Statistics related to asthma and
According to the latest available statistics from the National
Institute of Allergy and Infectious Diseases:
- From 1990 to 1994, the number of people
with self-reported asthma in the US increased from 10.4 million to
- Asthma was the first-listed diagnosis in
468,000 US hospital admissions in 1993.
- Asthma affected an estimated 4.8 million
US children (under age 18) in 1994.
- Asthmatic youngsters under age 15
underwent 159,000 hospitalizations in 1993, with an average length of
stay of 3.4 days.
- Asthma is 26 percent more prevalent in
African-American children than in Caucasian children.
- African-American children with asthma
generally experience more severe disability and have more frequent
hospitalizations than do Caucasian children.
- Among 5-24 year olds, the asthma death
rate nearly doubled from 1980 to 1993.
- In 1993, African-Americans in this age
group were 4 to 6 times more likely to die from asthma than
- Males were 1.5 times at greater risk
- Asthma treatment cost an estimated $6.2
billion in 1990, including direct and indirect expenditures:
- Forty-three percent of that total cost
was associated with emergency room use, hospitalization, and death.
- Loss of school days, alone, caused
decreased productivity that cost an estimated $1 billion.
- While there are no solid statistics,
estimates from a skin test survey suggest that allergies affect as
many as 40 to 50 million people in the US.
- Allergy testing was listed as the reason
for 1.4 million office visits to physicians in 1991.
- Pollen allergy (hay fever or allergic
rhinitis) affects nearly 9.3 percent of the people in the US, not
including those with asthma.
- Allergic rhinitis was the reason for 7.6
million office visits to physicians in 1992.
- Allergic dermatitis (itchy rash) is the
most common skin condition in children younger than 11 years of age.
- Urticaria (hives; raised areas of
reddened skin that become itchy) and angioedema (swelling of throat
tissues) together affect approximately 15 percent of the US population
- More than 1,000 systemic allergic
reactions to natural rubber latex, including 15 deaths, were reported
to the Food and Drug Administration from 1988 to 1992. Case follow-ups
showed that the reactions were caused by residual rubber tree proteins
in medical devices such as rubber gloves and catheters. Most (82
percent) allergic reactions to latex are caused by rubber additives.
- Chronic sinusitis, most often caused by
allergies, affects nearly 35 million people in the US.
- Allergic drug reactions, commonly caused
by antibiotics such as penicillin and cephalosporins, occur in 2 to 3
percent of hospitalized patients.
- Eight percent of children younger than 6
years experience food intolerances. Of this group, 2 to 4 percent
appear to have reproducible allergic reactions to food. In adults, an
estimated 1 to 2 percent are sensitive to foods or food additives.
- A severe allergic reaction known as
anaphylaxis occurs in 0.5 to 5 percent of the US population as a
result of insect stings. At least 40 deaths per year result from
insect sting anaphylaxis.
