Risk factors for hepatitis C virus infection among patients receiving health care in a Department of Veterans Affairs hospital

A cross-sectional, seroepidemiological study was conducted to determine the prevalence and risk factors for hepatitis C virus (HCV) infection among veterans receiving health care from the VA. Among 274 evaluated outpatients, anti-HCV was found in 27 (9.9%). The prevalence of anti-HCV was 3.7% among 190 individuals who reported no illicit drug use compared to 24.7% among 81 subjects who had used drugs (P < 0.001). The prevalence of anti-HCV was 4.8% among 208 veterans who had never been incarcerated compared to 27.9% among 61 veterans who had been incarcerated (P < 0.001). A multivariate model found the following factors to be independently associated with anti-HCV: having used illicit drugs [odds ratio (OR) = 3.7, 95% CI 1.3–11.8; P = 0.001), having been incarcerated ( OR = 4.4, 95% CI 1.7–10.9; P = 0.001), and a yearly income less than US $10,000 ( OR = 3.5, 95% CI 1.3–9.4; P = 0.002). Because HCV infection was most strongly associated with illicit drug use, incarceration, and low income, these risk factors should be utilized to develop screening strategies among VA patients.     

Drug Use, Increasing Incarceration Rates, and Prison-Associated HIV Risks in Thailand

Background: Incarceration is a known risk for HIV infection in Thai drug users. Through the 1990s, incarceration rates for drug-related offenses rose sharply, whereas HIV prevention and drug treatment in prisons remained limited. Methods: We assessed HIV and incarceration risks for injection drug users (IDU) and non-IDU in a large treatment center cohort in northern Thailand to investigate HIV and prison risks in this period. We used Thai Bureau of Corrections data to assess incarceration and prevention funds in prisons, 1992–2000. Results: Among 1,865 drug user in the treatment cohort, 503 (27.0%) had ever been jailed. Men (OR 3.3, 95% CI 2.1, 5.2), IDU (OR 6.3, 95% CI 5.1, 7.9), and men who have sex with men (MSM) (OR 3.4, 95% CI 1.8, 6.3) were more likely to have been jailed. Among male IDU who had ever been jailed (N = 272), 15.8% had used drugs in prison. In a multivariate model, incarceration and ever IDU remained independently associated with HIV infection; IDU, MSM behaviors, and harmful traditional practices remained independently associated with having been jailed. From 1992 to 2000, overall alleged narcotics offenses increased from 117,000 to 276,000/year. The number of persons incarcerated for narcotics offenses increased fivefold from 1992 to 1999, from 12,860 to 67,440. For FY 2000, narcotics treatment accounted for 0.06% of the Thai corrections budget, whereas HIV programs in prisons were 0.017%. Conclusions: Incarceration rates for narcotics offenses have increased sharply in Thailand, whereas prevention has lagged. Having been jailed is an important independent risk for HIV infection among Thai male drug users, especially IDU and MSM. HIV prevention and drug treatment are urgently needed in Thai prisons.     

Prior opiate injection and incarceration history predict injection drug use among inmates

Aims To describe injection drug use among inmates, and to identify correlates of drug injection while incarcerated. Design Cross‐sectional survey. Setting Six provincial correctional centres in Ontario, Canada. Participants Face‐to‐face interviews were conducted with a random sample of 439 adult males and 158 females. Measurements Inmates were asked about drug use in their lifetime, outside the year prior to their current incarceration, and while incarcerated in the past year. Among the 32% (189 / 597) with a prior history of drug injection, independent correlates of injection while incarcerated in the past year were identified using multiple logistic regression. Findings Among all inmates while incarcerated in the past year, 45% (269 /597) used drugs and 19% (113 / 596) used non‐cannabis drugs. Among those with a prior history of injecting, 11% (20 / 189) injected while incarcerated in the past year. Rates of injection with used needles were the same pre‐incarceration as they were while incarcerated (32%). Independent correlates of drug injection while incarcerated were injection of heroin (OR = 6.4) or other opiates (OR = 7.9) and not injected with used needles (OR = 0.20) outside in the year prior to incarceration, and ever being incarcerated in a federal prison (OR = 5.3). Conclusions The possibility of transmission of human immunodeficiency virus (HIV), hepatitis C (HCV) or other blood‐borne diseases exists in Ontario correctional centres. In this setting, drug injection while incarcerated is primarily related to opiate use prior to incarceration. The correlation between injecting and extensive incarceration history suggests missed opportunities to improve inmates’ health.     

