  • Marketing of commercial milk formula: A system to capture parents, communities, science, and policy

    Open AccessNigel Rollins, Ellen Piwoz et al.ARTICLEThe Lancet2023

    Despite proven benefits, less than half of infants and young children globally are breastfed in accordance with the recommendations of WHO. In comparison, commercial milk formula (CMF) sales have increased to about US$55 billion annually, with more infants and young children receiving formula products than ever. This Series paper describes the CMF marketing playbook and its influence on families, health professionals, science, and policy processe…

  • Breastfeeding: Crucially important, but increasingly challenged in a market-driven world

    Open AccessRafael Pérez-Escamilla, Cecilia Tomori et al.ARTICLEThe Lancet2023

    In this Series paper, we examine how mother and baby attributes at the individual level interact with breastfeeding determinants at other levels, how these interactions drive breastfeeding outcomes, and what policies and interventions are necessary to achieve optimal breastfeeding. About one in three neonates in low-income and middle-income countries receive prelacteal feeds, and only one in two neonates are put to the breast within the first hou…

  • More is not enough: High quantity and high quality antenatal care are both needed to prevent low birthweight in South Asia

    Open AccessSumanta Neupane, Samuel Scott et al.ARTICLEPLOS Global Public Health2023

    Antenatal care (ANC) is an opportunity to receive interventions that can prevent low birth weight (LBW). We sought to 1) estimate LBW prevalence and burden in South Asia, 2) describe the number of ANC visits (quantity) and interventions received (quality), and 3) explore associations between ANC quantity, quality and LBW. We used Demographic and Health Survey (DHS) data from Afghanistan (2015), Bangladesh (2018), India (2016), Nepal (2016), Pakis…

  • Maternal and child nutrition in the Lives Saved Tool: Results of a recent update

    Open AccessHannah Tong, Ellen Piwoz et al.ARTICLEJournal of Global Health2022

    Background: The Lives Saved Tool (LiST) is a mathematical modelling tool for estimating the survival, health, and nutritional impacts of scaling intervention coverage in low- and middle-income countries (LMICs). Various nutrition interventions are included in LiST and are regularly (and independently) reviewed and updated as new data emerge. This manuscript describes our latest in-depth review of nutrition evidence, focusing on intervention effic…

  • Nutrition data use and needs: Findings from an online survey of global nutrition stakeholders

    Open AccessAudrey J Buckland, Andrew Thorne‐lyman et al.ARTICLEJournal of Global Health2020

    BACKGROUND: There is growing global demand for country-specific information to track nutritional status and its determinants, including intervention coverage. Periodic population-based surveys form the backbone of most national nutrition information systems. However, data on the coverage of many nutrition specific and sensitive interventions remain sparse. METHODS: tests used for statistical testing. RESULTS: < 0.05). The most commonly accessed i…

  • Examining coverage, content, and impact of maternal nutrition interventions: The case for quality-adjusted coverage measurement

    Open AccessNaima T Joseph, Ellen Piwoz et al.ARTICLEJournal of Global Health2020

    BACKGROUND: Reductions in neonatal mortality remain stagnant, despite gains in health care access and utilization. Nutrition interventions during antenatal care (ANC) and in the immediate postpartum period are associated with improved neonatal outcomes. Adjusting coverage estimates for the quality of care provided yields greater insight into health system performance and potential population health benefits of accessing care. In this cross-sectio…

  • First‐food systems transformations and the ultra‐processing of infant and young child diets: The determinants, dynamics and consequences of the global rise in commercial milk formula consumption

    Open AccessPhillip Baker, Thiago Melo Santos et al.ARTICLEMaternal and Child Nutrition2020

    The inappropriate marketing and aggressive promotion of breastmilk substitutes (BMS) undermines breastfeeding and harms child and maternal health in all country contexts. Although a global milk formula 'sales boom' is reportedly underway, few studies have investigated its dynamics and determinants. This study takes two steps. First, it describes trends and patterns in global formula sales volumes (apparent consumption), by country income and regi…

  • The Impact of Marketing of Breast-Milk Substitutes on WHO-Recommended Breastfeeding Practices

    Open AccessEllen G Piwoz, Ellen Piwoz et al.ARTICLEFood and Nutrition Bulletin2015

    BACKGROUND: Suboptimal breastfeeding results in 800 000 child deaths annually. There are multiple causes of suboptimal breastfeeding, including marketing of breast-milk substitutes. OBJECTIVES: To describe sales and marketing of breast-milk substitutes and their influence on World Health Organization-recommended breastfeeding behaviors, focusing on low- and middle-income countries. METHODS: Literature review. RESULTS: Global sales of breast-milk …

  • Babies, soft drinks and snacks: A concern in low‐ and middle‐income countries

    Open AccessSandra L Huffman, Ellen G Piwoz et al.ARTICLEMaternal and Child Nutrition2014

    Undernutrition in infants and young children is a global health priority while overweight is an emerging issue. Small-scale studies in low- and middle-income countries have demonstrated consumption of sugary and savoury snack foods and soft drinks by young children. We assessed the proportion of children 6-23 months of age consuming sugary snack foods in 18 countries in Asia and Africa using data from selected Demographic and Health Surveys and h…

  • The W orld H ealth O rganization's global target for reducing childhood stunting by 2025: Rationale and proposed actions

    Open AccessMercedes De Onís, Kathryn G Dewey et al.ARTICLEMaternal and Child Nutrition2013

    In 2012, the World Health Organization adopted a resolution on maternal, infant and young child nutrition that included a global target to reduce by 40% the number of stunted under-five children by 2025. The target was based on analyses of time series data from 148 countries and national success stories in tackling undernutrition. The global target translates to a 3.9% reduction per year and implies decreasing the number of stunted children from …

  • The health of HIV‐exposed children after early weaning

    Open AccessMegan Parker, Megan E Parker et al.ARTICLEMaternal and Child Nutrition2011

    There are potential health risks associated with the use of early weaning to prevent mother-to-child transmission of human immunodeficiency virus (HIV) in resource-poor settings. Our objective was to examine growth and nutrient inadequacies among a cohort of children weaned early. Children participating in the Breastfeeding Antiretrovirals and Nutrition (BAN) Study in Lilongwe, Malawi, had HIV-infected mothers, were weaned at 6 months and fed LNS…
