Contingency management reduces drug‐related human immunodeficiency virus risk behaviors in cocaine‐abusing methadone patients

Contingency management (CM) is efficacious in reducing drug use. This study examined whether CM also reduces human immunodeficiency virus (HIV) risk behaviors and if these effects are mediated by longest duration of abstinence achieved during treatment. Data were analyzed from a subset of participants in a combined data set of three published randomized controlled trials of CM treatments. A community-based methadone maintenance clinic. One-hundred and sixty-five cocaine-abusing methadone maintenance patients. Participants received either standard methadone treatment or standard methadone treatment with CM for 3 months. The HIV Risk Behavior Scale (HRBS) was administered prior to randomization to a study condition and 3 months after the study treatments ended. The primary objective indicator of drug use was longest duration of cocaine and opioid abstinence achieved during treatment. Relative to those assigned to standard care, participants receiving CM significantly decreased overall HIV risk behaviors and injection drug use risk behaviors. CM participants also achieved longer durations of consecutive cocaine and opioid abstinence during treatment. Duration of abstinence achieved mediated the relationship between treatment condition and HRBS difference scores. These results suggest that CM treatment reduces HIV drug use risk behaviors in cocaine-abusing methadone maintenance patients.

Characteristics and harms associated with injecting versus smoking methamphetamine among methamphetamine treatment entrants

To compare the characteristics and harms associated with injecting and smoking methamphetamine among methamphetamine treatment entrants. A structured face-to-face interview was used to assess demographics, drug use patterns and harms [physical and mental health, psychological distress, psychotic symptoms, crime and human immunodeficiency virus (HIV) risk behaviour] among 400 methamphetamine treatment entrants in Sydney and Brisbane, Australia. Participants who had injected but not smoked methamphetamine in the month before treatment (n = 195, injectors) were compared to participants who had either: (a) injected and smoked (n = 90, injectors who smoke), or (b) smoked but not injected (n = 73, smokers), during this time. In comparison with injectors, smokers were primarily non-injecting drug users, who were younger, more likely to be female and use ecstasy rather than heroin. After adjusting for these differences smokers were less dependent on methamphetamine than injectors, but they took the drug as often and had similarly high levels of psychological distress, poor physical and mental health, psychotic symptoms, sexual risk behaviour and criminal involvement. Injectors who smoked had a similar demographic and clinical profile to injectors, including comparable levels of needle sharing, but they used methamphetamine more often and had greater criminal involvement. Within this treatment sample, smoking methamphetamine occurred among both long-standing injecting drug users and a comparatively younger group of non-injecting drug users. It was associated with less severe methamphetamine dependence than injecting, but more intense use patterns and similar levels of other harms.

Methamphetamine dependence and human immunodeficiency virus risk behavior

We examined human immunodeficiency virus (HIV)-related risk behaviors among methamphetamine (MA)-dependent users. Secondary data analysis was performed on data from a large clinical trial: The Methamphetamine Treatment Project ( N = 784). All MA-dependent participants were enrolled in an outpatient treatment program, receiving either a standardized psychosocial protocol (Matrix model) or treatment-as-usual. HIV-related risk behavior, including injection and unsafe sexual practices, was assessed using the AIDS Risk Assessment at baseline, treatment discharge, and 6, 12, and 36 months following treatment participation. Results indicated that HIV risk behaviors substantially decreased over time. Treatment factors (retention and completion) and frequency of MA use were both positively associated with increased reduction of HIV risk behaviors. The findings suggested that treatment of MA dependence is promising for reducing behaviors that have been shown to transmit HIV.

Substance abuse treatment in human immunodeficiency virus: The role of patient–provider discussions

Substance abuse treatment is associated with decreases in human immunodeficiency virus (HIV) risk behavior and can improve HIV outcomes. The purpose of this study was to examine factors associated with substance abuse treatment utilization, including patient–provider discussions of substance use issues. We surveyed 951 HIV-infected adults receiving care at 14 HIV Research Network primary care sites regarding drug and alcohol use, substance abuse treatment, and provider discussions of substance use issues. Although 71% reported substance use, only 24% reported receiving substance abuse treatment and less than half reported discussing substance use issues with their HIV providers. In adjusted logistic regression models, receipt of substance abuse treatment was associated with patient–provider discussions. Patient–provider discussions of substance use issues were associated with current drug use, hazardous or binge drinking, and Black race or ethnicity, though substance use was comparable between Blacks and Whites. These data suggest potential opportunities for improving engagement in substance abuse treatment services.

