  • Description
    Births by Maternal Behaviors - 1-Year Data reports the annual number and percentage of births in certain categories by maternal behavior characteristics (smoking status during pregnancy and initiation of prenatal care).
  • Full Description
    This dataset provides select birth outcomes (birthweight, gestational age) for Connecticut resident births along with select behavioral characteristics of the mother (smoking status during pregnancy and initiation of prenatal care). Low birth weight is less than 2500 grams, or about 5.5 pounds. Very low birth weight is less than 1500 grams, or about 3.3 pounds. A birth is premature if it occurs before the gestational age of 37 completed weeks. Smoking status during pregnancy is self-reported by the mother at time of delivery. Initiation of prenatal care refers to the trimester of pregnancy the mother was in when she was first counseled by a provider for that pregnancy. Late prenatal care is the initiation of prenatal care after the first trimester of pregnancy. Department of Public Health collects and publishes annual vital statistics reports ( and carries annual data, 3-year and 5-year averages. More dimensions can be found in the raw data such as birth pluralities. Alcohol use is no longer displayed on as it is rarely reported and not a reliable indicator.
