Alcohol and risky sex: in search of an elusive connection

Delineating patterns of sexualized substance use and its association with sexual and mental health outcomes among young gay, bisexual and other men who have sex with men in Singapore: a latent class analysis

BACKGROUND

Young gay, bisexual, and other men who have sex with men (YMSM) are vulnerable to the risks associated with sexualized substance use. This is a novel study in Singapore that aims to classify patterns of sexualized substance use among YMSM, and investigate its association with sexual and mental health outcomes.

METHODS

In this cross-sectional study among 570 YMSM aged 18 to 25 years old, latent class analysis (LCA) conducted to identify classes with similar patterns of sexualized substance use, across which measures of inconsistent condom use, recent STI diagnoses, past suicide ideation and depression severity were compared.

RESULTS

LCA revealed three classes of YMSM based on types of substances ever used in sexualized contexts, which we labelled as 'substance-naive', 'substance-novice', and 'chemsex'. Substance-naive participants (n = 404) had only ever used alcohol, while substance-novice participants (n = 143) were primarily amyl nitrite users with a small proportion who reported using chemsex-related drugs. Chemsex participants (n = 23) comprised individuals who had mostly used such drugs. Those in the chemsex group were more likely to report recent unprotected anal sex with casual partners (aPR = 3.28, 95%CI [1.85, 5.79]), depression severity (aβ = 3.69, 95%CI [0.87, 6.51]) and a history of suicide ideation (aPR = 1.64, 95%CI [1.33, 2.03]).

CONCLUSIONS

Findings of this study highlight how the use of varying substances in sexualized contexts may be classified and characterized by different sexual and mental health outcomes. Health promotion efforts should be differentiated accordingly to address the risks associated with sexualized substance use among YMSM.

Social capital and chemsex initiation in young gay, bisexual, and other men who have sex with men: the pink carpet Y cohort study

Background

Young gay, bisexual, and other men who have sex with men (YMSM) are especially vulnerable to the risks associated with sexualized substance use, or ‘chemsex’. Engaging in chemsex established as a major risk factor for Human Immunodeficiency Virus (HIV) acquisition, and is thus a public health issue of increasing urgency. This paper attempts to explore the association between measures of social capital and patterns of sexualized substance use among a sample of YMSM in Singapore.

Methods

Results of this study were derived from baseline data of the Pink Carpet Y Cohort Study in Singapore, comprising a sample of 570 HIV-negative YMSM aged 18 to 25 years old. Latent class analysis was employed to identify classes with similar patterns of sexualized substance use, and multinomial logistic regression was employed to examine associations between class membership and proxy measures of social capital, including age of sexual debut, bonding and bridging social capital, connectedness to the lesbian, gay, bisexual and transgender community, and outness.

Results

Latent class analysis revealed three classes of YMSM based on their histories of sexualized substance use, which we labelled as ‘alcohol’, ‘poppers’, and ‘chemsex’. Multivariable analyses revealed that participants who were older (aOR = 1.19, p = 0.002) and who identified as gay (aOR = 2.43, p = 0.002) were more likely to be in the poppers class compared to the alcohol class. Participants with a later age of sexual debut were increasingly less likely to be in the poppers (aOR = 0.93, p = 0.039) and chemsex classes (aOR = 0.85, p = 0.018), compared to the alcohol class.

Conclusions

Varying measures of social capital such as an earlier age of exposure to sexual networks may predispose YMSM to greater opportunities for sexualized substance use. Future interventions should target YMSM who become sexually active at an earlier age to reduce the risks associated with sexualized substance use.

When Women Imbibe

The present research examines how alcohol, or even the illusion of imbibing alcohol, affects women's perceived self-efficacy for avoiding HIV. Women ( N= 82) were randomly assigned to one of four conditions in a 2 (alcohol or no alcohol) × 2 (expect alcohol or not) balanced placebo design. After consuming alcoholic or nonalcoholic beverages, participants assessed their self-efficacy for HIV risk prevention. Both alcohol consumption and alcohol expectancy increased women's confidence that they could detect whether a potential partner was HIV positive simply by interacting with the potential partner.

