Multiple-micronutrient supplementation: Evidence from large-scale prenatal programmes on coverage, compliance and impact

Cost-Effectiveness Analysis of Multiple Micronutrient Supplementation (MMS) Compared to Iron Folic Acid (IFA) in Pregnancy: A Systematic Review

Introduction

Multiple micronutrient deficiencies might increase the adverse outcome during pregnancy and after birth. Considering the WHO recommendations since 2016 and scientific evidence from previous studies that multiple-micronutrient supplementation (MMS) is more effective than iron folic acid (IFA) in improving pregnant women's health, it is imperative to conduct an economic evaluation to assess the cost-effectiveness of MMS compared with IFA.

Methods

We conducted a systematic review from PubMed and Scopus to identify the cost-effectiveness analyses of MMS compared to IFA for pregnant women up to January 2024. Data extraction included specific study characteristics, input parameters, cost elements, cost-effectiveness results, and key drivers of uncertainty. This systematic review adhered to The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

Results

After removing 111 duplicates and following the screening process on the title and abstract of 1201 records, resulting in 125 full-text articles assessed for eligibility, a total of 5 studies fulfilled the inclusion criteria and were included in the review. All included studies were from low- and middle-income countries and demonstrated that MMS compared to IFA for pregnant women is cost-effective and even very cost-effective in some countries. All included studies implemented cost-effectiveness analysis (CEA) and estimated its cost-effectiveness using incremental cost-effectiveness ratio (ICER) per disability-adjusted life years (DALY) averted. Results suggested that the transition from IFA to MMS was cost-effective. The range of ICER per DALY averted in this study is USD 3.62 to USD 1024, depending on the scenario. Overall, the main determinant influencing cost-effectiveness was the cost of MMS procurement.

Conclusion

Our findings highlight that transitioning from IFA to MMS in certain conditions has been proven cost-effective, emphasizing this intervention's economic viability. MMS price and micronutrient deficiency-related disease burden are important determinants in assessing cost-effectiveness.

Vitamins and minerals, education, and self-care need during preconception to 1000 days of life in Southeast Asia: An expert panel opinion

Addressing maternal malnutrition and its drivers is paramount in Southeast Asia. This article summarizes the key clinical learnings and evidence-based opinions from the experts to understand the need for vitamins and minerals supplementation, education, and self-care from preconception to the first 1000 days of life, which warranted further attention since COVID-19 pandemic. Evidence describing the importance of vitamins and minerals during preconception, pregnancy, and lactation stages was identified using literature databases. A pre-meeting survey was conducted to determine the current practices and challenges in Southeast Asia. Based on the literature review and clinical experience, experts defined the topics, and an online meeting was held on 13th July 2021. During the meeting, nine experts from Southeast Asia provided evidence-based opinion on the vitamins and minerals supplementation, education, and self-care need during preconception, pregnancy, and lactation stages. The expert opinions underpin maternal malnutrition as a prevalent issue and discuss appropriate interventions and prevention strategies for women in Southeast Asia. The recent pandemic further impacted nutrition status, pregnancy, and neonatal health outcomes. The expert panel emphasized a need to improve existing inadequacies in education, self-care, and social support, and discussed the role of policymakers in addressing the barriers to dietary changes. As inadequacies in regular vitamins and minerals supplementation, education, and self-care for women of reproductive age implicate maternal and child health outcomes, there is an urgent need for addressing malnutrition concerns in this population. Thus, a strong partnership between policymakers, healthcare professionals, and other relevant sectors is required.

Micronutrient intake and associated factors among pregnant women in East Africa: Multilevel logistic regression analysis

BACKGROUND

Micronutrient deficiencies during pregnancy pose significant public health issues, considering the potential for negative consequences not only during pregnancy but also throughout life. Anemia in pregnant women is becoming a significant problem in developing countries, with scientific evidence indicating that 41.8 percent of women worldwide suffer from anemia. As a result, investigating the pooled prevalence and factors associated with micronutrient intake among pregnant women in East Africa is critical to alleviate the burden of micronutrient deficiency among pregnant women.

METHOD

The pooled prevalence of micronutrient intake with a 95% Confidence Interval (CI) was reported and presented in a forest plot for East Africa Countries using STATA version 14.1. Intra-class Correlation Coefficient (ICC), Likelihood Ratio (LR) test, Median Odds Ratio (MOR), and deviance (-2LLR) values were used for model comparison and fitness. Adjusted Odds Ratios (AOR) with a 95% Confidence Interval (CI) and p-value ≤0.05 in the multilevel logistic model were used to declare significant factors associated with micronutrient intake.

