Routine asthma screening in urban children found 8% undiagnosed, linked to poor housing.
Routine asthma screening during well-child visits in high-prevalence urban areas identified undiagnosed asthma in 8% of 650 children screened between 2021 and 2024, according to a study presented at the American Academy of Pediatrics meeting.
Over two-thirds of children without prior diagnoses had at least one risk factor, including nighttime coughing, breathing difficulties during exercise, or prior inhaler use, with about 24% of those with risk factors receiving a diagnosis.
Poor housing conditions—such as mold, pests, peeling paint, and water leaks—were common among affected children, present in 52% of undiagnosed cases and 38% of diagnosed ones.
Researchers emphasize that early detection through routine screening, combined with addressing environmental triggers, can improve outcomes and reduce health disparities, especially in vulnerable communities.
Findings are preliminary and await peer-reviewed publication.
