The authors examined HIV risk-related sexual behaviors in an ethnically diverse sample of HIV seropositive gay and bisexual men (N?=?86). Measures of sexual behavior, substance use, condom attitudes, behavior change intentions, and engagement in risk-reducing practices were completed. Thirty-nine percent of the men reported engaging in unprotected anal intercourse in the past 3 months. Unprotected anal intercourse was associated with using nitrite inhalants, sex partners who used substances before sex, and low intentions to change risk behavior. These results highlight the difficulties that people living with HIV infection face in maintaining a lifetime of safer sex and the necessity of integrating clinical and prevention interventions for these persons.

Positive purpose in life (PIL) has been shown to influence health maintenance, facilitate recovery from illness, and enhance psychological well-being. Among persons diagnosed with human immunodeficiency virus (HIV) disease, PIL has received minimal attention. This study used a convenience sample of 67 men who had a diagnosis of acquired immunodeficiency syndrome (AIDS) or who participated in high-risk sexual behavior associated with HIV disease to measure PIL. Integrating qualitative data into the final analysis contributed to a greater understanding of PIL among persons with HIV disease and those at high risk for the disease. Results of the study demonstrated a significantly lower PIL score for men with AIDS. PIL scores were negatively correlated with religious beliefs for the group, and these scores were not influenced by the interval since the AIDS diagnosis. Men with HIV disease are often isolated and withdrawn from society and appear to lack clear meaning for existence.  相似文献

Gay Community Attachment has proved a significant predictor of successful behavior change among gay-identifying men in response to HIV/AIDS. Related work at Macquarie University, Sydney, Australia, indicated that attachment to gay community is not a simple issue; rather, complex issues of sexual identity formation, the constraints of social inequality and localized sexual cultures inhibit the process of attachment and, therefore, successful HIV prevention. This paper discusses some of the findings from close-focus (qualitative) research on older homosexually active men which explore in depth the dynamic whereby these men attached themselves to gay community in terms of an analysis of class, generation, and the interplay with self-construction and masculinity.  相似文献

INTRODUCTION: This longitudinal study examined the prevalence and demographic correlates of unprotected insertive and receptive anal intercourse among HIV-positive gay and bisexual men who were aware of their serostatus. METHODS: Participants (n = 395), sampled randomly at two HIV outpatient clinics in Los Angeles, completed two waves of self-administered questionnaires (separated by approximately 7-9 months) that measured sexual behaviors in the previous 60 days. RESULTS: The cross-sectional prevalence of unprotected insertive anal intercourse was 11.2% at time 1 and 7.1% at time 2. Longitudinal analysis indicated that nearly 15% of the participants had engaged in that high-risk behavior either at time 1 or time 2 and approximately 4% had engaged in the behavior at each time period. Similar rates of unprotected receptive anal intercourse were observed. These high-risk activities were more prevalent with seropositive and unknown serostatus partners than with seronegative partners. The rate of anal intercourse risk behaviors was higher among asymptomatic men and among those who were exclusively gay. CONCLUSION: The findings demonstrate considerable differences in the prevalence of stable and occasional high-risk sexual behaviors among HIV-positive gay and bisexual men. Simple cross-sectional analyses cannot capture the stability or variation in behavior across time and, thus, may generate misleading conclusions about disease transmission, especially if the partner's HIV serostatus is not considered in the analysis. The findings indicate a need for focused safer-sex interventions for seropositive men. The HIV outpatient clinic is an ideal setting for such interventions.  相似文献

