Clinical Brown Bag: Co-Occurrence of Food Addiction, High-Risk Substance Use, and Parental History of High-Risk Alcohol Use: Evidence for an Addictive-Like Eating Phenotype
Lindzey Hoover, Graduate Student, Clinical Science
Abstract:
An ongoing debate surrounds the existence of a phenotype for addiction to rewarding, highly processed (HP) food (commonly referred to as food addiction). The identification of shared risk factors for and high rates of co-occurrence between gambling and high-risk substance use was foundational to the recategorization of gambling as an addiction. Investigating shared risk factors such as family history of high-risk substance use and co-occurrence between food addiction and high-risk substance use may be an important area of research for informing whether this eating phenotype is consistent with an addictive model. In this study (n=357), we investigate rates of co-occurrence among food addiction, high-risk substance use (i.e., alcohol, cannabis, cigarettes, nicotine vaping), parental history of high-risk alcohol use, and obesity. Modified Poisson regression was used to calculate risk ratios unadjusted and adjusted for socio demographic covariates. Results of the current study indicated that risk of food addiction was higher in participants with high-risk alcohol use, cannabis use, smoking, vaping, and parental history of high-risk alcohol use. Obesity, in contrast, was not significantly associated with high-risk substance use and parental history of high-risk alcohol use indicating that food addiction and obesity are distinct phenotypes. Findings from this study support the conceptualization of food addiction as an addictive disorder and suggest that inclusion of food addiction as an addictive disorder in diagnostic frameworks is an important area for future consideration. This talk will include further discussion of conclusions from this study, including strengths and weaknesses of the current project, and future directions for work on this and related topics.
