Due to the growing trend of healthy eating, concerns of disordered eating patterns have increased. In particular, orthorexia has gained interest due to taking the healthy eating trend too far. As college student populations tend to have a high prevalence of disordered eating, it becomes logical to examine factors contributing to development and maintenance of these patterns. For instance, how does the college campus environment, particularly available dining options for students, affect food choices made on a daily basis? Also, how does the surrounding community and residency of the students affect these choices? This study explored these questions to determine the relationship between availability of dining options, availability of community food sources, and living situations in college students exhibiting symptoms of orthorexia. The results confirmed the assertions of other researchers that living arrangements are likely to be a considerable factor in influencing the food choices of students, as well as current and recent diet endorsement. A potential trend of correlation between completion of college-level nutrition coursework and orthorexia rates was also found. The results of this study are particularly applicable for college counseling center clinicians to aid in thorough assessment of student symptoms to ensure appropriate treatment and resources are provided for this at-risk population. Further, the results contribute to demographic and prevalence data in US college students, as well as the psychometric utility of the Eating Habits Questionnaire.
