workshop. More than 40 experts in the field addressed important questions during formal presentations.

The workshop also offered an opportunity for presenters, participants, and the public to contribute to the discussion of the relationship between food insecurity and obesity. The workshop itself engendered many exchanges between presenters and other participants, which are summarized in the sections labeled “Group Discussion” in this report. Additionally, roundtable discussions were held at the end of the first day of the workshop with the goal of eliciting ideas from participants on how better to understand the relationship between food insecurity and obesity. Participants split into a number of small groups to discuss specific questions related to that goal, and the summary is in Appendix F of this report. Finally, after the workshop concluded, its participants and the general public had the opportunity to submit comments on the topic to a section of the IOM website.

The workshop created a dialogue among people who might not normally be talking with each other in depth: specialists focused on hunger and specialists focused on overweight/obesity, academics and activists, and qualitative and quantitative researchers. In so doing, the workshop underscored the importance of this kind of broad communication.

This workshop summary is organized according to the chronological order of the proceedings, except for notes from roundtable discussions, which are found in Appendix F. The goals of the workshop are presented in Chapter 1, followed by a stage-setting chapter that examines the evidence on the relationship between food insecurity and obesity in adults and in children. Chapter 3 examines the food insecurity and obesity relationship as it is influenced by socioeconomic disparities. Chapter 4 examines the relationship in sentinel populations, including young children, immigrants, Native Americans, and rural populations. Chapters 5 through 8 walk through four levels of a socioecological model—individual, family and household, environmental, and institutional, respectively, and Chapter 9 discusses a framework to integrate the perspectives of the four levels. Research applications that target both food insecurity and obesity are discussed in Chapter 10. Chapter 11 explores major research questions, from the perspective of four disciplines—nutrition, sociology, psychology/human development, and economics—that if addressed will likely help us to better understand the relationship between food insecurity and obesity and may help the research and policy communities integrate these disciplinary perspectives when designing programs and policies. Chapter 12 describes research methods and measures that may be useful in addressing the research gaps identified throughout the workshop, including strategies such as data modeling, qualitative research, and geographic information system mapping. Chapter 13 conveys the perspectives of government agencies and foundations on research priorities and considers how to address proposed priorities, as well