Depression Symptoms and Sexual HIV Risk Behavior Among Serodiscordant Couples

To examine data for human immunodeficiency virus (HIV)-positive patients in serodiscordant relationships to determine a) if depressive symptoms were associated with sexual risk behavior and b) if these relationships could be explained by changes in partner satisfaction. The relationship between depression symptoms and sexual risk behaviors within mixed HIV status couples is unknown. HIV-positive and HIV-negative members of 197 serodiscordant couples (159 male/female, 38 male/male) were assessed using instruments measuring depressive symptoms, sexual risk, and couple satisfaction. HIV-positive partners with higher depression scores were less likely to be part of couples reporting unprotected sex, and HIV-positive partners' higher depression scores were associated with less unprotected intradyadic sex acts. This decrease in intradyadic sexual risk behavior was partially explained by a decrease in any sexual behavior within the couple. On the other hand, HIV-positive subjects with moderate or higher depression were more likely to have outside partners. Adding the partner satisfaction measure to the models was able to account for the relationship between the HIV-positive subjects' depression scores and outside partners, but not for that between higher depression score and reduced intradyadic sexual risk. HIV-positive individuals with more depressive symptoms may be less likely to engage in high-risk sexual behavior with their partners than those with less depressive symptoms, but more likely to have sexual partners outside the relationship. These findings suggest that the relationship between depressive symptoms and sexual risk behavior in this population may be mixed and complex, and suggest that clinicians should assess sexual risk behavior across the range of depression symptom severity.

Prevalence of Human Immunodeficiency Virus Infection, Risk Behavior, and HIV Knowledge Among Tuberculosis Patients in Afghanistan

To assess prevalence and correlates of human immunodeficiency virus (HIV) infection, risk factors, and HIV knowledge among tuberculosis patients in Afghanistan. Adult participants undergoing treatment for tuberculosis in this cross-sectional study completed a questionnaire and HIV testing between November 2005 and February 2006. Prevalence of HIV and high-risk behaviors were calculated, with correlates of high-risk behavior and relevant knowledge assessed. Of 1163 participants, 2 (0.2%, 95% CI: 0.0-0.6) were HIV-infected. Known risk factors for HIV infection, such as paying women for sex or male to male sexual contact, were rarely reported, though receipt of injections from a nonmedical provider was common (38%). Symptoms suspicious for sexually transmitted infection were reported by 5% of the population and were significantly associated with young (<26 years) age (OR: 3.2, 95% CI: 1.7-6.0). Relatively, a few participants had ever heard of HIV (23%) or condoms (25%). Condom use was significantly more frequent among those 26 and older (OR: 2.9, 95% CI: 1.7-5.2) and among male participants (OR: 1.5, 95% CI: 1.0-2.2). HIV prevalence among tuberculosis patients in Afghanistan is currently quite low. However, lack of knowledge of HIV and engaging in high-risk practices, particularly regarding health, make this group vulnerable. Health education sessions regarding HIV, sexually transmitted infection, and blood-borne infections should be implemented for tuberculosis patients during the treatment course.

The impact of an integrated treatment on HIV risk behavior among homeless youth: a randomized controlled trial

While many studies provide useful information on the risk behaviors in which homeless youth engage, few prior studies evaluate Human Immunodeficiency Virus (HIV) risk related reduction strategies. In this study, homeless youth (n = 180) were recruited from a drop-in center and randomly assigned to one of two conditions, either an integrated individual cognitive-behavioral treatment and HIV prevention intervention that focused on skills building and education or to treatment as usual. All youth were assessed at entry into the program and at 3 and 6 month follow-up points. Findings showed an interaction between treatment condition, age and time. In the interaction, youth assigned to the integrated treatment reported greater condom usage than youth assigned to treatment as usual, with younger youth assigned to treatment as usual showing no change in condom use. The number of sexual partners reported by youth in both treatment conditions was also reduced over time. However, youth in both conditions continued to engage in other high-risk behaviors. The integrated treatment findings are promising and suggest that interventions which target both HIV risk behavior in addition to other life areas (substance use, mental health and housing) among homeless youth may be necessary in order to significantly impact high-risk behaviors among this unique group.

