Background: Malnutrition causes problems in Vietnam, including illnesses with physiological and psychological complications. The aim of this study was to describe nursing students' experiences with malnutrition at one hospital in Vietnam. Methods: Interviews of eight nursing students were performed, and the results were analysed by qualitative content analysis. Findings: The results are presented in one category (working through others) and three subcategories (awareness of malnutrition, developing family-centered care and developing health promotion). Conclusion: This study highlights the use of guidelines in collaboration (between staff and patients' relatives) to facilitate early identification and/or prevent malnutrition by improving self-care, as supported through nursing activities using family-centred care as well as teamwork.
