Clinical presentation of body-focused repetitive behaviors in minority ethnic groups

Abstract

Background: Body-focused repetitive behaviors (BFRBs), such as trichotillomania and skin picking disorder, are psychiatric disorders characterized by repetitive grooming that result in hair loss or excoriations. Questions remain as to whether there are racial/ethnic differences in the clinical presentation of BFRBs. Methods: We recruited 539 adults with DSM-5 trichotillomania or skin picking disorder. Of these, 76 (14.1%) self-identified as Black, Asian, or Minority Ethnic (BAME), while 463 (85.9%) self-identified as white Caucasian (hereafter referred to as non-BAME). BAME and non-BAME participants were compared on demographics, symptom severity, comorbid conditions and psychosocial impairment. Results: Groups did not differ in terms of age, sex, or education levels. BAME individuals reported significantly more time spent picking or hair pulling per day compared to non-BAME individuals, and were less likely to have received treatment for their BFRB symptoms. Some differences were also found with respect to where on the body people pull and pick from. Discussion: In general, the clinical profiles of BFRBs appeared similar between those from BAME versus non-BAME backgrounds. However, differences were found in terms of treatments received and an aspect of symptom severity. The findings highlight the need to better understand the heterogeneity of BFRBs including potential health inequalities.
