Social Influence on Fad Diet Use: A Systematic Literature Review

Background: A fad diet is a broad term used to describe dieting methods that recommend altering the intake of macronutrients to specific proportions or instruct people to intake or avoid particular foods, often with the goal of rapid weight loss. Previous literature reviews report social influence impacts general diet behaviour, but have yet to examine fad diets, specifically. Therefore, the purpose of this systematic review was to synthesize literature related to social influence on an individual's fad diet use and understand the sociocultural factors related to diet use. Methods: Using PRISMA guidelines, Medline, PsycInfo, Embase, CINAHL, and CENTRAL databases were searched to identify articles investigating the impact of social on fad diet use. Covidence was used to manage the review process and Garrard's Matrix Method was used to extract data from reviewed articles (n   =   13). Results: A majority of reviewed studies examined interpersonal influence (62%) and reported social influence impacting a variety of fad diet behaviours (92%). Interpersonal and media influence were highlighted as motivating factors for adopting unhealthy dieting methods (54%), and studies showed interpersonal support impacted adoption and maintenance of fad diet use (23%). Also, social norms were reported to influence unhealthy weight control behaviours (15%). Discussion: This review revealed social influence is associated with the adoption, adherence, and termination of fad diets. The prevalence of fad diets in society and the lack of research on this topic warrants further examination of factors related to fad diets use and the spread among interpersonal networks.

Predicting emotional abuse among a sample of college students

Objective This study aims to examine factors related to emotional abuse, an understudied type of intimate partner violence (IPV), among a sample of college students. Participants: 601 undergraduates from one large public university in the Midwestern United States (Spring 2017) and 756 undergraduates from one large public university in the Southern United States (Fall 2019) participated in the study. Methods: Participants completed an online survey measuring demographic information, behavioral variables (viewing porn, alcohol consumption, and hooking up), and history of violence (witnessing a father abuse his spouse, emotional abuse history). Descriptive statistics and binary logistic regression analyses predicting emotional abuse victimization were conducted. Results: Results indicate female, white, older students were more likely to report emotional abuse. Also, students witnessing their father abuse his spouse, frequent pornography use, increased alcohol use, and frequent hookups increased odds of emotional abuse. Conclusion: College campuses should consider emphasizing emotional abuse in IPV programing.
