A new BOND-KIDS editorial calls for nutrition research and policy to cover children aged five to 19, combining biomarkers with the social and environmental factors shaping what young people eat.
A new editorial in The Journal of Nutrition argues that children’s nutrition cannot be understood through a narrow lens. The paper, published as part of the Biomarkers of Nutrition for Development: Knowledge Indicating Dietary Sufficiency, or BOND-KIDS, project, says research and policy have tended to focus too heavily on early childhood, even though school-age children and adolescents face distinct nutritional pressures and rapid biological change. According to the National Institutes of Health-supported project, the goal is to improve how nutrition is assessed and how programmes are designed for children aged five to 19.
The authors say a broader framework is needed because nutrition in this age group is shaped by far more than what is on the plate. As described by the National Institute of Child Health and Human Development, the project looks at biomarkers that can help researchers understand nutrient exposure, status, function and effect, while also recognising the influence of family life, schools, communities and wider social conditions. That wider view matters because food access, affordability, advertising and digital media can all influence what young people eat as they gain independence.
The editorial also highlights the fact that children and adolescents can face overlapping forms of malnutrition at the same time. Undernutrition, micronutrient deficiencies, overweight and obesity can exist within the same community, which makes one-size-fits-all approaches inadequate. The article therefore calls for nutrition policy to reflect changing needs across three stages: primary school age, early adolescence and late adolescence. That approach, the authors argue, is essential because nutritional patterns during these years can affect health later in life and may also have consequences for the next generation.
BOND-KIDS is organised around four working groups covering biology, environmental influences, assessment, and translation and implementation. The project’s reports say that structure is intended to help researchers and public health professionals develop clearer measures and more effective interventions, particularly in settings affected by food insecurity and other barriers to healthy eating. Other papers in the collection stress that an ecological approach, which brings together internal biological factors and external social and environmental ones, could make nutrition programmes more equitable and more useful in practice.
