The average weight for a newborn baby in the United States is about seven pounds.1  Approximately one in 12 U.S. babies, 
however, is born with low birthweight, classified as weighing less than five pounds, eight ounces at birth.2  The complications 
associated with low birthweight are numerous and can be severe.  According to the Centers for Disease Control, complications 
related to low birthweight are a leading cause of infant mortality in the United States.3  Low birthweight also puts newborn 
babies at increased risk for a variety of acute health complications after birth, including respiratory distress syndrome and heart 
problems.  Very low birthweight babies (those born weighing less than three pounds, four ounces) may suffer from long-term 
neurological and developmental disabilities.4  
 
The two primary reasons babies are born with low birthweight are premature birth (defined as a birth taking place before 37 full weeks of pregnancy) or a fetal growth restriction – a problem that occurs when a baby does not grow in the womb at a normal rate.5,6  A number of risk factors increase the likelihood that 
a  woman  will  give  birth  to  a  low  birthweight  baby,  including  smoking,  drinking or  using  illicit  drugs  during  pregnancy,  inadequate  maternal  weight  gain  during 
pregnancy or chronic maternal health problems such as high blood pressure or 
diabetes.7  Additionally, women giving birth to multiples are more likely to have a 
low birthweight baby than women with single-baby births.  Research shows that 
more than half of multiple birth babies are born with low birthweight, compared 
to six percent of single birth babies.8 
Research has uncovered a number of disparities in the prevalence of low-weight births among women from different racial, 
socioeconomic and educational backgrounds.  The low-weight birth rate among black women is particularly troubling, for a variety 
of reasons that researchers have yet to comprehend.  In 2009, the rate of low-weight births for black women in the U.S. was 
nearly twice as high as the rate for non-Hispanic white women.9  Low-income women, women under the age of 17 and women 
lacking education also face an increased risk of giving birth to a low birthweight baby.10  
Nationally, low birthweight babies represented 8.2 percent of all live births in 2008.11  In the same year, low birthweight babies 
represented 8.9 percent of all live births in Colorado, giving the state the 12th highest rate of low-weight births in the country.12   
Consistent  with  the  national  trend,  the  percentage  of  low  birthweight  babies  among  black  women  in  Colorado  is 
disproportionately high, with nearly 15 percent of all live births in 2008 resulting in low birthweight babies.
