For HIV-unaware guys the impact of dating place on UAI did not change by adding partner features, but it increased when adding lifestyle and drug use. It is hard to assess the actual risk for HIV for these men: do they behave as HIV-negative men that are trying to shield themselves from HIV infection, or as HIV-positive men attempting to guard their HIV-negative partner from HIV infection? A study by Horvath et al. Cheap Prostitutes closest to Queensland. reported that 72% of guys who were never tested for HIV, profiled themselves online as being HIV-negative, which might be problematic if they're HIV positive and engage in UAI with HIV-negative partners 12 Formerly Matser et al. reported that 1.7% of the oblivious and perceived HIV-negative MSM were examined HIV-positive. The study population included the MSM reported in this study 15
Online dating wasn't correlated with UAI among HIV negative guys, a finding in agreement with some previous studies, mainly among young men 21 , but in comparison with other studies 1 - 5 This may be because of the reality that most earlier studies compared sexual behaviour of two groups of MSM rather than comparing two sexual behavior patterns within one group of guys. Yet it might also reflect secular changes; perhaps in the beginning of online dating a more high risk group of men used the Internet, and over time online dating normalized and not as high-risk MSM today also utilize the Net for dating.
A key strength of this study was that it investigated the connection between online dating and UAI among MSM who had recent sexual contact with both online and offline casual partners. Cheap Prostitutes nearby QLD. This averted bias due to potential differences between guys just dating online and those simply dating offline, a weakness of several previous studies. By recruiting participants at the biggest STI outpatient clinic in the Netherlands we could contain a high number of MSM, and prevent potential differences in men sampled through Internet or face-to-face interviewing, weaknesses in a few previous studies 3 , 11
Among HIV-positive men, in univariate analysis UAI was reported significantly more frequently with on-line partners than with offline associates. When correcting for associate features, the effect of online/offline dating on UAI among HIV-positive MSM became somewhat smaller and became non-significant; this indicates that differences in partnership variables between online and also offline partnerships are in charge of the increased UAI in online established partnerships. This could be due to a mediating effect of more info on associates, (including perceived HIV status) on UAI, or to other variables. Among HIV-negative men no effect of online dating on UAI was observed, either in univariate or in some of the multivariate models. Among HIV-oblivious guys, online dating was associated with UAI but just significant when adding partner and venture variables to the model.
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 guys this dearth of assocation was clear (aOR = 0.94 95 % CI 0.59-1.48); among HIV positive men there was a nonsignificant association between online dating and UAI (aOR = 1.62 95 % CI 0.96-2.72). Aspley, Queensland Cheap Prostitutes. Simply among men who indicated they were not conscious of their HIV status (a little group in this study), UAI was more common with on-line than offline associates.
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 occurred in the partnership (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 venture, and sex-connected multiple drug use within partnership.
In multivariate model 3 (Tables 4 and 5 ), also including variants concerning sexual behaviour in the partnership (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 men (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 critical) for HIV-unaware guys (aOR = 2.55 95 % CI 1.11-5.86) (Table 5 ).
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 connected 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 different reference categories, one for each HIV status. Among HIV positive men, UAI was more common in online when compared with offline ventures (OR = 1.61 95 % CI 1.03-2.50). Among HIV negative guys no association was apparent between UAI and online partnerships (OR = 1.07 95 % CI 0.71-1.62). Among HIV-unaware men, UAI was more common in online compared to offline partnerships, though not statistically significant (OR = 1.65 95 % CI 0.79-3.44).
Features of on-line and offline partners and partnerships are revealed 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 on-line partners was more often reported as understood (61.4% vs. 49.4%; P 0.001), and in online partnerships, perceived HIV concordance was higher (49.0% vs. 39.8%; P 0.001). Participants reported that their on-line partners more frequently 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 online partners (50.9% vs. 41.3%; P 0.001). Sex-related substance use, alcohol use, and group sex were less frequently reported with internet partners.
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 version 1, we adapted the organization between online/offline dating location and UAI for characteristics 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 characteristics (age difference, ethnic concordance, lifestyle concordance, and HIV concordance). In model 3, we adjusted additionally for partnership sexual risk behavior (i.e., sex-related drug use and sex frequency) and venture type (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 individually for HIV-negative, HIV-positive, and HIV-unaware guys. Cheap Prostitutes closest to Aspley QLD. We performed a sensitivity analysis restricted 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. As a rather big number of statistical evaluations were done and reported, this strategy does lead to an elevated danger of one or more false positive associations. Investigations were done using the statistical programme STATA, version 13 (STATA Intercooled, College Station, TX, USA).
