Prevalence of Prolonged Grief Disorder Adult Bereavement in East Asia: A Systematic Review and Meta-Analysis


Death is an inevitable and natural part of life, however, the emotional state of grief and pain after the passing of a family is devastating. While many recover over time, a minority experiences clinical dysfunction following a loss. Prolonged grief disorder (PGD) is a newly added diagnostic criterion in the DSM-5-TR to classify those who display pathological symptoms of grief for a prolonged period. The suggested pooled transcontinental prevalence rate of PGD is 9.8%. Eastern countries are suggested to have a lower prevalence rate compared to Western countries. This review aims to estimate the prevalence rate of PGD in the adult bereaved population of East Asia. A systematic literature search was conducted in PubMed, PsycINFO, and Web of Knowledge. Five eligible studies from China and Japan with 4004 bereaved individuals were identified. Meta-analysis revealed a pooled PGD prevalence of 8.90% (95% CI 0.2 - 17.6). The first systematic review and meta-analysis of the prevalence of PGD within the East Asian population suggests that nine out of one hundred bereaved adults in East Asia are at risk for PGD. Cultural differences in the East Asian bereaved cultural values and practices surrounding deaths might be responsible for the different prevalence. The few eligible studies only from two countries call for further investigation on PGD within the general bereaved population in other East Asian countries. However, the result should be interpreted cautiously due to the high degree of methodological heterogeneity as well as the lack of generalizability to other East Asian countries.
