[Maternal history impact in neonatal mortality]

Area of Science:

• Perinatal Medicine
• Neonatal Health
• Public Health

Background:

• Perinatal assessments identify maternal psychosocial, medical, and obstetrical factors influencing neonatal mortality.
• Understanding these risk factors is essential for targeted interventions.

Purpose of the Study:

• To determine the prevalence of maternal risk factors.
• To evaluate the impact of these factors on neonatal mortality.

Main Methods:

• A cohort study of 25,365 live newborns (2000-2004).
• Maternal history, birth data, and neonatal outcomes were collected.
• Statistical analysis included prevalence, odds ratios, and attributable fractions.

Main Results:

• Maternal age ≥30, <7 prenatal consultations, eclampsia, type 2 diabetes, and urinary tract infections were associated with increased mortality.
• Positive HIV serology, prolonged membrane rupture (>48h), polyhydramnios, and placental abruption showed significant associations with higher neonatal mortality.

Conclusions:

• Delivery-related risk factors have a greater impact on neonatal mortality than pre-pregnancy or pregnancy factors.
• Focusing on intrapartum events is critical for reducing newborn deaths.
