Predictors of postpartum family planning in Rwanda: the influence of male involvement and healthcare experience

Abstract

Background

Strengthened efforts in postpartum family planning (PPFP) is a key priority to accelerate progress in reproductive, maternal, newborn, and child health outcomes. This secondary data analysis explores factors associated with PPFP uptake in Rwanda. The purpose of this study was to explore variables that may influence PPFP use for postpartum women in Rwanda including health facility type, respectful maternity care, locus of control, and mental health status.

Methods

This secondary analysis of data from a cluster randomized control trial used information abstracted from questionnaires administered to women (≥ 15 years of age) at two time points—one during pregnancy (baseline) and one after delivery of the baby (follow-up). The dependent variable, PPFP uptake, was evaluated against the independent variables: respectful care, locus of control, and mental health status. These data were abstracted from linked questionnaires completed from January 2017 to February 2019. The sample size provided 97% power to detect a change at a 95% significance level with a sample size of 640 at a 15% effect size. Chi-square testing was applied for the bivariate analyses. A logistic regression model using the generalized linear model function was performed; odds ratio and adjusted (by age group and education group) odds ratio with 95% confidence interval were reported.

Results

Of the 646 respondents, although 92% reported not wanting another pregnancy within the next year, 72% used PPFP. Antenatal care wait time (p =  < 0.01; Adj OR (Adj 95% CI) 21–40 min: 2.35 (1.46,3.79); 41–60 min: 1.50 (0.84,2.69); 61–450 min: 5.42 (2.86,10.75) and reporting joint healthcare decision-making between the woman and her partner (male) (p = 0.04; Adj OR (Adj 95% CI) husband/partner: 0.59 (0.35,0.97); mother and partner jointly: 1.06 (0.66,1.72) were associated with PPFP uptake.

Conclusions

These results illustrate that partner (male) involvement and improved quality of maternal health services may improve PPFP utilization in Rwanda.

Background

Worldwide, there is significant unmet need for family planning in the postpartum period. Postpartum family planning (PPFP) is defined as the prevention of unintended and closely spaced pregnancies for the first 12 months following childbirth [1]. The average desired family size varies, but regardless, women typically spend about thirty years (three-quarters of their reproductive lives) trying to prevent pregnancy [2]. Distinctly from nulliparous women, parous women prioritize the ability to manage inter-pregnancy intervals and halt childbearing when desired in addition to avoiding unintended pregnancies [3, 4]. Thus, distinctive interventions for this population, compared to women who have not been pregnant, are necessary. More than 90% of women globally report a desire to space or limit additional pregnancies postpartum, however, 61% do not use contraception [5].

PPFP is one of the most effective methods to improve reproductive, maternal, newborn, and child health (RMNCH) outcomes and prevent unintended or closely spaced pregnancies following childbirth [3, 6,7,8]. The World Health Organization (WHO) distinguishes the postpartum period as the most imperative, yet overlooked stage in the lives of mothers and babies and advises at least 24 months between a birth and the subsequent pregnancy [8, 9].

Countries with high rates of facility-based deliveries provide an opportunity to address the unmet need for PPFP by offering contraceptive counseling prior to discharge [8]. One such country where PPFP has potential for great impact is the Republic of Rwanda. While the nation has dramatically reduced its maternal and newborn mortality rates and increased the use of modern contraception [10,11,12], 26% of Rwandan women have unmet family planning needs in their first year postpartum [13] and near one-half of births are conceived before the recommended interval of 24 months [14]. Contraception uptake postpartum in Rwanda has potential to prevent one in three maternal deaths [11]. Thus, accelerating national progress in RMNCH includes strengthened efforts in the area of PPFP [12].

Numerous infrastructure and health workforce developments have provided a foundation to facilitate PPFP uptake in Rwanda including: (1) public education campaigns [11, 15]; (2) health workforce reinforcements of skilled birth attendants and community health workers (CHWs) [11, 12, 15,16,17]; and (3) strengthened population-healthcare links through the mHealth system and an updated postnatal care (PNC) framework (Additional file 1: Fig. S1 [18,19,20,21,22]). This PNC framework, distributed in 2016, provides infrastructure for PPFP counseling [23,24,25,26,27]. Currently, prior to discharge at PNC 1, nearly a quarter of women enroll in a family planning method and two-thirds plan to engage in PPFP at a subsequent visit [8].