Buprenorphine/naloxone treatment in primary care is associated with decreased human immunodeficiency virus risk behaviors

Methadone treatment reduces human immunodeficiency virus (HIV) risk, but the effects of primary-care-based buprenorphine/naloxone on HIV risk are unknown. The purpose of this study was to determine whether primary-care-based buprenorphine/naloxone was associated with decreased HIV risk behavior. We conducted a longitudinal analysis of 166 opioid-dependent persons (129 men and 37 women) receiving buprenorphine/naloxone treatment in a primary care clinic. We compared baseline and 12- and 24-week overall, drug-related, and sex-related HIV risk behaviors using the AIDS/HIV Risk Inventory (ARI). Buprenorphine/naloxone treatment was associated with significant reductions in overall and drug-related ARI scores from baseline to 12 and 24 weeks. Intravenous drug use in the past 3 months was endorsed by 37%, 12%, and 7% of patients at baseline and at 12 and 24 weeks, respectively ( p < .001). Sex while you or your partner were “high” was endorsed by 64%, 13%, and 15% of patients at baseline and at 12 and 24 weeks, respectively ( p < .001). Inconsistent condom use during sex with a steady partner was high at baseline and did not change over time. We conclude that primary-care-based buprenorphine/naloxone treatment is associated with decreased drug-related HIV risk, but additional efforts may be needed to address sex-related HIV risk when present (ClinicalTrials.gov number, NCT00023283).

Hepatitis C and human immunodeficiency virus risk behaviors in polydrug users on methadone maintenance

We examined the impact of methadone maintenance treatment (MMT) on risk behaviors for transmission of blood-borne diseases in polydrug users who had tested positive or negative for hepatitis C virus (HCV). At intake, HCV-positive participants ( n = 362) engaged in more human immunodeficiency virus (HIV) risk behaviors (as measured by the HIV Risk-Taking Behavior Scale) than HCV-negative participants ( n = 297; p < .001). This difference was specific to injection-related behaviors and decreased significantly within the first few weeks of MMT ( p < .0001). Where needles continued to be used, HCV-positive participants became more likely over time to engage in safer injecting practices. Furthermore, HCV-positive participants became more likely to use condoms than HCV-negative participants. These findings demonstrate that both drug- and sex-related risk behaviors decrease during MMT and emphasize the benefits of methadone programs for public health and HIV/HCV prevention.

Primary Medical Care and Reductions in HIV Risk Behaviors in Adults with Addictions

Human immunodeficiency virus (HIV) risk behaviors are prevalent in persons with addictions. Objectives: To assess whether exposure to primary medical care is associated with decreases in HIV risk behaviors. Design: Prospective 2-year cohort of 298 adults with addictions. Outcomes: Sex and drug-related HIV risk behaviors, measured by the Risk Assessment Battery. Predictors: Cumulative number of primary care visits (0, 1, p ⩽ 2). Associations were tested using regression models for correlated data. Results: In women, receipt of primary care was associated with less sex risk behavior (mean decrease 2.1, p ⩽0.1). Among women and men, ⩾2 primary care visits was associated with lower odds of any drug risk behavior (OR = 0.37, p = 0.03). Conclusions: Exposure to primary care can impact HIV risk behavior favorably among adults with addictions.

HIV risk behavior among injection drug users in Tehran, Iran

Iran faces parallel human immunodeficiency virus (HIV) and injection drug use epidemics; more than 62% of known HIV cases occur among injection drug users (IDU). We conducted a formative study of IDU in Tehran to explore risk behavior in the wake of the recent harm reduction efforts. Key informant interviews (n = 40), focus group discussions (nine groups of IDU, n = 66) and a review of existing published and unpublished literature were conducted. Participants included IDU, physicians, policy makers, police, IDU advocates and their families. IDU were diverse in gender, education, income and neighborhood of residence. Interviews were transcribed and analyzed using grounded theory. A typology of IDUs in Tehran, categorized according to self-defined networks as well as HIV risks, is presented. This categorization is based on the groups identified by IDUs, compared to those identified by other key informants, and on a secondary data review. Homeless, female, young IDU and users of a more potent form of heroin were identified as having increased risks for HIV. Participants described shortening transitions from smoked opium to injected opiates. Whereas a majority of participants considered needle sharing less common than previously, sharing continues in locations of group injection, and in states of withdrawal or severe addiction. System-wise barriers to harm reduction were discussed, and include the cost or stigma of purchasing needles from pharmacies, over-burdened clinics, irregular enforcement of laws protecting IDU and lack of efforts to address the sexual risks of IDU. This research is one of the first to describe a diversity of IDU, including women and higher socio-economic class individuals, in Tehran. While efforts in harm reduction in Iran to date have been notable, ongoing risks point to an urgent need for targeted, culturally acceptable interventions.

