Healthy People 2010 has identified physical activity as a leading health indicator for the United States. If you would like to track how your state or the whole country is doing in terms of healthy lifestyle behaviors, including physical activity, visit the Centers for Disease Control and Prevention Web site. At the CDC site you can get results from the national Behavior Risk Factor Surveillance System (BRFSS). This national survey monitors the health behaviors of our nation every year. The BRFSS is the assessment used to determine whether the nation is meeting the Healthy People 2010 objectives.
