Abstract:
Objective:To analyze the infection status and influencing factors of Helicobacter pylori ( Hp) in healthy children. Methods:This is a cross-sectional study. The data of 684 children aged 3 to 14 years who underwent the 13C urea breath test in the Health Management Center of Fuwai Central China Cardiovascular Hospital from December 2022 to December 2023 were retrospectively collected, and 652 of them who met the criteria were included in the analysis. According to whether they were infected with Hp, the children were divided into the infected group and the non-infected group, and the differences in age, gender, living habits and other aspects between the two groups were compared. Multivariate logistic regression analysis was used to analyze the factors influencing Hp infection. Results:Among the 652 children, there were 134 cases in the infected group and 518 cases in the non-infected group, with an Hp infection rate of 20.6%. The Hp infection rate showed an upward tendency with age. The Hp infection rates in children aged 3 to 5 years, 6 to 11 years, and 12 to 14 years were 12.6%, 22.0%, and 25.2% respectively ( χ 2=9.862, P=0.007). Univariate analysis showed that the proportions of Hp infection were higher in children who never washed their hands, ate in school cafeterias, did not have separate meals, were fed with chewed food, bit their fingers or toys, lived with relatives who had a history of gastrointestinal diseases, had low family income, had parents with low educational level, and were mixed/artificially fed during infancy, which were 26.1%, 24.1%, 25.4%, 25.7%, 26.0%, 25.8%, 25.1%, 23.7%, and 23.6% respectively (all P<0.05). Multivariate analysis showed that separate meals, good handwashing habits, and high family income were protective factors against Hp infection ( OR=0.689, 0.779, 0.602, P=0.004, 0.013, 0.019), while feeding with chewed food was a risk factor for Hp infection ( OR=1.998, P=0.001). Conclusion:The Hp infection rate of children undergoing health examination in Zhengzhou is at low level, and the main influencing factors are separate meals, handwashing habits, feeding with chewed food, and family income.
