As screens are increasingly integrated into every facet of modern life, there is growing concern over the potential effects of high screen time. Previous studies have largely utilized self-report data on mood and behavioral aspects of screen time. In this study, we explored the fecal microbiome and metabolome of a diverse group of 60 college students, classified by high (≥ 75 min/day) or low (0-75 min/day) self-reported screen time using 16S rRNA amplicon sequencing, targeted liquid chromatography-tandem mass spectrometry, and targeted short-chain fatty acid detection using gas chromatography-mass spectrometry. Several key taxa and metabolites were significantly altered between groups and found to be highly co-occurrent. Pathway and enzyme enrichment analyses indicated widespread dysfunction of amino acid metabolism. High screen time was also predicted to be associated with type I diabetes, obesity, chronic fatigue syndrome, and various manifestations of inflammatory bowel. These results provide a data-driven hypothesis for future experimental research.
