Increased history of childhood and lifetime traumatic events among adults with alopecia areata

BackgroundWhether adult alopecia areata (AA) is associated with childhood or total lifetime traumatic events is not known. Previous studies have investigated only the relationship with recent stressful events.ObjectiveWe sought to determine whether patients with AA experience more childhood or total lifetime traumatic events, as measured by the Traumatic Experiences Checklist.MethodsUsing a case-control study, data on 90 patients with AA and 91 control subjects were analyzed.ResultsSignificantly more patients with AA experienced total lifetime and early childhood traumatic events, with an odds ratio of 2.46 (95% confidence interval 1.15-5.28; P = .017) and 2.16 (1.15-4.06; P = .016), respectively. In patients with AA, the global impact score related to their traumatic experiences was significantly higher than in control subjects (P < .001). In addition, patients with AA experienced significantly more emotionally and physically traumatic events.LimitationThis case-control study is susceptible to recall bias and to confounding factors associated with stress caused by AA outbreaks or by a traumatic childhood history.ConclusionOur study documents an increased history of childhood trauma in patients with AA compared with control subjects.
