Condom use in unmarried Latino men: A test of cultural constructs.

The effects of cultural factors on condom use were assessed in a random digit-dialing household survey of 1,600 unmarried Latino adults in 10 states with large Latino populations. Measures of traditional gender-role beliefs, sexual coercion, sexual comfort, and self-efficacy in using condoms were developed specifically for this population. A multisample structural equation model analysis included 594 men who reported one or more heterosexual partners in the 12 months before interview. As predicted, men with more traditional gender-role beliefs reported more sexual coercion and less sexual comfort. Men reporting more sexual coercion and less sexual comfort had lower condom self-efficacy. Men with more condom self-efficacy and stronger condom social norms reported more condom use.

Condom use: A self-efficacy model.

A survey of heterosexually active college students gathered information about condom use, self-efficacy (SE), outcome expectancies, sexual attitudes, peer group influences, AIDS knowledge, and a perceived vulnerability to AIDS. On the basis of A. Bandura's (1986) social-cognitive theory, a structural model with SE as the central mediator was formulated and evaluated with LISREL. This model explained 46% of the variance in condom use from judgments of SE and effects attributable to peers and 53% of the variance in SE from outcome expectancies and peer group influences. Sexual attitudes, AIDS knowledge, and perceived vulnerability did not predict condom use. Most students were well-informed about HIV transmission but reported not feeling at risk, even though many engaged in risky sexual behavior.

The UCLA Multidimensional Condom Attitudes Scale: Documenting the complex determinants of condom use in college students.

Describes the development and validation of the UCLA Multidimensional Condom Attitudes Scale (MCAS). The relationships between the MCAS and gender, sexual experience, intentions to use a condom, and past condom use were assessed. The MCAS has 5 distinct factors: (1) Reliability and Effectiveness of condoms, (2) the sexual Pleasure associated with condom use, (3) the stigma attached to persons who use condoms (Identity Stigma), (4) the Embarrassment About Negotiation and Use of condoms, and (5) the Embarrassment About the Purchase of condoms. Results strongly suggest that condom attitudes are multidimensional and thus cannot meaningfully be summed to a single global score. Results further indicate that men and women hold very different attitudes toward condoms. Implications of scale multidimensionality and directions for future research are discussed.

Trajectories and determinants of alcohol use among LGB young adults and their heterosexual peers: Results from a prospective study.

Lesbians, gays, and bisexuals (LGBs) are at increased risk for alcohol use during young adulthood, but the mechanisms remain inadequately understood. The aim of the present study was to examine the trajectories and determinants of alcohol use among LGB young adults who were sampled prospectively. The sample included 111 LGB individuals (47 women and 64 men) and 2,109 heterosexuals (1,279 women and 830 men), who were assessed at three time points: during the summer after their senior year of high school and during the fall and spring of their freshman year of college. Hierarchical linear modeling analyses indicated that lesbians consumed more alcohol than their heterosexual peers during high school, whereas gay men increased their alcohol use at greater rates than heterosexual men during the initial transition to college. Positive alcohol expectancies and social norms mediated this relation for both men and women. The results extend the generalizability of these processes and highlight the importance of considering normative social-cognitive influences in the development of alcohol use among LGB young adults.

Condom use with a casual partner: What distinguishes college students' use when intoxicated?

Determining alcohol's precise role in sexual risk taking has proven to be an elusive goal. Past research has produced mixed results, depending on characteristics of individuals, their partners, and the situation, as well as how the link between alcohol consumption and sexual behavior was assessed. In this study, cross-sectional predictors of the frequency of condom use were examined for 298 heterosexual college students at a large urban university. In hierarchical multiple regression analyses that controlled for frequency of condom use when sober, alcohol expectancies regarding sexual risk taking and self-efficacy regarding condom use when intoxicated were significant predictors of frequency of condom use when intoxicated. These findings highlight the importance of targeting beliefs about alcohol's disinhibiting effects in STD- and HIV-prevention programs.

