Strategies behind the establishment of a developmental cohort study in the Tottori City.

Background: The Tottori study group, part of the JCS, presides over a community-based cohort study started when subjects-children living in Tottori City-were 5 years old. The social aspects of conducting a cohort study should also be made public, as this information is crucial for conducting community-based cohort studies.

Methods: Documents pertaining to social aspects implemented by the Tottori study group between 2004 and 2008 were arranged chronologically.