Substance Use Disorder Prevalence among Female State Prison Inmates

Background: Substance use disorders (SUDs) are prevalent among female inmates. As the female state prison population continues to increase, describing the specific clinical and demographic characteristics of female prisoners remains of paramount importance to better define women’s needs in the state prison system. Objectives: To determine the prevalence and patterns of current DSM-IV SUDs and explore whether particular demographic characteristics are more strongly associated with specific SUD categories. Methods: Data were derived from routine clinical assessments of 801 female inmates incarcerated in the Minnesota Department of Corrections state prison system. The Substance Use Disorder Diagnostic Schedule-IV (Hoffmann NG, Harrison PA. SUDDS-IV: Substance Use Disorder Diagnostic Schedule-IV. Smithfield, RI: Evince Clinical Assessments, 1995) was administered to all inmates as a computer-prompted interview on admission to the prison. Results: Of the inmates, 70.0% were dependent on at least one substance, and 7.9% met criteria for substance abuse. Alcohol dependence (30.2%) and cocaine dependence (30.1%) were the two most prevalent SUDs. The remaining substance dependence diagnoses that predominated were as follows: stimulant dependence, 24.1%; marijuana dependence, 15.6%; and heroin dependence, 9.6%. Over half (56.9%) were dependent on a substance other than alcohol. Prevalence of cocaine dependence [odds ratio (OR) = 2.83, 95% confidence interval (CI) = 1.92–4.16] was significantly higher among African Americans, whereas prevalence of stimulant dependence (OR = 9.24, 95% CI = 5.40–15.80) was significantly higher among Caucasians. Prevalence of alcohol (OR = 2.12, 95% CI = 1.38–3.25) and heroin (OR = 2.67, 95% CI = 1.50–4.77) dependence was significantly higher among Native Americans. Conclusions and Scientific Significance: SUDs in general, and illicit drug use disorders in particular, are prevalent among female inmates entering a state prison system. Membership to a particular ethnic group may identify a set of inmates at elevated risk for the presence of substance-specific dependence diagnoses.     

Substance Use and HIV-Risk Behaviors Among Young Men Involved in the Criminal Justice System

Objectives: We examined the relationship between substance use and sexual HIV-risk behaviors among young men who have been incarcerated, in order to understand how HIV risks develop for this vulnerable population. Methods: A sample of 552 young men in a New York City jail was interviewed at the time of incarceration. Bivariate analyses were performed to examine demographic and sexual HIV-risk behavior differences between men with and without recent alcohol and marijuana use. Logistic regression was used to examine associations between alcohol and marijuana use and sexual HIV-risk behaviors in the 90 days prior to incarceration. Results: Respondents were predominantly Black (57%) or Latino (37%), with a mean age of 17.4 years. The most common substances used were marijuana (82%) and alcohol (65%). Alcohol use prior to incarceration was significantly associated with having three or more sexual partners in the same time period (OR = 2.40, p < .001), as well as with having unprotected sex with a long-term partner (OR = 1.72, p < .01). Marijuana use was significantly associated with having multiple sex partners (OR = 1.55, p < .01). Heavy alcohol and marijuana use did not result in an increased likelihood of sexual HIV-risk behaviors. Conclusions: High rates of substance use and unprotected sex may have unintended health consequences for incarcerated young men. Severity of substance use is not a significant predictor of risk behaviors, suggesting the importance of contextual and social factors. Results highlight the need for HIV prevention efforts for this population that take into account contextual and social factors.     