The present study followed a group of 100 gay men up to 1 year before and 1 year after losing a partner to AIDS (University of California, San Francisco Coping Project). Following bereavement, participants were at increased risk for engaging in unprotected anal intercourse: at 4 to 6 months for HIV-negative men and at 8 to 12 months for HIV-positive men. Sociodemographic variables, HIV serostatus, substance use, depression, prebereavement relationship quality, and social support did not explain sexual risk-taking in this sample. However; men who engaged in unprotected anal intercourse were twice as likely to be involved in a new primary relationship as those who did not. The authors concluded that risk varies over time by HIV status and may involve engagement in new relationships. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The authors evaluated sexual practices, sexually tempting situations, and risk avoidance coping strategies among HIV-seropositive men who have sex with men and who were seeking HIV prevention services. HIV-seropositive men who practiced unprotected anal intercourse in the previous 4 weeks reported stronger temptations to engage in high-risk sex than men who were sexually safe. Being in a positive mood and being with desirable partners were particularly tempting risk situations for seropositive men, who also possessed less coping capacity to deal with risky situations than safer men. Prevention interventions must address the needs of men infected with HIV and must remove barriers to enrolling in prevention programs.

Research linking sensitivity to others and their evaluation of the self to alterations in physiologic function led the authors to examine whether HIV infection might progress more rapidly in gay men who are particularly sensitive to social rejection. Analyses of data from a 9-year prospective study of 72 initially healthy HIV-positive gay men indicated that rejection-sensitive individuals experienced a significant acceleration in times to a critically low CD4 T lymphocyte level, times to AIDS diagnosis, and times to HIV-related mortality (despite control for a variety of potential biobehavioral confounders). Accelerated HIV progression was not observed in rejection-sensitive gay men who concealed their homosexual identity, suggesting that concealment may protect such individuals from negative health effects. Data distinguishing rejection sensitivity from other health-relevant psychosocial characteristics are presented, and possible links to HIV pathophysiology are described.

Objective: This study examined how disengagement coping with HIV risk mediated the association between internalized homophobia and unprotected anal intercourse (UAI) and how sexual encounters in public venues (public sex) and drug use moderated the association between disengagement coping and UAI among HIV-negative gay men. Disengagement coping included fatalistic beliefs about maintaining HIV-negative seronegative serostatus (fatalism), optimistic attitudes toward medical seriousness of HIV infection and reduced concern about HIV risk due to highly active anti-retroviral therapies (optimism), and negative affective states associated with sexual risk (anxiety). Design: A survey was conducted among 285 HIV-negative gay men at an HIV prevention counseling program in New York City. Main Outcome Measures: Sexual risk was defined as having had UAI with nonprimary partners in the past 6 months. Results: In addition to the positive association between internalized homophobia, disengagement coping, and UAI, fatalism mediated the association between internalized homophobia and UAI; and optimism mediated the association between anxiety and UAI. A significant moderation effect of public sex was found between fatalism and UAI. Conclusions: The findings highlight the importance of understanding disengagement coping as it affects sexual risk practices among HIV-negative gay men in the continuing epidemic.

The relationship was examined between self-esteem, social support, internalized homophobia, and coping strategies used by gay men (N?=?89) who were positive for human immunodeficiency virus (HIV) and between the use of coping strategies and mood state. Multiple regressions were conducted with avoidant (escape avoidance, accepting responsibility) and proactive (seeking social support, planful problem solving) coping serving as criterion variables. Greater homophobia and less self-esteem predicted avoidant coping, whereas less homophobia and less time since diagnosis predicted proactive coping. Greater time since diagnosis, less avoidant coping, less homophobia, and greater self-esteem predicted better mood state and accounted for 50% of the total variance.

Safer-sex guidelines established during the early days of the HIV/AIDS epidemic have undergone very little revision despite some controversy. Although these guidelines have been widely disseminated in the gay community, many gay men continue to engage in behaviors that are believed to put them at high risk for transmission of HIV. This suggests either that they have not accepted safer-sex guidelines as accurate or that other factors override personal implementation of the guidelines. The study examined seronegative gay men's beliefs about the accuracy of safer sex guidelines and the men's participation in behaviors risky for transmitting HIV. The greatest disagreement between the men's beliefs and behaviors centered on the risk of oral intercourse; this suggests a need for clarification of the safer sex message about this behavior. The findings of this study support the need to reformulate safer-sex guidelines. When unprotected oral and anal sex are classified at the same level of risk, those who engage in unprotected oral sex may proceed to unprotected anal sex with less reservation.  相似文献

