Complete Health Indicator Report of Birth Outcomes: Growth Retardation at Birth: Percentage of Low Birthweight Live Term Singleton Births

Definition

Percentage of Low birthweight, term, singleton infants (LBW infants) is the number of live-born singleton infants born at term (at or above 37 completed weeks of gestation) with a birthweight of less than 2,500 grams (about 5 pounds, 8 ounces), per 100 live, term, singleton births.

Numerator

Number of live-born, singleton infants born at term (at or above 37 completed weeks of gestation) with a birthweight of less than 2,500 grams.

Denominator

Total number of live-born, singleton infants born at term.

Data Interpretation Issues

The live birth data are from items reported on the birth certificates. Data are collected on all births occurring in-state as well as births to NM residents that occur out-of-state.

Why Is This Important?

LBW affects about one in every 13 babies born each year in the U.S. Studies have shown that LBW is an important predictor of future morbidity and mortality. Compared to infants of normal weight, LBW infants may be at increased risk of perinatal morbidity, infections, and the longer-term consequences of impaired development, such as delayed motor and social development or learning disabilities. The percentage of LBW births among term singleton births is a measure of growth retardation at birth and perinatal health. It can be used to examine the indicator trends and patterns that occur over time and space. These trends may reflect the contributions of environmental exposures and other modifiable risk factors to LBW births.
