摘要
目的了解南京市鼓楼区中老年居民幽门螺杆菌(HP)感染现状及其危险因素,为制定正确有效的预防措施提供依据。方法 2017年5~8月对南京市鼓楼区935例居民进行尿素14 C呼气试验测定,分析其感染率;同时应用调查问卷开展危险因素调查,采用单因素和多因素logistic回归分析幽门螺杆菌相关危险因素。结果 935例居民中366例(39.14%)HP阳性;单因素logistic回归分析显示有消化道疾病史、消化道不适、是否吃辛辣和方便食品与HP感染有关(P<0.05);多因素logistic回归模型拟合发现消化道疾病史与HP感染负相关,而吃辛辣和方便食品与HP感染正相关(P<0.05)。结论南京市鼓楼区居民幽门螺杆菌感染率较全国水平低,但感染仍普遍存在,应加强对消化道疾病的筛查与治疗,大力宣传健康安全的饮食习惯,积极预防幽门螺杆菌感染与传播。
Objective To understand the current status of Helicobacter pylori(HP)infection among middleaged and elderly residents in Gulou district of Nanjing,to analyze the risk factors and to provide bases for making proper and effective preventive measures. Methods A questionnaire survey was conducted among 935 residents in Gulou district and 14 C urea breath test(14 C-UBT)was performed for H.Pylori infection from May to August in 2017,Risk factors were analyzed using univariate and multivariate logistic regression. Results Among 935 residents,366 were positive for HP with the infection rate of 39.14%.A single-factor logistic regression analysis showed that history of gastrointestinal diseases,digestive tract discomfort,spicy food and ready-to-eat food were major factors associated with HP infection(P<0.05).A multivariate logistic regression fitting model analysis revealed that the history of gastrointestinal disease was negatively associated with HP infection,while spicy foods and ready-to-eat foods were positively associated with HP infection(P<0.05). Conclusions Even though the prevalence of H.pylori among middle-aged and elderly residents in Gulou district of Nanjing is lower than that of the national average.The infection is still widespread.It is necessary to strengthen the screening and treatment of digestive diseases,vigorously promote healthy and safe eating habits,and actively prevent H.pylori infection and bacteria spreading.
