"Live a normal life": Constructions of resilience among people in mixed HIV status relationships in Canada

Positive Plus One is a mixed-methods study of long-term mixed HIV-serostatus relationships in Canada (2016-19). Qualitative interviews with 51 participants (10 women, 41 men, including 27 HIV-positive and 24 HIV-negative partners) were analyzed using inductive thematic analysis to examine notions of relationship resilience in the context of emerging HIV social campaigns. Relationship resilience meant finding ways to build and enact life as a normal couple, that is, a couple not noticeably affected by HIV, linked to the partner with HIV maintaining viral suppression and achieving "undetectable = untransmittable" (U = U). Regardless of serostatus, participants with material resources, social networks, and specialized care were better able to construct resilience for HIV-related challenges within their relationships. Compared to heterosexual couples and those facing socioeconomic adversity, gay and bisexual couples were easier able to disclose, and access capital, networks and resources supporting resilience. We conclude that important pathways of constructing, shaping, and maintaining resilience were influenced by the timing of HIV diagnosis in the relationship, access to HIV-related information and services, disclosure, stigma and social acceptance.

A national recruitment strategy for HIV-serodiscordant partners living in Canada for the Positive Plus One study: a mixed-methods study

Background

With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies.

Methods

PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners.

Results

We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner.

Conclusions

Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of “happy couple” bias.

Disclosure of HIV-serodiscordant relationships and association with viral suppression: results from the Positive Plus One study

BACKGROUND

Little is known about the effects of disclosure of HIV-serodiscordant relationships on clinical outcomes. We aimed to evaluate the effect of relationship disclosure on HIV viral suppression, and hypothesized that disclosure by HIV-positive and HIV-negative partners would be associated with viral suppression in the HIV-positive partner.

METHODS

We conducted a Canadian national online and telephone-administered survey of HIV-positive and HIV-negative partners in serodiscordant relationships. The primary outcome was self-reported viral suppression. Multivariable analyses were undertaken using Firth logistic regression.

RESULTS

We recruited 540 participants in current serodiscordant relationships (n = 228 HIV-negative; n = 312 HIV-positive). Similar proportions of HIV-positive and HIV-negative partners disclosed their relationship to healthcare professionals (82% v. 76%, p = 0.13). Among HIV-positive partners, disclosure of the relationship to healthcare professionals increased the odds of viral suppression (aOR = 4.7; CI: 2.13, 10.51) after adjusting for age, education, and relationship turmoil due to HIV. Increasing age (aOR = 1.28; 95% CI = 1.07, 1.55) and education (aOR = 2.43; 95% CI = 1.15, 5.26) were also associated with viral suppression. Among HIV-negative partners, relationship disclosure was not associated with viral suppression and HIV-negative heterosexual men were less likely to report that their HIV-positive partners were virally suppressed (aOR = 0.24; CI: 0.09, 0.61).

CONCLUSIONS

Disclosure of HIV-serodiscordant status by HIV-positive participants to healthcare professionals was associated with increased odds of viral suppression. Similar effects were not evident among HIV-negative participants. Future work should explore factors that empower relationship disclosure and incorporate them into supportive services for HIV-serodiscordant relationships.

Dual pharmaceutical citizenship: Exploring biomedicalization in the daily lives of mixed HIV-serostatus couples in Canada

Positive Plus One is the first large-scale mixed methods study of mixed HIV serostatus couples in Canada. We aimed to understand how biomedicalization i.e., a social process of commodification and expansion of the jurisdiction of medicine over health, influenced the everyday relationships of these couples. We completed 51 semi-structured interviews among a purposive sample of HIV-positive (n = 27) and HIV-negative (n = 24) partners in current or past mixed-serostatus relationships. Participants were recruited after completing an online survey where they consented to be re-contacted for qualitative interviews. Participants represented a diversity of sexual orientations, gender identities, and other sociodemographic characteristics. Drawing on inductive thematic analysis to identify patterns within couples, across serostatus and sexual orientations, we argue that everyday lives of mixed-serostatus couples were shaped by biomedical knowledge and enacted through routine adherence to obtain and maintain viral load undetectability. Our findings illustrated the importance of learning biomedical knowledge for mixed-serostatus couples in this study, the empowering influence of undetectable = untransmittable (UU) discourse, and its role in rendering HIV mundane through routine ART adherence. We introduce the concept of 'dual pharmaceutical citizenship' to underscore a process by which particular biopolitical and biomedical expectations are fulfilled in mixed-serostatus relationships. These findings have implications for people who do not readily accept or have access to biomedical knowledge, particularly when treatment-as-prevention frames a "right" and "wrong" approach to HIV management. Future studies should focus on couples where at least one partner does not readily accept or have access to biomedical knowledge.

