Prof Victoria Goodyear, Professor of Physical Activity, Health, and Wellbeing, University of Birmingham, said:
“In the study by Nagata and colleagues, data is reported from the ABCD study and of a large sample. The findings are consistent with existing evidence that reports increased time on social media is associated with worse outcomes, including the area of academic achievement. An interesting finding is that not only high, but lower levels of use are associated with worse outcomes. Appropriate limitations are reported.”
