ABSTRACT

The importance of the acceptability of rectal microbicides for HIV and sexually transmissible infections (STIs) prevention is widely recognised. Given relatively consistent use of lubricants for anal intercourse (AI) and the potential for lubricant-like rectal microbicides, understanding barriers to lubricant use may help inform hurdles likely to be encountered once a rectal microbicide becomes available.
We conducted an internet-based survey using a 25-item questionnaire to assess AI and lubricant use, including lubricant preferences and barriers to use.
The majority of the 6124 respondents who reported AI were male (93%), 25 years or older (80%) and from North America (70%). Consistent condom use during AI was reported by a minority (35%) and consistent lubricant use was reported by over half of respondents. Reasons for non-use differed by age and region. Among men, those <25 years were more likely to report barriers around cost compared with those 45 and older (odds ratio (OR) = 6.64; 95% confidence interval (CI) 3.14-14.03). European men (OR = 1.92; 95% CI 1.50-2.45), Latin American women (OR = 3.69; 95% CI 1.27-10.75) and Asian women (OR = 4.04; 95% CI 1.39-11.78) were more likely to report sexual preference as a reason for non-use.
Rectal lubricants are widely used, but barriers to use vary by age and region for dry sex. A lubricant-like rectal microbicide would potentially be acceptable and such a product may be useful as a method of HIV prevention. However, targeted marketing and educational approaches may be needed to enhance use and acceptability of such a product.

    • "Phase II trials are now underway to assess the safety, acceptability, and pharmacodynamics of various rectal microbicide gel formulations (McGowan, 2014). To facilitate the uptake of effective rectal microbicide gels, previous studies have investigated the frequency of lubricant use, product preferences, and barriers to lubricant use among those who practice AI (Carballo-Dieguez, O'Sullivan, et al., 2007; Carballo-Dieguez et al., 2000; Javanbakht, Murphy, Gorbach, LeBlanc, & Pickett, 2010). However, additional data on the dynamics of commercial lubricant use at the sexual event-level among MSM are needed to inform the development of rectal microbicide gels acceptable for use during AI.

    ABSTRACT: To inform the development and assess potential use of rectal microbicide gels for HIV prevention among men who have sex with men (MSM), we examined the dynamics and contexts of commercial lubricant use during receptive anal intercourse (RAI) within this population. From 2007 to 2010, 168 HIV-negative MSM living in Los Angeles who practice RAI completed computer-assisted self-interviews, which collected information on their last sexual event with ≤3 recent partners, at baseline, three months, and one-year study visits. Logistic generalized linear mixed models were used to identify individual- and sexual event-level characteristics associated with commercial lubricant use during RAI at the last sexual event within 421 partnerships reported by participants over the course of follow-up. During RAI at their last sexual event, 57% of partnerships used a condom and 69% used commercial lubricant. Among partnerships that used commercial lubricant, 56% reported lubricant application by both members of the partnership, 66% first applied lubricant during sex, but before penetration, and 98% applied lubricant at multiple locations. The relationship between substance use and commercial lubricant use varied by condom use (interaction p-value = 0.01). Substance use was positively associated with commercial lubricant use within partnerships that used condoms during RAI at their last sexual event (adjusted odds ratio [AOR] = 4.47, 95% confidence interval [CI]: 1.63-12.28), but no association was observed within partnerships that did not use condoms (AOR = 0.66, 95% CI: 0.23-1.85). Commercial lubricant use during RAI was also positively associated with reporting more sexual partners (AOR = 1.18, 95% CI: 1.05-1.31), while older age (units = 5 years; AOR = 0.75, 95% CI: 0.61-0.94), homelessness (past year; AOR = 0.32, 95% CI: 0.13-0.76), and having sex with an older (>10 years) partner (AOR = 0.37, 95% CI: 0.14-0.95) were negatively associated with commercial lubricant use. These factors should be considered in the development of rectal microbicide gels to enhance their acceptability and use among MSM.

    • "Our finding that douching varied by region is supported by the small number of rectal douching prevalence studies [18,22,23] as well as other studies on rectal practices surrounding AI such as lubricant use [30] and may reflect variations in sexual practices by region. Indeed, in exploring reasons for lack of rectal douching by region we found that in regions where the prevalence of rectal douching was low such as Asia, reporting that ‘Didn’t know people used an enema or douche for anal intercourse’ was far more common than regions where rectal douching was high (53% in Asia vs. 17% in North America, p value < .01; data not shown).

    ABSTRACT: Rectal products used with anal intercourse (AI) may facilitate transmission of STIs/HIV. However, there is limited data on rectal douching behavior in populations practicing AI. We examined the content, types of products, rectal douching practices and risk behaviors among those reporting AI. From August 2011 to May 2012, 1,725 women and men reporting receptive AI in the past 3 months completed an internet-based survey on rectal douching practices. The survey was available in English, French, German, Mandarin, Portuguese, Russian, Spanish, and Thai and included questions on sexual behaviors associated with AI including rectal douching. Differences by rectal douching practices were evaluated using chi-square methods and associations between reported douching practices and other factors including age and reported STI history were evaluated using logistic regression analysis. Respondents represented 112 countries, were mostly male (88%), and from North America (55%) or Europe (22%). Among the 1,339 respondents (66%) who reported rectal douching, most (83%) reported always/almost always douching before receptive AI. The majority of rectal douchers reported using non-commercial/homemade products (93%), with water being the most commonly used product (82%). Commercial products were used by 31%, with the most common product being saline-based (56%). Rectal douching varied by demographic and risk behaviors. The prevalence of rectal douching was higher among men (70% vs. 32%; p-value < .01), those reporting substance-use with sex (74% vs. 46%; p-value < .01), and those reporting an STI in the past year (69% vs. 57% p-value < .01) or ever testing HIV-positive (72% vs. 53%; p-value < .01). In multivariable analysis, adjusting for age, gender, region, condom and lubricant use, substance use, and HIV-status, douchers had a 74% increased odds of reporting STI in the past year as compared to non-douchers [adjusted odds ratio (AOR) = 1.74; 95% CI 1.01-3.00]. Given that rectal douching before receptive AI is common and because rectal douching was associated with other sexual risk behaviors the contribution of this practice to the transmission and acquisition of STIs including HIV may be important.
