Abstract

Background

Helicobacter pylori (H. pylori) infection is a significant risk factor for gastric cancer. The effective implementation of strategies to mitigate gastric cancer requires widespread dissemination of information regarding H. pylori, diagnostic methods, and preventive measures. Despite the high incidence of gastric cancer, efforts to disseminate this information are lacking in Japan. Therefore, our survey aimed to evaluate H. pylori and gastric cancer awareness in Japan and identify factors associated with H. pylori knowledge, focusing on health literacy.

Materials and Methods

This nationwide cross-sectional survey was conducted online. We developed a questionnaire on H. pylori awareness and knowledge across four domains: infection risk, H. pylori-related diseases, testing and treatment, and gastric cancer-related problems. In addition, we evaluated health literacy using an established health literacy scale. Multivariable regression analysis was conducted using the H. pylori knowledge score as the dependent variable.

Results

Over half of the 3095 respondents were aware of H. pylori infection (56.4%). The overall correct response rate for the H. pylori knowledge questions was 45.7%, with varying performances across the knowledge domains: infection risk (57.3%), H. pylori-related diseases (50.9%), testing and treatment (37.5%), and gastric cancer (44.4%). The regression models identified the following factors as associated with a higher H. pylori knowledge: older age, higher health literacy scores, previous H. pylori testing, and healthcare professional status. Among participants without prior H. pylori testing, higher H. pylori knowledge scores were associated with a greater willingness to undergo H. pylori screening.

Conclusions

To our knowledge, this is the first nationwide assessment of H. pylori infection and gastric cancer awareness in Japan. Health literacy and previous H. pylori screening were significantly associated with H. pylori knowledge. The development of educational strategies for these factors may be desirable for gastric cancer prevention.

日本人群幽门螺杆菌与胃癌认知的网络调查

背景：幽门螺杆菌感染是胃癌的重要危险因素。有效实施缓解胃癌的策略需要广泛传播有关幽门螺杆菌、诊断方法和预防措施的信息。尽管胃癌的发病率很高，但在日本宣传这一信息的努力却很缺乏。因此，我们的调查旨在评估日本人对幽门螺杆菌和胃癌的认识，并确定与幽门螺杆菌知识相关的因素，重点关注健康素养。材料和方法：这项全国性的横断面调查是在线进行的。我们开发了一份关于幽门螺杆菌感染风险、幽门螺杆菌相关疾病、检测和治疗以及胃癌相关问题四个领域的意识和知识调查问卷。此外，我们使用已建立的健康素养量表评估健康素养。以幽门螺杆菌知识得分为因变量进行多变量回归分析。结果：3095名调查对象中有一半以上（56.4%）知道幽门螺杆菌感染。幽门螺杆菌知识问题的总体正确率为45.7%，在不同的知识领域表现各异：感染风险（57.3%）、幽门螺杆菌相关疾病（50.9%）、检测和治疗（37.5%）和胃癌（44.4%）。回归模型确定了以下因素与较高的幽门螺杆菌知识相关：年龄较大，较高的健康素养分数，以前的幽门螺杆菌检测和医疗保健专业地位。在之前没有进行过幽门螺杆菌检测的参与者中，幽门螺杆菌知识得分越高，接受幽门螺杆菌筛查的意愿越高。结论：据我们所知，这是日本首次在全国范围内对幽门螺杆菌感染和胃癌意识进行评估。健康素养和既往幽门螺杆菌筛查与幽门螺杆菌知识显著相关。针对这些因素的教育策略的发展可能是预防胃癌的必要条件。

期刊介绍： Helicobacter is edited by Professor David Y Graham. The editorial and peer review process is an independent process. Whenever there is a conflict of interest, the editor and editorial board will declare their interests and affiliations. Helicobacter recognises the critical role that has been established for Helicobacter pylori in peptic ulcer, gastric adenocarcinoma, and primary gastric lymphoma. As new helicobacter species are now regularly being discovered, Helicobacter covers the entire range of helicobacter research, increasing communication among the fields of gastroenterology; microbiology; vaccine development; laboratory animal science.
