The World Trade Center Clean Up and Recovery Worker Cohort Study: Respiratory Health Amongst Cleanup Workers Approximately 20 Months After Initial Exposure at the Disaster Site

Abstract

These results suggest an impact on respiratory health related to work experience at the WTC and indicate further monitoring to address potential long-term effects.

Asthma and lower respiratory symptoms in New York State employees who responded to the World Trade Center disaster

“…Our response rates are similar to other WTC studies Tao et al 2007). In particular, our experience was similar to that described by Tao et al (2007), who also reported a low response rate that diVered by exposure groups.…”

“…In particular, our experience was similar to that described by Tao et al (2007), who also reported a low response rate that diVered by exposure groups. It is often believed that persons with health symptoms are more likely to respond to health surveys.…”

“…It is often believed that persons with health symptoms are more likely to respond to health surveys. By employing the sensitivity analysis they used to assess possible selection bias (Tao et al 2007), we similarly found that our eVect estimates may be underestimates of the true eVect if, in fact, those with more symptoms were more likely to respond. In other studies, a response rate could not be calculated due to missing denominator data or recruitment procedures (Herbstman et al 2005;Skloot et al 2004;WolV et al 2005).…”

What Occupational Health Needs Arise in Workplaces Following Disasters? A Joint Analysis of Eight Cases of Disaster in Japan

“…Many studies have examined exposure to health hazards [6][7][8][9][10][11][12] and traumatic stress after disasters, 15-24 but few have analyzed disaster-related occupational health needs in workplaces. [25][26][27] This may be because companies are reluctant to disclose data even when various occupational health needs have arisen.…”

“…With regard to health issues related to disasters, many studies have been conducted on the long-term health effects on emergency responders, [6][7][8][9][10][11][12] health effects on local residents after accidents at chemical plants, 13,14 and programs dealing with traumatic stress. [15][16][17][18][19][20][21][22][23][24] Except for studies by external occupational health experts examining the occupational health needs arising at workplaces during large-scale disasters, 25,26 few case reports on this matter have been published.…”
