摘要
Background: Orthorexia Nervosa (ON) is an unhealthy obsession wit "proper", "clean", or "healthful" eating that can potentially lead to serious physical, psychological, and social impairments. Aim: We aimed to examine associations between level of interest in nutrition, knowledge of nutrition, and prevalence of orthorexia traits in a population of college students enrolled in a general education nutrition course. Methods: Of the 579 students enrolled in the class during Spring semester of 2018, 221 (38%) completed an online survey. The survey was completed during weeks 8-9 of the 15-week semester. Results: The average nutrition knowledge score was 8.7 out of 12 (standard deviation (SD) 1.4, range 0-12). The average of the summed 29 orthorexia traits was 63.4 (SD 12.4; range=41-102); lower scores indicated less agreeance with practicing ON behaviors. The degree of interest in the subject of nutrition was positively associated with prevalence of orthorexia traits (r=0.43, p<0.0001), but not nutrition knowledge (p>0.05). Nutrition knowledge was inversely associated with prevalence of orthorexia traits (r=-0.19, p=0.005). No associations were found between age, sex, year in school, or BMI and orthorexia traits. Conclusions: Interest in nutrition is associated with increased prevalence of orthorexia traits, however, higher levels of nutrition knowledge are associated with decreased prevalence of orthorexia traits. Additional studies should further examine these associations in prospective studies of nutrition/dietetics students as they progress in their programs and gain additional knowledge of nutrition.
