Depression in girls linked to greater time spent on social media
- Results of University College London study prompt concern about number of young women experiencing mental health problems

Girls’ much-higher rate of depression than boys is closely linked to the greater time they spend on social media, and online bullying and poor sleep are the main culprits for their low mood, new research reveals.
As many as three-quarters of 14-year-old girls who suffer from depression also have low self-esteem, are unhappy with how they look and sleep for seven hours or less each night, the study found.
“Girls, it seems, are struggling with these aspects of their lives more than boys, in some cases considerably so,” said Yvonne Kelly, from University College London, who led the team behind the findings.
The results prompted renewed concern about the rapidly accumulating evidence that many more girls and young women exhibit a range of mental health problems than boys and young men, and about the damage these can cause, including self-harm and suicidal thoughts.
The study is based on interviews with almost 11,000 14-year-olds taking part in the Millennium Cohort Study, a major research project into children’s lives.
