Lay Health Advisors. The intervention components were coordinated by residents of public housing who had completed a 14-week training in community health outreach, a long-standing program (12+ years) provided by the PHH-PRC. Upon completion, these lay health advisors complete a six month paid internship in their public housing development, distributing health information on a variety of topics of concern to residents and helping to link residents to neighborhood health- and clinical-related resources. From the pool of approximately 100 lay health advisors, a subset was selected to be trained in obesity-specific knowledge and procedures to serve in the Healthy Families intervention. They completed an additional 3-day training covering research processes (e.g., protecting participant privacy), study-specific protocols, and obesity management (e.g., health implications of obesity, effective approaches to supporting weight loss) and passed a post-training assessment to demonstrate their knowledge. Upon completion, these trained residents, called Healthy Living Advocates (HLAs) (n=5), served to coordinate the Healthy Family activities, described below, in the 5 intervention developments.
