How many children have arthritis?
A new CDC study estimates that 294,000 U.S. children under age 18 (or 1 in 250 children) have been diagnosed with arthritis or another rheumatologic condition. (Type data table and state table.) Prior estimates ranged from 80,000 to 290,000, depending on the definition of arthritis, age range and methods used to find cases. However, many of these prior estimates were based on extrapolations from small studies done in small geographic areas which could have led lead to chance variation in estimates. More info.