RESULT

The pooled prevalence of micronutrient intake in East African countries was 36.07% (95% CI: 35.82%, 36.33%). In the multilevel logistic regression model, women from the highest wealth quintile were 1.06 [AOR = 1.09, 95%CI: 1.00, 1.11] more likely to take micronutrients compared to their counterparts. Mothers who attained primary education, secondary education, and tertiary education had 1.20 times [AOR = 1.20, 95% CI: 1.15, 1.26], 1.28 times [AOR = 1.28, 95% CI: 1.19, 1.36] and 1.22 times [AOR = 1.22, 95% CI: 1.07, 1.38] more likely take micronutrient compared to mothers who attained no education, respectively.

CONCLUSION

The overall prevalence of micronutrient intake in East Africa was low. Only 36% of the study participants had micronutrient intake practice. Socioeconomic factors (education level, and household wealth status) have been shown to influence micronutrient intake. Therefore, it is necessitates the continuation of ongoing projects as well as the development of fresh ones that concentrate on these variables and include effective treatments and programs, especially among underprivileged and vulnerable populations.

Integrating Women and Girls' Nutrition Services into Health Systems in Low- and Middle-Income Countries: A Systematic Review

Women's nutrition has been highlighted as a global priority to ensure the health and well-being of both them and future generations. This systematic review summarises the available literature on the integration of nutrition services for girls and women of reproductive age (GWRA) into existing public health systems across low- and middle-income countries, as well as any barriers to integration. We searched PubMed and Cochrane Database of Systematic Reviews for articles published since 2011 according to eligibility criteria. A total of 69 articles were included. Evidence suggested that several services for GWRA are well integrated into public health systems, including antenatal care services, nutrition education and counselling, and micronutrient supplementation programmes. However, there was limited evidence on the integration of family planning, adolescent health, and reproductive health services. Barriers to integration fell into five main themes: lack of training and capacity building, poor multisectoral linkages and coordination, weak advocacy, lack of M&E systems, and inequity. We identified a lack of evidence and services for non-pregnant GWRA and for women postpartum. Addressing barriers to integration and gaps in nutrition services for GWRA would increase service coverage and contribute to improving health outcomes for GWRA and future generations.

All Children Thrive: Integration of Nutrition and Early Childhood Development

Building on the successes of child survival, we review the evidence needed to ensure both that children who survive also thrive and that recommendations promote equity, with no child left behind. To illustrate the critical roles played by nutrition and child development, we revise the Conceptual Framework for the Causes of Malnutrition and Death and the Nurturing Care Framework to create the Conceptual Framework of All Children Surviving and Thriving. The revised framework highlights the goals of child growth and development, supported by health, nutrition, learning, responsive caregiving, and security and safety. We review the challenges posed by undernutrition, stunting, micronutrient deficiencies, overweight, and children not reaching their developmental potential. Although integrated nutrition-childhood development interventions have shown promising effects, most have not been implemented at scale. Implementation science that investigates how and why integrated interventions work in real life, along with the acceptability, feasibility, cost, coverage, and sustainability of the interventions, is needed to ensure equity for all children thriving.

Multiple micronutrient supplements in pregnancy: Implementation considerations for integration as part of quality services in routine antenatal care. Objectives, results, and conclusions of the meeting

Health promotion, screening, diagnosis, and disease prevention are essential services of quality routine antenatal care for pregnant adult and adolescent women. Supplementation programmes in pregnancy, generally implemented in the context of antenatal care services, have had less than optimal results in many countries, generally attributed to limited access, low coverage, and reduced adherence to the recommended regimens and counselling. The World Health Organization Department of Nutrition for Health and Development, in collaboration with the United Nations Children's Fund and Nutrition International, convened the technical consultation "Multiple micronutrient supplements in pregnancy: Implementation considerations for successful incorporation into existing programmes." The objectives of the technical consultation were to (a) examine implementation experiences of micronutrient supplementation interventions in pregnant women, lessons learnt, and best practices; (b) discuss programmatic and technical considerations of interventions on multiple micronutrient supplementation in pregnant women in low-, middle-, and high-income countries; and (c) identify implementation considerations that can be useful to scaling up efforts by national policymaker and their advisors considering multiple micronutrient supplementation in pregnant women as part of existing antenatal care programmes as well as other delivery platforms. The consultation was based on presentations of background papers, case studies, and plenary discussions. Country representatives were asked to discuss the context of micronutrient supplementation for their countries and share implementation challenges they faced. This paper provides the background and rationale of the technical consultation, synopsises the presentations, and provides a summary of the main considerations and conclusions reached during plenary discussions.

