World Trade Center Adolescent Health Study
Early Identification of World Trade Center Conditions in Adolescents
Aperçu de l'étude
Statut
Description détaillée
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).

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.

Description de la mesure |
Délai |
---|---|---|
Pulmonary Function Testing
Délai: One time
|
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.
|
One time
|
Oscillometry
Délai: One time
|
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.
|
One time
|
Plethysmography
Délai: One time
|
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.
|
One time
|
Blood Pressure
Délai: One time
|
We will perform assess systolic (first Korotkoff phase) and diastolic (fifth Korotkoff phase) BP three consecutive times in all participants.
|
One time
|
Arterial Wall Stiffness
Délai: One time
|
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.
|
One time
|
Heart Rate Variability
Délai: One time
|
Assessment of Heart Rate Variability (HRV) will be performed using the SphgymoCor SCOR-CPV device (AtCor Medical, Sydney, Australia).
|
One time
|
Insulin resistance
Délai: One time
|
Fasting insulin and blood glucose will be assessed.
|
One time
