Cockroach Allergens and Asthma

Among children, cockroach allergens can cause wheezing and coughing. These allergies can also lead to skin rashes and a whistling sound while breathing. Asthma is a common disease in children and can be triggered by a variety of factors, including cockroach allergens. According to the National Pest Management Association (NPMA), cockroach allergens are present in 63 percent of homes in the U.S., and they can cause asthma and allergies by activating the immune system.

Children with cockroach allergies can even be hospitalized for asthma more often than other kids. As many as 25% of city dwellers are allergic to cockroach allergens, and some researchers believe that increased exposure to cockroach allergens may be a factor in the increase in asthma cases. Cockroach allergens are thought to trigger allergic reactions primarily due to proteins found in their feces, bodies, and saliva.

In a meta-analysis study of all studies conducted from 2000 to 2013, researchers found a link between cockroach allergens and asthma. In addition, children with cockroach sensitization have higher asthma morbidity and mortality. In fact, children with asthma diagnosed after living in a home with a high cockroach allergen content had a three-fold higher risk for asthma.

The National Pest Management Association (NPMA) warns that cockroach allergens can trigger allergies, especially in young children. These allergens can be present in cockroach droppings, saliva, and decomposing bodies. All of these materials can cause severe allergic reactions and even cause existing asthma.
