Sexual activity in HIV-positive African American crack cocaine smokers.

The AIDS epidemic in the United States continues to disproportionately affect minorities of color, especially African Americans. The purpose of this study was to explore the sexual behaviors of a sample of African American HIV positive crack smokers aware of their serostatus. Participants (100 men, 37 women) were included in this study based on the following criteria: a minimum age of 18 years, HIV positive serostatus, treatment with HIV antiretroviral medications for a minimum of 3 months prior to interview, crack cocaine use at least once in the 7 days prior to being interviewed, willingness to provide a urine sample to confirm recent drug use, and vaginal or anal sex at least once in the past 7 days. The questionnaire was a compilation of other reliable surveys and was designed to collect sociodemographic data, drug use, sexual behavior, condom use intentions and motivators, STD and HIV infection history, HIV medications, and adherence requirements. Participants reported having 1,266 different partners in the 30 days prior to the interview and had traded sex for money or drugs with 68%. A total of 79 participants had multiple partners and accounted for 1,247 partnerships. Rates of consistent condom use across partnerships were low, indicating that more interventions in this at-risk population are needed.

Multiple sexual partnerships in a sample of African-American crack smokers.

The sample for this study consisted of 692 sexually active African-American crack cocaine users living in Houston, TX who reported more than one sexual partner in the previous 30 days. Participants were asked to describe each of their two most recent partners from a list of eight choices: spouse/like a spouse/lover; close friend/friend/acquaintance/customer you like/customer. Analyses were conducted on the 1,384 partners and 692 partnership combinations reported. Partnerships and partnership patterns were examined with respect to three risk behaviors-unprotected sex, alcohol use to accompany sex, and drug use to accompany sex-and with respect to three affective measures-partner intimacy, condom use responsibility, and condom use self-efficacy. Results indicate that while many partnerships were based on trading sex for money or drugs, many participants reported partners they considered a spouse or friend. Risk behaviors and affective measures were found to differ by partner type.

A psychosocial comparison of New Orleans and Houston crack smokers in the wake of Hurricane Katrina.

The purpose of this study was to compare psychological distress in a sample of African American crack cocaine users who relocated to Houston from New Orleans after Hurricane Katrina to African American drug users resident in Houston. Fifty-four African Americans from New Orleans were compared to a sample of 162 people in Houston. Data were collected between June 2002 and December 2005. There were no significant differences between the two groups on either depression or anxiety, but the New Orleans sample scored higher on the self-esteem scale and scored slightly lower on the risk-taking scale.

Stages of consistent condom use, partner intimacy, condom use attitude, and self-efficacy in African-American crack cocaine users.

This study examined how condom use attitude, self-efficacy, and partner intimacy related to five stages of consistent condom use. Interview data were collected from sexually active, heterosexual, African-American crack cocaine smokers (N = 366). Dependent measures assessed both the participants' own responses and their perceptions about their last sex partner's own personal condom use attitude and participants' condom use self-efficacy expectations. Partner intimacy was assessed both as a continuous attitudinal and as a discrete relationship measure. Less than 10% were classified as consistent condom users. Two thirds of inconsistent users were in the Precontemplation (PC) stage. The contemplation (C) and preparation (P) stages were equal among the remainder of the inconsistent condom users. Higher partner intimacy reduced modestly readiness for consistent condom use. The stage but not the intimacy group was related to the condom use attitudes and self-efficacy measures. Last partners' perceived own negative attitudes were significantly related to the stages of consistent condom use and was especially low in the action (A) and maintenance (M) stages. Participants' own negative attitudes were unrelated to the stages. Of the self-efficacy measures, both participants' performance and situational condom use self-efficacies increased significantly after the PC stage and were highest in the P, A, and M stages. However, situational self-efficacy accounted for most of performance self-efficacy variance. In sum, consistent condom use was rare. A partner's attitudes and the participants' own situational self-efficacy expectations, rather than intimacy, determined the readiness to adopt consistent condom use.

Improving Condom Self-Efficacy and Use among Individuals Living with HIV: The Positive Choices Mapping Intervention.

