RESUMO

OBJECTIVES: In the UK, people of black ethnicity experience a disproportionate burden of HIV and STI. We aimed to assess the association of ethnicity with sexual behaviour and sexual health among women and heterosexual men attending genitourinary medicine (GUM) clinics in England. METHODS: The Attitudes to and Understanding of Risk of Acquisition of HIV is a cross-sectional, self-administered questionnaire study of HIV negative people recruited from 20 GUM clinics in England, 2013-2014. Modified Poisson regression with robust SEs was used to calculate adjusted prevalence ratios (aPR) for the association between ethnicity and various sexual risk behaviours, adjusted for age, study region, education and relationship status. RESULTS: Questionnaires were completed by 1146 individuals, 676 women and 470 heterosexual men. Ethnicity was recorded for 1131 (98.8%) participants: 550 (48.6%) black/mixed African, 168 (14.9%) black/mixed Caribbean, 308 (27.2%) white ethnic groups, 105 (9.3%) other ethnicity. Compared with women from white ethnic groups, black/mixed African women were less likely to report condomless sex with a non-regular partner (aPR (95% CI) 0.67 (0.51 to 0.88)), black/mixed African and black/mixed Caribbean women were less likely to report two or more new partners (0.42 (0.32 to 0.55) and 0.44 (0.29 to 0.65), respectively), and black/mixed Caribbean women were more likely to report an STI diagnosis (1.56 (1.00 to 2.42)). Compared with men from white ethnic groups, black/mixed Caribbean men were more likely to report an STI diagnosis (1.91 (1.20 to 3.04)), but did not report risk behaviours more frequently. Men and women of black/mixed Caribbean ethnicity remained more likely to report STI history after adjustment for sexual risk behaviours. DISCUSSION: Risk behaviours were reported less frequently by women of black ethnicity; however, history of STI was more prevalent among black/mixed Caribbean women. In black/mixed Caribbean men, higher STI history was not explained by ethnic variation in reported risk behaviours. The association between STI and black/mixed Caribbean ethnicity remained after adjustment for risk behaviours.

RESUMO

OBJECTIVE: HIV transmission is ongoing among men who have sex with men (MSM) in the UK. Sex without a condom (condomless sex, CLS) is the main risk factor. We investigated the prevalence of and factors associated with types of CLS. METHODS: Cross-sectional questionnaire study in UK HIV clinics in 2011/2012 (ASTRA). MSM diagnosed with HIV for ≥3 months reported on anal and vaginal sex, CLS with HIV-serodifferent partners (CLS-D) and CLS with HIV-seroconcordant (CLS-C) partners in the previous 3 months. Mutually exclusive sexual behaviours were as follows: (1) Higher HIV risk CLS-D (not on antiretroviral therapy (ART) or clinic-recorded viral load(VL) >50 c/mL), (2) Other CLS-D, (3) CLS-C without CLS-D, (4) Condom-protected sex only and (5) No anal or vaginal sex. Associations were examined of sociodemographic, HIV-related, lifestyle, and other sexual measures with the five categories of sexual behaviour. We examined the prevalence of higher HIV risk CLS-D incorporating (in addition to ART and VL) time on ART, ART non-adherence, and recent sexually transmitted infections (STIs). RESULTS: Among 2189 HIV-diagnosed MSM (87% on ART), prevalence of any CLS in the past 3 months was 38.2% (95% CI 36.2% to 40.4%) and that of any CLS-D was 16.3% (14.8%-17.9%). The five-category classification was as follows: (1) Higher HIV risk CLS-D: 4.2% (3.5% to 5.2%), (2) Other CLS-D: 12.1% (10.8% to 13.5%), (3) CLS-C without CLS-D: 21.9% (20.2% to 23.7%), (4) Condom-protected sex only: 25.4% (23.6% to 27.3%) and (5) No anal or vaginal sex: 36.4% (34.3% to 38.4%). Compared with men who reported condom-protected sex only, MSM who reported any CLS in the past 3 months had higher prevalence of STIs, chemsex-associated drug use, group sex, higher partner numbers, and lifetime hepatitis C. Prevalence of higher HIV risk CLS-D ranged from 4.2% to 7.5% according to criteria included. CONCLUSION: CLS was prevalent among HIV-diagnosed MSM, but CLS-D with higher HIV transmission risk was overall low. CLS-D is no longer the most appropriate measure of HIV transmission risk behaviour among people with diagnosed HIV; accounting for VL is important.

