In order to analyze the potential mediating effect of more information on partners (including perceived HIV status) on UAI, we developed three multivariable models. In version 1, we adapted the association 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 model 3, we adjusted also for venture 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 place for HIV-positive, HIV-negative and HIV status unknown MSM, an interaction between HIV status of the participant and dating place was included in all three models by making a fresh six-class variable. For clarity, the effects of online/offline dating on UAI are also presented separately for HIV-negative, HIV positive, and HIV-oblivious men. We performed a sensitivity analysis limited 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 miss potentially significant organizations. Backpage Escorts near me Chatfield. As a rather large number of statistical tests were done and reported, this approach does lead to a heightened danger of one or more false-positive organizations. Evaluations were done using the statistical programme STATA, version 13 (STATA Intercooled, College Station, TX, USA).
Features of on-line and offline partners and ventures 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 on-line ventures, perceived HIV concordance was higher (49.0% vs. 39.8%; P 0.001). Participants reported that their online partners more often understood the HIV status of the participant than offline partners (38.8% vs. 27.2%; P 0.001). Participants more often reported multiple sexual contacts with internet partners (50.9% vs. 41.3%; P 0.001). Sex-associated substance use, alcohol use, and group sex were less frequently reported with on-line partners.
In univariate analysis, UAI was significantly more inclined to happen in on-line than in offline partnerships (OR = 1.36 95 % CI 1.03-1.81) (Table 4 ). The self-perceived HIV status of the participant was firmly correlated with UAI (OR = 11.70 95 % CI 7.40-18.45). The result of dating location on UAI differed by HIV status, as can be seen best in Table 5 Table 5 shows the association of online dating using three distinct reference groups, one for each HIV status. Backpage Escorts Near Me Cherry Point Manitoba. Among HIV-positive guys, UAI was more common in online in comparison to offline partnerships (OR = 1.61 95 % CI 1.03-2.50). Among HIV negative guys no association was apparent between UAI and on-line partnerships (OR = 1.07 95 % CI 0.71-1.62). Chatfield backpage escorts. Among HIV-unaware men, UAI was more common in online in comparison to 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 variables concerning sexual behaviour in the venture (sex-related multiple drug use, sex frequency and partner kind), the independent effect of online dating place on UAI became somewhat more powerful (though not essential) for the HIV-positive guys (aOR = 1.62 95 % CI; 0.96-2.72), but remained similar for HIV negative guys (aOR = 0.94 95 % CI 0.59-1.48). The effect of online dating on UAI became stronger (and important) for HIV-oblivious men (aOR = 2.55 95 % CI 1.11-5.86) (Table 5 ).
The number of sex partners in the preceding 6months of the index was likewise connected 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 venture (OR = 16.29 95 % CI 7.07-37.52 for >10 sex acts within the partnership compared to just one sex act). Other factors significantly associated with UAI were group sex within the partnership, and sex-connected multiple drug use within partnership.
In this large study among MSM attending the STI clinic in Amsterdam, we found no signs that online dating was independently associated with a higher risk of UAI than offline dating. For HIV negative men this lack 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). Simply among guys who suggested they weren't conscious of their HIV status (a small group in this study), UAI was more common with on-line than offline partners.
Among HIV-positive guys, in univariate analysis UAI was reported significantly more frequently with online associates than with offline associates. When correcting for partner 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 factors between online and offline partnerships are in charge of the increased UAI in online established ventures. This might be because of a mediating effect of more info on associates, (including perceived HIV status) on UAI, or to other factors. Among HIV negative men no effect of online dating on UAI was discovered, either in univariate or in any of the multivariate models. Among HIV-oblivious guys, online dating was connected with UAI but just significant when adding associate and venture variables to the model.
An integral strength of the study was that it investigated the relation between online dating and UAI among MSM who had recent sexual contact with both online and also offline casual partners. This averted prejudice due to potential differences between men just dating online and those just dating offline, a weakness of several previous studies. Backpage Escorts Near Me Channing Manitoba. Backpage Escorts closest to Manitoba Canada. By recruiting participants at the largest STI outpatient clinic in the Netherlands we could include a great number of MSM, and avoid potential differences in guys sampled through Internet or face to face interviewing, weaknesses in a few previous studies 3 , 11