Few interventions have been designed to improve behavioral outcomes and reduce risk of HIV transmission of individuals living with HIV, most focusing on preventative efforts directed at individuals who are HIV-negative. However, people living with HIV present individual and public health risks (infection with a different strain of HIV, health complications from contracting STD's, continued sexual activity with individuals with unknown HIV status) that have become the focus of intervention efforts. The current paper explores a promising new intervention, The Positive Choices Mapping intervention (PCM), designed to increase condom self-efficacy and use among African American crack cocaine smokers who are living with HIV. The intervention was grounded in Social Cognitive Theory and incorporated an empirically backed visual representation strategy (node-link mapping). The focus of the current paper is on the main components of the intervention.

Perceptions of risk in research participation among underserved minority drug users.

Research with underserved minority drug users is essential to quality health care and prevention. Understanding how participants perceive risk in research is necessary to inform research regulators so that research protections are neither lax, exposing participants to harm, nor overly stringent, thereby denying access to beneficial research. Data from 37 semistructured interviews of underserved, African-American crack cocaine users, collected from February to May 2006 in a large, urban setting, were analyzed using content analysis. In three hypothetical studies, participants recognized risks as relative and articulated and evaluated specific risks. Research regulators may enhance the accuracy of risk assessment in research by incorporating the views of participants. Study implications and limitations are noted. Future research on risk perception in research participation is suggested.

Decisions to participate in research: views of underserved minority drug users with or at risk for HIV.

Under-representation of minority populations, particularly African Americans, in HIV/AIDS research is problematic because African Americans bear a greater disease burden from HIV/AIDS. Studies of motivations for participating in research have emphasized factors affecting individuals' willingness to participate and barriers to participation, especially in regard to HIV vaccine research. Little is known about how underserved minority drug users perceive research and their decisions to participate. This study describes African American drug users' perceptions of research participation and their decisions to participate based on three kinds of hypothetical HIV/AIDS-related clinical studies. In-depth, qualitative interviews were conducted with 37 underserved, African American crack cocaine users, recruited from participants already enrolled in three different behavioral HIV prevention studies. Interviews were recorded, transcribed, coded for themes and sub-themes and analyzed using directed and conventional content analysis. Participants' decisions to take part in research often involved multiple motivations for participating. In addition, decisions to participate were characterized by four themes: a desire for information; skepticism and mistrust of research and researchers; perceptions of medical care and monitoring within a study; and participant control in decisions to participate or decline participation. Lack of adequate information and/or medical care and monitoring within a study were related to mistrust, while the provision of information was viewed by some individuals as a right and acknowledgement of the participant's contribution to the study. Participants perceived, rightly or wrongly, that medical monitoring would control some of the risks of a study. Participants also described situations of exerting control over decisions to enter or withdraw from a research study. Preliminary findings suggest that continuous communication and provision of information may enhance enrollment and adherence. Further exploration of decisions to participate in research will add to the understanding of this complex phenomenon and enhance the ability of individuals with HIV/AIDS to benefit from research.

A cluster analysis of drug use and sexual HIV risks and their correlates in a sample of African-American crack cocaine smokers with HIV infection.

The purpose of this cross-sectional study was to classify a sample of HIV-seropositive African-American crack cocaine smokers into homogenous HIV drug use and sexual risk groups using a two step multivariate cluster analysis. Two hundred and fifty-eight crack cocaine smokers participated in the study. Cluster analysis revealed three distinct HIV risk groups. The highest risk group, the largest one, was characterized by frequent, daily crack use, multiple sex partners, trading sex, and inconsistent condom use. The consistent condom use group, the smallest group, was characterized by consistent condom use. The inconsistent condom use group, the second largest group, was distinguished by inconsistent condom use. Comparisons of the three HIV risk groups revealed that the highest risk group had a higher proportion of illegal sources of income, higher proportion of binged crack use, frequent, daily, alcohol use, same gender sex partners, and scored higher on depressive symptoms. Members of the consistent condom use group were more likely to have been HIV diagnosed for a shorter time, to have HIV serodiscordant casual sex partners, higher psychological motivation for condom use, and a lower frequency of vaginal sex. Members of the inconsistent condom use group were more likely to have a main sex partner, to be married, to be on public assistance, to know the HIV serostatus of their casual partner, and less likely to conceal their HIV serostatus. An alarming finding was that a large number of participants inconsistently used condoms with HIV serodiscordant sex partners. Interventions aiming to prevent the secondary spread of HIV infection in African-American crack cocaine smokers should take this variability in account and focus on the differences.

