Prevalence of AIDS-related risk factors and condom use in the United States

Resilience and Its Limits: The Roles of Individual Resilience, Social Capital, Racial Discrimination, and Binge Drinking on Sexual Behavior Among Black Heterosexual Men

In response to the increased recognition of racism as a public health crisis, we assessed links between racial discrimination and HIV-related risk behavior for Black men. Specifically, using survey data from 530 Black heterosexual men (18-44 years old, M = 31.0, SD = 7.8), we tested two moderated-mediation models: (1) a protective model, in which resilience and social capital protected against the indirect effect of racial discrimination on alcohol-related sexual behavior via binge drinking, and (2) a bounded model, in which racial discrimination limited the indirect effects of resilience and social capital on alcohol-related sexual behavior via binge drinking. We found support for the bounded model only. Specifically, resilience was indirectly associated with decreased alcohol-related sexual behavior via lower binge drinking when racial discrimination was low to moderately high, but not when racial discrimination was at its highest levels. Resilience was not directly associated with alcohol-related sexual behavior. Social capital was directly related to lower odds of alcohol-related sexual behavior. At high levels of racial discrimination, however, social capital was indirectly related to increased alcohol-related sexual behavior via binge drinking. High levels of racial discrimination limit beneficial effects of resilience on alcohol-related sexual behavior. Social capital maintains a beneficial effect if social bonds are not associated with binge-drinking norms or behaviors. Results highlight the limitations of individual-level resilience and the need to conceptualize and support resilience as a social-structural resource.

Behavioural intervention to reduce sexually transmitted infections in people aged 16–24 years in the UK: the safetxt RCT

Background

The prevalence of genital chlamydia and gonorrhoea is higher in the 16–24 years age group than those in other age group. With users, we developed the theory-based safetxt intervention to reduce sexually transmitted infections.

Objectives

To establish the effect of the safetxt intervention on the incidence of chlamydia/gonorrhoea infection at 1  year.

Design

A parallel-group, individual-level, randomised superiority trial in which care providers and outcome assessors were blinded to allocation.

Setting

Recruitment was from 92 UK sexual health clinics.

Participants

Inclusion criteria were a positive chlamydia or gonorrhoea test result, diagnosis of non-specific urethritis or treatment started for chlamydia/gonorrhoea/non-specific urethritis in the last 2 weeks; owning a personal mobile phone; and being aged 16–24 years.

Allocation

Remote computer-based randomisation with an automated link to the messaging system delivering intervention or control group messages.

Intervention

The safetxt intervention was designed to reduce sexually transmitted infection by increasing partner notification, condom use and sexually transmitted infection testing before sex with new partners. It employed educational, enabling and incentivising content delivered by 42–79 text messages over 1 year, tailored according to type of infection, gender and sexuality.

Comparator

A monthly message regarding trial participation.

Main outcomes

The primary outcome was the incidence of chlamydia and gonorrhoea infection at 12 months, assessed using nucleic acid amplification tests. Secondary outcomes at 1 and 12 months included self-reported partner notification, condom use and sexually transmitted infection testing prior to sex with new partner(s).

Results

Between 1 April 2016 and 23 November 2018, we assessed 20,476 people for eligibility and consented and randomised 6248 participants, allocating 3123 to the safetxt intervention and 3125 to the control. Primary outcome data were available for 4675 (74.8%) participants. The incidence of chlamydia/gonorrhoea infection was 22.2% (693/3123) in the intervention group and 20.3% (633/3125) in the control group (odds ratio 1.13, 95% confidence interval 0.98 to 1.31). There was no evidence of heterogeneity in any of the prespecified subgroups. Partner notification was 85.6% in the intervention group and 84.0% in the control group (odds ratio 1.14, 95% confidence interval 0.99 to 1.33). At 12 months, condom use at last sex was 33.8% in the intervention group and 31.2% in the control group (odds ratio 1.14, 95% confidence interval 1.01 to 1.28) and condom use at first sex with most recent new partner was 54.4% in the intervention group and 48.7% in the control group (odds ratio 1.27, 95% confidence interval 1.11 to 1.45). Testing before sex with a new partner was 39.5% in the intervention group and 40.9% in the control group (odds ratio 0.95, 95% confidence interval 0.82 to 1.10). Having two or more partners since joining the trial was 56.9% in the intervention group and 54.8% in the control group (odds ratio 1.11, 95% confidence interval 1.00 to 1.24) and having sex with someone new since joining the trial was 69.7% in the intervention group and 67.4% in the control group (odds ratio 1.13, 95% confidence interval 1.00 to 1.28). There were no differences in safety outcomes. Additional sensitivity and per-protocol analyses showed similar results.

Limitations

Our understanding of the mechanism of action for the unanticipated effects is limited.

Conclusions

The safetxt intervention did not reduce chlamydia and gonorrhoea infections, with slightly more infections in the intervention group. The intervention increased condom use but also increased the number of partners and new partners. Randomised controlled trials are essential for evaluating health communication interventions, which can have unanticipated effects.

Future work

Randomised controlled trials evaluating novel interventions in this complex area are needed.

Social Support Networks among Delinquent Youth: An 8-Year Follow-up Study

Supportive social networks are key to the successful transition to young adulthood. Yet, we know little about networks of delinquent youth, a population at risk for disrupted social connections. This study describes the structure and function of social support networks among delinquent youth eight years after detention; median age 24 years. Nearly one-fifth of participants had no one that they could count on, and one-third had only one person in their support network. Participants tended to have very dense networks composed almost entirely of family. Findings underscore the importance of expanding social supports for delinquent youth as they age.

HIV Testing, Risk Behaviors, and Fear: A Comparison of Documented and Undocumented Latino Immigrants

Latino immigrants in the United States are at elevated risk for HIV infection and delayed HIV diagnosis. Immigration documentation status and its contribution to fears are important barriers to accessing health services including HIV testing. A currently changing political climate within the United States may have increased the complexity of the intersection of documentation status and health care access. This study used an anonymous survey conducted in March and April 2017 in New York City to compare: sociodemographic characteristics, HIV testing behaviors, HIV risk behaviors, and perceptions of fear around HIV testing among documented and undocumented Latino immigrants (N = 301). We found that undocumented immigrants reported lower levels of education, income, and health insurance than did documented immigrants. However, groups did not differ in having tested for HIV in the last 12 months, in future intentions to test for HIV, or in emotional/cognitive perceptions of fear around HIV testing. Undocumented immigrants reported lower rates of having ever tested for HIV in their lifetime (68.6%) than documented immigrants (80.5%) (p = 0.027). In conclusion, we found that despite sociodemographic challenges, undocumented immigrants had similar HIV testing behaviors as their documented counterparts in our study community. Further understanding of the mitigating factors that resulted in seemingly equal access to HIV testing in this community for undocumented immigrants is warranted.

