Despite broad awareness of the role that diet plays in increasing obesity risk, adherence to
public health recommendations for maintaining healthy eating is low. Insights gained from
weight loss intervention trials find that trial participants report difficulty in restricting
calories, dissatisfaction with the pace of weight loss, inability to control eating, low
palatability of recommended foods and strong food cravings. Indeed, recent systematic reviews
provide empirical support that these subjective experiences that trial participants describe
likely represent eating-related traits or phenotypes . While amassing evidence supports
individual variation in these eating-related traits, to date there has been no systematic
effort to characterize robust eating-related phenotypes. Proposed is a Sub-study initially
planned to be piggy-backed on a planned Study being conducted by investigators at the
University of North Carolina (UNC-- Linnan, Dilworth- Anderson & Evans). The UNC Parent Study
was a feasibility study using community-based participatory research (CBPR) approaches to
explore possible intervention strategies aimed to reduce the burden of chronic disease and
cancer among African American families. The NHGRI-led eating behavior Sub-study is proposed
to be integrated with the UNC Parent Study (hereafter referred to as Phase 1). The additional
aims of the Sub-study (hereafter referred to as Phase 2) are to gain understanding of whether
we can characterize clusters of eating-related behaviors that may be associated with
adherence to weight management and weight outcomes. This current protocol lays out the
specific qualitative activities planned for Phase 1 which include conducting structured
interviews with Black Family Reunion organizers (N=8) and a sample of reunion participants
(N=40). We also describe the larger quantitative survey proposed for Phase 2. Pending the
feasibility of the sub-study with the African-American community, we will collect information
on eating-related behaviors in a large sample of individuals (N=350). If the initial
assessments (Phase1) prove that this is not a viable study to be conducted in that setting,
we will consider other population groups and other settings.
We are also considering Phase 3 activities if we identify clusters of eating-related
phenotypes within individuals. Amended IRB applications will be submitted prior to launching
Phase 3.

- INCLUSION
- For Phase 1 of the study, targets are family members attending African American family
reunions. Therefore, the eligibility to participate will be: age 18 or older; not
currently pregnant; attending the targeted family reunion.
- For Phase 2 of the study, the population for the study are adults (18 to 70
years-old), with the capability to read English. As this is a feasibility and
exploration study, the recruitment is intended to be broad and to include various
populations and profiles.
EXCLUSION
-Pregnant women will be excluded from participation in the study due to the focus on eating
behaviors and weight.
