Trichotillomania Prevalence in an Arab Middle Eastern Population.

Abstract

Trichotillomania (TTM) (hair-pulling disorder) is a relatively rare psychiatric condition. We are aware of no studies of this disorder in Arab Middle Eastern populations. We examine the prevalence and correlates of TTM in a community sample of individuals living in a large port city in western Saudi Arabia. An observational cross-sectional study of 511 adults aged 18 years or over living in Jeddah, Saudi Arabia, was conducted. After inquiring about demographic information and self-reported psychiatric disorders, the Massachusetts General Hospital Hair-Pulling Scale (MGH-HPS) was administered to assess symptoms of TMM. A total of 9 of 511 participants (1.8%) scored above the cutoff for suspected TTM on the MGH-HPS, whereas 203 (39.7%) had a history of hair-pulling. Those with suspected TTM were more likely to be female (2.8% vs 0.4% in males, P = 0.047) and somewhat more likely to have a history of obsessive-compulsive disorder (OCD) (6.7% vs 1.5%, P = 0.093). Hair pulling was also more common in unmarried, not living with family, and unemployed. Among those with a history of hair-pulling, the most frequent locations were from the face (62.7%), head (55.7%), and legs (15.3%). While a history of hair-pulling is common in this community sample (40%), suspected TTM is much less prevalent (<2%), although not rare by any means. When present, the condition is more common in women and possibly in those with OCD.
