Abstract

Less data exist on HIV testing rates among male couples. By using dyadic data from 142 male couples, we found that less than a quarter of the men had been tested for HIV in the previous 3 months. Few factors also were associated with their most recent HIV test.

In 2008, the Centers for Disease Control and Prevention examined HIV testing histories among men who have sex with men (MSM) in 21 US cities. Among the MSM who had been tested for HIV, 19% tested HIV-positive; of these, 44% were unaware of their infection.1 Findings from this study indicate that expanding HIV testing efforts must include MSM and suggested reconsideration of whether sexually active MSM should test more often than once per year (i.e., every 3 months), regardless of their self-reported sexual behaviors.1 The Centers for Disease Control and Prevention currently recommends that gay, bisexual, and other MSM who have multiple or anonymous sex partners, who have sex while using drugs, or who have a partner who engages in these activities, be tested for HIV every 3 to 6 months.2 Recent estimates also indicate that 68% of MSM acquire HIV from their main sex partners.3 Because MSM remain disproportionately affected by HIV and a majority are contracting HIV in the context of a relationship, research has recently examined how relationship factors and sexual risk behaviors are contributing to these new infections.4,5 For example, previous research has explored relationship factors associated with unprotected anal intercourse (UAI), the primary sexual risk behavior for HIV acquisition, between main partners of male couples and among partnered men with a secondary male sex partner.4 Other studies have examined aspects of sexual agreements69; a sexual agreement is an explicit contract between main partners about which sexual behaviors may occur within the relationship and with any secondary sex partners. Nevertheless, limited data exist on the HIV testing rates of MSM in couples and which factors may be associated with their most recent HIV test.

The present study has 2 aims: (1) to report HIV testing rates among a convenience sample of male couples and (2) to examine which factors were associated with participants who reported having had an HIV test within the previous 3 months. We used a cross-sectional study design paired with a standard reciprocal dyadic data collection method to examine testing rates and factors associated with recent HIV testing (i.e., within previous 3 months) among both men in the male couple. A variety of recruitment methods were used to target and obtain a convenience sample of 142 male couples from Portland, Oregon and Seattle, WA, between June and November 2009. For example, business cards and flyers were distributed at gay-identified events and venues, referrals were made from local organizations that provided social services to gay men and other MSM, and electronic invitations were sent to profiles located on social websites frequented by gay men in the Pacific Northwest. A response rate was not recorded. Both members of each couple had to meet the following eligibility criteria to participate in the study: 18 years of age or older; self-identified as gay, bisexual, or queer; have had anal sex in the previous 3 months; had been coupled with his main partner for at least 3 months; and had an HIV-negative or unknown serostatus.

At a prearranged appointment, each qualified male in every couple read an electronic consent form and completed the 15- to 25-minute, self-administered, anonymous, electronic survey simultaneously, yet independently. Personal identifying information was not collected to decrease measurement error and participation bias.10 Data from 144 male couples were then screened for eligibility criteria and missing values and adjusted accordingly based on recommendations made by Acock.11 Data from 2 couples were deleted because of ineligibility and inconsistencies in responses.

The present study asked participants to complete a variety of measures in the electronic questionnaire, including common demographic information (age, race, highest education level achieved, etc.); relationship characteristics (i.e., type of relationship, having a sexual agreement); whether the men had UAI with their main partner and a secondary male sex partner in the previous 3 months; self-reports of, and perceived partner's, HIV serostatus and most recent HIV test; and validated measures for relationship factors of trust,12 relationship commitment,13 and investment in one's sexual agreement.14 Further details about the procedures and measures used in the present study have previously been reported.4,6

Dyadic data from 142 male couples were analyzed using Stata version 11 (StataCorp LP, College Station, TX). Responses to several questions were appropriately categorized, and descriptive statistics were calculated. Because we were most interested in factors associated with men's most recent HIV test, each participant's self-reported HIV test and his perceived main partner's last HIV test were dichotomized into 2 categories (i.e., <3 months vs. >3 months and never). Bivariate analyses compared men who got tested for HIV in the previous 3 months and men who did not or were never tested, by using the Pearson χ2 test, Fisher exact test, and the independent t-test as appropriate. Variables that differed significantly in bivariate analyses at P < 0.05 were then analyzed for multicollinearity in a pairwise deletion correlation matrix with Bonferroni correction. All predictors that were significant at P < 0.05 and had minimal issues of multicollinearity were included in the final multilevel random-intercept logistic regression model (i.e., xtlogit).

