For decades, childhood asthma was linked to living in urban areas. This is not the case anymore, says researchers from Johns Hopkins University School of Medicine. Race, ethnicity and poverty are actually more closely associated with the lung disease than location in urban neighborhoods. Looking at data from 23,065 children across the United States, they found that self-reported asthma attacks were equally found between inner city areas and all others areas. Interestingly, researchers found that “black race, Puerto Rican ethnicity and poverty rather than residence in an urban area per se are the major risk factors for prevalent asthma.” For African-Americans and Puerto Ricans, higher risk of asthma may be genetic, says Corrine Keet, assistant professor of pediatrics. For the poor, it may be stresses such as exposure to mouse and cockroach allergens, cigarette smoke, a higher rate of pre-term births and more maternal stress, she said. It is unclear whether inner-city children who have asthma may suffer more severe symptoms as a result of allergens there. Another study is currently being conducted to determine this. How often do you counsel patients with asthma symptoms? Are you in agreement with the latest findings?
