目的了解广东农村居民消化不良与幽门螺杆菌的关系。方法采用随机整体抽样方法，在广东５个市各选择一个自然村的２０岁以上的常住居民５８７人进行问卷调查，并收集血清标本以检测血清抗Ｈｐ－ＩｇＧ抗体。结果广东农村居民消化不良发病率为３６．８％，男性为３６．６％，女性为３７．０％，两性间发病率比较差异无显著性（Ｐ＞０．０５）。在被调查的５个地区消化不良人群中，有５６．５％的人群Ｈｐ血清学阳性，而在无消化不良的人群中有５２ ３％阳性，两组人群阳性率比较差异无显著性（Ｐ＞０．０５）；消化不良人群Ｈｐ血清学阳性率与总体人群比较（５６．５％ｖｓ５３．８％）差异亦无显著性（Ｐ＞０．０５）。结论广东农村居民消化不良与幽门螺杆菌无明确关系。
Objective To understand the relationship between indigestion and Helicobacter pylori in Guangdong rural residents. Methods A total sample of 587 permanent residents over the age of 20 in 5 villages in 5 cities of Guangdong Province were surveyed by random sampling method. Serum samples were collected to detect serum anti-Hp-IgG antibody. Results The prevalence of dyspepsia in rural residents in Guangdong was 36.8%, 36.6% for males and 37.0% for females. There was no significant difference in the incidence of malabsorption between the two sexes (P> 0.05). Among the five digestive disorders surveyed, 56.5% of the population were positive for Hp seropositivity while 52.3% were positive in the non-digestible population, with no significant difference between the two groups (P > 0.05). The positive rate of Hp seropositivity in dyspepsia patients was also not significantly different from the general population (56.5% vs53.8%) (P> 0.05). Conclusion Guangdong rural residents with dyspepsia and Helicobacter pylori no clear relationship.