Multiple factors play a role in PPFP decision-making which must be further understood to deconstruct the facilitators and barriers to PPFP use. Health facility type, respectful maternity care, locus of control, and mental health status are potential elements that influence PPFP uptake. First, faith-based health facilities compose 30% of Rwanda’s healthcare system and supply critical gaps in care [28, 29]. Some denominations of faith-based facilities offer natural methods only (rhythm beads); “more effective” family planning options remain absent at these facilities leading to possible gaps in PPFP [30, 31]. Second, various attributes of respectful service delivery are central to patients’ notions of quality [32,33,34] and influences PPFP uptake, but limited data exist on this correlation [35]. Third, the locus of control denotes the extent to which an individual perceives authority over events in their lives [36]. An individual with an internal locus of control is empowered, they perceive authority over their life experiences; an external locus of control results in fault of outside forces for life events, the individual perceives powerlessness [36]. Research in East Africa and Rwanda illustrates the association between locus of control and utilization of PNC [18, 37,38,39] and thus increased likelihood of PPFP utilization [36]. Lastly, poor maternal mental health has been associated with preterm and low birth weight [40], substandard breastfeeding and immunization coverage [41], being underweight or stunted [42], increased rates of diarrhea and febrile disease [41, 43], and negative effects on child development [41]. Mental health status, except in the circumstance of psychiatric episodes [44], and engagement in PPFP practices, have not yet been explored. This work provides insights into how these factors may play a role in PPFP decision-making and uptake.

Methods

Study design and participants

This sub-analysis was conducted within the Preterm Birth Initiative (PTBi) Rwanda study [45], a collaboration among University of California San Francisco (UCSF), University of Rwanda, the Rwanda Ministry of Health (MOH), and the Rwanda Biomedical Center. As part of a cluster randomized control trial that tested a group model of antenatal (ANC) and PNC service delivery (NCT03154177), questionnaires were administered in person by study-trained data collectors to a cohort of women at two time points—one during pregnancy (baseline) and one after delivery of the baby (follow-up). The parent study included 36 health centers across five districts in rural and urban settings. Inclusion in the primary analysis of the parent study stated that participants must: (1) Be a minimum age of 15 years at the time of enrollment, (2) Attend the first ANC visit before 24 completed weeks of pregnancy, (3) Attend more than one ANC visit at one of the 36 study facilities, and 4) Consent to participate in the study and follow-up. Additional methods specific to the parent study are reported in the parent study protocol publication [46]. The dependent variable, PPFP uptake, was evaluated against the independent variables: respectful care, locus of control, and mental health status.

Sampling: parent study and sub-analysis

The baseline questionnaire was answered by a sub-set of parent study participants across trial arms made up of a convenience sample of the first five women to present for ANC per month. Similarly, the follow-up questionnaire was administered to a convenience sample of those who presented at the health center with newborns approximately six weeks after birth. Participants who completed both the baseline and follow-up questionnaire data, linked by a study key and were completed from January 2017 to February 2019, were included in this sub-analysis. The parent study obtained approval with both UCSF and University of Rwanda National Ethics Council institutional review boards. Participants completed written informed consent forms or selected to have it read aloud. This study protocol was reviewed and approved by the Rwanda National Ethics Committee (No 0034/RNEC/2017) and the UCSF Institutional Review Board (No 16-21177).

Data abstraction and analysis

Variables were defined by collated questions collaboratively selected by PTBi. The study variables are: respectful service, locus of control, and mental health status. The survey questions selected for this secondary analysis, respective predictors and outcomes, considerations to determine appropriate scoring of questionnaires, and methods to determine outcomes are detailed in Additional file 2: Table S1. Cronbach’s alpha scores (scale reliability) for respectful care and mental health question groupings are reported in Additional file 2: Table S1. The additional Locus of Control and Edinburgh Postnatal Depression Scale questionnaires are validated and were scored according to their respective scales [47,48,49]. Self-reported PPFP type was categorized as either more effective (sterilization, intrauterine device (IUD), sub-dermal implants, injectables) or less effective (condoms used alone, emergency contraception, or natural family planning), as supported in the literature [30]. Education level, occupation, household income, food security, and middle upper arm circumference (MUAC) were used as socioeconomic status indicators [50, 51]. A five-point Likert Scale was used for survey questions with the exception of one question on the locus of control questionnaire and one question on the Edinburgh Postnatal Depression Scale which uses the 4-point standard. RStudio 1.0.153 statistical software was used. The sample size provides 97% power to detect a change at a 95% significance level with a sample size of 640 at a 15% effect size. We applied non-parametric and parametric testing for all bivariate analysis where appropriate. The association between PPFP and most independent variables were evaluated with a Chi-square test; variables tested were categorical with more than two levels. Odds ratio and adjusted (by age group and education group) odds ratio with 95% confidence interval were performed and reported. Controlling for confounding was determined by multiple logistic regression for both the age and education groups. A p value of < 0.05 was considered statistically significant.

