ABSTRACT

Background:Understanding the local epidemiologic features of Helicobacter pylori (Hp)infection might be helpful for formulating a targeted disease control strategy. Aims:To study the current status of Hp infection and its influencing factors in health examination subjects and outpatients in Xiuzhou District,Jiaxing,Zhejiang Province. Methods:Local residents who visited the health examination center or outpatient service for Hp test from Jan. 2016 to Jun. 2017 at Zhejiang Shin-an International Hospital were enrolled. Demographic data,life style,dietary habit,drug history and history of gastroscopy and dental treatment were collected to analyze the influencing factors of Hp infection. Positive for any of the three Hp tests13 C/ 14C-UBT,biopsy pathology and bacterial culture was defined as Hp infection. Results:A total of 4 220 adults, including 2 002 males and 2 218 females with age ranged from 18 to 80 years were enrolled. The overall detection rate of Hp infection was 38. 1%. The detection rate in males was significantly higher than that in females (45. 0% vs. 32. 0%, P＜0. 05). Also,the detection rate of middle-aged subjects (41-65 years)was significantly higher than those of young (18-40 years)and elderly subjects (66-80 years)(45. 0% vs. 31. 2% and 32. 0%,P ＜0. 05). Cigarette smoking, alcohol drinking,as well as dinner party were associated with higher detection rate of Hp infection (P＜0. 05),while long-term use of non-steroidal anti-inflammatory drugs (NSAIDs)was associated with lower Hp detection rate (P＜0. 05). No associations were found between gastroscopic procedure and dental treatment with the detection rate of Hp infection (P＞0. 05). Conclusions:The detection rate of Hp infection in health examination subjects and outpatients in Xiuzhou District, Jiaxing,Zhejiang Province is relatively low when compared with the mean level in general population. Unhealthy life style is associated with the increased risk of Hp infection.
