To be able to analyze the possible mediating effect of more info on partners (including perceived HIV status) on UAI, we developed three variant models. In model 1, we adapted the organization between online/offline dating place and UAI for features of the participant: age, ethnicity, number of sex partners in the preceding 6months, and self-perceived HIV status. In model 2 we added the partnership features (age difference, ethnic concordance, lifestyle concordance, and HIV concordance). In version 3, we adapted additionally for partnership sexual risk behavior (i.e., sex-associated drug use and sex frequency) and venture kind (i.e., casual or anonymous). As we assumed a differential effect of dating location for HIV positive, HIV negative and HIV status unknown MSM, an interaction between HIV status of the participant and dating location was contained in all three models by making a fresh six-class variable. For clarity, the effects of online/offline dating on UAI are also presented individually for HIV negative, HIV positive, and HIV-oblivious men. We performed a sensitivity analysis confined to partnerships in which only one sexual contact occurred. Statistical significance was defined as P 0.05. No adjustments for multiple comparisons were made, in order not to lose potentially important organizations. Backpage Escorts in Cranford. As a rather large number of statistical evaluations were done and reported, this strategy does lead to a higher risk of one or more false-positive organizations. Analyses were done using the statistical programme STATA, version 13 (STATA Intercooled, College Station, TX, USA).
Features of online and offline partners and partnerships are shown in Table 2 The median age of the partners was 34years (IQR 28-40). Compared to offline partners, more online partners were Dutch (61.3% vs. 54.0%; P 0.001) and were defined as a known partner (77.7% vs. 54.4%; P 0.001). The HIV status of online partners was more often reported as known (61.4% vs. 49.4%; P 0.001), and in online ventures, perceived HIV concordance was higher (49.0% vs. 39.8%; P 0.001). Participants reported that their online partners more often knew the HIV status of the participant than offline partners (38.8% vs. 27.2%; P 0.001). Participants more frequently reported multiple sexual contacts with online partners (50.9% vs. 41.3%; P 0.001). Sex-associated material use, alcohol use, and group sex were less frequently reported with online partners.
In univariate analysis, UAI was significantly more prone to occur in on-line than in offline ventures (OR = 1.36 95 % CI 1.03-1.81) (Table 4 ). The self-perceived HIV status of the participant was firmly associated with UAI (OR = 11.70 95 % CI 7.40-18.45). The effect of dating place on UAI differed by HIV status, as can be seen best in Table 5 Table 5 shows the organization of online dating using three different reference groups, one for each HIV status. Backpage Escorts Near Me Creekland Alberta. Among HIV positive men, UAI was more common in online in comparison to offline ventures (OR = 1.61 95 % CI 1.03-2.50). Among HIV-negative guys no association was apparent between UAI and internet ventures (OR = 1.07 95 % CI 0.71-1.62). Cranford Backpage Escorts. Among HIV-unaware guys, UAI was more common in online when compared with offline partnerships, though not statistically significant (OR = 1.65 95 % CI 0.79-3.44).
In multivariate model 3 (Tables 4 and 5 ), additionally including variants concerning sexual behaviour in the venture (sex-associated multiple drug use, sex frequency and partner kind), the independent effect of online dating place on UAI became somewhat more powerful (though not significant) for the HIV-positive guys (aOR = 1.62 95 % CI; 0.96-2.72), but remained similar for HIV-negative men (aOR = 0.94 95 % CI 0.59-1.48). The result of online dating on UAI became stronger (and significant) for HIV-unaware guys (aOR = 2.55 95 % CI 1.11-5.86) (Table 5 ).
The amount of sex partners in the preceding 6months of the index was likewise associated with UAI (OR = 6.79 95 % CI 2.86-16.13 for those with 50 or more recent sex partners compared to those with fewer than 5 recent sex partners). UAI was significantly more likely if more sex acts had happened in the partnership (OR = 16.29 95 % CI 7.07-37.52 for >10 sex acts within the partnership compared to only one sex act). Other factors significantly associated with UAI were group sex within the venture, and sex-connected multiple drug use within venture.
In this large study among MSM attending the STI clinic in Amsterdam, we found no evidence that online dating was independently associated with a higher risk of UAI than offline dating. For HIV negative men this dearth of assocation was clear (aOR = 0.94 95 % CI 0.59-1.48); among HIV-positive guys there was a non significant association between online dating and UAI (aOR = 1.62 95 % CI 0.96-2.72). Just among men who suggested they weren't conscious of their HIV status (a little group in this study), UAI was more common with online than offline associates.
Among HIV positive men, in univariate analysis UAI was reported significantly more often with online associates than with offline partners. When adjusting for associate features, the effect of online/offline dating on UAI among HIV positive MSM became somewhat smaller and became nonsignificant; this indicates that differences in partnership variables between online and also offline partnerships are accountable for the increased UAI in online established ventures. This could be because of a mediating effect of more info on associates, (including perceived HIV status) on UAI, or to other variables. Among HIV negative guys no effect of online dating on UAI was discovered, either in univariate or in the multivariate models. Among HIV-unaware men, online dating was correlated with UAI but only critical when adding partner and partnership variables to the model.
An integral strength of this study was that it explored the relationship between online dating and UAI among MSM who had recent sexual contact with both online and offline casual partners. This avoided prejudice caused by potential differences between men just dating online and those only dating offline, a weakness of numerous previous studies. Backpage Escorts Near Me Crammond Alberta. Backpage escorts near me Alberta, Canada. By recruiting participants at the biggest STI outpatient clinic in the Netherlands we could comprise a high number of MSM, and avoid potential differences in men sampled through Internet or face to face interviewing, weaknesses in a few previous studies 3 , 11
