Traits for the individuals. Traits associated with individuals, stratified by HIV status, are shown in dining Table 1.

Traits for the individuals, stratified by HIV status, are shown in dining dining Table 1. Almost all of men (60.8 percent) considered by themselves HIV-negative, 153 guys (26.5 percent) HIV-positive, and 73 (12.7 per cent) failed to understand their HIV status at period of enrolment. The entire age that is median 37 (IQR 30–43) years. HIV-positive guys were dramatically older and reported more lovers than HIV-negative or men that are HIV-unawareP Table 1 Characteristics of 577 males that have intercourse with males, stratified by milfplay dating self-perceived HIV status, Amsterdam, 2008-9

Online and offline partnership and partner traits

Traits of on the internet and offline lovers and partnerships are shown in dining dining Table 2. The age that is median of lovers had been 34 years (IQR 28–40). In comparison to offline lovers, more online partners were Dutch (61.3 per cent vs. 54.0 percent; P Table 2 traits of 1781 intimate lovers and partnerships of 577 males that have intercourse with males, in the shape of how a participant founded the partnership, Amsterdam, 2008-9

In extra file 1: Table S1 faculties of lovers and partnerships stratified by HIV status of participants are shown. UAI ended up being alot more typical in partnerships of HIV-positive guys (49 percent) than in partnerships of HIV-negative guys (13 percent) or HIV-unaware males (28 percent) (P dining dining Table 3 regularity of UAI by partner acquisition (online or offline) by participant’s and partner’s HIV status

Association between online/offline dating and UAI

In univariate analysis, UAI ended up being far more prone to occur in on the web than in offline partnerships (OR = 1.36 95 per cent CI 1.03–1.81) (Table 4). The HIV that is self-perceived for the participant ended up being highly related to UAI (OR = 11.70 95 per cent CI 7.40–18.45). The result of dating location on UAI differed by HIV status, because could be seen best in Table 5. Dining Table 5 shows the relationship of internet dating using three different guide categories, one for every HIV status. Among HIV-positive males, UAI ended up being more prevalent in online in comparison to offline partnerships (OR = 1.61 95 percent CI 1.03–2.50). No relationship had been obvious between UAI and online partnerships (OR = 1.07 95 per cent CI 0.71–1.62) among HIV-negative males. Among HIV-unaware males, UAI had been more widespread in online in comparison to offline partnerships, though perhaps perhaps not statistically significant (OR = 1.65 95 per cent CI 0.79–3.44).

In the 1st multivariate model (Tables 4 and 5), including only demographic and intimate behavior factors regarding the participant, the associations between online dating and UAI were nearly the same as those who work in the univariate model (aOR = 1.65 95 per cent CI 1.05–2.57 for HIV-positive guys, and aOR = 1.04 95 per cent CI 0.69–1.59 for HIV-negative guys, and aOR = 1.85 95 percent CI 0.86–3.98 for HIV-unaware males) ( dining Table 5).

In multivariate model 2 (Tables 4 and 5), variables regarding the partnership were added (life style concordance, cultural concordance, and HIV concordance). The effectation of fulfilling location on UAI had been smaller and no more significant (aOR = 1.43 95 per cent CI 0.89–2.31 among HIV-positive males dining Table 5).

In multivariate model 3 (Tables 4 and 5), also including variables concerning intimate behavior in the partnership (sex-related numerous medication usage, intercourse regularity and partner kind), the separate effectation of online dating sites location on UAI became notably more powerful (though maybe maybe not significant) for the HIV-positive guys (aOR = 1.62 95 per cent CI; 0.96–2.72), but stayed comparable for HIV-negative guys (aOR = 0.94 95 per cent CI 0.59–1.48). The consequence of internet dating on UAI became more powerful (and significant) for HIV-unaware guys (aOR = 2.55 95 percent CI 1.11–5.86) ( Dining Dining Dining Table 5).

Perceived concordance of HIV status had been related to UAI in models 2 and 3 (Table 4). In model 3, HIV discordance (aOR = 0.15 95 % CI 0.08–0.30) or HIV that is unknown (aOR = 0.25 95 percent CI 0.16–0.40) were adversely related to UAI (Table 4).

We investigated the consequence of self-perceived HIV concordance on UAI individually for HIV-positive and men that are HIV-negative. The consequence of self-perceived HIV concordance on UAI ended up being very good in HIV-positive males (aOR 24.09 95 per cent CI 9.17–63.31), not in HIV-negative males (aOR 0.42 95 percent CI 0.14–1.27).

The sheer number of intercourse lovers into the preceding half a year of this index has also been related to UAI (OR = 6.79 95 per cent CI 2.86–16.13 for those of you with 50 or higher sex that is recent in comparison to people that have less than 5 present sex lovers). UAI had been far more likely if more acts that are sex happened in the partnership (OR = 16.29 95 percent CI 7.07–37.52 for 10 intercourse functions in the partnership in comparison to only 1 intercourse work). Other facets considerably connected with UAI had been team intercourse in the partnership, and sex-related drug that is multiple within partnership.

I think I may be HIV positive” to the category Unknown, rather than to the category HIV-positive), the results were unchanged when we repeated the analyses using a different categorization of self-perceived HIV status (assigning those who indicated. A sensitiveness analysis, including only data of partnerships by which just one intercourse work had happened, showed results that are similar the association between online dating sites and UAI (data maybe perhaps maybe not shown).


In this study that is large MSM going to the STI center in Amsterdam, we discovered no evidence that online dating sites ended up being independently connected with a greater threat of UAI than offline dating. For HIV-negative males this not enough assocation had been clear (aOR = 0.94 95 per cent CI 0.59–1.48); among HIV-positive males there is a non-significant association between online dating sites and UAI (aOR = 1.62 95 percent CI 0.96–2.72). Just among guys whom suggested these people were perhaps perhaps perhaps not conscious of their HIV status (a group that is small this research), UAI ended up being more prevalent with online than offline lovers.

Among HIV-positive males, in univariate analysis UAI had been reported much more usually with online lovers than with offline lovers. Whenever adjusting for partner traits, the end result of online/offline dating on UAI among HIV-positive MSM became significantly smaller and became non-significant; this shows that variations in partnership facets between on the internet and offline partnerships have the effect of the increased UAI in online founded partnerships. This could be because of a mediating effectation of more info on lovers, (including recognized HIV status) on UAI, or even other facets. Among HIV-negative guys no effectation of online dating sites on UAI had been seen, in a choice of univariate or in any of the multivariate models. Among HIV-unaware males, internet dating ended up being related to UAI but just significant whenever incorporating partner and partnership factors to your model.

The information additionally declare that concordance in HIV status is a essential predictor for UAI in most teams (HIV- positive, -negative, and –unaware males). Concordance in HIV status may be much more very important to HIV-positive males compared to other people, as well as perhaps Web dating really helps to evaluate each other’s HIV status more effortlessly.

A vital energy for this study ended up being it explored the connection between internet dating and UAI among MSM that has current sexual experience of both online and offline casual lovers. This avoided bias brought on by possible differences when considering guys just dating online and those just dating offline, a weakness of a few past studies. By recruiting individuals during the biggest STI outpatient clinic in holland we could include a lot of MSM, and steer clear of possible variations in males sampled through online or interviewing that is face-to-face weaknesses in a few past studies 3, 11.