The actions of substance P and thyrotropin-releasing hormone (TRH) on neonatal rat spinal motoneurones in vitro were compared using intracellular current and voltage clamp techniques. Like TRH, substance P evoked a slowly-developing, persistent depolarisation plus an increase in input resistance under current clamp conditions. Under voltage clamp conditions, substance P elicited an inward current (mainly due to a conductance block) which peaked near -40 mV and reversed polarity close to the estimated EK. A distinct conductance increase (with a reversal potential near zero) also appeared to contribute to this response. The response to substance P at resting potential was suppressed by 1.5 mM Ba2+, but not by 20 mM tetraethylammonium, 2 mM 4-aminopyridine, 2 mM Cs+ and 0.2 mM Cd2+. In addition, co-application of TRH and substance P mutually occluded each other. Thus, it is suggested that substance P and TRH share a common effector mechanism, which primarily involves the suppression of IK(T), a persistent K+ current recently discovered in these neurones.  相似文献

This study surveyed 430 men at an urban gay pride celebration to assess fatalism, current life satisfaction, and perceived expected years of life among men who have sex with men. Analyses showed that men who engaged in unprotected anal intercourse outside of exclusive relationships reported a greater fatalistic outlook, were more dissatisfied with life, and perceived a shorter life for themselves than men who practiced only safer sex and men who were in exclusive relationships. Gay men in exclusive relationships scored higher than nonexclusively partnered gay men on the measure of current life satisfaction. These results suggest that efforts to prevent HIV infection among gay men should include building personal self-worth, support of long-term relationships, and future goal orientations.

The relationships among bereavement, depressed mood, and immunologic patterns prognostic for the development of AIDS were determined in a sample of HIV seropositive gay men and a comparison group of HIV seronegative gay men. Immunologic parameters were assessed in 45 men who had recently experienced the deaths of close friends and 45 matched nonbereaved men. No immune differences were found between bereaved and nonbereaved men. Among the HIV seropositive nonbereaved men, higher depressed mood was significantly associated with fewer CD4 (helper/inducer) T lymphocytes, more activated CD8 (suppressor/cytotoxic) T cells, and lower proliferative responses to the mitogen phytohemagglutinin. In summary, HIV seropositive men who reported higher levels of depressed mood not associated with bereavement demonstrated immunologic patterns consistent with HIV activity and progression.

Prebereavement predictors of the course of postbereavement depressive mood were examined in 110 gay men who were their partner's caregiver until the partner's death of AIDS. In all, 37 HIV+ and 73 HIV– bereaved caregiving partners were assessed bimonthly throughout a 10-month period beginning 3 months before and ending 7 months after the partner's death. Throughout the 10 months, mean Centers for Epidemiology Scale-Depression (CES-D) scores on depressive mood were above the cutoff for being at risk for major depression. CES-D scores decreased for 63% of bereaved caregivers over the 7 postbereavement months, and 37% showed little change from high CES-D scores or increasing CES-D scores. High prebereavement CES-D scores and finding positive meaning in caregiving predicted diminishing depressive mood; HIV+ serostatus, longer relationships, hassles, and use of distancing and self-blame to cope predicted unrelieved depressive mood.

The HIV epidemic in the United States has affected at least two generations of gay men. Despite numerous efforts to intervene on this public health crisis, HIV infections continue to escalate, especially among young men. This condition is compounded by an ever-growing number of gay men who are aging and living with HIV. We must enact an innovative and proactive vision and framework for HIV prevention that moves us beyond the undertakings rooted in social–cognitive paradigms that have informed this work for the past 25 years. A new framework for HIV prevention must give voice to gay men; must consider the totality of their lives; must delineate the underlying logic, which directs their relation to sex and HIV; and must concurrently respect their diverse life experiences. This approach should be rooted in a biopsychosocial paradigm, should be informed by both theory and practice, and should be directed by three theoretical lenses—a theory of syndemics, developmental theories, and contextual understandings of HIV disease. Taken together, these elements are a call to action for research and practice psychologists who are working to improve the lives of gay men.

