Abstract

fetched live from OpenAlex

INTRODUCTION: Rapid shifts in dietary patterns, marked by increased consumption of ultra-processed foods (UPFs), are increasingly impacting the health and wellbeing of infants and toddlers in low- and middle-income countries. METHODS: Utilizing data from the Demographic and Health Surveys, other national surveys, NCD-RisC data and Euromonitor sales data, we examine changes in stunting and overweight/obesity prevalence alongside the latest data on UPF consumption trends. RESULTS: The prevalence of overweight/obesity among children and mothers is increasing rapidly while stunting rates decline slowly. Simultaneously, there is a significant increase in consumption of UPFs, especially among preschool-aged children. Increasingly, poorer households are experiencing faster rates of increase in overweight and obesity prevalence compared to wealthier households. Results highlight the early socialization of infants and toddlers to unhealthy discretionary foods including UPFs, potentially setting the stage for long-term dietary preferences that favour food with high sugar or excess sodium. CONCLUSION: There is an urgent need to address the rapid increases in UPF consumption among infants and toddlers. Options include expanding the WHO Code on marketing to protect 0-3-year-olds; creating front-of-package warning labels focusing on products for children ages 0-3 years to remove all added sugar and limit sodium in foods and beverages they consume.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