Prevalence of Heavy Drinking and Risky Sexual Behaviors in Adult Emergency Department Patients

BACKGROUND

The study aim was to assess the prevalence and co-occurrence of alcohol and sexual risk behaviors among emergency department (ED) patients in community hospitals.

METHODS

Systematic screening of ED patients (N = 6,486; 56.5% female) was conducted in 2 community hospitals in the northeast during times with high patient volume, generally between the hours of 10 AM to 8 PM, Monday through Saturday. Screening occurred from May 2011 through November 2013. Assessment included validated measures of alcohol use and sexual risk behavior.

RESULTS

Overall results identified high rates of alcohol use, sexual risk behaviors, and their co-occurrence in this sample of ED patients. Specifically, ED patients in between the ages of 18 and 35 were consistently highest in hazardous alcohol use (positive on the Alcohol Use Disorders Identification Test or endorsing heavy episodic drinking [HED]), sexual risk behaviors, and the co-occurrence of alcohol and sex-risk behaviors.

CONCLUSIONS

Findings show a high co-occurrence of hazardous drinking and unprotected sex among ED patients and highlight the role of HED as a factor associated with sexual risk behavior. Efforts to integrate universal screening for the co-occurrence of alcohol and sexual risk behavior in ED settings are warranted; brief interventions delivered to ED patients addressing the co-occurrence of alcohol and sexual risk behaviors have the potential to decrease the risk of sexually transmitted infections and HIV among a large number of patients.

Substance use among male sex workers in Vietnam: prevalence, onset, and interactions with sexual risk

BACKGROUND

HIV research in Vietnam has focused primarily on its large heroin injector population. Data on men who have sex with men [MSM], particularly the large and growing population of men who exchange sex for money or other material rewards, male sex workers [MSWs], is very limited.

METHODS

Data derive from a cross-sectional study of MSW, age 16-35, recruited using community sampling methods in three cities in 2010-2011, including Hanoi, Ho Chi Minh City [HCMC], and Nha Trang City (n=710). Assessments included demographic characteristics, substance use, sexual risk, and use of health services. A series of "event" questions were used to assess the influence of alcohol and drugs on sexual risk.

RESULTS

Both tobacco and alcohol are initiated at a young age and most participants currently use both substances overall across all three cities. While alcohol and tobacco use precede the initiation of sex work, stimulant and opiate use are initiated following the initiation of sex work. There was substantial overlap between substance use and sexual risk, and this overlap was strongest in sexual events involving male and female elective partners rather than sex work clients.

CONCLUSION

Although rates of HIV infection in this group are low, this may be an artifact of the young age of the sample. High rates of drug use, including alcohol, tobacco and illicit drugs, coupled with high rates of ulcerative STIs such as HPV, suggest the potential for rapid amplification of STI/HIV risk among MSW and their complex sex partnering networks.

Alcohol misuse and multiple sexual partners

INTRODUCTION

We examine the association between self-reported alcohol misuse and alcohol use within 2 hours of having sex and the number of sexual partners among a sample of African-American and Latino emergency department (ED) patients.

METHODS

Cross-sectional data were collected prospectively from a randomized sample of all ED patients during a 5-week period. In face-to-face interviews, subjects were asked to report their alcohol use and number of sexual partners in the past 12 months. Data were analyzed using multiple variable negative binomial regression models, and effect modification was assessed through inclusion of interaction terms.

RESULTS

The 395 study participants reported an average of 1.4 (standard error = 0.11) sexual partners in the past 12 months, 23% reported misusing alcohol, and 28% reported consuming alcohol before sex. There was no statistically significant association between alcohol misuse and the number of sexual partners; however, alcohol before sex was associated with a larger number of sexual partners in the past year. Moreover, among those who misused alcohol, participants who reported alcohol before sex were 3 times more likely to report a higher number of sexual partners (risk ratio = 3.2; confidence interval [CI] =1.9-5.6). The association between alcohol use before sex and number of sexual partners is dependent upon whether a person has attributes of harmful drinking over the past 12 months. Overall, alcohol use before sex increases the number of sexual partners, but the magnitude of this effect is significantly increased among alcohol misusers.

