The Prevalence of Body Dysmorphic Disorder in Outpatient Dermatology Clinics: A Systematic Review

Abstract

Body Dysmorphic Disorder (BDD) is a psychiatric condition involving a preoccupation with physical appearance disproportionate to physical findings, which are often absent altogether. Previously published data has estimated its prevalence at 11.3-11.9% approximately, across various medical specialties. No recent systematic reviews strictly related to dermatology clinics and the prevalence of BDD have been published. The goal of the review was to gather a pooled prevalence of BDD in outpatient dermatology clinics around the world and further underline the importance of its recognition and appropriate treatment. Twenty-one articles tackling BDD in outpatient cosmetic and general dermatology clinics were selected. Studies were graded based on the Newcastle-Ottawa Scale (NOS) and the Statistical Package for the Social Sciences software (SPSS) was used to a calculate a mean for the pooled prevalence, yielding a weighted mean prevalence of 12.5% among general dermatology patients and 25.01% among cosmetic dermatology patients. The mean prevalence of BDD among general dermatology patients fell within previously reported numbers. It was, however, markedly higher than previously reported in cosmetic dermatology patients, which we postulate could be due to dermatologists being at the forefront of non-invasive cosmetic procedures. As such, we conclude that given the high prevalence of BDD among dermatology patients, we highlight the importance of keeping a high index of suspicion of BDD among dermatologists, ways to uncover it in a clinical setting, and additional data showcasing the importance of psychiatric treatment of these patients for better outcomes, all while avoiding unnecessary interventions.
