Sex workers have their perspective on HIV transmission, claiming that in general they are more similar than different from other people in HIV status and the practice of safe sex. Such an assertion of similarity goes against public and professional opinion that prostitution is a major vector in the spread of AIDS. Taking the sex workers' similarity claim seriously, this paper considers the conditions under which it would be valid. We focus on those factors that make a population more or less vulnerable to HIV and how they affect its spread into the sex work population. Data from New Zealand comparing men sex workers and other men who have sex with men is used to evaluate these ideas. Data partially support the hypothesis in that these two groups of men are similar with regard to their HIV status. We do find the sex workers to be different, however, in their being less likely to engage in safe sex practices. We provide an explanation for why this has not lead to their having a higher rate of seropositivity.  相似文献

We sought to identify factors associated with delayed diagnosis of human immunodeficiency virus (HIV; testing HIV-seropositive 6 months or more after HIV seroconversion), by comparing delayed testers to non-delayed testers (persons who were diagnosed within 6 months of HIV seroconversion), in King County, Washington among men who have sex with men (MSM). Participants were recruited from HIV testing sites in the Seattle area. Delayed testing status was determined by the Serologic Testing Algorithm for Recent HIV Seroconversion or a self-reported previous HIV-negative test. Quantitative data on sociodemographic characteristics, health history, and drug-use and sexual behaviors were collected via computer-assisted self-interviews. Qualitative semi-structured interviews regarding testing and risk behaviors were also conducted. Multivariate analysis was used to identify factors associated with delayed diagnosis. Content analysis was used to establish themes in the qualitative data. Out of the 77 HIV-seropositive MSM in this sample, 39 (51%) had evidence of delayed diagnosis. Factors associated with delayed testing included being African-American, homeless, “out” to 50% or less people about male-male sex, and having only one sex partner in the past 6 months. Delayed testers often cited HIV-related sickness as their reason for testing and fear and wanting to be in denial of their HIV status as reasons for not testing. Delayed testers frequently did not identify as part of the MSM community, did not recognize that they were at risk for HIV acquisition, and did not feel a responsibility to themselves or others to disclose their HIV status. This study illustrates the need to further explore circumstances around delayed diagnosis in MSM and develop outreach methods and prevention messages targeted specifically to this potentially highly marginalized population in order to detect HIV infections earlier, provide HIV care, and prevent new infections.  相似文献

This qualitative study examined sex work among internally displaced male and transgender female sex workers in Bogotá, Colombia. Internal displacement has occurred in Colombia as a result of decades of conflict among armed groups and has created large-scale migration from rural to urban areas. Informed by the polymorphous model of sex work, which posits that contextual conditions shape the experience of sex work, we examined three main research questions. The first dealt with how internal displacement was related to the initiation of sex work; the second concerned the effect of agency on sex worker satisfaction; and the third examined how sex work in this context was related to HIV and other risks. Life history interviews were conducted with 26 displaced individuals who had done sex work: 14 were men who have sex with men and 12 were transgender women (natal males). Findings revealed that many participants began doing sex work in the period immediately after displacement, because of a lack of money, housing, and social support. HIV risk was greater during this time due to limited knowledge of HIV and inexperience negotiating safer sex with clients. Other findings indicated that sex workers who exerted more control and choice in the circumstances of their work reported greater satisfaction. In addition, we found that although many sex workers insisted on condom use with clients, several noted that they would sometimes have unprotected sex for additional money. Specific characteristics affecting the experience of sex work among the transgender women were also discussed.  相似文献

Background

The present permanent deferral policy in Israel for MSM was established in 1977 and was based on the previous (now outdated) USA Food and Drug Administration standards. This study analyses epidemiological data regarding blood donations among MSM, in order to estimate the risk for HIV transfusion transmitted infection (TTI) if the policy is changed to allow at-risk MSM to donate blood.

Methods

An Excel based spreadsheet model integrated demographic, epidemiological data from the HIV National Register, laboratory, blood donation and testing data in order to calculate TTI due to false-negatives in known HIV+ donors, windows period donations, asymptomatic carriers and laboratory misclassification errors. A sensitivity analysis of our estimated TTIs for deferral periods for MSM was performed based on a literature review regarding this overall policy issue worldwide.

