Interrelationships Between Maternal Health Services in Uganda: A Structural Equation Analysis

Abstract Background Maternal health care and treatment services have a bearing on maternal mortality. Direct and Indirect factors affecting Maternal health outcomes therefore require understanding to enable well targeted interventions. This study, therefore, assessed the interrelationships between early antenatal care, health facility delivery and early postnatal care.Methods We investigated Maternal Health services using utilizing Antenatal care (ANC) within three months of pregnancy, Health facility delivery and utilizing postnatal care (PNC) within 48 hours after childbirth. The 2016 Uganda Demographic and Health Survey data was used. During analysis, a Generalized Structural Equation Model using logistic link and binomial family option was used. The interrelated (Endogenous) outcomes were timely ANC, health facility delivery and timely PNC.Results Timely ANC (aOR=1.04; 95% CI=0.95-1.14) and(aOR=1.1; 95% CI=1.00-1.26) was directly related to increased odds of health facility delivery and timely PNC respectively. Factors that increased the odds of timely ANC as a mediating factor for health facility delivery and timely PNC were women age 35-39 (aOR=1.18; 95% CI=0.99-1.24) compared to women age 15-19, completing primary seven (aOR=1.68; 95% CI=1.58-1.81) compared to some primary, available health workers (aOR=1.06; 95% CI=0.97-1.18), complications (aOR=2.04; 95% CI=1.89-2.26) and desire for pregnancy(aOR=1.15; 95% CI=1.03-1.36). Factors that reduced the odds of timely ANC were being married (aOR=0.93; 95% CI=0.89-1.20), distance and cost of service being problematic (aOR=0.97; 95% CI=0.85-1.1) (aOR=0.5; 95% CI=0.37-0.82) respectively. Factors that significantly influenced health facility delivery through timely ANC were; unmarried (OR=1.03; (=1.04*0.99)), distance being problematic ((aOR=1.0; (=1.04*0.97)) and complications (aOR=2.02; (=1.04*1.94)). Factors that significantly influenced timely PNC through timely ANC were; women age 35-39 (aOR=1.3; (=1.18*1.1)) compared to 15-19, completing primary seven (aOR=1.68; (=1.68*1.1))compared to some primary and service cost being problematic (aOR=0.55; (=0.5*1.1)). Surprisingly, health facility delivery was not statistically significant as a mediator for timely PNC.Conclusion Attending antenatal care within first trimester was a mediating factor for health facility delivery and early postnatal care. Interventions in maternal health should focus on factors that increase antenatal care first trimester attendance in resource limited settings. Furthermore, Government should reduce on costs of attaining all maternal health services and emphasize girl education completion.
