Correlates of facility-based delivery among women of reproductive age from the Digo community residing in Kwale, Kenya

Objective This study sought to describe factors associated with facility-based delivery among women of reproductive age in Kwale County, Kenya. Results Between March and December 2015, 745 women from 15 villages were interviewed through a cross-sectional household survey. Respondents were selected using stratified, systematic sampling and completed a sexual and reproductive health questionnaire. Of 632 (85%) women who had a previous birth, 619 (98%) reported antenatal care attendance. Of these, 491 (79%) subsequently had a facility-based delivery. Factors associated with increased likelihood of facility delivery included respondent’s education (odds ratio, OR = 2.0, 95% confidence interval, CI 1.2–3.2, P = 0.004), ideal antenatal care attendance (OR = 2.3, 95% CI 1.4–3.7, P = 0.001) and pregnancy intention (OR = 1.5, 95% CI 1.0–2.2, P = 0.040). Being in a polygamous relationship (OR = 0.6, 95% CI 0.3–0.9, P = 0.024) and having a husband ≥ 40 years (OR = 0.5, 95% CI 0.3–0.9, P = 0.013) were associated with reduced likelihood of facility delivery. Respondent’s education (aOR = 1.9, 95% CI 1.1–3.3, P = 0.030) as well as ideal ANC attendance (aOR = 2.0, 95% CI 1.0–3.8, P = 0.040) remained significantly associated with facility delivery in multivariate analyses.

Introduction
While obstetric delivery in a health facility has been associated with favourable maternal and neonatal outcomes, rates of facility-based delivery in the developing world remain unexpectedly low [1,2]. This is attributed to various factors including the influence of sociocultural context, low perception of risks associated with pregnancy and childbirth, fear of discrimination during delivery as well as barriers associated with physical distance to a health facility and costs associated with delivery [3].
Two European Commission-funded projects seeking to improve uptake and utilization of maternal and child health (MCH) services, especially facility-based delivery and contraception, were implemented in Kwale county, Kenya. The Missed Opportunities in Maternal and Infant (MOMI) health project leveraged missed opportunities in the postpartum period using facility and communitybased interventions [4]. The Mama na Mtoto (MNM) II project aimed to create demand for MCH services by enhancing community structures and meaningfully involving target communities [5].
Previous findings from these studies have shown high levels of contraceptive utilization among women of reproductive age (WRA) in this setting. This was associated with educational attainment, parity, antenatal (ANC) attendance at last delivery as well as intention to delay or stop future births [6]. Additionally, it was found that lay community health volunteers were instrumental in building demand for MCH services by acting as a The present study sought to further build on these findings by describing factors associated with facility-based delivery. As previously noted, while high rates of ANC attendance have been reported in this setting, the proportion of those pregnancies that are ultimately delivered at home still remains high [8,9]. Findings from this study will inform priorities for better MCH programming and contribute to improved uptake and utilization of skilled assistance at birth.

Study design
Data for this study were collected through a cross-sectional household survey conducted in Kwale between March and December 2015. The methods have been comprehensively described previously [6]. Briefly, a structured sexual and reproductive health (SRH) household questionnaire (see Additional file 1) was administered to women between 18 and 45 years. A sample size of ~ 350 respondents was estimated based on an anticipated 50% frequency of facility-based deliveries in this setting, a sample design effect of 2.5, Z-statistic of 1.96 for a 95% confidence level in the estimation, 10% nonresponse rate, and a 2.5% margin of error. Stratified, systematic random sampling was used to select respondents. Every qualifying female respondent per household was included in the study unless they failed to provide written informed consent or were not resident in the village for more than 6 months.

Data management and statistical analyses
Data were entered into a Microsoft Access (Microsoft Inc. Seattle, WA, USA) spreadsheet and migrated to Stata version 12 (StataCorp Inc., College Station, TX, USA) for statistical analyses. Demographic characteristics were summarized as counts (N)/percentages (%) for categorical data and median (IQR) for continuous data and compared using Pearson's Chi squared test (categorical) and Wilcoxon rank-sum test (continuous). The outcome of interest was self-reported delivery at a health facility among women reporting a previous birth. Odds of facility-based delivery were calculated among women with each characteristic of interest versus the reference group using multivariate logistic regression models with adjusted Odds Ratios (ORs) and 95% confidence intervals (CIs) being reported. All statistical tests were evaluated using a 2-sided α-value of 0.05.

