The Scottish perinatal mortality survey

Area of Science:

• Perinatal Medicine
• Public Health
• Epidemiology

Background:

• Perinatal mortality remains a significant public health concern.
• Understanding specific causes is crucial for developing targeted interventions.
• Previous studies have identified various risk factors, but comprehensive analysis is needed.

Purpose of the Study:

• To investigate the causes of perinatal deaths in single births in Scotland in 1977.
• To identify the leading contributors to perinatal mortality.
• To inform strategies for reducing infant mortality rates.

Main Methods:

• Case-record analysis of 1012 single perinatal deaths in Scotland, 1977.
• Classification of causes of death using an extended Aberdeen classification.
• Detailed examination of fetal abnormalities and infant birth weights.

Main Results:

• Fetal abnormality accounted for 265 deaths, with central nervous system malformations in 140 cases.
• Low birth weight in normally formed infants (mothers without complications) was the largest cause (302 cases), with 34% exhibiting growth retardation.
• Rhesus incompatibility and maternal diabetes were minor contributors to perinatal loss.

Conclusions:

• Fetal abnormality and low birth weight are key drivers of perinatal mortality.
• The findings underscore the need for continued monitoring and potential interventions for growth-retarded infants.
• A modified study is ongoing to assess the feasibility of regional audits for monitoring perinatal mortality trends.
