ABSTRACT
BACKGROUND:
Orthorexia nervosa (OrNe) is a pattern of disordered eating behavior characterized by excessive preoccupation with overvalued ideas about healthy eating. Healthy orthorexia (HeOr) refers to a non-pathological interest in healthy eating and nutrition. Despite converging evidence that OrNe is correlated with measures of psychopathology and personality traits, there is relatively little empirical data relating OrNe and HeOr to eating and health-promoting behavior.METHODS:
Aim 1 exploratory structural equation modeling was used to evaluate the factor structure of an English-language version of the Teruel Orthorexia Scale, the only measure of OrNe that also assesses HeOr in two samples (Yoga practitioners, N = 469, and Mechanical Turk workers, N = 453). Aim 2 conducted in the Mechanical Turk sample, partial correlation and linear regression analyses were used to evaluate the relationships of OrNe and HeOr with other symptoms of, and clinical impairment from, disordered eating, food choices, diet quality, body mass index (BMI), nutrition knowledge, alcohol/tobacco/vaping use, and sedentary behavior.RESULTS:
The two-factor structure of the TOS was replicated. HeOr and OrNe had opposing relationships with measures of disordered eating behavior and distress, food choices, diet quality, and nutrition knowledge. HeOr was negatively related to BMI, whereas OrNe was positively related to substance use and sedentary behavior.CONCLUSIONS:
OrNe and HeOr are distinct latent constructs, with the latter reflecting non-pathological behavior. Only OrNe is related to elevated disordered eating and clinical impairment. Despite involving obsessions and compulsions related to healthy eating, OrNe was associated with relatively unhealthy eating and other lifestyle behaviors.
