Keywords:
embarazo o gestación, estado nutricional, peso pre y posgestacionalAbstract
La nutrición materna antes y durante el embarazo es reconocida como un factor determinante del resultado del nacimiento. Varios estudios han demostrado la importancia que representa el peso pregestacional y la ganancia de este durante el embarazo para evaluar el riesgo del resultado del embarazo. Los factores nutricionales maternos explican el 50% de las diferencias entre las tasas del retraso del crecimiento intrauterino que se observa en los países desarrollados respecto a los subdesarrollados. La raza explica un 25% de esas diferencias y las enfermedades endémicas, la morbilidad general y la talla materna, explican el resto.Palabras claves: Embarazo o gestación, estado nutricional, peso pre y posgestacional, riesgo, pretérmino y necesidades.
