  • Purpose: To determine trends and critical populations that have asthma
  • Key Information: The prevalence and healthcare usage of adults, children, and smokers with asthma.

Rhode Island Numbers

Prevalence Rates

Adults With Asthma

  • In 2009, just over 82,000 Rhode Island adults (ages 18+) reported having asthma.
  • Between 2006 and 2009, the percentage of adults with self-reported having asthma was stable (from 10% to 11%).
  • Asthma is more common among adult women (13%) than men (7%).

Children with Asthma

  • In 2009, about 25,000 Rhode Island children (people younger than 18) reported having been diagnosed with asthma (11%).
  • There has been little change in the percentage of children with asthma between 2005 and 2009 in the state or country.
  • In Rhode Island, asthma is more common in boys (ages 5-17) than in girls of the same age.

Data/Full Screen

Note: For each year of Behavioral Risk Factor Surveillance System (BRFSS) data, there are two asthma prevalence measures. Lifetime asthma is defined as answering yes to the question "Have you ever been told by a doctor, nurse or other health professional, that you have asthma?" Current asthma is defined as answering yes to that question and yes to "Do you still haveasthma?"