Black PRAISE: engaging Black congregations to strengthen critical awareness of HIV affecting Black Canadian communities

In Canada, HIV disproportionately affects Black communities. Though Black faith leaders play an influential role engaging Black communities around social care and social justice, their response to HIV has been somewhat muted. Black PRAISE is a novel intervention for Black churches to strengthen congregants' critical awareness of HIV affecting Black communities. A multi-stakeholder team developed and tested the intervention in 2016 - 17 among six churches in the province of Ontario, where more than half of Black Canadians reside, using a community-based participatory approach. Specifically, the intervention aimed to strengthen how congregants understand HIV among Black communities and reduce their level of stigma toward people living with HIV. We addressed critical awareness among the participating congregations through (i) disseminating a booklet with validated information that promoted critical health literacy related to HIV; (ii) enabling pastors to deliver a sermon on love, compassion and social justice; and (iii) developing and screening a short film that featured Black Canadians discussing their experiences of HIV-related stigma. We assessed changes in knowledge and stigma by surveying congregants (N = 173) at baseline and two follow-ups using validated instruments and other measures. Through Black PRAISE, congregants significantly increased their HIV-related knowledge; moreover, exposure to all the intervention components was associated with a significantly reduced level of stigma. A likely strategic outcome of Black PRAISE is that churches are empowered to help strengthen Black people's community-based response to HIV and join efforts to eliminate the structural conditions that increase Black people's vulnerability to HIV.

Examining HIV-related stigma among African, Caribbean, and Black church congregants from the Black PRAISE study in Ontario, Canada

HIV-related stigma impedes adoption and implementation of effective HIV prevention and treatment strategies. It may also exacerbate racial/ethnic HIV disparities. Given high levels of religious observance within African, Caribbean, and Black (ACB) communities and the social capital that faith-based organizations hold, these entities may be promising venues for stigma-remediation and effective partners in community-based, HIV-focused programing. However, more research is needed to understand HIV-related stigma in these institutions. This study examines HIV-related stigma among six ACB churches in Ontario, Canada. Surveys were distributed to ACB attendees (N = 316) and linear regressions determined relationships between HIV-related stigma and stigma subdomains with demographics, greater disagreement with same-sex relationships, HIV knowledge, and religiosity. Greater disagreement with same-sex relationships was the only variable associated with the HIV-related stigma scale and all of its subscales. Age, gender, HIV knowledge, religiosity, contact with persons living with HIV, and length of time in Canada were associated with varying aspects of HIV-related stigma. Findings can inform the development of HIV-related stigma interventions and the characteristics of individuals these efforts should target to achieve maximum impact.

Love, Judgement and HIV: Congregants' Perspectives on an Intervention for Black Churches to Promote Critical Awareness of HIV Affecting Black Canadians

We assess participants' experience of Black Pastors Raising Awareness and Insight of Stigma through Engagement (Black PRAISE), an intervention for Black churches to promote critical awareness of HIV affecting Black Canadian communities. We used a community-based participatory approach to implement Black PRAISE among six churches in the Greater Toronto Area and Ottawa, in October-November 2016. For the intervention, congregants received a booklet with validated HIV-related information, attended a sermon on compassion and justice, viewed a short film on HIV-related stigma, and completed baseline and follow-up surveys to evaluate the effectiveness of the intervention. We then conducted in-depth interviews with 18 pastors and congregants from the six churches to explore how they experienced the intervention. Three major themes emerged from an iterative exploration of the thematic content of the interviews: the beneficial impact of the intervention; reconciling the moral and theological issues of their faith with the social reality of HIV and stigma; and perspectives on future stigma reduction efforts. Participants spoke approvingly about Black PRAISE and supported stigma reduction but acknowledged uncertainties about their capacity to actualise their commitment. The main overarching lessons from Black PRAISE are as follows: first, our results support a community-based participatory approach to productively engaging Black congregations in stigma reduction and health promotion; second, promising or successful interventions incorporate multiple components to promote critical awareness about the specific health issue for Black life and wellbeing; and third, interventions are more likely to succeed if they support critical reflection on the underlying conceptual issues, implicit assumptions and belief systems among the professional and lay stakeholders.

Interventions to improve retention-in-care and treatment adherence among patients with drug-resistant tuberculosis: a systematic review

The global loss to follow-up (LTFU) rate among drug-resistant tuberculosis (DR-TB) patients remains high at 15%. We conducted a systematic review to explore interventions to reduce LTFU during DR-TB treatment.We searched for studies published between January 2000 and December 2017 that provided any form of psychosocial or material support for patients with DR-TB. We estimated point estimates and 95% confidence intervals of the proportion LTFU. We performed subgroup analyses and pooled estimates using an exact binomial likelihood approach.We included 35 DR-TB cohorts from 25 studies, with a pooled proportion LTFU of 17 (12-23)%. Cohorts that received any form of psychosocial or material support had lower LTFU rates than those that received standard care. Psychosocial support throughout treatment, via counselling sessions or home visits, was associated with lower LTFU rates compared to when support was provided through a limited number of visits or not at all.Our review suggests that psychosocial support should be provided throughout DR-TB treatment in order to reduce treatment LTFU. Future studies should explore the potential of providing self-administered therapy complemented with psychosocial support during the continuation phase.

