Rhode Island Numbers

  • Since 2010, the percentage of Rhode Island adults that have ever been diagnosed with asthma is above the national average.

  • The percentage of Rhode Island children under age 18 that have ever been diagnosed with asthma is above the national average.
  • * Years 2011 and 2012 are omitted due to small numbers policy. Lifetime prevalence for U.S. children was 13.6% in 2011 and 13.7% in 2012.
  • Significant disparities exist in asthma rates. In the U.S., current asthma prevalence is higher among adults and children in households with family incomes below 100% of the federal poverty level (FPL) than adults and children in households with family incomes at or above the federal poverty level. For adults and children with asthma who live in poverty, exacerbation of asthma symptoms is frequent, leading to increased medication need, increased outpatient hospital visits and hospital admissions.
  • Since 2010, the percentage of Rhode Island adults with current asthma is above the national average.

  • The percentage of Rhode Island children under age 18 with current asthma was above the national average between 2010 and 2017, but not in 2018.
  • * Years 2011 and 2.012 are omitted due to small numbers policy. Current asthma prevalence for U.S. children was 8.7% in 2011 and 8.9% in 2012.
