FYI: City health officials and lower Manhattan politicos announced this morning the kick-off of the World Trade Center Health Registry, a 20-year project to track the physical and mental health effects of the towers’ collapse. Officials are encouraging anyone who was below Chambers at the time of the attack; who worked on the clean-up in the ensuing nine months; who lived below Canal at the time or who was a student in a school or daycare center below Canal on 9/11 to sign up for the registry, whether that person has health problems or not. Participants will take a 30-minute phone survey and be contacted periodically for follow-up information. The data collected will be compared with the general population and the findings will be posted quarterly online, starting this fall. Officials say the project is the largest health registry every attempted. [9/5/03]