CONCLUSION

Alcohol misusers and those who reported having more than 1 sexual partner were more likely to cluster in the same group, ie, those who used alcohol before sex. Efforts to reduce the burden of sexually transmitted diseases, including human immunodeficiency virus, and other consequences of risky sexual behavior in the ED population should be cognizant of the interplay of alcohol and risky sexual behaviors. EDs should strive to institute a system for regular screening, brief intervention, and referral of at-risk patients to reduce negative consequences of alcohol misuse, including those of risky sexual behaviors.

Randomized controlled trial of brief interventions to reduce college students' drinking and risky sex

The present study tested the proposition that an intervention to reduce alcohol use among college students will also reduce their risky sexual behavior. In a randomized controlled trial, 154 heavy-drinking, predominantly White, heterosexual college students at behavioral risk for infection with HIV and other sexually transmitted diseases were assigned to receive no intervention or a two-session, in-person, motivational interviewing-based intervention focused on (a) reducing alcohol risk behavior, (b) reducing HIV risk behavior, or (c) reducing both alcohol and HIV risk behavior. Three-month retrospective assessments of alcohol use and sexual behavior were conducted at intake and at 3-, 6-, 9-, 12-, and 15-month follow-up appointments. During follow-up, participants who received the single-focus alcohol risk-reduction intervention drank less frequently and consumed fewer drinks per drinking day as compared with no-intervention control participants, but did not differ from control participants in their frequency of intercourse without a condom or number of sexual partners. Participants who received the single-focus HIV risk-reduction intervention evidenced fewer unprotected sex events during follow-up, as compared with control participants. The number of sexual partners reported during follow-up did not differ by condition. Effects of the interventions did not vary significantly over time and were not moderated by participant gender. Results suggest that intervening to reduce alcohol use may not reduce risky sexual behavior among nonminority college students, but that a brief motivational intervention targeting HIV risk behavior may have utility for reducing the frequency of unprotected sex in this population.

Event-level marijuana use, alcohol use, and condom use among adolescent women

BACKGROUND

It is widely believed that marijuana use and alcohol use directly intercede on successful condom use. However, measurement differences and inconsistent findings in past research remain unclear whether marijuana and alcohol work directly to influence condom behavior, or spuriously function through other factors that actually reflect an increased likelihood of vaginal sex. The current study prospectively disentangles the association of marijuana and alcohol use on condom behavior among adolescent women.

METHODS

Young women (N=387; 14-17 years) provided daily sexual diaries as part of a longitudinal cohort study (1999-2009) of sexual behavior and sexual relationships. To separate the effects of marijuana and alcohol use on vaginal sex from condom use (when vaginal sex occurs), we estimated a 3-category outcome variable (no vaginal sex, vaginal sex with a condom, vaginal sex without a condom), alternating no sex (Model 1) and sex without a condom (Model 2) as the referent categories. Generalized estimating equation multinomial logistic regression adjusted odds ratios for multiple sexual events from the same young woman over time.

RESULTS

Subjects contributed 14,538 coital events; 30% of these events were condom-protected. Neither marijuana nor alcohol use was directly associated with lower condom use; the strongest effect of condom use (adjusted odds ratio) and nonuse was performance of these behaviors in the past week.

CONCLUSIONS

This study finds no evidence of a relationship between marijuana or alcohol use and condom nonuse. Both condom use and nonuse were identified as consistent behavioral patterns, regardless of the effect of marijuana and alcohol use.

