The registry, which is the largest survey in American history to track the health effects of a disaster, is aiming to get a better picture of how living through two major tragedies can affect both physical and mental health, said Michael Farfel, director of the WTC Registry, at a Community Board 1 meeting Thursday.
"I think this will be an important survey," Farfel said. "We're hoping many people will participate."
They hope to launch the survey, which will ask questions about mental illnesses including post-traumatic stress disorder, as well as physical ailments, in the first week of April.
The WTC Registry has more than 70,000 members, including more than 11,300 people who lived south of Canal Street on Sept. 11, 2001, and looks at the health effects on specific groups of people, including young children.
Data from two previous surveys, completed in 2004 and 2007, has informed many of the scientific studies about 9/11 health and helped secure the passage of the $4.3 billion James Zadroga 9/11 Health and Compensation Act, Farfel said.
Previous findings include elevated levels of post-traumatic stress disorder, along with an increase in respiratory illnesses, among Downtown residents and Ground Zero recovery workers.
The registry's most recent comprehensive survey launched in 2011 and was completed in March 2012. Findings from that survey will soon be published, Farfel said.
