The role of medical problems and behavioral risks in explaining patterns of prenatal care use among high-risk women.

OBJECTIVE

To examine the associations between maternal medical conditions and behavioral risks and the patterns of prenatal care use among high-risk women.

DATA SOURCE/STUDY DESIGN: Data on over 25,000 high-risk deliveries to African American and white women using multinomial logistic regression to predict the odds of adequate-plus care relative to three other categories of care.

DATA COLLECTION/EXTRACTION METHODS: Data were extracted from records maintained by the University of Florida/Shands Hospital maternity clinic on all deliveries between 1987 and 1994; records for white and for African American women were subset to examine racial differences in medical conditions, health behaviors, and patterns of prenatal care use.

PRINCIPAL FINDINGS

Net of sociodemographic and fertility-related characteristics, African American and white women with late antepartum conditions and hypertension problems had significantly higher odds of receiving adequate-plus care, as well as no care or inadequate care, relative to adequate care. White women with gynecological disease and medical/surgical problems were significantly less likely to receive no care or inadequate care, as were African American women with gynecological disease.

CONCLUSIONS

Maternal medical conditions explain much but not all of the adequate-plus prenatal care use. More than 13 percent of African American women and 20 percent of white women with no reported medical problems or behavioral risks used adequate-plus care. Additional research is needed to understand this excess use and its possibilities in mediating birth outcomes.
