR=1.163), drinking (OR=2.667), eating out (OR=2.866), spicy food (OR=3.887), pickled food (OR=5.283), take‐out food (OR=2.719), Hp infection in family members (OR=4.825), history of digestive system diseases (OR=2.552), insistence on using public chopsticks (OR=0.229), and knowledge of Hp (OR=0.338) were the influencing factors of Hp infection in the physical examinees in Pinggu District, Beijing. Conclusions The Hp infection rate of the physical examinees in Pinggu District of Beijing is lower than the national average, which is closely related to factors such as drinking, eating out, bad eating habits, and Hp infection of family members. Prevention measures can be formulated by changing unhealthy lifestyles and eating habits, and Hp related health knowledge can effectively reduce and avoid Hp infection。