Childhood Maltreatment, Bullying Victimization, and Psychological Distress Among Gay and Bisexual Men

Sexual minority men report higher psychological distress than heterosexual men, including depression and anxiety. Research suggests that these health disparities may be due to the heightened stressors that gay, lesbian, and bisexual individuals experience. Some of these stressors occur early on in life, such as childhood abuse and bullying, and may include stressors that are topically related to sexual minority status, such as anti-gay bullying and teasing for gender nonconformity to masculine gender norms. We tested a structural equation model on the association between negative childhood experiences and adult psychological distress among 304 gay and bisexual men. The model fit the data well, and demonstrated an indirect effect of negative childhood experiences on adult psychological distress via dysfunctional thoughts toward oneself. The results integrate the childhood abuse and anti-gay bullying victimization literatures by showing that both forms of adverse childhood experiences are associated with adult psychological distress. The findings suggest the benefit of treatments to reduce negative, dysfunctional thoughts among gay and bisexual men who have experienced adverse childhood events.

Community HIV Prevention: What Can We Learn from the Perceptions and Experiences of HIV-Positive Women Living in Metropolitan Toronto, Canada?

Researchers and practitioners have pointed to a number of gender issues that influence women's ability to practice safer sex and protect themselves from HIV. Many of the studies, however, are based on research with HIV-negative women. This qualitative study sought to explore with forty HIV-positive women (for whom prevention was not effective) the types of issues that they believe need to be addressed to ensure effective prevention for other women. Participants also were asked to discuss the impact of HIV on their sexual lives as a means of exploring the types of issues that are needed to ensure effective secondary prevention efforts. Many of the women interviewed suggested that not only is there a need to challenge gender inequities as a means of ensuring women's protection against HIV, but that different “accommodation strategies” are necessary in the short-term to ensure women's health. In addition, many of the women pointed to the fact that women's identity—as wife or girlfriend—is often based on the belief that their sexual relationships are “safe” from HIV. The importance of addressing gender identity (rooted in gender inequities) when developing HIV prevention efforts is discussed.

A Comparison of Web and Telephone Responses From a National HIV and AIDS Survey

BACKGROUND

Response differences to survey questions are known to exist for different modes of questionnaire completion. Previous research has shown that response differences by mode are larger for sensitive and complicated questions. However, it is unknown what effect completion mode may have on HIV and AIDS survey research, which addresses particularly sensitive and stigmatized health issues.

OBJECTIVES

We seek to compare responses between self-selected Web and telephone respondents in terms of social desirability and item nonresponse in a national HIV and AIDS survey.

METHODS

A survey of 2085 people in Canada aged 18 years and older was conducted to explore public knowledge, attitudes, and behaviors around HIV and AIDS in May 2011. Participants were recruited using random-digit dialing and could select to be interviewed on the telephone or self-complete through the Internet. For this paper, 15 questions considered to be either sensitive, stigma-related, or less-sensitive in nature were assessed to estimate associations between responses and mode of completion. Multivariate regression analyses were conducted for questions with significant (P≤.05) bivariate differences in responses to adjust for sociodemographic factors. As survey mode was not randomly assigned, we created a propensity score variable and included it in our multivariate models to control for mode selection bias.

RESULTS

A total of 81% of participants completed the questionnaire through the Internet, and 19% completed by telephone. Telephone respondents were older, reported less education, had lower incomes, and were more likely from the province of Quebec. Overall, 2 of 13 questions assessed for social desirability and 3 of 15 questions assessed for item nonresponse were significantly associated with choice of mode in the multivariate analysis. For social desirability, Web respondents were more likely than telephone respondents to report more than 1 sexual partner in the past year (fully adjusted odds ratio (OR)=3.65, 95% CI 1.80-7.42) and more likely to have donated to charity in the past year (OR=1.63, 95% CI 1.15-2.29). For item nonresponse, Web respondents were more likely than telephone respondents to have a missing or "don't know" response when asked about: the disease they were most concerned about (OR=3.02, 95% CI 1.67-5.47); if they had ever been tested for HIV (OR=8.04, 95% CI 2.46-26.31); and when rating their level of comfort with shopping at grocery store if the owner was known to have HIV or AIDS (OR=3.11, 95% CI 1.47-6.63).

CONCLUSION

Sociodemographic differences existed between Web and telephone respondents, but for 23 of 28 questions considered in our analysis, there were no significant differences in responses by mode. For surveys with very sensitive health content, such as HIV and AIDS, Web administration may be subject to less social desirability bias but may also have greater item nonresponse for certain questions.

Symptomatic primary HIV infection or risk experiences? Circumstances surrounding HIV testing and diagnosis among recent seroconverters

Our objective was to understand the circumstances surrounding HIV testing among recent HIV seroconverters ( n = 80) compared to HIV-negative controls ( n = 106) in Ontario, Canada using self-reported interview data. Diagnosis of symptomatic primary HIV infection (SPHI) was defined as diagnosis by the participant's physician. Testing in response to symptoms was reported by 42% of seroconverters vs 12% of controls. More controls than seroconverters tested in response to risk behaviour (70% vs 50%) or from a desire to know their status (34% vs 12%). Among seroconverters, 76% reported 'flu-like' illness during the time period of infection, 66% had symptoms consistent with SPHI, and 35% reported a physician's diagnosis of SPHI. Compared to seroconverters with undiagnosed SPHI, more of those diagnosed with SPHI had rash (odds ratio = 4.5). SPHI plays a significant role in HIV testing and subsequent early diagnosis in this population. More seroconversions could be diagnosed with better patient and physician awareness of its symptoms.

