Problematic social media use and overweight/obesity: explanatory pathway analysis of 124 667 in-school adolescents in 39 high-income countries.

To the best of our knowledge, this is the first study that used nationally representative data from multiple countries in high-income countries to examine the association between PSMU and overweight/obesity and potential explanatory pathways among school-going adolescents. This finding has important implications for public health interventions to reduce overweight/obesity rates among young people.