Perceptions of financial payment for research participation among African-American drug users in HIV studies.

BACKGROUND: Financial compensation for participating in research is controversial, especially when participants are recruited from economically disadvantaged and/or marginalized populations such as drug users. Little is known about these participants' own views regarding payment for research participation. OBJECTIVE: The objective of the study was to elicit underserved minority drug users' views about monetary payments for participating in research. DESIGN: Semi-structured in-depth interview study of motivations for and perceptions of participation in research was used. PARTICIPANTS: Thirty-seven adult, economically disadvantaged African-American crack cocaine smokers were the participants of the study. APPROACH: Participants were recruited from among those taking part in three HIV prevention studies. Interviews were conducted at one of 2 research field offices located in underserved minority neighborhoods in Houston, Texas. Interviews lasting 30-45 min were recorded, transcribed, coded, and analyzed for categories and themes using both conventional and directed qualitative content analysis. This report addresses themes under the broad category of financial motivations for participating in research. RESULTS: Participants viewed monetary payment for research as essential to attract participation and desirable to provide optional income. Payment for research participation was perceived as one potential income source among others. Participants considered self-determination a prerogative for themselves and others. They rejected the notion of payment for participation as encouraging drug use or as inducing risk taking. CONCLUSIONS: Research regulators should consider participants' views of their desires and capacity for autonomous decisions about financial compensation for research rather than assume participants' diminished capacity due to poverty and/or drug use. Payment for research participation appears to be part of the "informal economy" that has been observed in underserved communities.

Characteristics, drug use, and sex partners of a sample of male sex workers.

Some male sex workers (MSWs) are also engaging in a significant amount of illicit drug use and other high risk behavior. The purpose of this study was to examine demographic characteristics, HIV risk behaviors, and sex partner characteristics in a sample of MSW. Data were collected from 179 men who were trading sex for money in Houston, TX. In the past 30 days they reported an average of 56 male partners and 5 female partners. Of the 179 men, 152 had been tested for HIV and knew their status. Twenty-six percent of those tested had tested positive.

Psychological correlates of trading sex for money among African American crack cocaine smokers.

This article compares demographic characteristics, sexual practices, and psychosocial status among 193 African American female crack cocaine users who currently, previously, or never traded sex for money. Current traders were less likely to have a main sexual partner, more likely to have a casual sexual partner, and more likely to smoke larger quantities of crack. There was a significant trend towards current traders reporting lower self-esteem, greater depression and anxiety, poorer decision-making confidence, more hostility, less social conformity, greater risk taking behaviors, and more problems growing up, compared to previous and never traders. These differences suggest that interventions should address self-esteem, risk-taking practices, depression and anxiety as well as other psychosocial factors.

HIV prevention and street-based male sex workers: an evaluation of brief interventions.

The purpose of this study was to evaluate the acceptability and the comparative efficacy of brief HIV risk reduction interventions to increase condom use during paid anal sex by street-based male sex workers (MSWs). Of the 399 street-based MSWs who participated in the evaluation of acceptability, 112 participated in the evaluation of efficacy. Acceptability was evaluated by assessing completion rates. Intervention efficacy was assessed across two brief interventions, a "standard" and a "standard-plus" interventions. The primary outcome of concern was condom use during paid anal sexual encounters. In addition to this variable, changes in drug use, needle use, condom use beliefs, and condom use intention were also assessed. Results showed that almost two thirds of MSWs enrolled in a brief intervention completed it. Completion rates varied by age, race/ethnicity, sexual orientation, and HIV status. Condom use during paid anal sex increased postintervention. In addition, condom use intentions, positive condom use outcome expectations, and condom use normative expectations increased preintervention to postintervention. However, there were no significant differences between the standard and the standard-plus brief interventions in any of the outcomes measured. Brief interventions to reduce the HIV risks are acceptable to MSWs and are efficacious for reducing unprotected anal sex during paid sexual encounters.