RESUMO

OBJECTIVES: UK guidance advises HIV-positive women to abstain from breast feeding. Although this eliminates the risk of postnatal vertical transmission of HIV, the impact of replacement feeding on mothers is often overlooked. This qualitative study examines, for the first time in the UK, decision-making about infant feeding among African women living with HIV. METHODS: Between 2010 and 2011, we conducted semistructured interviews with 23 HIV-positive African women who were pregnant or had recently given birth. We recruited participants from three HIV antenatal clinics in London. RESULTS: Women highlighted the cultural importance of breast feeding in African communities and the social pressure to breast feed, also describing fears that replacement feeding would signify their HIV status. Participants had significant concerns about physical and psychological effects of replacement feeding on their child and felt their identity as good mothers was compromised by not breast feeding. However, almost all chose to refrain from breast feeding, driven by the desire to minimise vertical transmission risk. Participants' resilience was strengthened by financial assistance with replacement feeding, examples of healthy formula-fed children and support from partners, family, peers and professionals. CONCLUSIONS: The decision to avoid breast feeding came at considerable emotional cost to participants. Professionals should be aware of the difficulties encountered by HIV-positive women in refraining from breast feeding, especially those from migrant African communities where breast feeding is culturally normative. Appropriate financial and emotional support increases women's capacity to adhere to their infant-feeding decisions and may reduce the emotional impact.

RESUMO

BACKGROUND: Little is known about retention in human immunodeficiency virus (HIV) care in HIV-positive women after pregnancy in the United Kingdom. We explored the association between loss to follow-up (LTFU) in the year after pregnancy, maternal place of birth and duration of UK residence, in HIV-positive women in England, Wales, and Northern Ireland. METHODS: We analyzed combined data from 2 national data sets: the National Study of HIV in Pregnancy and Childhood; and the Survey of Prevalent HIV Infections Diagnosed, including pregnancies in 2000 to 2009 in women with diagnosed HIV. Logistic regression models were fitted with robust standard errors to estimate adjusted odds ratios (AOR). RESULTS: Overall, 902 of 7211 (12.5%) women did not access HIV care in the year after pregnancy. Factors associated with LTFU included younger age, last CD4 in pregnancy of 350 cells/µL or greater and detectable HIV viral load at the end of pregnancy (all P<0.001). On multivariable analysis, LTFU was more likely in sub-Saharan Africa-born (SSA-born) women than white UK-born women (AOR, 2.17; 95% confidence interval, 1.50-3.14; P<0.001). The SSA-born women who had migrated to the UK during pregnancy were 3 times more likely than white UK-born women to be lost to follow-up (AOR, 3.19; 95% confidence interval, 1.94-3.23; P<0.001). CONCLUSIONS: One in 8 HIV-positive women in England, Wales, and Northern Ireland did not return for HIV care in the year after pregnancy, with SSA-born women, especially those who migrated to the United Kingdom during pregnancy, at increased risk. Although emigration is a possible explanatory factor, disengagement from care may also play a role.

