Objective To evaluate the correlation of size, according to age, of the anthropometric growth references of Colombian indigenous children studied in Encuesta Nacional de la Situación Nutricional de Colombia 2010 -ENSIN 2010 (National Survey of Nutrition in Colombia - 2010). Method A secondary analysis of 2598 data of indigenous Colombian children under five years of age, evaluated by ENSIN in 2010, was performed. The considered variables were size according to age, gender, height, place of residence, department and socioeconomic position. The classification of the deficit in size, based on the references of the National Center for Health Statistics (NCHS) and the World Health Organization (WHO), was made by using the Z <-2 score and the Anthro software. The Kappa coefficient was estimated to assess the correlation between anthropometric categories and was classified taking into account the proposal of Altman DG. Results One in four children had a deficit in size in the light of both anthropometric references. The prevalence of the deficit was higher when using the WHO standard, increased with age and was higher in children who resided in low altitude (m). The correlation between the two references was good (kappa ≥0,688, p=0,000) for children of both genders and all ages; the exception corresponded to children of age two, since it was moderate (kappa=0,601, p=0,000). The greatest disagreement in the classification was observed in the category "tall". Conclusion According to the statistical correlation found between the two anthropometric references (WHO vs. NCHS), any reference could be used for assessment of size according to for age.
