What allergen is primarily associated with high asthma morbidity in inner-city populations?

Cockroach allergen is primarily associated with high asthma morbidity in inner-city populations due to several factors. Urban environments often have overcrowded living conditions, poor sanitation, and higher levels of humidity, all of which can contribute to increased cockroach prevalence. These insects thrive in such environments and leave behind droppings, body parts, and secretions that can trigger asthma symptoms in sensitive individuals.

Research has shown that exposure to cockroach allergens is a significant risk factor for developing asthma and exacerbating existing asthma conditions. In fact, children living in inner-city areas with high cockroach exposure typically experience more severe asthma symptoms, hospitalizations, and a greater need for asthma-related interventions.

While allergens like dust mites, pollen, and mold spores can also contribute to asthma morbidity, cockroach allergens are particularly problematic in urban settings due to the specific environmental conditions that favor their presence and the potent allergenic properties of their waste products.
