The impact of social media use on body image and disordered eating behaviors: Content matters more than duration of exposure.

Social media use is rapidly expanding in terms of frequency, duration, and the diversity of platforms available. Given evidence for associations between social media use, body image disturbances, and disordered eating it is important to identify potentially harmful aspects of social media use that could serve as intervention targets. This study surveyed two demographically diverse undergraduate student cohorts in 2015 and 2022 to compare patterns in social media use, body image, and disordered eating behaviors between samples, including as a function of the COVID-19 pandemic, and to test the hypothesized moderating role of specific content consumed in the association between social media use and maladaptive outcomes. Participants in 2022 reported greater body image disturbances, more frequent vomiting and laxative use, and more time spent on a greater number of social media accounts, with significantly greater use of image-based platforms such as Snapchat, TikTok, and YouTube. Moderated regression analyses suggest that type of content consumed, but not the amount of time spent on social media or diversity of platforms utilized, is associated with body image disturbances and disordered eating behaviors after controlling for gender and body mass index. Specifically, exposure to weight loss content was associated with lower body appreciation, greater fears of negative appearance evaluation, and more frequent binge eating. Contrary to initial hypotheses, exposure to body positivity/neutrality content did not have protective effects. Findings suggest that interventions targeting negative consequences of social media use should focus on addressing content consumed, rather than time spent on social media platforms.

Eating disorder pathology and compulsive exercise during the COVID-19 public health emergency: Examining risk associated with COVID-19 anxiety and intolerance of uncertainty.

OBJECTIVE: COVID-19 has led to disruptions in daily living and increased uncertainty about physical, financial, social, and psychological consequences, which may contribute to anxiety, eating disorder (ED) pathology, and compulsive exercise. Individual factors, such as intolerance of uncertainty, may impact risk for ED pathology and CE in response to COVID-19 anxiety. The current study examined associations between COVID-19 anxiety, trait intolerance of uncertainty, and COVID-19 intolerance of uncertainty and ED pathology and compulsive exercise. METHOD: Undergraduate participants (N = 295) completed a series of online questionnaires between March and April of 2020. RESULTS: COVID-19 anxiety and intolerance of uncertainty were associated with ED pathology, but not compulsive exercise. Additionally, both trait and COVID-19 intolerance of uncertainty moderated associations between COVID-19 anxiety and compulsive exercise and ED pathology. COVID-19 anxiety was more strongly related to compulsive exercise and ED pathology for individuals with lower intolerance of uncertainty. DISCUSSION: COVID-19 anxiety may increase risk for ED pathology and may be specifically important in determining risk for ED pathology and compulsive exercise among individuals with lower intolerance of uncertainty. These results contribute to a growing body of research aimed at understanding the mental health consequences of the COVID-19 and suggest that individual factors (e.g., anxiety and intolerance of uncertainty) are important in determining risk for ED pathology and compulsive exercise in the context of the pandemic.