Ethical consideration
Ethical approval for the study was obtained from the Research Ethics Committee of the Aga Khan University, Nairobi (2014/REC-51) and the Ethics Review Committee of the University of Nairobi and Kenyatta National Hospital (P502/08/2014). A research permit from the National Commission for Science, Technology and Innovation (#4703) was also obtained to facilitate the conduct of research activities in the community. All participants provided written informed consent.
Six hundred and thirty-two (85%) respondents reported that they had ever given birth with the median (IQR) number of total births reported being 4 (2-5). Of these, 619 (98%) had attended ANC during their last pregnancy. The median (IQR) duration of pregnancy at the time of attending the first ANC visit was 5 (4-6) months while the median (IQR) number of ANC visits attended was 4 (3-5). Further, 75 (10%) women were currently pregnant at the time of the interview, with a median (IQR) pregnancy duration of 6 (4-7) months. Of these, 60 (81%) reported having ever attended ANC.
Among women who reported a previous birth, 493 (78%) had delivered in a health facility during their last pregnancy, 107 (17%) had delivered in their own home while 32 (5%) had delivered in someone else's home. This pattern was replicated among those who had attended ANC during their last pregnancy with 483 (78%), 99 (16%) and 31 (5%) women having delivered in a health facility, in their own home and in another person's home, respectively. Among 13 women who had not attended ANC during their last pregnancy, only 8 (60%) had delivered in a health facility (Fig. 1).

Discussion
This cross-sectional survey of WRA from the Digo community resident in Kwale County, Kenya revealed a high proportion of facility-based delivery at recent birth. Women were more likely to have delivered in a health facility if they had ever attended school and if they had intended to get pregnant. Women who reported receiving ideal ANC services during their previous pregnancy were also more likely to deliver in a facility. Conversely, women were less likely to deliver in a health facility if they were in a polygamous relationship and if their husband/partner was older.
Our findings are consistent with key characteristic of pregnancy and childbirth in the developing world where the proportion of facility-based deliveries lags behind high rates of ANC attendance [10][11][12]. This is despite the fact that facility-based delivery has been associated with favourable maternal and neonatal outcomes. Different studies have revealed various barriers associated with this disparity including traditional and familial influences, high costs, low perceived quality of care and fear of discrimination during facilitybased delivery [3, [13][14][15][16]. Women who have otherwise attended ANC well have reported fearing poor quality of services during childbirth which makes them prefer a home delivery [17][18][19]. Further, our findings show that the proportion of facility-based deliveries has increased over time, which is consistent with several other studies in this setting [20,21]. This is likely related to the government of Kenya's policy on free maternity services that was rolled out in June 2013. This policy has been credited with increasing the absolute numbers of pregnant women who deliver in health facilities [22]. However, our study showed a disparity between ANC attendance and facility-based delivery. The number of women who ultimately delivered in a health facility was lower than those who reported attending ANC in the same pregnancy.
The antenatal period offers a unique opportunity to promote healthy behaviors and practices. It serves as an ideal point during a woman's pregnancy for discussing the choice of place of delivery [23,24]. It also offers an opportunity to influence the decision-making process and respond to complaints and concerns [25,26]. Our findings show that the likelihood of a facility-based delivery in this setting was more than twice as likely if a woman had received ideal ANC services during her pregnancy. In order to improve maternal and neonatal outcomes therefore, it is important to leverage demand-side factors that harness missed opportunities during ANC so as to promote uptake of facility-based delivery.
Studies have shown that educated girls and women are able to make better-informed health-related decisions [27,28]. Successful completion of primary education among African girls has also been strongly associated with better SRH outcomes [29]. Our findings show that women who had ever attended school in this setting were twice as likely to have delivered in a health facility compared to those who had never attended school. Programs targeting to improve MCH outcomes should incorporate interventions encouraging educational attainment as well as promoting adult literacy training.
Finally, we have previously shown that pregnancy intention was associated with uptake of contraceptive services. The current findings reinforce the fact that women who plan if and when to get pregnant are more likely to deliver in a health facility. Previous studies have had mixed results regarding the role of pregnancy intendedness on influencing skilled attendance at birth especially after accounting for socioeconomic and demographic factors [30]. What is clear however, is that pregnancy intendedness could influence the quality of ANC services sought for. As our findings reveal, this could ultimately affect choice of place of delivery.

Limitations
These findings need to be interpreted within the context of several limitations: • Lack of data on some known correlates of facility delivery including household income as well as distance to health facility/time required to reach health facility. • Cross-sectional study design leading to inability to infer causality. • Self-reported responses may be subject to reporting bias.
