Cesarean section delivery rates: United States, 1981

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Epidemiology

Background:

• The cesarean section delivery rate in the United States has shown a notable increase over time.
• Understanding demographic and hospital-related factors influencing cesarean rates is crucial for public health initiatives.

Purpose of the Study:

• To analyze trends in cesarean section delivery rates in the United States.
• To identify demographic and hospital characteristics associated with variations in cesarean section rates.

Main Methods:

• Retrospective analysis of cesarean section delivery data.
• Statistical examination of rates based on geographical region, hospital size and ownership, payment source, and maternal age.

Main Results:

• Cesarean section rates rose from 4.5% in 1965 to 17.9% in 1981.
• Higher rates were associated with the Northeast region, large hospitals (≥500 beds), proprietary hospitals, Blue Cross insurance, and mothers aged 35+.
• Lower rates were observed in the North Central region, small hospitals (<100 beds), government hospitals, self-pay patients, and mothers under 20.

Conclusions:

• Significant variations in cesarean section delivery rates exist based on multiple factors.
• These findings highlight the need for further investigation into the drivers of cesarean section trends and disparities.
