Depression outcome in women with recurrent spontaneous abortion: A systematic review and meta-analysis.

BACKGROUND

It is widely recognized that depression is highly prevalent among women experiencing recurrent spontaneous abortion (RSA), exerting detrimental effects on both the individual and the family.

OBJECTIVE

To assess the depression risk and associated factors among women with RSA.

DATA SOURCES

Our search strategy encompassed PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure (CNKI), and WANFANG. The research was conducted in May 2022. We included both randomized and nonrandomized studies that reported the prevalence of depression among women with RSA.

DATA EXTRACTION AND SYNTHESIS

Two independent evaluators reviewed the titles and abstracts, assessed the full-text papers, extracted data from the included studies, and evaluated their quality using the Newcastle-Ottawa Scale (NOS). We performed random-effects meta-analyses to pool the data. Odds ratios (ORs) and standardized mean differences (SMDs) were combined based on effect sizes for binary and continuous outcomes.

MAIN OUTCOMES

To conduct a meta-analysis to understand the risk of depression in women with RSA who were not treated with psychiatric medications, as well as an analysis of potential factors for depressive symptoms.

RESULTS

Out of the initially identified 527 papers, a total of 20 studies (N = 13087) that fulfilled the inclusion criteria were selected. Compared to healthy controls, patients with RSA had a significantly higher risk of depression (OR: 4.26, 95 % confidence interval [CI]: 2.44-7.41; SMD: 0.89, 95 % CI: 0.51-1.26). The occurrence of depression among RSA patients was found to be significantly associated with several factors including the severity of depressive symptoms (OR: 3.82, 95 % CI: 2.22-6.59), number of spontaneous miscarriages (SMD: 0.59, 95 % CI: 0.01-1.18), history of therapeutic termination of pregnancy (SMD: 0.20, 95 % CI: 0.09-0.32), history of live birth (SMD: -0.32, 95 % CI: -0.49--0.15), and duration of marriage (SMD: 0.15, 95 % CI: 0.02-0.27).

CONCLUSIONS

In clinical practice, it is crucial to provide appropriate psychological interventions for women undergoing RSA. These individuals face a significantly heightened risk of depression, which exhibits strong correlations with various demographic factors such as the severity of depressive symptoms, history of both spontaneous miscarriages and therapeutic termination of pregnancy, number of live births, and duration of marriage. Consequently, women who are suffering RSA deserves more assistance and emotional support.
