dc.description.abstractPrevious work focusing on the notion of food addiction has shown that in abundant amounts, highly-caloric- and hyper-palatable-foods can lead to addictive tendencies akin to drugs of abuse such as alcohol, nicotine, cocaine, opioids, and methamphetamine. However, such research is still in its infancy, with the notion of food addiction frequently being conflated with binge eating and obesity. The purpose of this study was to determine the unique variance accounted for in the symptom count and diagnosis of food addiction by various overeating patterns and behaviours most importantly binge eating and grazing after controlling for established physiological and psychological covariates. A total of 201 men and women between the ages of 20 and 50 years participated in the study. Subjects came from two cohorts: (1) York University undergraduate students, and (2) a dataset from Griffith University in Australia. Subjects of the first cohort were required to complete a self-report questionnaire booklet, and have their height and weight measured in person. Subjects of the second cohort were required to complete a self-report questionnaire online, and self-report their height and weight. A multiple regression analysis was employed using the symptom score of the Yale Food Addiction Scale. Results indicated that addictive personality traits, loss-of-control eating, reward-driven eating, and grazing each made a unique statistically significant contribution to the model. In the second stage of the analysis, a logistic regression analysis was employed using the binary diagnostic variable of the Yale Food Addiction Scale as the dependent variable. It was found that only loss-of-control eating significantly contributed to the model variance. The current findings provide novel insight into the association between a grazing pattern of overeating and food addiction, and emphasize that the Yale Food Addiction Scale symptom score and diagnosis should not be used interchangeably. Findings from this study add further support for the view that the intake of hyper-palatable foods can foster addictive-like consumption.