Syringe Acquisition, Peer Exchange and HIV Risk

To explore syringe access patterns and implications for HIV prevention programming, data from qualitative interviews (n=120) with injection drug users (IDU) and an evaluation of a satellite syringe-exchange program (SEP) were used. Three patterns were identified: IDUs who stockpile supplies to meet their own needs and to provide secondary distribution to friends and drug-using associates; IDUs who keep a several-days supply of syringes available, primarily for their own use; and IDUs who usually obtain equipment at the time of obtaining drugs, in some cases unsterile equipment from other injectors. The first two types of injectors are typically in stable housing, while the last group are generally in unstable housing. This analysis highlights the very direct link between adequate housing and safer injection practices for HIV prevention, and points to the need to advocate more broadly on behalf of IDUs for appropriate housing, harm-reduction and social services.

Design and implementation of a sexual health intervention for migrant construction workers situated in Shanghai, China

BACKGROUND

China's growing population of internal migrants has exceeded 236 million. Driven by rapid development and urbanization, this extreme population mobility creates opportunities for transmission of HIV and sexually-transmitted infections (STI). Large numbers of rural migrants flock to megacities such as Shanghai in search of employment. Although migrants constitute a key population at heightened risk of acquiring HIV or an STI, there is a lack of easily accessible sexual health services available for them. In response, we designed a short, inexpensive sexual health intervention that sought to improve HIV and STI knowledge, while reducing stigma, risky sexual behaviour, and sexual transmission of HIV and STI among migrant construction workers (MCW) situated in Shanghai, China.

RESULTS

We implemented a three-armed, community-randomized trial spread across three administrative districts of Shanghai. The low-intensity intervention included educational pamphlets. The medium-intensity intervention included pamphlets, posters, and videos. The high-intensity intervention added group and individual counselling sessions. Across 18 construction sites, 1871 MCW were allocated at baseline to receive one intervention condition. Among baseline participants, 1304 workers were retained at 3-months, and 1013 workers were retained at 6-months, representing a total of 579 person-years of follow-up. All workers, regardless of participation, had access to informational materials even if they did not participate in the evaluation. Overall outputs included: 2284 pamphlets distributed, 720 posters displayed, 672 h of video shown, 376 participants accessed group counselling, and 61 participants attended individual counselling sessions. A multivariable analysis of participation found that men (aOR = 2.2; 95 % CI 1.1, 4.1; p = 0.036), workers situated in Huangpu district (aOR = 5.0; 95 % CI 2.6, 9.5; p < 0.001), and those with a middle school education (aOR = 1.9; 95 % CI 1.2, 3.0; p = 0.01) were more likely to have participated in intervention activities.

CONCLUSION

A brief educational intervention that prioritized ease of delivery to a highly mobile workforce was feasible and easily accessed by participants. Routine implementation of sexual health interventions in workplaces that employ migrant labour have the potential to make important contributions toward improving HIV and STI outcomes among migrant workers in China's largest cities.

A scoping review and thematic analysis of social and behavioural research among HIV-serodiscordant couples in high-income settings

BACKGROUND

While HIV incidence has stabilized in many settings, increases in health and wellbeing among many people living with HIV/AIDS suggest that the number of HIV-serodiscordant relationships is growing. Given the deficit of reviews addressing social and behavioural characteristics of HIV-serodiscordant couples within high-income settings, our objective was to understand the scope of the published literature, identify evidence gaps, and suggest future research needs.

METHODS

Ten electronic databases were searched. Studies were included if they were reported in English, used primary data, were from the combination antiretroviral (cART) era (>1996), reported on social or behavioural aspects, included any fraction of primary (i.e., stable) relationships, and were conducted in high-income settings. Studies that identified their unit of analysis as either the dyad or individual member of the couple were included. Studies were coded according to a thematic framework.

RESULTS

Included studies (n = 154) clustered into eight themes: risk behaviours (29%), risk management (26%), reproductive issues (12%), relationship quality (9%), serostatus disclosure (7%), adherence to antiretroviral therapy (7%), vulnerability (5%), and social support (3%). The proportion of studies conducted among heterosexual couples, same-sex male couples, and mixed cohorts were 42%, 34%, and 24%, respectively. Most studies (70%) were conducted in the United States, 70% of all studies were quantitative (including interventions), but only one-third were focused on couples (dyads) where both partners are recruited to a study. Over 25% of studies focused on sexual risk among same-sex male couples.

CONCLUSIONS

Future research efforts should focus on the interrelationship of risk management strategies and relationship quality, social determinants of health and wellbeing, HIV testing, vulnerable populations, reproductive issues among same-sex couples, disclosure of serodiscordant status to social networks, dyadic studies, population-based studies, and interventions to support risk management within couples. Additional population-based studies and studies among marginalized groups would be helpful for targeting research and interventions to couples that are most in need. As HIV-positive partners are typically the link to services and research, innovative ways are needed for reaching out to HIV-negative partners. Our review suggests that significantly more research is needed to understand the social and behavioural contexts of HIV-serodiscordant relationships.

Impact evaluation of a community-based intervention to reduce risky sexual behaviour among female sex workers in Shanghai, China

Background

Female sex workers (FSWs) are at risk for sexually transmitted infections (STIs), including HIV. We implemented an HIV/STI preventive intervention among FSWs in Shanghai that aimed to increase condom use, improve HIV knowledge, and reduce STI and HIV incidence.

