Ethiopian women's perspectives on antenatal care and iron-folic acid supplementation: Insights for translating global antenatal calcium guidelines into practice.

After decades of global response to iron-deficiency anemia, lessons learned from antenatal iron-folic acid (IFA) supplementation can inform new micronutrient supplementation efforts. The World Health Organization recommends calcium supplementation for the prevention of preeclampsia; however, little is documented on how to design programs to integrate calcium into the standard of care. Twenty interviews with pregnant women and 22 interviews with health providers and volunteers in two districts in Ethiopia were conducted to examine how barriers and facilitators to antenatal care, IFA supplementation, and initial reactions to calcium supplements and regimen might influence adherence and inform future programs. Women viewed supplementation positively but cited lack of information on benefits and risks, forgetfulness, and inconsistent IFA supply as challenges. Though knowledge and awareness of anemia and IFA supplements were widespread, preeclampsia was mostly unknown. Some symptoms of preeclampsia were viewed as normal in pregnancy, making it difficult to convey risk to motivate supplement use. Some women viewed co-consumption of IFA and calcium as potentially harmful and were confused regarding the simultaneous risks of anemia and hypertension, understood as "low" and "high" blood levels in pregnancy. However, most said they would take both IFA and calcium supplements if provided with supplements and counseling on purpose and benefits. Strategies such as social support from families, stronger community-based counseling, and increased health care provider and community awareness of preeclampsia are critical for women to understand the benefits of supplementation and resolve confusion caused by current descriptors used for anemia and hypertension.

Adherence-Specific Social Support Enhances Adherence to Calcium Supplementation Regimens among Pregnant Women.

Background: WHO guidelines recommend integrating calcium supplementation into antenatal care (ANC) alongside iron and folic acid (IFA) to reduce maternal mortality. However, supplementation programs face multiple barriers, and strategies to improve adherence are needed. An adherence partner is someone whom pregnant women ask to support adherence at home.Objectives: This study 1) assessed adherence partner acceptability, feasibility, and associations with calcium and IFA supplement adherence and 2) examined relations between social support and adherence.Methods: This secondary analysis is from a trial integrating calcium supplementation into ANC in Kenya. ANC providers were trained on calcium and IFA supplementation and counseling, provided with behavior change materials, and given adequate supplement supplies. Pregnant women from 16 government health facilities were recruited (n = 1036); sociodemographic and adherence data were collected at baseline and at 4- to 6-wk follow-up visits. Adherence was measured with pill counts and self-reports. Culturally adapted scales measured social support in general and specific to adherence. Mixed-effects regression analyses were used to examine factors associated with adherence partners, social support, and adherence.Results: Most participants received information about adherence partners (91%) and had a partner at follow-up (89%). Participants with adherence partners reported higher adherence support (OR: 2.10; 95% CI: 1.32, 3.34). Mean ± SD adherence was high for calcium (88.3% ± 20.7%) and IFA (86.1% ± 20.9%). Adherence support was positively associated with calcium adherence at follow-up by using pill counts (OR: 2.2; 95% CI: 1.1, 2.6) and self-report data (OR: 1.9; 95% CI: 1.2, 2.9), but there was not a direct relation between adherence partners and adherence.Conclusions: Adherence support enhanced adherence to calcium supplements. The adherence partner strategy was highly acceptable and feasible but warrants further study. This research demonstrates the importance of adherence support and suggests that interventions to increase household-level support for antenatal micronutrient supplementation may be needed to implement the WHO guidelines. This trial was registered at clinicaltrials.gov as NCT02238704.

Translating formative research findings into a behaviour change strategy to promote antenatal calcium and iron and folic acid supplementation in western Kenya.

The World Health Organization now recommends integrating calcium supplements into antenatal micronutrient supplementation programmes to prevent pre-eclampsia, a leading cause of maternal mortality. As countries consider integrating calcium supplementation into antenatal care (ANC), it is important to identify context-specific barriers and facilitators to delivery and adherence. Such insights can be gained from women's and health workers' experiences with iron and folic acid (IFA) supplements. We conducted in-depth interviews with 22 pregnant and post-partum women and 20 community-based and facility-based health workers in Kenya to inform a calcium and IFA supplementation programme. Interviews assessed awareness of anaemia, pre-eclampsia and eclampsia; ANC attendance; and barriers and facilitators to IFA supplement delivery and adherence. We analyzed interviews inductively using the constant comparative method. Women and health workers identified poor diet quality in pregnancy as a major health concern. Neither women nor health workers identified pre-eclampsia, eclampsia, anaemia or related symptoms as serious health threats. Women and community-based health workers were unfamiliar with pre-eclampsia and eclampsia and considered anaemia symptoms normal. Most women had not received IFA supplements, and those who had received insufficient amounts and little information about supplement benefits. We then developed a multi-level (health facility, community, household and individual) behaviour change strategy to promote antenatal calcium and IFA supplementation. Formative research is an essential first step in guiding implementation of antenatal calcium supplementation programmes to reduce pre-eclampsia. Because evidence on how to implement successful calcium supplementation programmes is limited, experiences with antenatal IFA supplementation can be used to guide programme development.

