RT Journal Article T1 Composite indexes of anthropometric failure in children under 5 years of age in Argentina: Comparative analysis among regions: 2019–2020 A1 Salazar Burgos, Ramiro Joaquín A1 Longhi, Hugo Fernando A1 Marrodán Serrano, María Dolores AB ObjectivesComposite Index of Anthropometric Failure (CIAF) and Extended CIAF (ECIAF) allow for the identification of simultaneous presence of two or more types of malnutrition. The objective of this study was to analyze anthropometric failure in Argentinean children under 5 years old, taking into consideration regional and socioeconomic perspectives.Materials and MethodsData from the National Survey of Children and Adolescents MICS 2019–2020 were used, which included 5473 children under 5 years old of both sexes residing in the six regions of Argentina. CIAF and ECIAF excludes children not in anthropometric failure (group A) and was calculated from a percentage of children included in malnutrition categories B: wasting only; C: wasting and underweight; D: wasting, stunting, and underweight; E: stunting and underweight; F: stunting only; Y: underweight only; G: only weight excess; and H: stunting and weight excess. The data were analyzed according to region and wealth quintile.ResultsIn children aged 0–2.99 years, CIAF was 12.5% and ECIAF was 27.7%, with boys being more affected. In children aged 3–4.99 years, the rates were 9.7% and 22.3%, respectively, with girls showing a higher prevalence. The highest ECIAF was recorded in the Patagonia region (31.3%), while the highest ECIAF was observed in the poorest quintile.DiscussionThe presence of double burden of malnutrition has been observed across all regions and household income levels. Additionally, overweight has shown a higher intensity in economically prosperous regions and households, while stunting has been more prevalent in economically disadvantaged areas.