Results

A total of 646 survey respondents completed the baseline and follow-up questionnaires. Demographic and partner communication data were available for 94% of survey respondents (Table 1). Most respondents (50%) were 26–35 years of age and had not progressed beyond mid-secondary education (88%). Most respondents (66%) had three or fewer previous births. The majority of women reported they could discuss matters related to their pregnancy with their partner (86%).

PPFP uptake and variable correlation

PPFP uptake prevalence and related variable correlations were explored using data from the follow-up survey (Table 2). The majority of respondents (92%) did not want a pregnancy within the next year (Table 3) and 72% utilized a family planning method within 12 weeks postpartum. Of those using PPFP, 66% were using a “more effective” method. Those not using family planning were asked why they had not selected a method; 53% of those asked this question provided an answer. Half of those responding “other” cited waiting until their child was older before starting PPFP.

Association of uptake of PPFP and healthcare experience variables: respectful care, locus of control, and mental health

Women from the study sample attended 30 different primary care facilities, of which 77% were government public institutions and 17% were operated by faith-based organizations offering no “more effective” family planning methods (Table 3). The association between uptake of PPFP and health facility type was not statistically significant.

Relationships between variables related to healthcare experience and PPFP uptake were evaluated. Respectful maternity care, reported ANC attendance difficulty, locus of control, and mental health measures were not associated with PPFP uptake. ANC wait time and the individual/partner identified as the healthcare decision maker for the mother and newborn were statistically associated with PPFP uptake. Antenatal care wait time (p =  < 0.01) and reporting a partner (male) as the healthcare decision-maker (p = 0.04) were associated with PPFP uptake. The adjusted odds ratios for antenatal care wait time implies there is a difference between those taking PPFP and those not, except for those in the 41–60 min wait time group (1.50/0.84, 2.69). The adjusted odds ratios for healthcare decision making variable implies there is no difference between the two groups for those reporting the mother and partner as joint decision makers (1.06/0.66, 1.72).

Discussion

Among the postnatal Rwandan women who participated in this study, most did not want a pregnancy within one year of delivery, yet 44% failed to utilize PPFP or a “more effective” PPFP method. The aim of this study was to determine if PPFP use was influenced by the independent variables tested. These analyses suggest that ANC wait time and the mother or partner identified as the healthcare decision maker for the mother and newborn were influential elements of PPFP uptake.

Opportunities exist for increased rates of PPFP uptake

Overall, family planning use in Rwanda is accepted and the true reasons for non-use are difficult to elicit [53]. The low response rate observed for participants asked the reason for no family planning use could be due to social desirability; participants may feel hesitant to respond to this question because of favorable attitudes towards, or a feeling of pressure, to use contraceptives. This portion of the verbal survey did not provide prompted answers, another potential factor in the low response rate. Literature shows that the mode of questionnaire administration can impact data quality [54] and a “prefer not to answer” choice could have provided more insight into this absence of data.

A bolstered focus to increased sensitization to the health risks of pregnancy within two years of birth can decrease adverse RMNCH health outcomes and improve PPFP uptake [55]. The CHW network has greatly supplemented the health workforce shortages in Rwanda [17]. Family planning discussions currently take place, however, specific teaching to the health benefits of birth spacing could act as a facilitator for PPFP uptake and education of “more effective” methods. In addition, healthcare personnel can include PPFP in ANC and PNC education to supplement exposure to the health benefits of both PNC and PPFP. The continued work of family planning education, such as in the form of group care, in conjunction with an emphasis to improve RMNCH health outcomes with respect to the WHO two-year recommended birth window, can support this effort through the use of mobile technologies and bundled services [56, 57].

Partner involvement: locus of control and the healthcare decision maker

The role of the partner in PPFP uptake was highlighted in this study. Women who reported joint healthcare decision making with their partner (husband) slightly increases the odds of PPFP uptake (Adj OR 1.06), while healthcare decision making by the partner independently decreases the odds of PPFP uptake (Adj OR 0.59).Thus, the inclusion and sensitization of men in the ANC and PNC process is warranted. The importance of male partners has been called out in previous research [58] Another study in Rwanda reported similar results: women in male-headed households are 20% more likely to attend PNC and have a skilled birth attendant present at birth or deliver at a health facility [39]. It can be inferred that male buy-in for PPFP may promote better RMNCH outcomes in Rwanda. Striking a balance between male involvement while supporting women’s autonomy will be an important consideration for partner involvement.

