BackgroundThe continuum of maternity care is a continuity of care that a woman receives during pregnancy, childbirth, and the postpartum period from skilled providers in a comprehensive and integrated manner. Despite existing evidence regarding maternal healthcare services discretely, the continuum of maternity care and its associated factors are not well-known in Ethiopia.ObjectiveThis study assessed the completion of the maternity continuum of care and associated factors among women who gave birth 6 months prior to the study in the Chelia district.MethodsA community-based cross-sectional study with a stratified random sampling technique was conducted among 428 mothers at 10 randomly selected kebeles. Pretested and structured questionnaires were used to collect data. Bi-variable and multivariable logistic regression analyzes were performed to identify associated factors. Adjusted odds ratio with its 95% confidence interval was used to determine the degree of association, and statistical significance was declared at a p-value of <0.05.ResultsIn this study, 92 (21.5%) mothers completed the continuum of maternity care. Secondary and above education of mothers (AOR = 4.20, 95% CI:1.26–13.97), ≤30 min spent on walking by foot (AOR = 4.00, 95% CI: 1.67–9.58), using an ambulance to reach health facility (AOR = 3.68, 95% CI: 1.23–11.06), para ≥5 mothers (AOR = 0.21, 95% CI: 0.05–0.90), planned pregnancy (AOR = 3.29, 95% CI: 1.02–10.57), attending pregnant women's conference (AOR = 13.96, 95% CI: 6.22–31.30), early antenatal care booking (AOR = 3.30, 95% CI: 1.54–7.05), accompanied by partners (AOR = 3.64, 95% CI: 1.76–7.53), and informed to return for postnatal care (AOR = 3.57, 95% CI: 1.47–8.70) were the factors identified.ConclusionIn this study, completion of the maternity continuum of care was low. Therefore, appropriate strategic interventions that retain women in the continuum of maternity care by targeting those factors were recommended to increase the uptake of the continuum of maternity care.
