HIV-Related Risk Behaviors Among Japanese Tourists in the Khaosan Road Area, Bangkok, Thailand

This study investigated HIV-related drug use and sexual behaviors among Japanese tourists in the Khaosan Road area in Bangkok, Thailand. A stratified sample of 150 Japanese tourists anonymously self-administered a structured questionnaire. Approximately two thirds of participants had used illicit drugs. Among drug users, 33% and 49% had used marijuana during the past 6 months in Japan and in Thailand, respectively. Study participants tended to engage in riskier sex in Japan than in Thailand. In Thailand, 9% had not always used condoms with sex workers for vaginal sex. The majority of participants had engaged in sex with sex workers under the influence of alcohol in Japan (88%) and in Thailand (71%). Those who had engaged in high-risk sexual behaviors in Japan were more likely to engage in the same behaviors in Thailand, and vice-versa. Drug abuse and HIV/AIDS prevention programs targeting young Japanese tourists should be established in Thailand.