RESUMO

The ways in which couples communicate about microbicides is likely to influence microbicide uptake and usage. We collected quantitative data about whether women in a microbicide trial discussed microbicides with their partners and explored communication about microbicides during 79 in-depth-interviews with women enrolled in the trial and 17 focus-group discussions with community members. After 4 weeks in the trial, 60 % of 1092 women had discussed microbicides with their partners; in multivariate analysis, this was associated with younger age, clinic of enrolment and not living in households that owned cattle. After 52 weeks, 84 % of women had discussed microbicides; in multivariate analysis, this was associated with not living in households that owned cattle, not living in a household that relied on the cheapest water source, allocation to 0.5 % PRO2000 gel and consistent gel adherence. Qualitative findings highlighted that women in committed relationships were expected to discuss microbicides with their partners and preferred to use microbicides with their partner's knowledge. Women had different reasons for, and ways of, discussing microbicides and these were influenced by the couple's decision-making roles. Although there was tolerance for the use of microbicides without a partner's knowledge, the women who used microbicides secretly appeared to be women who were least able to discuss microbicides. In KwaZulu-Natal, socio-cultural norms informing sexual communication are amenable to microbicide introduction.

RESUMO

AIM: To examine epidemiological trends among heterosexual adults (≥15 years) in England, Wales, and Northern Ireland (E,W&NI) newly diagnosed as having HIV between 1992 and 2011, or seen for HIV care in 2011. METHODS: Trend analyses of heterosexual adults newly diagnosed as having HIV in E,W&NI in 1992 to 2011 was performed, as well as univariate and multivariate analyses examining the late diagnosis of HIV, integration into care, AIDS, uptake of antiretroviral therapy, and mortality in 2002 to 2011. Data are as reported to the national HIV and AIDS Reporting System. RESULTS: The number of heterosexual adults newly diagnosed as having HIV in E,W&NI increased steadily between 1992 (731) and 2004 (4676), before declining (2631 in 2011). Nonetheless, in 2011, heterosexuals accounted for 49% (2631/5423) of all newly diagnosed adults in E,W&NI. Of 38,228 heterosexual adults as having HIV between 2002 and 2011, 72% were black African, of whom 99% were born abroad. Over the decade, there was an increase in the percentage of HIV diagnosed heterosexuals integrated into care within 28 days of diagnosis (61%-78%) and in receipt of antiretroviral therapy within 1 year of diagnosis (45%-52%) and a decline in the percentage with AIDS (16%-7%; all, P < 0.01). Late HIV diagnoses (CD4 <350 mm) among heterosexuals exceeded 60% in all years. CONCLUSIONS: Our analyses highlight the impact of migration on the epidemiology of heterosexually acquired HIV in E,W&NI. Although there was evidence of an improvement in clinical care over time, continued high rates of late diagnosis suggest that current testing policies are failing among heterosexuals.

RESUMO

Post-coital intravaginal cleansing (IVC) could counteract the protective effect of a vaginal microbicide. IVC less than 1 h after sex is discouraged in most microbicide trials. During a microbicide trial in KwaZulu-Natal, we collected quantitative data on post-coital IVC. We discussed IVC during in-depth-interviews (IDIs) and focus-group discussions (FGDs) with women enrolled in the trial, and during FGDs with community members. Nearly one-third (336/1,143) of women reported IVC less than an hour after sex. In multivariate analysis, post-coital IVC was associated with younger age, larger household size, greater sexual activity, consistent gel use, and clinic of enrolment. During IDIs and FGDs, respondents described post-coital IVC as a common hygiene practice motivated by the need to remove semen, vaginal fluids and sweat, although this practice may be amenable to change in the context of microbicide use. We need to consider strategies for influencing post-coital IVC practices in future microbicide trials and delivery programmes.

