Children's experiences of food insecurity, emotional and behavioural states in Masaka District, Uganda
Food insecurity is experienced as a psychosocial, not only nutritional, condition. • Child-centred multimodal methods reveal emotional, behavioural, and learning impacts. • Hunger-related stress is the most salient driver of negative emotional and behavioural states. • Emotional–behavioural states align with graded levels of food insecurity. • Findings support the integration of nutrition and psychosocial support in schools
Food insecurity and child mental health in Masaka District, Uganda
Food insecurity and child mental health difficulties frequently intersect, yet the mechanisms and pathways connecting them remain underexplored in resource-limited settings.

Autonomy among Indigenous women in Rural Colombia
There is limited qualitative research to support the use of the most common conceptualizations and operationalizations of women’s autonomy, especially in the Latin American context and even more so for Indigenous populations. This study uses photovoice, a photography-based Participatory Action Research method, to conduct a qualitative assessment of how female Indigenous smallholding farmers from Nariño, Colombia, define women’s autonomy and which…
Differential elements of a successful agricultural innovation scaling-up model
Worldwide, there is currently an increasing demand for an active connection between the generation of innovations and the achievement of their escalation. Between 2015 and 2018 the scaling up of three varieties of yellow potatoes was carried out in Colombia within the framework of the "More Nutritious Potatoes" project, which had results beyond the objectives and goals proposed in a period of 28 months. One of the results of the project was the d…

Food insecurity, state fragility and youth mental health
Youth in fragile settings face disproportionate risks of experiencing food insecurity and poor mental health. Cross-national evidence is lacking on the association between food insecurity and mental health in youth populations, and on state fragility as a social determinant of these experiences. We analysed data from six cycles of the Gallup World Poll (2014-2019), an annual survey that contains multi-item scales of food insecurity, mental health…

A pandemia de Covid-19 e seus entrelaçamentos com desigualdade de gênero, insegurança alimentar e apoio social na América Latina
Enquanto crises econômicas desencadeiam o aumento da insegurança alimentar (IA) e da desigualdade de gênero (DG), o apoio social tem mostrado aliviar esses impactos. No entanto, diferentemente de outros choques econômicos, a pandemia de Covid-19 incluiu no cenário de crise o isolamento social. Este estudo utilizou dados de pesquisa transversal coletados em 18 países da América Latina (AL) para avaliar as mudanças nas percepções de DG e sua associ…

Determinants of child anthropometric indicators in Ethiopia
Depending on the choice of children anthropometric indicator, different conclusions were drawn demonstrating the association between each factor to child nutritional status. Results showed child's sex, age, region, open defecation, and maternal MUAC significantly increases the risk of child anthropometric indicators. Highlighting the factors influencing child undernutrition will help inform future policies and programs designed to approach this m…
Best Practices for Developing and Validating Scales for Health, Social, and Behavioral Research
Scale development and validation are critical to much of the work in the health, social, and behavioral sciences. However, the constellation of techniques required for scale development and evaluation can be onerous, jargon-filled, unfamiliar, and resource-intensive. Further, it is often not a part of graduate training. Therefore, our goal was to concisely review the process of scale development in as straightforward a manner as possible, both to…
Major References for Learning About Healthy Eating
This study examined associations between main references Anglophone and Francophone men and women refer to when learning healthy eating, and their knowledge of best food habits (KBFH), body mass index (BMI) status, sex, age, education, and household income. Data were obtained from a 2012 Statistics Canada survey (Canadian Community Health Survey: Rapid Response, Canada’s Food Guide). A greater number of women reported high KBFH than men. Regardle…