Bisexual and gay men in heterosexual marriage: conflicts and resolutions in therapy

This paper describes 31 men who at the time of entering therapy were married and expressed concern about their same-sex feelings and activity. Each of these man was treated in a "bisexuality group" designed to help him to be more comfortable and accepting of his same-sex feelings and to explore ways of incorporating same-sex and opposite-sex feelings into his life. Following treatment, 11 of the 31 men (36%) decided to end their marriage; twenty men (64%) decided to remain married. In a follow up study, there was a further attrition of marriages so that 14 remain married. The paper further describes attitudes and behavior prior to therapy, immediately following therapy, and at the time of follow up (up to three years). Factors that seem to be important ingredients of of successful adjustment are discussed.     

Psychosocial correlates of heterosexual condom use: a meta-analysis

Despite increasing incidence of HIV/AIDS, there has been no systematic review of correlates of condom use among heterosexual samples. To rectify this, the present study used meta-analysis to quantify the relationship between psychosocial variables and self-reported condom use. Six hundred sixty correlations distributed across 44 variables were derived from 121 empirical studies. Variables were organized in terms of the labeling, commitment, and enactment stages of the AIDS Risk Reduction Model (Catania, Kegeles, & Coates, 1990). Findings showed that demographic, personality, and labeling stage variables had small average correlations with condom use. Commitment and enactment stage variables fared better, with attitudes toward condoms, behavioral intentions, and communication about condoms being the most important predictors. Overall, findings support a social psychological model of condom use highlighting the importance of behavior-specific cognitions, social interaction, and preparatory behaviors rather than knowledge and beliefs about the threat of infection.     

Sexual relationships, risk behaviour, and condom use in the spread of sexually transmitted infections to heterosexual men

Adolescents attending 5 state schools for the deaf responded to a 35-item questionnaire designed to probe their knowledge of AIDS. The 129 students in grades 9-12 had extremely limited core knowledge of AIDS, with the correct answers to only 8 of the 35 questions known by most students in all 4 grades. A minority of males and females knew the answers to most questions, indicating that AIDS education programs for deaf adolescents are urgently needed.     

Neural correlates of sexual arousal in homosexual and heterosexual men.

Men exhibit much higher levels of genital and subjective arousal to sexual stimuli containing their preferred sex than they do to stimuli containing only the nonpreferred sex. This study used event-related functional magnetic resonance imaging to investigate how this category-specific pattern would be reflected in the brains of homosexual (n = 11) and heterosexual (n = 11) men. Comparisons of activation to preferred sexual stimuli, nonpreferred sexual stimuli, and sports stimuli revealed large networks correlated with sexual arousal, spanning multiple cortical and subcortical areas. Both homosexual and heterosexual men exhibited category-specific arousal in brain activity. Within the amygdala, greater preference-related activity was observed in homosexual men, but it is unclear whether this is a cause or a consequence of their sexuality. In a subsequent analysis of regions hypothesized to support arousal, both participant groups demonstrated widespread increases in evoked activity for preferred stimuli. Aggregate data from these regions produced significant differences between stimulus types in 16 out of 22 participants. Significant activational differences matched reported sexual orientation in 15 of these 16 participants, representing an advance in psychophysiological measures of arousal.

Birth order and sibling sex ratio in homosexual and heterosexual non-white men

Recent studies have detected basal ganglia atrophy in clinically asymptomatic persons with the genetic mutation that causes Huntington's disease (HD). Whether reductions in caudate and putamen volume on MRI scans are associated with changes in cognitive and neurologic functioning was examined in 13 healthy adults with the IT-15 mutation. Reduced striatal volume was found to correlate with greater neurologic (largely motor) impairment, slower mental processing speed, and poorer verbal learning, although none of the participants met even liberal criteria for clinical diagnosis of HD. These correlations are strikingly similar to those observed in symptomatic HD patients, possibly reflecting the earliest manifestations of disease.     

