Patterns of prenatal care initiation in Georgia, 1980-1992

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Epidemiology

Background:

• Prenatal care initiation timing is crucial for maternal and infant health outcomes.
• Understanding factors influencing prenatal care timing can inform public health interventions.
• Previous pregnancy characteristics may influence healthcare-seeking behaviors in subsequent pregnancies.

Purpose of the Study:

• To investigate the association between first pregnancy characteristics and the timing of initiating prenatal care in a second pregnancy.
• To identify predictors of early versus delayed prenatal care in subsequent pregnancies.

Main Methods:

• Analysis of Georgia birth certificate data (1980-1992) for 177,041 women with singleton live births in their first and second pregnancies.
• Logistic regression models calculated adjusted relative risks (RRs) for early prenatal care in the second pregnancy.
• Models controlled for demographic factors and stratified analyses by race.

Main Results:

• Women who received first-trimester prenatal care in their first pregnancy were more likely to do so in their second pregnancy (RR=1.25-1.63).
• Experiencing adverse infant outcomes (very low birth weight, infant death) in the first pregnancy increased the likelihood of initiating first-trimester care in the second pregnancy (RR=1.06-1.31).
• Women who delayed prenatal care in their first pregnancy were likely to continue delaying it in their second pregnancy.

Conclusions:

• Certain adverse infant outcomes and early care initiation in a first pregnancy are associated with earlier prenatal care in a subsequent pregnancy.
• Women who delayed prenatal care in their first pregnancy often continue this pattern in their next pregnancy.
• Targeted interventions may be needed for women with a history of delayed prenatal care to improve initiation timing.
