Investigators at the Robert Wood Johnson Medical School and Boston University analyzed data from two national surveys to examine teenage pregnancy rates from 1991 to 2001 in African-American and white teenagers and identify factors that influence these rates.
For a three-year period starting in August 2000, the researchers analyzed data from the Centers for Disease Control and Prevention's Youth Risk Behavior Survey and the National Institutes of Health-funded National Surveys of Adolescent Males.
They identified factors that affect teen pregnancy (e.g., start of sexual activity and consistent use of birth control) and sought to determine the importance of each factor for African-American and white teenagers.
There was a significant decline in pregnancy rates among African-American teenagers.
There was a significant decrease in sexual activity among African-American teenagers, with the largest reduction occurring between 1999 and 2001.
There was a significant increase in the prevalence and frequency of condom use.
