The gendered context of initiation to injecting drug use: evidence for women as active initiates

The gendered violence of injecting-related stigma among relatively affluent, suburban women who inject drugs

INTRODUCTION

In honouring the legacy of Jude Byrne's life-long advocacy for women and mothers who use drugs, this paper presents a case study of a group of women about whom we know little about and hear even less from: women who inject drugs in relatively affluent suburbs.

METHODS

Based on a 2020 qualitative study of people who inject drugs in an affluent area of Sydney known as 'The Beaches', we use in-depth interview data to thematically explore the lived experiences of gendered stigma among women who inject drugs.

RESULTS

Even when women occupy the 'ideal' social position in terms of class (middle-class) and race (White) they remain subject to harmful forms of gendered stigma related to injecting drug use. Participants had internalised negative attitudes around injection drug use as a form of failed femininity and, despite being part of 'good' families and neighbourhoods, participants experienced forced child removal.

DISCUSSION AND CONCLUSIONS

Taking the lead from feminist intersectionality scholarship, our data illustrate how stigma and discrimination act as a form of structural violence against women who inject drugs in affluent communities. While the social relations of gender provide some degree of protection by 'performing proximity to Whiteness', gendered stigma and violence persist.

Gender, sexual orientation identity, and initiation of amphetamine injecting among people who inject drugs: Examination of an expanding drug era in Montreal, Canada, 2011-19

BACKGROUND

Amphetamine injection is expanding in North America and has been associated with male homosexuality among people who inject drugs (PWID). Applying subcultural evolution theory, we examined overall and gender-stratified trends in amphetamine injection and assessed sexual orientation as a gender-specific predictor of initiation among PWID in Montreal, Canada.

METHODS

Data were from HEPCO, an open prospective cohort of PWID. Gender and sexual orientation were self-identified at enrolment. Interviewer-administered questionnaires at three-monthly (HCV RNA-negative participants) or yearly (RNA-positive) intervals captured past three-month amphetamine injection and covariates. Annual prevalence and linear trends in amphetamine injection were estimated using GEE. Incidence was computed among naïve individuals and hazard ratios for initiation estimated using gender-stratified, time-varying Cox regression models.

RESULTS

803 participants contributed 8096 observations between March 2011 and December 2019. Annual prevalence of amphetamine injecting increased from 3.25% [95%CI: 2.06-4.43%] to 12.7% [9.50-16.0] (trend p<0.001). Bivariate Cox regression models suggested similar and divergent predictors of initiation by gender. Incidence was 3.27 per 100 person-years [95%CI: 2.51-4.18] among heterosexual men, 7.18 [3.50-13.2] among gay/bisexual men, 1.93 [0.78-4.02] among heterosexual women and 5.30 [1.69-12.8] among gay/bisexual women. Among men, gay/bisexual identity doubled risk of initiation after adjusting for age, ethnicity, calendar year (aHR 2.16 [1.07-4.36]) and additional covariates (2.56 [1.24-5.30]). Among women, evidence for an association with gay/bisexual identity was inconclusive (aHR 2.63 [0.62-11.2]) and sample size precluded further adjustment CONCLUSIONS: Prevalence of amphetamine injection among PWID increased four-fold from 2011 to 2019, with elevated risk of initiation in gay and bisexual men.

First-line opioid agonist treatment as prevention against assisting others in initiating injection drug use: A longitudinal cohort study of people who inject drugs in Vancouver, Canada

Background

Among people who inject drugs, frequent injecting and experiencing withdrawal are associated with facilitating others' first injections. As these factors may reflect an underlying substance use disorder, we investigated whether first-line oral opioid agonist treatment (OAT; methadone or buprenorphine/naloxone) reduces the likelihood that people who inject drugs help others initiate injecting.

Methods

We used questionnaire data from semi-annual visits between December 2014-May 2018 on 334 people who inject drugs with frequent non-medical opioid use in Vancouver, Canada. We estimated the effect of current first-line OAT on subsequent injection initiation assistance provision (i.e., helped someone initiate injecting in the following six months) using inverse-probability-weighted estimation of repeated measures marginal structural models to reduce confounding and informative censoring by time-fixed and time-varying covariates.

