Para evaluar la relación entre el índice de masa corporal (IMC) materno al comienzo del embarazo y la antropometría del recién nacido (RN), se estudiaron 105 binomios (madre-recién nacidos) en una Maternidad pública de Valencia, Venezuela (1998-2002). Se registró el peso y talla en mujeres adultas que acudieron al primer control prenatal entre las semanas 10 y 15 de gestación y su IMC se caracterizó a través de la referencia de Atalah (Bajo peso, Normalidad y Sobrepeso). Sus hijos (RN a término) fueron evaluados calculando su edad gestacional por el método de Capurro y se registró su peso, talla y circunferencia cefálica, con caracterización nutricional a través de una referencia venezolana. Se consideró RN "pequeño para edad gestacional" (PEG) aquel con peso al nacer £ percentil 10 y "grande para edad gestacional" (GEG) aquel con peso ³ percentil 90. Para las comparaciones de grupo se utilizó el análisis de varianza de un factor (ANOVA) y la prueba Post Hoc de Tukey. Se observó un 41,9% de madres en "Bajo peso" y un 13,4% de RNPEG. Hubo diferencias significativas (pSummary To assess the relationship between maternal body mass index (BMI) at early gestation and the newborns’ anthropometry, 105 mother-infant dyads from a public Maternity Hospital in Valencia Venezuela, were studied during 1998-2000. Weight and height of adult women between 10 and 15 weeks of gestation were used to calculate BMI according to Atalah’s reference (Low weight, Normal, Over weight). Term newborns were assessed using gestational age calculated according to the Capurro method. Their weight, height, and head circumference were recorded, and were characterized using a Venezuelan reference. Newborns whose birth weight (BW) was £ 10th percentile were considered "small for gestational age" (SGA), and those with BW³ 90th percentile as "large for gestational age" (LGA). One-way ANOVA and Tukey’s Post Hoc test were used for group comparisons. There were 41.9% of "low weight" mothers, and 13.4% of SGA newborns. There were differences in the newborns’ weight and height according to "Low weight" maternal BMI with "Normal" and "Over weight" maternal BMI (p |