Methods

From six districts in Shanghai, 750 randomly selected venue-based FSWs were allocated to either a behavioural intervention or control group. In the intervention and control groups, 221 and 278 participants, respectively, had at least one follow-up at three or six months. In analysis, we randomly selected 57 lost to follow-up cases in the intervention group and imputed baseline values to equalize the arms at n = 278 (74.1% follow-up rate in each group). The impacts of the intervention on condom use, HIV/STI risk perception and knowledge, and STI incidence were assessed using either a logistic or linear model, adjusting for the baseline measure of the outcome and venue type.

Results

The intervention improved consistent condom use with any partner type in the previous month (AOR = 2.09, 95% CI, 1.43-3.04, p = 0.0001). Consistent condom use with clients in the three most recent sex acts increased in both arms, and with primary partners in the intervention arm, but there was no difference between groups after adjusting for baseline condom use and venue type. There were no differences in cumulative incidence of any STI (i.e., chlamydia, gonorrhoea, syphilis) between groups. HIV transmission knowledge (p = 0.0001), condom use skill (p = 0.0421), and self-efficacy for using condoms (p = 0.0071) were improved by the intervention. HIV-related stigma declined (p = 0.0119) and HIV and STI risk perception were improved (4.6 to 13.9%, and 9.4 to 20.0%, respectively). The intervention was associated with these improvements after adjusting for the baseline measure and venue type.

Conclusion

Following a preventive intervention among Shanghai FSWs, our findings demonstrate that a simple, community-based educational intervention improved overall condom use, HIV and STI knowledge, and attitudes in relation to HIV/AIDS. The intervention should be implemented widely after tailoring educational materials regarding condom negotiation with different partner types (i.e., commercial sex clients and primary partners).

38. Anal cancer screening in HIV primary care: uptake and outcomes

Background Anal cytology (Pap tests) plus high-resolution anoscopy (HRA) as required are felt to be the optimal approach to anal cancer screening. We present preliminary results from STANDOUT, a study of acceptability and outcomes of anal cancer screening of HIV+ MSM in primary care practices. Methods: All previously unscreened HIV+ MSM from 9 HIV primary care practices, were invited by email or letter to receive anal cancer screening. Responders had anal cytology done at specially arranged or routine clinic visits. Those with high-grade squamous intraepithelial lesions (HSIL) on anal cytology were offered HRA to assess for anal intraepithelial neoplasia (AIN). Those with AIN 2/3 on biopsy were randomised to receive trichloroacetic acid (TCA) or infrared coagulator (IRC) treatments. Results: 1733 patients were invited and 921 (53%) agreed to have anal cytology done. Among those screened, 3 had unsatisfactory samples; 596 (65%) had normal cytology, 253 (27%) had low-grade squamous intraepithelial lesions (LSIL) and 69 (7.5%) had HSIL. HRA results are available in 64: 41 (64%) had histologic high-grade disease (29 had AIN2 and 12 had AIN3). Those with AIN 2/3 were randomised to receive treatment with TCA (16 patients) or IRC (18 patients). Treatment successes at 3 months were 6 of 15 patients for TCA (40%) and 11 of 16 patients for IRC (69%). Conclusions: In this sample of HIV+ MSM, about half of those invited for anal cancer screening agreed to have it done. Most with HSIL had histological high-grade disease and were treated. IRC was more successful than TCA at ablating high-grade disease.

Accounts of HIV seroconversion among substance-using gay and bisexual men

Statistical associations between substance use and seroconversion among gay and bisexual men abound. However, these associations often ignore men's own interpretations of their seroconversion. Using in-depth interviews with gay and bisexual men who reported using drugs or alcohol at the time of their seroconversion, we identify how these men explain the events that led to HIV transmission. Whereas a small minority of respondents reported substance use to explain their seroconversion, the majority reported three competing explanations. These participants claimed that they lacked sufficient knowledge about the behavioral risks that led to their seroconversion; that their decision to engage in unsafe sex was because of negative personal affect; and that they "trusted the wrong person." We link these findings to prevention and suggest that gay and bisexual men who use substances for recreational purposes will benefit from prevention efforts designed to address issues of gay and bisexual men rather than substance-using men.

Experiences of and responses to HIV among African and Caribbean communities in Toronto, Canada

African and Caribbean communities in Canada and other developed countries are disproportionately affected by HIV/AIDS. This qualitative study of African and Caribbean communities in Toronto sought to understand HIV-related stigma, discrimination, denial and fear, and the effects of multiple intersecting factors that influence responses to the disease, prevention practices and access to treatment and support services. Semi-structured interviews were conducted with 30 HIV-positive men and women and focus groups were conducted with 74 men and women whose HIV status was negative or unknown. We identified a range of issues faced by African and Caribbean people that may increase the risk for HIV infection, create obstacles to testing and treatment and lead to isolation of HIV-positive people. Our findings suggest the need for greater sensitivity and knowledge on the part of healthcare providers; more culturally specific support services; community development; greater community awareness; and expanded efforts to tackle housing, poverty, racism and settlement issues.