Trends in Hepatitis B Virus, Hepatitis C Virus, and Human Immunodeficiency Virus Prevalence, Risk Behaviors, and Preventive Measures among Seattle Injection Drug Users Aged 18–30 Years, 1994–2004

Injection drug users (IDUs) are at risk for infection with hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Information on time trends in prevalence of these viruses among IDUs and in behaviors influencing their transmission can help define the status of these epidemics and of public health efforts to control them. We conducted a secondary data analysis combining cross-sectional data from IDUs aged 18-30 years enrolled in four Seattle-area studies from 1994 to 2004. Participants in all four studies were tested for antibody to HIV (anti-HIV), hepatitis B core antigen (anti-HBc), and HCV (anti-HCV), and completed behavioral risk assessments. Logistic regression was used to investigate trends in prevalence over time after controlling for sociodemographic, drug use, and sexual behavior variables. Between 1994 and 2004, anti-HBc prevalence declined from 43 to 15% (p < 0.001), anti-HCV prevalence fell from 68 to 32% (p < 0.001) and anti-HIV prevalence remained constant at 2-3%. Declines in anti-HBc and anti-HCV prevalence were observed within the individual studies, although not all these declines were statistically significant. The declines in anti-HBc and anti-HCV prevalence remained significant after control for confounding. Although we did not observe coincident declines in injection equipment sharing practices, there were increases in self-reported needle-exchange use, condom use, and hepatitis B vaccination. We conclude that there has been a substantial and sustained reduction in prevalence rates for HBV and HCV infection among young Seattle IDUs, while HIV rates have remained low and stable.

Estimation of HIV Prevalence, Risk Factors, and Testing Frequency among Sexually Active Men Who Have Sex with Men, Aged 18–64 Years—New York City, 2002

Population-based estimates of human immunodeficiency virus (HIV) prevalence and risk behaviors among men who have sex with men (MSM) are valuable for HIV prevention planning but not widely available, especially at the local level. We combined two population-based data sources to estimate prevalence of diagnosed HIV infection, HIV-associated risk-behaviors, and HIV testing patterns among sexually active MSM in New York City (NYC). HIV/AIDS surveillance data were used to determine the number of living males reporting a history of sex with men who had been diagnosed in NYC with HIV infection through 2002 (23% of HIV-infected males did not have HIV transmission risk information available). Sexual behavior data from a cross-sectional telephone survey were used to estimate the number of sexually active MSM in NYC in 2002. Prevalence of diagnosed HIV infection was estimated using the ratio of HIV-infected MSM to sexually active MSM. The estimated base prevalence of diagnosed HIV infection was 8.4% overall (95% confidence interval [CI] = 7.5-9.6). Diagnosed HIV prevalence was highest among MSM who were non-Hispanic black (12.6%, 95% CI = 9.8-17.6), aged 35-44 (12.6%, 95% CI = 10.4-15.9), or 45-54 years (13.1%, 95% CI = 10.2-18.3), and residents of Manhattan (17.7%, 95% CI = 14.5-22.8). Overall, 37% (95% CI = 32-43%) of MSM reported using a condom at last sex, and 34% (95% CI = 28-39%) reported being tested for HIV in the past year. Estimates derived through sensitivity analyses (assigning a range of HIV-infected males with no reported risk information as MSM) yielded higher diagnosed HIV prevalence estimates (11.0-13.2%). Accounting for additional undiagnosed HIV-infected MSM yielded even higher prevalence estimates. The high prevalence of diagnosed HIV among sexually active MSM in NYC is likely due to a combination of high incidence over the course of the epidemic and prolonged survival in the era of highly active antiretroviral therapy. Despite high HIV prevalence in this population, condom use and HIV testing are low. Combining complementary population-based data sources can provide critical HIV-related information to guide prevention efforts. Individual counseling and education interventions should focus on increasing condom use and encouraging safer sex practices among all sexually active MSM, particularly those groups with low levels of condom use and multiple sex partners.

