Anemia among adolescents (ages 10-19 years) is a leading cause of morbidity and mortality in low- middle-income countries carries long-term health economic consequences. To address the issue, policymakers programmers require evidence burden anemia specific contexts, as well an understanding factors associated with this population.
Moderate acute malnutrition (MAM) affects 33 million children annually. Investments in formulations of corn-soy blended flours and lipid-based nutrient supplements have effectively improved MAM recovery rates. Information costs cost-effectiveness differences are still needed. We assessed sustained rates receiving a supplementary food: ready-to-use food (RUSF), corn soy whey blend with fortified vegetable oil (CSWB w/oil), or Super Cereal Plus amylase (SC + A) compared to Corn Soy Blend (CSB+...
Gestational weight gain (GWG) is a modifiable factor associated with maternal and child health outcomes, but the relationship between diet quality GWG has not been evaluated using metrics validated for low-income middle-income countries (LMICs).This study aimed to investigate relationships quality, socioeconomic characteristics, adequacy novel Global Diet Quality Score (GDQS), first indicator use across LMIC.Weights of pregnant women enrolled 12 27 wk gestation (N = 7577) were recorded in...
The temporal relationship between length (linear) and weight (ponderal) growth in early life is important to support optimal nutrition program design. Studies based on measures of attained size have established that wasting often precedes stunting, but such studies do not capture responsiveness previous compared with current conditions. As a result, the temporality linear ponderal relationships remain unclear. We used velocity indicators assess bidirectional children. Using monthly...
Abstract Background Multiple specialized nutritious food options are programmed for supplementation in humanitarian and development settings. However, comparative cost-effectiveness evidence is lacking, let alone incorporation of perspectives from uncompensated stakeholders. A Burkina Faso trial evaluated the Corn Soy Blend Plus w/ oil (CSB+ w/oil, reference arm), Whey w/oil (CSWB w/oil), Super Cereal (SC+), Ready-to-Use Supplementary Food (RUSF) reducing stunting wasting among children 6–23...
Iron deficiency anemia is a leading cause of morbidity among adolescents (aged 10-19 years), especially in low- and middle-income settings. Few policies programs have targeted adolescent health. Evaluate the effectiveness school-based supplementation with iron-folic acid (IFA) or multiple micronutrient supplements (MMS) addressing Burkina Faso. In this cluster-randomized trial, 3,123 secondary school students aged 10-18 years Faso were either supplemented weekly IFA, daily MMS, received...
Abstract Adolescence, a stage of growth between 10 and 19 years, is transitional period intense cognitive, emotional physical development. Though iron deficiency the leading cause morbidity mortality among this age group, nutritional interventions targeting adolescents are rare. To inform policy practice aimed at adolescent health, we established burden anaemia school‐going in Center West Burkina Faso investigated potential explanatory factors. A cross‐sectional survey was conducted January...
There is a variety of specialized nutritious foods available for use in programs targeting undernutrition, but evidence supporting the choice product limited. We compared cost-effectiveness 4 to prevent stunting and wasting children aged 6–23 mo Burkina Faso. Four geographic regions were randomly assigned 1 intervention arms: Corn-Soy Blend Plus (CSB+) programmed with separate fortified vegetable oil (the reference food), Corn-Soy-Whey (CSWB; new formulation) oil, SuperCereal (SC+),...
Introduction Adolescence is a critical time for growth and development, but this age group often neglected in research development of nutrition interventions. Despite recommendations from the WHO to provide nutrient supplements adolescents, evidence remains scarce on most effective supplementation strategy. This study aims compare weekly iron folic acid (IFA) with daily multiple micronutrient (MMSs) prevention anaemia improvement school outcomes among adolescents Burkina Faso Tanzania....
Background: Global food insecurity persists despite continued international attention, necessitating evidence-based assistance interventions that adequately address nutritional concerns. In June 2018, the US Agency for International Development’s Office of Food Peace through Aid Quality Review (FAQR) project sponsored a “Food Assistance Nutrition Evidence Summit” to share evidence relevant policy and programmatic decision-making identify critical gaps. Objective: This article presents 4...
A trial in Burkina Faso compared the cost-effectiveness of 4 specialized nutritious foods (SNFs) used to prevent stunting and wasting children aged 6-23 mo.
This analysis describes differences in household-level use of four specialized nutritious foods (SNFs) for treatment moderate acute malnutrition (MAM) children 6–59 months age Sierra Leone and explores whether these behaviors influenced recovery. From 4/2017 to 11/2018, sub-samples caregivers whose were enrolled a supplemental feeding program (SFP) MAM study randomly selected in-depth interviews in-home observations. was cluster-randomized trial 2653 with evaluating cost-effectiveness 4...
Abstract Lipid‐based nutritional supplements (LNS) and fortified blended flours (FBF) are widely used to increase the nutrient density of children's diets improve their health, but effectiveness could be modified by displacement other foods. We reanalysed data from a cost‐effectiveness trial comparing impacts on anthropometry three FBFs (Corn Soy Blend Plus [CSB+], Corn Whey [CSWB], SuperCereal [SC+]) one LNS (Ready‐to‐use Supplementary Food [RUSF]) among infants aged 7–23 months in Burkina...
Linear growth faltering is determined primarily by attained heights in infancy, but available data consist mainly of cross-sectional at each age. This study used longitudinal to test whether occurs episodically a few months very low growth, which could potentially be prevented timely intervention, or chronic condition with slower every month infancy and early childhood. Using anthropometric collected monthly between August 2014 December 2016, we investigated individual curves 5039 children...
Gestational weight gain (GWG) estimates enable the identification of populations women at risk for adverse outcomes. We described GWG distribution in low- and middle-income countries (LMICs). Demographic Health Surveys other national surveys were used to calculate average by regressing pregnant (15–49 years) time interview on their gestational age, adjusting sociodemographic factors. A mixed-effects hierarchical model was built with survey-specific as dependent variable restricted cubic...
Lipid-based nutritional supplements (LNS) and fortified blended flours (FBF) are widely used to increase the nutrient density of children's diets improve their health, but studies supplementation have shown relatively modest improvements in linear growth. One mediating factor could be displacement other foods. This study food frequency data from a trial that compared FBF lipid-based product. We hypothesized FBFs, which typically boiled fed infant as porridge, would displace starchy staples...
Seasonal cycles in climatic factors such as temperature and precipitation affect the drivers of child growth contribute to seasonal fluctuations undernutrition. Current seasonality models are limited by categorical definitions seasons that rely on assumptions about their timing fail consider magnitude. In this study, we disentangle relationship between indicators, using harmonic regression determine how is related peaks temperature, precipitation, vegetation. Longitudinal anthropometric data...
