Abstract
PURPOSE: This study sought to examine associations between meat-restricted diets and disordered eating cognitions and behaviors in a large sample of university students and assess the relationships between motivations for choosing a vegetarian or semi-vegetarian diet and eating patterns.METHODS: University students (n=1585; 60%F, 40%M, mean age 20.9) completed an online survey; students were categorized into vegetarians, semi-vegetarians, and non-vegetarians. Vegetarians and semi-vegetarians were sub-categorized into groups: those who cited weight or health among their reasons for adopting the diet and those who reported other reasons (e.g., religion). Outcomes were Eating Disorder Examination Questionnaire (EDE-Q) scores and rates of disordered eating behaviors.RESULTS: Vegetarians comprised 8.6% (32M, 104F) and semi-vegetarians comprised 3.2% (6M, 45F) of the sample; 25% of vegetarians (n=34) and 65% of semi-vegetarians (n=33) chose the diet for weight or health-related reasons. Semi-vegetarians scored the highest on measures of eating disorder cognitions and were the most likely to report engaging in disordered eating behaviors, with vegetarians at intermediate risk and non-vegetarians the least likely to report disordered cognitions or behaviors. Semi-vegetarians adopting the diet for reasons of weight or health were at especially high risk compared to other semi-vegetarians, while no associations were found between motivations for adopting a vegetarian diet and disordered eating patterns.CONCLUSION: Semi-vegetarians, especially those adopting the diet for reasons of weight or health, are more likely to exhibit disordered eating cognitions and behaviors compared to vegetarians and non-vegetarians.LEVEL OF EVIDENCE: Level III, cohort study.
