How Renting Instead of Owning Can Hurt Your Asthma
Renters Less Likely Than Homeowners to Follow Recommendations
Aug. 3, 2012 -- The real estate crash may be having a surprising effect on the health of some Americans with asthma.
A survey of people with allergic asthma found that renters are less likely than homeowners to make changes to minimize exposures to the allergens that trigger their breathing problems.
Allergens such as dust mites, pet dander, pollen, and mold are common asthma triggers. More than half of people with asthma in the U.S. are allergic to something in their environment.
Taking steps to minimize exposure to these environmental triggers in the home is an important component of asthma control, but renters took these steps less often than homeowners.
The study, published in the August issue of Annals of Allergy, Asthma & Immunology, found that while 91% of homeowners made recommended changes, just 63% of renters did.
Clean Air in Home Reduces Asthma
Home ownership fell to its lowest level in more than a decade earlier this year, and the bursting of the housing bubble continues to deflate home prices in many parts of the U.S.
Researcher Michael Schatz, MD, of the Kaiser Permanente Medical Center in San Diego, Calif., says although some recommendations like removing wall-to-wall carpeting may be impractical for renters, many others, such as washing bedding regularly, are not.
The researchers found that renters and homeowners both were more likely to make recommended changes within the home when they were made aware of the changes that would help them most.
"When people knew what they were allergic to and how to reduce their exposure to the specific allergen, most people took steps to minimize their exposure," he tells WebMD.
Simple Steps Have Big Impact
For example, the study found that most people were willing to wash bedding in hot water to reduce dust mites, clean visible mold, and reduce home humidity to below 60% with an air conditioner or dehumidifier.
Allergist James Sublett, MD, says these and other no-cost or low-cost steps can have a big impact on allergic asthma symptoms.
Sublett is chairman of the American College of Allergy, Asthma and Immunology Indoor Environment Committee.
