Neighbors Connected is a community-based intervention in the Netherlands. It helps the active older people to organize social activities for their less active older neighbors, facilitated by practical and financial support from the Community Health Service. The intervention is the outcome of a combination of semi-structured interviews with the older people, with organizations for older people and with local policy-makers, epidemiological data and interactive discussions, all of which support the notion that engaging in social activities is a way to enhance healthy ageing within the community. The use of different sources of evidence resulted in a comprehensive picture and actionable local knowledge.
