Focusing "down low": bisexual black men, HIV risk and heterosexual transmission.

INTRODUCTION: Black men who have sex with men (MSM) and women but who do not identify as gay or disclose their bisexual activities to main female partners, also known as men "on the down-low," have been cited as the main reason for the increase in HIV infections in black women. METHODS: Three online databases (PsychInfo, MEDLINE and AIDSLINE) were searched for scientific articles related to men on the down-low. A total of 24 articles and two conference abstracts were selected for review. RESULTS: Data from existing studies of MSM reveal low agreement between professed sexual identity and corresponding sexual behavior among black and other MSM; show that black MSM are more likely than MSM of other racial or ethnic groups to be bisexually active or identified; and, compared with white MSM, are less likely to disclose their bisexual or homosexual activities to others. However, black MSM who do not disclose their homosexual or bisexual activities engage in a lower prevalence of HIV risks than black MSM who do disclose; and black men who are currently bisexually active account for a very small proportion of the overall population of black men (2%). CONCLUSION: The high prevalence of HIV in the black community and the greater likelihood of bisexuality among black men place heterosexual black women at risk for HIV infection. However, the contribution of high-risk heterosexual black men to the rising HIV caseload among black women has been largely ignored. Future research must evaluate the relative contributions of bisexual men and exclusively heterosexual black men to HIV cases among black women.

Lesbian and bisexual women in small cities--at risk for HIV? HIV Prevention Community Collaborative.

Objectives.Women who have sex with women are a relatively hidden group that has been overlooked in most AIDS research and prevention efforts, primarily because the efficiency of HIV transmission between female partners is believed to be low. Although data are scant, it is commonly assumed that members of this population are not at high risk for HIV infection. However, a recent study of lesbian and bisexual women living in the San Francisco Bay area reported a relatively high seroprevalence rate and has raised additional questions about this group's HIV risk. The present study, the first to focus on lesbian and bisexual women living outside major AIDS epicenters, provides additional evidence. It describes risk factors for HIV transmission among lesbian and bisexual women living in small cities in four geographic regions of the United States.Methods.On three consecutive evenings in 1992, members of the research team distributed anonymous structured written surveys to women patrons as they entered gay bars in each of 16 small cities.Results.Almost 17% of bisexual respondents and 0.5% of lesbians reported having had unprotected vaginal or anal sex with a male during the two months prior to the survey. Almost 10 percent of bisexual women and 8.8% of lesbians in the sample reported a history of injection drug use. Among those women surveyed who said they had been tested, 1.4% reported they were infected with HIV.Conclusions.Self-identified sexual orientation was highly consistent with recent sexual behavior. HIV risk related to sexual behavior was concentrated among self-identified bisexual women. The prevalence of injection drug use was substantial among both bisexual and lesbians. Developers of HIV risk behavior programs should take the prevalence of these risk behaviors into consideration in the design of effective HIV prevention interventions tailored to the needs of this hidden population.

Differences in HIV risk characteristics between bisexual and exclusively gay men.

Research investigating HIV-risk sexual behaviors of men who have sex with men usually combines gay and bisexual men, treating them as a single, homogeneous group. However, gay and bisexual men may differ in their HIV risk behavior and in psychological characteristics indicative of risk. Exclusively gay (N = 1,180) and bisexual men (N = 136) completed anonymous surveys at gay bars. The surveys assessed demographic, psychological, and behavioral data related to sexual behavior and HIV risk. Relative to exclusively gay men, bisexual men had lower intentions to use condoms in their next intercourse occasion, reported a greater frequency of oral sex with men and more oral-sex partners, knew fewer people who were HIV positive, and perceived weaker peer norms favoring safer sex and risk avoidance. One-third of bisexual men reported engaging in unprotected anal intercourse, and 17% of bisexual men had multiple unprotected anal sex partners in the past two months. Interventions tailored to the needs of bisexual men are urgently needed and should focus on increasing intentions to use condoms, increasing HIV-risk sensitization, and fostering norms favoring safer sex and risk avoidance.

