Risk for HIV infection among bisexual men seeking HIV-prevention services and risks posed to their female partners.

The present study interviewed gay (n = 473) and bisexual men (n = 146) as part of an HIV prevention program and investigated social cognitive factors associated with HIV risk. Results indicated that HIV risk in homosexual men was associated with sexual openness and connections to gay communities, factors not associated with risk for bisexual men. Compared with men at lower risk, those who practiced high-risk sex scored lower on measures of perceived safer sex norms, safer sex self-efficacy, and social skills. Bisexual men with primary female partners often had not disclosed their bisexuality to female partners (75%), and 64% had not modified their behavior to protect female partners. Bisexual men who engage in high-risk behaviors therefore pose a risk to female partners who may be unaware of their involvement with men.

Lesbian and bisexual health care.

OBJECTIVE: To explore lesbian and bisexual women's experiences with their family physicians to learn about barriers to care and about how physicians can provide supportive care. DESIGN: Qualitative study that was part of a larger study of lesbian and bisexual women's health care. SETTING: The province of Nova Scotia, both urban and rural counties. PARTICIPANTS: Ninety-eight self-identified lesbian or bisexual women who volunteered through snowball sampling. Women were interviewed by lesbian, bisexual, or heterosexual female interviewers. METHOD: Semistructured, audiotaped, face-to-face interviews, exploring questions about demographic information, sexual orientation, general health care patterns, preferences for health care providers, disclosure issues, health care information, access issues, and important health care services. Transcription of audiotapes of interviews was followed by content, thematic, and discourse analyses. Thematic analysis is reported in this paper. MAIN OUTCOME FINDINGS: Three themes important for family physicians emerged: the importance of being gay positive, barriers to care, and strategies for providing appropriate care. CONCLUSIONS: Family physicians are in a pivotal position to ensure supportive care for lesbian and bisexual women. Physicians need to recognize barriers to care and to use gay-positive strategies, paying attention to self-education, health history, and clinic environment.

Trends and predictors of human immunodeficiency virus antibody testing by homosexual and bisexual adolescent males, 1989-1994.

OBJECTIVE: To identify temporal trends and predictors of human immunodeficiency virus (HIV) antibody testing in homosexual and bisexual youth, using the Health Belief Model as a conceptual framework. DESIGN: Cross-sectional survey. SUBJECTS: Five hundred one male volunteers, 13 to 21 years old, self-identified as homosexual, bisexual, or as having sex with men, were enrolled from June 1, 1989, to May 30, 1994. METHODS: Structured reviews and written instruments, including measures of perceived susceptibility to and severity of HIV disease, benefits and barriers to testing, and cues to action. Based on significant (P < .001) bivariate association, variables were selected for forward stepwise logistic regression analysis. OUTCOME MEASURES: Self-reported HIV antibody testing. RESULTS: Forty-five percent of the subjects had undergone HIV antibody testing, with no significant differences between annual cohorts. Predictors of testing were having discussed same-sex feelings or experiences with a physician or counselor, a history of unprotected receptive anal intercourse, substance abuse, younger age at self-identification as bisexual or homosexual, ever having had a steady male partner, having many friends who understand sexual orientation, living away from family, and older age. CONCLUSIONS: Testing practices did not change significantly across time. Human immunodeficiency virus testing was related to age, risky behaviors, living situation, bisexual or homosexual acculturation, and contacts with health professionals, corresponding to Health Belief/Model dimensions of perceived susceptibility, barriers, and cues to action.

The clinical effectiveness and cost-effectiveness of screening for anal squamous intraepithelial lesions in homosexual and bisexual HIV-positive men.