Recommendations from Kenny et al.15 were used to arrange the data into an appropriate format for random-intercept logistic regression, a multilevel modeling analytical technique used to calculate individual probabilities from dyadic data.16 In this case, data from both men in each couple were used to predict which factor(s) were associated with the likelihood (i.e., odds) that one or both of the men had been tested for HIV within the previous 3 months.

Recruitment site, relationship duration, and type of relationship were added as control variables to the final model. Odds ratios (ORs) and their associated 95% confidence intervals (CIs) were then calculated.

The average age of the men was 34.1 year (standard deviation, 8.4). Most men (N = 284) self-reported as gay (95%), HIV negative (95%), non-Hispanic (92%), white (85%), living in a city (82%), being employed (85%), earning more than $30,000 per year (79%), and/or having at least a bachelor's degree (68%). Most also perceived their main partner to be HIV-negative (93%), were living with their main partner (82%), and/or have been in their relationship for 2 years or longer (65%). Table 1 provides selected descriptive statistics of the sample's sexual risk behaviors, last HIV test, type of relationship, and couples' concordance about having a sexual agreement. Among those who reported having a sexual agreement, 77% reported that they explicitly discussed their agreement in detail with their main partner; 20% reported that they had definitively broken their agreement with their main partner. On average, the participants trusted their main partners, were invested in their relationship, and were invested in the sexual agreements that they had with their main partners.

Among the sample of male couples, several factors were significantly associated with one or both partners self-reporting that they had tested for HIV in the previous 3 months. The odds of testing for HIV in the previous 3 months were positively associated with both men in the couple (i.e., concordance) reporting that they had a sexual agreement (OR = 2.15 [95% CI, 1.10–4.21], P < 0.05), and with one or both men in the couple self-reporting that they had engaged in UAI with a secondary male sex partner within the previous 3 months (OR = 3.20 [95% CI, 1.22–8.43], P < 0.05). Furthermore, the odds of testing for HIV in the previous 3 months were negatively associated with men who indicated that they were living in Portland, Oregon (OR = 0.41 [95% CI, 0.21–0.79], P < 0.01). Results from the multilevel random-intercept logistic regression model analysis are presented in Table 2.

Findings from this study are the first to report HIV testing rates among male couples and the factors that are associated with recent HIV testing. Recent HIV testing rates in this study's sample were relatively low, even when controlling for differences in relationship types and UAI with the main partner in the multilevel random-intercept logistic regression model. Moreover, some men were never tested for HIV. Our results suggest that concurring with one's partner about having a sexual agreement may help encourage someone to test for HIV, perhaps as a component of the couple's sexual agreement. Some men may also have recently been tested for HIV as part of their HIV prevention strategy because they had engaged in a high-risk sexual behavior (i.e., UAI) with someone who was not their main partner. Given that the majority of MSM acquire HIV from their main sex partner while they are in a relationship, more research is urgently needed to determine what facilitators and barriers exist to HIV testing for male couples17 and whether testing is an active component to their sexual agreements.

This study is not without limitations, including the use of a cross-sectional study design and a convenience sample. Other limitations include the lack of data on other sexual risk behaviors besides UAI, the timing of when UAI had occurred with respect to HIV testing, reasons for obtaining an HIV test, whether HIV testing is a component to the sexual agreement, and the men's attitudes and perceptions of their risk for acquiring HIV. Despite these limitations, our study's main strength is the use of dyadic data with multilevel modeling analyses.

Future research with male couples should take these limitations into consideration when examining what factors may encourage or prevent male couples from HIV testing. Specifically, future studies are needed to examine how sexual agreements, HIV testing rates, and sexual behaviors are intertwined and how they affect the individual's and male couples' risk for HIV. Research that investigates the extent of male couples' communication about their sexual health, including testing, is also needed. These advances in research will help inform how best to develop and tailor future HIV prevention strategies for male couples.
