Integrated child nutrition, parenting, and health intervention in rural Liberia: A mixed-methods feasibility study.

In Liberia, children are exposed to multiple forms of adversity which can negatively impact their health and development. Research is needed to examine the feasibility and benefits of integrated interventions that can be incorporated into existing health delivery programs to simultaneously address low responsive stimulation, undernutrition, and infection. This study assessed the feasibility of an integrated intervention promoting psychosocial stimulation and improved child feeding by the provision of eggs and fish.

Prevalence and risk factors for postpartum depression and stress among mothers of preterm and low birthweight infants admitted to a neonatal intensive care unit in Accra, Ghana.

To determine the prevalence of postpartum depression (PPD) and postpartum stress (PPS) and identify associated risk factors among mothers of preterm and low birth weight (LBW) infants. We conducted a secondary analysis of data collected from 255 mothers with preterm and LBW infants admitted to the neonatal intensive care unit (NICU) at Korle-Bu Teaching Hospital, Accra, Ghana. A standardized interviewer-administered questionnaire collected data on maternal, pregnancy, birth, and infant characteristics.

Effects of iron supplements and iron-containing micronutrient powders on the gut microbiome in Bangladeshi infants: a randomized controlled trial.

Anemia is highly prevalent globally, especially in young children in low-income countries, where it often overlaps with a high burden of diarrheal disease. Distribution of iron interventions (as supplements or iron-containing multiple micronutrient powders, MNPs) is a key anemia reduction strategy. Small studies in Africa indicate iron may reprofile the gut microbiome towards pathogenic species.

Emerging Evidence and Critical Issues with the Use of Single-Drop Capillary Blood for the Measurement of Hemoglobin Concentration in Population-Level Anemia Surveys.

Accurate and precise measurement of hemoglobin concentration is critical for reliable estimations of anemia prevalence at the population level. When systematic and/or random error are introduced in hemoglobin measurement, estimates of anemia prevalence might be significantly erroneous and, hence, limit their usefulness. For decades, single-drop capillary blood has been the most common blood source used for the measurement of hemoglobin concentration in surveys, especially in low-income and middle-income countries.

Protocol for a randomised, multicentre, four-arm, double-blinded, placebo-controlled trial to assess the benefits and safety of iron supplementation with malaria chemoprevention to children in Malawi: IRMA trial.

Introduction: Approximately 40% of children aged 6-59 months worldwide are anaemic. Iron-containing multiple micronutrient powders (MNPs) and iron supplements (syrup/drops) are used to combat anaemia in children in different parts of the world. However, evidence for functional benefits of iron supplementation in children is scarce, and potential risks remain poorly defined, particularly concerning diarrhoea and malaria.

Ferric carboxymaltose versus standard-of-care oral iron to treat second-trimester anaemia in Malawian pregnant women: a randomised controlled trial.

Background: Anaemia affects 46% of pregnancies in Africa; oral iron is recommended by WHO but uptake and adherence are suboptimal. We tested a single dose of a modern intravenous iron formulation, ferric carboxymaltose, for anaemia treatment in Malawian pregnant women.

Methods: In this open-label, individually randomised controlled trial, we enrolled women with a singleton pregnancy of 13-26 weeks' gestation in primary care and outpatient settings across two regions in southern Malawi.

Prevalence of early postpartum depression and associated risk factors among selected women in southern Malawi: a nested observational study.

Background: The birth of a child should be a time of celebration. However, for many women, childbirth represents a time of great vulnerability to becoming mentally unwell, a neglected maternal morbidity. This study aimed to determine the prevalence of early postpartum depression (PPD) and its associated risk factors among women giving birth at health facilities in southern Malawi.

Supplementation With Iron Syrup or Iron-Containing Multiple Micronutrient Powders Alters Resting Brain Activity in Bangladeshi Children.

Background: Anemia and iron deficiency have been associated with poor child cognitive development. A key rationale for the prevention of anemia using supplementation with iron has been the benefits to neurodevelopment. However, little causal evidence exists for these gains.

Effects of iron supplementation on neural indices of habituation in Bangladeshi children.

Background: Iron deficiency and anemia have been associated with poor cognition in children, yet the effects of iron supplementation on neurocognition remain unclear.

Objective: We aimed to examine the effects of supplementation with iron on neural indices of habituation using auditory event-related brain potentials (ERPs).

Methods: This substudy was nested within a 3-arm, double-blind, double-dummy, individual randomized trial in Bangladesh, in which 3300 8-mo-old children were randomly selected to receive 3 mo of daily iron syrup (12.

Effectiveness of the Eggs Make Kids demand-creation campaign at improving household availability of eggs and egg consumption by young children in Nigeria: A quasi-experimental study.

Using a quasi-experimental design, our study aimed to determine the effectiveness of the 'Eggs Make Kids Sharp & Bright and Strong & Active' demand-creation campaign in Nigeria. The intervention arm received emotionally compelling radio and television advertisements about eggs, and was exposed to promotional activities and advertising about eggs at points of purchase, schools and health facilities; the comparison arm received no intervention. Children 6-59 months of age (intervention: n = 1359; comparison: n = 1485) were assessed 14 months apart.

Reliability and validity of depression anxiety stress scale (DASS)-21 in screening for common mental disorders among postpartum women in Malawi.

Background: Approximately one in five women who have recently given birth suffer from common mental disorder (CMD), particularly depression and/or anxiety. Most available CMD screening tools in most low- and middle-income countries do not screen for more than one mental health problem. Having a screening tool that is free to use, short in assessment time, and used to screen for more than one CMD is appealing in a resource-constrained setting.

