The demographic profile of borderline personality disorder.

In a survey of borderline personality disorder, 23 studies that included data on age, sex, or race of the patient samples were identified. Comparison of patients who had borderline personality disorder with control groups in these studies revealed that a significant preponderance of patients with the disorder were young, white, and female. This finding cannot be considered conclusive because data were pooled from studies with questionable sampling techniques. Yet, this demographic profile warrants confirmation because it may imply diagnostic biases or actual differences in the prevalence of borderline personality disorder among various groups.
