Determinants of the neonatal mortality

Area of Science:

• Neonatalogy
• Pediatric Mortality Studies
• Public Health

Background:

• Neonatal mortality rates historically present challenges in newborn care.
• A notable decline in neonatal mortality was observed at the medical center.
• This prompted an investigation into the contributing factors.

Purpose of the Study:

• To analyze viral statistics and identify factors influencing neonatal mortality.
• To correlate neonatal mortality trends with infant birth weights.
• To understand the drivers behind the recent sharp decline in neonatal deaths.

Main Methods:

• Retrospective analysis of neonatal mortality data from 1966 to 1973.
• Examination of the incidence of infants with birth weights of 1,500 grams or less.
• Statistical correlation between birth weight distribution and mortality rates.

Main Results:

• Mean neonatal mortality decreased from 15.4 to 11.0 per 1,000 live births between the periods 1966-1973 and 1972-1973.
• A direct relationship was found between annual neonatal mortalities and the incidence of infants weighing 1,500 gm or less.
• Reduced proportion of low birth weight infants accounted for 75% of the mortality improvement; decreased mortality in this group accounted for the remaining 25%.

Conclusions:

• The reduction in neonatal mortality is strongly linked to a decrease in the proportion of infants born with very low birth weights.
• Improved survival rates among infants weighing 1,500 gm or less also contributed significantly to the decline.
• These findings highlight the critical impact of birth weight management on neonatal outcomes.
