Three case examples of asthma studies that differ in terms of community and involvement are considered. The Boston Chinatown studies faced limited funding that restricted the level of community involvement, but resulted in some of the first published evidence about asthma in Asian American children. These studies led to an asthma education program grant to a local Asian clinic and elementary school. The public housing study was a well-funded multi-year study of asthma and pest management with city, university and community partners. Residents were trained to collect data and participated throughout the study. Follow up pest management and pesticide buy-back programs headed by the city and community partners have been funded. The Dorchester case had more limited funding, but had the greatest level of involvement of parents of asthmatic children in all phases of the research. This survey led to an interesting novel finding of lower asthma prevalence in foreign born black residents.