Seroconversion in context

This paper describes the accounts that homosexually active men give of their HIV seroconversion and interrogates these accounts for risk discourses. In particular, this paper asks whether the risk discourses of HIV researchers and educators are present in the men's narratives of their own seroconversion. Such discourses make reference to 'unsafe' sex--particularly the practice of unprotected anal intercourse, numbers of sexual partners or 'promiscuity', and the disinhibiting effect of drugs and alcohol. The data are drawn from an ongoing case-series study of seroconversion in which men who had seroconverted were asked to give an account of the occasion on which they believe they were infected. A number of themes were identified in the men's accounts. The men's descriptions of what they believe to be the seroconversion event indicate that their attributions, i.e., the reasons they give for their HIV infection, vary depending on the context. Within regular relationships, breakdown of negotiated safety, love and intimacy, and fatalism were among the explanations given. Seroconversion attributed to casual sexual encounters was more likely to be explained in terms of pleasure, lack of control, and with reference to particular sexual settings. The ways in which men understood their HIV infection were informed both by the risk discourse of HIV researchers and also by the discourses of love and pleasure, as well as that of control.

HIV risk reduction among detained adolescents: a randomized, controlled trial

OBJECTIVES

Criminally involved adolescents engage in high levels of alcohol-related risky sex. A theory-based sexual and alcohol risk-reduction intervention was designed, implemented, and evaluated in juvenile detention facilities.

PARTICIPANTS AND METHODS

In a randomized, controlled trial, 484 detained adolescents received 1 of 3 group-based interventions: combined sexual and alcohol risk reduction (group psychosocial intervention [GPI] + group motivational enhancement therapy [GMET]); sexual risk reduction only (GPI); or HIV/sexually transmitted disease prevention information only (group information-only intervention [GINFO]). Follow-up data were obtained 3, 6, 9, and 12 months after the intervention. Behavioral outcomes were condom-use behavior, frequency of intercourse while drinking, and alcohol-related problems.

RESULTS

Condom-use behavior measured as frequency of condom use during sex (ranging from never to always) decreased over time, although the GPI and GPI + GMET interventions mitigated this tendency at the 3-, 6-, and 9-month follow-up assessments. Although both active interventions were significantly more successful than the GINFO condition and the pattern of effects favored the GPI + GMET, there were no statistically significant differences between the GPI and GPI + GMET interventions.

CONCLUSIONS

Findings support the feasibility of integrating alcohol-specific sexual risk content into a theory-based sexual risk-reduction intervention and provide additional evidence that theory-based interventions are effective at reducing risky sex in this population. There was limited evidence of intervention effects on alcohol-use outcomes. Future research should focus on strengthening the GPI + GMET to most effectively target risky sexual behavior among at-risk adolescents.

Accounts of HIV seroconversion among substance-using gay and bisexual men

Statistical associations between substance use and seroconversion among gay and bisexual men abound. However, these associations often ignore men's own interpretations of their seroconversion. Using in-depth interviews with gay and bisexual men who reported using drugs or alcohol at the time of their seroconversion, we identify how these men explain the events that led to HIV transmission. Whereas a small minority of respondents reported substance use to explain their seroconversion, the majority reported three competing explanations. These participants claimed that they lacked sufficient knowledge about the behavioral risks that led to their seroconversion; that their decision to engage in unsafe sex was because of negative personal affect; and that they "trusted the wrong person." We link these findings to prevention and suggest that gay and bisexual men who use substances for recreational purposes will benefit from prevention efforts designed to address issues of gay and bisexual men rather than substance-using men.

Alcohol use and risk of HIV infection among men who have sex with men

In the United States, men who have sex with men (MSM) currently represent more than 50% of those living with HIV and over 70% of HIV+ men (CDC 2007, http://www.cdc.gov/hiv/topics/msm/resources/factsheets/pdf/msm.pdf ). Male-to-male sexual contact has been identified as the predominant route of transmission among this sub-group, which underscores the need for research that targets risk factors associated with risky sex-related HIV acquisition. Along these lines, research has shown that one potentially important predictor variable for risky sex among MSM is alcohol use. The major aim of this paper is to review and integrate empirical evidence on the association of alcohol use and risky sex among MSM. A summary of the quantitative research is provided first, followed by a critique of the reviewed literature, a discussion of the consistency of the existing empirical evidence with predictions of current theories, and finally, recommendations for future research designed to evaluate alcohol-related sexual risk in MSM.

