The National Asthma Survey (NAS) is a joint effort between the Centers for Disease Control and Prevention (CDC) and National Center for Health Statistics (NCHS) and is sponsored by the National Center for Environmental Health (NCEH). The National Asthma Survey examines the health, socioeconomic, environmental, and behavioral predictors of asthma control. This survey explores the content of care and health care experiences of people with asthma. Health indicators include, but are not limited to: asthma attacks, asthma education, missed school/work days due to asthma, and prescription use.