A Smartphone Game-Based Intervention (Tumaini) to Prevent HIV Among Young Africans: Pilot Randomized Controlled Trial

Background

There is a pressing need to ensure that youth in high HIV prevalence settings are prepared for a safer sexual debut. Smartphone ownership is increasing dramatically in low-income and middle-income countries. Smartphone games that are appropriately grounded in behavioral theory and evidence-based practice have the potential to become valuable tools in youth HIV prevention efforts in Sub-Saharan Africa.

Objective

To pilot-test a theory-based, empirically grounded smartphone game for young Kenyans designed to increase age and condom use at first sex, aiming to establish directionality of effects on behavior change.

Methods

Tumaini (“hope for the future” in Swahili) is an interactive, narrative-based game grounded in social cognitive theory. A randomized controlled pilot study was conducted in Kisumu, Western Kenya, from April to June 2017 with 60 participants aged 11-14 (mean 12.7) years. Intervention arm participants (n=30) were provided with an Android smartphone with Tumaini installed on it and were instructed to play the game for at least 1 hour a day for 16 days; control arm participants (n=30) received no intervention. All participants completed a survey on behavioral mediators, delivered via an audio computer-assisted self-interview system at baseline (T1), post intervention (T2), and at 6 weeks postintervention (T3). The postintervention survey for intervention arm participants included questions eliciting feedback on the game. Intervention arm participants and their parents participated in 8 postintervention focus group discussions. Game log files were analyzed to calculate the length of exposure to the game. Behavioral survey data were analyzed using two-sample t tests to compare mean change from T1 to T2 and to T3 for intervention versus control arm participants. Descriptive statistics on game feedback questions were computed. Focus group transcripts were uploaded to MAXQDA software, where they were labeled with deductive and inductive codes. Data were analyzed thematically and compared across demographics.

Results

Intervention arm participants played Tumaini for a mean of approximately 27 hours. The intervention arm showed significant gains in sexual health-related knowledge and self-efficacy (both P<.001), behavioral intention for risk-avoidance strategies and sexual risk communication (P=.006), and overall survey scores (P<.001) compared with the control arm at T3. The postintervention survey revealed high subjective measures of the game’s value, relevance, and appeal. Focus groups identified a wide range of knowledge and skills the participants had gained, including setting goals and planning how to achieve them, which was perceived as a key motivator for avoiding or reducing risk.

Conclusions

The study supports the need for further research to assess the efficacy of the game-based intervention. If proven efficacious, smartphone games have the potential to dramatically increase the reach of culturally adapted behavioral interventions while ensuring fidelity to intervention design.

Factors Associated with Condom Use in the Male Population of Mexico City

Sexually transmitted diseases (STDs) are an important public health problem, due to their medical, social and economic repercussions. Therefore, more knowledge is needed about the sexual behaviour that promotes their spread, in order to improve control and prevention strategies.

Our aim was to determine the frequency of male condom use associated with sexual behaviour factors, a history of and knowledge about STDs in a sample of the male population in Mexico City. During 1994 a cross-sectional epidemiological study was carried out, using multi-stage sampling with conglomerates, in 1377 men from 15 to 49 years old. The mean age was 34.5 years (SD 7.5 years). Mean age at first sexual relations was 17.7 years (SD 2.8 years). The global proportion of condom use during the last sexual relation was 24.6%; use according to type of female sex partner in the last year was 18.8% with regular partners and 62.5% with occasional partners. The principal predictors of male condom use, identified through statistical modelling, were: younger age (<25 years), middle and high education level (>9 years), middle and high socioeconomic level and type of sexual partners (occasional and regular).

This population has risk factors for acquiring and transmitting some STDs, such as occasional sexual partners and a history of STDs. Characteristics which are important in relation to male condom use were identified, such as age (younger than 35), education (complete junior high school or more) and type of sexual partners (occasional and regular).

Factors Associated With Condom Use Among Sexually Active US Adults, National Survey of Family Growth, 2006-2010 and 2011-2013

BACKGROUND

Condom-less sex can increase the risk of acquiring or transmitting HIV.

AIM

To characterize the prevalence of condom use at the most recent sex act and identify factors associated with use of a condom at the most recent sex act in adults in the United States.

METHODS

Data from the cross-sectional National Survey of Family Growth from cycles 2006 through 2010 and 2011 through 2013 were analyzed for sexually active men and women 18 to 44 years old who reported having sex (vaginal, anal, or oral) with an opposite-sex partner in the past 12 months. HIV-related sexual risk behaviors (SRBs) in the past 12 months included sex with at least four opposite-sex partners; exchanging sex for money or drugs; sex with an injection drug user; sex with an HIV-positive person; sex with a man who previously had sex with a man (women only); sex with a man (men only); or sex with a partner who had sex with other partners.

OUTCOMES

The outcome for this analysis was condom use at the most recent anal or vaginal sex act.

RESULTS

Overall prevalence of condom use was 24.8%; only 33.8% of adults with at least one SRB reported the use of a condom. Only 46.4% of unmarried or single men (vs 14.7% married or cohabitating men) and 32.3% unmarried or single women (vs 14.1% married or cohabitating women) with SRBs reported using a condom at the most recent sexual encounter and were less likely to use a condom at the most recent sexual encounter compared with those who did not report SRBs. We did not find a significant relation between using a condom and SRBs in married or cohabitating men and women.

STRENGTHS AND LIMITATIONS

Our analysis adds to the literature on how condom use varies by marital status. We measured the use of condoms at the most recent sexual act, which might not reflect an individual's previous behavior of condom use. Nonetheless, condom use at the most recent sexual act has been documented in previous studies as a valid proxy of condom use over time.

CONCLUSION

Continued efforts are needed to promote condom use in heterosexual adults in the United States, particularly those at high risk for HIV, namely individuals engaging in anal sexual acts and with multiple sex partners.

Research Participants' Perceptions of the Certificate of Confidentiality's Assurances and Limitations

The certificate of confidentiality (COC) provides additional protections to personal and sensitive research data. COC guarantees are not absolute and investigators are obligated to inform potential participants of COC limitations. The present study utilized qualitative and partnership methodology to examine participants' (N = 24) perceptions of COC assurances and limitations in the context of a hypothetical study on depression. Although some participants were comforted by COC assurances, a majority of participants had confidentiality/privacy concerns specifically with COC passages concerning federal audits and legal reporting requirements. As one respondent noted, “Why is it that you guys don't have to turn the records over to the court unless I say so … but you have to give them over to the government?… I don't know about what is goin‘ on.” Our findings underscore the need for larger quantitative investigations to examine the negative and positive impact of COCs on research participation and response bias.

Why Common Sense Goes Out the Window: Effects of Alcohol on Intentions to Use Condoms

Four studies tested the hypothesis that alcohol decreases the likelihood of condom use during casual sex. First, in a correlational study, it was found that among men who reported that they usually use condoms, those who were intoxicated when they last had intercourse were less likely than sober men to have used one. Further, in two laboratory experiments and one field experiment, intoxicated people reported more positive intentions to have unprotected sex than sober people. These results are consistent with alcohol myopia as introduced by Steele and associates the notion that alcohol decreases cognitive capacity, such that intoxicated people are more likely to attend to the most salient cues in a situation. Intoxicated people may focus on the perceived benefits of having intercourse rather than on the negative consequences of not using condoms. These studies provide strong evidence that alcohol causes a decrease in condom use and suggest a mechanism for that relationship.

