The continuing problem of asthma in very young children: a community-based participatory research project.

Background: Asthma is a chronic health condition that has a disproportionate effect on low-income minority children who reside in large urban areas. African-American children report significantly higher rates than the general population of children and have more-severe asthma and poorer outcomes. This article describes the prevalence of asthma in a particularly vulnerable group: children aged 2-5 participating in Detroit Head Start programs.