RESUMO

BACKGROUND: We did a meta-analysis to assess factors associated with disparities in HIV infection in black men who have sex with men (MSM) in Canada, the UK, and the USA. METHODS: We searched Embase, Medline, Google Scholar, and online conference proceedings from Jan 1, 1981, to Dec 31, 2011, for racial comparative studies with quantitative outcomes associated with HIV risk or HIV infection. Key words and Medical Subject Headings (US National Library of Medicine) relevant to race were cross-referenced with citations pertinent to homosexuality in Canada, the UK, and the USA. Data were aggregated across studies for every outcome of interest to estimate overall effect sizes, which were converted into summary ORs for 106,148 black MSM relative to 581,577 other MSM. FINDINGS: We analysed seven studies from Canada, 13 from the UK, and 174 from the USA. In every country, black MSM were as likely to engage similarly in serodiscordant unprotected sex as other MSM. Black MSM in Canada and the USA were less likely than other MSM to have a history of substance use (odds ratio, OR, 0·53, 95% CI 0·38-0·75, for Canada and 0·67, 0·50-0·92, for the USA). Black MSM in the UK (1·86, 1·58-2·18) and the USA (3·00, 2·06-4·40) were more likely to be HIV positive than were other MSM, but HIV-positive black MSM in each country were less likely (22% in the UK and 60% in the USA) to initiate combination antiretroviral therapy (cART) than other HIV-positive MSM. US HIV-positive black MSM were also less likely to have health insurance, have a high CD4 count, adhere to cART, or be virally suppressed than were other US HIV-positive MSM. Notably, despite a two-fold greater odds of having any structural barrier that increases HIV risk (eg, unemployment, low income, previous incarceration, or less education) compared with other US MSM, US black MSM were more likely to report any preventive behaviour against HIV infection (1·39, 1·23-1·57). For outcomes associated with HIV infection, disparities were greatest for US black MSM versus other MSM for structural barriers, sex partner demographics (eg, age, race), and HIV care outcomes, whereas disparities were least for sexual risk outcomes. INTERPRETATION: Similar racial disparities in HIV and sexually transmitted infections and cART initiation are seen in MSM in the UK and the USA. Elimination of disparities in HIV infection in black MSM cannot be accomplished without addressing structural barriers or differences in HIV clinical care access and outcomes. FUNDING: None.

RESUMO

The objective was to examine the association between circumcision status and self-reported HIV infection among men who have sex with men (MSM) in Britain who predominantly or exclusively engaged in insertive anal intercourse. In 2007-2008, a convenience sample of MSM living in Britain was recruited through websites, in sexual health clinics, bars, clubs, and other venues. Men completed an online survey which included questions on circumcision status, HIV testing, HIV status, sexual risk behavior, and sexual role for anal sex. The analysis was restricted to 1,521 white British MSM who reported unprotected anal intercourse in the previous 3 months and who said they only or mostly took the insertive role during anal sex. Of these men, 254 (16.7 %) were circumcised. Among men who had had a previous HIV test (n = 1,097), self-reported HIV seropositivity was 8.6 % for circumcised men (17/197) and 8.9 % for uncircumcised men (80/900) (unadjusted odds ratio [OR], 0.97; 95 % confidence interval [95 % CI], 0.56, 1.67). In a multivariable logistic model adjusted for known risk factors for HIV infection, there was no evidence of an association between HIV seropositivity and circumcision status (adjusted OR, 0.79; 95 % CI, 0.43, 1.44), even among the 400 MSM who engaged exclusively in insertive anal sex (adjusted OR, 0.84; 95 % CI, 0.25, 2.81). Our study provides further evidence that circumcision is unlikely to be an effective strategy for HIV prevention among MSM in Britain.

RESUMO

OBJECTIVE: To compare the experiences of ethnic minority and white British men who have sex with men (MSM) who attend NHS sexual health clinics in Britain. METHODS: In 2007-2008, a national sample of MSM living in Britain was recruited through websites, in sexual health clinics, bars, clubs and other venues. Men completed an online survey, which included questions about their experience of attending an NHS sexual health clinic. RESULTS: Analysis is restricted to 363 ethnic minority MSM and 4776 white British MSM who had attended an NHS sexual health clinic in the 12 months before the survey. Compared with white British men, men from an Indian, Pakistani or Bangladeshi background were more likely to be very anxious about attending the clinic (adjusted OR (aOR) 2.58, 95% CI 1.63 to 4.07), express concerns about being overheard at reception (aOR 1.68, 95% CI 1.10 to 2.58), be uncomfortable in the waiting area (aOR 2.08, 95% CI 1.35 to 3.22) or be afraid that people in their community would find out that they have sex with men (aOR 7.70, 95% CI 4.49 to 13.22). The adjusted ORs for being afraid that people in their community would find out that they have sex with men were also elevated for black Caribbean, black African, Chinese and other Asian men. CONCLUSION: Sexual health clinics should be aware that some ethnic minority MSM, particularly those from an Indian, Pakistani or Bangladeshi background, have heightened concerns about clinic attendance and confidentiality compared with white British MSM.

