Abstract

Objective: This systematic review was conducted to examine the impact of education on nutritional knowledge for cancer prevention using the Health Belief Model.

Methods: Comprehensive searches were performed in international electronic databases, including Scopus, PubMed, and Web of Science, from their inception until June 16, 2024. Keywords derived from Medical Subject Headings such as "Nutrition Knowledge," "Education," "Health Belief Model," and "Cancer" were utilized. Additionally, Iranian databases like Iranmedex were searched. The quality of randomized controlled trials (RCTs) and quasi-experimental studies was assessed using the Joanna Briggs Institute's (JBI) critical assessment checklist.

Results: A total of 611 participants were enrolled in five studies. Among these participants, 78.39% were female, and 76.76% were in the intervention group. The mean age of participants was 42.12 years (SD = 6.47). The mean follow-up period was approximately 14 weeks, and the average duration of the intervention was 54 minutes. The findings indicated that education based on the Health Belief Model was effective in increasing nutritional knowledge. The meta-analysis revealed a significant improvement in nutritional knowledge among participants who received HBM-based education, with a pooled SMD of 0.75 (95% CI: 0.52-0.98, p < 0.001), indicating a moderate-to-large effect size. The intervention group demonstrated increased knowledge scores compared to controls, with an average follow-up period of 14 weeks and intervention duration of approximately 54 minutes per session.

Conclusion: Health professionals, such as nurses, can utilize this model to enhance nutritional knowledge. It is recommended that health managers and policymakers create environments that enable health professionals to employ educational strategies based on the Health Belief Model, thereby improving nutritional knowledge.

基于健康信念模型的防癌营养知识教育效果的系统评价与meta分析

目的：运用健康信念模型，探讨营养知识教育对预防癌症的影响。方法：综合检索Scopus、PubMed、Web of Science等国际电子数据库，检索时间自建立之日起至2024年6月16日。使用了来自医学主题标题的关键词，如“营养知识”、“教育”、“健康信念模型”和“癌症”。此外，伊朗的数据库如Iranmedex也被搜索。随机对照试验（rct）和准实验研究的质量采用乔安娜布里格斯研究所（JBI）关键评估清单进行评估。结果：五项研究共纳入611名参与者。其中女性占78.39%，干预组占76.76%。参与者的平均年龄为42.12岁（SD = 6.47）。平均随访时间约为14周，平均干预时间为54分钟。结果表明，基于健康信念模型的教育在提高营养知识方面是有效的。荟萃分析显示，接受hbm教育的参与者在营养知识方面有显著改善，合并SMD为0.75 (95% CI: 0.52-0.98, p < 0.001)，表明有中等到较大的效应。与对照组相比，干预组表现出更高的知识得分，平均随访时间为14周，每次干预持续时间约为54分钟。结论：护士等卫生专业人员可以利用该模型提高营养知识。建议卫生管理人员和政策制定者创造环境，使卫生专业人员能够采用基于健康信念模型的教育策略，从而提高营养知识。

期刊介绍： Cancer is a very complex disease. While many aspects of carcinoge-nesis and oncogenesis are known, cancer control and prevention at the community level is however still in its infancy. Much more work needs to be done and many more steps need to be taken before effective strategies are developed. The multidisciplinary approaches and efforts to understand and control cancer in an effective and efficient manner, require highly trained scientists in all branches of the cancer sciences, from cellular and molecular aspects to patient care and palliation. The Asia Pacific Organization for Cancer Prevention (APOCP) and its official publication, the Asia Pacific Journal of Cancer Prevention (APJCP), have served the community of cancer scientists very well and intends to continue to serve in this capacity to the best of its abilities. One of the objectives of the APOCP is to provide all relevant and current scientific information on the whole spectrum of cancer sciences. They aim to do this by providing a forum for communication and propagation of original and innovative research findings that have relevance to understanding the etiology, progression, treatment, and survival of patients, through their journal. The APJCP with its distinguished, diverse, and Asia-wide team of editors, reviewers, and readers, ensure the highest standards of research communication within the cancer sciences community across Asia as well as globally. The APJCP publishes original research results under the following categories: -Epidemiology, detection and screening. -Cellular research and bio-markers. -Identification of bio-targets and agents with novel mechanisms of action. -Optimal clinical use of existing anti-cancer agents, including combination therapies. -Radiation and surgery. -Palliative care. -Patient adherence, quality of life, satisfaction. -Health economic evaluations.