HIV risk behaviour correlates among injecting drug users in Greek prisons

Aims. To identify the correlates of injecting drug use within prison. Design. A national cross-sectional study, participation being voluntary and anonymous. Setting. Ten Greek prisons. Participants. A representative sample of 1000 male inmates; 861 questionnaires were completed and analysed. Measurement. A self-report questionnaire for demographics, penal history, drug use and sharing injecting equipment. Findings. Two hundred and ninety inmates (33.7%) reported injecting drugs at some time in their lives, of whom 174 (60%) had injected while imprisoned. Among those who had injected while imprisoned, 145 (83%) had shared equipment while incarcerated. Logistic regression analysis suggested that total time in prison, previous drug conviction, being a convict (as opposed to on remand) and having multiple female sexual partners 1 year before incarceration were significant HIV risk behaviour correlates. For every year of imprisonment, the risk of injection in prison increased by about 17% \[OR = 1.17 (95% CI: 1.07-1.27)]. Inmates with a previous drug-related conviction were about twice as likely to inject within prison \[OR = 1.97 (95% CI: 1.16-3.33)]. Finally, convicted inmates were marginally significantly more prone to inject in prison \[OR = 1.58 (95% CI: 0.92-2.74)]. Conclusions. Variables related to the inmates' prison career influence HIV risk behaviours within prison. There is a need to assist IDUs in reducing the likelihood of high-risk behaviour by considering factors such as frequency of incarceration, length of time incarcerated and availability of detoxification programmes within prison.     

Univariable associations between a history of incarceration and HIV and HCV prevalence among people who inject drugs across 17 countries in Europe 2006 to 2020 – is the precautionary principle applicable?

BackgroundPeople who inject drugs (PWID) are frequently incarcerated, which is associated with multiple negative health outcomes.AimWe aimed to estimate the associations between a history of incarceration and prevalence of HIV and HCV infection among PWID in Europe.MethodsAggregate data from PWID recruited in drug services (excluding prison services) or elsewhere in the community were reported by 17 of 30 countries (16 per virus) collaborating in a European drug monitoring system (2006–2020; n = 52,368 HIV+/−; n = 47,268 HCV+/−). Country-specific odds ratios (OR) and prevalence ratios (PR) were calculated from country totals of HIV and HCV antibody status and self-reported life-time incarceration history, and pooled using meta-analyses. Country-specific and overall population attributable risk (PAR) were estimated using pooled PR.ResultsUnivariable HIV OR ranged between 0.73 and 6.37 (median: 2.1; pooled OR: 1.92; 95% CI: 1.52–2.42). Pooled PR was 1.66 (95% CI 1.38–1.98), giving a PAR of 25.8% (95% CI 16.7–34.0). Univariable anti-HCV OR ranged between 1.06 and 5.04 (median: 2.70; pooled OR: 2.51; 95% CI: 2.17–2.91). Pooled PR was 1.42 (95% CI: 1.28–1.58) and PAR 16.7% (95% CI: 11.8–21.7). Subgroup analyses showed differences in the OR for HCV by geographical region, with lower estimates in southern Europe.ConclusionIn univariable analysis, a history of incarceration was associated with positive HIV and HCV serostatus among PWID in Europe. Applying the precautionary principle would suggest finding alternatives to incarceration of PWID and strengthening health and social services in prison and after release (‘throughcare’).     

Characteristics associated with anti-HCV serological markers in prisoners in the state of Paraná, Brazil: a case-control study

BackgroundThe prison system in Paraná, Brazil, is experiencing serious problems related to the increasing number of prisoners. Control of hepatitis C virus (HCV) has become more intense because the incarcerated population is considered a high-risk group for contagious diseases due to the favorable conditions found in prisons for the spread of these morbidities. The objective of this study was to identify features associated with hepatitis C infection among male prisoners in correctional institutions of Paraná state, Brazil.MethodsThis was a case-control study (27 cases and 54 controls) of men incarcerated in 11 penitentiaries in Paraná, Brazil. Information was obtained through a questionnaire in a cross-sectional epidemiological survey on HCV infection during the period from May 2015 to December 2016. Eligible men were recruited after testing positive for anti-HCV antibodies. Cases and controls were selected based on serological results of enzyme-linked immunosorbent assays and were matched by age, location of the penitentiary, and time in prison. Logistic regression analysis was used to identify risk factors for HCV seropositivity.ResultsThe main significant independent risk factor for the acquisition of HCV infection was the use of injectable drugs (OR = 4.00; 95%CI:1.41–11.35; p < 0.001).ConclusionsThis study provides evidence that HCV infection is associated with drug use by this population. This information is pivotal for tailoring prevention programs and guiding specific socioeducational measures that aim to reduce or prevent HCV transmission within the prison setting.     

