Nutritional knowledge and related factors among hemodialysis patients: A systematic review

This systematic review examined the nutritional knowledge and related factors among hemodialysis patients. An exhaustive and methodical exploration was conducted across various global electronic databases, including Scopus, PubMed, Web of Science, and Persian electronic databases like Iranmedex and the Scientific Information Database. This search utilized keywords derived from Medical Subject Headings, specifically “knowledge”, “hemodialysis”, and “nutrition”, spanning from the inception of these databases until March ۲۵, ۲۰۲۴. The quality of the studies incorporated into this systematic review was assessed utilizing the Appraisal tool for Cross-Sectional Studies (AXIS tool). In total, there were ۷۲۱ hemodialysis patients in eight cross-sectional studies. Among the participants, ۶۱.۷۰% were male. The participants had a mean age of ۵۵.۰۳ (standard deviation [SD]=۱۴.۰۶) years. The studies incorporated in this systematic review were conducted in various countries: the United Kingdom (n=۲), India (n=۲), Italy (n=۱), Iran (n=۱), Greece (n=۱), and a joint study from Turkey and Finland (n=۱). The nutritional knowledge among hemodialysis patients was ۴۷.۷۹ out of ۱۰۰. This score indicates a suboptimal level of knowledge in this area. Factors including education level, attitude, practice, family income per month, and diet counseling were related to the nutritional knowledge of hemodialysis patients. Consequently, policymakers and healthcare administrators can enhance the nutritional understanding of patients undergoing hemodialysis by focusing more on nutritional knowledge factors, such as education level, attitude, practice, monthly family income, and dietary counseling.
