Young people are at risk of sexually transmitted infections (STI), and engage in sex and drug related risk behaviour. This thesis investigates novel methods to reach youth for research and health promotion. Mobile phone text messages (SMS) are convenient, low cost, fast, and popular among youth. SMS has been utilised in sexual health for clinical management, service delivery and health promotion, but few of these projects have been evaluated. Recognising this lack of research led to the design of a randomised controlled trial investigating the use of SMS and email in sexual health promotion. Recruitment of young people for this trial was piloted at Melbourne’s Big Day Out. 939 young people were recruited in several hours; 30% were classified as being at high risk of STI, and 46% had used illicit drugs in the month prior to the survey. Knowledge of STI was poor. Drug use was associated with both sexual risk behaviour and music preference. The study demonstrated that this festival is a valuable site for sex and drugs research and health promotion. The following year, young people were recruited at the music festival and randomised to an intervention group who received regular sexual health SMS and email, or a control group who received no messages. After 12 months, the intervention group had higher STI knowledge than the control group (OR 2.72, 95%CI 1.68, 4.41) and intervention group females were more likely to have had an STI test (OR 2.51, 95%CI 1.11, 5.69). Respondents’ opinions of the messages were favourable. This simple, low-cost, and novel method was shown to be effective in improving young people’s sexual health. At-risk young people are not well represented in sex and drug behavioural surveillance in Australia. As the pilot study identified that a music festival was a suitable site for sex and drug research, the survey was repeated each year. Between 2005 and 2008, the proportion of young people at risk of STI decreased from 34% to 29%, and recent illicit drug use decreased from 46% to 43%. A limitation of the studies described herein is reliance on self-report, which is subject to recall bias; this can be reduced using diaries to collect behavioural data. Participants completed weekly diaries of sexual behaviour and a retrospective questionnaire. Correlation between the diaries and questionnaire was substantial, adding confidence to the validity of results of other studies in this thesis. Diaries can be collected in different ways; SMS has not previously been used for this purpose. Participants were randomised to complete diaries through SMS, online or paper. Online diaries were superior to SMS in completeness and participant preference, but SMS diaries were more likely to be submitted on time. This thesis has tested several novel options for researching and promoting health to young people. Through music festivals, SMS, and email, young people can be reached through settings and media they are familiar with. Use of these novel methods has increased understanding of risk behaviour among youth and been effective in sexual health promotion.