Results

MSM in Israel have a considerably higher relative risk (RR) of both prevalence (115) and incidence (143) of being HIV+ than persons without a risk factor. Allowing MSM to donate blood, without any deferral period, will add an additional five HIV TTI cases over the next decade. Imposition of a 1 or 5 years deferral of abstinence will increase the number of HIV TTI cases only by 0.10 and 0.05 cases, respectively.

Conclusion

A 1 year deferral period for blood donations from MSM in Israel is recommended.

The exchange of semen, often referred to as “cum play,” has featured in gay literature and may be a unique aspect of many gay men’s sexual behavior. We investigated the prevalence of “cum play” and its context among 1153 HIV-negative and 147 HIV-positive Australian gay men in an online survey. Receptive cum play (partner ejaculating or rubbing his semen over participant’s anus, or participant using partner’s semen as lubricant) was reported by one in six HIV-negative and one quarter of HIV-positive men on the same occasion of protected anal intercourse with a casual partner (PAIC). HIV-negative men who engaged in receptive cum play during PAIC often believed that their partner was HIV seroconcordant and tended to trust that partner. They were also generally more optimistic about the likelihood of HIV transmission, and they often only used condoms at their partners’ instigation. Cum play was not uncommon and highlights the narrowness (or danger) of focusing on condom use without considering the implications of broader sexual practices and their meaning for sexual health promotion. “Safe sex” for some gay and bisexual men does not necessarily mean consistent commitment to condom use or to avoiding semen exchange. Many feel confident in their knowledge of their partner’s HIV serostatus and only use condoms with these partners at their partner’s request. Their commitment to safe sex may not necessarily be compromised by their practice of cum play, but the extent to which this could represent a risk for HIV transmission depends on the reliability of their assessment of their partners’ HIV serostatus.  相似文献

Despite increasing rates of HIV infection among young men who have sex with men (YMSM), only a minority participate in formal HIV prevention efforts. Semi-structured mixed-methods interviews were conducted with a diverse sample of YMSM (N?=?100, M age?=?25.0?years) in Los Angeles, California, to identify facilitators and barriers to participation in HIV prevention programs. Summative content analyses were used to evaluate transcribed field notes from these interviews. Results showed that 28.0?% of all participants had previously attended an HIV prevention program, and that 21.3?% of those who were also asked if they had ever participated in any research pertaining to HIV prevention had done so. A significantly higher percentage of those who had participated in HIV prevention programs had been tested for HIV in the past 6?months compared to those who had not (p?<?.05). The most frequently mentioned barriers to participation in such a program were being too busy to attend (12.0?%), not perceiving themselves to be at risk for HIV infection (14.0?%), and believing that they already knew everything they needed to know about HIV transmission (23.0?%). YMSM suggested that future interventions should use technology (e.g., the Internet, mobile devices), engage their social networks, and highlight HIV prevention as a means for community connection. Collectively, these results provide some explanations for why YMSM account for a minority of HIV prevention program participants and offer possible directions for future HIV prevention efforts that target YMSM.  相似文献

Young black men who have sex with men (YBMSM) are experiencing high and rising rates of HIV infection, more than any other age-risk group category in the USA. Contributors to HIV risk in this group remain incompletely elucidated. We conducted exploratory qualitative interviews with 20 HIV-positive YBMSM aged 17–24 and found that father–son relationships were perceived to be important sociocontextual influences in participants’ lives. Participants discussed the degree of their fathers’ involvement in their lives, emotional qualities of the father–son relationship, communication about sex, and masculine socialization. Participants also described pathways linking father–son relationships to HIV risk, which were mediated by psychological and situational risk scenarios. Our thematic analysis suggests that father–son relationships are important to the psychosocial development of YBMSM, with the potential to either exacerbate or attenuate sexual risk for HIV. Interventions designed to strengthen father–son relationships may provide a promising direction for future health promotion efforts in this population.  相似文献

