Love Island adverts and social media websites are putting "pressure" on young people over their body image, the head of the NHS has warned.

Simon Stevens, the chief executive of NHS England, raised concerns that cosmetic surgery adverts are being broadcast during breaks on the popular ITV2 show, in which attractive young contestants compete to win one another’s affections.

He also said Facebook and other social media websites are “in danger of ending up on the wrong side of history” by failing to protect young people.

Speaking on the BBC’s Andrew Marr show, Mr Stevens said it is not just the NHS’ job to tackle eating disorders and mental illness in young people, and that social media sites and television shows should take more responsibility.

“Take a show like Love Island,” Mr Stevens said. “Look at the adverts being shown alongside Love Island. You've got explicit ads being aimed at young women around breast cosmetic surgery. That is all playing into a set of pressures around body image that are showing up.”
