Lifetime prevalence rates in Te Rau Hinengaro (The New Zealand Mental Health Survey) suggest eating disorders are at least as common in the Māori population as the non-Māori population, yet little is known at a population level about those accessing specialist mental health treatment for eating disorders in New Zealand. The aim of this study was to describe the population undergoing specialist mental health treatment for eating disorders and compare Māori and non-Māori clinical characteristics and service use.
