Causas de mortinatalidad en Chile entre 2002-2015
Resumen
Introducción: Un mortinato, es un evento del embarazo que supone un resultado negativo para padres, familias y personal de salud involucrado. La falta de recursos podría ser el principal obstáculo al acceso de atención prenatal, síntoma de inequidades en salud. El débil conocimiento de causas de mortinatalidad se asocia a la creencia de que son inevitables; sin embargo, muchos factores vinculantes son potencialmente modificables.
Objetivo: Describir las causas de mortinatalidad en Chile.
Material y métodos: Estudio transversal y analítico. El análisis se precisó desde las 22 semanas gestacionales, según criterio estándar de la Organización Mundial de la Salud. Las causas de mayor frecuencia se utilizaron para determinar asociación mediante test con nivel de significación estadística p<0,05.
Resultados: El mayor porcentaje de muertes fetales se registró a las 35 o más semanas (35,63%). Principales macro-causas de mortinatalidad fueron tipo: fetal (47,0%), placentaria (31,4%) y desconocida (10,89%). Principales causas específicas fueron: hipoxia intrauterina (24,4%), causa no especificada (10,87%), y anomalías morfológicas-funcionales placentarias (10,83%). Causa específica hipoxia intrauterina se asocia a edad gestacional, edad materna y nivel educacional materno (p<0,05).
Conclusiones: La salud prenatal es reflejo de atención obstétrica, calidad y progreso en atención sanitaria. Existen brechas en detección de causas y calidad de los registros, por lo que las causas desconocidas tiendan al alza en el tiempo. Es recomendable adicionar al registro de muertes fetales componentes temporal, biológico y social maternos.
Palabras claves: Mortinatalidad, muerte fetal, inequidades en salud, resultado del embarazo, causas de muerte, factores de riesgo.