Benefits and Risks of Iron Interventions in Infants in Rural Bangladesh.

Background: Universal provision of iron supplements (drops or syrup) or multiple micronutrient powders to young children in low-to-middle-income countries where anemia is prevalent is recommended by the World Health Organization and widely implemented. The functional benefits and safety of these interventions are unclear.

Methods: We conducted a three-group, double-blind, double-dummy, individually randomized, placebo-controlled trial to assess the immediate and medium-term benefits and risks of 3 months of daily supplementation with iron syrup or iron-containing multiple micronutrient powders, as compared with placebo, in 8-month-old children in rural Bangladesh.

Preanalytic and analytic factors affecting the measurement of haemoglobin concentration: impact on global estimates of anaemia prevalence.

The accuracy of haemoglobin concentration measurements is crucial for deriving global anaemia prevalence estimates and monitoring anaemia reduction strategies. In this analysis, we examined and quantified the factors affecting preanalytic and analytic variation in haemoglobin concentrations. Using cross-sectional data from three field studies (in children, pregnant and nonpregnant women), we examined the difference in haemoglobin concentration between venous-drawn and capillary-drawn blood measured by HemoCue (ie, preanalytic) and modelled how the bias observed may affect anaemia prevalence estimates in population surveys and anaemia public health severity classification across countries.

Home Fortification of Complementary Foods Reduces Anemia and Diarrhea among Children Aged 6-18 Months in Bihar, India: A Large-Scale Effectiveness Trial.

Background: Home fortification of complementary foods with multiple micronutrient powders (MNPs) is recommended to reduce child anemia in resource-poor settings. However, evidence of program effectiveness in India to guide policies and programs is lacking.

Objectives: We implemented a large-scale intervention of MNPs in Bihar, India.

Can Double Fortification of Salt with Iron and Iodine Reduce Anemia, Iron Deficiency Anemia, Iron Deficiency, Iodine Deficiency, and Functional Outcomes? Evidence of Efficacy, Effectiveness, and Safety.

Background: Anemia, iron deficiency, and iodine deficiency are problems of important public health concern in many parts of the world, with consequences for the health, development, and work capacity of populations. Several countries are beginning to implement double fortified salt (DFS) programs to simultaneously address iodine and iron deficiencies.

Objective: Our objective was to summarize the evidence for efficacy and effectiveness of DFS on the full range of status and functional outcomes and across different implementation and evaluation designs essential to successful interventions.

Balancing Safety and Potential for Impact in Universal Iron Interventions.

Almost 300 million children under 5 years of age are anemic worldwide. International policymakers recommend universal distribution of iron-based interventions - either iron supplements or iron-containing multiple micronutrient powders - to alleviate the burden of anemia in young children. When considering whether to implement universal iron interventions, it is essential to balance the putative benefits with possible risks.

Global Landscape of Malnutrition in Infants and Young Children.

Malnutrition during the first years of life has immediate adverse health consequences, including increased mortality risk, and impaired long-term health and capacities. Undernutrition is an important contributor to poor linear growth, stunting, which affects over 149 million children <5 years of age worldwide, one-third of whom live in India. Over 49 million children are wasted; yet globally, there are also 40 million overweight children.

The global effect of extreme weather events on nutrient supply: a superposed epoch analysis.

Background: To date, the effects of extreme weather events on nutrient supply within the population have not been quantified. In this study, we investigated micronutrient, macronutrient, and fibre supply changes during 175 extreme weather events within 87 countries in the year that a major extreme weather event occurred, with a targeted focus on low-income settings.

Methods: We collected data from the International Disasters Database and the Global Expanded Nutrient Supply model for the period 1961-2010, and applied superposed epoch analysis to calculate the percentage change in nutrient supply during the year of an extreme weather event relative to its historical context.

Do effects of early life interventions on linear growth correspond to effects on neurobehavioural development? A systematic review and meta-analysis.

Background: Faltering in linear growth and neurobehavioural development during early childhood are often assumed to have common causes because of their consistent association. This notion has contributed to a global focus on the promotion of nutrition during pregnancy and childhood to improve both conditions. Our aim was to assess whether effects of interventions on linear growth are associated with effects on developmental scores and to quantify these associations.

Hemoglobin concentration and anemia diagnosis in venous and capillary blood: biological basis and policy implications.

Anemia is an important public health challenge and accurate prevalence estimates are needed for program planning and tracking progress. While venous blood assessed by automated hematology analyzers is considered gold standard, most population-based surveys use point-of-care diagnostics and capillary blood to estimate population prevalence of anemia. Several factors influence hemoglobin (Hb) concentration, including human and analytic error, analysis method, and type of instrument, but it is unclear whether biological variability exists between venous and capillary blood.

Effects of increased hemoglobin on child growth, development, and disease: a systematic review and meta-analysis.

In children under 5, a hemoglobin (Hb) cutoff of 11 g/dL is recommended by the World Health Organization to define anemia, yet few studies have examined whether this cut point accurately coincides with negative functional consequences. This systematic review and meta-analysis of iron intervention and observational studies aimed to clarify the consequences of low Hb concentration in children under age 5 years on growth, development, and chronic disease (functional outcomes) across the full range of Hb values. A literature search returned 5049 studies; of these, 56 intervention and 20 observational studies fit the inclusion criteria.