A discursive approach to disinhibition theory: the normalization of unsafe sex among gay men

HIV research and prevention commonly cite disinhibition theory as an explanation for HIV infection among gay men. Analyzing qualitative interview data in which men talk about recreational substance use and their safer sex practices, we interrogate the concept of disinhibition theory from a discursive perspective. From this perspective, we treat talk not as a route or resource to something presumed to lie beyond the talk, but as a form of action designed for its interactional context. We demonstrate how the men normalize unsafe sex through constructions of disinhibition as common and widespread. In doing so, the men manage accountability for their own experiences with foregoing condom use while using substances. Our analysis demonstrates the men's displayed concerns to avoid individualized explanations for having engaged in unprotected sex. This may explain why some gay men may resist HIV prevention campaigns, based on these very individualized explanations.

Drinking and condom use: results from an event-based daily diary

Although it is often assumed that drinking alcohol interferes with condom use, most studies on this topic do not meet the conditions required for causal interpretation. We examined the association of drinking to condom use using data from diaries of alcohol use and sexual encounters, collected over 8 weeks from college students and clients of a sexually transmitted disease clinic. This method establishes the temporal relationships between drinking and condom use and controls for individual differences by using a within-subjects analysis. Multilevel models that predicted condom use from alcohol use before the sexual encounter, partner type, and the use of other contraception showed that drinking before sex was unrelated to condom use. These results do not support the persistent notion that alcohol causes people to engage in sexual risk that they would avoid when sober; instead, people tend to follow their usual pattern of condom use, regardless of alcohol use.

Diary study of substance use and unsafe sex among adolescents with substance use disorders

PURPOSE

This study tested event-level associations between substance use and condom use, as well as potential covariates, among adolescents with substance use disorders (SUDs).

METHODS

A total of 134 adolescents (age, 15-21 y), 72% with SUDs, participated in telephone diary data collection of sexual events over a 6-week period. Effects on condom use of event-level substance use, partner type, salience of costs associated with unprotected sex, and subject-level SUD and sensation-seeking were tested in random intercept logistic regression models. A total of 637 sexual events were available for analysis.

RESULTS

Event-level alcohol and drug use as well as subject-level SUD and sensation-seeking were not associated with condom use in multivariate models. However, all other event-level measures were significant, including an interaction between partner type and salience of preventing acquired immune deficiency syndrome (AIDS). The importance of preventing AIDS was associated only with condom use with regular partners. Prevention of pregnancy was associated with condom use independent of partner type.

CONCLUSIONS

As in other event-level studies, substance use was not related to condom use in our study. Novel results in our study showed that the salience of preventing negative outcomes is a significant predictor of condom use even in the context of event-level substance use and partner type. These results suggest that prevention efforts for substance-using youth should not focus on preventing substance use as a way to prevent unsafe sex, but should emphasize the potential costs of unsafe sex even with known partners.

Sexual risk behaviour among undergraduate students in Enugu, Nigeria

This study aims to identify high-risk sexual behaviour among undergraduate students in a developing country and to formulate programmes targeted at reduction of complications of such risky sexual behaviour. This was a questionnaire survey taken of undergraduate students in four institutions of higher learning in Enugu, Nigeria over a 1-month period. The prevalence of sexual activity was 76.8%, with 85.4% of females and 62.3% of males having more than one sexual partner. More female students than their male counterparts (65.7% vs 42.2%) had their first sexual encounter as an adolescent. Sexual risk behaviour that includes having multiple sexual partners, not using a condom, anal and oral sex were more common among the lower social class, adolescents, females and those living off-campus. While economic reasons are a major factor that encourages risky sexual behaviour in the female, the urge to have sex and curiosity, tended to favour such sexual experimentation in the male. Despite a good knowledge of the complications that could follow such risky sex behaviour, the sex lives of the students remained unchanged. Educational and risk reduction programmes targeting a change in belief and behaviour is required to maintain sexual safety among these youth.

