title: The Relationship Between Methamphetamine Use, Sexual Sensation Seeking and Condomless Anal Intercourse Among Men Who Have Sex With Men in Vietnam: Results of a Community-Based, Cross-Sectional Study.
abstract: This study assessed the relationship between methamphetamine use and condomless anal intercourse (CAI) among men who have sex with men (MSM) in Hanoi and Ho Chi Minh City, Vietnam. Of 622 MSM participants, 75.7% reported any CAI in the last three months, 23.2% reported engaging in sex work in the last three months, 21.1% reported group sex in the last twelve months (21.1%) and 14.3% had used methamphetamine for sex in the last three months. CAI was associated with living in Ho Chi Minh City vs. Hanoi, being versatile during anal sex, a greater degree of sexual sensation-seeking, and more strongly agreeing that withdrawal before ejaculation is effective in preventing HIV. Effect-modification analysis showed that recent sex-related methamphetamine use was related to a higher probability of CAI for men with low sexual sensationseeking scores. Methamphetamine assessment and/or interventions should be incorporated into HIV prevention and research with Vietnam's MSM population.
