Public Health Systems and Social Services: Breadth and Depth of Cross-Sector Collaboration.

Objectives. To examine the extent to which social service organizations participate in the organizational networks that implement public health activities in US communities, consistent with recent national recommendations.Methods. Using data from a national sample of US communities, we measured the breadth and depth of engagement in public health activities among specific types of social and community service organizations.Results. Engagement was most prevalent (breadth) among organizations providing housing and food assistance, with engagement present in more than 70% of communities. Engagement was least prevalent among economic development, environmental protection, and law and justice organizations (less than 33% of communities). Depth of engagement was shallow and focused on a narrow range of public health activities.Conclusions. Cross-sector relationships between public health and the housing and food sectors are now widespread across the United States, giving most communities viable avenues for addressing selected social determinants of health. Relationships with many other social and community service organizations are more limited.Public Health Implications. Public health leaders should prioritize opportunities for engagement with low-connectivity social sectors in their communities such as law, justice, and economic development.