Sexual risk behaviors and substance use among alcohol abusing HIV-positive men who have sex with men

An ethnically diverse sample (79.0% men of color) of HIV seropositive (HIV+) men who have sex with men (MSM) with alcohol use disorders from the New York City metropolitan area was recruited from a variety of settings frequented by such men. Data were collected using quantitative assessments and calendar based techniques at the baseline assessment of a longitudinal study assessing the relationship between alcohol and substance use and sexual risk behaviors as well as alcohol use and HIV disease progression. Data were selected on a sample of 253 HIV+ MSM (mean age = 38.55, SD = 6.73). Of these, the majority of participants (80.2%, n=203) reported engaging in sexual behaviors with casual partners. In terms of sexual behaviors that put partners at greatest risk for HIV transmission, unprotected anal insertive intercourse was most likely to occur with unknown status casual partners (46.8%, n=95) than with either HIV negative casual partners (19.2%, n=39) or with HIV+ casual partners (40.8%, n=83). Further, bivariate analyses indicated significant relationships between the use of several substances and sexual behaviors that put partners at greatest risk for HIV transmission, as well as a significant positive relationship between drinks per drinking day and viral load.

Alcohol and condom use: a meta-analysis of event-level studies

BACKGROUND

Although it is often assumed that drinking alcohol interferes with condom use, studies on this topic have used several different methods and have yielded inconsistent findings. By examining drinking and condom use in specific sexual encounters, the role of alcohol in influencing unprotected intercourse is targeted.

GOAL

The goal of the study was to assess the relationship of alcohol use and condom use in discrete sexual encounters using meta-analysis.

STUDY DESIGN

Studies in the literature were identified by computerized searches of MEDLINE and PsycINFO and hand searches of reference lists. Summary odds ratios were calculated for all analyses and for subgroups formed according to type of sexual encounter (first, most recent, most recent with a new sexual partner).

RESULTS

The association of alcohol use and condom use varied by type of sexual encounter: drinking at first intercourse was associated with decreased condom use (odds ratio [OR], 0.54; 95% CI, 0.44-0.66), but drinking was unrelated to condom use in recent sexual encounters (OR, 1.04; 95% CI, 0.89-1.21) and in recent encounters with new partners (OR, 1.1; 95% CI, 0.92-1.32).

CONCLUSION

Drinking is not necessarily linked to unprotected intercourse; the relationship between alcohol use and unprotected sex depends on context and sexual experience of the partners.

Substance use and sexual transmission risk behavior of HIV-positive men who have sex with men

We examined substance use in relationship to transmission risk behavior (unprotected insertive, UIAI, or receptive anal intercourse, URAI) between HIV-positive men who have sex with men (MSM) and their HIV-negative or unknown serostatus partners. Men who engaged in transmission risk behavior with casual partners were more likely than men who did not engage in such behavior to have used various substances. Users of certain drugs were specifically less likely to use condoms with HIV-negative or unknown status partners than users. Of men who drank alcohol, those who drank more frequently before or during sex engaged in significantly more UIAI with casual partners. Of men who used drugs, those who used more frequently before or during sex were more likely to engage in URAI with casual partners. In multivariate analyses, use of inhalants as well as drinking before or during sex predicted UIAI, while use of inhalants as well as noninjection drug use before or during sex predicted URAI. HIV prevention programs for HIV-positive MSM should focus on decreasing substance use and use specifically before or during sex. Developing prevention programs for substance-using MSM is critical to improve community health and decrease HIV transmissions.

The relation of alcohol use to HIV-risk sexual behavior among adults with a severe and persistent mental illness

The authors examined the relationship between alcohol use and HIV-risk sexual behavior and tested whether alcohol use immediately prior to sex is related to decreased condom use. The participants were 159 adults living with a severe and persistent mental illness. Each participated in a structured interview to assess all sexual and drug-use behavior over a 3-month period. Analysis of 3,026 sexual behaviors reported by 123 sexually active participants indicated that at the global level, participants who drank more heavily were more likely to have engaged in sexual risk behavior. At the event level, however, alcohol use was not related to condom use during vaginal or anal intercourse; that is, participants who used condoms when sober tended to use them to the same extent when drinking.

