The effect of maternal educational status, antenatal care and resumption of menses on postpartum contraceptive use in Ethiopia: systematic review and meta-analysis

Abstract

The postpartum period is a crucial starting point for the delivery of family planning services. To date, there are numerous primary studies in Ethiopia on postpartum contraceptive use and related factors. However, the results of key variables are inconsistent, making it difficult to use the results to advance the service dimensions of postpartum contraceptive use in the country. Therefore, this systematic review and meta-analysis was required to summarize this inconsistency and compile the best available evidence on the impact of maternal educational status, antenatal care and menstrual resumption on postpartum contraceptive use in Ethiopia. PubMed, Google Scholar, Scopus, Science Direct, and the repositories of online research institutes were searched. Data were extracted with Microsoft Excel and analyzed with the statistical software STATA (version 14). Data on the study area, design, population, sample size, and observed frequency were extracted using the Joanna Briggs Institute tool. To obtain the pooled effect size, a meta-analysis was performed using a weighted inverse variance random effects model. Cochran's Q X2 test, and I2 statistics were used to test for heterogeneity, estimate the total quantity, and measure the variability attributed to heterogeneity. A mixed-effects meta-regression analysis was performed to identify possible sources of heterogeneity. To examine publication bias, the Eggers regression test and the Beggs correlation test were used at a p-value threshold of 0.001. Of the 654 articles reviewed, 18 studies met the inclusion criteria and were included in this meta-analysis. Overall, the final analysis includes 11,263 study participants. In Ethiopia, postpartum contraceptive use correlated significantly with maternal educational status (OR = 3.121:95% CI 2.127–4.115), antenatal care follow-up (OR = 3.286; 95% CI 2.353–4.220), and return of the mother's menses (OR = 3.492; 95% CI 1.843–6.615). A uniform meta-regression was performed based on publication year (p = 0.821), sample size (p = 0.989), and city of residence (p = 0.104), which revealed that none of these factors are significant. The use of postpartum contraceptives was found to be better among mothers who are educated, attended antenatal appointments, and resumed their menstrual cycle. Based on our research, we strongly recommended that antenatal care use and maternal educational accessibility need to improve. For family planning professionals, removing barriers to menstruation resumption should be a key priority.
