take place at puberty. They should be taught how to manage <strong>the</strong>se in a positive way, in a context of <strong>the</strong><br />

importance of relationships, human reproduction, contraception, STIs, HIV and high-risk behaviours<br />

including early sexual activity. 184<br />

Evaluating <strong>the</strong> effectiveness of interventions in adolescent sexual health<br />

This section attempts to evaluate <strong>the</strong> effectiveness of several interventions in adolescent sexual health. To<br />

date, most sexual health interventions for adolescents have not been evaluated; consequently <strong>the</strong>re is not<br />

a great deal of reliable evidence regarding <strong>the</strong> effectiveness of different approaches. 185<br />

A recent review of international variations in teenage pregnancies shows that even those adolescents in <strong>the</strong><br />

most affluent areas of <strong>the</strong> <strong>UK</strong> have a higher birth rate than <strong>the</strong> average for <strong>the</strong> Ne<strong>the</strong>rlands or France.<br />

This, <strong>the</strong> authors suggest, leads to <strong>the</strong> possibility that teenage pregnancy is susceptible to policy<br />

interventions. 4<br />

Over <strong>the</strong> past four decades, fluctuations in <strong>the</strong> adolescent fertility rate seem to track<br />

intervention-related factors such as access to, and use of, contraceptive services, and <strong>the</strong> general climate<br />

surrounding <strong>the</strong> sexual health of young people. 156<br />

This also seems to demonstrate <strong>the</strong> potential of<br />

interventions in improving, or harming, adolescent sexual health.<br />

Education<br />

The <strong>UK</strong> has a poor record of sex education in comparison to some o<strong>the</strong>r European countries. 186<br />

However,<br />

school-based lessons are now, according to respondents in NATSAL, <strong>the</strong> main source of information about<br />

sexual matters for adolescents. 156<br />

School-based physical, health and social education can encourage<br />

behaviour modification in adolescents to help prevent unwanted pregnancy and <strong>the</strong> transmission of STIs.<br />

Education can focus on increasing awareness of STIs and birth control. It can also develop social skills,<br />

such as negotiating in relationships and accessing and using sexual health services. 160<br />

Some people recommend that sex education for adolescents should focus on abstinence. In <strong>the</strong> US,<br />

medical journals regularly publish articles encouraging healthcare professionals to recommend<br />

abstinence and giving detailed advice on how to do so most effectively. 187<br />

Abstinence-based educational<br />

approaches generally develop decision-making and refusal skills and rarely provide information on<br />

contraceptive methods or services. 173<br />

Reservations about abstinence-based education have been expressed<br />

by those who believe adolescents want practical information and help with sexual health ra<strong>the</strong>r than<br />

didactive approaches emphasising anatomical or moral aspects of sexual behaviour. 185<br />

One review of<br />

educational approaches to <strong>the</strong> prevention of teenage pregnancy found that, in comparison to usual sex<br />

education, abstinence programmes had no additional effect on ei<strong>the</strong>r delaying sexual activity or reducing<br />

pregnancy. 173<br />

Evaluative studies of educational strategies show that school-based sex education can be effective in<br />

reducing teenage pregnancy, especially when linked to access to contraceptive services. School-based skills<br />

building, combined with factual information and programmes encouraging vocational development, may<br />

also help to reduce rates of unwanted teenage pregnancy. The most reliable evidence shows that sex<br />

education does not increase sexual activity or pregnancy rates. 173<br />

Early intercourse and non-use of contraception is more common among adolescents whose main source<br />

of information about sex is not lessons at school. 156<br />

One analysis of NATSAL concluded that <strong>the</strong> association<br />

between school sex education and risk reduction provides grounds for optimism regarding <strong>the</strong> role of<br />

education in improving adolescents’ sexual health. 156<br />

Interviews with pregnant adolescents in inner <strong>London</strong> found that <strong>the</strong> major causes of unintended teenage<br />

pregnancy are failures to anticipate personal risk and error in <strong>the</strong> use of contraception. 188<br />

Successful school<br />

sex education needs to combine clear advice about contraceptive methods and how and when to access<br />

services, with educational techniques designed to help teenagers assess personal risk. 189<br />
