ABSTRACT:
Poor nutritional status is a key contributor to tuberculosis (TB) susceptibility and poor treatment outcomes. However, the role of nutrition-related knowledge, attitudes, and practices (KAP) remains unclear in Sub-Saharan Africa. This scoping review maps the existing evidence on the association between nutritional status and nutrition-related KAPs among people receiving TB treatment in Sub-Saharan Africa. Following the framework outlined by Arksey and O’Malley, we conducted a comprehensive literature search using South African ePublications, MEDLINE, PubMed, and Web of Science databases. Of 1890 articles identified, 17 articles were included in the study after screening titles, abstracts, and full texts. The emerging themes from the included studies were nutritional outcomes, dietary behaviour and practices, nutrition-related knowledge, barriers and facilitators to optimal nutrition, and implementation of strategic recommendations for nutrition support in TB management. Undernutrition, low dietary diversity, and food insecurity were prevalent among TB patients. Socioeconomic and health system factors limited optimal nutrition. Nutrition-related KAPs were not directly assessed in most studies, indicating a gap in the evidence. Effective TB management in Sub-Saharan Africa requires the integrated nutrition support, patient-centred education, and context-specific interventions to improve treatment outcomes.