Human immunodeficiency virus (HIV) infection patterns and risk behaviours in different population groups and provinces in Viet Nam

To study patterns and determinants of HIV prevalence and risk-behaviour characteristics in different population groups in four border provinces of Viet Nam. We surveyed four population groups during April-June 2002. We used stratified random-cluster sampling and collected data concomitantly on HIV status and risk behaviours. The groups included were female sex workers (n = 2023), injecting drug users (n = 1391), unmarried males aged 15-24 years (n = 1885) and different categories of mobile groups (n = 1923). We found marked geographical contrasts in HIV prevalence, particularly among female sex workers (range 0-24%). The HIV prevalence among injecting drug users varied at high levels in all provinces (range 4-36%), whereas lower prevalences were found among both unmarried young men (range 0-1.3%) and mobile groups (range 0-2.5%). All groups reported sex with female sex workers. Less than 40% of the female sex workers had used condoms consistently. The strongest determinants of HIV infection among female sex workers were inconsistent condom use (adjusted odds ratio [OR], 5.3; 95% confidence interval [CI], 2.4-11.8), history of injecting drug use and mobility, and, among injecting drug users, sharing of injection equipment (adjusted OR, 7.3; 95% CI, 2.3-24.0) and sex with non-regular partners (adjusted OR 3.4; 95% CI 1.4-8.5). The finding of marked geographical variation in HIV prevalence underscores the value of understanding local contexts in the prevention of HIV infection. Although lacking support from data from all provinces, there would appear to be a potential for sex work to drive a self-sustaining heterosexual epidemic. That the close links to serious injecting drug use epidemics can have an accelerating effect in increasing the spread of HIV merits further study.

HIV Transmission Among Male Inmates in a State Prison System—Georgia, 1992-2005

The estimated prevalence of human immunodeficiency virus (HIV) infection is nearly five times higher for incarcerated populations (2.0%) than for the general U.S. population (0.43%). In 1988, the Georgia Department of Corrections (GDC) initiated mandatory HIV testing of inmates upon entry into prison and voluntary HIV testing of inmates on request or if clinically indicated. GDC offered voluntary HIV testing to inmates annually during July 2003-June 2005 and currently offers testing to inmates on request. During July 1988-February 2005, a total of 88 male inmates were known to have had both a negative HIV test result upon entry into prison and a subsequent confirmed positive HIV test result (i.e., seroconversion) during incarceration. Of these 88 inmates, 37 (42%) had had more than one negative HIV test result before their HIV diagnosis. In October 2004, GDC and the Georgia Division of Public Health invited CDC to assist with an epidemiologic investigation of HIV risk behaviors and transmission patterns among male inmates within GDC facilities and to make HIV prevention recommendations for the prison population. This report describes the results of that investigation, which identified the following characteristics as associated with HIV seroconversion in prison: male-male sex in prison, tattooing in prison, older age (i.e., age of >26 years at date of interview), having served > or =5 years of the current sentence, black race, and having a body mass index (BMI) of < or =25.4 kg/m2 on entry into prison. Findings from the investigation demonstrated that risk behaviors such as male-male sex and tattooing were associated with HIV transmission among inmates, highlighting the need for HIV prevention programs for this population.

Human Immunodeficiency Virus (HIV) and Substance Use Risk Behaviors among Tri-ethnic Adolescents of Florida

Previous research documents the co-occurrence of substance use and HIV risk behaviors, but most studies examined these behaviors among adults and White adolescents. The diversity of Florida's adolescents presents a unique setting for examining the variations in these risk behaviors. An in-depth analysis of HIV and substance use behaviors among White, African American, and Hispanic adolescents in Florida was conducted. Results suggest that significant ethnic variations exist in lifetime alcohol and illicit drug use and HIV risk. Compared with Hispanics, African Americans were less likely and Whites were more likely to be frequent alcohol and illicit drug users. White and African American adolescents were 1.3 and 1.5 times, respectively, at higher risk of at least one HIV risk behavior compared with their Hispanic counterparts. Future research should seek to identify sources and consequences of such variations in risk behavior and design culturally appropriate prevention programs for adolescents.

Mental health and sexual risk behaviours in a South African township: A community-based cross-sectional study

Despite the high prevalence of both mental illness and human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in developing countries, there are few data on the association between different forms of mental illness and sexual risk behaviours in resource-poor settings. The objective of this study was to examine the association between mental illness and HIV risk behaviours in a South African township. A cross-sectional study was performed among 645 individuals living in households selected at random. A self-administered translated questionnaire investigated sexual risk behaviours [including sexual partners, condom use, casual sexual contacts, and sex in exchange for money, drugs or a place to stay (transactional sex)], depression (measured using the Center for Epidemiological Studies Depression Scale), alcohol abuse (from the Alcohol Use Disorders Identification Test), and post-traumatic stress disorder (based on the Life Event Checklist). Of the 645 individuals who completed the survey, 33% reported depression, 17% reported alcohol abuse, and 15% reported post-traumatic stress disorder. After adjusting for demographic characteristics, the presence of any of these three conditions was strongly associated with experiences of forced sex [adjusted odds ratio (AOR) 2.53; 95% confidence intervals (CI) 1.60-4.02], transactional sex (AOR 2.88; 95% CI 1.29-6.48) and increased condom use (AOR 2.07; 95% CI 1.32-3.25). These findings emphasize the substantial burden of mental illness in this setting, and its association with forced and transactional sex. The temporal nature of these associations is not always clear from this cross-sectional study, and additional prospective research is required. Public health interventions are needed to address the dual burden of HIV/AIDS and mental illness in this and similar settings.

