LAGOS S, Rudecindo; BUSTOS M, Luis  and  ORELLANA C, Juan José. EVALUACIÓN NEONATAL DEL CRECIMIENTO INTRAUTERINO DE RECIÉN NACIDOS EN HOSPITAL REGIONAL DE TEMUCO: COMPARACION CON TRES ESTÁNDARES NACIONALES. Rev. chil. obstet. ginecol. [online]. 2009, vol.74, n.4, pp.209-216. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262009000400002.

Background: Birth weight, length, skull perimeter and neonatal ponderal index, according to gestational age, are important indicators of fetal growth. WHO recommend, build local standard for better assessment in fetal growth changes. Objective: To determine local neonatal intrauterine growth curve according to gestational age and birth weight, and compared with other Chilean standards. Method: A cross-sectional study in 57,470 births, born between the 24th and 42th weeks of gestation (Temuco-Chile, 1994-2007). Percentil distribution (p3, p5, p10, p50 and p90) of neonatal variables (weight, height, ponderal index and skull perimeter) were calculated. Results: Our curve in comparison with the others Chilean fetal growth standard (fetal growth curve of Juez, Alarcón, and González, respectively) show differences in the population under p10 (8.2%, 7.8% and 4.2%, respectively), and over p90 (14.5%, 15.2% and 17.4%, respectively). Conclusion: It was observed significant differences in fetal growth classifications, between Temuco standard with the others 3 Chilean curves, especially with the national standard who include not selected obstetric population.

Keywords : Fetal growth; neonatal anthropometry; gestational age.
