Abstract: Extensive knowledge on nutrition and dieting has been associated with an increased risk of orthorexia (an obsession with food that one considers healthy) within the research literature. A systematic review was conducted to identify the prevalence of orthorexia in individuals who were employed in, or studying, health careers. The databases Psychinfo and Pubmed were searched to obtain research articles. Studies assessing orthorexia and either students or workers within health-related fields were included. A study merit rating system was utilised to assess the quality of each study included. In total, 26 articles were included in the current review after applying inclusion and exclusion criteria. The prevalence of orthorexia was the greatest in dietetic students. Research findings consistently demonstrated that the prevalence of orthorexia was higher in those working or studying in health fields than the general population. Individuals in their early stages of study or career appear most at risk. Orthorexia prevalence, however, does not appear to differ by sex or BMI. Orthorexia is novel research area. The trends in the current review suggest that individuals in health-related careers appear to be more at risk of orthorexic patterns. More research in this area is needed through the use of scales with greater psychometric properties.