Adherence partners are an acceptable behaviour change strategy to support calcium and iron-folic acid supplementation among pregnant women in Ethiopia and Kenya.

Antenatal calcium and iron-folic acid (IFA) supplementation can reduce maternal mortality and morbidity. Yet, even when pregnant women have a stable supply of supplements, forgetting is often a barrier to adherence. We assessed the acceptability of adherence partners to support calcium and IFA supplementation among pregnant women in Kenya and Ethiopia. Adherence partners are a behaviour change strategy to improve adherence, where pregnant women are counselled to select a partner (e.g. spouse, relative) to remind them to take their supplements. We conducted trials of improved practices, a formative research method that follows participants over time as they try a new behaviour. We provided pregnant women in Ethiopia (n = 50) and Kenya (n = 35) with calcium and IFA supplements and counselling, and suggested selecting an adherence partner. For each participant, we conducted semi-structured interviews about acceptability and adherence during four interviews over six weeks. We analysed interview transcripts thematically and tallied numerical data. In Kenya, 28 of 35 women agreed to try an adherence partner; almost all selected their husbands. In Ethiopia, 42 of 50 women agreed to try an adherence partner; half asked their husbands, others asked children or relatives. Most women who did not select adherence partners reported not needing help or not having anyone to ask. Participants reported adherence partners reminded and encouraged them, brought supplements, provided food and helped address side-effects. Almost all women with adherence partners would recommend this strategy to others. Adherence partners are an acceptable, low-cost strategy with the potential to support antenatal micronutrient supplementation adherence.

Barriers and Opportunities for Improved Exclusive Breast-Feeding Practices in Tanzania: Household Trials With Mothers and Fathers.

BACKGROUND: Effective promotion of exclusive breast-feeding (EBF) is needed to improve child nutrition and survival. OBJECTIVE: We explored barriers and facilitators to EBF in rural Tanzania and assessed parents' willingness and ability to try specific recommended EBF practices plus strategies for men to support breast-feeding. METHODS: We conducted Trials of Improved Practices in 36 households with infants <6 months. Fathers participated in focus group discussions on ways to support breast-feeding. Fathers and mothers were individually interviewed 2 and 3 times, respectively, about their willingness to try and experience with selected new practices. We analyzed data thematically. RESULTS: Common barriers to EBF were (1) use of gripe water and traditional medicines for perceived symptoms of infantile distress; (2) mothers' workloads and time away from infants, limiting availability for EBF; and (3) water given for perceived thirst. Although several mothers expressed concerns about breast-milk insufficiency, few were giving other foods. After counseling, most mothers reported breast-feeding more optimally. Some reported improved breast-milk supply. Fathers saw their roles as providing food to mothers to ensure sufficient breast-milk and encouraging new practices. Dominant gender roles and work away from home were barriers even if fathers were willing to help with household chores. Fathers mostly provided emotional support or encouraged others to help with chores. CONCLUSION: Exclusive breast-feeding promotion needs to address concerns about infantile distress and help parents develop effective soothing techniques while avoiding nonprescribed medicines. Engaging men in EBF interventions could help change social norms and facilitate men's involvement in improving breast-feeding practices.

Integrating Calcium Supplementation into Facility-Based Antenatal Care Services in Western Kenya: A Qualitative Process Evaluation to Identify Implementation Barriers and Facilitators.

