Health Indicator Report of Very Low Birth Weight Among Singleton Births

Low birth weight (LBW) increases the risk for infant morbidity and mortality. LBW infants are at greater risk of dying in the first month of life. LBW infants may require intensive care at birth and are at higher risk of developmental disabilities and chronic illnesses throughout life. They are more likely to require special education services. Health care costs and length of hospital stay are higher for LBW infants.

How Are We Doing?

In New Jersey, the average birth weight among singletons is 3,298 grams or 7 lbs, 4 oz. The percentage of singleton infants with very low birth weight (VLBW) has remained near 1.1% for at least a decade. The rate among Black mothers is more than double the rates among other racial/ethnic groups. Singleton VLBW rates are lowest among mothers ages 25-34 years. VLBW rates among singletons for New Jersey's counties range from 0.6% to 1.6%.

How Do We Compare With the U.S.?

The singleton very low birth weight rate among New Jersey residents is the same as that of the nation as a whole.