RESUMO

OBJECTIVE: To examine human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) from different ethnic and migrant groups living in Britain. METHODS: In 2007-2008, a diverse national sample of MSM living in Britain was recruited through Web sites, in sexual health clinics, bars, clubs, and other venues. Men completed an online survey that included questions on HIV testing, HIV status, and sexual behavior. RESULTS: Nine hundred and ninety-one ethnic minority MSM, 207 men born in Central or Eastern Europe (CEE), 136 men born in South or Central America, and 11,944 white British men were included in the analysis. Self-reported HIV seropositivity was low for men of South Asian, Chinese, and "other Asian" ethnicity (range, 0.0%-5.8%) and for men born in CEE (4.5%) but elevated for men born in South or Central America (18.7%), compared with white British men (13.1%) (P < 0.001). There were no significant differences between these groups in high-risk sexual behavior (P = 0.8). After adjusting for confounding factors in a multivariable model, substantial differences in the odds of HIV infection remained for South Asian and Chinese MSM as well as for migrants from CEE, but not for other groups, compared with white British men; for example, South Asian men, adjusted odds ratio 0.43, 95% confidence interval 0.23, 0.79, P = 0.007. CONCLUSION: There were marked differences in self-reported HIV seropositivity between ethnic minority, key migrant, and white British MSM in this study but not in high-risk sexual behavior. This highlights the importance of health promotion targeting MSM from all ethnic and migrant groups in Britain.

RESUMO

We conducted a cross-sectional online survey of men who have sex with men (MSM) living in Britain in 2007-2008 to examine sexual mixing among ethnic minority MSM. The sample comprised 115 black, 112 South Asian, 47 Chinese and 4,434 white MSM who reported unprotected anal intercourse (UAI) in the previous 3 months. In each ethnic minority group, MSM were three times more likely to report UAI with a partner of the same ethnicity than would be expected by chance alone (χ(2) > 8.43, p < 0.05). Nonetheless, most (>80 %) ethnic minority MSM reported UAI with men from an ethnic group other than their own. In multivariable analysis there was statistical evidence that, compared with white British MSM, self-reported HIV seropositivity remained low for South Asian and Chinese MSM after adjusting for UAI with partners of the same ethnicity (e.g. South Asian MSM, adjusted odds ratio 0.35, 95 % CI 0.19-0.66). This analysis suggests that differences in self-reported HIV seropositivity between ethnic minority and white MSM in Britain cannot be explained by sexual mixing with partners from the same ethnic group.

RESUMO

UK and Ireland guidelines state that all pregnant women should have their first antenatal care appointment by 13 weeks of pregnancy (antenatal booking). We present the results of an analysis looking at the association between maternal ethnicity and late antenatal booking in HIV-positive women in the UK and Ireland. We analysed data from the National Study of HIV in Pregnancy and Childhood (NSHPC). We included all pregnancies in women who were diagnosed with HIV before delivery and had an estimated delivery date between 1 January 2008 and 31 December 2009. Late booking was defined as antenatal booking at 13 weeks or later. The baseline reference group for all analyses comprised women of "white" ethnicity. Logistic regression models were fitted to estimate adjusted odds ratios (AOR). There were 2721 eligible reported pregnancies; 63% (1709) had data available on antenatal care booking date. In just over 50% of pregnancies (871/1709), the antenatal booking date was ≥13 weeks of pregnancy (i.e., late booking). Women diagnosed with HIV during the current pregnancy were more likely to present for antenatal care late than those previously diagnosed (59.1% vs. 47.5%, p<0.001). Where women knew their HIV status prior to becoming pregnant, the risk of late booking was raised for those of African ethnicity (AOR 1.80; 95% confidence interval (CI) 1.14, 2.82; p=0.011). In women diagnosed with HIV during pregnancy, the risk of late booking was also higher for women of African ethnicity (AOR 2.98: 95% CI 1.45, 6.11; p=0.003) and for women of other black ethnicity (AOR 3.74: 95% CI 1.28, 10.94; p=0.016). Overall, women of African or other black ethnicity were more likely to book late for antenatal care compared with white women, regardless of timing of diagnosis. This may have an adverse effect on maternal and infant outcomes, including mother-to-child transmission of HIV.

