This study adds to evidence that substance use may lead to other risky behaviours such as casual sex. American researcher surveyed 483 incoming first-year college females several times over eight months and found that about 25% of them had at least one casual encounter during their first year of college. Whilst the strongest indicator that they would engage in casual relationships were pre-college 'hook ups', alcohol and marijuana use also increased this risk. Other factors included personality, behavioural intentions, situational triggers, family background, impulsivity and sensation-seeking. Interestingly, the authors found that race, socio-economic status, academics, cigarette smoking and 'parental connectedness' were not predictive indicators of sexual 'hook ups'. The study highlights the importance of prevention via health promotion and disease prevention programmes.