While the formal definition of locus of control was applied consistently throughout the study, the relationship between locus of control and PPFP uptake is likely more complex than the scale can reflect. The designation of internal locus of control was allocated if the participant reported that either the mother or the mother/partner jointly made healthcare decisions. An external locus of control was designated if the partner (husband) was reported as the decision-maker. This binary scoring mechanism, mirroring the standardized scoring, was created through a Western lens; the evidence in this analysis implies that the significance and meaning in the context of Rwanda is different. This could explain the absence of statistical significance for this collated measure. The results from this study suggest when the man is identified as the decision-maker, healthcare seeking behavior is supported more than if the mother independently or jointly made the decision with her partner. Thus, the over-simplification to a correlation of decision-maker (internal locus of control) and PPFP uptake excludes important considerations across various cultures and norms. Literature suggests that locus of control in the context of care engagement and health outcomes must incorporate additional considerations to more accurately identify correlations to behavior [59, 60]. Within Rwanda’s environment of a nation of both gender progressiveness and a continued prevalence of traditional values, healthcare decision-making within partnerships should be given special consideration [61].

Generally, a gap remains in data and knowledge on the subject of faith-based organizations’ contribution to RMNCH healthcare delivery, particularly in low- and middle-income (LMIC) countries [62, 63]. Evidence exists evaluating the availability of family planning services at faith-based organizations; however, in the context of Rwanda, it is known that facilities run by some denominations do not offer “more effective” family planning methods [64]. The MOH in Rwanda has attempted to address the gap in family planning services accessibility through the establishment of health posts in these areas, however, whether health posts improve access remains unknown. No comparable research has been done on the role of faith-based organization type and resultant family planning use.

Some study limitations exist. The study sample was limited to the evaluation of women in Rwanda who access care at a public facility. However, this population is believed to be representative of Rwandan women because 85–97% of women deliver at a public healthcare facility [13]. Second, the follow-up period was extended to a 12-weeks after delivery timeline in an attempt to include participants that did not complete the questionnaire within the original 8-week time window. This extension could skew results due to recall bias and may be more representative of those who have strong health seeking behaviors. Third, sampling bias could be present as the sample includes only those who were able to present at the health facility. Lastly, some respondents may have completed the survey prior to PPFP counseling; individuals may have engaged in PPFP after completion of the survey.

Additional study insights

Despite lack of statistical significance compared against PPFP uptake, this analysis provided critical insights to the postpartum population. More than half (58%) of respondents indicated not receiving respectful care (questions detailed in A2 Table). Evidence of absence of respectful care is well documented and the results here posit additional support to the importance of health systems strengthening to reduce overworked healthcare workers [32,33,34]. Some ANC wait time adjusted odds ratios results suggested a difference between the two groups (those engaged in PPFP and those not). The odds ratio of five for the highest ANC wait time group necessitates further research. Additionally, 23% reported difficulty attending ANC [65, 66]. Both factors could have influence in postpartum follow-up and thus utilization of PPFP. However, this analysis does not illuminate a block of wait time as more influential towards PPFP uptake over others. This analysis also revealed high reports of perceived stress (66%) and postnatal depression (85%). The effects of perceived stress and postnatal depression have been well documented, including in relation to family planning use [41, 43, 44]. The timing of questionnaire administration as well as integration of identification of these patients has potential for accelerated impact on early childhood growth, among other benefits.

Conclusion

Rwanda’s great strides in RMNCH makes it a unique context in which to evaluate RMNCH health outcomes. Numerous infrastructure and health workforce developments have provided a foundation to help facilitate PPFP uptake. Although the majority of women do not want an immediate subsequent pregnancy, 44% fail to utilize PPFP or a “more effective” PPFP method. These results illustrate that a gap exists in the utilization of PPFP services. These analyses illustrated that numerous factors can influence PPFP uptake. Preliminary recommendations to improve PPFP uptake include: 1) ensure access to more effective family planning methods at all facility types; 2) improve the quality of ANC and PNC services with reduced wait time; 3) include education in maternal care curriculums on the benefits of birth spacing; and 4) create a space for the partner, and/or male involvement in RMNCH and PPFP.
