Published Research

  • HIV prevalence and risks associated with HIV infection among transgender individuals in Cambodia

    This survey of HIV prevalence and risk behaviors was conducted among transgender individuals in Cambodia. The data confirm that transgender individuals are one of the highest risk groups for HIV infection. For this group, the authors suggest the need for programmatic strategies that mitigate identified associated risks and facilitate access to HIV care.

  • Protocol of a cluster randomised stepped-wedge trial of behavioural interventions targeting amphetamine-type stimulant use and sexual risk among female entertainment and sex workers in Cambodia

    HIV risk among female entertainment and sex workers remains high, and use of amphetamine-type stimulants significantly increases this risk. The authors designed a cluster randomized stepped-wedge trial (Cambodia Integrated HIV and Drug Prevention Implementation (CIPI) study) to test sequentially delivered behavioral interventions targeting amphetamine use. The study is the first trial of an intervention to reduce amphetamine use and HIV risk among female entertainment and sex workers in Cambodia and will inform both conditional cash transfer plus aftercare in low- and middle-income countries and programs designed to reach this group.

  • Pharmacology, physiology and performance: Occupational drug use and HIV risk among female entertainment and sex workers in Cambodia

    The findings indicate that female entertainment sex workers in Cambodia use amphetamine-type stimulants to meet the physiological demands of sex work in a context of limited economic opportunities. Use of amphetamine-type stimulants has been associated with an increased risk of HIV and other sexually transmitted infections in key populations. In addition to health education, provisions are needed to both provide options for income generation that do not risk health and to better regulate safer working conditions.
