Low-income women and their infants are at higher risk for problems related to pregnancy and delivery, including low birth weight. Low birth weight infants have an increased risk of death and permanent disability.  The care of low birth weight infants involves major costs to society.

The Comprehensive Perinatal Services Program (CPSP) provides a wide range of services to Medi-Cal-eligible women who receive comprehensive services, including prenatal care, health education, nutrition services, and psychosocial support for up to 60 days after delivery. Comprehensive services were shown to reduce the low birthweight rate by one-third and to save approximately $2 in short-term Neonatal Intensive Care Unit (NICU) costs for every $1 spent.
