About this study
Official title: Early Identification of World Trade Center Conditions in Adolescents
The proposed study builds upon preliminary studies in self-selected populations to identify opportunities for early identification of World Trade Center-related health consequences in adolescents. If adverse health consequences are identified, proactive cardiometabolic and pulmonary screening of exposed children may be indicated, with targeted interventions intended to prevent development of chronic obstructive pulmonary disease, and adverse cardiometabolic outcomes in adulthood.
Read the detailed description
The study will assess the potential for longer-latency cardiometabolic and pulmonary effects of early life exposure to the World Trade Center (WTC) disaster, and to identify opportunities for early identification of WTC-related health consequences. Preliminary data from the only investigators who regularly provide clinical care to children who lived/attended school near the WTC site identified decrements in spirometry associated with dust cloud exposure, and a remarkably high frequency of cardiometabolic risk factors. Findings from this clinically, self-selected population cannot be extrapolated to the entire population of children who were exposed to the disaster but nonetheless suggest that further study is warranted of the possible metabolic and cardiovascular consequences of WTC exposures. If associated with WTC exposures in a larger, more representative sample, two new and innovative techniques, oscillometry and pulse wave velocity assessment, hold great promise for earlier detection of WTC-related pulmonary and cardiometabolic disease, for whom dietary, environmental and medication interventions may prevent disease progression in later life.
The study will recruit 225 adolescents who respond to the WTC Health Registry (WTCHR), the most representative pediatric population and best-characterized from an environmental exposure standpoint. Connecting the study to the WTCHR also presents efficiency of federal resource utilization, providing more objective clinical data to support self-reported findings of increased persistent respiratory symptoms captured by the WTCHR, thereby improving reliability of the registry data. We will compare pulmonary and cardiometabolic outcomes to carefully matched (age, race/ethnicity, gender, and socioeconomic status) and unexposed control (not resident/attending school south of Houston Street on September 11, 2001) populations from NYU School of Medicine affiliated primary care (private and public clinics).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| World Trade Center exposed group | After informed consent, anthropometric and blood pressure/brachial artery distensibility assessments; physical examination and environmental and respiratory history questionnaire completion; heart rate variability measurement; and spirometry/IOS will be performed on the World Trade Center exposed group. A research assistant well trained in pediatric phlebotomy will collect 23 mL of fasting blood. Spirometry and IOS, diet diary collection, lung volumes by plethysmography, and arterial wall stiffness. | |
| Unexposed comparison group | After informed consent, anthropometric and blood pressure/brachial artery distensibility assessments; physical examination and environmental and respiratory history questionnaire completion; heart rate variability measurement; and spirometry/IOS will be performed on the unexposed comparison group. A research assistant well trained in pediatric phlebotomy will collect 23 mL of fasting blood. Spirometry and IOS, diet diary collection, lung volumes by plethysmography, and arterial wall stiffness. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pulmonary Function Testing
We will perform spirometry according to standards outlined by the American Thoracic Society and the European Respiratory Society. Specifically, we will assess forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, and forced expiratory flow over 25-75% of the vital capacity (FEF25-75%; Jaeger Masterscreen IOS; Carefusion, Yorba Linda, CA). National Health and Nutrition Examination Survey (NHANES) III reference equations will be used to determine normative values, with statistical analysis to be applied to percents of predicted volumes based on these norms.
Measured: One time
Oscillometry
Oscillometry provides a noninvasive measure of the impedance to airflow within the lung. An externally-generated pressure impulse is applied during tidal breathing in a seated position for 30 seconds, and volume and flow measurements are made.
Measured: One time
Plethysmography
Measured lung volumes will include total lung capacity (TLC), vital capacity (VC), residual volume (RV), and functional residual capacity (FRC) and will be compared to normative values, using established pediatric reference equations.
Measured: One time
Blood Pressure
We will perform assess systolic (first Korotkoff phase) and diastolic (fifth Korotkoff phase) BP three consecutive times in all participants.
Measured: One time
Arterial Wall Stiffness
Pulse Wave Velocity (PWV) will be measured using the SphygmoCor CPV System (AtCor Medical, Sydney, Australia). PWV measures the speed for the pressure wave generated by cardiac ejection to reach the periphery.
Measured: One time
Heart Rate Variability
Assessment of Heart Rate Variability (HRV) will be performed using the SphgymoCor SCOR-CPV device (AtCor Medical, Sydney, Australia).
Measured: One time
Insulin resistance
Fasting insulin and blood glucose will be assessed.
Measured: One time
Secondary outcomes (3)
Lipid levels
Fasting blood draw will be performed.
Measured: One time
Psychosocial stress and mental health outcomes
- WTC disaster trauma-We will measure psychologically relevant WTC exposure, using questions about direct exposure, family/friend exposure, and media exposure.
- Other lifetime trauma
- Depression
- Substance abuse, and other diagnoses
- Post-traumatic stress disorder
- Functional impairment
- Mental health service utilization
Measured: One time
Tobacco smoke exposure
We will measure tobacco smoke exposure from salivary cotinine.
Measured: One time

Questions about this trial
What is this clinical trial studying?
An observational study of Asthma and Hypertension, run by NYU Langone Health at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pulmonary Function Testing (time frame: One time). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02068183, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jan 2017.