Prevalence of HIV and hepatitis C virus infections among inmates of Ontario remand facilities

BACKGROUND

Each year more than 56 000 adult and young offenders are admitted to Ontario's remand facilities (jails, detention centres and youth centres). The prevalence of HIV infection in Ontario remand facilities was last measured over a decade ago, and no research on the prevalence of hepatitis C virus (HCV) infection has been conducted in such facilities. We sought to determine the prevalence of HIV infection, HCV infection and HIV-HCV coinfection among inmates in Ontario's remand facilities.

METHODS

A voluntary and anonymous cross-sectional prevalence study of HIV and HCV infections was conducted among people admitted to 13 selected remand facilities across Ontario between Feb. 1, 2003, and June 20, 2004. Data collection included a saliva specimen for HIV and HCV antibody screening and an interviewer-administered survey. Prevalence rates and 95% confidence intervals were calculated and examined according to demographic characteristics, region of incarceration and self-reported history of injection drug use.

RESULTS

In total, 1877 participants provided both a saliva specimen and survey information. Among the adult participants, the prevalence of HIV infection was 2.1% among men and 1.8% among women. Adult offenders most likely to have HIV infection were older offenders (> or = 30 years) and injection drug users. The prevalence of HCV infection was 15.9% among men, 30.2% among women and 54.7% among injection drug users. Adult offenders most likely to have HCV infection were women, older offenders (> or = 30 years) and injection drug users. The prevalence of HCV-HIV coinfection was 1.2% among men and 1.5% among women. It was highest among older inmates and injection drug users. Among the young offenders, none was HIV positive and 1 (0.4%) was HCV positive. On the basis of the study results, we estimated that 1079 HIV-positive adults and 9208 HCV-positive adults were admitted to remand facilities in Ontario from Apr. 1, 2003, to Mar. 31, 2004.

INTERPRETATION

Adult offenders entering Ontario remand facilities have a considerably higher prevalence of HIV and HCV infections than the general population.

Psychosocial impact of repeat HIV-negative testing: a follow-up study

Continued sexual risk behavior following repeatedly testing HIV-negative in the Polaris HIV Seroconversion Study (Ontario, Canada) led to this follow-up study which identifies the impact of repeat negative testing among 64 men and women. Repeat HIV-negative testing frequently results in confusion as to what constitutes risk and occasionally to thoughts of HIV immunity. Narrative accounts include beliefs that monogamy constitutes safety from HIV, that psychosocial factors other than repeatedly testing negative leads to risk, and that sexual risk reduction is unsustainable. In conclusion, the repeat negative test experience for some neither clarifies risk behavior nor reinforces sustained risk reduction.

Gay and bisexual men's experiences of bathhouse culture and sex: 'looking for love in all the wrong places'

The aim of this study was to describe gay and bisexual men's experiences of bathhouses and their perceptions of HIV risk associated with sex in this context. Face-to-face, semi-structured interviews were conducted with a purposive sample of gay and bisexual men-14 HIV-positive and 9 HIV-negative-who reported ever frequenting a bathhouse. The sample was selected from the Polaris HIV Seroconversion Study, a longitudinal open cohort study of documented recent seroconverters and HIV-negative controls in Ontario, Canada. Interview transcripts were analysed using a narrative approach. Four major themes were identified concerning views of gay bathhouse culture and environments; moral conceptions of self and others at a bathhouse; identity management at a bathhouse; and psychosocial functions of gay bathhouses. HIV transmission is a salient component of bathhouse culture; therefore, bathhouses are critical environments for the promotion of safer sex activities among gay and bisexual men.

Regional variation in HIV prevalence and risk behaviours in Ontario injection drug users (IDU)

OBJECTIVES

To measure HIV prevalence, risk behaviours, and further service needs in needle exchange programs throughout Ontario, and to conduct regional comparisons.

METHODS

Injection drug users (IDU) recruited through the efforts of needle exchange programme (NEP) staff in 9 Ontario cities during 1997-98 completed questionnaires about their drug use and behaviours and provided saliva and/or dried blood samples for anonymous unlinked HIV testing.

RESULTS

Demographic and drug use characteristics of participants showed great regional variation. HIV prevalence by region ranged from 1.4% to 14.7%. In addition to region, HIV positivity was associated with injecting for more than 5 years, use of (powder) cocaine, use of crack, binge injection (10 or more times per day at least once in the previous 6 months), and being a longer-term NEP user. Sharing of injection equipment, and especially of other drug injection materials such as water and cookers, remain important issues, although much of the sharing reported is with only one other person. Unmet demand for methadone treatment was identified despite changes in regulation of methadone provision designed to make it more accessible.

CONCLUSIONS

This study suggested significant further HIV prevention needs among IDU throughout Ontario. There is also evidence of potential to provide additional services such as methadone at NEPs if the required resources are invested. NEPs that have succeeded in gaining the trust of high-risk IDU offer a means to provide access to needed services.

HIV testing and counseling: test providers' experiences of best practices

Although education is central to HIV testing and counseling, little is known about the educational processes within the testing experience. This study investigated test providers' understandings of testing and counseling best practices. Interviews with a purposive sample of 24 test providers were thematically analyzed. Analysis revealed five best practices specific to HIV education and public health--ensuring information and education for HIV risk reduction, individualization of risk assessment, ensuring test results are given in person, providing information and referrals, and facilitating partner notification--and six practices not specific to HIV counseling relationship building. The latter were building trust and rapport; maintaining professional boundaries; ensuring a comfortable, safe environment; ensuring confidentiality; imparting nonjudgmntal attitude; and self-determination. The identified best practices demonstrated remarkable consistency across respondent subgroups. Although counseling was seen as largely educational and with a preventive focus, it included individualized messages based on assessments of risk, knowledge, and social and cultural characteristics.

