Efficacy of a Woman-Focused Intervention to Reduce HIV Risk and Increase Self-Sufficiency Among African American Crack Abusers

Wendee M. Wechsberg; Wendy K. K. Lam; William A. Zule; Georgiy Bobashev

OBJECTIVES This study compares 3- and 6-month outcomes of a woman-focused HIV intervention for crack abusers, a revised National Institute on Drug Abuse standard intervention, and a control group. METHODS Out-of-drug-treatment African American women (n = 620) who use crack participated in a randomized field experiment. Risk behavior, employment, and housing status were assessed with linear and logistic regression. RESULTS All groups significantly reduced crack use and high-risk sex at each follow-up, but only woman-focused intervention participants consistently improved employment and housing status. Compared with control subjects at 6 months, woman-focused intervention participants were least likely to engage in unprotected sex; revised standard intervention women reported greatest reductions in crack use. CONCLUSIONS A woman-focused intervention can successfully reduce risk and facilitate employment and housing and may effectively reduce the frequency of unprotected sex in the longer term.

This study compares the characteristics of out-of-treatment, homeless, crack-using African-American women with those who are not homeless to determine what risks and protective factors differentiate the two groups. From 1999 to 2001, 683 out-of-treatment, African-American crack-using women (of whom 219 were categorized as homeless) were interviewed and serologically tested. Risk factors that were examined include adverse childhood experiences, psychological distress, physical health, violence and victimization, drug use, and risky sex behaviors. Protective factors that were examined include marital status, education, public assistance, and the responsibility of caring for children. Overall, both groups of women started crack use in their mid-twenties and started drug use with alcohol in their teenage years, though differed significantly on each risk factor examined. Logistic regression analysis found that variables associated with increased odds of being homeless are physical abuse before age 18, crack runs greater than 24 hours, income less than

500 in the last 30 days, depression, and current cigarette smoking. Protective factors found are marital status, living with children under 18, having had a physical in the past year, and receiving money from welfare in the last 30 days. Being sexually assaulted in the past 90 days was marginally associated with homelessness in the model. These findings, specific to crack-using African-American women, suggest that not only do these women overall report painful histories and currently stressful lives, but homeless women are more likely than women who are not homeless to have experienced childhood abuse and are more involved with drug use. Interventions designed for these women need to consider gender, cultural, and contextual issues that not only incorporate aspects of risk reduction related to violence, alcohol use, and comorbid conditions, but also linkages that will address housing issues, education, and skills for independence.

Risk and reciprocity : HIV and the injection drug user

William A. Zule

Drug injection and other practices affecting the risk of human immunodeficiency virus (HIV) infection were studied among 154 heroin users and 45 methamphetamine users in San Antonio, Texas. Amphetamine users were younger, mostly white, and had less-severe drug dependence. Heroin users had significantly higher levels of needle risk, as indicated by frequency of injection, number of persons sharing equipment, and place of injection. Methamphetamine users tended to buy syringes in lots of 10 or more from pharmacies and to use a syringe less than 5 times before discarding it. Heroin users tended to buy 1 needle at a time from an illicit source and to use it more than 20 times. Of methamphetamine users, 71% had more than one sex partner, compared to 39% of heroin users. Partners of methamphetamine users were more likely to be drug injectors than were partners of heroin users. Fewer methamphetamine users reported a behavior change in response to the acquired immunodeficiency syndrome (AIDS) epidemic, and fewer had been contacted by AIDS Education/Outreach. We suggest that efforts to promote risk reduction among methamphetamine users be stepped up because this population has been underserved and because less-sweeping behavior changes are needed to reduce needle-related risks to acceptable levels.

Injecting practices of illicit drug users in San Antonio, Texas, were studied by means of informal field interviews and participant observation. The methods injection drug users (IDUs) employed to obtain drugs seemed to affect their HIV risk behaviors. Many of the methods involve reciprocal exchanges between a person who has drugs and a person who wants drugs. The exchanges frequently occur in the context of asymmetrical social interactions. The person with the drugs usually occupies the dominant role in the interaction and determines the needle hygiene for both parties. Analysis of the decision-making process of IDUs indicates that the party in the dominant role may choose not to disinfect a syringe for a variety of reasons. An understanding of the subcultural rules that govern these interactions may provide valuable clues to researchers or educators who are designing interventions aimed at reducing HIV risk behaviors among IDUs. This research suggests that for IDUs in subordinate roles, education alone may be insufficient to produce behavior changes necessary to eliminate risk of HIV infection.

