I know there have been a few of us here (those of us in the NY or DC areas) 
that directly experienced the events of 9/11. There's an interesting study 
recently released that suggests that some people are still significantly 
affected by PTSD related to 9/11

Post-trauma stress lingers in NYC 9/11 survivors
- August 04, 2009

NEW YORK - People who were heavily exposed to the Sept. 11 attacks on the World 
Trade Center had elevated risks of developing post-traumatic stress disorder 
symptoms even five years later, about four times that of the general public, 
according to a study released Tuesday.

The study by the city's Department of Health and Mental Hygiene found elevated 
levels of PTSD symptoms among the more than 46,000 people who were surveyed in 
2006-2007. The study is based on data from a public health registry that tracks 
the health effects of Sept. 11.

Among survey respondents, 19 percent reported having symptoms, about four times 
the rate usually seen among adults. When the registry first surveyed people in 
2003-2004, it was 14 percent.

Some in the first survey got better, while some remained where they were, and 
others got worse, said Lorna Thorpe, deputy commissioner for epidemiology and a 
co-author of the study.

"This is really the largest burden in terms of health conditions," Thorpe said.

The study found that more than half of the participants who reported having 
stress symptoms said they had not obtained treatment in the past year. The 
registry has begun outreach to get survey respondents referred for medical 
help, and the city offers free physical and mental health care to eligible 
people affected by the attacks.

Passers-by such as commuters and tourists were the most heavily affected, with 
23 percent of them reporting symptoms in the latest survey.

The study contained better news about asthma. While those who developed 
respiratory symptoms soon after the attacks were still being diagnosed with 
asthma some years later, rates among people who first showed symptoms after 
2003 were consistent with normal asthma rates.

"What this study shows fairly thoroughly, there was a very strong association 
between the intense exposure" on Sept. 11 and the days immediately following, 
in terms of developing asthma, Thorpe said. "There were lingering effects, but 
those lingering effects have ameliorated."

While asthma cases rose most sharply right after attacks, they were still being 
diagnosed after some years had passed. The study found that 10 percent of 
participants had been newly diagnosed with the condition between the attacks 
and the 2006-2007 survey period.

Rescue and recovery workers had the highest rates of new asthma diagnoses, and 
their risk was even higher if they were at the World Trade Center site on 9/11 
itself or worked there for longer than 90 days. People who had to deal with 
heavy layers of dust in their homes or offices also had a higher risk of 
developing asthma.

The World Trade Center Health Registry was established in 2003 to track the 
long-term health effects of ground zero exposure on workers, volunteers, and 
residents. More than 71,000 people registered, and surveys on their health 
status was collected in 2003-2004 and 2006-2007. More than 46,000 registrants 
took part in both surveys.

The study was conducted by the health department and the federal Centers for 
Disease Control and was released in the Journal of the American Medical 
Association.
