MATERIALES Y MÉTODOS:  Estudio analítico y transversal mediante muestreo probabilístico efectuado en pacientes que concluyeron su embarazo en el Hospital San Juan de Lurigancho, Perú, durante el año 2018. Parámetros de estudio: índice de masa corporal previo al embarazo: bajo peso, normal, sobrepeso y obesidad; ganancia de peso: insuficiente, adecuada y excesiva; peso del recién nacido en gramos. La variación del peso al nacer según el índice de masa corporal previo al embarazo y la ganancia de peso se evaluaron con pruebas H de Kruskal-Wallis y ANOVA, respectivamente. También se utilizó un modelo de regresión lineal múltiple con IC95%.  RESULTADOS:  Se estudiaron 197 pacientes que iniciaron el embarazo siendo obesas o con bajo peso que tuvieron neonatos con mayor peso al nacer (3516.9 ± 480.7 g y 3564 ± 148.5 g, respectivamente). Se determinó que no existe asociación entre el índice de masa corporal previo al embarazo y el peso del recién nacido (p = 0.753). Sin embargo, el peso al nacer fue mayor en los hijos de madres con excesiva ganancia de peso (3582.9 ± 442.1 g) y menor en quienes tuvieron insuficiente ganancia de peso (3278.9 ± 447.9 g). Esto demuestra asociación significativa entre la ganancia de peso durante el embarazo y el peso al nacer (p &lt; 0.001).  CONCLUSIONES:  El índice de masa corporal previo al embarazo, de forma independiente, no se relacionó con el peso al nacer. Sin embargo, junto con la ganancia de peso durante el embarazo sí se relacionó positivamente con el peso del recién nacido.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  OBJECTIVE:  Evaluate the relationship between the pregestational body mass index and the gestational weight gain with the birth weight.  MATERIALS AND METHODS:  Cross-sectional analytical study. Through probabilistic sampling, 197 pregnant women and their neonates participated, whose delivery was attended at the San Juan de Lurigancho Hospital, 2018.The pregestational body mass index was classified as low weight, normal, overweight and obese; the gestational weight gain in insufficient, adequate and excessive; and the birth weight in grams. The variation of birth weight according to pregestational body mass index and weight gain were evaluated using the Kruskal-Wallis and ANOVA H tests, respectively. Similarly, a multiple linear regression model is required, a 95% confidence level is considered.  RESULTS:  The patients who started the pregnancy with obesity and low weight presented neonates with greater birth weight (3516.9 ± 480.7 g and 3564 ± 148.5 g, respectively), it was determined that there is not association between the pregestational body mass index and the birth weight (p = 0.753). However, the birth weight was higher in postpartum women with excessive weight gain (3582.9 ± 442.1 g) and lower in those with insufficient weight gain (3278.9 ± 447.9 g), a significant association was demonstrated between weight gain and birth weight (p &lt; 0.001).  CONCLUSION:  The pregestational body mass index, independently, was not related to birth weight. However, together with the gestational weight gain, they were positively related to the weight of the newborn.]]></p></abstract>
