The level and deriving factors of repeat-induced abortion in Ethiopia: A systematic review and meta-analysis.

Background: Despite repeat induced abortion is a growing challenge for both developing as well as developed countries, abortion-related complications are found to be higher among women in developing countries. This systematic review and meta-analysis was intended to assess the level of repeat-induced abortion and its deriving factors in Ethiopia.

Methods: Different data sources such as PubMed, EMBASE, Google Scholar, and University online data bases were used to identify candidate articles for this systematic review and meta-analysis. The article search was conducted from June 10 to 26, 2020. The Newcastle-Ottawa Quality Assessment Scale (NOS) was used to assess the quality of the included studies. Data extraction was performed through a format prepared on Microsoft excel work book and exported to Stata 11 for analysis. The heterogeneity of the studies was tested using Cochran (Q test) and I test statistics. Publication bias was assessed by funnel plot and Egger's regression asymmetry test. Subgroup-analysis was conducted based on sample size and study Regions.

Results: Five studies with 2000 participants who visited health facilities for abortion services were included in this systematic review and meta-analysis. The pooled level of repeat-induced abortion was found to be 29.93% (95%, CI 23.15%, 36.71%). Urban residence (OR = 5.10, 95%, CI 2.51, 10.33), illiteracy (OR = 4.12, 95%, CI 2.40, 7.07), having multiple sexual partners (OR = 6.28, 95% CI 4.28, 9.22), and early sexual initiation (OR = 3.80, 95%, CI1.76, 8.19) were found to be the deriving factors for experiencing repeat induced abortion. However, there was no significant association between ever use of family planning and repeat induced abortion (OR = 1.03, 95%, CI 0.09, 11.59).

Conclusion: The level of repeat-induced abortion was found to be high in Ethiopia. High risk of experiencing repeat-induced abortion was reported among participants who were urban residents, illiterate, who had multiple sexual partners, and early sexual initiation. However, a statistically significant association was not found between ever use of family planning and repeat-induced abortion. Health education shall be given about the risk of subsequent abortion and the relevance of avoiding unintended pregnancy, multiple sexual partners, and early sexual initiations through various mechanisms.
