Background In many countries, doctors are recommended to provide nutrition care to patients to improve the dietary behaviours of individuals and populations. Here, we present a systematic review that aims to critically synthesise literature on nutrition education provided to medical students.Methods In this systematic review, a literature search was done between May 1 and July 1, 2018, for articles on medical students' nutrition knowledge, skills, and confidence to counsel patients, from Nov 1, 2012, to Dec 31, 2018. Search terms related to medical students included "nutrition in medical education", "medical nutrition education", and "undergraduate medical nutrition education". Search terms for topic of interest included "nutrition", "knowledge", "skills", "nutrition counselling", "confidence", "nutrition care", or "nutrition education". Included studies examined any aspect of recently graduated (ie, ≤4 years) or current medical students' nutrition knowledge, attitudes, skills, or confidence (or all three) in nutrition or nutrition counselling; evaluated nutrition curriculum initiatives for medical students; or assessed recently graduated or current medical students' perceptions of nutrition education. Quality assessment appraisal of the studies was done using a Mixed Methods Appraisal Tool. Curriculum initiatives were also appraised.Findings 66 studies were identified by the search and 24 were eligible for full-text analysis. 16 quantitative studies, three qualitative studies, and five curriculum initiatives from the USA (n=11), Europe (n=4), the Middle East (n=1), Africa (n=1), and Australasia (n=7) met the inclusion criteria. Our analysis of these studies showed that nutrition is insufficiently incorporated into medical education, regardless of country, setting, or year of medical education. Deficits in nutrition education affect students' knowledge, skills, and confidence to implement nutrition care into patient care. A modest positive effect was reported from curriculum initiatives.Interpretation Despite the centrality of nutrition to healthy lifestyle, medical students are not supported to provide high-quality, effective nutrition care. Medical education can be enhanced by institutional commitment to make nutrition education compulsory in medical training, establishment of nutrition competencies to provide a benchmark for nutrition knowledge and skills to be included in curricula, and supported by funding for innovative curriculum initiatives. These initiatives will improve nutrition in medical training to support future doctors for the 21st century.

Many GPs are interested in nutrition and would benefit from educational programmes that improve their competence to provide nutrition care. Professional development opportunities should focus on the identification of nutritional risk and the promotion of healthy dietary behaviours within the time constraints of a standard consultation.

Throughout the world, medical students and doctors report inadequate nutrition education and subsequently lack of knowledge, attitude, and skills to include nutrition in patient care. This study described New Zealand’s students’ attitudes to and self-perceived skills in providing nutrition care in practice as well as perceived quantity and quality of nutrition education received in training. 183 medical students from New Zealand’s largest medical school (response rate 52%) completed a 65-item questionnaire, partially validated, using 5-point Likert scales. Students believed incorporating nutrition care into practice is important, yet they were less confident patients improve nutrition behaviours after receiving this care. Students were confident in skills related to nutrition in health and disease but less confident in skills related to general food knowledge. Greater quantity and quality of nutrition education received was associated with greater self-perceived skills in providing nutrition care to patients but not with attitudes towards incorporating nutrition care into practice. This cohort of New Zealand medical students places similarly high importance on nutrition care as students and doctors from other countries. Further investigations beyond graduation are required to inform whether additional nutrition education is warranted for these doctors.

AimTo assess nutrition curriculum guidelines for undergraduate medical education in the United States, Canada, the United Kingdom, Republic of Ireland, Australia, and New Zealand to highlight potential opportunities for shared learning on the advancement of nutrition in medical education.MethodsA comprehensive list of professional bodies, councils, organizations, and other groups relevant to education or nutrition was compiled for each country after a review of relevant white and gray literature. All documents that were published from 2000 onwards, and that provided guidance on nutrition education within undergraduate medical education for one of the identified countries were included in the review. Each curriculum guideline was evaluated for 1) the organization’s or group’s role in undergraduate medical education; 2) the extent of nutrition-related recommendations; and 3) mandatory implementation.ResultsIn the countries reviewed, a total of six nutrition-related curriculum guidelines were identified. All countries, aside from the Republic of Ireland, currently have externally visible curriculum guidelines to inform medical schools in undergraduate nutrition education, yet there is little evidence of mandatory enforcement. Curriculum guidelines predominantly focus on basic nutrition principles, nutrition assessment, the role of nutrition in health, interdisciplinary teamwork, and the provision of nutrition counseling. Notable differences exist regarding the scope and detail of curriculum guidelines for the reviewed countries.ConclusionThere are promising developments in nutrition curriculum guidelines for medical schools within the reviewed countries. Differences in the scope and detail of nutrition curriculum guidelines may influence the nutrition education provided to medical students, and the subsequent nutrition care provided by doctors in these countries. Consideration is required as to how to monitor and evaluate the nutrition competence of doctors in relation to routine health care practices, as well as the impact of their competency levels on patients’ nutrition behavior and health outcomes.

INTRODUCTION: Improvements in individuals' nutrition behaviour can improve risk factors and outcomes associated with lifestyle-related chronic diseases. AIM: This study describes and compares New Zealand medical students, general practice registrars and general practitioners' (GPs') attitudes towards incorporating nutrition care into practice, and self-perceived skills in providing nutrition care. METHODS: A total of 183 New Zealand medical students, 51 general practice registrars and 57 GPs completed a 60-item questionnaire investigating attitudes towards incorporating nutrition care into practice and self-perceived skills in providing nutrition care. Items were scored using a 5-point Likert scale. Factor analysis was conducted to group questionnaire items and a generalised linear model compared differences between medical students, general practice registrars and GPs. RESULTS: All groups indicated that incorporating nutrition care into practice is important. GPs displayed more positive attitudes than students towards incorporating nutrition in routine care (p<0.0001) and performing nutrition recommendations (p<0.0001). General practice registrars were more positive than students towards performing nutrition recommendations (p=0.004), specified practices (p=0.037), and eliciting behaviour change (p=0.024). All groups displayed moderate confidence towards providing nutrition care. GPs were more confident than students in areas relating to wellness and disease (p<0.0001); macronutrients (p=0.030); micronutrients (p=0.010); and women, infants and children (p<0.0001). DISCUSSION: New Zealand medical students, general practice registrars and GPs have positive attitudes and moderate confidence towards incorporating nutrition care into practice. It is possible that GPs' experience providing nutrition care contributes to greater confidence. Strategies to facilitate medical students developing confidence in providing nutrition care are warranted.
