Pill users may not be use condoms to protect against infections

The Brook Advisory Service has seen a 25% increase in the past two years and is concerned people under 18 are not looking after their sexual health.

The manager of Brook in Jersey, Bronia Lever, said many young people's knowledge of sexually transmitted infections was also patchy.

She said the increase in pill requests suggested they were not using condoms to help protect against infections.

Risk taking

She said: "Young people who are educated and do take time to find out about contraception and infection testing are less likely to take risks

"We really do need to be targeting people who are taking risks, and they tend to be the younger ones."

The service has now started to run a weekly clinic where anyone concerned about their sexual health can go to be tested and get advice.

The Brook Advisory Centre was set up on the island 10 years ago to give young people information on family planning.
