Achieving reductions in the unmet need for contraception with postpartum family planning counselling in Ethiopia, 2019–2020: a national longitudinal study

Background An unmet need for contraception is associated with unintended pregnancy and adverse maternal and childhood outcomes. Family planning counselling is linked with reduced unmet need for contraception. However, evidence is lacking in Ethiopia on the impact of integrated family planning counselling on the unmet need for contraception. This study aimed to examine the association between family planning counselling and the unmet need for contraception in Ethiopia. Methods We used community-based prospective cohort study data from a nationally representative survey conducted by Performance Monitoring for Action Ethiopia between 2019 and 2020. Women who had received three maternal and child health (MCH) services (n = 769) - antenatal care (ANC), facility delivery and child immunisation - were included in this study. The primary exposure variable was family planning counselling provided during the different MCH services. A weighted modified Poisson regression model was used to estimate the adjusted relative risk (aRR) of the unmet need for contraception. Results The prevalence of family planning counselling during ANC, prior to discharge, and child immunisation was 22%, 28%, and 28%, respectively. Approximately one-third (34%) of the women had an unmet need for contraception. Family planning counselling prior to discharge from the facility was associated with reductions in the unmet need for contraception (aRR 0.88; 95% CI 0.67, 1.16). The risk of unmet need for contraception was 31% (aRR 0.69; 95% CI 0.48, 0.98) less likely among women who had received family planning counselling during child immunisation services. However, family planning counselling during ANC was associated with an increased unmet need for contraception (aRR 1.24; 95% CI 0.93, 1.64). Conclusion Strongest evidence was observed for moderate associations between reductions in the unmet need for contraception and family planning counselling during the provision of child immunisation services in Ethiopia.