RESUMO

BACKGROUND: The number of reported pregnancies in women with diagnosed HIV in the UK increased from 80 in 1990 to over 1400 in 2010; the majority were among women born in sub-Saharan Africa. There is a paucity of research on how social adversity impacts upon pregnancy in HIV positive women in the UK; furthermore, little is known about important outcomes such as treatment uptake and return for follow-up after pregnancy. The aim of this study was to examine pregnancy in African women living with HIV in the UK. METHODS AND DESIGN: This was a two phase mixed methods study. The first phase involved analysis of data on approximately 12,000 pregnancies occurring between 2000 and 2010 reported to the UK's National Study of HIV in Pregnancy and Childhood (NSHPC). The second phase was based in London and comprised: (i) semi-structured interviews with 23 pregnant African women living with HIV, 4 health care professionals and 2 voluntary sector workers; (ii) approximately 90 hours of ethnographic fieldwork in an HIV charity; and (iii) approximately 40 hours of ethnographic fieldwork in a Pentecostal church. DISCUSSION: We have developed an innovative methodology utilising epidemiological and anthropological methods to explore pregnancy in African women living with HIV in the UK. The data collected in this mixed methods study are currently being analysed and will facilitate the development of appropriate services for this group.

RESUMO

OBJECTIVES: To examine changes in the sexual behavior of London gay men between 1998 and 2008. METHODS: Gay men using London gyms were surveyed annually between 1998 and 2005, and again in 2008 (n=6064; range, 482-834 per year). Information was collected on human immunodeficiency virus (HIV) status of the respondent, unprotected anal intercourse (UAI) in the previous 3 months, type (main or casual) and HIV status of partner for UAI. Nonconcordant UAI (ncUAI) was defined as UAI with a partner of unknown or discordant HIV status. Concordant UAI (cUAI) was defined as UAI with a partner of the same HIV status ("serosorting"). RESULTS: Between 1998 and 2008, the percentage of men reporting UAI increased from 24.3% to 36.6% (P=0.07). This overall increase concealed important differences between nonconcordant and concordant UAI. While the percentage of men engaging in cUAI increased steadily between 1998 and 2008 (9.8%, 20.8%; P=0.01), the percentage reporting ncUAI increased between 1998 and 2001 (14.5%, 23.7%; P<0.001), decreased between 2001 and 2005 (23.7%, 15.6%; P<0.001), and then leveled off between 2005 and 2008 (15.6%, 15.7%; P=0.2). However, the percentage of men reporting ncUAI with a main partner increased between 2005 and 2008 for HIV-positive men (2.5%, 8.1%; P<0.05) and HIV negative men (2.1%, 5.5%; P=0.06). While the percentage of HIV negative men who reported cUAI with a main partner (i.e., serosorting) increased between 1998 and 2008 (12.4%, 21.1%; P<0.05), less than half established seroconcordance by testing together. CONCLUSIONS: The patterns of sexual behavior among London's gay men between 1998 and 2008 were dynamic and complex. Our data suggest that HIV risk with a main partner and HIV testing among couples should be given greater priority by health promotion programmes.

