The prevalence of prolonged grief disorder (PGD) and its symptoms among the bereaved population in China vary considerably.
This meta-analysis aims to estimate the prevalence of PGD and its symptoms among bereaved individuals in China.
We conducted a literature search in major Chinese and English databases from their inception to 4 October 2023, for cross-sectional studies on the prevalence of PGD or its symptoms in bereaved Chinese individuals. The risk of bias of the included studies and certainty of the evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data ('JBI checklist') and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE), respectively. The 'metaprop' package in R V.4.1.2 was used to synthesise the prevalence.
A total of 28 studies involving 10 994 bereaved individuals were included in the analysis, with JBI checklist scores between 3 and 7. The combined prevalence (95% confidence interval) of PGD and its symptoms was 8.9% (4.2% to 17.6%) and 32.4% (18.2% to 50.8%), respectively. PGD and its symptoms were most prevalent among those who had lost their only child (22.7%) and those bereaved by earthquakes (80.4%), respectively. The GRADE system assigned a very low certainty level to the evidence for the pooled prevalence of PGD and its symptoms.
The pooled prevalence of PGD and its symptoms indicate a potential high need for grief counselling services among bereaved individuals in China. This need is particularly pronounced in those who have lost their only child and those bereaved due to earthquakes. Further methodologically rigorous studies are needed to provide more accurate prevalence estimates.

在中国，居丧人群中持续性悲伤障碍（PGD）及其症状的患病率差异很大。
本荟萃分析旨在估计中国居丧个体中PGD及其症状的患病率。
我们在主要的中文和英文数据库中进行了文献检索，检索时间跨度从数据库建立至2023年10月4日，以查找关于中国居丧个体中PGD或其症状患病率的横断面研究。分别使用乔安娜·布里格斯研究所（Joanna Briggs Institute）关于报告患病率数据研究的批判性评价清单（“JBI清单”）和推荐分级、评估、制定与评价（GRADE）来评估纳入研究的偏倚风险和证据的确定性。使用R V.4.1.2中的“metaprop”软件包来综合患病率。
共有28项涉及10994名居丧个体的研究纳入分析，JBI清单评分在3至7分之间。PGD及其症状的合并患病率（95%置信区间）分别为8.9%（4.2%至17.6%）和32.4%（18.2%至50.8%）。PGD及其症状在失去独子的人群（22.7%）和因地震而居丧的人群（80.4%）中最为普遍。GRADE系统将PGD及其症状合并患病率的证据确定性评为极低。
PGD及其症状的合并患病率表明中国居丧个体对悲伤辅导服务有潜在的高需求。这种需求在失去独子的人群和因地震而居丧的人群中尤为明显。需要进一步开展方法学严谨的研究以提供更准确的患病率估计。
