Family (vs. elderly) designated PHDs with more than 200 residents which were not undergoing renovations requiring residents to move out of the development for a period of time in the City of Boston were eligible to participate in this study (n=24). The investigators recruited 10 developments to participate in the Healthy Families study; 5 serving as intervention PHDs and 5 serving as control PHDs. PHDs were randomly assigned to either condition, in matched pairs for size of development and existence of health activities in the development. PHDs randomized to the intervention group received all intervention components (see Intervention section below) and developments randomized to the control group did not receive any intervention components.
