Resumen

Objective: To compare five curves routinely used for intrauterine and extrauterine growth evaluation in preterm newborns at a public hospital in Leon, Guanajuato, and to identify those with similar diagnoses according to the reference curve (Williams) in order to determine their usefulness in clinical practice. Material and methods: This was an analytical, prospective, comparative and cross-sectional study of 100 preterm infants of both sexes born at 30 to 36 weeks of gestation without congenital malformations. We obtained birth weight and length for interpretation and we compared nutritional diagnoses between five growth curves: Babson-Benda, Fenton, Jurado-García, Battaglia-Lubchenco and Williams. Subsequently, four of the curves were compared against the reference curve (Williams). To compare variables, a χ² test was used. Results: The average age of the preterm infants was 34 ± 2 weeks of gestation, with an average birth weight of 1932 ± 699 g. With the combination among the curves, we noted that the Babson and Benda-Fenton curves showed a 50% similarity between their distributions for the diagnosis of “small for gestational age” (SGA). SGA was diagnosed with th Jurado-García, Williams, Battaglia-Lubchenco curves in 43%, 38% and 29% of infants, respectively. The comparison showed that the curves of Jurado-García and Battaglia-Lubchenco rendered a diagnosis similar to that provided by the curve of Williams. Conclusions: Our data indicate that the curves of Jurado-García and Battaglia- Lubchenco are preferable for evaluating the extrauterine and intrauterine growth of preterm infants, in addition to the reference curve provided by the WHO (Williams).
