Changing the housing environment to reduce obesity in public housing residents: a cluster randomized trial.

BACKGROUND: Public housing residents face significant social, economic, and physical barriers to the practice of health behaviors for prevention of chronic disease. Research shows that public housing residents are more likely to report higher rates of obesity, current smoking, disability, and insufficient physical activity compared to individuals not living in public housing. Because these behaviors and conditions may be shaped by the built and social environments in which they live, we conducted a study to test an environmental level diet and physical activity intervention targeting obesity among urban public housing developments. METHODS: This study was a cluster randomized controlled trial of public housing developments, the unit of analysis and randomization. A total of 10 public housing developments were recruited and subsequently randomized to either receive the intervention package or to serve as comparison sites. The year-long intervention included components to change the dietary and physical activity-related environments of the developments. Surveys at baseline and one-year follow-up provided data on changes in behaviors and weight from participants in both intervention and control developments. RESULTS: Intervention participants significantly changed their eating and activity behaviors and body weight from baseline to one-year follow-up (p's < .05) while comparison participants reported no significant changes in any study variable. CONCLUSIONS: These data provide initial support for the idea that interventions targeting the environment of public housing developments can assist residents to change unhealthy behaviors and can possibly reduce the high levels of chronic disease among public housing residents.

Resident health advocates in public housing family developments.

Translation of research to practice often needs intermediaries to help the process occur. Our Prevention Research Center has identified a total of 89 residents of public housing in the last 11 years who have been working in the Resident Health Advocate (RHA) program to engage residents in improving their own and other residents' health status by becoming trained in skills needed by community health workers. Future directions include training for teens to become Teen RHAs and further integration of our RHA program with changes in the health care system and in the roles of community health workers in general.

Enhancing physical and social environments to reduce obesity among public housing residents: rationale, trial design, and baseline data for the Healthy Families study.

Intervention programs that change environments have the potential for greater population impact on obesity compared to individual-level programs. We began a cluster randomized, multi-component multi-level intervention to improve weight, diet, and physical activity among low-socioeconomic status public housing residents. Here we describe the rationale, intervention design, and baseline survey data. After approaching 12 developments, ten were randomized to intervention (n=5) or assessment-only control (n=5). All residents in intervention developments are welcome to attend any intervention component: health screenings, mobile food bus, walking groups, cooking demonstrations, and a social media campaign; all of which are facilitated by community health workers who are residents trained in health outreach. To evaluate weight and behavioral outcomes, a subgroup of female residents and their daughters age 8-15 were recruited into an evaluation cohort. In total, 211 households completed the survey (RR=46.44%). Respondents were Latino (63%), Black (24%), and had ≤ high school education (64%). Respondents reported ≤2 servings of fruits & vegetables/day (62%), visiting fast food restaurants 1+ times/week (32%), and drinking soft drinks daily or more (27%). The only difference between randomized groups was race/ethnicity, with more Black residents in the intervention vs. control group (28% vs. 19%, p=0.0146). Among low-socioeconomic status urban public housing residents, we successfully recruited and randomized families into a multi-level intervention targeting obesity. If successful, this intervention model could be adopted in other public housing developments or entities that also employ community health workers, such as food assistance programs or hospitals.

Connecting Boston's public housing developments to community health centers: who's ready for change?

BACKGROUND: Despite close proximity to community health centers, public housing residents are at increased risk of uncontrolled chronic disease, in part because of underutilization of routine health care. OBJECTIVES: To assist in program planning, the Partners in Health and Housing Prevention Research Center (PHH-PRC) used the Community Readiness Model to compare readiness of public housing developments and community health centers to address community-identified health priorities. The model assumes that program success to affect change depends on matching the community's level of readiness to address the issue. METHODS: Key respondent interviews were conducted across 15 communities: Eight housing developments and seven health centers. Interviews were scored across six dimensions on an anchored, 9-point scale and averaged to provide a composite readiness score. Higher scores indicate increasing levels of readiness. Interview transcripts were reviewed for consistent themes. RESULTS: Health centers scored significantly higher (mean, 5.88) than housing developments (mean, 3.33), corresponding with the Preparation stage of readiness compared with the Vague Awareness stage, respectively. Both scored highest in Existing Programs and Resources and lowest in Knowledge of Efforts. Qualitative analysis revealed a lack of existing partnerships between housing developments and health centers as well as significant social barriers preventing housing residents from engaging in care. CONCLUSION: We found a mismatch in readiness to address community health priorities. Although health centers have programs to address health issues, community awareness of programs is limited and barriers to engaging in care persist. The model provided a useful tool for engaging communities into shared program planning.
