ATS Study

Tue 27 Feb 2018 Clinical Research

Title: Amphetamine-type stimulants and its relationship with HIV incidence and antiretroviral adherence among Thai men who have sex with men and transgender women (MSM and TG).
Status: Ongoing

What is ATS?
ATS is a study being done to evaluate the pattern of amphetamine-type use (ATS) by HIV status and the associated demographic and behavioral risk characteristics. The effect of ATS use on HIV and STI incidence among HIV-negative and antiretroviral adherence and virologic suppression among HIV- positive men who have sex with men and transgender women (MSM and TG) will also be studied. Who is participating in ATS study? ATS will enroll approximately 510 HIV-infected and uninfected MSM and TGW, ages 18 and older. The participants will be enrolled for 18 months, with the total of 4 follow-up visits.

Why is ATS important?
The use of ATS has become increasingly common among MSM globally. Among HIV-negatives, ATS use has been shown to be correlated with unsafe sexual risk behavior and the acquisition of STI and HIV. Among HIV-positives, ATS use is associated with dramatically poorer ART adherence and increased risk for ART drug-resistance. However, data on ATS use among Thai MSM and TG is very limited. The study hopes to better understand the dynamics of ATS use and the relationship with HIV incidence and ART adherence, which will be crucial in designing behavioral and biomedical interventions for HIV prevention and care programs.