Gonorrhoea in the asymptomatic patient: presentation and the role of contact tracing for heterosexual men and women and for homosexual men

Clinically silent gonorrhoea is the major problem in the control of the disease. Only 12 per cent of infected women reported in 1974 because of symptoms, compared with 97 per cent of infected heterosexual men and only 35 per cent of homosexual men with gonococcal proctitis alone. Homosexual men, compared with heterosexual men, had twice as many subsequent sexual contacts after infection and had a higher incidence of early syphilis. Eighty-four per cent had experienced passive anorectal intercourse. Ninety-seven per cent of men with gonococcal urethritis reported because of symptoms, but occasionally (particularly after unsuccessful treatment) urethral gonorrhoea in men may be clinically silent and even require tests of the overnight urethral secretion for diagnosis. For women, and for homosexual men who have had passive anorectal (or oral) intercourse, the indication for attendance for tests for gonorrhoea should be having run the risk, and not the presence of symptoms. Routine tests of the anorectum for gonorrhoea are essential in cases of 80 women at risk, and for most homosexual men since over 80 per cent of these men will have had passive anorectal intercourse. Because gonococcal infections following treatment-failure are often clinically silent in both women and men, symptoms cannot be relied upon to indicate such failure. Follow-up smears and cultures are always essential.     

Close contacts with the endoplasmic reticulum as determinants of mitochondrial Ca2+ responses

The spatial relation between mitochondria and endoplasmic reticulum (ER) in living HeLa cells was analyzed at high resolution in three dimensions with two differently colored, specifically targeted green fluorescent proteins. Numerous close contacts were observed between these organelles, and mitochondria in situ formed a largely interconnected, dynamic network. A Ca2+-sensitive photoprotein targeted to the outer face of the inner mitochondrial membrane showed that, upon opening of the inositol 1,4,5-triphosphate (IP3)-gated channels of the ER, the mitochondrial surface was exposed to a higher concentration of Ca2+ than was the bulk cytosol. These results emphasize the importance of cell architecture and the distribution of organelles in regulation of Ca2+ signaling.     

Sex hustling, injection drug use, and non-gay identification by men who have sex with men. Associations with high-risk sexual behaviors and condom use

OBJECTIVE: To explore differences in demographic characteristies, risk practices, and preventive behaviors among subgroups of men who have sex with men (MSM), including gay- and non-gay-identified MSM, MSM who inject drugs, and those engaging in sex hustling. DESIGN: A secondary analysis of cross-sectional data collected through interviewer-administered questionnaires in a purposive sample of MSM. SETTING: Gay bars, bath houses, adult video arcades, and out-door crusing areas in Denver and Long Beach. PARTICIPANTS: Men who reported oral or anal sex with another man in the past year with oversampling of non-gay-identified MSM. RESULTS: Of 1,290 MSM, 417 (32%) did not gay-identify, 86 (7%) were drug injectors, and 117 (9%) were hustlers. Of drug-injecting MSM, 55% reported sex hustling and 40% of hustlers reported injection drug use. Hustling was associated with higher number of partners, more frequent anal sex with men and women, and less frequent condom use during anal sex with occasional male partners. Hustlers and drug-injecting MSM used condoms less consistently during vaginal intercourse with female partners than did other MSM. CONCLUSIONS: Among MSM, subgroups at particularly high risk for HIV can be identified. Although these subgroups may be relatively small, they may be important epidemiologic links to the larger MSM and heterosexual communities and warrant focused behavioral interventions to prevent the further spread of HIV.     

