Heterosexual men who patronise entertainment establishments versus brothels in an Asian urban setting - which group practises riskier sexual behaviours?

BACKGROUND: Sex work has shifted from brothels to entertainment establishments (EEs) in Asia. Men who patronise EEs could act as a bridging population for human immunodeficiency virus (HIV) and sexually transmitted infection (STI) transmission through unprotected sex with the female EE workers to their spouses and regular partners. The aim of this study was to compare the prevalence and factors associated with risky sexual behaviours among the heterosexual men who patronised the EEs and brothels in Singapore. METHODS: This was a cross-sectional survey involving 569 heterosexual men (297 recruited from brothels and 272 from EEs). A 2-stage sampling involving proportional stratified random sampling of the brothels and EEs, followed by time location sampling of the men, was conducted. For multivariable analysis, we used a mixed effects logistic model with backward elimination to account for clustering by venue and to obtain the adjusted odds ratio (aOR) for the association of various factors with consistent condom use in vaginal and oral sex respectively. RESULTS: Men who patronised EEs were younger, more likely to be single, more highly-educated and comprised more professionals compared to the brothel group. On multivariable analysis, consistent condom use for vaginal sex decreased at the EE setting (aOR 0.64; 95 % CI: 0.42 -0.97) and with alcohol use before sex (aOR 0.67; 95 % CI: 0.46 - 0.98) and increased with perceived high risk of getting HIV/STIs from partner (aOR 2.08; 95 % CI: 1.30 - 3.32) and partner's request for condom use (aOR 5.48; 95 % CI: 1.20 - 25.11). For consistent condom use with oral sex, this decreased at the EE setting (aOR 0.64; 95 % CI: 0.39 - 0.98) and with alcohol use before sex (aOR 0.50; 95 % CI: 0.31 - 0.81) and increased with partner's request for condom use (aOR 5.19; 95 % CI: 1.38 - 19.57). CONCLUSIONS: Men who patronised EEs practised risker sexual behaviours compared to the brothel group. Priority should be given for intervention programmes to target men who patronise EEs, which could involve the female EE workers, the EE owners as well as the managers for effective HIV/STI prevention.

Men seeking sex online practise riskier sexual behaviours than men frequenting brothels: survey findings from Singapore.

OBJECTIVE: To compare the prevalence of condom use and its associated factors within commercial and casual sex relationships between heterosexual men who seek sex online and those who frequent brothels in Singapore. METHODS: A survey was conducted between 2011 and 2012 among Singaporean heterosexual men aged 21-70 years who reported engaging in sexual intercourse with commercial or casual partners in the past year. Men seeking sex online (n=304) were recruited from the two most frequented local internet sex forums. Men frequenting brothels (n=297, 97% response rate) were recruited from a stratified cluster random sample of licensed brothels. RESULTS: Compared with men frequenting brothels, men seeking sex online reported significantly higher rates of oral and anal sex and sexually transmitted diseases but lower condom use for oral sex with commercial (16.5% vs 56.6%) and casual partners (21.2% vs 35.3%). In multivariate analyses, the online group showed that partner request for condom use was strongly associated with condom use for vaginal sex (adjusted ORs >3.0) but not with condom use for oral sex with both casual and commercial sex partners. The perceived risk of getting HIV from a partner was also associated with condom use for vaginal sex with commercial and casual partners; and for oral sex with casual partners. In contrast, condom use for oral and vaginal sex with both partners in the brothel group was only associated with partner request for condom use. CONCLUSIONS: Men seeking sex online should receive sexually transmitted infection (STI)/HIV prevention interventions that deal with the factors associated with condom use.

Human immunodeficiency virus (HIV) prevention education in Singapore: challenges for the future.

We reviewed the current human immunodeficiency virus (HIV) prevention education programmes in Singapore, discussed the challenges faced and proposed prevention education interventions for the future. Education programmes on HIV prevention have shown some success as seen by reduced visits to sex workers among the general adult population and a marked increase in condom use among brothel-based sex workers. However, we still face many challenges such as low awareness of HIV preventive strategies and high prevalence of HIV stigma in the general population. Voluntary HIV testing and condom use remain low among the priority groups such as men who have sex with men (MSM) and heterosexual men who buy sex. Casual sex has increased markedly from 1.1% in 1989 to 17.4% in 2007 among heterosexuals in Singapore, with the majority (84%) practising unprotected sex. Sex workers have moved from brothels to entertainment venues where sex work is mostly hidden with lack of access to sexually transmitted infections (STIs)/ HIV prevention education and treatment programmes. Education programmes promoting early voluntary testing is hampered because of poor access, high cost and stigma towards people living with HIV. It remains a challenge to promote abstinence and consistent condom use in casual and steady sexual relationships among heterosexuals and MSM. New ways to promote condom use by using a positive appeal about its pleasure enhancing effects rather than the traditional disease-oriented approach should be explored. Education programmes promoting early voluntary testing and acceptance of HIV-infected persons should be scaled up and integrated into the general preventive health services.
