Scientific value of the sub-cohort of children in the World Trade Center Health Registry
Brackbill RM , Butturini E , Cone JE , Ahmadi A , Daniels RD , Farfel MR , Kubale T . Int J Environ Res Public Health 2022 19 (19) The World Trade Center Health Registry (WTCHR) was established in 2002 as a public health resource to monitor the health effects from the World Trade Center (WTC) disaster. We evaluated the representativeness of the WTC youth population (<18 years on 11 September 2001) by comparing the distributions of age, gender, race/ethnic groups, and income to 2000 census data for the matched geographic area, including distance from disaster. There were 2379 WTCHR enrolled children living in Lower Manhattan south of Canal Street on 11 September 2001, along with 752 enrolled students who attended school in Lower Manhattan but were not area residents. The WTCHR sub-group of children who were residents was similar to the geographically corresponding census population on age and sex. Black and Hispanic children are moderately overrepresented at 0.9% and 2.4% in the WTCHR compared to 0.8% and 1.7% in census population, respectively, while lower-income households are slightly under-represented, 28.8% in the WTCHR and 30.8% for the corresponding census information. Asian children appear underrepresented at 3.0% participation compared to 6.3% in the census. While the demographics of WTCHR youth are somewhat skewed, the gaps are within expected patterns of under-representation observed in other longitudinal cohorts and can be effectively addressed analytically or through targeted study design. |
Editorial for "Long-Term Health Effects of the 9/11 Disaster" in International Journal of Environmental Research and Public Health, 2019
Brackbill RM , Graber JM , Robison WAA . Int J Environ Res Public Health 2019 16 (18) The call for articles on the long term health effects of the 11 September 2001 terrorist attacks (9/11) has resulted in twenty-three papers that add a significant amount of information to the growing body of research on the effects of the World Trade Center (WTC) disaster almost two decades later [...]. |
9/11 residential exposures: the impact of World Trade Center dust on respiratory outcomes of lower Manhattan residents
Antao VC , Pallos LL , Graham SL , Shim YK , Sapp JH , Lewis B , Bullard S , Alper HE , Cone JE , Farfel MR , Brackbill RM . Int J Environ Res Public Health 2019 16 (5) Thousands of lower Manhattan residents sustained damage to their homes following the collapse of the Twin Towers on 11 September 2001. Respiratory outcomes have been reported in this population. We sought to describe patterns of home damage and cleaning practices in lower Manhattan and their impacts on respiratory outcomes among World Trade Center Health Registry (WTCHR) respondents. Data were derived from WTCHR Wave 1 (W1) (9/2003(-)11/2004) and Wave 2 (W2) (11/2006(-)12/2007) surveys. Outcomes of interest were respiratory symptoms (shortness of breath (SoB), wheezing, persistent chronic cough, upper respiratory symptoms (URS)) first occurring or worsening after 9/11 W1 and still present at W2 and respiratory diseases (asthma and chronic obstructive pulmonary disease (COPD)) first diagnosed after 9/11 W1 and present at W2. We performed descriptive statistics, multivariate logistic regression and geospatial analyses, controlling for demographics and other exposure variables. A total of 6447 residents were included. Mean age on 9/11 was 45.1 years (+/-15.1 years), 42% were male, 45% had ever smoked cigarettes, and 44% reported some or intense dust cloud exposure on 9/11. The presence of debris was associated with chronic cough (adjusted OR (aOR) = 1.56, CI: 1.12(-)2.17), and upper respiratory symptoms (aOR = 1.56, CI: 1.24(-)1.95). A heavy coating of dust was associated with increased shortness of breath (aOR = 1.65, CI: 1.24(-)2.18), wheezing (aOR = 1.43, CI: 1.03(-)1.97), and chronic cough (aOR = 1.59, CI: 1.09(-)2.28). Dusting or sweeping without water was the cleaning behavior associated with the largest number of respiratory outcomes, such as shortness of breath, wheezing, and URS. Lower Manhattan residents who suffered home damage following the 9/11 attacks were more likely to report respiratory symptoms and diseases compared to those who did not report home damage. |
