Intense or prolonged exposure to the World Trade Center attack has led to a large number of people reporting new health problems years later, a new research article has revealed.
Published in the August 5 issue of JAMA, the study has shown that individuals like recovery and rescue workers, nearby residents and office workers, who experienced intense or prolonged exposure to the World Trade Center attack, have reported new diagnoses of asthma or posttraumatic stress 5-6 years after the attack.
"The September 11, 2001, terrorist attack on the World Trade Center (WTC) killed thousands and exposed hundreds of thousands to horrific events and potentially harmful environmental conditions resulting from the collapsing towers and fires," according to background information in the article.
The report says that studies have documented adverse respiratory and mental health conditions associated with direct exposure within 1 to 3 years following the event, but the longer-term impact on health has been unclear.
Dr. Robert M. Brackbill, of the Centers for Disease Control and Prevention, Atlanta, and colleagues of the New York City Department of Health and Mental Hygiene, and Columbia University, New York, examined the incidence of two of the most commonly reported health outcomes: asthma and posttraumatic stress (PTS) symptoms indicative of probable posttraumatic stress disorder (PTSD) among adults 5 to 6 years after the attack.
For their study, the researchers used data from the World Trade Center Health Registry, the largest post-disaster exposure registry in U.S. history, which prospectively follows a group that reported a range of WTC disaster-associated exposures on September 11 and during its immediate aftermath.