Male heterosexual crack smokers with multiple sex partners: between- and within-person predictors of condom use intention.

Little research has examined predictors of condom intention within concurrent partnerships. This study examined predictors of intention among 259 male African-American crack smokers with multiple partners. Each participant reported personal condom intention at next sex, condom use self-efficacy, responsibility and outcome expectances for himself and his perceptions for his last two sex partners. Stepwise logistic regressions showed that for both partners one and two, condom use at last sex and personal responsibility for condom use were predictors of intention to use condoms at next sex. Perceived partner responsibility was an additional positive predictor with Partner 2. Hierarchical generalized linear model analyses showed that positive intention was associated negatively with perceived partner responsibility and intimacy, while positively related to situational self-efficacy. Personal responsibility interacted with intimacy such that only men who indicated the highest levels of intimacy were more likely to intend to use condoms. Overall, the findings in this study support the need for examining additional social cognitive constructs that capture the interpersonal aspects of sexual relationships such as personal and perceived responsibility, intimacy and how beliefs may change between multiple partners and across time. Finally, the differences in the valence of perceived partner responsibility across analyses and the interaction of personal responsibility with intimacy suggest the need for studies that include measure of power within the relationship.

An investigation of concurrent sex partnering in two samples of drug users having large numbers of sex partners.

The objective of this study was to quantitatively measure the nature of concurrent sex partnering in two samples of drug users having large numbers of sex partners. The purpose of this study was to measure concurrent sex partnering and overlap in concurrent sex partners in two samples of drug users in which some or all participants were trading sex-for-money. Two samples having large numbers of sex partners were used to conduct the analyses: drug-using male sex workers (MSW) and male and female crack cocaine smokers (CS) having vaginal sex. To reflect the quality of concurrent partnering, three measures were used: the proportion of the samples having concurrent partners; the proportions of the samples having intimate, casual, and sex-for-money of partners; and overlap in concurrent partners. Proportions of each sample having concurrent partners were essentially the same. However, the kinds of concurrent partners and overlap in concurrent partners were significantly different. Concurrent partners in the MSW sample were mostly sex-for-money or sex-for-drugs partners. Most concurrent partners in the CS sample were initimate or casual sex partners. Overlap in concurrent partners was also significantly different. The measure of overlap for the CS sample was three times higher than that of the MSW sample. These data suggest that concurrent sex partnering in the two samples, beyond the proportion having concurrent partners, was different. The patterns of concurrent sex partners in each sample may reflect different reasons for engaging in concurrent partnering. Different reasons for engaging in concurrent partnering may also be reflected in different overlap scores between the two samples. Efforts should be made in future studies to better capture the complexities of concurrent partnering and to examine the implications of these for disease spread and control.

Spatial bridging in a network of drug-using male sex workers.

This study sought to determine whether drug-using male sex workers (MSWs) spatially bridge sexual networks across cities and to determine whether the behaviors of MSWs who bridge differ from the behaviors of those who do not. Data were collected from 42 MSWs in Houston, Texas, between May 2003 and February 2004. Spatial bridging was defined as having traded sex for money in another city before traveling to and trading in Houston. Cities bridged by MSWs were geographically plotted and were primarily located in the Gulf Coast and in Florida. Slightly less than half of MSWs were identified as spatially bridging from one city to another. A significantly higher proportion of MSWs who bridged cities were homosexual (55% vs. 23%) and HIV positive (31% vs. 5%). Those who bridged cities used marijuana and injected drugs more frequently and had significantly more male sex partners than MSWs who did not bridge cities. Despite the small sample size, this study found that many drug-using MSWs spatially bridge sexual networks in cities where they trade sex for money.

