Exploring the Prevalence and Etiological Factors of Body Dysmorphic Disorder in Cosmetic Surgery Populations: Implications for Enhanced Clinical Assessment.

[BACKGROUND] The prevalence of body dysmorphic disorder (BDD) varies across different clinical settings, with evidence indicating its notable presence not only in psychiatric environments but also in dermatology and plastic surgery. This article aims to investigate the etiological factors associated with the elevated incidence of BDD in plastic surgery outpatient settings, with the ultimate objective of enhancing the assessment process for potential cosmetic procedure candidates.

[METHODS] We recruited 531 patients seeking consultations or surgeries at the Department of Plastic Surgery, Peking University Shenzhen Hospital, from October 2022 to February 2024. The Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder (BDD-YBOCS) was utilized to diagnose BDD, and the Hospital Anxiety and Depression Scale (HADS) assessed psychological comorbidities. Statistical analyses included Spearman's correlation, Kruskal-Wallis, and chi-square tests.

[RESULTS] BDD was diagnosed in 11.3% of the participants, with significant variations related to gender (p = 0.042) and marital status (p = 0.026). A significant correlation was also displayed between BDD-YBOCS and HADS (Spearman's rho = 0.266, p < 0.001). Notably, BDD prevalence was higher during the COVID-19 pandemic (13.6%) compared to post-pandemic period (3.4%) (p = 0.003).

[CONCLUSION] This study elucidates the significant prevalence of body dysmorphic disorder (BDD) among patients seeking cosmetic surgery, highlighting critical demographic, psychological and environmental factors that contribute to its manifestation. Given the significant prevalence and the multifactorial nature of BDD, it is important to develop comprehensive assessment tools before cosmetic consultation that prioritize mental health alongside aesthetic considerations in the future.
