Asthma is a common chronic airway disorder characterized by periods of airflow obstruction known as asthma attacks (1). Symptom frequency can range from intermittent to fixed,and attack severity can vary from gentle to life threatening (1). Several studies have shown that among adults, obesity is associated with an increased risk of asthma diagnosis, or more frequent asthma-related health care use,and greater symptom or severity burden (2-6). In this report, current asthma prevalence is examined by weight status among U.
S. adults aged 20 and over.
