Why do we measure prenatal care? 

Starting prenatal care in the first trimester helps prevent complications throughout pregnancy, is linked to a longer gestation period, and reduces the likelihood that a child will be born at a low birthweight.(1-3) Up to half of pregnancy-related deaths could be prevented with recommended prenatal care services that range from screening for birth defects to advice on pregnancy.(4,5)

Unfortunately, those who are at the highest risk of experiencing problems related to childbirth are often the least likely to receive adequate prenatal care.(6) These women are often younger, less educated, and/or are unintentionally pregnant.(2) Black women are less likely to receive adequate prenatal care compared to non-Black women due to systemic factors.(4)

How do we measure prenatal care?

 This metric includes births for which prenatal care began in the first trimester of pregnancy. 

Strengths of Metric

Limitations of Metric

Prenatal care helps determine if pregnant people are able to access care early during their pregnancies. Early initiation of care allows clinicians to identify risk factors for poor birth outcomes and facilitates intervention as needed. 

The prenatal care metric does not take into consideration different cultural perceptions and expectations of pregnancy and prenatal care.(7) 

The prenatal care metric evaluates when care was initiated, not the quality or frequency of care during pregnancy.

Calculation

Prenatal care is calculated by the following formula:

Prenatal Care Formula

Prenatal care represents one component of the Kotelchuck Index.(8) This metric was calculated by aggregating estimates from smaller geographies to the congressional district level. For more information on the calculation, please refer to the Congressional District Health Dashboard Technical Document.   

Data Source

Estimates for this metric are from Natality Data from the National Vital Statistics System of the National Center for Health Statistics.

Years of Collection

For total population, calculated by the Dashboard Team using data from 2020, 1 year estimate

For all specific demogroups, including racial/ethnic subgroups and gender subgroups, calculated by the Dashboard Team using data from 2020, 3 year estimate
