Prevalence and factors associated with depression and anxiety in living liver donors: A systematic review and meta-analysis

Objective: This study aimed to systematically review the prevalence and factors associated with depression and anxiety in living liver donors after liver transplantation.Methods: Five English language electronic databases and four Chinese language electronic databases were searched from inception to February 2023. Two investigators independently extracted the data and assessed the study quality. The pooled prevalence was calculated using STATA software (version 14.0). We performed a narrative review to summarize the factors associated with depression and anxiety in living liver donors after liver transplantation. The protocol of this study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database, registration number: CRD42021290071. Results: This study included 39 articles involving 18,577 participants. The pooled prevalence was 6.3% [95% confidence interval (CI) (4.1-8.9%)] for depression in living liver donors, and 10.0% [95% CI (4.0-18.1%)] for anxiety. Prevalence of clinically significant depressive or anxiety symptoms was higher (15.7% and 17.4%) compared with disorders (2.7% and 2.2%). The prevalence of depression and anxiety was highest within 3 months post-donation. Specifically, female donors, serious postoperative complications, and recipients' poor health/death have been reported as factors having a negative influence on depression and anxiety.Conclusions: Collected evidence showed that the overall prevalence of depression or anxiety of living liver donors was high. Therefore, early detection and timely treatment of psychological disorders are crucial to promote positive psychiatric health outcomes and ensure the quality of life of living liver donors.
