Summary:
High levels of dust mite allergens were found in bedding in 23 percent, or nearly a quarter, of homes sampled in the First National Survey of Lead and Allergies in Housing. In addition, cockroach allergen was detectable in bedding of over 6% of homes.

High levels of dust mite allergens were found in bedding in 23 percent, or nearly a quarter, of homes sampled in the First National Survey of Lead and Allergies in Housing. In addition, cockroach allergen was detectable in bedding of over 6% of homes. The national survey was conducted from July 1998 to August 1999 under the sponsorship of the U.S. Department of Housing and Urban Development and the National Institute of Environmental Health Sciences.

The survey results are being presented in a scientific poster session at the 97th International Conference of the American Thoracic Society in San Francisco today, and highlighted at a press briefing sponsored by the American Thoracic Society at 11 a.m. in Room 114 at the Moscone Convention Center.

Sampling was done in 831 homes occupied by 2456 individuals in 75 different locations across of United States. In the survey, researchers collected vacuumed dust samples, environmental and demographic data, and health information from surveyed homes and their inhabitants.

From their data, the researchers estimate that dust mite allergens at levels previously associated with asthma and allergy are present in approximately 23.2 million U.S. homes. Dust mites are very minute arachnids (related to spiders) that live primarily on flakes of human skin. Dust mite allergens are proteins which come from the digestive tract of mites and are found at high levels in mite feces. Since the mites are too small to be visible to the naked eye, they escape people's notice, but they are present to some degree in nearly all human habitations.

The researchers found that a number of factors were significantly associated with increased risk for high dust mite allergen levels in the bed, including:

* Single family homes

* Low income households

* High bedroom humidity

* Presence of a musty or mildew odor in the bedroom

* Location in non-western parts of the U.S.

* Older homes (built before 1978)

* Non-Hispanic ethnicity of inhabitants.

The researchers also estimate that cockroach allergens are present in approximately 6 million U.S. homes. The major factors associated with increased risk for high bed cockroach allergen levels were:

* Low income households

* Presence of food debris

* Presence of a musty or mildew odor in the home

* Non-white race of inhabitants.

Lead author on the study Darryl C. Zeldin, M.D. said, "This study identifies important factors that are associated with increased exposure to indoor allergens. This information can be used to identify homes and individuals that are at greatest risk of exposure so that researchers can better target their prevention and intervention efforts." Though the research wasn't specifically focused on reducing indoor allergens, some steps might include frequent and rigorous cleaning of bedding, use of allergen barriers on mattresses and pillows, controlling moisture indoors with the use of dehumidifiers, moisture barriers and moisture proofing of foundations, and eliminating sources of food debris. The NIEHS Asthma Website (http://www.niehs.nih.gov/airborne/home.htm) has more information on how to reduce allergen levels in the home.

Authors on the studies with Dr. Zeldin were Drs. P.J. Vojta, NIEHS; W. Friedman and J. Zhou, OLHC/HUD; E. Schuett and R. Cohn, ASI/RTP; H. Burge and M. Muilenberg, Harvard University; and P.S. Thorne, University of Iowa.