CONTEXT: Homosexual and bisexual men infected with human immunodeficiency virus (HIV) are at increased risk for human papillomavirus-related anal neoplasia and anal squamous cell carcinoma (SCC). OBJECTIVE: To estimate the clinical benefits and cost-effectiveness of screening HIV-positive homosexual and bisexual men foranal squamous intraepithelial lesions (ASIL) and anal SCC. DESIGN: Cost-effectiveness analysis performed from a societal perspective that used reference case recommendations from the Panel on Cost-Effectiveness in Health and Medicine. A state-transition Markov model was developed to calculate lifetime costs, life expectancy, and quality-adjusted life expectancy for no screening vs several screening strategies for ASIL and anal SCC using anal Papanicolaou (Pap) testing at different intervals. Values for incidence, progression, and regression of anal neoplasia; efficacy of screening and treatment; natural history of HIV; health-related quality of life; and costs were obtained from the literature. SETTING AND PARTICIPANTS: Hypothetical cohort of homosexual and bisexual HIV-positive men living in the United States. MAIN OUTCOME MEASURES: Life expectancy, quality-adjusted life expectancy, quality-adjusted years of life saved, lifetime costs, and incremental cost-effectiveness ratio. RESULTS: Screening for ASIL increased quality-adjusted life expectancy at all stages of HIV disease. Screening with anal Pap tests every 2 years, beginning in early HIV disease (CD4 cell count >0.50 x 10(9)/L), resulted in a 2.7-month gain in quality-adjusted life expectancy for an incremental cost-effectiveness ratio of $13,000 per quality-adjusted life year saved. Screening with anal Pap tests yearly provided additional benefit at an incremental cost of $16,600 per quality-adjusted life year saved. If screening was not initiated until later in the course of HIV disease (CD4 cell count <0.50 x 10(9)/L), then yearly Pap test screening was preferred due to the greater amount of prevalent anal disease (cost-effectiveness ratio of less than $25,000 per quality-adjusted life year saved compared with no screening). Screening every 6 months provided little additional benefit over that of yearly screening. Results were most sensitive to the rate of progression of ASIL to anal SCC and the effectiveness of treatment of precancerous lesions. CONCLUSIONS: Screening HIV-positive homosexual and bisexual men for ASIL and anal SCC with anal Pap tests offers quality-adjusted life expectancy benefits at a cost comparable with other accepted clinical preventive interventions.

Hepatitis B and Delta virus infection among heterosexuals, homosexuals and bisexual men.

The hepatitis B virus (HBV) and hepatitis Delta virus (HDV) infection rates were estimated in patients attending a venereal disease outpatient clinic: 759 heterosexuals and 154 homosexual-bisexual men. The anti-HBc prevalence was higher in homo-bisexual men (68.8 per 100) than in heterosexuals (41.8 per 100), whereas HBsAg was roughly the same in the two groups (about 6 per 100). The anti-HBc prevalence rate among heterosexuals was higher than that estimated in hospital personnel from the same geographical area. A positive association between anti-HBc prevalence and present or past sexually transmitted diseases (STD) was found among homo-bisexual men. Anti-HBc was also positively associated with herpes simplex type 2 antibodies in both heterosexuals and homo-bisexual men. These data are consistent with the hypothesis that sexual behavior also plays a role in the spread of infection among heterosexuals. Ten of the 46 HBsAg-positive subjects were anti-HDV positive: 6 of the 36 heterosexuals and 4 of the 10 homosexuals. All HDV-positive subjects had present or past STDs. These findings suggest sexual transmission of HDV infection.

Alcohol use and stigmatized sexual practices of HIV seropositive gay and bisexual men.

HIV seropositive (HIV+) gay and bisexual men continue to report unprotected sexual practices. Although numerous research studies have examined the relationship between alcohol use and unsafe sex, few have examined this from a qualitative perspective. In this paper, we examined the impact of alcohol use on stigmatized sexual practices among HIV+ gay and bisexual men with alcohol-use disorders. An ethnically diverse sample (81% men of color) from the New York City metropolitan area was recruited from a variety of settings frequented by gay and bisexual men. Using a qualitative interview, contextual issues regarding sexual activities under the influence of alcohol were examined. Qualitative analysis revealed that alcohol use facilitates engagement in sexual practices that are perceived as stigmatic while sober. Interventions targeting alcohol use and unsafe sex should be sensitive to the role which alcohol plays in the sexual practices among HIV+ gay and bisexual men.

Dating violence among gay, lesbian, and bisexual adolescents: results from a community survey.

PURPOSE: To characterize the prevalence of dating violence experienced by gay, lesbian, bisexual (GLB), and heterosexual adolescents. METHODS: Self-report surveys were collected and analyzed from 521 adolescents at a GLB youth rally. Respondents were asked about dating violence, including types of abuse, threats of "outing," and gender of abuser. Multivariate logistic regression analyses were used to test group differences. RESULTS: Reports of dating violence were prevalent in all sexual orientation groups, and there were few statistically significant differences. Compared with heterosexuals and controlling for age, bisexual males had greater odds of reporting any type of abuse, and bisexual females had greater odds of experiencing sexual abuse. Controlling for age, lesbians had greater odds of being scared about their safety, compared with heterosexual females, and bisexuals were more likely to be threatened with outing, compared with gay males/lesbians. CONCLUSIONS: Overall, the prevalence of dating violence among GLB adolescents is similar to that of heterosexuals. Dating violence outreach and prevention efforts should be targeted to reach GLB adolescents.

