Abstract:
An individual based randomized controlled trial (RCT) was designed to evaluate the impact of a customized short message service (SMS) intervention on HIV-related high-risk behaviors among Men who have sex with men (MSM). In total, 631 HIV-negative MSM were enrolled at baseline and divided into intervention and control groups randomly. Nine months later, the intervention group who received additional customized SMS intervention reported significantly lower rates of multiple partners, unclear partner infection status and condomless anal intercourse compared to the control group who received the routine intervention only. Six months post stopping the SMS intervention, the rates of unclear partner infection status and condomless anal intercourse still remained lower report in the intervention group. Our study shown that the customized SMS interventions can significantly reduce the HIV-related high-risk behaviors among MSM and with sustained effects over a period of time.
