Cesarean childbirth in Puerto Rico: the facts

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Epidemiology

Background:

• Cesarean delivery rates in Puerto Rico have historically been high.
• Data collection on delivery type improved with live birth certificate inclusion in 1989.
• Previous surveys indicated a cesarean rate of 27% for 1980-82.

Purpose of the Study:

• To analyze trends and contributing factors of cesarean delivery rates in Puerto Rico.
• To identify demographic and socioeconomic correlates of high cesarean rates.
• To compare cesarean rates between public and private healthcare institutions.

Main Methods:

• Analysis of island-wide survey data and live birth certificate information from 1980-1994.
• Examination of cesarean rates across different maternal demographics and socioeconomic statuses.
• Correlation analysis to determine key factors influencing cesarean delivery incidence.

Main Results:

• Cesarean delivery incidence reached 31% by 1994, potentially the world's highest rate.
• High rates of repeat cesareans and low rates of vaginal birth after cesarean (VBAC) contributed significantly.
• Adolescents, unwed mothers, lower socioeconomic status individuals, and those with adequate prenatal care exhibited higher cesarean rates.
• Private hospitals showed more than double the cesarean rate of public institutions, with hospital type being a primary correlate.

Conclusions:

• Cesarean delivery rates in Puerto Rico stabilized by the mid-1990s after a period of increase.
• Maternal risk factors and socioeconomic status were associated with higher cesarean rates.
• Healthcare setting, particularly private hospitals, played a crucial role in cesarean delivery prevalence.
