On February 25th of 2020, an online meeting was held with the primary investigator and managerial and executive members of the PERSIAN Birth Cohort. In this meeting, all locals presented a brief report on the status of the project in their region. Problems regarding project implementation were debated and attendees were invited to discuss their suggested solutions.  Also, the status of the protocol development and editing were reviewed. Then members were encouraged to share their ideas on the previously suggested topics to perform more sub studies from the main project.
