Health Indicator Report of Prenatal Care in the First Trimester

Prenatal care is the health care a woman gets while she is pregnant. Health care providers recommend that women begin prenatal care in the first trimester of their pregnancy. Regular, recommended prenatal care reduces the risk of pregnancy-related complications for the mother and infant and increases a woman's chances of having healthy baby at full term.


U.S. value for 2008 represents only the 27 states using the 2003 standard birth certificate. New Mexico implemented the 2003 U.S. standard birth certificate in 2008. Data from 2008 and later are not comparable with earlier years. See "Data Interpretation Issues" in this indicator report for more information on data changes as a result of the new birth certificate implementation.

Data Interpretation Issues

The U.S. revised the birth certificate in 2003. Many of the new variable formats (such as that for prenatal care) were not compatible with the previous formats. In addition, not all states implemented the new birth certificate at the same time. New Mexico implemented a new electronic birth certificate registration system in 2007 and the new birth certificate in 2008. As states began using the new certificate, prenatal care rates dropped off, largely because of missing data. The changes to the birth certificate make comparisons across states and across years problematic.
