Objective:To study the prevalence of body dysmorphic disorder (BDD) in patients with plastic and cosmetic by performing meta-analysis.Methods:We searched, collected and screened the published studies on the prevalence of BDD in population with cosmetic surgery at home and abroad, and conducted a meta-analysis to calculate the prevalence of BDD in this population. The literatures were screened strictly according to the inclusion and exclusion criteria, and the quality of the included studies was evaluated with reference to AHRQ scale. Cochrane Q test was used to analyze the heterogeneity among the studies. If there was no heterogeneity, the fixed effect model was used for the pooled analysis of effect size. If there was heterogeneity, the random effect model was used for the pooled analysis of effect size, and the potential sources of heterogeneity were tested by meta regression, and subgroup analysis was performed. Sensitivity analysis was performed to test the stability of the result. Funnel plot was used to determine whether publication bias existed.Results:Thirteen articles were finally included in the meta-analysis, including 4 Chinese articles and 9 English articles, with a total sample size of 3 366 cases. A total of 435 cases of BDD were detected. The AHRQ scores of the 13 articles were greater or equal to 4 points. Heterogeneity test showed that there was a high degree of heterogeneity among the 13 studies, so the random effect model was used for pooled analysis of effect size. The results showed that the prevalence rate of BDD in population with plastic surgery was 13% (95% CI 9% - 18%). Sensitivity analysis shows that the result calculated by the random effect model are stable and reliable. Meta regression analysis showed that the difference of surgical site was one of the reasons for heterogeneity. Thirteen articles were divided into two groups according to patients with rhinoplasty and plastic surgery in other parts, and meta-analysis was conducted respectively. There were 3 articles in rhinoplasty group and 10 articles in other part of the plastic surgery. The result showed that the prevalence of BDD was 29% (95% CI 24% - 35%) in rhinoplasty group and 9% (95% CI 8% -10%) group with plastic surgery in other parts. Funnel plot analysis showed that there was no publication bias in this study. Conclusions:About 9% of the people with cosmetic surgery suffer from BDD, and the prevalence of BDD in the people seeking nasal plastic surgery can be as high as 29%. Plastic surgeons should pay special attention to this kind of people in clinical work, and use appropriate screening tools to identify them, so as to provide more scientific diagnosis and treatment plan for patients. Aesthetic plastic surgeons should pay attention to the evaluation of patients’ psychological state in clinical work.
