Body dysmorphic disorder (BDD) is characterised by a preoccupation with a perceived defect in appearance. This preoccupation results in the completion of repetitive/time consuming behaviours to reduce distress. While the disorder results in considerable distress and impairment, the prevalence of the disorder is largely unknown, as BDD has not been examined in large epidemiological studies. The aim of the current study was to provide an estimate of BDD prevalence in a variety of settings using a meta-analytic approach using only studies that have made a diagnosis using a structured diagnostic interview. Twenty-two studies met criteria (n = 7159) and the pooled point-prevalence estimate for BDD was 11.3% across all studies with high levels of heterogeneity (I = 95.81). The pooled point-prevalence estimate was 20.0% in cosmetic/dermatology settings, 7.4% in mental health settings, and 6.7% in 'other' settings (including students and professional ballet dancers). The risk of bias assessment indicated questionable methodological quality in some of the included studies. While this study provides an important improvement on the existing literature there is a need to include BDD in epidemiological studies in order to have a more accurate understanding of the prevalence rate of this mental health condition in the community.
躯体变形障碍（BDD）的特征是对外观感知缺陷的过分关注。这种过分关注会导致重复/耗时的行为完成，以减轻痛苦。虽然该障碍会导致相当大的痛苦和损伤，但由于 BDD 尚未在大型流行病学研究中进行检查，因此该障碍的患病率在很大程度上是未知的。本研究的目的是使用仅使用结构化诊断访谈进行诊断的研究的荟萃分析方法，提供各种环境中 BDD 患病率的估计。有 22 项研究符合标准（n=7159），所有研究的 BDD 点患病率综合估计值为 11.3%，异质性水平很高（I=95.81%）。在美容/皮肤科环境中的综合点患病率估计值为 20.0%，在心理健康环境中为 7.4%，在“其他”环境（包括学生和专业芭蕾舞演员）中为 6.7%。偏倚风险评估表明，一些纳入的研究存在方法学质量问题。虽然这项研究对现有文献有了重要的改进，但仍需要在流行病学研究中纳入 BDD，以便更准确地了解该心理健康状况在社区中的患病率。