Factors Associated with Incarceration in Older Adults Experiencing Homelessness: Results from the HOPE HOME Study

BackgroundIn the US, the median age of adults experiencing homelessness and incarceration is increasing. Little is known about risk factors for incarceration among older adults experiencing homelessness. To develop targeted interventions, there is a need to understand their risk factors for incarceration.ObjectiveTo examine the prevalence and risk factors associated with incarceration in a cohort of older adults experiencing homelessness.DesignProspective, longitudinal cohort study with interviews every 6 months for a median of 5.8 years.ParticipantsWe recruited adults ≥50 years old and homeless at baseline (n=433) via population-based sampling.Main MeasuresOur dependent variable was incident incarceration, defined as one night in jail or prison per 6-month follow-up period after study enrollment. Independent variables included socioeconomic status, social, health, housing, and prior criminal justice involvement.Key ResultsParticipants had a median age of 58 years and were predominantly men (75%) and Black (80%). Seventy percent had at least one chronic medical condition, 12% reported heavy drinking, and 38% endorsed moderate-severe use of cocaine, 8% of amphetamines, and 7% of opioids. At baseline, 84% reported a lifetime history of jail stays; 37% reported prior prison stays. During follow-up, 23% spent time in jail or prison. In multivariable models, factors associated with a higher risk of incarceration included the following: having 6 or more confidants (HR=2.13, 95% CI=1.2–3.7, p=0.007), remaining homeless (HR=1.72, 95% CI=1.1–2.8, p=0.02), heavy drinking (HR=2.05, 95% CI=1.4–3.0, p<0.001), moderate-severe amphetamine use (HR=1.89, 95% CI=1.2–3.0, p=0.006), and being on probation (HR=3.61, 95% CI=2.4–5.4, p<0.001) or parole (HR=3.02, 95% CI=1.5–5.9, p=0.001).ConclusionsOlder adults experiencing homelessness have a high risk of incarceration. There is a need for targeted interventions addressing substance use, homelessness, and reforming parole and probation in order to abate the high ongoing risk of incarceration among older adults experiencing homelessness.KEY WORDS: incarceration, homelessness, vulnerable populations     

HIV Transmission Behaviors in Jail/Prison Among Puerto Rican Drug Injectors in New York and Puerto Rico

This study examined HIV risk behavior in jail/prison among Puerto Rican drug injectors in New York (NY, n = 300) and Puerto Rico (PR, n = 200), and its relationship with later drug and sex risk behaviors. During 3 years prior to interview, 66% of NY and 43% of PR samples were incarcerated at least once. While incarcerated, 5% of NY and 53% of PR injected drugs. Few reported engaging in sex inside jail/prison (5% in both sites). Of those who engaged in risk behaviors in jail/prison, almost all reported having unprotected sex and sharing injection equipment. The impact of jail/prison risk behaviors on risk behaviors after release differed between the two sites: they were more related to subsequent sex risk behaviors in NY, and subsequent injection risk behaviors in PR. The findings indicate a need for effective drug treatment programs inside jail/prisons to reduce HIV-related risk behaviors among drug injectors during incarceration and after release.     

