low birth weight
Why this is important: Low birth weight infants are at an increased risk of dying within the first year of life, experiencing delayed motor and social development, and having a learning disability. The risk of these outcomes increases as birth weight decreases, with very low birth weight infants (less than 1500 grams, or 3.3 pounds) having the greatest risk.
Definition: Percent of singleton births with a birth weight less than 2500 grams (5.5 pounds).
