Background: Delivery at health institutions under the care of trained health-care providers and utilization of postnatal cares services plays vital roles in promoting child survival and reducing the risk of maternal mortality. More than 80 % of maternal deaths can be prevented if pregnant women access to essential maternity cares like antenatal care, institutional delivery and postnatal care services. Thus, this study aimed to assess institutional delivery and postnatal care services utilizations in Abuna Gindeberet District, West Shewa, Oromiya Regional State, Ethiopia. Methods: A community-based cross-sectional study design was employed among 703 randomly identified mothers of Abuna Gindeberet district in March, 2013. Data were collected through interviewer-administered questionnaires and analyzed using SPSS version 16.0. Descriptive, bivariate and multivariate analyses were used to determine prevalence and to identify associated factors with institutional delivery and postnatal care, considering p-value of less than 0.05 as significant. The results were presented in a narrative forms, tables and graphs. Results: One hundred one (14.4 %) of mothers gave birth to their last baby in health institutions. From 556 (79.1 %) of respondents who heard about postnatal care services, only 223 (31.7 %) of them utilized postnatal care services for their recent childbirth. From the total postnatal care users, 204 (91.5 %) of them took the services from health extension workers. Decision-making styles, household distances from health institutions, household being model family and ANC services utilizations were found to be statistically significant with both institutional delivery and postnatal care services utilizations. But educational status of husbands was statistically significant with only postnatal care services utilizations. Conclusions: Both institutional delivery and postnatal care services utilizations from health institutions were low. Decision-making styles, household distances from health institutions, household being model family and ANC services utilizations were the common factors that affect institutional delivery and postnatal care services utilizations from health institutions. Therefore, giving attention to the identified factors could improve and sustain institutional delivery and postnatal care services utilizations from health institutions.
A community-based cross-sectional study was conducted among 703 women who gave birth in the last 12 months in Abuna Gindeberet district, West Shewa Zone, Oromiya Regional State in March 2013. The district had 42 rural sub-districts from which 14 of them randomly selected. The rationale behind selecting 14 sub-districts over 42 is to include representative sample which mean in some literature of world health organization (WHO), the sample must be between 30 and 50 % of total population. Therefore, we tried to include one-third of the total population [7]. In each selected sub-districts, households with under 1-year children identified through census and sampling frame was developed. Finally, study subjects were addressed through simple random sampling by using sampling frame developed from conducted census data [8]. The sample was determined using single population proportion formula with an assumption of level of confidence of the study 95 %, sampling error tolerated 5 % and proportion of institutional delivery care services utilization (P) 50 % used. Design effect of 1.7 and a non-response rate of 10 % were also considered. Design effect 1.5 to 2 is enough in cross sectional study which done in multistage sampling. Depending on the population under study whether the community is homogeneous or heterogeneous we can use starting from 1.5 to 2 design effect. If we consider the community is heterogeneous, we can use design effect 2. Again, if we consider the community is homogeneous, we can use design effect 1.5 [9, 10]. According to this, in this study the rural dispersed population is our study. Even though, they are dispersed population, all of them are rural. Two things considered in this condition, being all of them rural makes them homogeneous population and being dispersed population makes them heterogeneous population. Therefore, since these two conditions were present, we used design effect averagely or in middle of the range (because we can use starting from 1.5 up to 2 depending on condition of the population). Postnatal care: the services given to a mother for a period of 6 weeks from the time of delivery in their previous delivery from health institutions. Decision making style: It is the ways of determining and control over resources when women should seek health care services. The style may be both husband and wife decides together or separately by individual. Model family: is a family that applied all health extension packages at their home and got certificates of appreciations from health extension workers. Structured questionnaires, which address the objectives of the study, were adapted from pertinent literatures [11–13, 15–17, 18–20]. The questionnaires translated into the local language – Afan Oromo and retranslated to English. Pre-test was done on 5 % of the sample size in sub districts (kebeles) different from those selected sub-districts for the study before actual data collections. House to house, data collection was made through interviewer-administered questionnaires. Data entered into Epidata version 3.1 and exported to SPSS version 16.0 for analysis. Descriptive analysis was done to determine the prevalence of institutional delivery care services and postnatal care services utilizations. Binary and multiple logistic regression analyses by backward conditional method were used to identify associated factors with institutional delivery care services and postnatal care services utilizations. Variables that had p-value of less than 0.05 by binary logistic regression were included in the multiple logistic regression analysis. A p-value of 0.05 was used as cutoff point to identify statistically significant variables.
