The Relationship Between SNS Usage and Disordered Eating Behaviors: A Meta-Analysis

Area of Science:

• Psychology and Behavioral Science
• Public Health
• Digital Media Studies

Background:

• Social Networking Sites (SNSs) are prevalent in modern life, facilitating social connections but also raising concerns about potential negative health impacts.
• Existing research presents conflicting findings regarding the association between SNS use and eating disorders.
• A comprehensive synthesis is needed to clarify the relationship between SNS engagement and disordered eating behaviors.

Approach:

• A systematic meta-analysis was conducted, synthesizing data from 22 studies comprising 87 effect sizes.
• A three-level random-effects meta-analysis model was employed to analyze the data.
• Potential moderators, including body mass index, survey methodology, and sample demographics, were examined.

Key Points:

• A significant positive correlation was found between SNS use and irregular eating behaviors (r = 0.09).
• The association was stronger when data was collected via paper-and-pencil surveys compared to online surveys.
• University students exhibited a higher correlation between SNS use and disordered eating behaviors.

Conclusions:

• Excessive use of Social Networking Sites is associated with an increased risk of disordered eating.
• Survey methodology and sample characteristics, particularly in university populations, significantly influence the observed relationship.
• Findings provide a basis for future interventions and management strategies concerning social media and dietary habits.
