Introduction

|
According to the Healthy People 2010 Objectives,
|
|
"Short gestation and LBW [Low Birth Weight] are among the leading causes of neonatal death, accounting for 20 percent of neonatal
deaths. In 1998, [U.S. wide] a total of 11.6 percent of births were preterm, and 7.6 percent were LBW. [Ventura, S.J.; Martin, J.A.;
Curtin, S.C.; et al. Births: Final data for 1997. National Vital Statistics Report 48(3), 2000.] Included in these
statistics were VLBW [Very Low Birth Weight] infants weighing less than 1,500 grams (3.3 pounds).

|
LBW is associated with long-term disabilities, such as cerebral palsy, autism, mental retardation, vision and hearing impairments, and
other developmental disabilities. [...] Despite the low proportion of pregnancies resulting in LBW babies, expenditures for the care of
LBW infants total more than half of the costs incurred for all newborns. In 1988, the cost of a normal, healthy delivery averaged
$1,900, whereas hospital costs for LBW infants averaged $6,200. [Lewit, E.M.; Baker, L.S.; Hope, C.; et al. The direct cost of low birth
weight. Future Child 5(1):35-56, 1995.]"

The California County Profile Reports include information on low birth weight and very low birth weight births.

Definitions
|
|
A baby is defined as having a low birth weight if its weight is less than 2,500 grams at delivery. A baby with unknown birthweight is not considered for this analysis.
|
|
A baby is defined as having very low birth weight if its weight is less than 1,500 grams at delivery. Note that very low birth
weight births are by definition also low birth weight births and counted in both birth weight measures. A baby with unknown birthweight is not considered for this analysis.