The Mpowerment Project: community-building with young gay and bisexual men to prevent HIV1.

The Mpowerment Project is a community-level HIV prevention intervention for young gay and bisexual men ages 18-27. The program seeks to build a strong, supportive young gay and bisexual men's community where young gay and bisexual men nurture and protect each other, particularly with regard to HIV prevention. The program's theoretical framework draws from the areas of diffusion of innovations, community organizing, peer influence, and personal empowerment. The Mpowerment Project promotes a norm for safer sex through a variety of social, outreach and small group activities. The project is run by a "Core Group" of 12-15 young gay and bisexual men who, with volunteers, design and carry out all project activities. Implemented in 4 communities (Eugene, OR; Santa Barbara, CA; Albuquerque, NM; Austin, TX), the Mpowerment Project has proven to be effective in reducing high risk sex. This paper discusses the development and implementation of the program and various challenges encountered.

Sexual behaviors and risks among bisexually- and gay-identified young Latino men.

This research compares patterns of sexual behavior and sexual risk of bisexually- and gay-identified Latino young men who have sex with men (YMSM). Four hundred forty-one Latino YMSM were surveyed at community venues in New York City. Twenty-two percent of the sample identified as bisexual, and 78% identified as gay. Bisexually-identified men were more likely to report having had multiple male sex partners in the last 3 months and less likely to report being exclusively involved with a main male partner. They were also approximately 3 1/2 times more likely to report unprotected insertive anal intercourse at last sexual contact with a nonmain male partner and more likely to report being high at last contact with both main and nonmain male partners. Findings suggest that prevention programs need to address the particular sexual risk patterns of bisexually-identified Latino YMSM that place them at risk of both HIV infection and transmission.

Cigarette smoking among lesbians, gays, and bisexuals: how serious a problem? (United States).

INTRODUCTION: Population-based health surveys seldom assess sexual orientation, which results in the absence of a reliable measure of smoking among lesbians, gays, and bisexuals (LGB), a population perceived to have higher risks of tobacco-related diseases. This is the first study to compare the cigarette smoking rate of LGB with that of heterosexual individuals using a population-based sample with both male and female adults, and to identify which sub segments of LGB population are particularly burdened by tobacco use. METHODS: California Health Interview Survey (CHIS), a population-based telephone survey was used to assess smoking prevalence and its correlates among respondents. Of 44,606 respondents, 343 self-identified as lesbian; 593 self-identified as gay; and 793 identified themselves as bisexual (511 female and 282 male). Statistical analysis was performed using SAS and SUDAAN. RESULTS: Lesbians' smoking rate (25.3%), was about 70% higher than that of heterosexual women (14.9%) Gay men had a smoking prevalence of 33.2%, comparing to heterosexual men (21.3%). After controlling for demographic variables, logistic regression analysis showed that lesbians and bisexual women were significantly more likely to smoke compared with heterosexual women (OR = 1.95 and OR = 2.08, respectively). Gay men were also significantly more likely to smoke than heterosexual men (OR = 2.13; 95% CI = 1.66-2.73). Being 35-44-years-old, non-Hispanic White, and having low-education attainment and low-household income were common demographic predictors of cigarette smoking among LGB. CONCLUSION: Our study provides the strongest evidence to date that lesbians, bisexual females, and gay men had significantly higher cigarette smoking prevalence rates than their heterosexual counterparts.

Bacterial sexually transmitted infections in gay, lesbian, and bisexual adolescents: medical and public health perspectives.

