Rates of childhood asthma appear to have plateaued, except among the poor and kids aged 10 to 17, according to a CDC study published in the journal Pediatrics.
Researchers found that childhood asthma rates increased from 2001 to 2009 — a trend that began in 1982. The rate peaked in 2009 at close to 10%, then leveled off before dropping to slightly more than 8% in 2013.
