Low Birth Weight: Percentage of Live Births, 2017
Somerset7.6% 95% Confidence Interval(6.7% - 8.6%)Description of the Confidence IntervalThe confidence interval indicates the range of probable true values for the level of risk in the community.
A value of "NA" (Not Available) will appear if the confidence interval was not published with the NJSHAD indicator data for this measure.
Somerset Compared to State
Description of Gauge
Description of the GaugeThis graphic is based on the county data to the left. It compares the county value of this indicator to the state overall value.
The county value is considered statistically significantly different from the state value if the state value is outside the range of the county's 95% confidence interval. If the county's data or 95% confidence interval information is not available, a blank gauge image will be displayed with the message, "missing information."NOTE: The labels used on the gauge graphic are meant to describe the county's status in plain language. The placement of the gauge needle is based solely on the statistical difference between the county and state values. When selecting priority health issues to work on, a county should take into account additional factors such as how much improvement could be made, the U.S. value, the statistical stability of the county number, the severity of the health condition, and whether the difference is clinically significant.
- Excellent = The county's value on this indicator is BETTER than the state value, and the difference IS statistically significant.
- Watch = The county's value is BETTER than state value, but the difference IS NOT statistically significant.
- Improvement Needed = The county's value on this indicator is WORSE than the state value, but the difference IS NOT statistically significant.
- Reason for Concern = The county's value on this indicator is WORSE than the state value, and the difference IS statistically significant.
Why Is This Important?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?Birth weight is highly correlated with plurality and gestational age. While 2.3% of full term singletons are of low birth weight (LBW), nearly one-quarter of full term twins are born at a weight below 2,500 grams. Similarly, 1.0% of singletons are of very low birth weight (VLBW) compared to 9.1% of twins and over one-third of triplets. In New Jersey, the average birth weight is 3,258 grams or 7 lbs 3 oz. The overall LBW rate reached an all time high of 8.4% in 2011 but has since declined. The very low birth weight rate among New Jersey births had been around 1.5% since the 1990s before declining to 1.4% in 2015. LBW rates vary widely across the state and by several maternal and infant characteristics. Black mothers are more likely to deliver LBW (12.3%) and VLBW (2.9%) infants than are other racial/ethnic groups. The only exception is LBW among full term singletons where the rate among Asian mothers is the same as the rate among Black mothers (3.6%). The LBW rate among all births and VLBW among singletons is highest for the youngest (15-19 years) and the oldest (40-44) mothers. LBW among full term singletons decreases with increasing maternal age, while VLBW among all births is highest among older (40-44) mothers. Overall LBW rates for New Jersey's counties range from 6% in Morris and Sussex to 10% in Cumberland County.
What Is Being Done?The [http://www.nj.gov/health/fhs/ Division of Family Health Services] in the New Jersey Department of Health administers programs to enhance the health, safety and well-being of families and communities in New Jersey. Several programs are aimed at improving birth outcomes.

Measure Description for Low Birth Weight
Definition: Percent of live-born infants delivered with a birth weight of less than 2,500 grams (low birth weight) or less than 1,500 grams (very low birth weight) 2,500 grams is about 5 lbs, 8 oz and 1,500 grams is about 3 lbs, 5 oz.
Numerator: Number of live-born infants with a birth weight of less than 2,500 grams (LBW) or less than 1,500 grams (VLBW) born to resident mothers
Denominator: Number of live infants born to resident mothers