Past year and prior incarceration and HIV transmission risk among HIV-positive men who have sex with men in the US*

Three quarters of new HIV infections in the US are among men who have sex with men (MSM). In other populations, incarceration is a social determinant of elevations in viral load and HIV-related substance use and sex risk behavior. There has been limited research on incarceration and these HIV transmission risk determinants in HIV-positive MSM. We used the Veterans Aging Cohort Study (VACS) 2011-2012 follow-up survey to measure associations between past year and prior (more than one year ago) incarceration and HIV viral load and substance use and sex risk behavior among HIV-positive MSM (N?=?532). Approximately 40% had ever been incarcerated, including 9% in the past year. In analyses adjusting for sociodemographic factors, past year and prior incarceration were strongly associated with detectable viral load (HIV-1 RNA >500 copies/mL) (past year adjusted odds ratio (AOR): 3.50 95% confidence interval (CI): 1.59, 7.71; prior AOR: 2.48 95% CI: 1.44, 4.29) and past 12 month injection drug use (AORs?>?6), multiple sex partnerships (AORs?>?1.8), and condomless sex in the context of substance use (AORs?>?3). Past year incarceration also was strongly associated with alcohol and non-injection drug use (AOR > 2.5). Less than one in five HIV-positive MSM recently released from incarceration took advantage of a jail/prison re-entry health care program available to veterans. We need to reach HIV-positive MSM leaving jails and prisons to improve linkage to care and clinical outcomes and reduce transmission risk upon release.     

Chapter 6: Incarcerated Latinas and Alcohol and Other Drug Abuse

SUMMARY

An increase in incarceration rates and incidence of drug-related incarcerations for women has shown particularly high rates for ethnic women. Profiles of incarcerated women in general show a number of factors that create psychosocial obstacles. Recent statistics indicate that Latino women are twice as likely to be in prison in comparison to white female prisoners. The literature on Latinas and alcoholism and other drug abuse is reviewed, clinical observations of incarcerated Latinas are discussed and recommendations are presented for service delivery needs.     

Illicit drug use and injection practices among drug users on methadone and buprenorphine maintenance treatment in France

Aims To evaluate the associations between methadone and high‐dose buprenorphine maintenance treatment and illicit drug use and injection among drug users in France. Design A cross‐sectional study. Data were gathered using a questionnaire administered containing closed‐ended questions. Setting Drug dependence clinics (DDC) and general practitioners’ (GPs) offices in three French cities. Participants Drug users undergoing maintenance treatment with methadone (n = 197) and buprenorphine (n = 142). Measurements Interviews covered the use of illicit drugs (heroin, cocaine or crack) and injection practices (illicit drugs and/or substitution drugs) during the last month, current treatment modalities, socio‐demographic and health characteristics. Bivariate analysis and multivariate logistic regressions were conducted. Findings Overall, 35.4% of respondents (34.5% in the methadone group, 36.6% in the buprenorphine group, P= 0.69) had used at least one illicit drug, 25.7% reported having injected drugs and 15.3% had injected the substitution drug. Injection was more common among buprenorphine‐maintained individuals (40.1%) than among users on methadone (15.2%) (P < 0.01). Multivariate analyses indicate that the type of substitution drug (buprenorphine versus methadone) was not associated with illicit drug use (OR = 1.1; 95% CI = 0.7–1.8). In the buprenorphine group, injection was related independently to social situation, as measured by housing (unstable versus stable housing, OR = 4.3; 95% CI = 1.6–11.5), but this was not the case in the methadone group. The risk of injection increased with buprenorphine dosage (high/low dosage OR = 6.2; 95% CI = 2.0–19.7), but this association was not observed in the methadone group. Conclusion Further studies comparing the benefits of these two types of treatment should be carried out, taking outcomes such as physical health, mental health and social functioning into consideration.     

Predictors of risky sex of young men after release from prison

A longitudinal study of demographic and behavioural characteristics associated with risky sexual behaviours of young men after release from prison. One hundred and six men were interviewed in prison and at one week and six months after release. Overall, 37% reported a previous sexually transmitted disease (STD) diagnosis. In the 30 days before incarceration, 33% had had sex with a risky partner, and 59% had had multiple female sex partners. After release, 38 (36%) men reported having had risky sex (>or=2 female sex partners and unprotected vaginal sex): 12 (13%) at one week and 31 (34%) at six months. The only factor independently associated with risky sex was the use of alcohol/drugs before sex: one-week odds ratio (OR)=6.11 (95% confidence interval [CI]: 1.42-26.40), six-month OR=3.05 (95% CI: 1.30-9.42). Behavioural intervention programmes for incarcerated men should address drug and alcohol use and its contribution to higher risk for HIV and STDs.     

