Brief Summary

The current pilot study will examine emergent hypotheses by investigating the role of psychological mechanisms in the relationship between food insecurity and obesity. This objective will be achieved via a cross-sectional, observational pilot study collecting quantitative and qualitative data.

Detailed Description

This pilot study will investigate an emergent risk factor for obesity: food insecurity, which is defined as the limited or uncertain availability of nutritionally adequate and safe foods. While paradoxically linked, numerous studies have shown a significant association between food insecurity and obesity. Moreover, recent narrative works have developed new, untested hypotheses linking food insecurity and obesity positing the causal role of psychological mechanisms. Given this, this mixed method pilot study will collect new psychological data in a sample of food secure and food insecure adults with and without obesity to examine the connections between food insecurity, body weight, and psychological constructs. The overarching objective of the study is to gather pilot data to identify potentially new intervention targets that will be used in future studies to more rigorously investigate the relationship between food insecurity and obesity.