Heterosexual casual sex is routinely depicted as a physically, socially, and psychologically “risky” practice. This is the case in media accounts, psychological research, and other academic work. In this article, we examine 15 men’s and 15 women’s talk about casual sex from a discursive psychological stance to achieve two objectives. Firstly, we confirm the categories of risk typically associated with casual sex but expand these to include a domain of risks related to (gendered) identities and representation. Men’s talk of risk centered on concerns about sexual performance, whereas women’s talk centered on keeping safe from violence and sexual coercion. The notion of a sexual reputation was also identified as a risk and again manifested differently for men and women. While women were concerned about being deemed promiscuous, men displayed concern about the quality of their sexual performance. Secondly, within this talk about risks of casual sex, the participants’ identities were identified as “at risk” and requiring careful management within the interview context. This was demonstrated by instances of: keeping masculinity intact in accounts of no erection, negotiating a responsible subject position, and crafting agency in accounts of sexual coercion—in the participants’ talk. We argue that casual sex, as situated within dominant discourses of gendered heterosexuality, is a fraught practice for both men and women and subject to the demands of identity representation within co-present interactions.  相似文献

Several recent studies have sought to elaborate upon the applicability and validity of respondent-driven sampling (RDS) to find hard-to-reach samples in general and men who have sex with men (MSM) in particular. Few published studies have elucidated the characteristics associated with initial RDS participants (“seeds”) who successfully recruited others into a study. A total of 74 original seeds were analyzed from four Massachusetts studies conducted between 2006 and 2008 that used RDS to reach high-risk MSM. Seeds were considered “generative” if they recruited two or more subsequent participants and “non-generative” if they recruited zero or one participant. Overall, 34% of seeds were generative. In separate multivariable logistic regression models controlling for age, race, health insurance, HIV status, and the study for which the seed was enrolled, unprotected anal sex in the past 12 months [adjusted odds ratio (AOR) = 6.68; 95% confidence interval (95% CI) = 1.27–35.12; p = 0.03], cocaine use during sex at least monthly during the past 12 months (AOR = 8.81; 95% CI = 1.68–46.27; p = 0.01), and meeting sex partners at social gatherings (AOR = 7.42; 95% CI = 1.58–34.76; p = 0.01) and public cruising areas (AOR = 4.92; 95% CI = 1.27–19.01; p = 0.02) were each significantly associated with increased odds of being a generative seed. These findings have methodological and practical implications for the recruitment of MSM via RDS. Finding ways to identify RDS seeds that are consistently generative may facilitate collecting a sample that is closer to reflecting the MSM who live in all of the communities in a given location or study sample.  相似文献

This study sought to understand the cost, quality of, and access to health care for the insured population in the context of spillover effects resulting from community-level uninsurance. We examined the health care access, quality, and cost experienced by insured Latina mothers in two communities, Minneapolis, Minnesota and McAllen, Texas. These communities differ substantially by the size of the local population without health insurance coverage. Four focus groups were conducted with insured Latina mothers who were caring for at least one child in their household. Eleven and thirteen mothers participated in each community, respectively. The experiences of the insured population in McAllen were substantially different from the experiences of the insured population in Minneapolis. The perceptions of health care quality and access by insured Latina mothers were substantially lower in McAllen while out-of-pocket costs were perceived to be higher in Minneapolis. Our study provides key insights about the US health care system and the role that the relative size of the local uninsured population may have in impacting the health care experiences of the insured. Health insurance coverage rates are expected to increase substantially across US communities within the next few years but local health care system challenges related to cost, quality, and access will remain for both the insured and the uninsured.  相似文献

Male-to-female transgender persons are thought to be “vectors” for HIV/STI transmission, yet little quantitative information exists about the risk behavior of their male sexual partners who may serve as a “bridge” for HIV transmission into the general population. As part of an online survey examining the sexual risk behavior of Latino men who have sex with men (N = 1,026), we identified 44 (4%) participants who reported having had sex with a transgender partner. Compared with a randomly selected sub-sample of 200 men who did not report sex with a transgender person, sexual partners of transgender persons were almost three times more likely to have had unprotected sexual intercourse in the last three months. In addition, men who had sex with transgender persons were more likely to be HIV-positive; married, separated, or divorced; identify as bisexual or straight; have sex with women; and live in rural or small town communities. Regression analysis revealed that community size, sexual compulsivity, and having had a transgender partner were independent predictors of unprotected sex. Among Latino men who have sex with men, men with a history of sex with a transgender person appear more likely to be sexually compulsive and at greater risk for HIV and other sexually transmitted infections. These men may, therefore, also serve as a “bridge” for HIV transmission to (as opposed to from) the transgender population.  相似文献
