A 10-year longitudinal study published in the Journal of the American Medical Association has found a significant correlation between heavy social media use and anxiety disorders in adolescents. Teenagers spending more than four hours daily on platforms such as TikTok, Instagram, and Snapchat showed 50 percent higher rates of clinical anxiety.
The study tracked 15,000 adolescents from ages 12 to 22, monitoring both social media habits and mental health indicators. Researchers controlled for pre-existing mental health conditions, socioeconomic factors, and family history to isolate the effect of social media use.
"The relationship is clear: more time on social media correlates with higher rates of anxiety, particularly among teenage girls," said lead author Dr. Sarah Twenge. "The effect is consistent across demographic groups and persists even after controlling for other risk factors."
The study found that the association was strongest for late-night social media use and passive consumption rather than active participation. "The comparison culture and disrupted sleep from late-night scrolling appear to be particularly harmful to adolescent mental health," Twenge explained.
Tech companies have disputed the findings, citing methodological limitations. "This study cannot establish causation, and we remain committed to providing tools that help users maintain healthy relationships with our platforms," said a Meta spokesperson.
