Approaches to Address the Anemia Challenge

Anemia is a multifactorial condition; approaches to address it must recognize that the causal factors represent an ecology consisting of internal (biology, genetics, and health) and external (social/behavioral/demographic and physical) environments. In this paper, we present an approach for selecting interventions, followed by a description of key issues related to the multiple available interventions for prevention and reduction of anemia. We address interventions for anemia using the following 2 main categories: 1) those that address nutrients alone, and, 2) those that address nonnutritional causes of anemia. The emphasis will be on interventions of public health relevance, but we also consider the clinical context. We also focus on interventions at different stages of the life course, with a particular focus on women of reproductive age and preschool-age children, and present evidence on various factors to consider when selecting an intervention-inflammation, genetic mutations, nutrient delivery, bioavailability, and safety. Each section on an intervention domain concludes with a brief discussion of key research areas.

Effect and Challenges of an Integrated Nutrition-Intervention Package Utilization among Pregnant Women and Lactating Mothers in Rwanda: An Exploratory Qualitative Study

Background

Malnutrition among pregnant women and lactating mothers remains an issue of public health concern in developing countries. The Gikuriro program, an integrated nutrition-specific and nutrition-sensitive intervention, was implemented in 5 districts of Rwanda for 5 y to address this problem. Postprogram quasi-experiments showed significant effect of the intervention on maternal and child undernutrition. Notwithstanding, there was a need for a qualitative study to explore the views of the beneficiaries and implementers regarding its benefits, challenges, and limitations to inform future interventions.

Objective

This study aimed to explore the effect and challenges of an integrated nutrition-intervention program among pregnant women and lactating mothers.

Methods

This was a qualitative study involving 25 community health officers and 27 nutritionists as key informants and 80 beneficiaries in 10 focus group discussions. All interviews and group discussions were audio-recorded, transcribed verbatim, translated into English, and double coded. A deductive and inductive content analysis approach was used with the help of ATLAS.ti, version 9.15.

Results

The study identified several positive effects, such as improved knowledge and skills on nutrition, a positive mindset toward a balanced diet, perceived improved nutrition, and economic independence among pregnant women and lactating mothers. However, some of the main obstacles of the integrated nutrition intervention were lack of awareness of the program, negative beliefs, poverty, lack of spousal support, and time constraints. Moreover, the study identified a main limitation: the lack of inclusiveness for all social categories.

Conclusions

This study demonstrates that integrated nutrition interventions have perceived positive effect on nutrition; however, such interventions may face some challenges and limitations. These findings suggest that, apart from contributing to the body of evidence for scale up of such interventions in resource-limited settings, economic challenges and misconceptions have to be addressed to maximize the effect of such interventions.

Effect of integrated nutrition-sensitive and nutrition-specific intervention package on maternal malnutrition among pregnant women in Rwanda

Maternal undernutrition remains a major public health concern in Rwanda despite significant gains and progress. An integration of nutrition‐specific and nutrition‐sensitive interventions was implemented in five districts of Rwanda to improve maternal and child nutrition. The package included nutrition education and counselling, promotion of agricultural productivity, promotion of financial literacy/economic resilience and provision of Water, Hygiene and Sanitation services. However, there is limited evidence about the effect of such interventions in reducing maternal undernutrition. A postintervention quasi‐experimental study was conducted among pregnant women to determine the effect of the integrated intervention on their nutritional status. It was carried out in two intervention districts, namely Kicukiro and Kayonza, and two control districts, namely Gasabo and Gisagara between November 2020 and June 2021. Five hundred and fifty‐two women were recruited for the intervention arm, while 545 were recruited for the control arm. Maternal undernutrition was defined as either having low mid‐upper arm circumference (<23 cm) during delivery or low body mass index (<18.5 kg/m²) in the first trimester or both. A multivariable logistic regression model was used to assess the effect of the integrated interventions. The prevalence of maternal undernutrition was significantly lower in the intervention group compared with the control group (4.7% vs. 18.2%; p < 0.001). After controlling the potential confounders, the risk of maternal undernutrition was 77.0% lower in the intervention group than in the control group [adjusted odds ratio= 0.23; 95% confidence interval = 0.15–0.36; p < 0.001]. Further studies are therefore recommended to establish causation and inform the potential scale‐up of these interventions nationally in Rwanda.

Empirical evidence on the effect of integrated nutrition‐specific and nutrition‐sensitive interventions on maternal undernutrition is limited as existing studies are mainly directed at the effectiveness of nutritional interventions on improving child nutritional status.

The results indicated that the integrated nutrition‐specific and nutrition‐sensitive intervention package was significantly associated with low maternal undernutrition.

This study adds more evidence to the 2008, 2013 and 2021 Lancet Series regarding the proposed effectiveness of integrated nutrition‐sensitive and nutrition‐specific interventions.

