The incidence, risk factors, and mortality of preterm neonates: a prospective study from Jordan (2012-2013)

Objectives: to explore the incidence of preterm delivery, maternal risk factors for having a premature neonate and preterm neonates' mortality in Jordan.
Material and Methods: a cross-sectional population based design was applied. Socio-demographic, perinatal, and delivery risk factors and survival information were gathered in pre- and post-hospital discharge interviews with 21,075 women who gave birth to live neonates at ≥20 weeks of gestation in 18 hospitals in Jordan. Women were interviewed between 2012 and 2013. The sample was limited to singleton women who gave birth to live neonates. Women who gave birth to stillborn babies were excluded.
Results: Preterm delivery incidence was 5.8%, of which 85% were in 32-36 gestational weeks. Male sex, primigravidity, hypertension, preeclampsia, and diabetes were significantly associated with an increased risk of preterm delivery. Women aged 20-35 years had the lowest risk of preterm delivery. Mother’s weight <50 kg, hospitalization at 24-34 gestational weeks, lack of antenatal care visits or <8 visits during pregnancy, a history of preterm delivery, and a history of stillbirth/neonatal death were associated with increased risks of preterm delivery. The neonatal mortality rate was 4/1000 live births among full-term and 123/1000 live births among preterm babies. Prematurity, congenital anomalies, and maternal diseases were the causes of 84% of preterm neonatal deaths.
Conclusion: The mortality rate was considerably higher among preterm neonates than among term neonates; discrepancies between Jordan and other countries existed. Systematic prenatal risk assessment and quality postnatal health care improvements are required to improve the survival rates of preterm neonates.