Gay, lesbian, and bisexual adolescents, like all adolescents who engage in high-risk sexual behaviors, are at elevated risk for acquiring sexually transmitted infections (STIs). Personal sexual risk factors and issues related to access to care complicate the lives of youth who engage in same-gender sexual activity and who may or may not self-identify as gay, lesbian, or bisexual. Whereas epidemiologic rates of gonorrhea, chlamydia, and syphilis generally have trended downward in adolescents as a whole during the past 15 years, rates for these common reportable bacterial STIs have increased overall during recent years among men who have sex with men. This article focuses on bacterial STIs in youth with same-gender sexual activity. An understanding of trends among gay, lesbian, and bisexual youth remains incomplete, given the absence of consistent and uniform mechanisms for collecting data on sexual behaviors in adolescents and difficulties in associating these behaviors with reportable STIs. Special attention should be given to the screening, diagnosis, and treatment of bacterial STIs in those who engage in same-sex behavior, as new recommendations from the Centers for Disease Control and Prevention have been made available. It is critical that healthcare providers who work with adolescents be aware of the assortment of specific healthcare needs of gay, lesbian, and bisexual youth and address them appropriately in the clinical setting. Medical providers may be one of few true advocates for this often-marginalized adolescent population and have the power to have a positive influence on health promotion and education efforts.

Sexual identity development among gay, lesbian, and bisexual youths: consistency and change over time.

A longitudinal report of 156 gay, lesbian, and bisexual youths examined changes in sexual identity over time. Fifty-seven percent of the youths remained consistently self-identified as gay/lesbian, 18% transited from bisexual to gay/lesbian, and 15% consistently identified as bisexual over time. Although youths who consistently identified as gay/lesbian did not differ from other youths on time since experiencing sexual developmental milestones, they reported current sexual orientation and sexual behaviors that were more same-sex centered and they scored higher on aspects of the identity integration process (e.g., more certain, comfortable, and accepting of their same-sex sexuality, more involved in gay-related social activities, more possessing of positive attitudes toward homosexuality, and more comfortable with others knowing about their sexuality) than youths who transited to a gay/lesbian identity and youths who consistently identified as bisexual. Contrary to the hypothesis that females are more sexually fluid than males, female youths were less likely to change identities than male youths. The finding that youths who transited to a gay/lesbian identity differed from consistently gay/lesbian youths suggests that identity integration continues after the adoption of a gay/lesbian sexual identity.

Australian lesbian and bisexual women's health and social experiences of living with hepatitis C.

We recruited women in two Australian locations to complete a questionnaire on their health and social experiences of living with the hepatitis C virus (HCV). Among 462 respondents 9% identified themselves as lesbian and 14% as bisexual. Bisexuals were more disadvantaged than lesbians or heterosexuals on income, work status, home ownership, and level of education. Lesbians and bisexuals were less likely to be referred for HCV treatment and were more likely to report being treated negatively by any health professional. Lesbians and bisexuals experience HCV differently from one another and from heterosexuals. Their needs are not being met by women's health and HCV-specific services.

A demographic and health profile of gay and bisexual men in a large Canadian urban setting.

The purpose of this study was to provide both a population estimate and a socio-economic and health profile of gay and bisexual men living with HIV/AIDS in a large Canadian urban centre. A random telephone survey was used to determine the number of men in the study area over the age of 20 identifying as gay or bisexual and to characterize their health and socio-economic status. Out of a total of 1,176 completed interviews, 300 males described themselves as gay or bisexual. Projecting this figure on recent census data we estimated the number of men identifying as gay or bisexual in this region of downtown Vancouver, BC, at 5,100. Among these men we found an HIV prevalence rate of 16%, with those who reported a positive serostatus being less likely to be employed full time and more likely to earn less than $20,000 per year. In terms of clinical characteristics, HIV-positive men had a median CD4 cell count of 397 cells/mm(3) and a median viral load of less than 500 copies/ml. Eighty-three per cent of the HIV-positive respondents were on antiretroviral therapy and the median number of drugs taken by these men was three. In summary, random surveys of populations affected by this epidemic are important for policy makers, clinicians and persons caring for those with HIV/AIDS as they paint a clearer picture of who is being affected and help to identify areas where increased services are needed.

Assessing gay and bisexual men's outcome expectancies for sexual risk under the influence of alcohol and drugs.

Alcohol and substance use plays a complex role in sexual behavior among gay and bisexual men. Data from 779 gay and bisexual men who reported sex with a casual partner in the past 3 months were collected in November 2002 at two large lesbian, gay, and bisexual community events in New York City. Participants reporting any unprotected anal receptive or insertive sex scored significantly higher in outcome expectancies for sexual risk taking while using drugs or alcohol, as did HIV-positive men and men with a higher rate of lifetime sexually transmitted infections. Sexual compulsivity, romantic obsessions, drug use, unprotected anal receptive sex, and HIV serostatus successfully predicted outcome expectancies for sexual risk while under the influence. Therapists and other health and social service providers working with gay and bisexual men should explore the connection between sexual risk and being under the influence to uncover psychosocial mechanisms related to this phenomenon.