Discrepancies between HIV prevention communication attitudes and actual conversations about HIV testing within social and sexual networks of African American men who have sex with men

BACKGROUND

Promoting communication among African American men who have sex with men (AA MSM) and their social networks about HIV testing is an avenue for altering HIV prevention social norms. This study examined the attitudes of AA MSM on talking with peers about HIV testing and characteristics of their network members with whom they have these conversations.

METHODS

Data came from a cross-sectional survey of 226 AA MSM who were 18 years or older and self-reported sex with another male in the prior 90 days. Participants completed an inventory to characterize network members with whom they had conversations about HIV testing and HIV status.

RESULTS

Most of the sample reported that it was important/very important to talk to male friends about HIV (85%) and that they were comfortable/very comfortable talking with their friends about sexual behaviors (84%). However, a small proportion of the social network had been talked to by the participant about HIV testing (14%). Among sexual networks, 58% had been talked to about their HIV status, and this was positively associated with main and casual partner type compared with partners with whom money or drugs were exchanged.

CONCLUSIONS

Findings suggest that positive attitudes about communication may be necessary but not sufficient for actual conversations to occur. Designing interventions that increase communication with social networks is warranted.

Impact of alcohol on sexual decision making: Intentions to have unprotected sex

The impact of alcohol on intentions to have sex with a new partner and the antecedents of intentions were investigated in three studies (N = 139, 60, and 218, respectively). In all three studies, respondents were intoxicated or not intoxicated with alcohol and completed measures based on the Theory of Planned Behaviour in relation to having sex whilst imagining him- or her-self in the scenario. The scenario described unprotected sex between two individuals not in an existing relationship. Consistently across studies, intoxication had a significant effect on intentions for men but not for women. Also consistently across studies, affective attitudes were significantly stronger determinants of intentions for women than for men. Alcohol intoxication consistently moderated the impact of affective attitudes on intentions in women but not men, with greater intoxication associated with stronger impacts (Studies 1, 2, and 3). Implications for understanding the impacts of alcohol intoxication on sexual decision making in men and women are discussed.

Community-based implementation and effectiveness in a randomized trial of a risk reduction intervention for HIV-serodiscordant couples: study protocol

Background

The HIV/AIDS epidemic continues to disproportionately affect African American communities in the US, particularly those located in urban areas. Despite the fact that HIV is often transmitted from one sexual partner to another, most HIV prevention interventions have focused only on individuals, rather than couples. This five-year study investigates community-based implementation, effectiveness, and sustainability of ‘Eban II,’ an evidence-based risk reduction intervention for African-American heterosexual, serodiscordant couples.

Methods/design

This hybrid implementation/effectiveness implementation study is guided by organizational change theory as conceptualized in the Texas Christian University Program Change Model (PCM), a model of phased organizational change from exposure to adoption, implementation, and sustainability. The primary implementation aims are to assist 10 community-based organizations (CBOs) to implement and sustain Eban II; specifically, to partner with CBOs to expose providers to the intervention; facilitate its adoption, implementation and sustainment; and to evaluate processes and determinants of implementation, effectiveness, fidelity, and sustainment. The primary effectiveness aim is to evaluate the effect of Eban II on participant (n = 200 couples) outcomes, specifically incidents of protected sex and proportion of condom use. We will also determine the cost-effectiveness of implementation, as measured by implementation costs and potential cost savings. A mixed methods evaluation will examine implementation at the agency level; staff members from the CBOs will complete baseline measures of organizational context and climate, while key stakeholders will be interviewed periodically throughout implementation. Effectiveness of Eban II will be assessed using a randomized delayed enrollment (waitlist) control design to evaluate the impact of treatment on outcomes at posttest and three-month follow-up. Multi-level hierarchical modeling with a multi-level nested structure will be used to evaluate the effects of agency- and couples-level characteristics on couples-level outcomes (e.g., condom use).

Discussion

This study will produce important information regarding the value of the Eban II program and a theory-guided implementation process and tools designed for use in implementing Eban II and other evidence-based programs in demographically diverse, resource-constrained treatment settings.

Biases for affective versus sexual content in multidimensional scaling analysis: an individual difference perspective

Visual sexual stimuli can motivate sexual behaviors that can risk or enhance health. How one allocates attention to a sexually motivating stimulus may be important for predicting its effect on sexual feelings, sexual risk behaviors, and sexual problems. A large sample (N = 157) of men and women rated the similarity of all possible pairs of photographs of women, which had been pretested to vary in their sexual and affective content. Multidimensional scaling was used to extract two dimensions of sex and affect, including the extent to which each person relied on each dimension in making their similarity judgments. These individual weights were then used to predict sexual variables of interest. Participants who relied more on the affect information judging photograph similarity were more likely to be female, viewed erotica less frequently, reported fewer sexual partners, reported less sexual desire, and more sexual problems. Those who relied more on the erotic content in making their similarity judgments were more likely to be male, viewed more erotica weekly, experienced higher sexual desire, and were more likely to have taken an HIV test. The "double edge sword" of attention weight to affect in sexual cues is discussed for its potential to both enhance and harm sexual health.

Mediation effects of problem drinking and marijuana use on HIV sexual risk behaviors among childhood sexually abused South African heterosexual men

HIV/AIDS prevalence in South Africa is one of the highest in the world with heterosexual, transmission predominantly promoting the epidemic. The goal of this study is to examine whether, marijuana use and problem drinking mediate the relationship between histories of childhood sexual, abuse (CSA) and HIV risk behaviors among heterosexual men. Participants were 1181 Black men aged, 18-45 from randomly selected neighborhoods in Eastern Cape Province, South Africa. Audio computer assisted, self-interviewing was used to assess self-reported childhood sexual abuse, problem drinking, and marijuana (dagga) use, and HIV sexual transmission behavior with steady and casual partners. Data were analyzed using multiple meditational modeling. There was more support for problem, drinking than marijuana use as a mediator. Findings suggest that problem drinking and marijuana use, mediate HIV sexual risk behaviors in men with histories of CSA. Focusing on men with histories of CSA, and their use of marijuana and alcohol may be particularly useful for designing strategies to reduce, HIV sexual transmission in South Africa.

Cluster-randomized controlled trial of an HIV/sexually transmitted infection risk-reduction intervention for South African men

OBJECTIVES

We tested the efficacy of a sexual risk-reduction intervention for men in South Africa, where heterosexual exposure is the main mode of HIV transmission.