Respiratory protective equipment, mask use, and respiratory outcomes among World Trade Center rescue and recovery workers
Antao VC , Pallos LL , Shim YK , Sapp JH 2nd , Brackbill RM , Cone JE , Stellman SD , Farfel MR . Am J Ind Med 2011 54 (12) 897-905 BACKGROUND: Serious respiratory illnesses have been reported among rescue/recovery workers (RRW) following the World Trade Center (WTC) attacks. METHODS: We studied RRW enrolled in the WTC Health Registry to assess the effects of different respiratory protection equipment (RPE) types on respiratory outcomes, such as recurrent respiratory symptoms and diseases possibly associated with 9/11 exposures. We performed descriptive and multivariate analyses adjusting for demographics and exposure variables. RESULTS: A total of 9,296 RRW met inclusion criteria. The strongest predictors of using adequate RPE were being affiliated with construction, utilities or environmental remediation organizations and having received RPE training. Workers who used respirators were less likely to report adverse respiratory outcomes compared to those who reported no/lower levels of respiratory protection. CONCLUSIONS: Level of respiratory protection was associated with the odds of reporting respiratory symptoms and diseases. Training, selection, fit testing, and consistent use of RPE should be emphasized among emergency responders. Am. J. Ind. Med. (c) 2011 Wiley-Liss, Inc. |
Asthma and posttraumatic stress symptoms 5 to 6 years following exposure to the World Trade Center terrorist attack
Brackbill RM , Hadler JL , DiGrande L , Ekenga CC , Farfel MR , Friedman S , Perlman SE , Stellman SD , Walker DJ , Wu D , Yu S , Thorpe LE . JAMA 2009 302 (5) 502-16 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) terrorist attack. DESIGN, SETTING, AND PARTICIPANTS: Longitudinal cohort study with wave 1 (W1) enrollment of 71,437 adults in 2003-2004, including rescue/recovery worker, lower Manhattan resident, lower Manhattan office worker, and passersby eligibility groups; 46,322 adults (68%) completed the wave 2 (W2) survey in 2006-2007. MAIN OUTCOME MEASURES: Self-reported diagnosed asthma following September 11; event-related current PTS symptoms indicative of probable posttraumatic stress disorder (PTSD), assessed using the PTSD Checklist (cutoff score > or = 44). RESULTS: Of W2 participants with no stated asthma history, 10.2% (95% confidence interval [CI], 9.9%-10.5%) reported new asthma diagnoses postevent. Intense dust cloud exposure on September 11 was a major contributor to new asthma diagnoses for all eligibility groups: for example, 19.1% vs 9.6% in those without exposure among rescue/recovery workers (adjusted odds ratio, 1.5 [95% CI, 1.4-1.7]). Asthma risk was highest among rescue/recovery workers on the WTC pile on September 11 (20.5% [95% CI, 19.0%-22.0%]). Persistent risks included working longer at the WTC site, not evacuating homes, and experiencing a heavy layer of dust in home or office. Of participants with no PTSD history, 23.8% (95% CI, 23.4%-24.2%) reported PTS symptoms at either W1 (14.3%) or W2 (19.1%). Nearly 10% (9.6% [95% CI, 9.3%-9.8%]) had PTS symptoms at both surveys, 4.7% (95% CI, 4.5%-4.9%) had PTS symptoms at W1 only, and 9.5% (95% CI, 9.3%-9.8%) had PTS symptoms at W2 only. At W2, passersby had the highest rate of PTS symptoms (23.2% [95% CI, 21.4%-25.0%]). Event-related loss of spouse or job was associated with PTS symptoms at W2. CONCLUSION: Acute and prolonged exposures were both associated with a large burden of asthma and PTS symptoms 5 to 6 years after the September 11 WTC attack. |
