Missoula Measures - Birth Weight
Source: Vital Statistics, MDPHHS.
Low Birth Weight babies (LBW - less than 5 1/2 pounds) are more likely to have a host of physical and mental health issues. While their early lives often require much specialized health care intervention, they are also at much higher risk for a host of developmental and physical problems through out their lives.
In the US, in 2012:
- 8% of births to all ages were low birth weight babies.
- 10% of babies born to 15-19 year olds were low birth weight.
- 13% of babies born to mothers younger than 15 were low birth

A 2011 Quality of Life research study "suggests that caring for a baby born with very low birth weight can have negative effects for maternal health, contributing to long-term or chronic stress for the mother." University of Wisconsin-Madison, Dr. W. Witt