BACKGROUND: In countries with low calcium intake, the WHO recommends integrating calcium supplementation into antenatal care (ANC) to reduce the risk of preeclampsia, a leading cause of maternal mortality. Current WHO guidelines recommend women take 3-4 calcium supplements plus 1 iron-folic acid supplement at separate times daily. There is limited evidence about implementing these guidelines through routine ANC. Through the Micronutrient Initiative-Cornell University Calcium (MICa) trial, we examined the effect of regimen on supplement consumption among ANC clients in western Kenya. A nested process evaluation examined factors that influence calcium supplementation delivery and uptake. OBJECTIVES: This process evaluation assessed ANC providers', pregnant women's, and family members' experiences with calcium supplementation, and investigated the feasibility and acceptability of engaging family members to support adherence. METHODS: We conducted semistructured interviews with 7 ANC providers, 32 pregnant women, and 20 adherence partners (family members who provide reminders and support), and 200 observations of ANC consultations. Interviews were transcribed, translated, and analyzed thematically. Observational data were summarized. RESULTS: ANC providers reported positive feelings about calcium supplementation, the training received, and counseling materials, but reported increased workloads. Women reported that providers counseled them on supplement benefits and managing side effects, offered reminder strategies, and provided supplements and behavior change materials. Women explained that reminder materials and adherence partners improved adherence. Most adherence partners reported providing reminders and other instrumental support to help with pill taking, which women confirmed and appreciated. Some women reported that comorbidities, concerns about being perceived as HIV positive, pill burden, unfavorable organoleptic properties, and lack of food were adherence barriers. CONCLUSIONS: Although integrating calcium into antenatal iron-folic acid supplementation was generally acceptable to ANC providers, pregnant women, and their families, calcium supplementation presents unique challenges that must be considered to successfully implement these guidelines.This trial was registered at clinicaltrials.gov as NCT02238704.

Cluster-Randomized Non-Inferiority Trial to Compare Supplement Consumption and Adherence to Different Dosing Regimens for Antenatal Calcium and Iron-Folic Acid Supplementation to Prevent Preeclampsia and Anaemia: Rationale and Design of the Micronutrient Initiative Study.

BACKGROUND: To prevent pre-eclampsia in populations with insufficient dietary calcium (Ca) intake, the World Health Organisation (WHO) recommends routine Ca supplementation during antenatal care (ANC). WHO guidelines suggest a complex dosing regimen, requiring as many as 5 pill-taking events per day when combined with iron and folic acid (IFA) supplements. Poor adherence may undermine public health effectiveness, so simpler regimens may be preferable. This trial will compare the effect of the WHO-recommended (higher-dose) regimen vs. a simpler, lower-dose regimen on supplement consumption and pill-taking behaviours in Kenyan ANC clients. DESIGN AND METHODS: This is a parallel, non-inferiority, cluster-randomized trial; we examined 16 primary care health facilities in Kenya, 1047 pregnant women between 16-30 weeks gestational age. Higher-dose regimen: 1.5 g elemental calcium in 3 separate doses (500 mg Ca/pill) and IFA (60 mg Fe + 400 µg folic acid) taken with evening dose. Lower-dose regimen: 1.0 g calcium in 2 separate doses (500 mg Ca/pill) with IFA taken as above. MEASUREMENTS: Primary outcome is Ca pills consumed per day, measured by pill counts. Secondary outcomes include IFA pills consumed per day, client knowledge, motivation, social support, and satisfaction, measured at 4 to 10 weeks post-enrolment. STATISTICAL ANALYSES: Unit of randomization is the healthcare facility; unit of analysis is individual client. Intent-to-treat analysis will be implemented with multi-level models to account for clustering. EXPECTED PUBLIC HEALTH IMPACT: If pregnant women prescribed lower doses of Ca ingest as many pills as women prescribed the WHO-recommended regimen, developing a lower-dose recommendation for antenatal Ca and IFA supplementation programs could save resources. Significance for public healthPre-eclampsia is a leading cause of maternal mortality. Based on clinical evidence of significant reduction in risk of pre-eclampsia, the WHO recommends including calcium (Ca) supplementation in antenatal care services in settings with inadequate dietary Ca intakes. A high daily amount of Ca administered in a complex dosing regimen is recommended to maximize efficacy and bioavailability. Factors such as client adherence, motivation, cost and logistical complexities may undermine effectiveness when implemented in public health programs. This cluster-randomized trial will compare Ca supplement consumption between higher and lower-dose regimens delivered through antenatal care in Kenya, integrated with iron-folic acid supplementation. If a lower-dose regimen improves adherence, women's Ca supplement consumption may be comparable to that achieved under a complex, higher-dose regimen. Evidence gained from this trial will guide public health planning for antenatal calcium supplementation programs to maximize benefits through reducing logistical, cost and adherence barriers.