Alcohol use and sexual behavior among "Black" adolescents

This paper reports on findings collected from 1993-1995 from an ethnographic interview study that investigated whether a pattern of HIV-related risk behavior varies across subpopulations of minority adolescents by studying behaviors and perceptions of risk for HIV infection among two ethnic groups of 314 Black adolescents-African-American and Haitian Blacks. Of those who had sex within the past 6 months and were current drinkers, 69% said they did not have sex after drinking. Although many of the adolescents believe that drinking has a disinhibitory effect and may be a factor in nonuse of condoms, alcohol is but one element in a constellation of factors related to sexual intercourse and condom use.

Substance use and risky sexual behavior among homeless and runaway youth

PURPOSE

To (a) characterize human immunodeficiency virus (HIV)-related risk behaviors of homeless youth; (b) determine whether substance use is associated with risky sexual behavior in this population; and, if so, (c) explore explanations for this relationship.

METHODS

A purposive sample of 327 homeless youth (ages 14-21 years) in Washington, DC, were surveyed in 1995 and 1996. Survey items were adapted from items used in a national study of adult substance use and sexual behavior and measured global (lifetime) and event-specific (most recent sexual encounter) behaviors.

RESULTS

Sexual activity with many partners, "survival" sex, and substance use were common. However, needle use was rare, and consistent condom use was evident in half the sample. Nearly all correlations between global measures of substance use and risky sex were statistically significant, but only a few of the event-specific correlations were significant. Marijuana use during the most recent sexual encounter was associated with nonuse of condoms, but this relationship disappeared in the multivariate model. However, crack use during the last encounter was associated with condom use; this relationship remained significant in the multivariate model. Lack of motivation to use condoms, longer histories of sexual activity and homelessness, symptoms of drug dependency, not discussing HIV risks with partner, and being female were also associated with nonuse of condoms.

CONCLUSIONS

Homeless youth do use condoms, even within the context of substance use and casual sex. Results suggest that prevention and targeted intervention efforts have had some positive effect on this population, but young homeless women are in need of targeted prevention. Finally, additional research is needed to investigate the observed relationship between crack use and condom use in this sample.

[Is there a correlation between alcohol drinking and sexual risk taking? A discussion of conceptional aspects exemplified by HIV infected men with homosexual behavior]

Does sexual risk behavior and alcohol consumption correlate or is sexual risk behavior due to alcohol consumption? These questions are controversially discussed in the literature. We investigated whether the two different methodological concepts (global association, e.g. not specific to the critical incident and situational association) cause these discrepancies in a sample of 64 HIV-infected gay men. There was no significant global association between alcohol consumption and sexual risk behavior. Using the situational approach, drinking was not related to sexual risk behavior. The combination of these two concepts may help to identify persons at risk.

Sex under the influence. A diary self-report study of substance use and sexual behavior among adolescent women

OBJECTIVE

To evaluate the potential causal relationship between alcohol and drug use and behavior that increases the risk of sexually transmitted diseases.

STUDY DESIGN

Longitudinal study conducted at a sexually transmitted diseases clinic and four community-based primary care clinics for adolescents. The participants were 82 female adolescents (age 16-19 years) who agreed to complete diaries recording each coital event. Subjects were participants in a larger study of prevention of reinfections by sexually transmitted organisms. The main outcome measure was condom use at each coital event. Predictor variables were usual pattern of condom use (when substances were not involved) and two event-specific measures: sex partner change and use of alcohol or drugs before intercourse.

RESULTS

Average time span of the diaries was 9.2 weeks. Subjects recorded 1,265 coital events. Ninety-three substance-associated coital events were recorded by 22 subjects. Event-specific condom use was associated with usual pattern of condom use, but not with event-specific variables of partner change or substance use before intercourse.

CONCLUSIONS

These data do not support the hypothesis that substance use causes alteration of adolescent women's behavior in a manner that increases risk of sexually transmitted diseases.

Is there a relationship between "heavy drinking" and HIV high risk sexual behaviors among general population subjects?

