A cross-sectional investigation of the factors associated with awareness of PEP and PrEP among Queensland university students

Abstract

Abstract Objective: University creates unique social environments for many young people that can result in behaviour changes that can impact sexual health-related risks and facilitate transmission of HIV. Little is known about HIV knowledge, risk, and awareness of pre-exposure prophylaxis/ post-exposure prophylaxis (PrEP/PEP) among Australian university students. Methods: A 2019 online survey distributed through Queensland universities, using active recruitment/snowball sampling. Descriptive and logistical regression analysis investigated HIV knowledge/risk and PrEP/PEP awareness. Results: Of the 4,291 responses, 60.4% were 20–29 years old, 57.0% identified as heterosexual, and 31.8% were born-overseas. Mean HIV knowledge score was 9.8/12. HIV risk scores were higher among men-who-have-sex-with-men (MSM) (mean=5.2/40) compared to all other sexual behaviours (mean=3.1/40). Logistic regression indicated PrEP and PEP awareness was associated with older age (p<0.05), being nonbinary/gender-diverse (p<0.05), and MSM (p<0.05). Lower odds of PrEP awareness were associated with international student status (p<0.05). Conclusion: This study highlights the need for future health promotion targeting younger Australians at risk of HIV to increase uptake of PrEP/ PEP, particularly among overseas-born young people and those ineligible for appropriate health care in Australia. Implications for public health: Addressing these gaps will improve sexual health outcomes for young Australians at risk of HIV and work towards virtual elimination of HIV transmission in Australia. Key words: HIV, PrEP, PEP, university students, men who have sex with men, international students