Knowledge and Risks of Human Immunodeficiency Virus Transmission among Veterans with Severe Mental Illness

This study is among the first to examine knowledge about human immunodeficiency virus (HIV) and behavioral risks for HIV transmission among veterans with severe mental illness (SMI), a group at high risk for HIV infection. This study examined associations between accuracy of HIV knowledge, risk behaviors, and clinical and demographic characteristics in a sample of male veteran psychiatric inpatients diagnosed with SMI (N = 353). Results showed high rates of inaccurate HIV knowledge, with > 40% of patients demonstrating some inaccuracies, particularly those related to the progression and symptoms of acquired immunodeficiency syndrome. Inaccurate HIV knowledge was associated with older age, minority status, education level, marital status, no homelessness within the previous 6 months, and no reported history of illicit intranasal drug use. There is a need for more effective HIV prevention interventions for persons with SMI.

Comparison of Pharmacological Treatments for Opioid-Dependent Adolescents

The prevalence of heroin and other opioid use has markedly increased among adolescents in the last decade; however, virtually no research has been conducted to identify effective treatments for this population. To evaluate the relative efficacy of 2 pharmacotherapies, the partial opioid agonist buprenorphine hydrochloride and the centrally active alpha(2)-adrenergic blocker clonidine hydrochloride, in the detoxification of opioid-dependent adolescents. A double-blind, double-dummy, parallel-groups randomized controlled trial conducted in a university-based research clinic from October 2001 to December 2003. Patients were a volunteer sample of 36 adolescents who met DSM-IV criteria for opioid dependence (ages 13-18 years eligible). Participants were randomly assigned to a 28-day, outpatient, medication-assisted withdrawal treatment with either buprenorphine or clonidine. Both medications were provided along with thrice weekly behavioral counseling and incentives contingent on opiate abstinence. Postdetoxification, all participants were offered the opportunity for continued treatment with the opiate antagonist, naltrexone hydrochloride. Treatment retention, opiate abstinence, and human immunodeficiency virus risk behavior, along with measures of withdrawal and medication effects. A significantly greater percentage of adolescents who received buprenorphine were retained in treatment (72%) relative to those who received clonidine (39%) (P<.05). For those in the buprenorphine group, a significantly higher percentage of scheduled urine test results were opiate negative (64% vs 32%; P = .01). Participants in both groups reported relief of withdrawal symptoms and drug-related human immunodeficiency virus risk behavior. Those in the buprenorphine condition generally reported more positive effects of the medication. No evidence of opioid intoxication or psychomotor impairment was observed. Sixty-one percent of participants in the buprenorphine condition and 5% of those in the clonidine group initiated treatment with naltrexone. Combining buprenorphine with behavioral interventions is significantly more efficacious in the treatment of opioid-dependent adolescents relative to combining clonidine and behavioral interventions.

HIV-Related Risk Factors Associated with Commercial Sex Among Female Migrants in China

Data from 633 sexually experienced female migrants were analyzed to examine the sociodemographic and psychosocial factors and human immunodeficiency virus (HIV)-related behaviors associated with involvement in commercial sex. Six percent (40/633) of the participants reported having had sex for money. Compared with women who had not engaged in commercial sex, women who had sold sex were younger, less educated, and more likely to be unmarried. They were more likely to have engaged in HIV-related risk behaviors, such as becoming intoxicated with alcohol and using drugs. Among women who engaged in commercial sex, only 28% of them consistently used condoms during the last three episodes of sexual intercourse. Women who had ever engaged in commercial sex demonstrated greater depressive symptoms than those without such a history (p < .01). Female migrants, especially those engaging in commercial sex, were vulnerable to HIV/sexually transmitted diseases (STDs). Sexual risk reduction and condom promotion are urgently needed among this population. Further studies are needed to examine the causal relationship between depression and HIV risk behaviors.
