There is a lack of reports on the awareness of Helicobacter pylori (H pylori) prevention and treatment in the general Chinese population. And whether the knowledge level will affect their action toward screening was unknown. This study aimed to conduct a national survey on the knowledge, attitudes, and practice regarding H pylori infection in Chinese physicians and the public.
This was an Internet-based survey of the general Chinese population and Chinese physicians from different specialties, carried out from January to February 2019. Both surveys (general population's and physicians') included questions to assess the knowledge and attitudes toward H pylori and its action.
A total of 3211 people and 546 physicians were enrolled. In the population, the proportion of subjects who answered correctly to all questions about H pylori's infectivity was only 16%, and that for H pylori's harmfulness and that for H pylori preventive measures were 35% and 43.6%, respectively. In general, physicians had a better understanding of H pylori's harmfulness (83.9%) than the other population. The vast majority of the surveyed population (87.0%) and physicians (82.2%) supported a national H pylori screening plan to prevent gastric cancer. The support ratio paralleled with the overall knowledge level. Unexpectedly, gastroenterologists tend to have a relatively low support rate for H pylori screening than non-gastroenterologists (58.2% vs 84.2%, P < .001), which may be related to consideration of heavy medical burden (67.3%).
The general population in China has relatively insufficient awareness of H pylori, which is incompatible with the highly infectious status. More works on health education are needed to improve the knowledge of this gastric pathogen.
目前缺乏中国普通人群对幽门螺杆菌（H.pylori）预防和治疗意识的报告，且其知识水平是否会影响他们进行筛查的行为尚不清楚。本研究旨在对中国医生和公众中 H.pylori 感染的知识、态度和实践进行全国性调查。
这是一项针对中国普通人群和不同专科医生的基于互联网的调查，于 2019 年 1 月至 2 月进行。两个调查（普通人群和医生）都包括评估 H.pylori 及其行为的知识和态度的问题。
共纳入 3211 名普通人群和 546 名医生。在人群中，回答所有关于 H.pylori 传染性问题的正确比例仅为 16%，回答 H.pylori 危害性和 H.pylori 预防措施的正确比例分别为 35%和 43.6%。总体而言，医生对 H.pylori 的危害性的了解优于其他人群（83.9%）。绝大多数被调查人群（87.0%）和医生（82.2%）支持全国性的 H.pylori 筛查计划以预防胃癌。支持率与总体知识水平平行。出乎意料的是，与非胃肠病学医生相比，胃肠病学家对 H.pylori 筛查的支持率相对较低（58.2%比 84.2%，P<.001），这可能与考虑到沉重的医疗负担（67.3%）有关。
中国普通人群对 H.pylori 的认识相对不足，与高传染性状态不相符。需要开展更多的健康教育工作，以提高对这种胃病原体的认识。