METHODS

Matched-pairs of neighborhoods in Eastern Cape Province, South Africa, were randomly selected and within pairs randomized to 1 of 2 interventions based on social cognitive theory and qualitative research: HIV/sexually transmitted infection (STI) risk-reduction, targeting condom use, or attention-matched control, targeting health issues unrelated to sexual risks. Sexually active men aged 18 to 45 years were eligible. The primary outcome was consistent condom use in the past 3 months.

RESULTS

Of 1181 participants, 1106 (93.6%) completed the 12-month follow-up. HIV and STI risk-reduction participants had higher odds of reporting consistent condom use (odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.03, 1.71) and condom use at last vaginal intercourse (OR = 1.40; 95% CI = 1.08, 1.82) than did attention-control participants, adjusting for baseline prevalence. No differences were observed on unprotected intercourse or multiple partnerships. Findings did not differ for sex with steady as opposed to casual partners.

CONCLUSIONS

Behavioral interventions specifically targeting men can contribute to efforts to reduce sexual risk behaviors in South Africa.

Norms governing urban African American adolescents' sexual and substance-using behavior

Using a probability-based neighborhood sample of urban African American youth and a sample of their close friends (N = 202), we conducted a one-year longitudinal study to examine key questions regarding sexual and drug using norms. The results provide validation of social norms governing sexual behavior, condom use, and substance use among friendship groups. These norms had strong to moderate homogeneity; and both normative strength and homogeneity were relatively stable over a one-year period independent of changes in group membership. The data further suggest that sex and substance using norms may operate as a normative set. Similar to studies of adults, we identified three distinct "norm-based" social strata in our sample. Together, our findings suggest that the norms investigated are valid targets for health promotion efforts, and such efforts may benefit from tailoring programs to the normative sets that make up the different social strata in a given adolescent community.

Procedures for an instrument development study: the Botswana experience

BACKGROUND

Health protective sexual communication (HPSC) between sexual partners can contribute to human immunodeficiency virus (HIV) prevention, but women face difficulties with HPSC because of cultural and gender issues.

PURPOSE

To present the procedures for an instrument development study conducted in Botswana between 2006 and 2008 on different aspects of HPSC. The study was guided by the theory of planned behaviour constructs.

METHODS

A literature review and a qualitative pilot study among young women aged 18-35 years in Gaborone city clinics generated items for the measures. Eleven measures were developed and evaluated for content validity. The measures were translated and evaluated by three typical participants for cultural relevance and acceptance. A quantitative pilot among ten women and a larger quantitative study among 280 other young women followed in 13 Gaborone city clinics for internal consistency reliability, and construct validity based on principal components analysis. All women who met selection criteria consented and responded to all questions. Research protocols were strictly adhered to.

RESULTS

Eight measures were reliable, with Cronbach's alphas between 0.69 and 0.95. Underlying factors were extracted for these. Two measures were unreliable, one with spuriously low reliability due to its brevity. Some significant relationships were identified between measures. DISCUSSION OF FINDINGS: The results highlighted the importance of HPSC, the significant influence of the male sexual partners and other relatives, and the need to integrate HPSC at all levels of HIV/acquired immunodeficiency syndrome prevention and research, focusing on the effectiveness of HPSC.

Adolescent health-risk sexual behaviors: effects of a drug abuse intervention

Adolescents who abuse substances are more likely to engage in health-risking sexual behavior (HRSB) and are at particularly high risk for HIV/AIDS. Thus, substance abuse treatment presents a prime opportunity to target HIV-risk behaviors. The present study evaluated a one-session HIV-risk intervention embedded in a controlled clinical trial for drug-abusing adolescents. The trial was conducted in New Mexico and Oregon with Hispanic and Anglo adolescents. Youths were randomly assigned to individual cognitive behavior therapy (CBT) or to an integrated behavioral and family therapy (IBFT) condition, involving individual and family sessions. The HIV-specific intervention was not associated with change. IBFT and CBT were both efficacious in reducing HIV-risk behaviors from intake to the 18-month follow-up for high-risk adolescents. For low-risk adolescents, CBT (versus IBFT) was more efficacious in suppressing HRSB. These data suggest that drug abuse treatments can have both preventative and intervention effects for adolescents, depending on their relative HIV-risk.

The relative role of perceived partner risks in promoting condom use in a three-city sample of high-risk, low-income women

We examined the effect of women’s perceptions of sexual partner risks on condom use. Women from three US cities (n = 1,967) were recruited to provide data on HIV risks. In univariate models, increased odds of condom use were associated with perceiving that partners had concurrent partners and being unaware of partners': (a) HIV status, (b) bisexuality, (c) concurrency; and/or (d) injection drug use. In multivariate models, neither being unaware of the four partner risk factors nor perceiving a partner as being high risk was associated with condom use. Contextual factors associated with decreased odds of condom use were having sex with a main partner, homelessness in the past year, alcohol use during sex, and crack use in the past 30 days. Awareness of a partner’s risks may not be sufficient for increasing condom use. Contextual factors, sex with a main partner in particular, decrease condom use despite awareness of partner risk factors.

One session of TTM-tailored condom use feedback: a pilot study among at-risk women in the Bronx

There is an urgent need to implement interventions to curb the spread of sexually transmitted infections (STIs), especially HIV. Consistent condom use is an effective preventive strategy, yet especially among those at highest risk, condom use remains too low. This paper describes changes in condom use and stages of condom use over two-three months time following a single session with an interactive multimedia computer-delivered Transtheoretical Model (TTM)-tailored expert system originally designed for at-risk adolescents. The intervention provided immediate TTM-tailored feedback to diverse urban women based on their stage of condom use and other TTM variables. Previous work found this system was acceptable. These data showed that 89% of women returned for a second session two-three months later, further supporting this system's utility. After just one feedback session, 21% of women not using condoms at baseline started using condoms consistently at follow-up, with a trend for a relationship to baseline stage of condom use. These results support further randomized controlled research on the reach and efficacy of computer-based TTM-tailored and individualized condom use interventions.

National Institute of Mental Health Multisite Eban HIV/STD Prevention Intervention for African American HIV Serodiscordant Couples: a cluster randomized trial

BACKGROUND

Human immunodeficiency virus (HIV) has disproportionately affected African Americans. Couple-level interventions may be a promising intervention strategy.

METHODS

To determine if a behavioral intervention can reduce HIV/sexually transmitted disease (STD) risk behaviors among African American HIV serodiscordant couples, a cluster randomized controlled trial (Eban) was conducted in Atlanta, Georgia; Los Angeles, California; New York, New York; and Philadelphia, Pennsylvania; with African American HIV serodiscordant heterosexual couples who were eligible if both partners were at least 18 years old and reported unprotected intercourse in the previous 90 days and awareness of each other's serostatus. One thousand seventy participants were enrolled (mean age, 43 years; 40% of male participants were HIV positive). Couples were randomized to 1 of 2 interventions: couple-focused Eban HIV/STD risk-reduction intervention or attention-matched individual-focused health promotion comparison. The primary outcomes were the proportion of condom-protected intercourse acts and cumulative incidence of STDs (chlamydia, gonorrhea, or trichomonas). Data were collected preintervention and postintervention, and at 6- and 12-month follow-ups.