Delayed application of condoms is a risk factor for human immunodeficiency virus infection among homosexual and bisexual men

The objective of this analysis was to identify risk factors for recent human immunodeficiency virus (HIV) infection among homosexual and bisexual men in Ontario, Canada, during 1998-2001. Participants were recruited through the provincial HIV diagnostic laboratory and through physicians and community organizations. HIV test results were used to identify recent seroconverters (cases). A subsample of 183 men (62 cases and 121 controls) enrolled in the Polaris HIV Seroconversion Study as of June 2001 was analyzed. This analysis focused on sexual behaviors with partners who were HIV-positive or whose HIV status was unknown. In multiple logistic regression, independent risk factors were identified. Rates of unprotected receptive oral, insertive anal, and receptive anal sex and delayed application of condoms during receptive anal sex (RAS) were significantly higher among cases (97%, 41%, 53%, and 32%, respectively) than among controls (73%, 19%, 14%, and 2%). Independent risk factors for HIV infection were RAS without condoms (odds ratio = 4.4, p = 0.0004) and delayed application of condoms during RAS (odds ratio = 5.8, p = 0.01). There was an association with condom failure (breakage or slippage) during RAS that approached significance (odds ratio = 2.9, p = 0.09). Delayed application of condoms for RAS may result in contact with preejaculatory fluid. This behavior, which to date has received little attention, may pose as much risk for HIV infection as fully unprotected RAS.

Increases in HIV incidence among men who have sex with men undergoing repeat diagnostic HIV testing in Ontario, Canada

OBJECTIVE

To estimate HIV incidence density for different exposure categories among people undergoing repeat testing in Ontario, Canada.

METHODS

Persons using voluntary, diagnostic HIV testing at least twice were identified by computerized and manual record linkage. In the 1992-2000 period, 980 seroconverters and 340 994 repeat negative testers contributed 936 145 person years (PY) of observation. Incidence density (ID) was calculated according to Kitayaporn et al. Poisson regression was used to evaluate differences in incidence.

RESULTS

Among men who have sex with men (MSM), ID declined between 1992-1996, from 1.23 per 100 PY in 1992 to 0.79 per 100 PY in 1996 [relative risk (RR), 0.86 per year; 95% confidence interval (CI), 0.77-0.96]. Subsequently, ID increased to 1.39 per 100 PY in 1999 (RR, 1.18 per year; 95% CI, 1.05-1.34). In 2000, ID was 1.16 per 100 PY but this decrease was not statistically significantly different from 1999. MSM in their twenties had the highest ID in 1992-1996, but in 1996-2000 MSM in their thirties had the highest risk of infection. Among injecting drug users (IDU), ID decreased from 0.64 per 100 PY in 1992 to 0.14 per 100 PY in 2000 (RR, 0.87 per year; 95% CI, 0.80-0.94). Among heterosexuals, annual incidence remained constant at about 0.03 per 100 PY in 1992-2000.

CONCLUSIONS

Increases in ID were identified among MSM from 1996 to 1999. These findings are consistent with other research. Continued vigilance and improved surveillance are needed to better understand and control the epidemic.

Developing effective HIV prevention programs for inmates: results from an Ontario-wide survey

Many studies of the characteristics, behaviours, and prevalence of HIV among those admitted to Canadian correctional facilities indicate that inmates are at increased risk for HIV infection and that they be targeted for HIV interventions. Yet the development and implementation of these programs has been much too slow and, at times, inappropriate to the prison environment. Further, the effectiveness of current and proposed policies and programs must be evaluated to ensure that the goal of reducing HIV transmission is achieved. To address these issues, a team of University of Toronto researchers undertook a study entitled "The Social and Structural Determinants of HIV-Related Risk Behaviours among Prisoners: Implications for Prevention." This study surveyed adult males and females incarcerated in six provincial correctional centres in Ontario. The following provides a brief overview of the study and its results.

Sexual coercion among young street-involved adults: perpetrators' and victims' perspectives

This study explored sexual coercion in dating situations among young adults ages 18-25. Focus group discussions were conducted with a mostly street-involved and sexually diverse (straight, gay, lesbian and bisexual) sample of young adults. While aware of the risks of unsafe sex, getting sex whenever possible or getting sex over with outweighed considerations of safer sex and disease transmission. Participants noted that partners could be manipulated or coerced into sex, using alcohol and drugs; obligations, expectations, and guilt; and exploitation of emotional and economic vulnerability. Overall, participants revealed that these factors led to an increase in total number of sexual events and particularly to unsafe sex. While sexual education and safer sex programs often address sexual negotiation, a focus on changing the behaviors of those who coerce partners into sex is also needed to reduce the risk of HIV transmission.

