OBJECTIVE To carry out a randomised controlled trial on the effect of a new method of health promotion-email and mobile phone text messages (short messaging service (SMS))-on young people's sexual health. METHODS 994 people aged 16-29 were recruited at a music festival to a non-blinded randomised controlled trial. Participants were randomised to either(More)
Multiple factors affect injecting drug-related mortality, many of which will vary over time and between jurisdictions. There are relatively few studies of mortality among injecting drug users (IDU) in Australia. We aimed to provide data comparable to those reported internationally on the rate of mortality among IDU in Australia. We retrospectively examined(More)
BACKGROUND Chlamydia is most common among young people, but only a small proportion of Australian young people are tested annually. Home-based chlamydia testing has been piloted in several countries to increase testing rates, but uptake has been low. We aimed to identify predictors of uptake of home-based chlamydia testing to inform future testing programs.(More)
BACKGROUND Diaries are used in sexual behaviour research to reduce recall bias. Diary collection via mobile phone text messaging (SMS) has not been trialled previously in sexual behaviour research. This randomised controlled trial compared SMS, paper and online diaries on response rate, timeliness, completeness of data and acceptability. The correlation(More)
Hepatitis C virus (HCV) infection causes significant morbidity and mortality worldwide. T cells play a central role in HCV clearance; however, there is currently little understanding of whether the disease outcome in HCV infection is influenced by the choice of TCR repertoire. TCR repertoires used against two immunodominant HCV determinants--the highly(More)
OBJECTIVE To examine the reliability and validity of the Kessler 10 (K10) and the Patient Health Questionnaire (PHQ) in a sample of injecting drug users (IDUs). METHOD Participants were 103 IDUs with a current substance use disorder accessing a needle and syringe programme. Presence of mental health disorders was assessed using the Mini International(More)
BACKGROUND We aimed to measure the overlap between the social networks of injection drug users (IDUs) and the patterns of related hepatitis C virus (HCV) infections among IDUs. METHODS A cohort of 199 IDUs (138 of whom were HCV RNA positive) was recruited from a local drug scene in Melbourne, Australia, and was studied using social network analysis and(More)
Multiple genotypes of the hepatitis C virus (HCV) were detected in five of 138 HCV RNA positive injecting drug users (IDUs) recruited in Melbourne, Australia. Two were detected by combined LiPA and core and NS5a region sequencing, and three more (selected for testing due to their high-risk behaviour) by heteroduplex mobility analysis. We conclude that the(More)
BACKGROUND HIV continues to spread rapidly throughout Vietnam with injection drug use remaining the main risk factor for infection. The extent of pharmacy-based needle and syringe distribution has not previously been measured in Vietnam; this article reports on a pilot study exploring pharmacy-based harm reduction activities in Vietnam's capital, Hanoi.

INTRODUCTION AND AIMS Drug use is becoming normalised among young Australian people involved in music sub-cultures. We aimed to determine prevalences of illicit drug use in this population and associations between preferences for different music genres and recent use of particular illicit drugs. DESIGN AND METHODS A cross-sectional questionnaire of young(More)
