Asthma prevalence reached its
highest level ever in 2010 -- 8.4% of the population, up from 7.3% in 2001, according
to the CDC.
That translates into 18.7
million adults and 7 million children who had been diagnosed with asthma and
still had the condition in 2010, the agency said in a report called Asthma's
Impact on the Nation.
In 2009, asthma accounted for
3,388 deaths, 479,300 hospital admissions, 1.9 million emergency department
visits, and 8.9 million visits to doctors' offices.
On the other hand, the agency
reported, deaths from the disease have been declining from 2001 through 2009,
as have visits for asthma to physician offices and hospital outpatient
departments.
The death rate per 1,000
people with asthma was 0.14 in 2009, down from 0.21 in 2001, while the rate of
primary care encounters was 47.8 per 100 asthma patients in 2009, down from
61.9 in 2001.
Hospital admissions and
emergency room visits have been stable, the agency reported. The 2009 rates per
100 asthma patients were 8.4 and 2.0, respectively.
Asthma costs the U.S. $56
billion a year, with the average yearly cost of care for a child with asthma
reaching $1,039 in 2009, the CDC reported.