Smoking among lesbians, gays, and bisexuals: a review of the literature.

OBJECTIVES: To collect estimates of smoking prevalence among lesbian, gay, and bisexual people from the published literature and to compare with general population estimates. METHODS: Databases were searched for all studies published in English on tobacco use among lesbians, gays, and bisexuals. From 1987 through 2000, twelve studies were identified (four youth, eight adult): seven were based on convenience samples; one on a population-based probability sample; one involved random sampling within selected census tracts; one was based on a large multicenter clinical trial; and two were representative school-based samples. Study findings were compared to national survey data from the corresponding time period. RESULTS: Estimated smoking rates for lesbians, gays, and bisexuals ranged from 38% to 59% among youth and from 11% to 50% among adults. National smoking rates during comparable periods ranged from 28% to 35% for adolescents and were approximately 28% for adults. CONCLUSIONS: While information in the published literature is limited, it appears that smoking rates are higher among adolescent and adult lesbians, gays, and bisexuals than in the general population. Steps should be taken to ensure representation of lesbians, gays, and bisexuals in tobacco-use surveillance and to collect data in order to understand the apparent high smoking rates in these groups. Attempts should be made to target prevention and cessation interventions to lesbians, gays, and bisexuals.

Substance use and misuse: are bisexual women at greater risk?

The objective of this study was to compare the prevalence of substance use and alcohol-related consequences among bisexual and heterosexual women. A cross-sectional survey was self-administered to a random sample of undergraduate women. The final sample consisted of 49 self-identified bisexual women and 2,042 self-identified heterosexual women. Bivariate and multivariate results indicated that bisexual women were more likely than heterosexual women to report cigarette smoking, illicit drug use and medically prescribed use of antidepressant prescription medication. Although their drinking behaviors were similar, bisexual women were more likely than heterosexual women to experience adverse alcohol-related consequences. These findings suggest that traditional-age undergraduate women who self-identify as bisexual may be at heightened risk for substance use. However, additional research is needed to replicate these findings with larger samples of bisexual women.

Very young gay and bisexual men are at risk for HIV infection: the San Francisco Bay Area Young Men's Survey II.

OBJECTIVES: To compare HIV seroprevalence and sexual risk behavior among very young gay and bisexual men (aged 15-17 years) and their older counterparts (aged 18-22 years). To examine drug-use patterns and correlates of sexual risk behavior in both of these age groups. DESIGN AND METHODS: An interviewer-administered cross-sectional survey of 719 gay and bisexual males between 15 and 22 years old was conducted through a venue-based sampling design. Blood specimens were collected and tested for HIV antibodies, hepatitis B, and syphilis. Interviews assessed sexual and drug-use behavior as well as psychosocial variables believed to be related to sexual risk-taking, including self-acceptance of gay or bisexual identity, perceptions of peer norms concerning safer sex, and perceptions of the ability to practice safer sex (safer sex self-efficacy). RESULTS: Of the 719 participants, 100 (16.2%) were aged between 15 and 17 years. HIV seroprevalence was somewhat lower among those aged 15 to 17 years (2.0%) compared with those aged 18 to 22 years (6.8%). Overall, the prevalence of hepatitis-B core antibody was significantly lower in the younger age group (5.0%) than in the older group (14.1%). The men aged 15 to 17 years used alcohol, ecstasy, and heroin less frequently than those aged 18 to 22 years. The age groups did not differ in the proportion of men who reported any unprotected anal intercourse in the previous 6 months (31.2%). In both age groups, use of amphetamines, ecstasy, and amyl nitrate was associated with unprotected anal intercourse. Self-acceptance of gay or bisexual identity was related to less sexual risk for those aged 15 to 17 years. In both age groups, greater safer sex self-efficacy was linked to less HIV sexual risk-taking. In the younger group, perceptions of peer norms that support safer sex were related to less risk behavior. CONCLUSIONS: Very young gay and bisexual men engage in unprotected anal sex at rates comparable with those for their somewhat older counterparts, raising serious concern over their risk of acquiring HIV infection. To prevent seroconversions, interventions must target those <18 years of age, and prevention programs should address the use of certain drugs in relation to sex and sexual risk-taking. To be most effective, programs should develop innovative communication strategies to take into account lack of self-acceptance of gay or bisexual identity and low self-efficacy for practicing safer sex.

