Perinatal mortality in Shanghai: 1986-1987

Area of Science:

• Obstetrics and Gynecology
• Neonatal Research
• Public Health

Background:

• Perinatal mortality remains a significant public health concern globally.
• Understanding regional risk factors and causes is crucial for targeted interventions.

Purpose of the Study:

• To examine the incidence and risk factors of perinatal mortality in Shanghai.
• To identify major causes of perinatal deaths.
• To compare Shanghai's rates with international data.

Main Methods:

• A multi-site study was conducted across 29 hospitals in Shanghai.
• Data from 1986-1987 were analyzed to determine mortality rates and associated factors.

Main Results:

• The overall perinatal mortality rate was 14.96 per 1000 births.
• Risk factors included male sex, low birthweight, preterm birth, higher parity, multiple pregnancy, and maternal age ≥35.
• Mortality rates peaked in winter and late spring.
• Major causes were asphyxia, cord complications, and congenital malformations.

Conclusions:

• Perinatal mortality in Shanghai is influenced by various maternal and infant factors.
• Seasonal variations and specific causes necessitate tailored preventive strategies.
• A shortage of advanced perinatal care technology, like neonatal intensive care units, presents a barrier to reducing mortality rates.
