Comentario al artículo “Factores de riesgo asociados a parto pretérmino en un hospital de segundo nivel”

Preterm birth is a worldwide problem with a high economic impact and morbimortality in children. Therefore, the literature has focused on finding modifiable factors associated with this entity, such as the study "Risk factors associated with preterm birth in a second level hospital," which concluded that "100% of risk factors associated with preterm birth are potentially preventable”. Our team reanalyzed the results and found in the regression model that premature rupture of membranes was the only variable associated with preterm birth. This variable is not 100% preventable, so the results found are different from the authors' conclusions.
