Summary
Brief summary
Australia has rising numbers of sexually transmissible infections, high levels of unprotected sex among young adults & a high teenage abortion rate. To address these public health priorities, we will use mobile phone text messaging (aka SMS) & email to send sexual health & contraception information to young men & women. A randomised controlled trial of the impact of text & email messages on sexual risk-taking will enable rigorous analysis of their efficacy and cost-effectiveness, & provide valuable data about how these cheap technologies could be used on a larger scale.
