Introduction. Anthropometric indices are combinations of measures used to evaluate the normal growth of the child from birth; including head circumference (PC). Objetive. to measure the concordances between the WHO growth curves, the Anthro WHO and Intergrowth 21st applications, in a group of newborns (NB) diagnosed with microcephaly. Methodology. cross-sectional analytical study to 329 NBs with microcephaly from a regional hospital. The WHO reference curves were the gold parameter, comparing it with the Z score obtained with the Anthro WHO and Intergrowth 21st applications. Classified the population according to sex; the averages with standard deviation were calculated for gestational age, weight, height, head circunsfenere. The Cohen Kappa coefficient was estimated and Landis and Koch qualitative scale was used to measure the concordance. Statisticians with SPSS. Results. Of 329 births, 195 (59%) were girls. No significant differences between the means of gestational age, weight, size and CP. Between WHO / Anthro WHO Kappa = 0.813 for girls and Kappa = 0.804 for boys (Landis-Koch = almost perfect and considerable respectively). Between OMS / Intergrowth 21st Kappa = 0.030 for girls and Kappa = 0.305 for boys (Landis-Koch = mild and acceptable respectively). Conclusion. The degree of agreement between WHO gold parameter and the Anthro WHO parameter was between considerable and almost perfect, so both can be used interchangeably. Additional studies are suggested to assess the impact that the differences in agreement found between the WHO and Intergrowth 21st parameters could have.