Behaviorally Bisexual Men and their Risk Behaviors with Men and Women

William A. Zule; Georgiy Bobashev; Wendee M. Wechsberg; Elizabeth C. Costenbader; Curtis M. Coomes

BackgroundWith HIV prevalence estimated at 20% among female injecting drug users (IDUs) in St. Petersburg, Russia, there is a critical need to address the HIV risks of this at-risk population. This study characterized HIV risks associated with injecting drug use and sex behaviors and assessed the initial feasibility and efficacy of an adapted Woman-Focused intervention, the Womens CoOp, relative to a Nutrition control to reduce HIV risk behaviors among female IDUs in an inpatient detoxification drug treatment setting.MethodWomen (N = 100) were randomized into one of two one-hour long intervention conditions--the Woman-Focused intervention (n = 51) or a time and attention-matched Nutrition control condition (n = 49).ResultsThe results showed that 57% of the participants had been told that they were HIV-positive. At 3-month follow-up, both groups showed reduced levels of injecting frequency. However, participants in the Woman-Focused intervention reported, on average, a lower frequency of partner impairment at last sex act and a lower average number of unprotected vaginal sex acts with their main sex partner than the Nutrition condition.ConclusionThe findings suggest that improvements in sexual risk reduction are possible for these at-risk women and that more comprehensive treatment is needed to address HIV and drug risks in this vulnerable population.

Methamphetamine use and risky sexual behaviors during heterosexual encounters.

William A. Zule; Elizabeth C. Costenbader; William Meyer; Wendee M. Wechsberg

Gay and bisexual men are often treated as a homogenous group; however, there may be important differences between them. In addition, behaviorally bisexual men are a potential source of HIV infection for heterosexual women. In this study, we compared 97 men who have sex with men only (MSM) to 175 men who have sex with men and women (MSMW). We also compared the 175 MSMW to 772 men who have sex with women only (MSW). Bivariate and multiple logistic regression analyses were performed to assess correlates of MSMW risk behaviors with men and with women as well as whether MSMW, compared with MSW, engaged in more risky behaviors with women. Compared with MSM, MSMW were less likely to be HIV-positive or to engage in unprotected receptive anal intercourse. In contrast, MSMW were more likely than MSW to be HIV-positive and to engage in anal intercourse with their female partners; however, rates of unprotected anal intercourse were similar. The study findings suggest that there may be important differences in HIV risk behaviors and HIV prevalence between MSM and MSMW as well as between MSMW and MSW.

Objective: This study examined the association between event-level methamphetamine use and heterosexual risk behaviors. Method: Data on 1213 heterosexual encounters were collected using audio-computer assisted self interviews from 703 injecting drug users in North Carolina. Data were obtained by asking participants a series of questions about the last time that they had sex (oral, vaginal, and/or anal). Although participants were interviewed at up to 3 time points, data were analyzed at the event level rather than as longitudinal because we were interested in the co-occurrence of methamphetamine use and sexual risk behaviors. Multivariate generalized estimating equations models were developed to examine the association between co-occurring methamphetamine use and each of 6 heterosexual risk behaviors. Results: Methamphetamine was used in 7% of encounters. Methamphetamine use by either or both partners was associated with an increased likelihood of anal intercourse (odds ratio [OR] = 2.41, 95% confidence interval [CI] = 1.29–4.53), vaginal and anal intercourse (OR = 2.41, 95% CI = 1.22–4.77), and sex with a new partner (OR = 1.98, 95% CI = 1.09–3.61). In addition to these behaviors, methamphetamine use by both partners was also significantly associated with unprotected intercourse with a new partner (OR = 5.20, 95% CI = 2.09–12.93) and unprotected anal intercourse (OR = 4.63, 95% CI = 1.69–12.70). Conclusions: Methamphetamine use during heterosexual encounters appears to increase sexual risk-taking, especially when both partners are using it.

Psychological distress in childhood trauma survivors who abuse drugs

Martha A. Medrano; John P. Hatch; William A. Zule; David P. Desmond

Transactional sex refers to selling sex (exchanging sex for money, drugs, food, shelter, or other items) or purchasing sex (exchanging money, drugs, food, shelter, or other items for sex). These activities have been associated with a higher risk for HIV and other sexually transmitted infections in a variety of populations and settings. This paper examines correlates of purchasing and selling sex in a large sample of drug users, men who have sex with men, and sex partners of these groups. Using respondent-driven sampling, participants were recruited between 2005 and 2008 in two urban and two rural counties in North Carolina. We used multiple logistic regressions to examine separate models for selling and purchasing sex in men and women. In addition, we estimated direct and indirect associations among independent variables in the logistic regression models and transactional sex using structural equation models. The analysis shows that factors associated with women selling and buying sex include being homeless, use of stimulants, bisexual behavior, and neighborhood disorder. There was also a significant difference by race. For men, the factors associated with selling and buying sex include being homeless, bisexual behavior, and not being in a relationship. Although neighborhood violence and disorder show significance in bivariate associations with the outcome, these associations disappear in the structural equation models.

Contextual factors and other correlates of sexual risk of HIV among African–American crack-abusing women

Amelia C. Roberts; Wendee M. Wechsberg; William A. Zule; Angela R Burroughs

The relationships between the level of childhood maltreatment and current psychological distress were examined in a community sample of 676 substance abusing men and women using a validated self-report instrument (the Childhood Trauma Questionnaire) designed to measure physical, emotional, and sexual abuse and physical and emotional neglect. Current levels of self-reported psychological distress/symptoms were measured using a 53-item Brief Symptom Inventory. Prevalence of early trauma ranged from 44% for emotional neglect to 65% for sexual abuse. The severity of all forms of childhood maltreatment were directly associated with current psychological distress.
