Los investigadores de la Universidad Stanford en Palo Alto (Estados Unidos) usaron los datos del registro de certificados de nacimiento y muerte de California de tres millones de niños sin anomalías congénitas para examinar la influencia del momento del nacimiento y el riesgo de muerte neonatal.
La mortalidad media fue de 2,08 bebés muertos por cada 1.000 nacidos vivos, pero la tasa fue significativamente más baja entre los que nacieron durante el día (1,88/1000) que durante la tarde-noche (2,37/1000) y que a altas horas de la noche (2,31/1000). Incluso tras ajustar los datos a la idoneidad del cuidado prenatal, las complicaciones del embarazo, el género y el peso al nacer, la tasa de mortalidad fue un 12% y un 16% superior en los que nacieron durante la noche, temprano y tarde, respectivamente.
