METHOD Rescue and recovery workers enrolled in the World Trade Center Health Registry who reported working at the World Trade Center site(More)
CONTEXT The World Trade Center Health Registry provides a unique opportunity to examine long-term health effects of a large-scale disaster. OBJECTIVE To examine risk factors for new asthma diagnoses and event-related posttraumatic stress (PTS) symptoms among exposed adults 5 to 6 years following exposure to the September 11, 2001, World Trade Center (WTC)(More)
BACKGROUND Studies have consistently documented declines in respiratory health after 11 September 2001 (9/11) among surviving first responders and other World Trade Center (WTC) rescue, recovery, and clean-up workers. OBJECTIVES The goal of this study was to describe the risk of newly diagnosed asthma among WTC site workers and volunteers and to(More)
To date, health effects of exposure to the September 11, 2001 disaster in New York City have been studied in specific groups, but no studies have estimated its impact across the different exposed populations. This report provides an overview of the World Trade Center Health Registry (WTCHR) enrollees, their exposures, and their respiratory and mental health(More)
In 1992, the U.S. Congress passed the Residential Lead-Based Paint Hazard Reduction Act, which requires the promulgation of health-based dust lead and soil lead standards for residential dwellings to prevent undue lead exposure in children. Unfortunately, the levels of lead in house dust and soil that are associated with elevated blood lead levels among(More)
Manhattan residents living near the World Trade Center may have been particularly vulnerable to posttraumatic stress disorder (PTSD) after the September 11, 2001 (9/11) terrorist attacks. In 2003-2004, the authors administered the PTSD Checklist to 11,037 adults who lived south of Canal Street in New York City on 9/11. The prevalence of probable PTSD was(More)
BACKGROUND Co-occurrence of lower respiratory symptoms (LRS) and posttraumatic stress disorder (PTSD) has been increasingly recognized among responders and survivors of the World Trade Center (WTC) disaster. Information is limited on the degree which comorbidity intensifies symptoms and compromises quality of life across exposed groups. METHODS Among(More)
We examined changes in ambient dust lead (Pb) levels associated with the demolition of older row houses containing lead paint in Baltimore, MD, USA. Our previous paper describes the three study sites, the demolition processes, and increases in the Pb dustfall rate during demolition (>40-fold) and debris removal (>6-fold) within 10 m of sites where wetting(More)
PROBLEM/CONDITION Survivors of collapsed or damaged buildings from the attack on the World Trade Center (WTC) were among those most exposed to injury hazards, air pollution, and traumatic events. REPORTING PERIOD This report summarizes data from health outcomes collected during interviews conducted from September 5, 2003, to the close of the World Trade(More)
BACKGROUND Volunteers (non-professional rescue/recovery workers) are universally present at man-made and natural disasters and share experiences and exposures with victims. Little is known of their disaster-related health outcomes. METHODS We studied 4974 adult volunteers who completed the World Trade Center Health Registry 2006-07 survey to examine(More)
