Sexual identity and its relationship to injecting in a sample of disadvantaged young drug users

People who are new to injecting are at the highest risk of acquiring blood-borne viruses, and certain other characteristics, such as sexual identity, have been known to further heighten this risk. We investigate whether disadvantaged drug-using young people who are gay, lesbian, bisexual or who identify as other sexual identity (GLBO) are more likely to have ever injected drugs compared with their heterosexual peers.

Convenience sampling was employed across 15 youth services in metropolitan Sydney. Respondents were required to be 16-24 years of age, to have used an illicit drug, to have been exposed to injecting through social networks and been socially disadvantaged in the past 12 months. Participants self-completed a survey using touch screen laptops.

In a sample of 250 young people, GLBO participants more commonly reported ever injecting drugs [37.1%, confidence interval (CI) 21.5-55.1% vs. 12.3%, CI 8.1-17.4%] or injecting drugs in the past 12 months [31.4%, CI 16.9-49.3% vs. 5.7%, CI 2.9-9.6%] compared with participants who identified as heterosexual.

The higher rates of injecting among GLBO young people found in this sample advocates for the development of targeted prevention strategies for this group. Utilising existing networks in GLBO communities could be one strategy to limit the transition to injecting drug use and reduce the risk of drug-related harms among this group.
