Health literacy has been recognized as a significant social determinant of health, defined as the ability to access, understand, appraise, and apply health-related information across healthcare, disease prevention, and health promotion. This systematic review aims to understand the relationship between health literacy, blood pressure, and dietary salt intake. A web-based search of PubMed, Web of Science, CINAHL, ProQuest, Scopus, Cochrane Library, and Prospero was performed using specified search/MESH terms and keywords. Two reviewers independently performed the data extraction and analysis, cross-checked, reviewed, and resolved any discrepancies by the third reviewer. Twenty out of twenty-two studies met the inclusion criteria and were rated as good quality papers and used in the final analysis. Higher health literacy had shown to have better blood pressure or hypertension knowledge. However, the relationship between health literacy with dietary salt intake has shown mixed and inconsistent findings. Studies looking into the main four domains of health literacy are still limited. More research exploring the links between health literacy, blood pressure, and dietary salt intake in the community is warranted. Using appropriate and consistent health literacy tools to evaluate the effectiveness of salt reduction as health promotion programs is required.
健康素养已被公认为健康的重要社会决定因素，定义为在医疗保健、疾病预防和健康促进中获取、理解、评估和应用与健康相关信息的能力。本系统评价旨在了解健康素养、血压和膳食盐摄入量之间的关系。使用特定的搜索词和关键词，在 PubMed、Web of Science、CINAHL、ProQuest、Scopus、Cochrane Library 和 Prospero 上进行了基于网络的搜索。两位评审员独立进行了数据提取和分析，交叉核对、评审并由第三位评审员解决任何差异。22 项研究中有 20 项符合纳入标准，并被评为高质量论文，用于最终分析。较高的健康素养与更好的血压或高血压知识相关。然而，健康素养与膳食盐摄入量之间的关系存在不一致的发现。研究健康素养的四个主要领域的研究仍然有限。需要更多的研究来探索社区中健康素养、血压和膳食盐摄入量之间的联系。需要使用适当和一致的健康素养工具来评估盐减少作为健康促进计划的有效性。
