title: Awareness and knowledge of the 2008 Physical Activity Guidelines for Americans.
abstract: BACKGROUND
  To estimate the proportion of U.S. adults aware and knowledgeable of the 2008 Physical Activity Guidelines for Americans.
  
  
  METHODS
  Analysis is based on a cross-sectional national sample of adults in the 2009 (n = 4281) HealthStyles survey. We estimated the prevalence of adults who reported awareness of government physical activity guidelines and who were knowledgeable of the currently recommended moderate-intensity physical activity guideline (ie, 150 minutes per week) from the 2008 Guidelines.
  
  
  RESULTS
  In 2009, the percent of adults who reported being aware of government physical activity (PA) guidelines was 36.1%. The percent of adults knowledgeable of the moderate-intensity physical activity guideline was less than 1% (0.56%).
  
  
  CONCLUSIONS
  Most U.S. adults lack sufficient awareness and knowledge of the 2008 Guidelines, putting them at risk for failure to meet them. The nation needs more effective communication strategies to translate and disseminate PA guidelines.
