Twice as many girls are unhappy with their appearance than boys, according to a new British study.

It finds 17% of girls aged 10 to 15 do not like how they look, compared to just 8% of boys that age.

Researchers think it has been made worse by the pressures of social media, like Facebook or Snapchat.

Although 68% of girls are still happy with their appearance, along with 79% of boys.

The Office for National Statistics (ONS) found that around 61% of children aged 11 to 15 talked to their mother about things that matter more than once a week in 2011-12, compared with 51% in 2002.

Similarly, 37% talked to their father frequently, compared with 31% in 2002.

Around 12% of children aged 10 to 15 in the UK reported being frequently bullied physically, in other ways, or both.

The study found that nearly all children - 98% - aged 10 to 15 used a computer at home.

While girls were more likely to use it to complete their homework, boys were more likely to play computer games.