Incarceration and drug use patterns among a cohort of injection drug users

Aims   Drug law enforcement remains the dominant response to drug-related harm. However, the impact of incarceration on deterring drug use remains under-evaluated. We sought to explore the relationship between incarceration and patterns of drug use among people who inject drugs (IDU).
Design   Using generalized estimating equations (GEE), we examined the prevalence and correlates of injection cessation among participants in the Vancouver Injection Drug User Study followed over 9 years. In subanalyses, we used McNemar's tests and linear growth curve analyses to assess changes in drug use patterns before and after a period of incarceration among participants reporting incarceration and those not incarcerated.
Findings   Among 1603 IDU, 842 (53%) reported injection cessation for at least 6 months at some point during follow-up. In multivariate GEE analyses, recent incarceration was associated negatively with injection cessation [adjusted odds ratio (AOR) = 0.43, 95% confidence interval (CI) 0.37–0.50], whereas the use of methadone was associated positively with cessation (AOR = 1.38, 95% CI 1.22–1.56). In subanalyses assessing longitudinal patterns of drug use among incarcerated individuals and those not incarcerated over the study period, linear growth curve analyses indicated that there were no statistically significant differences in patterns of drug use between the two groups (all P  > 0.05).
Conclusions   These observational data suggest that incarceration does not reduce drug use among IDU. Incarceration may inhibit access to mechanisms that promote injection cessation among IDU. In contrast, results indicate that methadone use is associated positively with injection cessation, independent of previous frequency of drug use.     

The impact of HIV disease on an Irish prison population.

Between January 1987 and January 1991, 168 known HIV-infected prisoners have been incarcerated in Dublin's Mountjoy prison. This figure constitutes 16.6% of the total HIV-infected population in the Republic of Ireland over the same period. One hundred and forty-one (84%) of these prisoners have attended the Department of Genitourinary Medicine, St James's Hospital, Dublin. This group displayed considerable morbidity from HIV-related disease. Respiratory tract infection was the most frequent complication seen. Much additional morbidity was directly attributable to intravenous drug use. A survey of a representative group of inmates revealed that 64.7% were diagnosed HIV-positive in prison. The mean length of time spent incarcerated since the diagnosis of HIV infection was 38.9 months. Twenty-nine of 34 individuals who answered a questionnaire were imprisoned for drug-related crimes and 32 of 34 prisoners admitted to parenteral drug use within the prison. As the HIV epidemic unfolds in Dublin, increasing numbers of prisoners with symptomatic HIV disease will spend time incarcerated in Mountjoy prison. This will pose a considerable burden on prison and hospital medical services alike.     

A survey of pre-arrest drug use in sentenced prisoners

The paper presents the results of a retrospective, self-report survey of pre-arrest drug use in a representative sample of 1751 men serving a prison sentence. Reported drugs used were cannabis (34%), opiates (9%), amphetamine (9%) and cocaine (5%), including 1%‘crack’ users. Pre-arrest injecting was reported by 11% of inmates, including 68% of all opiate users and 57% of amphetamine users. Drug dependence was reported by 11%, including 7% dependent on opiates, 2% on amphetamines and l% on cocaine. Relative to other drugs, the figure for cocaine is higher than is suggested by a previous clinic survey. Pre-arrest cannabis use was reported by 54% of black prisoners and 34% of white. White prisoners are more likely to report use of ‘hard’ drugs, drug dependence and injecting, but this masks a higher rate of cocaine use by black prisoners. Opiate use varied between health regions, from 3% of prisoners in the West Midlands to 25% of those from the Mersey region. These findings have implications for service provision and for an understanding of cultural influences on illicit drug use.     

