Utilization of optimal antenatal care, institutional delivery, and associated factors in Northwest Ethiopia.

Optimal antenatal care visits (ANC4+) and institutional delivery are essentials to save lives of the women and the baby during pregnancy and delivery. Though focused antenatal care visits and institutional delivery is recommended by World Health Organization, Ethiopia has sub-optimal antenatal care and lagged facility delivery. A community-based cross-sectional study was conducted among 811 lactating women in Northwest Ethiopia. Multivariable logistic regression analysis was performed using 95% confidence level and p < 0.05. The prevalence of optimal antenatal care visits and institutional delivery were 39.6% (95%CI: 36.2-43) and 62.6% (95%CI: 59.2-66), respectively. Maternal education (AOR = 2.05; 95%CI: 1.14, 3.69), home visiting by health extension workers (AOR = 1.57; 95%CI: 1.01, 2.29), and early antenatal care booking (AOR = 11.92; 95%CI: 8.22, 17.31) were significant predictors of optimal antenatal care. Exposure to mass media (AOR = 1.65; 95% CI: 1.02, 2.65); intended pregnancy(AOR = 1.68; 95%CI:1.12, 3.63); parity of one (AO = 3.46; 95% CI: 1.73, 6.89); 1-3 antenatal care visits (AOR = 2.17; 95% CI: 1.29, 3.63); and ANC4 + (AOR = 3.57; 95% CI: 2.07, 6.14); history of pregnancy-related complications(AOR = 1.63; 95%CI: 1.04, 2.57), and access to transportation to reach a health facility(AOR = 1.58; 95%CI: 1.00, 2.45) were significant predictors of institutional delivery. Addressing the modifiable factors identified in this study could improve optimal antenatal care visit and institutional delivery.