Sexual risk, substance use, and psychological distress in HIV-positive gay and bisexual men who also inject drugs.

OBJECTIVES: Gay and bisexual men and injection drug users (IDU) are the two main groups at risk of HIV exposure in the United States, but few studies have focused on the intersection of these two groups. Little is known about HIV-positive gay and bisexual IDU. The aim of this study is to identify and compare differences in HIV transmission risk behaviors and psychological distress in HIV-positive gay and bisexual men by injection versus non-injection drug use. METHODS: Data were from the baseline assessment of a randomized controlled trial of an HIV prevention intervention for HIV-positive gay and bisexual men. RESULTS: Of the 1168 men, 236 (20%) reported injection drug use, 500 (43%) reported only non-injection drug use, and 422 (36%) reported no drug use. More of the IDU reported having sex with women, and identified themselves as "barebackers" (i.e. men who intentionally have unprotected anal intercourse). IDU reported more unprotected sexual behaviors than men who did not use drugs, but their sexual risk behaviors were similar to those of men who used non-injection drugs. IDU, compared with other drug users, reported more use of non-injected methamphetamine, amphetamine, barbiturates, and gamma hydroxybutyrate. More IDU, compared with the other two groups, reported sexual abuse, anxiety, and hostility. CONCLUSION: HIV-positive gay and bisexual IDU are a distinct group from other HIV-positive gay and bisexual men. Prevention case management and interventions that help men cope with multiple health concerns and prevent HIV transmission are needed for this population.

Sexual arousal patterns of bisexual men.

There has long been controversy about whether bisexual men are substantially sexually aroused by both sexes. We investigated genital and self-reported sexual arousal to male and female sexual stimuli in 30 heterosexual, 33 bisexual, and 38 homosexual men. In general, bisexual men did not have strong genital arousal to both male and female sexual stimuli. Rather, most bisexual men appeared homosexual with respect to genital arousal, although some appeared heterosexual. In contrast, their subjective sexual arousal did conform to a bisexual pattern. Male bisexuality appears primarily to represent a style of interpreting or reporting sexual arousal rather than a distinct pattern of genital sexual arousal.

Beyond gender: the basis of sexual attraction in bisexual men and women.

The construct of sexual orientation has typically considered the gender of the sexual partner as defining whether the individual is homosexual, bisexual, or heterosexual, and the Kinsey scale conceptualises bisexuality as a point midway between homosexuality and heterosexuality. We propose an alternative model which places homosexuality and heterosexuality at one end of a continuum as gender-linked choices of sexual partner, and bisexuality at the other as nongender-specific. As a test of this model, we administered repertory grids to nine bisexual men and women to investigate the characteristics of sexual attraction in individuals for whom gender of partner was not a critical variable. Results supported the hypothesis that gender is not a critical variable in sexual attraction in bisexual individuals. Personality or physical dimensions not related to gender and interaction style were the salient characteristics on which preferred sexual partners were chosen, and there was minimal grid distance between preferred male and preferred female partners. These data support the argument that, for some bisexual individuals, sexual attraction is not gender-linked.

Primary care for lesbians and bisexual women.

