According to the Department of Health and Human Services, adequate prenatal care is associated with reduced maternal and infant morbidity and mortality, reduced risk for preterm delivery and low birthweight birth, and other improved pregnancy outcomes. Starting prenatal care in the first trimester increases opportunities for maternal education and addressing behavioral health issues, and is widely recommended by gynecologists, pediatricians, and various national health experts such as the American College of Obstetricians and Gynecologists.
Prenatal care data can generally be collected from the state department of public health with other birth records information. Divide the number of live births where the mother received prenatal care in the first trimester by the total number of live births in the zip code. The zip codes are based on the mother's residence at the time of delivery. Data should only be presented for zip codes with five or more live births.
As noted by the California Center for Health Statistics, "When examining data in ZIP codes with very small live birth numbers (n < 100), caution must be exercised because very small numbers may be unreliable and subject to significant variability from one year to the next. Additional information concerning the data source and limitations is discussed in Vital Statistics of California, 2003 http://www.dhs.ca.gov/hisp/chs/OHIR/reports/vitalstatisticsofcalifornia/vsofca2003.pdf."
Access to pre-natal care in the first trimester is one of multiple factors affecting access to appropriate maternal and child health care. Other factors such as health insurance coverage, transportation to and from the health facility, cultural competency or cultural humility of health care providers, hours of operation, length of reimbursement period, cultural and linguistic competency of administrative and intake staff, availability of child care, availability of prevention programs, and employer requirements are among many factors impeding reliable, continuous access to affordable, quality health care.