Medication compliance and satisfaction with treatment for HIV disease in a sample of African-American crack cocaine smokers.

The development of treatment regimes for African-American HIV-infected crack cocaine users has often been based on assumptions about compliance with medication regimes rather than evidence. This study sought to obtain baseline information on the adherence to antiretroviral medications by members of this important risk population in Houston, Texas. It was found that for only 5 of a range of 16 antiviral medications was there a significant correlation between levels of compliance reported by respondents and their beliefs as to how effective these medications are. Medication compliance was also found not to be associated with frequency of crack cocaine use in the month prior to interview. Furthermore, irrespective of both gender and their reported extent of medication compliance, the respondents tended to report positive relationships with their treating physician, with higher levels of satisfaction reported by women. These results suggest that the majority of African-American crack cocaine users are able to comply with HIV treatment regimes, with more than half (53%) claiming full compliance for one or more medications, and a further one third (31%) claiming compliance more than half the time. Moreover, these findings suggest that they will continue to take antiretroviral medications even if they have doubts about the effectiveness of these medications.

Situational correlates of condom use in a sample of African-American drug users who are primarily crack cocaine users.

We studied the situational determinants of condom use for vaginal sex in 151 African-American crack cocaine users in Houston, Texas, using situational presentation (Sitpres) methodology, which uses hypothetical scenarios with randomly generated levels of eight variables across 10 scenarios that may impact the decision to use a condom. Multiple regression showed that variables associated with a high probability of using a condom were older age, how badly the partner wants to use a condom, and how badly the respondent wants vaginal sex. Crack craving or level of intoxication were not correlates. The Sitpres methodology was successfully used by these crack users and data indicated that it was sexual variables, rather than drug-associated variables, that were significantly associated with condom use.

Condom use behaviors in HIV-infected African American crack cocaine users.

The purpose of this study was to investigate sexual risk behaviors and factors associated with consistent condom use of HIV+ African Americans receiving HAART who smoke crack. Participants were African Americans in Houston, Texas and over 18, being treated for HIV, and reported currently using crack. Measures included demographic variables, sexual behaviors, drug use, and nine psychosocial scales and seven escape scales. One hundred thirty seven participated in the study. Condom use was low across all partner types. Regression analyses revealed two demographic variables, and two psychosocial and one escape scale were significantly associated with intention to use condoms. One of the more alarming findings of this study concerns the large number of individuals who know they are HIV positive yet continue to have unprotected sex. The inconsistent condom use by these HIV+ individuals threatens the progress that has been made to stem the epidemic.

Drug injection and sexual mixing patterns of drug-using male sex workers.

BACKGROUND: Drug-using male sex workers (DUMSWs) are known to have large numbers of drug injection and sex partners. GOALS: The purpose of this study was to describe the assortative and disassortative drug injection and sexual mixing patterns of DUMSWs. Implications of the high rates of disassortative mixing patterns of DUMSWs for HIV infection are discussed. Implications of disassortative mixing of DUMSWS with regard to DUMSWs bridging disparate HIV risk groups are evaluated. STUDY DESIGN: Data were collected from 89 DUMSWS. Data on up to six drug injection and six sex partners were collected from respondents. One hundred drug injection and 169 sex respondent/partner pairs were analyzed for the proportions of pairs that were concordant (like) or discordant (unlike) in gender, trading sex for money, race/ethnicity, and age cohort. For race/ethnicity and age, within-group differences were assessed with chi-square statistics. RESULTS: Data showed high proportions of discordant respondent/partner pairs for both drug injection and sex by gender, trading sex for money, race/ethnicity, and age. Significant within-group differences in rates of discordant pairs were found for both behaviors in relation to race/ethnicity and age. Minority persons and respondents 19 years of age or younger were more likely to be in discordant pairs. CONCLUSIONS: Direct assessment of HIV risk posed by the mixing patterns was not possible. Elaborating the mechanisms by which DUMSWs might act as an epidemiologic bridge is complex and involves more variables than were explored in this study. Nevertheless, such a study would be worthwhile.
