Adequacy of Prenatal Care Summary

Adequacy of Prenatal Care is a measure of both access to and frequency of prenatal care based on the Adequacy of Prenatal Care Utilization (APNCU) Index developed by Kotelchuck. This index considers two aspects of prenatal care: the month it was initiated and the number of visits occurring after initiation.  The 1990 through 2004 Editions of the report defined Adequacy of Prenatal Care using the Kessner Index, a measure highly correlated to Kotelchuck; however, it does not consider both initiation and frequency of visits.

Adequacy of prenatal care is not adjusted for age or race.

Table 32 displays the 2007 ranks, based on 2004 data (National Center for Health Statistics. Adequacy of Care by State, United States, Hyattsville, Md.).  Not all prenatal care numbers are comparable since the data is collected from two different forms of birth certificates.  The states marked with asterisks have begun using the 2003 revision to the birth certificate and can only be compared to other states with an asterisk.  All other states use the 1988 revision and are directly comparable.  The states using the 2003 revision were assigned scores and ranks based upon prior year data to avoid a lowering of their scores due to the improved data collection method.

Access to adequate prenatal care ranges from more than 85 percent of pregnant women in New Hampshire, Maine and Vermont to less than 60 percent in New Mexico. 

The data has not changed since the 2006 Edition.