RESUMO

AIM: To assess the extent to which human immunodeficiency virus (HIV)-diagnosed adults attending HIV-services in England, Wales, and Northern Ireland are lost to follow-up or attend services intermittently. METHODS: A cohort of HIV-diagnosed adults was created by linking records across the 1998 to 2007 national annual Survey of Prevalent HIV Infections Diagnosed. The records were also linked to the national HIV and acquired immune deficiency syndrome New Diagnoses Database (n = 61,495) and to Office for National Statistics death records. Patterns of HIV-service attendance were analyzed. RESULTS: On average, 90% of adults attending HIV-services in any one year attended the following year. Nearly 5% of adults attending services in any one year were lost to follow-up, a further 4% subsequently attended services intermittently, whereas less than 2% died. Cumulatively, 19% of adults seen for HIV care between 1998 and 2006 were lost to follow-up by the end of 2007. Factors associated with loss to follow-up included being the following: female; aged 15 to 34 years; black-African or "other" ethnicity; not on antiretroviral therapy; recently diagnosed; and infected outside the United Kingdom. CONCLUSIONS: Although the majority of HIV-diagnosed adults in England, Wales, and Northern Ireland attended HIV-services regularly, cumulatively nearly 1 in 5 adults were lost to follow-up between 1998 and 2007. Innovative strategies focusing on those most likely to drop out of regular care should be developed to maintain regular service engagement and to ensure optimal care.

RESUMO

OBJECTIVES: To explore attitudes toward circumcision among men who have sex with men (MSM) in London and the feasibility of conducting research into circumcision and HIV prevention in this population. METHODS: A convenience sample of MSM visiting central London gyms completed a confidential, self-administered questionnaire between May and June 2008. Information was collected on participants' demographic characteristics, self-reported HIV status, sexual behavior, circumcision status, attitudes toward circumcision, and willingness to participate in research on circumcision and HIV prevention. RESULTS: Of 653 MSM, 29.0% reported that they were circumcised. Overall, HIV prevalence was 23.3%; this did not differ significantly between circumcised and uncircumcised men (18.6% vs. 25.2%, respectively; adjusted odds ratio 0.79, 95% confidence interval: 0.50-1.26). A similar proportion of circumcised and uncircumcised men reported unprotected anal intercourse in the previous 3 months (38.8% vs. 36.7%, adjusted odds ratio 1.06, 95% confidence interval: 0.72-1.55). Uncircumcised men were less likely to think that there were benefits of circumcision than circumcised men (31.2% vs. 65.4, P < 0.001). Only 10.3% of uncircumcised men said that they would be willing to participate in research on circumcision as an HIV prevention strategy. CONCLUSIONS: Most uncircumcised MSM in this London survey were unwilling to participate in research on circumcision and HIV prevention. Only a minority of uncircumcised men thought that there were benefits of circumcision. It is unlikely that circumcision would be a feasible strategy for HIV prevention among MSM in London.

RESUMO

PURPOSE OF REVIEW: Antiretroviral treatment means that an increasing number of men who have sex with men (MSM) are living with HIV. The present review focuses on continuing transmission of HIV, risk factors for HIV infection in HIV-negative MSM, risk behaviour and risk reduction interventions among HIV-positive MSM, sexually transmitted infections, HIV and ageing and new and emerging populations of MSM communities. RECENT FINDINGS: Transmission of HIV infection continues in populations of MSM; transmission may be particularly high from main partners. Serosorting offers limited protection against HIV infection for HIV-negative MSM; negotiated safety and strategic positioning may be partially protective. For HIV-positive men, serosorting is a strategy to prevent HIV transmission, but has contributed to high rates of new non-HIV sexually transmitted infections. Sexual networks are important to the understanding of emerging sexually transmitted infections; ageing brings a new dimension to research on HIV. SUMMARY: Strategies other than exclusive condom use have emerged in communities of MSM to reduce the risk of HIV transmission, including serosorting and strategic positioning. 'Combination prevention' - using social structural, behavioural and biomedical approaches in tandem - could reduce the risk of HIV transmission, and may be particularly suited to HIV-positive MSM.