For the most part, lesbians and bisexual women face the same health issues as heterosexual women, but they often have difficulty accessing appropriate care. Physicians can improve care for lesbians and bisexual women by acknowledging the potential barriers to care (e.g., hesitancy of physicians to inquire about sexual orientation and of patients to disclose their sexual behavior) and working to create a therapeutic physician-patient relationship. Taking an inclusive and nonjudgmental history and being aware of the range of health-related behaviors and medicolegal issues pertinent to these patients enables physicians to perform relevant screening tests and make appropriate referrals. Some recommendations, such as those for screening for cervical cancer and intimate partner violence, should not be altered for lesbians and bisexual women. Considerations unique to lesbians and bisexual women concern fertility and medico-legal issues to protect familial relationships during life changes and illness. The risks of suicidal ideation, self-harm, and depression may be higher in lesbians and bisexual women, especially those who are not open about their sexual orientation, are not in satisfying relationships, or lack social support. Because of increased rates of nulliparity, the risks of conditions such as breast and ovarian cancers also may be higher. The comparative rates of alcohol and drug use are controversial. Smoking and obesity rates are higher in lesbians and bisexual women, but there is no evidence of an increased risk of cardiovascular disease.

Male bisexual behavior and HIV risk in the United States: synthesis of research with implications for behavioral interventions.

This paper reviews recent literature on male bisexuality and HIV risk and suggests new directions for intervention and research in the United States. AIDS case reports and behavioral studies based on convenience samples suggest that behaviorally bisexual men use condoms inconsistently with male and female partners, seldom disclose their bisexuality to their female partners, and are more likely than exclusively homosexual men to report multiple HIV risk behaviors. Male bisexuality may present greatest HIV risk in the context of (a) male prostitution, (b) injecting drug use, (c) sexual identity exploration, and (d) culturally specific gender roles and norms such as those that may characterize some African American and Hispanic communities in the United States. We review individual and community level interventions to reach men within these four contexts as well as the larger population of bisexual men. We also suggest a heuristic model to encourage additional research examining multiple dimensions of bisexual behavior and HIV risk.

Bisexuality: some comments on research and theory.

Though evidence suggests that bisexuals may outnumber homosexuals and that bisexuality is increasing, there is a paucity of research on this group. Further, because researchers have included large numbers of bisexuals as "homosexuals" in their studies of homosexuality, we cannot even be sure of what we know about homosexuals. The author examines a variety of issues: sex differences, life-styles, discrimination, changes in sexual orientation over the life span, etc. Four beliefs about bisexuals are presented and examined: Bisexuality as: (1) real and natural, (2) transitory (the bisexual will become exclusive at the orientation opposite to his or her original orientation), and (4) homosexual denial.

Identity conflict or adaptive flexibility? Bisexuality reconsidered.

A definition of bisexuality is offered, followed by a discussion of two opposing models of bisexual functioning: the "conflict model," which views bisexuality as problematic, stemming from identity conflict and confusion that marks a transitional stage to a homosexual orientation; and the "flexibility model," which views bisexuality as the coexistence of heteroeroticism and homoeroticism, as the successful integration of homosexual and heterosexual identities into a dual sexual orientation. The Kinsey data are reviewed in an effort to determine the incidence of bisexuality in the U.S. population. Finally, specific clinical and empirical studies investigating bisexual subjects are reviewed in light of the two models.

Psycho-social issues related to counseling bisexuals.

An increasing number of persons who experience bisexual feelings or behaviors are seeking professional counseling. This article explores the psycho-social issues related to counseling individuals and couples concerned about their own or their partner's feelings, fantasies, or behaviors with both men and women, and the appropriateness or inappropriateness of adopting a bisexual identity or developing a bisexual life-style. The steps for helping individuals to differentiate problems, handle confusion, and conceptualize bisexuality are outlined. The counseling process with bisexuals includes developing support systems, examining internalized homophobia and sex-role stereotyping, helping them deal with heterosexual concerns, and with issues which affect partners when one or both is bisexual.

Spontaneous otoacoustic emissions in heterosexuals, homosexuals, and bisexuals.

