The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. John L. Anderson is president.
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.
The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the study’s statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committee’s deliberations. Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task.
Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies.

Reviewers
This Consensus Study Report was reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise. The purpose of this independent review is to provide candid and critical comments that will assist the National Academies of Sciences, Engineering, and Medicine in making each published report as sound as possible and to ensure that it meets the institutional standards for quality, objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process.
We thank the following individuals for their review of this report:
Although the reviewers listed above provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations of this report, nor did they see the final draft before its release. The review of this report was overseen by SANDRO GALEA, Boston University School of Public Health, and DAVID A. SAVITZ, Brown University. They were responsible for making certain that an independent examination of this report was carried out in accordance with the standards of the National Academies and that all review comments were carefully considered. Responsibility for the final content rests entirely with the authoring committee and the National Academies.

Acknowledgments
The committee could not have written this report without the help of a number of people. We wish to particularly thank the presenters and participants in our October 2019 workshop—listed in Appendix A—who shared their expertise and perspectives on respiratory health issues in veterans and the research that might allow a better understanding of them. Drs. R. Loren Erickson and Eric Shuping of the Department of Veterans Affairs also briefed the committee and responded to our follow-up questions.
The committee members are very appreciative of the outstanding efforts of the staff of the National Academies of Sciences, Engineering, and Medicine’s Health and Medicine Division, who supported us in our work, David Butler, who served as study director; and Elizabeth Boyle, Christina Samuel, Anne Styka, Kristin White, and Stephanie Hanson, who had a daunting task of identifying and culling the large and complex literature we reviewed and more generally guiding and assisting the committee in its mission. We are also very grateful to Rebecca Chevat for capably providing logistical support. Finally, we would like to acknowledge Jorge Mendoza, a senior research librarian who conducted the literature searches for the committee, and Misrak Dabi, the financial business partner for the project.