Review of the evidence regarding the use of antenatal multiple micronutrient supplementation in low- and middle-income countries

Inadequate micronutrient intakes are relatively common in low- and middle-income countries (LMICs), especially among pregnant women, who have increased micronutrient requirements. This can lead to an increase in adverse pregnancy and birth outcomes. This review presents the conclusions of a task force that set out to assess the prevalence of inadequate micronutrient intakes and adverse birth outcomes in LMICs; the data from trials comparing multiple micronutrient supplements (MMS) that contain iron and folic acid (IFA) with IFA supplements alone; the risks of reaching the upper intake levels with MMS; and the cost-effectiveness of MMS compared with IFA. Recent meta-analyses demonstrate that MMS can reduce the risks of preterm birth, low birth weight, and small for gestational age in comparison with IFA alone. An individual-participant data meta-analysis also revealed even greater benefits for anemic and underweight women and female infants. Importantly, there was no increased risk of harm for the pregnant women or their infants with MMS. These data suggest that countries with inadequate micronutrient intakes should consider supplementing pregnant women with MMS as a cost-effective method to reduce the risk of adverse birth outcomes.

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.

Use of dietary supplements by pregnant women in Colombia

Background

During pregnancy, the need for certain nutrients increases. This study assessed the prevalence and socio-demographic factors associated with dietary supplement use in a representative sample of pregnant women in Colombia.

Method

Data for this study were obtained from a cross-sectional, nationally representative survey (ENSIN, 2010). A total of 1856 pregnant women, 13–49 years of age, were recruited. The use of prenatal dietary supplements (Vitamins A, C or E) was treated as a binary outcome (used at some time or never sued during pregnancy when prescribed by a doctor) in multinomial analyses. Sociodemographic data and associated factors were assessed by computer-assisted personal interview technology.

Results

Of the sample, 1123 women (68.6%) reported taking prenatal dietary supplements at some stage during their pregnancy. Most users had a high socioeconomic level (79.5%), were in their third trimester of pregnancy (79.5%), were 30–49 years of age (74.0%), and lived in the central region of Colombia (73.8%). The multivariate logistic regression showed that third trimester of pregnancy (OR 6.2;95% CI 4.0 to 9.3), high educational level (OR 2.3; 95% CI 1.5 to 3.4), high socioeconomic level -SISBEN IV or more- (OR 2.0; 95% CI 1.4 to 2.8), residence in the Atlantic region (north) (OR 2.6; 95% CI 1.7 to 3.6), Eastern region (OR 2.0; 95% CI 1.3 to 3.1), central region (OR 2.6; 95% CI 1.7 to 3.9), Pacific region (west) (OR 1.5; 95% CI 1.0 to 2.3), and belonging to the mestizo (others) ethnic group (OR 1.2; 95% CI 1.0 to 2.6), were all associated with a higher probability of dietary supplement intake.

Conclusion

The prevalence of prenatal dietary supplements in pregnant women in Colombia was found to be substantial. The variables significantly associated with their use were educational level, socioeconomic level, trimester of pregnancy, geographic level and ethnic group. These results indicate the necessity of implementing new health policies that guarantee uniform access to nutritional supplements for all population sectors, especially in countries, such as Colombia, who are currently undergoing a process of nutritional transition.

Multiple-micronutrient supplementation: Evidence from large-scale prenatal programmes on coverage, compliance and impact

Micronutrient deficiencies during pregnancy pose important challenges for public-health, given the potential adverse outcomes not only during pregnancy but across the life-course. Provision of iron-folic acid (IFA) supplements is the strategy most commonly practiced and recommended globally. How to successfully implement IFA and multiple micronutrient supplementation interventions among pregnant women and to achieve sustainable/permanent solutions to prenatal micronutrient deficiencies remain unresolved issues in many countries. This paper aims to analyse available experiences of prenatal IFA and multiple micronutrient interventions to distil learning for their effective planning and large-scale implementation. Relevant articles and programme-documentation were comprehensively identified from electronic databases, websites of major-agencies and through hand-searching of relevant documents. Retrieved documents were screened and potentially relevant reports were critically examined by the authors with the aim of identifying a set of case studies reflecting regional variation, a mix of implementation successes and failures, and a mix of programmes and large-scale experimental studies. Information on implementation, coverage, compliance, and impact was extracted from reports of large-scale interventions in Central America, Southeast Asia, South Asia, and Sub-Saharan Africa. The WHO/CDC Logic-Model for Micronutrient Interventions in Public Health was used as an organizing framework for analysing and presenting the evidence. Our findings suggest that to successfully implement supplementation interventions and achieve sustainable-permanent solutions efforts must focus on factors and processes related to quality, cost-effectiveness, coverage, utilization, demand, outcomes, impacts, and sustainability of programmes including strategic analysis, management, collaborations to pilot a project, and careful monitoring, midcourse corrections, supervision and logistical-support to gradually scaling it up.
