A large-scale review of data from 18 countries, primarily in South Asia and Africa, looked at the prevalence of malnutrition in children under five years old. The study analyzed over 2.6 million records to track how many children suffered from various forms of physical growth failure.
The findings show that while the overall rate of childhood undernutrition has dropped significantly since 2005, it remains high in many regions. Specifically, about 49 percent of children were found to have a composite index of anthropometric failure. The data also showed that children in rural areas and those living in the poorest households face higher risks.
Additionally, children whose mothers had no formal education were more likely to experience undernutrition. Because this study is based on observational data, it shows links between location, wealth, and nutrition rather than direct causes. These results highlight that while progress is being made, specific groups still need more support.
