Prevalence of suicidal ideation in pregnancy and the postpartum: A systematic review and meta-analysis
Abstract
BACKGROUND: Suicidal ideation, a significant risk factor of suicide, is considered a potential trigger for intervention prior to self-harm or suicide; however, the prevalence of maternal suicidal ideation varied widely between studies. This review aims to synthesis the available evidence to estimate the prevalence of maternal suicidal ideation before and after pregnancy.
METHODS: We searched six English databases (PubMed, Web of Science, Embase, the Cochrane Library, PsycINFO, CINAHL) and three Chinese databases (China National Knowledge Infrastructure, Wang Fang, Chinese Biomedical Literature Databases) from database inceptions before August 31, 2020; and checked the reference list for relevant studies. Data in the included studies were used to calculate the prevalence of maternal suicidal ideation. Subgroup analysis and meta-regression were performed to detect the potential sources of heterogeneity.
RESULTS: 6094 potentially studies were identified. 71 studies, including 23 cohort studies, 47 cross-sectional studies, and 1 RCT study, were included for final analysis. The total participants were 92146, with sample size ranged from 23 to 22118. The included studies were from 23 different countries distributing on six continents, most of the studies were conducted in Asia (n = 18), North America (n = 16), and South America (n = 15). The pooled prevalence of maternal suicidal ideation reported by eligible studies was 8% (95% CI 7-10%), with 10% in antenatal and 7% in…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 18 participants or records.
