Abstract:
Objective:To investigate the characteristics of Helicobacter pylori(Hp)infection in community patients. Methods:In July 2020,Three hundred and sixty outpatients with Hp infection confirmed by 14C breath test from August 2018 to July 2019 in Pengpuxincun community health service center of Jing′an District of Shanghai were selected by simple random sampling for a questionnaire survey. The contents of the questionnaire included general information, symptoms of digestive tract, awareness of disease hazards, frequency of dining out, Hp infection in family members. A total of 335 valid questionnaires were collected with a response rate of 93.06% (335/360). Results:Among 335 cases of Hp infection, 282 cases had clinical symptoms and 53 cases had no clinical symptoms. The infection rate of family members of Hp infected patients with and without clinical symptoms was 55.67% (157/282) and 56.60% (30/53) respectively (χ2=0.016, P>0.05). Belching was the most common symptom(27.09%,175/646), followed by abdominal distension(22.45%,145/646), acid reflux (17.03%,110/646), abdominal pain(14.86%), halitosis(14.55%). There was no significant difference in the frequency of halitosis, acid regurgitation, belching, abdominal distension and abdominal pain among the three groups(χ2=13.297, P>0.05). The Hp infection rate of family members with frequent or seldom out dining was 82.40% (103/125) and 40.00% (84/210), respectively, (χ2=57.122, P<0.05). The awareness rates of Hp hazard in patients with educational levels of primary school and below, junior high school, senior high school and junior college and above were 9.43% (5/53), 51.55% (50/97), 62.50% (65/104) and 87.65% (71/81), respectively(χ2=82.447, P<0.01). There was no significant difference in the age distribution between males and females (χ2=1.155, P>0.05). Conclusion:It is necessary to strengthen the health management of Hp infected people and improve the awareness of Hp infection hazards among community residents to reduce Hp infection rate in the community.
