Longitudinal analysis of factors related to Helicobacter pylori infection in Chinese adults

Abstract

This research aimed to analyze lifestyle-related factors which influence Helicobacter pylori (Hp) infection and outcomes in Chinese adults. A single-center, retrospective study was performed from January 2012 to December 2020. Self-administered questionnaires were used to collect relevant lifestyle information, and the 13C-urea breath test was used to diagnose active Hp infection. A total of 18,211 subjects were enrolled in the study, of which 5,511 were females (30.26%). Subjects were studied longitudinally for up to five follow-up visits. At baseline, gastric Hp test was negative in 10,670 subjects (58.59%) and positive in 7,541 subjects (41.41%). Males exhibited a significantly higher Hp infection rate than females (38.56% vs 2.65%, respectively; χ 2 = 26.45, P < 0.001). Throughout the course of follow-up, Hp positive rates in the subjects decreased ( χ trend 2 {\chi }_{\text{trend}}^{2} = 666.04, P < 0.001). Among the subjects with baseline negative results, 3–6% changed from negative to positive during follow-up. In contrast, among those with baseline positive results, >70% remained positive, and 21–26% changed from positive to negative. However, only 22–27% of Hp-infected subjects received pharmacotherapy. The results indicate the prevalence of Hp infection is high in the Chinese population. That additional effort is required to prevent and control Hp infection.

Study of Helicobacter pylori infection in patients with chronic atrophic gastritis and its relationship with lifestyle habits and dietary nutrient intake: A retrospective analysis

“…This compromises the protective barrier of the mucosa and makes it more susceptible to Hp invasion. [ 22 ] The choice of dining location may also be related to food hygiene. Dining at external establishments with inadequate utensil disinfection and crowded eating environments align closely with the transmission routes of Hp in the digestive system, thus increasing the risk of Hp infection.…”
