The links between personality traits and risky behaviours

A new study has looked at the links between teenagers’ personality traits and risky behaviours like drink and drugs. Professor Ian Walker looks at the implications of what they discovered.

The prevalence of “risky” behaviours in terms of health and young people in the UK – drinking alcohol, taking drugs, unprotected sex – is higher than in other similar countries.

For example, British children aged between 16 and 24 years are likely to drink more than double the daily recommended amounts on their heaviest drinking day in the last week, and their frequent drug use is much higher than for older people. 

Abortion and sexually transmitted infections (STIs) rates peak in adolescence and 16 to 24-year-olds account for more than half of new STIs diagnosed in the UK.

It is obviously important for individuals and their health, but also for the UK as a whole. In 2006/07, smoking-related illness costs on the NHS were £3.3 billion, alcohol costs £3.3 billion, overweight and obesity costs £5.1 billion. In England and Wales in 2003/04, drug use was estimated to impose economic and social costs of £15.4 billion.
