Child Malnutrition

Globally, populations are experiencing increases in the double burden of malnutrition, commonly defined as maternal overweight/obesity and child stunting in the same household. This study will evaluate an integrated intervention combining food supplementation for pregnant and postpartum women and their infants with behavioral counseling to promote healthy maternal weight, nutrition, physical activity, and infant feeding practices. The goal is to reduce the double burden of malnutrition in rural Indigenous communities in Guatemala.

This cluster-randomized crossover trial evaluates the impact of two different packaging formats for small-quantity lipid-based nutrient supplements (SQ-LNS) on adherence and acceptability among caregivers of young children in Northern Ghana. SQ-LNS are a proven intervention for reducing child malnutrition, but optimizing packaging formats may improve adherence and scalability. Eight health facilities participating in growth monitoring services will each receive both formats: a 1-day sachet (20g daily) and a 7-day bulk container (140g weekly), with the order of delivery randomized. Each packaging format will be distributed for one month before cross-over. The primary outcomes are adherence (measured through caregiver self-report and sachet counts) and acceptability (assessed via caregiver interviews). Secondary outcomes include caregiver preference, ease of use, and qualitative insights into feeding practices, beliefs, and packaging usability. This implementation research study uses a convergent mixed-methods design, integrating quantitative adherence and acceptability data with in-depth interviews and structured observations to inform real-world program implementation. Findings will guide policy and program decisions for integrating SQ-LNS into child health platforms in Ghana and other low-resource settings.

In last decades, a change in dietary habits has been observed in industrialized countries characterized by a drastic increase in the consumption of ultra-processed foods (UPF, Ultra-Processed Foods). As defined by the NOVA classification, UPFs are industrial formulations of food substances added with colourings, flavourings, emulsifiers, thickeners and other additives. Among the main compounds of UPFs are the advanced glycation end-products (AGEs). Increasing evidence suggests an association between dietary exposure to AGEs and the development of chronic non-communicable diseases, such as obesity and allergies, in the general population, through increased oxidative stress and inflammation. Preliminary evidence suggests that a maternal diet rich in AGEs during pregnancy and lactation could negatively influence the composition of breast milk and have a negative impact on the infants health. However, data regarding the presence of derivatives of UPFs in breast milk are not available. The UFIM (Ultraprocessed Foods In Breast Milk) study aims at evaluate the presence of UPFs-derivatives compounds in breast milk.

This study will focus on a new community health worker (CHW) program called 'Flourish', which is implemented by Philippine non-governmental organization (NGO) International Care Ministries (ICM). ICM's core program is 'Transform', which is a poverty alleviation program that focuses on households living in ultra-poverty (less than 0.50 United States dollars (USD) per person per day). Transform leverages local community networks to identify 30 participants from the most marginalized households in the community. ICM then provides these participants with 15 weeks of health and livelihood education, as well as with health interventions, including childhood malnutrition treatment. In ICM's Flourish program, one of the 30 participants in each Transform program is nominated by their peers to become an ICM-supported CHW. The CHWs will not only provide health services after the conclusion of the Transform program for their fellow Transform participants' households, but they will also serve an additional 50+ households in their communities. These additional 'non-Transform' households will be identified by asking the Transform participants to nominate peers in their social networks that share similar socioeconomic backgrounds and whose households are perceived to also benefit from CHW services. The primary aim of this research is to assess the impact of CHWs on the prevalence of acute childhood malnutrition in hard-to-reach households within low-income communities. The investigators hypothesize that this study will show that CHWs are able to reduce the prevalence of acute childhood malnutrition in hard-to-reach households within low-income communities.

The goal of this study is to evaluate the efficacy of microbiota-directed food in comparison to zinc with micronutrient powder and Khichuri on changes in circulating immune cells (monocytes, T cells, B cells, and NK cells) in malnourished children after recovery from acute infection. The study aims to answer the research question: Does microbiota-directed food (MDF) compared to zinc with micronutrient powder (MNP) and Khichuri therapy enhance immunity in children with severe acute malnutrition? The researcher will compare the effectiveness of microbiota-directed food (MDF) versus zinc with micronutrient powder (MNP) and Khichuri therapy to see if MDF enhances immunity in severely malnourished children. Severely malnourished children will: * Receive microbiota-directed food (MDF) or zinc with micronutrient powder (MNP) and Khichuri every day for 12 weeks. * Phenotyping of circulating immune cells (NK cells, T cells, B cells) will be conducted using flow cytometry and fluorescence-activated cell sorting techniques.
