Traits of this individuals, stratified by HIV status, are shown in dining Table 1. Almost all of men (60.8 %) considered on their own HIV-negative, 153 males (26.5 percent) HIV-positive, and 73 (12.7 percent) failed to understand their HIV status at time of enrolment. The entire median age had been 37 (IQR 30–43) years. HIV-positive guys had been considerably older and reported more lovers than HIV-negative or HIV-unaware guys (P Table 1 Characteristics of 577 males who possess intercourse with males, stratified by self-perceived HIV status, Amsterdam, 2008-9

Traits of on the web and offline partners and partnerships are shown in dining Table 2. The age that is median of lovers was 34 years (IQR 28–40). In comparison to offline lovers, more partners that are online Dutch (61.3 per cent vs. 54.0 per cent; P Table 2 traits of 1781 intimate partners and partnerships of 577 males that have intercourse with guys, in the shape of the way the participant founded the partnership, Amsterdam, 2008-9
In Additional file 1: Table S1 faculties of lovers and partnerships stratified by HIV status of participants are shown. UAI ended up being way more typical in partnerships of HIV-positive guys (49 per cent) compared to partnerships of HIV-negative guys (13 per cent) or HIV-unaware males (28 percent) (P Table 3 regularity of UAI by partner purchase (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 a lot more prone to occur in on line than in offline partnerships (OR = 1.36 95 per cent CI 1.03–1.81) (Table 4). The HIV that is self-perceived of this participant had been highly related to UAI (OR = 11.70 95 per cent CI 7.40–18.45). The consequence of dating location on UAI differed by HIV status, since may be seen finest in Table 5. Dining dining dining Table 5 shows the relationship of internet dating using three various guide groups, one for every HIV status. Among HIV-positive males, UAI had been more widespread in online in comparison to offline partnerships (OR = 1.61 95 percent CI 1.03–2.50). Among HIV-negative males no relationship ended up being obvious between UAI and online partnerships (OR = 1.07 95 percent CI 0.71–1.62). Among HIV-unaware males, UAI had been more widespread in online in comparison to offline partnerships, though not statistically significant (OR = 1.65 95 percent 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 into 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 per cent CI 0.86–3.98 for HIV-unaware guys) ( dining dining dining Table 5).
In multivariate model 2 (Tables 4 and 5), variables regarding the partnership had been added (life style concordance, ethnic concordance, and HIV concordance). The aftereffect of fulfilling location on UAI ended up being smaller and no further significant (aOR = 1.43 95 percent CI 0.89–2.31 among HIV-positive men dining dining Table 5).
In multivariate model 3 (Tables 4 and 5), also including variables concerning intimate behavior in the partnership (sex-related numerous medication use, intercourse regularity and partner kind), the separate effectation of online dating sites location on UAI became significantly more powerful (though perhaps perhaps perhaps not significant) when it comes to HIV-positive males (aOR = 1.62 95 percent CI; 0.96–2.72), but stayed comparable for HIV-negative males (aOR = 0.94 95 percent CI 0.59–1.48). The consequence of online dating sites on UAI became more powerful (and significant) for HIV-unaware males (aOR = 2.55 95 percent CI 1.11–5.86) ( Dining Table 5).
Perceived concordance of HIV status ended up being connected with UAI in models 2 and 3 (Table 4). In model 3, HIV discordance (aOR = 0.15 95 percent CI 0.08–0.30) or HIV that is unknown (aOR = 0.25 95 per cent CI 0.16–0.40) had been adversely connected with UAI (Table 4).
We investigated the result of self-perceived HIV concordance on UAI individually for HIV-positive and men that are HIV-negative. The end result of self-perceived HIV concordance on UAI had been 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 per cent CI 0.14–1.27).
The amount of intercourse lovers when you look at the preceding six months for the index had been additionally related to UAI (OR = 6.79 95 per cent CI 2.86–16.13 for the people with 50 or even more sex that is recent in comparison to people that have less than 5 present intercourse lovers). UAI had been a lot more likely if more sex functions had happened in the partnership (OR = 16.29 95 per cent CI 7.07–37.52 for 10 intercourse functions inside the partnership in comparison to only 1 intercourse act). Other facets dramatically connected with UAI had been team intercourse in the partnership, and sex-related multiple medication usage 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 information of partnerships for which only 1 sex work had happened, revealed similar outcomes regarding the association between online dating sites and UAI (data perhaps perhaps not shown).
In this study that is large MSM going to the STI hospital in Amsterdam, we found no evidence that internet dating ended up being independently related to an increased danger of UAI than offline dating. This not enough assocation had been clear (aOR = 0.94 95 per cent CI 0.59–1.48) for HIV-negative males; among HIV-positive males there was clearly a non-significant relationship between online dating sites and UAI (aOR = 1.62 95 per cent CI 0.96–2.72). Just among guys whom suggested these people were perhaps maybe not alert to their HIV status (a group that is small this research), UAI had been more widespread with online than offline lovers.
Among HIV-positive guys, in univariate analysis UAI had been reported much more usually with online partners than with offline lovers. When adjusting for partner faculties, the end result of online/offline dating on UAI among HIV-positive MSM became notably smaller and became non-significant; this implies 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 an effect that is mediating of information about lovers, (including recognized HIV status) on UAI, or even to other facets. Among HIV-negative guys no effectation of online dating sites on UAI had been observed, in a choice of univariate or perhaps in some of the multivariate models. Among HIV-unaware males, online dating sites ended up being related to UAI but just significant whenever incorporating partner and partnership factors to the model.
The information additionally claim that concordance in HIV status is definitely a predictor that is important UAI in every 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, and maybe Web dating really helps to evaluate each HIV that is other’s more easily.
An integral power for this study was so it explored the connection between online dating sites and UAI among MSM that has current intimate experience of both online and offline casual lovers. This avoided bias brought on by potential differences when considering males just dating online and the ones just offline that is dating a weakness of a few previous studies. By recruiting individuals during the biggest STI outpatient center in holland we could add a lot of MSM, and steer clear of possible variations in guys sampled through online or face-to-face interviewing, weaknesses in certain past studies 3, 11.