Regional distribution and incidence of human papillomavirus infections among heterosexual men and women with multiple sexual partners: a prospective study

OBJECTIVE: To assess prevalence, incidence and potential risk factors of human papillomavirus (HPV) infection among heterosexual men and women with multiple partners and to identify niches of HPV-infection. DESIGN: A prospective study of heterosexual men and women with multiple partners attending an STD clinic as participants in a study on HIV from May 1988 until January 1991. Routine STD examination and physical examination using colposcopy were performed, interviews with standardised questionnaires were administered. Specimens for HPV DNA detection by polymerase chain reaction were collected from multiple sites of the genital, anorectal and oral regions. In women cervical cytology was performed. SETTING: The STD Clinic of the Municipal Health Service of Amsterdam. PARTICIPANTS: 162 women and 85 men entered the study, 110 women and 48 men were followed up. RESULTS: At entry of the study 37 (23%) women and 24 (28%) men were found positive for HPV DNA at any site. Only in one woman was oral presence of HPV DNA found during follow-up. Abnormal cervical cytology was observed in four women. In multivariate analysis, diagnosis of condylomata [odds ratio (OR) 5.61, 95% confidence interval (CI) 1.86 to 16.90)], reporting genital dermatological abnormalities (OR 3.72, 95% CI 1.38 to 9.99) and age (OR per year 0.93, 95% CI 0.88 to 0.99) predicted independently the presence of HPV DNA in women at entry of the study. In women 59 of the 99 (60%) HPV infections were observed in the genital region and 40% in the anorectal region: in men these figures were 65% and 35%, respectively. The incidence of HPV infection was 47.1 and 50.5 per 100 person-years for women and men respectively. At least 20/99 (20%) infections in women were intermediate or long persistent and only 3/48 (6%) HPV infections in men (P = 0.03). No risk factor for persistency could be determined, either in women or in men. CONCLUSIONS: HPV infection was found to be a multicentric genital and/or anorectal event both in women and men. The oral presence of HPV DNA was detected only once in one of the participants. In women persistent HPV infection was more common than in men. Independent predictors for presence of HPV DNA in women were diagnosis of condylomata acuminata, reporting genital dermatologic abnormalities and age. Incidence of HPV infection in women turned out to be 47.1 infections per 100 person-years and for men 50.5 per 100 person-years.     

Condom use among young women: Modeling the theory of gender and power.

Objective: This study sought to articulate pathways between constructs from the theory of gender and power and their associations with sexual behavior. Design: The data were collected preintervention during a randomized controlled HIV prevention trial. Participants were 701 sexually active, unmarried African American females, aged 14–20, who were not pregnant, and were recruited from three health clinics in a southeastern US city. Structural equation modeling was used for the analyses. Main Outcome Measure: Self-reported condom use. Results: Theoretical associations yielded a well-fitting structural model across initial and cross-validation samples. A significant amount of variance was explained for the variables of condom use (R2 = .31, .18), partner communication (R2 = .30, .26), substance use during sex (R2 = .32, .51), and negative personal affect (R2 = .36, .48). Partner communication (.35, .38) was the strongest predictor of condom use, negative personal affect (?.41, ?.37) was the strongest predictor of partner communication, and physical risk (.54, .54) was the strongest predictor of negative personal affect. Conclusion: This model provides evidence to support both direct and indirect associations between social and behavioral risk factors and condom use. Associations between theory of gender and power constructs and condom use can facilitate future development and analyses of interventions based on this theory.

Empirical tests of an information-motivation-behavioral skills model of AIDS-preventive behavior with gay men and heterosexual university students.

This article contains empirical tests of the information-motivation-behavioral skills (IMB) model of AIDS preventive behavior (J. D. Fisher and W. A. Fisher; see PA, Vol 79:28622; W. A. Fisher and J. D. Fisher, 1993), which has been designed to understand and predict the practice of AIDS-preventive acts. The IMB model holds that AIDS-preventive behavior is a function of individuals' information about AIDS prevention, motivation to engage in AIDS prevention, and behavioral skills for performing the specific acts involved in prevention. The model further assumes that AIDS-prevention information and motivation generally work through AIDS-prevention behavioral skills to influence the initiation and maintenance of AIDS-preventive behavior. Supportive tests of the model, using structural equation modeling techniques, are reported with populations of gay male affinity group members (n?=?91) and heterosexual university students (n?=?174).
