About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Vital Statistics System-Natality (NVSS-N); Centers for Disease Control and Prevention, National Center for Health Statistics (CDC/NCHS)
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
70.5 (2007)
Target-Setting Method: 
10 percent improvement

Number of births to females receiving adequate prenatal care by the Adequacy of Prenatal Care Utilization Index (APNCU) in states that use the 2003 standard certificate of birth


Number of live births in states that use the 2003 standard certificate of birth

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Data Collection Frequency: 
Methodology Notes: 

    The Adequacy of Prenatal Care Utilization Index (APNCU) is a measure of prenatal care utilization that combines the month of pregnancy prenatal care begun with the number of prenatal visits. Rates can be classified as “intensive use,” “adequate,” “intermediate,” or “less than adequate.” For this measure, adequate prenatal care is defined as a score of either “adequate” or “intensive use.” A discussion of the APNCU has been published.

Caveats and Limitations: 
Estimates were calculated with data supplied by the states that had adopted the 2003 version of the U.S. State Certificate of Live Birth. Trends over time cannot be evaluated until such time as all states provide data in the same format.
Trend Issues: 
Estimates for 2007 are based on 22 states (representing 53 percent of all U.S. births), excluding AL, AK, AZ, AR, CT, GA, HI, IL, LA, ME, MD, MA, MI, MN, MS, MO, MT, NV, NJ, NM, NC, OK, OR, RI, UT, VA, WV, WI, DC, and New York City.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 16-06b in that for objective 16-06b, prenatal care adequacy was based on the month of first prenatal visit and number of visits as entered on the 1989 edition of the birth certificate. For this objective, prenatal care adequacy is calculated from the date of LMP, date of the first prenatal visit, and number of visits, as entered on the 2003 edition of the birth certificate.
