Unhealthy housing is a major cause of respiratory health inequity. In-home health education improves health equity for low-income and minority populations with asthma and chronic obstructive pulmonary disease. Yet, outcomes of educational interventions are limited by poor housing conditions. Federal weatherization programs represent a promising source of funding for home repairs. Innovative legislation in Washington State integrates the 2 interventions as "Weatherization Plus Health," offering environmental health education in partnership with the Weatherization Assistance Program for low-income families with respiratory disease. This practice brief describes process evaluation results of a Weatherization Plus Health program in Pierce County, Washington. Evaluation data were gathered via interviews with service providers and ethnographic observation. Workers report that the combined intervention expanded their understanding of their practice, skills, and feelings of efficacy in meeting client needs. Integrating federally funded home weatherization with health education shows promise for building public health system capacity and increasing health equity.