RESULTS

Data were analyzed for 535 randomized couples: 260 in the intervention group and 275 in the comparison group; 81.9% were retained at the 12-month follow-up. Generalized estimating equation analyses revealed that the proportion of condom-protected intercourse acts was larger among couples in the intervention group (0.77) than in the comparison group (0.47; risk ratio, 1.24; 95% confidence interval [CI], 1.09 to 1.41; P = .006) when adjusted for the baseline criterion measure. The adjusted percentage of couples using condoms consistently was higher in the intervention group (63%) than in the comparison group (48%; risk ratio, 1.45; 95% CI, 1.24 to 1.70; P < .001). The adjusted mean number of (log)unprotected intercourse acts was lower in the intervention group than in the comparison group (mean difference, -1.52; 95% CI, -2.07 to -0.98; P < .001). The cumulative STD incidence over the 12-month follow-up did not differ between couples in the intervention and comparison groups. The overall HIV seroconversion at the 12-month follow-up was 5 (2 in the intervention group, 3 in the comparison group) of 535 individuals, which translates to 935 per 100,000 population.

CONCLUSION

To our knowledge, this is the first randomized controlled intervention trial to report significant reductions in HIV/STD risk behaviors among African American HIV serodiscordant couples.

Long-term effects of drug prevention on risky sexual behavior among young adults

OBJECTIVE

This study assesses the impact of a school-based drug prevention program, called Project ALERT, on risky sexual behavior among 1901 nonmarried, sexually active young adults who participated in one of two program variations as adolescents. It also tests for differences in program effect depending on program duration (middle school only vs. a combined middle school and high school program) and participants' gender.

METHODS

Using survey data from a randomized controlled experiment conducted in 45 midwestern communities (55 schools), we assessed program effects on risky sexual behavior at age 21 with three measures-having unprotected sex because of drug use plus engaging in inconsistent condom use and having sex with multiple partners.

RESULTS

Compared to control, Project ALERT reduced the likelihood of all risky sex outcomes except inconsistent condom use among these sexually active young adults, effects that occurred 5 and 7 years after program exposure. Program effects were partially mediated by reductions in alcohol and drug abuse. There were no significant differences in program effects by gender or by program duration compared to control. Implications for future prevention programs and research are discussed.

Improving epidemiological surveys of sexual behaviour conducted by telephone

BACKGROUND

This study assesses the impact of Telephone Audio Computer-Assisted Self-Interviewing (T-ACASI) on the reporting of sensitive (mainly heterosexual) behaviours.

METHODS

A randomized experiment was embedded in a telephone survey that drew probability samples of the populations of the USA (N = 1543) and Baltimore city (N = 744). Respondents were randomly assigned to have questions asked either by a T-ACASI computer or by a human telephone interviewer.

RESULTS

Compared with interviewer-administered telephone surveys, T-ACASI obtained more frequent reporting of a range of mainly heterosexual behaviours that were presumed to be sensitive, including recency of anal sex [adjusted odds ratio (A-OR) = 2.00, P < 0.001), sex during menstrual period (A-OR = 1.49, P < 0.001), giving oral sex (A-OR = 1.40, P = 0.001) and receiving oral sex (A-OR = 1.36, P = 0.002), and sexual difficulties for the respondent (A-OR = 1.45, P = 0.034) and their main sex partner (A-OR = 1.48, P = 0.0). T-ACASI also obtained less frequent reporting that respondent had a 'main sex partner' (A-OR = 0.56, P = 0.011) and discussed contraception prior to first sex with that sex partner (A-OR = 0.82, P = 0.094). For both males and females, T-ACASI obtained more frequent reports of first vaginal sex occurring at early ages (before ages 12 through 15). 'For males only', T-ACASI also elicited more frequent reports that first vaginal sex had 'not' occurred at later ages (i.e. by ages 20 through 24).

CONCLUSION

T-ACASI increases the likelihood that survey respondents will report sensitive heterosexual behaviours.

Women's knowledge, attitudes, and intentions concerning Human Papillomavirus vaccination: findings of a waiting room survey of obstetrics-gynaecology outpatients

OBJECTIVE

To assess women's knowledge, attitudes, and behaviours related to Human Papillomavirus (HPV) and HPV vaccination.

METHODS

A self-administered questionnaire was completed by 98 women (90.7% response rate) attending a hospital-based obstetrics and gynaecology outpatient clinic in a mid-size Ontario city.

RESULTS

Women had a moderate level of knowledge of general HPV-related issues, but lacked information about the ability of barrier contraception to prevent HPV and about characteristics of HPV vaccination. Women were strongly supportive of HPV vaccination for both male and female teenagers, but reported low levels of intention to receive vaccination themselves. Physician recommendation was the most influential factor in women intention to be vaccinated, and younger women were more likely to say they intended to be vaccinated. HPV-related knowledge, level of education, and number of previous sexual partners were unrelated to women's intentions to receive HPV vaccination.

CONCLUSION

Findings indicate that women's knowledge about HPV vaccination is inconsistent, that women are supportive of vaccinating both male and female teenagers, and that physician recommendation and younger age are associated with women's interest in receiving the vaccine.

T-ACASI reduces bias in STD measurements: the National STD and Behavior Measurement Experiment

BACKGROUND

Although telephone surveys provide an economical method for assessing patterns of diagnosed sexually transmitted diseases (STDs) and STD-related behaviors in populations, the requirement that respondents report such information to human telephone interviewers introduces an opportunity for substantial reporting bias. Telephone computer-assisted self-interviewing (T-ACASI) surveys substitute a computer for human interviewers when asking sensitive questions.

METHODS

A randomized experiment was embedded in a telephone survey that drew probability samples of the populations of the United States (N = 1543) and Baltimore city (N = 744). Respondents were randomly assigned to have sensitive questions asked either by a T-ACASI computer or by a human telephone interviewer.

RESULTS

Respondents interviewed by a T-ACASI computer were more likely to report STD symptoms [dysuria, genital sores, genital discharge, and genital warts; adjusted odds ratios (ORs) = 1.5-2.8] and a diagnosis of gonococcal or chlamydial infection during the past year (adjusted ORs = 3.6 and 6.1). T-ACASI respondents with a main sex partner in the past year were more likely to report that their partner has had an STD (adjusted OR = 2.4). For some measurements, the impact of T-ACASI was strongest among younger and less-educated respondents. When sampling weights were applied to project National STD and Behavior Measurement Experiment results to the populations of the United States and Baltimore, we found that reliance on data obtained by human interviewers would underestimate the annual incidence of chlamydial and gonococcal infections in these populations by factors of 2.4 to 9.7.

CONCLUSIONS

Compared with human telephone interviewers, T-ACASI surveys obtain increased reporting of STD symptoms, infections, and STD-related behaviors.