A random conical tilt reconstruction of negatively stained Saccharomyces cerevisiae fatty acid synthase was used as a model to compute a three-dimensional reconstruction from untilted stain specimens of the molecules in multiple orientations using a three-dimensional projection alignment method. The resulting structure (24 A resolution) has a more uniform resolution than the initial structure and the handedness revealed in the random conical tilt method is preserved. In a similar approach, this model was used to compute a 21-A-resolution frozen-hydrated structure from untilted specimens of the molecules in multiple orientations. Even though the reconstructions are in close agreement, the stain structure appears to enhance the protein density associated with less robust features. These procedures significantly reduce the time and effort required to obtain a three-dimensional reconstruction from frozen-hydrated data with a resolution that is comparable to the best obtained by more laborious methods. The agreement between the stain and frozen-hydrated reconstructions affords convincing evidence concerning the validity of the structure and the information afforded by the two reconstructions significantly enhances the structural analysis of the molecule.  相似文献

Risk behavior for HIV transmission among gay men surveyed in Seattle bars   总被引:1,自引:0,他引:1  
Men attending four Seattle gay bars were asked to complete a self-administered questionnaire including measures of sexual behavior, perceptions of peer norms in the area of sexual safety, personal human immunodeficiency virus (HIV) risk estimate, and knowledge and use of a variety of acquired immunodeficiency syndrome (AIDS) prevention services. Twenty-nine percent of the sample reported engaging in unprotected anal intercourse at least once during the 2 months before the survey. Differences in peer norm perceptions, age, HIV risk estimate, and intent to be sexually safe in the future were found between those engaging in unprotected anal intercourse and those not reporting unprotected anal intercourse. No significant differences were found in level of education, use of AIDS prevention services, and whether or not a person had been tested for HIV. Implications for prevention programs are discussed.  相似文献

The pleasure or reinforcement value of high-risk sex may be an important influence on success in risk reduction efforts. Seronegative gay and bisexual men (N?=?297) completed measures assessing their unprotected and safer sex practices, as well as measures of cognitive and skill factors and a measure assessing the subjective reinforcement value of unprotected anal intercourse. Regression analyses showed that the reinforcement value of unprotected anal intercourse accounted for variance in predicting levels of condom use above that that could be accounted for by factors such as knowledge, behavior change intentions, perceived vulnerability, condom attitudes, and sexual communication skills. Only reinforcement value of unprotected sex and substance use significantly predicted how frequently participants engaged in high-risk sex. Increased attention to the valence of sexual reinforcers will improve HIV risk reduction models and enhance AIDS prevention efforts.

The aim of this study was to describe the sexual behaviour of men who had sex with both men and women in the preceding five years (behaviourally bisexual men), specifically to examine their needs in relation to HIV prevention. Anonymous telephone interviews were carried out with respondents recruited though advertisements in UK newspapers and magazines with (sexual) 'personal' or 'contact' sections. Data are reported from 745 respondents. Respondents report relatively high and approximately equal numbers of male and female sexual partners in the year preceding interview. There is a clear patterning of sexual activity by type of partner (regular or casual). A high proportion report anal intercourse with female and male partners. A third disclose their homosexual practices to regular female partners. Although self-reported HIV seroprevalence is low (less than 1%), the levels of unprotected sex with multiple sexual partners indicate substantial potential for transmission of sexually transmitted infections, including HIV. While low seroprevalence suggests that there is little overlap with existing core groups of HIV infection, the study provides information to judge the priority of targeting HIV prevention initiatives and suggests ways in which initiatives could be undertaken.  相似文献
