Clinical characteristics of trichotillomania with trichophagia
Open accessAbstract
Objective Little is known about trichophagia in individuals with trichotillomania. Although studies have mentioned the behavior, no previous studies have examined clinical correlates of trichophagia.Method We examined the clinical correlates of trichophagia in 68 subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, trichotillomania (85.3% females; mean age, 35.0 +/- 12.5). Comorbidity data were obtained with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Trichotillomania severity was assessed with the Psychiatric Institute Trichotillomania Scale and the Massachusetts General Hospital Hairpulling Scale. Social/occupational functioning was examined using the Sheehan Disability Scale. All variables were compared in trichotillomania subjects with and without trichophagia.Results Of the 68 subjects with trichotillomania, 14 (20.6%; 95% confidence interval, 12.7%-31.6%) reported current trichophagia, and an additional 9 (13.2%) ate their hair or the root episodically. There were far more similarities than differences in trichotillomania subjects with current trichophagia and those without, although those with trichophagia were significantly more likely to be male (P = .013) and have more severe trichotillomania (according to the Massachusetts General Hospital Hairpulling Scale) (P = .010).Conclusions These preliminary results suggest that trichophagia is not uncommon in individuals with trichophagia. Subjects with and without trichophagia were similar in most domains that were examined.

Approximately 10%-20% of people with trichotillomania eat their hair after pulling it ("trichophagia"), which can result in gastrointestinal obstruction and the formation of intestinal hair-balls ("trichobezoars") which can require surgical intervention.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