HIV-infected men who have sex with men,before and after release from jail: the impact of age and race,results from a multi-site study

The US HIV/AIDS epidemic is concentrated among men who have sex with men (MSM). Black men are disproportionately affected by incarceration and Black MSM experience higher infection rates and worse HIV-related health outcomes compared to non-Black MSM. We compared HIV treatment outcomes for Black MSM to other HIV-infected men from one of the largest cohorts of HIV-infected jail detainees (N?=?1270) transitioning to the community. Of the 574 HIV-infected men released, 113 (19.7%) self-identified as being MSM. Compared to other male subgroups, young Black MSM (<30 years old, N?=?18) were significantly less likely: (1) before incarceration, to have insurance, access to an HIV healthcare provider, and use cocaine; (2) during incarceration, to receive a disease management intervention; and (3) in the 6 months post-release, to link to HIV care. Interventions that effectively link and retain young HIV-infected Black MSM in care in communities before incarceration and post-release from jail are urgently needed.     

Human immunodeficiency virus, hepatitis B and hepatitis C in an Indonesian prison: prevalence, risk factors and implications of HIV screening

Objective To determine the prevalence and behavioural correlates of HIV, HBV and HCV infections among Indonesian prisoners and to examine the impact of voluntary counselling and testing for all incoming prisoners on access to antiretroviral treatment (ART). Methods In a non‐anonymous survey in an Indonesian prison for drug‐related offences, all incoming prisoners and symptomatic resident prisoners were counselled and offered testing for HIV, hepatitis B and C. Results Screening was performed in 679 incoming prisoners, of whom 639 (94.1%) agreed to be tested, revealing a seroprevalence of 7.2% (95% CI 5.2–9.2) for HIV, 5.8% (95% CI 3.9–7.6) for HBsAg and 18.6% (95% CI 15.5–21.6) for HCV. Of 57 resident prisoners tested, 29.8% were HIV‐positive. HIV infection was strongly associated with injecting drug use (IDU; P < 0.001), but not with a history of unsafe sex. Screening of incoming prisoners was responsible for diagnosing and treating HIV in 73.0%, respectively, and 68.0% of HIV‐positive individuals. Conclusions HIV and HCV are highly prevalent among incoming Indonesian prisoners and almost entirely explained by IDU. Our study is the first to show that voluntary HIV counselling and testing during the intake process in prison may greatly improve access to ART in a developing country.     

Prevalence of and factors associated with HIV-1 infection among drug users visiting treatment centers in Tehran, Iran

OBJECTIVES: This study was conducted to identify the prevalence of and potential risk factors for HIV-1 infection among drug users visiting drug treatment centers in Tehran, Iran. DESIGN: Cross-sectional quantitative study. METHODS: Between October 2003 and May 2004, drug users who visited three public drug treatment centers in Tehran were interviewed and information about their sociodemographics, drug use characteristics, incarceration history, sexual history, and HIV/AIDS knowledge and risk perception were collected. Specimens of oral mucosal transudate were then collected from participants to be tested for HIV-1 antibodies. Logistic regression analysis was conducted on the association between the demographic and behavioral factors with HIV-1 infection. RESULTS: Overall, 611 (588 male and 23 female) drug users participated in the study. Among male injectors with HIV-1 prevalence of 15.2%, a history of shared injection inside prison [adjusted odds ratio (OR), 12.37; 95% confidence interval (CI), 2.94-51.97] was the main factor associated with HIV-1 infection. Among those who reported no history of injecting drug use, HIV-1 prevalence was 5.4%, and lack of condom use during sex was significantly associated with the infection (adjusted OR, 3.42; 95% CI, 1.25-9.36). CONCLUSIONS: HIV-1 infection is already prevalent among drug users in Tehran, Iran and shared injection inside prison has been revealed to be a particular risk factor for HIV-1 infection among injecting drug users. Harm reduction programs which have been started in Iran should be urgently expanded particularly in correctional settings and strengthened by condom use promotion to prevent sexual acquisition or transmission of HIV-1 among drug users.