HIV-positive women living in the metropolitan Toronto area: their experiences and perceptions related to HIV testing. The HIV Women's Study Group

Forty HIV-positive women from diverse socioeconomic backgrounds were interviewed. Most (90%) did not perceive themselves to be at risk of HIV infection prior to knowing their HIV-positive status. The majority (61%) were tested because they developed symptoms, or because someone with whom they were intimate, or their child, tested positive for HIV or became ill. The majority (93%) of the women interviewed indicated that they did not receive both pre- and post-test counselling. The findings from this study suggest that encouraging individuals to be tested if they have engaged in "at risk" activities will not be appropriate for individuals who have no perception of risk, and other strategies to encourage appropriate testing may be needed. This research also suggests that continued emphasis needs to be placed on the counselling process, and that consideration may need to be given to multiple counselling sessions to ensure individuals clearly understand the information provided.

Understanding the intention of gay and bisexual men to take the HIV antibody test

This study offers an explanation for the intention of 1,512 gay and bisexual men to be tested for the HIV antibody. Participants were recruited through 125 gay-identified venues (bars, bathhouses, community dances) across Canada. Self-administered questionnaires assessed respondents' intention to take the test in the next year, predictor variables (e.g., attitudes, the perceived social norm of the gay community, perceived behavioral control, and other constructs such as reasons for not being tested and importance of aspects of the test such as confidentiality), and sociodemographic variables. For this analysis, two groups were formed: men who had taken the HIV test in the past with negative or unknown results (Group A) and men who had not taken the test (Group B). The proportions of men who intended to take the test in the next year were 84.8% and 53.3% for groups A and B, respectively. For both groups, logistic regression indicated that the most important factors explaining intention were attitudes toward taking the test and perceived behavioral control. Additional variables specific to each group also contributed to explain intention. Thus, to enhance test-seeking among this population requires a consistent program of health education and facilitative policies.

Sexual risk and HIV-testing behaviour by gay and bisexual men in Canada

Behavioural epidemiology is an important aspect of HIV research, particularly among marginalized populations where measurement of rates of infection have not been conducted. This Canadian study provides a country-wide analysis of the characteristics and behaviours of gay and bisexual men, and examines the influence of geographic, socio-demographic and lifestyle influences on sexual behaviour and test-seeking. A purposive sample of 4,803 men was recruited through gay-identified venues. In order to provide national representation seven sampling strata were defined. Data were collected by self-completed questionnaire. A three-level hierarchical logistic regression analysis is used to model two behaviours, unprotected anal intercourse and test-seeking. The results showed that, nationally, 22.9% of respondents reported at least one episode of unprotected anal intercourse in the previous 3 months, and 63% had been tested. Characteristics and behaviours of men varied across the country. Geographic differences appear to be less important in explaining unprotected anal intercourse than test-seeking. In conclusion, policy, programmes and social environment appear to exert an important influence on test-seeking, whereas cultural and psychosocial dimensions appear to have a greater influence on sexual behaviour.

Comparison of saliva and blood for human immunodeficiency virus prevalence testing

Testing saliva for the detection of human immunodeficiency virus (HIV) antibodies has many potential advantages for epidemiologic surveillance. A commercial ELISA kit and a standardized in-house immunoblot (IB) system were slightly modified to enhance antibody detection in saliva. Frozen saliva specimens from Toronto Sexual Contact Study participants (including sequential saliva specimens collected during seroconversion) were tested as were fresh saliva samples collected from a population of street-based intravenous drug users (IVDUs). HIV antibody results on saliva were compared with HIV serostatus determined by ELISA and IB on serum or dried blood spots. The overall sensitivity was 98.3% (117/119) for the kit and 99.2% (118/119) for IB; the specificity was 100% (429/429). In the IVDU population, compliance in the voluntary submission of specimens increased from 69% agreeing to provide blood samples to 89% agreeing to provide blood, saliva, or both. Saliva specimens can be easily collected under difficult field conditions with minimal training and provide a valuable alternative to testing blood for HIV-seroprevalence studies.

Assessment of generalized lymphadenopathy in AIDS research: the degree of clinical agreement

The degree of clinical agreement amongst different physicians on the presence or absence of generalized lymphadenopathy was assessed in 32 randomly selected participants from a prospective study of male sexual contacts of men with AIDS or an AIDS-related condition (ARC). Three physicians completed the same standard examination that was developed for the main project and conducted the examination of the anatomic regions in the same order on each person, at approximately the same time, and in random order. One physician (Doctor A) was the physician responsible for conducting examinations on the main cohort from which these participants were selected. Intra-observer agreement was assessed by comparing Doctor A's examinations on these participants with those he had recently conducted within a one and a half month period in the main study. Acceptable levels of intra-observer agreement (kappa = 0.72) and interobserver agreement (kappa = 0.66) were demonstrated for the presence or absence of generalized lymphadenopathy for Doctor A and Doctor B, a physician who periodically replaced Doctor A in the main project. Agreement between Doctors A, B, and C, was less satisfactory (kappa of 0.45 and 0.39, respectively). Doctor C was the least experienced with the standardized examination. However, during the progress of this study, agreement between the three doctors improved (kappa values for the latter 16 participants ranged from 0.60 to 0.86) suggesting that experience with the criteria and the standardization of the examination may enhance agreement.(ABSTRACT TRUNCATED AT 250 WORDS)
