Abstract

Background

Perinatal mortality remains a problem in Ethiopia. Findings of primary studies varied on level of perinatal mortality and its predictors including inter-pregnancy interval. The aim of this review was to estimate the pooled perinatal mortality rate, its trend overtime and verify the association with inter-pregnancy interval in Ethiopian context.

Methods

Studies were accessed through the electronic web-based search strategies from PubMed, ScienceDirect, Hinari for health via Research4Life, Google and Advanced Google search, and retrieving via relevant references using a combination of medical subject headings (MeSH terms) and key words related with inter-pregnancy interval. R version 3.4.3 software was used for the meta-analysis. A forest plot and I2 test were done to assess heterogeneity. Sensitivity analysis and subgroup analysis were done to deal with heterogeneity. A weighted inverse variance random-effects model was applied to estimate pooled effect sizes. A funnel plot and Egger’s regression test were done to check publication bias.

Results

A total of 34 studies used to answer review questions (30 for perinatal mortality rate and its trend estimation from 1997 to 2019 and 8 for its relationship with inter-pregnancy interval). The pooled perinatal mortality rate was 51.3 per 1000 total births (95% CI: 40.8–62.8). The pooled stillbirth rate was 36.9 per 1000 births (95% CI: 27.3–47.8) and early neonatal mortality rate was 29.5 per 1000 live births (95% CI: 23.9–35.6). Increasing trend was seen in stillbirth rate (23.7 to 36.9 per 1000 births) while decreasing trend in early neonatal mortality rate (51 to 29.5 per 1000 live births). Slight reduction trend was observed in overall perinatal mortality rate (66 to 51.3 per 1000 births). An inter-pregnancy interval less than 15 months was found to be statistically significantly associated with perinatal mortality; pooled OR = 2.76 (95% CI: 2.1–3.62). Spacing pregnancy for at least 15 months was related with reducing perinatal mortality by 64% (95% CI: 52.38, 72.38%).

Conclusions

In Ethiopia, perinatal mortality rate remains high. Insignificant reduction trend was observed in overall perinatal mortality rate. Counseling couples about the importance of spacing pregnancy and intensifying long-acting contraceptive use will help in reducing perinatal mortality related to poor pregnancy spacing.
