Few studies have examined the association between methamphetamine (MA) abuse and sexually transmitted infection (STI) risk among heterosexual male MA users in China. A total of 288 heterosexual male MA users who met our inclusion criteria were recruited from nightclubs, KTVs, bars, bath centres and an STI clinic. STIs were screened among the participants, and the risk factors related to STIs were analysed by multivariate logistic regression in SPSS 11.0. Among the 288 heterosexual male MA users, 51 (17.7%) had syphilis, 36 (12.5%) had genital warts, 2 (0.7%) had genital herpes, 3 (1.0%) had HIV infection and 41 (14.2%) had urethritis. STIs were associated with the following variates: ‘MA has the function of anti-inebriation’ (OR = 2.522, 95%CI = 1.337–4.756), ‘I am addicted to MA’ (OR = 4.030, 95%CI = 2.194–7.401), ‘It occurred to me to abstain from MA’ (OR = 2.939, 95%CI = 1.246–6.934), ‘Years of MA abuse’ (OR = 2.622, 95%CI = 1.318–5.215), ‘Times of MA abuse per week’ (OR = 5.275, 95%CI = 1.988–14.002), ‘Number of persons using MA together’ (OR = 2.579, 95%CI = 1.246–5.340) and ‘Number of female sex workers as sex partners per MA abuse’ (OR = 4.004, 95%CI = 1.526–10.508). Our findings show that MA users belong to the high-risk group for STI in China. STIs, except for HIV, have spread widely among heterosexual male MA users. Thus, specific interventions must be conducted to prevent the spread of STIs in this population in China.