A brief decisional balance intervention increases motivation and behavior regarding condom use in high-risk heterosexual college men

Male college students constitute one of a number of at-risk populations susceptible to receiving and transferring sexually transmitted infections. Interventions designed to increase condom use have produced mixed results, but increasing motivation to use condoms may decrease risky sexual behavior. The current study examined the decisional balance, a component of Motivational Interviewing (MI), as an intervention to promote condom use. A total of 41 college men at-risk for negative outcomes from both unsafe sex and drinking participated. They reported both infrequent condom use and heavy drinking. Immediately following a decisional balance on condom use, three separate measures of motivation to change condom use increased. Further, participants reported increases in actual condom use at a 30-day follow-up. Participants did not alter their drinking behavior or their motivation to decrease problematic alcohol use. The findings provide preliminary support for the efficacy of a brief decisional balance intervention to increase safer-sex motivation and behaviors, but similar designs with true control groups receiving assessment only and larger numbers of participants are required before they can be generalized to the greater population of college students. College health professionals might adopt similar brief motivational enhancement interventions with the decisional balance to promote safer sex among at-risk college students.

Sex in Australia: Injecting and sexual risk behaviour in a representative sample of adults

OBJECTIVE

Some blood-borne and sexually transmissible agents may be spread by using non-sterile injecting equipment and by unprotected sexual intercourse. The objective of this study was to describe the prevalence of these risk factors in the general population of Australia.

METHODS

Computer-assisted telephone interviews were completed by a representative sample of 10,173 men and 9,134 women aged 16-59 years. The overall response rate was 73.1% (69.4% men, 77.6% women).

RESULTS

3% of respondents had ever injected non-prescription drugs; men were more likely than women to have done so. Predictors of injecting in men and women included being aged 20-29, homosexual or bisexual identity, and lower levels of education and income. Injecting was not more common in cities than elsewhere. Among people who had injected in the past year, 12.4% had shared needles and 43.0% had shared other paraphernalia. Sharing was significantly related to lower income. Unprotected sex with casual partners was more common in heterosexual activity than in male homosexual activity. Among heterosexually active respondents, 3.3% reported unprotected vaginal sex with casual partners (59% of those with such partners) and among homosexually active males 2.1% reported unprotected anal sex with casual partners (12% of those with such partners). Predictors of unprotected sex included indices of lower socio-economic status.

CONCLUSION

Sexual and injecting risks are reported by substantial minorities of the Australian population and are associated with indices of lower socio-economic status and bisexual identity. Programs are needed to address vulnerabilities to these infections.

Sex in Australia: The rationale and methods of the Australian Study of Health and Relationships

OBJECTIVE

To describe the methods and process of the Australian Study of Health and Relationships.

METHODS

A computer-assisted telephone interview was developed and applied to a stratified sample of the Australian population. After initially weighting to reflect the study design, the sample was further weighted to reflect the location, age and sex distribution of the 2001 Census.

RESULTS

Interviews were completed with 10,173 men and 9,134 women aged 16-59 years from all states and Territories. The overall response rate was 73.1% (69.4% among men and 77.6% among women). After accounting for the survey design and weighting to the 2001 Census, the sample appears broadly representative of the Australian population.

CONCLUSION

The combination of methods and design in the Australian Study of Health and Relationships, coupled with the high response rate, strongly suggests that the results of the study are robust and broadly representative of the Australian population.

The multinational Men's Attitudes to Life Events and Sexuality study: the influence of diabetes on self-reported erectile function, attitudes and treatment-seeking patterns in men with erectile dysfunction

AIMS

To identify the prevalence of erectile dysfunction (ED) in men with diabetes, and to compare the perceptions of ED and the treatment-seeking behaviour of these men with men with ED without diabetes.

METHODS

Phase I of this multinational study involved 27,839 men who were questioned about a number of men's health issues including ED, diabetes and cardiovascular conditions (i.e. hypertension, high cholesterol and angina). Epidemiological associations between these conditions were explored. Phase II involved 2912 men with self-reported ED, aged 20-75 years. Participants completed questionnaires concerning their ED, efforts to seek treatment for their ED, and potential influences that might affect treatment-seeking behaviour. Comparison of these responses was made between men with ED and diabetes and men with ED without diabetes.

RESULTS

There was a clear association between self-reported ED and diabetes, hypertension, angina and high cholesterol. Men with diabetes were more likely to consider their ED to be severe and permanent and to speak to a physician or a nurse about their ED, compared with men without diabetes. Sildenafil use was similar in both groups, but men with diabetes were more likely to have discontinued use, mainly because of the lack of treatment efficacy.

CONCLUSION

Men with diabetes were more likely to consider their ED to be severe and permanent, compared with men without diabetes. Furthermore, men with diabetes were more likely to discontinue sildenafil therapy, primarily because of poor efficacy. These findings suggest a need for alternative treatments for ED, especially in men with diabetes.

Estimated benefits of transplantation of kidneys from donors at increased risk for HIV or hepatitis C infection

Kidneys from organ donors who have behaviors that place them at increased risk for infection with human immunodeficiency virus (HIV) or hepatitis C virus (HCV) are often discarded, even if viral screening tests are negative. This study compared policies that would either 'Discard' or 'Transplant' kidneys from Centers for Disease Control classified increased-risk donors (CDC-IRDs) using a decision analytic Markov model of renal failure treatment modalities. Base-case CDC-IRDs were current injection drug users (IDUs) with negative antibody and nucleic acid testing (NAT) for HIV and HCV, comprising 5% of kidney donors. Compared to a CDC-IRD kidney 'Discard' policy, the 'Transplant' policy resulted in higher patient survival, a greater number of quality-adjusted life-years (QALYs) (5.6 vs. 5.1 years per patient), more kidney transplants (990 vs. 740 transplants per 1000 patients) and lower cost of care ($60 000 vs. $71 000 per QALY). The total number of viral infections was lower with the 'Transplant' policy (13.1 vs. 14.8 infections per 1000 patients over 20 years), because the 'Discard' policy led to more time on hemodialysis, with a higher HCV incidence. We recommend that kidneys from NAT-negative CDC-IRDs be considered for transplantation since the practice is estimated to be beneficial from both the societal and individual patient perspective.

Ethnic differences in decisional balance and stages of mammography adoption

Behavioral theories developed through research with mainstream, English-speaking populations have been applied to ethnically diverse and underserved communities in the effort to eliminate disparities in early breast cancer detection. This study tests the validity of the transtheoretical model (TTM) decisional balance measure and the application of the TTM stages of change in a multiethnic, multilingual sample. A random sample of 1,463 Filipino, Latino, African American, Chinese, and White women aged 40 to 74 completed a phone survey of mammography beliefs and practices. Consistent with the TTM and independent of ethnicity, decisional balance was associated with mammography stage in all five ethnic groups when controlling for socioeconomic and other factors. In addition, having private insurance and a regular physician and being a long-time resident in the United States were positively associated with mammography maintenance. The application of the TTM for mammography is supported in a multiethnic and multilingual sample.

