A team has analysed data from a survey of more than 3,000 teenagers aged 11-19 in the UK. Their findings show that those with mental health problems spend an average of 50 minutes more per day on social media than those who do not suffer from them. According to the authors, who publish the results in the journal Nature Human Behaviour, further research is needed to know if this is a causal relationship.

A review of more than 100 meta-analyses and nearly 2500 studies has analysed the use of screens by children and young people and the consequences for their learning and health. Their conclusions are that, in general, the effects are small and vary according to the type of use and context. The results are published in the journal Nature Human Behaviour.
