NHANES National Youth Fitness Survey
The NHANES National Youth Fitness Survey
The NHANES National Youth Fitness Survey (NNYFS) was conducted in 2012 to collect data on physical activity and fitness levels in order to provide an evaluation of the health and fitness of children in the U.S. ages 3 to 15. The NNYFS collected data on physical activity and fitness levels of our youth through interviews and fitness tests.
In October 2008, the federal government issued its first-ever Physical Activity Guidelines for Americans to provide science-based guidance on the types and amounts of physical activity that provide substantial health benefits for Americans. Guidelines for children and teens ask for 60 minutes or more of aerobic, muscle-strengthening, or physical activity daily.
While the number of children in the U.S. who meet the Physical Activity Guidelines is unknown, the percentage of children who are physically active in the U.S. is declining. The inclusion of fitness tests, in the NNYFS for ages 3–15, provides additional information with which to evaluate the health of this age group.
The survey was conducted in 2012 by the Division of Health and Nutrition Examination Surveys, National Center for Health Statistics, part of the Centers for Disease Control and Prevention.
