Low birthweight (less than 2,500 grams) is the single most important factor affecting neonatal mortality and a significant determinant of postneonatal mortality. Low birthweight infants who survive are at increased risk for health problems ranging from neurodevelopmental disabilities to respiratory disorders.

The Healthy People 2010 objective for low birthweight established the target prevalence of 5 percent. In 2001, the U.S. prevalence of low birthweight (National Vital Statistics Reports) for all race/ethnicity groups was 7.7%, above the Healthy People 2010 target of 5% and therefore, considered to be a public health problem. To determine if low birthweight is a health problem within the state PNSS population, we will compare the percent of low birthweight infants from a state WIC program to the Healthy People 2010 target of 5 percent and the U.S. prevalence of low birthweight of 7.7%.


Percent of Low Birthweight Infants

The PNSS Table 8C (state level), Comparison of Infant Health Indicators, provides the prevalence of low birthweight defined as all infants less than 2500 grams that includes both very low birthweight and low birthweight infants.


Sample: PNSS Table 8C, Comparison of Health Indicators

table showing prevalence of birthweight indicators by state and nation

1 The prevalence of low birthweight infants in the state (7.7%) is slightly lower than the prevalence of low birthweight infants in the national PNSS (7.9%), however, it is the same as the U.S. prevalence (7.7%).


What: Is low birthweight a health problem?

The prevalence of low birthweight infants was 7.7% compared to the Healthy People 2010 target prevalence of 5 percent so it is considered a health problem.