Prior to the evaluations we developed a directed acyclic graph (DAG) representing a causal model of UAI. In this model some variants were putative causes (self-reported HIV status; on-line partner acquisition), others were considered as confounders (participants' age, participants' ethnicity, and no. Aspley Queensland cheap prostitutes. Cheap Prostitutes Near Me Norman Park Queensland. of male sex partners in preceding 6months), and some were supposed to be on the causal pathway between the main exposure of interest and outcome (age difference between participant and partner; ethnic concordance; concordance in life styles; HIV concordance; venture sort; sex frequency within venture; group sex with partner; sex-related material use in venture).
We compared characteristics of participants by self-reported HIV status (using 2-evaluations for dichotomous and categorical variables and using rank sum test for continuous variables). We compared features of participants, partners, and venture sexual conduct by on-line or offline partnership, and calculated P values based on logistic regression with robust standard errors, accounting for related data. Continuous variables (i.e., age, amount of sex partners) are reported as medians with an interquartile range (IQR), and were categorised for inclusion in multivariate models. Random effects logistic regression models were used to analyze the association between dating place (online versus offline) and UAI. Odds ratio tests were used to assess the significance of a variable in a model.
To be able to investigate potential disclosure of HIV status we also asked the participant whether the casual sex partner knew the HIV status of the participant, with the answer alternatives: (1) no, (2) maybe, (3) yes. Sexual conduct with each partner was dichotomised as: (1) no anal intercourse or just shielded anal intercourse, and (2) unprotected anal intercourse. To discover the subculture, we asked whether the participant characterised himself or his partners as belonging to one or more of the following subcultures/lifestyles: casual, formal, alternate, drag, leather, military, sports, fashionable, punk/skinhead, rubber/lycra, gothic, bear, jeans, skater, or, if not one of these characteristics were related, other. Aspley QLD cheap prostitutes. Concordant lifestyle was categorised as: (1) concordant; (2) discordant. Casual partner kind was categorised by the participants into (1) known traceable and (2) anonymous partners.
HIV status of the participant was got by asking the question 'Do you know whether you are HIV infected?', with five response alternatives: (1) I 'm certainly not HIV-infected; (2) I think that I'm not HIV-contaminated; (3) I do not understand; (4) I believe I may be HIV-infected; (5) I know for sure that I am HIV-infected. We categorised this into HIV-negative (1,2), unknown (3), and HIV-positive (4,5) status. The survey enquired about the HIV status of each sex partner with all the question: 'Do you know whether this partner is HIV-contaminated?' with similar answer options as above. Perceived concordance in HIV status within partnerships was categorised as; (1) concordant; (2) discordant; (3) unknown. The last category represents all partnerships where the participant didn't know his own status, or the status of his partner, or both. In this study the HIV status of the participant is self-reported and self-perceived. The HIV status of the sexual partner is as perceived by the participant.
Participants completed a standardised anonymous survey during their visit to the STI outpatient clinic while waiting for preliminary test results after their consultation with a nurse or doctor. The survey elicited information on socio-demographics and HIV status of the participant, the three most recent partners in the preceding six months, and data on sexual behavior with those partners. A thorough description of the study design and also the questionnaire is provided elsewhere 15 , 18 Our main determinant of interest, dating location (e.g., the name of a pub, park, club, or the name of a site) was obtained for every partner, and categorised into online (websites), and offline (physical sites) dating places. To simplify the language of distinguishing the partners per dating place, we refer to them as online or offline partners.
We used data from a cross sectional study focusing on spread of STI via sexual networks 15 Between July 2008 and August 2009 MSM were recruited from the STI outpatient clinic of the Public Health Service of Amsterdam, the Netherlands. Men were eligible for participation if they reported sexual contact with men during the six months preceding the STI consultation, they were at least 18years old, and could understand written Dutch or English. People could participate more than once, if following visits to the clinic were related to a potential new STI episode. Participants were regularly screened for STI/HIV according to the standard procedures of the STI outpatient clinic 15 , 17 The study was accepted by the medical ethics committee of the Academic Medical Center of Amsterdam (MEC 07/181), and written informed consent was obtained from each participant. Included in this evaluation were men who reported sexual contact with at least one casual partner dated online as well one casual partner dated offline. Cheap Prostitutes Near Me Dakabin Queensland.
With increased familiarity in sexual partnerships, for example by concordant ethnicity, age, lifestyle, HIV status, and raising sex frequency, the likelihood for UAI increase as well 14 - 16 We compared the occurrence of UAI in online acquired casual partnerships to that in offline obtained casual partnerships among MSM who reported both online and offline casual partners in the preceding six months. Cheap prostitutes near Queensland. We hypothesised that MSM who date sex partners both online and offline, report more UAI with the casual partners they date on the internet, and that this effect is partly described through better understanding of partner characteristics, including HIV status.
