Description:

Objective:

This on-going project was developed in response to RFA 2000-02 entitled “Association between Exposures to Oxygenated Air Toxics and Asthma: An Exposure and Health Effects Study of Houston Area School Children.” The three year study began in December 2001.

The study is in compliance with the Institutional Review Board of the University of Texas. Human consent procedures met governmental guidelines. The study is also in compliance with appropriate quality control and quality assurance procedures as per NUATRC and EPA guidelines.

The objective of this project was to conduct a prospective, pilot panel study to investigate the association between exposure to oxygenated air toxics (total carbonyl concentration) and asthma health outcomes among labile, persistent asthmatic middle school children in Houston, using a repeated measures design over a 12-month period. The study population NUATRCs on labile, persistent asthmatics on the basis that they were likely to manifest greater variability in health outcomes following exposure to airborne stimuli. The study design is one of repeated measures of health outcomes and relevant exposure variables over time, in which each participant serves as her/his own control. Four 1-week measurement periods, for each of the main independent (exposure) and dependent (health outcome) variables were to be performed over a 12-month observation period. Repeated measurements of established confounder variables were also to be performed serially over the 12-month period.

Progress Summary:

The NUATRC received a revised draft final report on October 6, 2005 it was reviewed by the SAP subgroup and a team of four external peer-reviewers: A letter summarizing the SAP subgroups overall comments and the external reviewers’ reviews were sent to Dr. Delclos. A third revised version of the report was received in August of 2006. The report was reviewed by the SAP subgroup. They found the report to be improved, but further clarification is recommended on his responses and the carbonyl measurements.
