Nutrition and mental health research in Australia and New Zealand: A review of progress and directions for the future

This review summarises nutrition and mental health research in Australia and New Zealand between 1986 and 2006. The method used to identify papers for inclusion was a search of computerised databases: Medline, Cinahl and Meditext 1986-2006, with subsequent bibliographical review. Key search words were nutrition, diet, mental disorder, mental illness, weight, physical health, Australia and New Zealand. Inclusion criteria included: English language, original data in peer reviewed journals, and examination of some component of nutrition in people with a mental illness. The review of thirteen papers found that the evidence base for dietetic practice in mental health has developed through small assessment and interventional research, often with multidisciplinary collaboration. Future research should include quality and outcome measures with intersectoral partnerships. Dietitians are well positioned to lead and participate in mental health research and to implement research findings to improve the nutritional status of this vulnerable group.
