In 2014, 9.6% of U.S. babies were born preterm, which is costly. CenteringPregnancy aims to decrease the rate of preterm and low weight babies, increase breastfeeding rates, and improve pregnancy spacing.  

CenteringPregnancy prenatal care follows the recommended schedule of 10 prenatal visits, but each visit is 90 minutes to two hours long and includes group discussion with 8-12 women. Materials help moms and providers ensure that everything from nutrition, common discomforts, stress management, labor and delivery, breastfeeding, and infant care are covered in group.

We use a variety of data sources to tailor our analysis to the location and to make our estimates as accurate as possible. However, sometimes data is unavailable, either because it has not been collected, or because it is not shared publicly. We encourage government agencies and other organizations to share their de-identified data online and researchers to prioritize the following gaps in the data.

Data by race/ethnicity and income was unavailable for all outcomes. Therefore, an imputation procedure was implemented in order to determine baseline prevalence rates of each outcome by race/ethnicity and income category. The underlying assumption behind the imputation strategy is that the relative risk of the outcome between income groups was similar across race/ethnicity categories. 

In addition, data by income (as percent of FPL) was also difficult to obtain for a number of birth outcomes such as pre-term birth and NICU admissions. Information from studies and other analyses was utilized to supplement the data gaps as they relate to income.