Predictors of participation in an HIV risk reduction intervention for socially deprived Latino women: A cross sectional cohort study

BACKGROUND

Little is known about predictors of participation and attrition in HIV prevention programs for socially deprived Latino women.

OBJECTIVES

The purpose of this study was to examine factors that predict program participation and attrition among Latino women in a community-based, culturally specific HIV risk reduction intervention.

DESIGN

This was a cross-sectional comparison of baseline data drawn from a randomized HIV risk reduction trial.

SETTINGS

Information was drawn from study subjects residing in a predominately Latino low-income community in Chicago.

PARTICIPANTS

Among 404 study subjects in the intervention group, 214 of Latino women who had attended at least 5 of 6 intervention sessions were considered participants. One hundred and twelve women who never attended and 29 of women who attended fewer than 3 sessions were considered dropouts.

METHODS

The baseline data of program participants were compared to those of dropouts. The influence of the following factors on program participation was examined: sociodemographic characteristics, self-esteem, HIV knowledge, intimate partner violence, depression, and communication with partner.

RESULTS

Logistic regression analysis showed that Mexican women were more likely to participate in the intervention program than Puerto Rican women (odds ratio (OR)=1.88, 95% confidence interval (CI)=1.64, 4.23). Other significant predictors of program participation included: being older (OR=1.08, 95% CI=1.03, 1.14), unemployed (OR=0.46, 95% CI=0.25, 0.83), having higher risk reduction behavior intentions score (OR=1.16, 95% CI=1.06, 1.26), and lower level of depressive symptoms (OR=0.97, 95% CI=0.95, 0.99).

CONCLUSIONS

The recruitment and retention strategies should be developed by considering those important predictors of intervention participation to prevent Latino women from dropping out of the HIV prevention program.

Risky sexual behavior in low-income African American women: the impact of sexual health variables

In a sample of 163 low-income African American women, we used logistic regression analyses to test for associations between (a) 5 operationalized constructs theorized in the Sexual Health Model to impact one's overall sexual health (barriers to healthy sexuality, sexual anatomy and functioning, positive sexuality, sexual health care, and cultural identity) and (b) several measures of risky sexual behavior (consistent condom use, multiple concurrent partnerships, and overall sexual risk). No significant relationship was found between acculturation and risky sexual behaviors. Having sexual difficulties was positively associated with overall sexual risk and multiple concurrent partnerships. Favorable attitudes toward condoms were positively associated with consistent condom use. Desiring or intending pregnancy was positively associated with inconsistent condom use and overall sexual risk behavior This is only the second study linking sexual difficulties and risky sexual behavior The exact nature of this correlational relationship needs to be studied and replicated in different and more heterogeneous populations.

Polymerase chain reaction detection of Y chromosome sequences in vaginal fluid: preliminary studies of a potential biomarker for sexual behavior

BACKGROUND

Self-reported measures of sexual behavior are subject to nontrivial reporting biases.

OBJECTIVE

The objective of this study was to develop a behavioral biomarker of recent sexual activity among females that is inexpensive, easily administered, and can be used in low sexually transmitted disease prevalence populations.

METHODS

We developed a polymerase chain reaction (PCR) assay to detect Y chromosome (Yc) fragments. The Yc primers were developed against a 200-basepair (bp) microsatellite repeat sequence, which is unique to the male genome. A standard PCR technique was used. Assay sensitivity was determined quantitatively using donated semen samples. To assess longevity of detectability, we recruited female subjects in monogamous relationships. Seventeen subjects had unprotected intercourse followed by 3 weeks of abstinence from vaginal intercourse. Self-administered vaginal swabs (SAVS) were collected every other day. In addition to the swabs, subjects kept daily sexual diaries. Swabs were processed by semiquantitative PCR, and Yc decay curves were determined for each subject. The half-life of Yc in vaginal fluid was calculated on the collection of individual decay curves by a random-effects regression model approach.

RESULTS

The sensitivity of our Yc-PCR assay was determined to be 5 copies of Yc. In the longevity studies, Yc was detectable in SAVS up to 15 postcoital days (PCD). Mean Yc DNA concentration in SAVS eluate followed an exponential decay pattern for each subject. Mean concentrations were 66.7 ng/mL at PCD-1, 20.6 ng/mL at PCD-7, and 4.5 ng/mL at PCD-15. The estimated half-life for Yc clearance was 3.83 days.

CONCLUSION

The swab-based Yc-DNA PCR assay can detect coitus in women for a 2-week retrospective period. This can be used to validate sexual behavior-reporting and condom use in women and promises to be a useful tool in sexual behavior research.

Evaluating the potential impact of vaginal microbicides to reduce the risk of acquiring HIV in female sex workers

OBJECTIVES

The following questions were addressed: would the introduction of vaginal microbicides substantially reduce the risk of female sex workers (FSWs) acquiring HIV? Which factor would it be most important to maximize, microbicide efficacy or microbicide use? What level of microbicide efficacy and use would be necessary to counterbalance a possible reduction in condom use?

DESIGN

Mathematical modeling, with parameter estimations from available literature.

METHODS

Risk equations were developed and Monte Carlo simulations were performed to model a FSW's daily risk of HIV acquisition currently, and after, microbicide introduction. Uncertainty and sensitivity analyses were used as well as tornado plots for two ranges of microbicide efficacy (30-50%) and (50-80%). Risk was estimated for FSWs whose clients sometimes (10-50%) use condoms, and those whose clients never use condoms. An analytical threshold for which reducing condom use increases risk was estimated.

RESULTS

For both groups of FSWs, daily risk would decrease by approximately 17% or approximately 28% using 30-50% or 50-80% effective microbicides, respectively. Increasing microbicide use would have greater impact on reducing risk than increasing microbicide efficacy. The microbicide efficacy and usage required to ensure that 'condom replacement' does not increase a FSW's risk of acquiring HIV was calculated.

CONCLUSIONS

Microbicides could substantially reduce FSWs' risk of acquiring HIV; absolute decrease in risk would be greatest in high-prevalence regions. The public health impact of microbicides will depend upon usage and efficacy. Even if the microbicides that become available are only low-to-moderately effective, the probability that risk in FSWs will increase (due to replacing condoms with microbicides) is low.

Isolating the nexus of substance use, violence and sexual risk for HIV infection among young adults in the United States

Adults aged 18 to 29 are at significant sexual risk for HIV infection. Substance use and violence are known to be associated with sexual risk in certain groups, but few studies have examined these relationships in the general population of young adults. No studies have tested whether the contributions of substance use and violence to sexual risk are independent, and few have looked at whether drug use associations with risk are specific to certain substances. Using structural modeling techniques, we examined data for 3,437 adults aged 23-24, testing for associations between three measures of sexual risk for HIV, various forms of substance use, victimization and partner violence. Alcohol use and victimization predicted high risk sex in independent samples of single and married/cohabiting adults. Marijuana use, problem drug use, and partner violence were inconsistently related to sexual risk across measures and subsamples. HIV-prevention interventions designed for young adults in the general population should target individuals who use alcohol frequently and who are victims of violence, and should address both factors, in addition to sexual risk behavior.

