Is prevalence of orthorexia nervosa less than 1 % : data from a US sample?
As in other countries, a large proportion of a non-clinical US sample scored in the orthorexia range on the ORTO-15. However, this instrument is likely unable to distinguish between healthy eating and pathologically healthful eating. Our estimate is that orthorexia nervosa like anorexia nervosa and bulimia nervosa, is not a common condition.
We found no increase in the prevalence of hand enthesophytes among persons with central knee BML on their knee MRI scans. This provides evidence against a systemic enthesopathic disorder in association with knee OA.