RESUMO

BACKGROUND: Used in conjunction with biological surveillance, behavioural surveillance provides data allowing for a more precise definition of HIV/STI prevention strategies. In 2008, mapping of behavioural surveillance in EU/EFTA countries was performed on behalf of the European Centre for Disease prevention and Control. METHOD: Nine questionnaires were sent to all 31 member States and EEE/EFTA countries requesting data on the overall behavioural and second generation surveillance system and on surveillance in the general population, youth, men having sex with men (MSM), injecting drug users (IDU), sex workers (SW), migrants, people living with HIV/AIDS (PLWHA), and sexually transmitted infection (STI) clinics patients. Requested data included information on system organisation (e.g. sustainability, funding, institutionalisation), topics covered in surveys and main indicators. RESULTS: Twenty-eight of the 31 countries contacted supplied data. Sixteen countries reported an established behavioural surveillance system, and 13 a second generation surveillance system (combination of biological surveillance of HIV/AIDS and STI with behavioural surveillance). There were wide differences as regards the year of survey initiation, number of populations surveyed, data collection methods used, organisation of surveillance and coordination with biological surveillance. The populations most regularly surveyed are the general population, youth, MSM and IDU. SW, patients of STI clinics and PLWHA are surveyed less regularly and in only a small number of countries, and few countries have undertaken behavioural surveys among migrant or ethnic minorities populations. In many cases, the identification of populations with risk behaviour and the selection of populations to be included in a BS system have not been formally conducted, or are incomplete. Topics most frequently covered are similar across countries, although many different indicators are used. In most countries, sustainability of surveillance systems is not assured. CONCLUSION: Although many European countries have established behavioural surveillance systems, there is little harmonisation as regards the methods and indicators adopted. The main challenge now faced is to build and maintain organised and functional behavioural and second generation surveillance systems across Europe, to increase collaboration, to promote robust, sustainable and cost-effective data collection methods, and to harmonise indicators.

RESUMO

BACKGROUND: Men who have sex with men (MSM) remain the group most at risk of acquiring HIV infection in Britain. HIV prevalence appears to vary widely between MSM from different ethnic minority groups in this country for reasons that are not fully understood. The aim of the MESH project was to examine in detail the sexual health of ethnic minority MSM living in Britain. METHODS/DESIGN: The main objectives of the MESH project were to explore among ethnic minority MSM living in Britain: (i) sexual risk behaviour and HIV prevalence; (ii) their experience of stigma and discrimination; (iii) disclosure of sexuality; (iv) use of, and satisfaction with sexual health services; (v) the extent to which sexual health services (for treatment and prevention) are aware of the needs of ethnic minority MSM.The research was conducted between 2006 and 2008 in four national samples: (i) ethnic minority MSM living in Britain; (ii) a comparison group of white British MSM living in Britain; (iii) NHS sexual health clinic staff in 15 British towns and cities with significant ethnic minority communities and; (iv) sexual health promotion/HIV prevention service providers. We also recruited men from two "key migrant" groups living in Britain: MSM born in Central or Eastern Europe and MSM born in Central or South America.Internet-based quantitative and qualitative research methods were used. Ethnic minority MSM were recruited through advertisements on websites, in community venues, via informal networks and in sexual health clinics. White and "key migrant" MSM were recruited mostly through Gaydar, one of the most popular dating sites used by gay men in Britain. MSM who agreed to take part completed a questionnaire online. Ethnic minority MSM who completed the online questionnaire were asked if they would be willing to take part in an online qualitative interview using email.Service providers were identified through the British Association of Sexual Health and HIV (BASHH) and the Terrence Higgins Trust (THT) CHAPS partnerships. Staff who agreed to take part were asked to complete a questionnaire online.The online survey was completed by 1241 ethnic minority MSM, 416 men born in South and Central America or Central and Eastern Europe, and 13,717 white British MSM; 67 ethnic minority MSM took part in the online qualitative interview. In addition 364 people working in sexual health clinics and 124 health promotion workers from around Britain completed an online questionnaire. DISCUSSION: The findings from this study will improve our understanding of the sexual health and needs of ethnic minority MSM in Britain.
