Why do record numbers of young people have sexually transmitted infections?

Hi everyone!
Today I going to talk about an article that I found very interesting It reflects a worldwide problem the name of this article is "Why do record numbers of young people have sexually transmitted infections?”
This article is on the website : http://www.guardian.co.uk/world/audio/2010/oct/15/focus-podcast-sexually-transmitted-infections-audio

Here Rosie Swash investigates the reasons for the UK's high level of sexually transmitted diseases among 15 to 24-year-old.
Based on the recent research published by the Health Protection Agency.
Women are particularly at risk, the figures showed.
Last year there were 482,696 new STI diagnoses - almost 12,000 more cases than in 2008.
In this week's Guardian Focus podcast Rosie Swash explores the reasons for this. She speaks to experts at sexual health charity Brook, Chris Bryant MP and teenagers themselves to find out why the numbers are so high and what needs to be done to get them down.
The lack of adequate sex education at school is often blamed, and Rosie visits her old school in north London to find out how they deal with this.
Many argue that parents exert a stronger influence over young people than schools. Young people tell Rosie about their experiences in broaching the subject with their mothers and fathers.
She explores the cultural reasons for the high numbers of STI's. Do we have double standards when dealing with sexually active girls?
In the end she opens a forum for young adults who want to express respect your opinion about
in my opinion I think these figures reflect a cultural change is a reality that young people increasingly earlier start their sexual life thus have a higher chance of getting an STI and if we add an inadequate sexual fitness is not about strange that these continue to rise.

In my opinion I think these figures reflect a cultural change is a reality that young people increasingly earlier start their sexual life thus have a higher chance of getting an STI and if we add an inadequate sexual practices is not about strange that these continue to rise, I believe that education begins at home is the family who has to put aside prejudices and see these issues as taboo subjects and parents should sit down with their children to explain the changes they experienced what it means sex diseases that are presented and the importance of caring as well not risk their health and that of the person you want.