Click-evoked otoacoustic emissions (CEOAEs) were previously shown to be significantly less strong in homosexual and bisexual females than in heterosexual females. Here it is reported that the spontaneous otoacoustic emissions (SOAEs) of those same 60 homosexual and bisexual females were less numerous and weaker than those in 57 heterosexual females. That is, the SOAEs of the homosexual and bisexual females were intermediate to those of heterosexual females and heterosexual males. The SOAE and CEOAE data both suggest that the cochleas of homosexual and bisexual females have been partially masculinized, possibly as part of some prenatal processes that also masculinized whatever brain structures are responsible for sexual orientation. For males of all sexual orientation, the SOAEs were less numerous and weaker than for the females, and there were no significant differences among the 56 heterosexual, 51 homosexual, and 11 bisexual males. All subjects passed a hearing screening test. When all SOAEs above 3000 Hz were excluded (as a control against incipient, undetected hearing loss) the same results were obtained as with the full range of data (550-9000 Hz). The differential use of oral contraceptives by the heterosexual and nonheterosexual females also could not explain the differences in their OAEs.

Treating the bisexual client.

Therapists, having recently come to terms with treating gay and lesbian clients, now must consider the issues that bisexual clients face. This article reviews the literature on what it means to identify as bisexual in a world where sexual identity is viewed as dichotomous, heterosexual at one end and gay or lesbian at the other end. The article explores sexual identity and its biological versus social origins, internalized biphobia, coming out, relationship patterns, and therapist issues. Two cases illustrate issues that might arise when a therapist is treating a bisexual client. The first case is a 17-year-old young woman who is accepting of her bisexual identity, and the second case is a 56-year-old woman, heterosexually identified and married, who suddenly fell in love with a woman. Concluding remarks focus on some future directions for research and work with bisexual clients.

Suicidal acts and ideation in homosexual and bisexual young people: a study of prevalence and risk factors.

BACKGROUND: Suicide attempts are the most robust clinical predictor of suicide, which is now the second cause of death among young people in many countries. Previous research has shown an increased risk of attempted suicide associated with a homosexual orientation. However, the mechanisms underlying this increased risk are not yet clear. This study therefore aimed to determine the risk of attempted suicide and the effect of potential risk factors on the occurrence of suicidal ideation and behaviour among homosexual youngsters. METHODS: The association between suicidal ideation and behaviour and potential risk factors was assessed by means of a questionnaire in a general population sample of homosexual or bisexual young people and a control sample consisting of school pupils. RESULTS: A twofold increased risk of suicidal ideation was found associated with a homosexual or bisexual orientation. A significantly increased risk of attempted suicide associated with homosexuality or bisexuality was found in females. Independent of sexual orientation, depression was identified as a significant risk factor for suicidal ideation, while suicidal behaviour was associated with low self-esteem, higher levels of hopelessness and suicidal behaviour in someone close. Among homosexual or bisexual young people, less satisfying homosexual friendships were an additional risk factor for suicidal behaviour. CONCLUSIONS: The identified increased risk of suicidal ideation among homosexual or bisexual young people is associated with depression and may lead to suicidal behaviour, independent of sexual orientation, especially in the presence of a role model of suicidal behaviour, and among those with unsatisfying friendships.

Comparison of auditory evoked potentials in heterosexual, homosexual, and bisexual males and females.

The auditory evoked potentials (AEPs) elicited by click stimuli were measured in heterosexual, homosexual, and bisexual males and females having normal hearing sensitivity. Estimates of latency and/or amplitude were extracted for nine peaks having latencies of about 2-240 ms, which are presumed to correspond to populations of neurons located from the auditory nerve through auditory cortex. For five of the 19 measures obtained, the mean latency or amplitude for the 57 homosexual and bisexual females was different from that of the 49 heterosexual females in a manner that implies a masculinization of the auditory systems of the homosexual and bisexual females. A similar masculinization effect was previously observed for the otoacoustic emissions generated by the cochlea. For five other measures, the mean latency or amplitude for the 53 homosexual and bisexual males was different from that of the 50 heterosexual males in a manner that implies a hypermasculinization of the auditory systems of the homosexual and bisexual males. Hypermasculinization has been reported recently for other physical characteristics of homosexual males. One parsimonious interpretation of these findings is that homosexual males and females both were exposed to higher than normal levels of androgens at some point(s) in development. Data are reported only for the female subjects not using oral contraceptives because those drugs can masculinize certain AEP measures.
