Abstract:
Tanning in body dysmorphic disorder (BDD) has not previously been studied. In this study, 200 subjects with BDD were evaluated with measures to examine the prevalence of BDD-related tanning--i.e., darkening one's skin color by direct exposure to sunlight or artificial light which is motivated by a desire to improve a perceived appearance defect (i.e., a BDD concern). We also examined clinical characteristics of individuals who engaged in BDD-related tanning. 25% (95% CI, 19.0%-31.0%) of subjects reported BDD-related tanning. Among tanners, the skin was the most common body area of concern (84.0%). All tanners experienced functional impairment due to BDD, 26% had attempted suicide, and quality of life was markedly poor. 52% of tanners had received dermatologic treatment, which was usually ineffective for BDD symptoms. Tanners were more likely than non-tanners to compulsively pick their skin. In conclusion, tanning--a behavior with well-known health risks--is a relatively frequent BDD-related behavior.