How many HIV infections cross the bisexual bridge? An estimate from the United States.

OBJECTIVE: Most heterosexual women with AIDS have been infected by male sex partners who acquired HIV via injecting drug use or sex with men. The contribution of bisexuality to heterosexual HIV however, has been poorly quantified. In this paper, we estimate the number of HIV infections that spread from the homosexual community to women who have sex with bisexual men. METHODS: We developed an HIV transmission model and assigned values to the model's parameters using data from a probability survey of US cities with a high risk of HIV. RESULTS: We estimated that these are about 400 HIV infections transmitted annually from HIV-infected bisexual men in high-risk cities to their female sex partners; two-thirds of these infections are transmitted to main female partners and one-third to casual partners. Uncertainties in the value of model parameters lead to variation in expected HIV infections mostly within the range 200 to 600, and for one parameter up to nearly 800. CONCLUSION: We conclude that transmission via bisexuality is a relatively minor component of the estimated 40,000 annual HIV infections in the USA.

Actual versus perceived HIV status, sexual behaviors and predictors of unprotected sex among young gay and bisexual men who identify as HIV-negative, HIV-positive and untested.

OBJECTIVES: To compare the prevalence and predictors of HIV sexual risk behavior among young gay and bisexual men who perceived themselves to be HIV-negative, HIV-positive, or who were untested. DESIGN: Population-based sample of young gay and bisexual men. METHODS: Using multi-stage probability sampling, 408 gay and bisexual men aged 18-29 years in San Francisco were recruited and interviewed, and blood samples for HIV-testing from 364 participants were obtained. RESULTS: HIV prevalence was 18.7%, although 25% of the men who were HIV-positive did not know it. Thirty-seven per cent reported engaging in unprotected anal intercourse during the past year, including 59% of the men who knew they were HIV-positive, 35% of the men who perceived themselves HIV-negative and 28% of the untested men. Logistic regressions found similar predictors of unprotected intercourse for HIV-negatives and HIV-positives, including sexual impulsivity, substance use, sexual enjoyment and communication problems. CONCLUSIONS: The high rates of unprotected intercourse, particularly among the HIV-positive men, attest to the urgent need for HIV-prevention interventions for young gay and bisexual men. The findings suggest that many of the important variables to target in interventions are similar for both HIV-positive and HIV-negative men.

Risk factors associated with HIV infection among young gay and bisexual men in Canada.

OBJECTIVE: To assess risk factors associated with HIV prevalence and incidence among gay and bisexual men in two prospective Canadian cohorts. METHODS: The Vanguard Project and the Omega Cohort are prospective cohort studies of gay and bisexual men ongoing in Vancouver and Montreal, respectively. For this analysis, baseline sociodemographic characteristics, sexual behavior, and substance use data from these two cohorts were combined. Assessment of risk factors for HIV seroprevalence and seroconversion were carried out using univariate and multivariate analysis. RESULTS: This analysis was based on 1373 gay and bisexual men aged 16 to 30 years. Men who were HIV-seropositive at baseline (n = 48) were more likely to report living in unstable housing, to have had less than a high school education, and to have been unemployed than those who were HIV-negative (n = 1325). HIV-positive men were also more likely to report having engaged in sexual risk behavior, including having had consensual sex at a younger age, having had at least 6 partners during the previous year, ever having been involved in the sex trade, and having engaged in unprotected receptive anal intercourse. With respect to substance use, HIV-positive men were more likely to report the use of crack, cocaine, heroin, and marijuana and to use injection drugs. Similarly, men who seroconverted during the course of the studies (n = 26) were more likely to report having less than a high school education and having lived in unstable housing at baseline. Compared with HIV-negative men, men who seroconverted were more likely to report ever having been involved in the sex trade and engaging in unprotected receptive anal intercourse. Reports of cocaine use and injection drug use were also significantly higher for men who seroconverted compared with HIV-negative men. CONCLUSIONS: Our data indicate that HIV-positive gay and bisexual men are more likely to be living in unstable conditions and to report more risky sexual and substance use behaviors than HIV-negative men.
