Social media addiction and daytime sleepiness as predictors of body dissatisfaction in Peruvian university students: A cross-sectional study

Introduction: currently, body dissatisfaction represents a growing concern among university population due to its impact on psychological and emotional well-being.Objective: to determine whether social media addiction and daytime sleepiness predict body dissatisfaction in university students from southern Peru.Methodology: a quantitative approach was used with a non-experimental predictive design. The sample consisted of 654 university students who completed the Social Media Addiction Questionnaire, the Epworth Sleepiness Scale, and the Body Shape Questionnaire (BSQ-14), instruments with adequate psychometric properties.Results: it was found that both social media addiction (β= 0.287, p<0.05) and daytime sleepiness (β= 0.174, p<0.05) have a significant predictive effect on body dissatisfaction in university students. Furthermore, the model adequately fit the data (F= 56.511, p<0.05) and explained 14.8% of the variability in body dissatisfaction (R²= 0.148), highlighting the relevance of these factors in understanding body image-related distress.Discussion: while some studies support these findings, further research is needed to confirm these results and analyze how social media addiction and daytime sleepiness interact with other psychological variables in shaping body dissatisfaction.Conclusions: Social media addiction and daytime sleepiness are significant predictors of body dissatisfaction in university students from southern Peru.