The authors investigated the association between "heavy drinking" and sexual behaviors among 2,581 general population subjects from the St. Louis Epidemiologic Catchment Area survey conducted from 1981 to 1983. Lifetime sexual behaviors included promiscuity, infidelity, receiving money for sex, and same gender sex. It was found that sexual behaviors were associated with lifetime heavy drinking. Regardless of gender, race, or age, "heavy drinkers" were significantly more likely to report each of the high risk sexual behaviors, except same gender sex, compared to "nonheavy drinkers." With the multiple logistic regression analyses it was found that "heavy drinking" non-Black females, Black males regardless of drinking history, "heavy drinking" males, and younger subjects regardless of drinking history were at higher risk to report the high risk sexual behaviors. This study confirms that there is a strong association between "heavy drinking" and high risk sexual behaviors in a midwestern population. This is the first study to find an association between alcohol drinking patterns and high risk sexual behaviors in the general population. Implications of these findings for public health education efforts are discussed.

Acculturation, sexual behavior, and alcohol use among Latinas

We explored the relationship of alcohol use to unsafe sex in Latinas. Telephone interviews were conducted with 523 currently sexually active Latinas aged 18-49 years. Only 7.5% of these women used alcohol half of the time or more prior to sex. "Regular" alcohol users had more sexual partners, but also had more experience with condom use, used condoms with primary partners as frequently as nonusers of alcohol, and used condoms more with secondary partners. While Latinas who use alcohol prior to sex more often have multiple sexual partners, alcohol use does not appear to interfere with condom use.

Coming out and AIDS-related high-risk sexual behavior

How the withdrawal of social support associated with the coming out of gay men influences AIDS-related sexual risk-taking among Flemish (Belgian) gay men is analyzed. Recruited via key persons, the 379 gay men in this nonclinical cohort completed a lengthy, computerized questionnaire dealing with diverse aspects of gay life and culture. Independent variables include demographic characteristics, AIDS knowledge, coming-out histories, six social support dimensions, and personal resources. The dependent variables were insertive and receptive anal intercourse with and without a condom. Stepwise regression explained, respectively, 41.2, 38.4, 18.4, and 14.2% of the variance. Absence of appraisal (the view that others approve of the way one does things or feels about things) led to higher frequencies of insertive anal sex (both with and without a condom). The experience of emotional conflict lowered the use of condoms by the insertive partner in anal intercourse. Disapproval by significant others of being gay also led to higher levels of receptive anal intercourse without a condom. Subjects with a high belief in mastery had higher frequencies of risk-taking, suggesting that the combination of the experience of negative reactions and high mastery lead to greater involvement in risky sexual behavior. Findings are interpreted within the theoretical framework of the coming-out process and gay identity formation.

Substance use and risky sexual behavior for exposure to HIV. Issues in methodology, interpretation, and prevention

Recent reports have suggested that the use of alcohol or drugs is related to sexual behavior that is high risk for HIV infection. If substance use leads to unsafe sexual activity, understanding the dynamics of this relationship can contribute to research and preventive and educational efforts to contain the spread of AIDS. In this article, we review research on the relationship between substance use and high-risk sexual behavior. We then consider the inherent limitations of the research designs used to study this relationship, outline some methodological concerns including measurement and sampling issues, and comment on causal interpretations of correlational research findings. We end with a consideration of potential avenues for future research and a discussion of implications of these findings for current AIDS prevention policies.

AIDS and promiscuity: muddles in the models of HIV prevention

AIDS has been blamed on promiscuity and the promiscuous, and a major goal of many HIV-prevention programs has been to induce people to reduce the number of their sexual partners. Despite the salience of this concept in the AIDS discourse of scientists, policymakers, the media, religious leaders, and the gay community, critical analysis of the role of promiscuity in this epidemic has been lacking. Following a review of promiscuity in various genres of AIDS discourse, this article discusses promiscuity in American society and in HIV-prevention campaigns. The relative risks associated with monogamy, abstinence and promiscuity are examined, and the author concludes that the partner-reduction strategy, instead of contributing to a reduction in HIV transmission has been an impediment to AIDS prevention efforts, exacerbating the problem by undermining the sex-positive approaches to risk reduction that have proven effective. Responsibility for this misguided strategy is attributed to a moralistic approach to AIDS and to the misapplication of epidemiological concepts and inappropriate social science models to the task of promoting healthy forms of sexuality.
