Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council.

This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the National Research Council’s Report Review Committee. The purpose of this independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and to ensure that the report meets institutional standards for 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 wish to thank the following individuals for their review of this report:

Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations nor did they see the final draft of the report before its release. The review of this report was overseen by Jane E. Sisk, Centers for Disease Control and Prevention and Elena O. Nightingale, Institute of Medicine. Appointed by the National Research Council and Institute of Medicine, they were responsible for making certain that an independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution.
Developing this report about facilitating integrated research on how the social environment and genetic function affect health outcomes has been tremendously rewarding, in large part because the effort was a collaboration among scientists from the social, behavioral, and biological sciences. Committee research and discussion illuminated associations among social factors and health, behaviors and health, and genetics and health. Committee collaboration resulted in a vision, described in this report, of how future research, transdisciplinary in nature, can contribute to the science of gene-social environment interactions and to explaining individual and population health and health disparities.
Yet, transdisciplinary research faces many challenges, not the least of which are those encountered when attempting to conduct collaborative research across disciplines. In a sense, the challenge of collaboration was illustrated in the work of this committee, whose scientists came from the fields of sociology, demography, psychology, psychiatry, research design, law, ethics, medicine, public health, epidemiology, biology, molecular virology, and genetics. Despite the fact that each committee member already had demonstrated a willingness to work with those from other disciplines on problems that crossed social, behavioral, and genetic lines, committee understanding and collaboration were not achieved effortlessly. Research conducted by different disciplines rests on different knowledge bases, often with different areas of focus—for example, the geneticist emphasizes individuals, while sociologists examine groups and societies. To form a group that could work collaboratively, it was necessary to devote meeting time to
developing a common understanding of each others’ definitions, terms, knowledge about what various disciplines have contributed to our understanding of disease risk, and an appreciation and value for the research designs and methods used by practitioners of the different disciplines. It was only after this had been accomplished that rapid progress could be made in developing an integrated approach to the task at hand—that of determining how researchers can begin to assess the impact on health of interactions among social, behavioral, and genetic factors.
In transdisciplinary research, investigators will be faced, on a broader scale, with the challenges that confronted this committee. Foremost among these challenges is the need to appreciate and value the contributions of other disciplines. Other challenges and approaches to addressing them are described in the body of the report, but the committee believes that the challenge of fostering true collaboration merited the emphasis that is provided in this preface. Successful transdisciplinary research that is conducted on gene-social environment interaction could provide a way for us to redefine how we think about health and disease. Such a redefinition, however, is not a short trip going forward with a specific goal in mind; rather, it is a journey that will require time and patience. This report and its recommendations are intended to launch us on that journey.