Further research should focus on follow‐up randomized controlled trials and the cost‐effectiveness of these integrated nutrition‐specific and nutrition‐sensitive interventions.

Effect of an Integrated Package of Nutrition Behavior Change Interventions on Infant and Young Child Feeding Practices and Child Growth from Birth to 18 Months: Cohort Evaluation of the Baduta Cluster Randomized Controlled Trial in East Java, Indonesia

The need for a multisectoral approach to tackle stunting has gained attention in recent years. Baduta project aims to address undernutrition among children during their first 1000 days of life using integrated nutrition-specific and nutrition-sensitive interventions. We undertook this cohort study to evaluate the Baduta project’s effectiveness on growth among children under 2 years of age in two districts (Sidoarjo and Malang Districts) in East Java. Six subdistricts were randomly selected, in which three were from the intervention areas, and three were from the control areas. We recruited 340 pregnant women per treatment group during the third trimester of pregnancy and followed up until 18 months postpartum. The assessment of breastfeeding and complementary feeding practices used standard infant and young child feeding (IYCF) indicators in a tablet-based application. We measured weight and length at birth and every three-months after that. The enumerators met precision and accuracy criteria following an anthropometry standardization procedure. Among the breastfed children, the percentage of children who achieved the minimum dietary diversity score (DDS) and minimum acceptable diet (MAD) was higher for the intervention group than the comparison group across all age groups. The odd ratios were 3.49 (95% CI: 2.2–5.5) and 2.79 (95% CI: 1.7–4.4) for DDS and 3.49 (95% CI: 2.2–5.5) and 2.74 (95% CI: 1.8–5.2) for MAD in the 9–11 month and 16–18-month age groups, respectively. However, there was no significant improvement in growth or reduction in the prevalence of anemia. The intervention was effective in improving the feeding practices of children although it failed to show significant improvement in linear growth of children at 18 months of age.

Perspective: Integration to Implementation (I-to-I) and the Micronutrient Forum-Addressing the Safety and Effectiveness of Vitamin A Supplementation

An ongoing challenge to our ability to address the role of food and nutrition in health promotion and disease prevention is how to design and implement context-specific interventions and guidance that are safe, efficacious, and avoid unintended consequences. The integration to effective implementation (I-to-I) concept is intended to address the complexities of the global health context through engagement of the continuum of stakeholders involved in the generation, translation, and implementation of evidence to public health guidance/programs. The I-to-I approach was developed under the auspices of the Micronutrient Forum and has been previously applied to the question of safety and effectiveness of interventions to prevent and treat nutritional iron deficiency. The present article applies the I-to-I approach to questions regarding the safety and utility of large-dose vitamin A supplementation programs, and presents the authors' perspective on key aspects of the topic, including coverage of the basic and applied biology of vitamin A nutrition and assessment, clinical implications, and an overview of the extant data with regard to both the justification for and utility of available intervention strategies. The article includes some practical considerations based on specific country experiences regarding the challenges of implementing vitamin A-related programs. This is followed by an overview of some challenges associated with engagement of the enabling communities that play a critical role in the implementation of these types of public health interventions. The article concludes with suggestions for potential approaches to move this important agenda forward.

Evidence Synthesis and Translation for Nutrition Interventions to Combat Micronutrient Deficiencies with Particular Focus on Food Fortification

Over two billion people suffer from micronutrient deficiencies. Food fortification is a prominent nutrition intervention to combat such deficiencies; however, its effectiveness, risks, and ethical implications vary depending on the contexts associated with the deficiency it is addressing and the circumstances with its implementation. The aim of this research was to analyse the profile of nutrition interventions for combating micronutrient deficiency with particular focus on food fortification reported in existing systematic reviews (SRs), guidelines and policy statements, and implementation actions for nutrition. A review of secondary data available from online databases of SRs, guidelines and policy statements, and implementation actions, categorised as either "nutrition-specific interventions" (NSpI) or "nutrition-sensitive interventions" (NSeI), was conducted. Currently, there is evidence available for a diversity of food fortification topics, and there has been much translation into action. Indeed, food fortification and micronutrient supplementation interventions and NSpI more broadly dominate the profile of interventions for which there were SRs, guidelines, and policy statements available. The findings demonstrate that, although there is a rational linear relationship between evidence synthesis and translation in formulating policy and actions to combat micronutrient deficiencies, the various nutrition interventions available to help combat micronutrient deficiencies are not equally represented in the evidence synthesis and translation processes. Effective and safe policies and actions to combat micronutrient deficiencies require decisions to be informed from a body of evidence that consists of evidence from a variety of interventions. Into the future, investment in making available a higher number of SRs, guidelines and policy statements, and actions of NSeI is indicated.