Reasons for unsafe sex among a community sample of people with HIV/AIDS

In a sample of 117 HIV positive men and women, 34 (29%) were identified as engaging in risky sexual behavior in the past six months and were asked for reasons they did so. Analysis using broad categories revealed that partner-related reasons and hedonistic reasons were the most frequent reasons overall (71%). More male (87%) than female (60%) responses were captured by those two categories. Differences by partner status, viral load and age were not as pronounced. Specific interventions and intervention frameworks are suggested.

Calculating the Contribution of Herpes Simplex Virus Type 2 Epidemics to Increasing HIV Incidence: Treatment Implications

Herpes simplex virus type 2 (HSV-2) is the most prevalent sexually transmitted pathogen worldwide. There is considerable biological and epidemiological evidence that HSV-2 infection increases the risk of acquiring HIV infection and may also increase the risk of transmitting HIV. Here, we use a mathematical model to predict the effect of a high-prevalence HSV-2 epidemic on HIV incidence. Our results show that HSV-2 epidemics can more than double the peak HIV incidence; that the biological heterogeneity in susceptibility and transmission induced by an HSV-2 epidemic causes HIV incidence to rise, fall, and then rise again; and that HSV-2 epidemics concentrate HIV epidemics, creating a "core group" of HIV transmitters. Our modeling results imply that findings from HSV-2 intervention trials aimed at reduction of HIV incidence will be variable and that positive findings will be obtained only from trials in communities in which HIV incidence is steeply rising.

Managing the sexually transmitted disease pandemic: a time for reevaluation

The serious implications of the sexually transmitted disease (STD) pandemic that currently challenges educators, medical practitioners and governments suggest that prevention strategies, which primarily focus on barrier protection and the management of infection, must be reevaluated and that initiatives focusing on primary prevention of behaviors predisposing individuals to STD risk must be adopted. Human immunodeficiency virus/acquired immunodeficiency syndrome, human papillomavirus, genital herpes, and Chlamydia are used to illustrate the pervasive presence of STDs and their serious consequences for individuals and national infrastructures. Long-term sequelae are discussed, including the emerging link between various sexually transmitted infections and cancer, and the psychosexual and psychosocial factors which impact infected individuals. Although risk reduction and treatment of existing infection is critical, the promotion of optimal life-long health can be achieved most effectively through delayed sexual debut, partner reduction, and the avoidance of risky sexual behaviors.

Seropositive individuals willingness to communicate, self-efficacy, and assertiveness prior to HIV infection

The purpose of this study was to examine possible communication similarities between human immunodeficiency virus (HIV) positive and HIV negative individuals. Forty HIV positive heterosexuals, who were infected through heterosexual sex, completed an on-line questionnaire to assess their safer sexual communication, willingness to communicate, condom self-efficacy, and assertiveness prior to HIV infection. Results indicate that prior to infection, HIV positive heterosexuals reported having similar safer sexual communication behaviors to those not infected with the virus. Participants in this study reported high levels of willingness to engage in safer sex communication, but low levels of actual communication. Further, results reveal that participants who engaged more often in safer sex communication were more likely to use condoms. Additionally, participants reported high levels of condom self-efficacy and moderate levels of assertiveness; both variables positively correlated with condom use. Finally, participants reported that they believed they did not need to discuss using condoms because they were not at risk. Previous safer sexual communication research reveals HIV negative individuals reported engaging in the same behaviors and holding the same beliefs reported by seropositive individuals. Hence, discussion of the importance of safer sexual communication and the utility of personalization to increase the communication of HIV negative individuals is explored.

The Multinational Men's Attitudes to Life Events and Sexuality (MALES) Study Phase II: Understanding PDE5 Inhibitor Treatment Seeking Patterns, among Men with Erectile Dysfunction

OBJECTIVE

The aim of Phase II of the Men's Attitudes to Life Events and Sexuality (MALES) Study is to explore PDE5 inhibitor treatment seeking among men with erectile dysfunction (ED).

METHODS

Phase II of the MALES study involved 2,912 men, aged 20-75 years, from 8 countries (U.S., U.K., Germany, France, Italy, Spain, Mexico, and Brazil), who reported ED. Participants were recruited from the MALES Phase I sample [1] and via booster methods (e.g., physician referral, street interception), and completed self-report questionnaires concerning the characteristics of their ED, their efforts to seek PDE5 inhibitor treatment for their sexual dysfunction, and attitudinal and referent influences that potentially affect treatment-seeking. Statistical analyses focus on identification of correlates of PDE5 inhibitor treatment seeking.

RESULTS

PDE5 inhibitor utilization is strongly associated with ED sufferers' assessment of the severity of their sexual dysfunction, with their belief that medication for ED is dangerous, and with their perceptions of whether physicians, other professionals, and spouses or family members are supportive of their seeking treatment. ED sufferers who evaluate their sexual dysfunction as severe, who believe that medication for ED is not dangerous, and who perceive support for treatment seeking from referent others, are more likely to utilize PDE5 inhibitor treatment.

CONCLUSION

Findings indicate that perceived ED severity, beliefs about ED medication, and referent influences are strongly correlated with utilization of PDE5 inhibitor therapy. These findings aid our understanding of factors that may incline men with ED to seek-or to avoid-PDE5 inhibitor therapy for their sexual dysfunction, and provide a basis for clinical and educational interventions to assist men with ED to seek appropriate treatment.

Reduction in sexual risk behaviors and infection rates among African Americans and Mexican Americans

BACKGROUND

Project SAFE, a gender- and culture-specific cognitive-behavioral intervention, was one of the few interventions to have demonstrated a significant reduction in sexually transmitted infections in a randomized, controlled trial.

GOAL

We evaluated intervention efficacy in 379 Mexican Americans and 170 African Americans; and in a subset of 477 women, explored ethnic differences in the relationships over time between attitudes/beliefs about relationships, reported sexual behavior, and infection.

STUDY DESIGN

Women were questioned intensively at baseline, 6, and 12 months. We used stratified analyses and multivariate regression to evaluate ethnic differences and the role of behavior in explaining ethnic differences in infection.

RESULTS

African Americans had higher overall infection rates (29.0% vs. 18.3%) than Mexican Americans, but the intervention efficacy was similar (odds ratios, 0.58 and 0.54, respectively). African Americans reported more douching after sex, less mutual monogamy, and more rapid partner turnover. However, Mexican Americans appeared slightly more likely to have sex with an untreated partner, and there was no difference in risky sex. African Americans reported greater difficulty finding partners and reported attitudes more compatible with nonmonogamy.

CONCLUSIONS

Despite substantial ethnic differences in attitudes/beliefs, behaviors, and infection rates, the intervention had a comparable impact on both Mexican American and African American.
