Many lifestyle interventions that are available in the Netherlands are collected in the Intervention Database Healthy and Active Living. This database is a joint initiative of the Dutch Institute for Sport and Movement (NISB) and RIVM Centre for Healthy Living (CGL), in collaboration with the Trimbos Institute. There are more than 1,800 interventions spread over many lifestyle themes. Owners of interventions put their offerings in the database so that professionals in the field can choose to work with.
