## Abstract

PROJECT SUMMARY/ABSTRACT
Food insecurity is paradoxically associated with elevated risk of adolescent obesity in the United States. The
mechanisms underlying this excess risk are not well understood, and such knowledge is essential for informing
obesity prevention efforts for adolescents from under-resourced backgrounds. Thus, aligned with the need
emphasized by the Strategic Plan for NIH Obesity Research to identify the reasons contributing to increased risk
for obesity among economically marginalized populations, research is critically needed to elucidate modifiable
mechanisms to target in obesity prevention efforts among food-insecure adolescents. In the proposed project,
Dr. Hazzard, a registered dietitian and public health researcher, will examine binge eating as a potential
mechanism to explain the association between food insecurity and elevated risk for adolescent obesity. With the
exceptional mentorship team she has assembled and the resources available to her through the University of
Minnesota, this Pathway to Independence Award will support Dr. Hazzard in filling critical training gaps and
conducting the research necessary to launch her career as an independent investigator conducting intervention
work to promote food security and healthy weight among adolescents experiencing food insecurity. To prepare
her for this role, a multifaceted training plan including coursework, mentorship, and research is proposed in: (1)
qualitative and mixed methods, (2) advanced statistical methods, with a focus on machine learning and causal
mediation analysis, and (3) intervention design, development, and dissemination, with an emphasis on human-
centered design. The expertise Dr. Hazzard develops through this training plan will be essential for conducting
the proposed research. During the mentored K99 phase, she will elucidate the etiology of binge eating in the
context of food insecurity during adolescence using a mixed-methods approach that involves (a) conducting
qualitative interviews in food-insecure adolescents who report binge eating and (b) leveraging existing data from
an NIH-funded observational cohort to employ tree-based machine learning techniques (Aim 1). In the
independent R00 phase, Dr. Hazzard will recruit 175 adolescents into a new, independent cohort that she will
follow for 18 months to quantify the extent to which binge eating mediates the longitudinal association between
food insecurity and weight gain during adolescence (Aim 2). Finally, using a human-centered design approach,
she will develop vignettes describing potential school-based interventions to improve food security and prevent
excess weight gain among food-insecure adolescents and assess perceived acceptability of the potential
interventions using these vignettes in semi-structured interviews with adolescents who have experienced food
insecurity (Aim 3). Findings from this project will lay the groundwork for the development and implementation of
a school-based interven...