Results

By follow-up visit, 54-64% of participants reported current first-line OAT whereas 3.4-6.9% provided subsequent injection initiation assistance. Per the primary weighted estimate (n = 1114 person-visits), participants currently on first-line OAT (versus no OAT) were 50% less likely, on average, to subsequently help someone initiate injecting (relative risk [RR]=0.50, 95% CI=0.23-1.11). First-line OAT was associated with reduced risk of subsequent injection initiation assistance provision in participants who, at baseline, injected opioids less than daily (RR=0.15, 95% CI=0.05-0.44) but not in those who injected opioids daily (RR=0.86, 95% CI=0.35-2.11).

Conclusions

First-line OAT seemingly reduces the short-term likelihood that people who inject drugs facilitate first injections. However, the extent of this potential effect remains uncertain due to imprecise estimation and observed heterogeneity by baseline opioid injecting frequency.

Investigating a bidirectional relationship between overdose and provision of injection initiation assistance among persons who inject drugs in Vancouver, Canada and Tijuana, Mexico

BACKGROUND

Individuals who initiate injection drug use often receive assistance from an injection-knowledgeable peer. Persons who assist peers in injection initiation events often inject frequently, which heightens overdose risk. As such, overdose and injection initiation events may be correlated. To explore a potential relationship, we assessed temporal associations between experiencing a non-fatal overdose and assisting others in initiating injection drug use among persons who inject drugs in two North American cities - Vancouver, Canada and Tijuana, Mexico.

METHODS

From 2014 to 2018, this retrospective cohort study included people who inject drugs from Vancouver (n=1332) and Tijuana (n=666) who completed a baseline and six-month follow-up interview. Within each site, we assessed bidirectional temporal associations using two separate multivariable logistic regression models: for model 1, recent provision of injection initiation assistance (at six months) was the outcome and recent overdose (at baseline) was the exposure; for model 2, recent overdose (at six months) was the outcome and recent provision of injection initiation assistance (at baseline) was the exposure. Both models adjusted for potential confounders.

RESULTS

Vancouver-based participants reporting overdose at baseline had 163% greater odds of reporting provision of injection initiation assistance at follow-up (adjusted Odds Ratio [aOR] 2.63; 95% Confidence Interval [CI] 1.41-4.90); while participants reporting provision of injection initiation assistance at baseline had 89% greater odds of reporting a non-fatal overdose at follow-up (aOR 1.89; 95% CI 1.00-3.57). Among Tijuana-based participants, we did not observe a statistically significant association in either direction.

CONCLUSION

Findings in Vancouver suggest that injection initiation assistance and overdose are bidirectionally-associated phenomena. The present findings highlight the need for interventions that ensure that persons who provide injection initiation assistance are given overdose prevention support, both for themselves and for those they assist to initiate injection drug use. While our Tijuana-based results did not suggest a bidirectional relationship, preventative approaches should nonetheless be undertaken.

Assisted injection provider practices and motivations in Los Angeles and San Francisco California 2016-18

BACKGROUND

Assisted injection is a high-risk and common practice among people who inject drugs (PWID) and occurs for diverse reasons according to qualitative research. To develop interventions for reducing assisted injection risks, it is important to understand the practices of PWID who provide injection assistance, including their motivations for providing assistance.

METHODS

Using follow-up data from an efficacy trial among PWID recruited in Los Angeles and San Francisco, CA (n=601), we present descriptive statistics on motivations for providing injection assistance and use multivariable logistic regression modelling to examine factors associated with these motivations.

RESULTS

PWID provided injection assistance most commonly to friends and acquaintances. A quarter provided assistance on a daily basis. The most common motivations for providing assistance were skill and injury prevention. PWID also provided assistance to stop pestering and for compensation in money or drugs. In separate models examining factors associated with the five main motivations, we found injury prevention to be associated with skill injecting others, neck injection, methamphetamine use, and recycling income. Pestering was associated with injury prevention, neck and hand injection, speedball use, and syringe selling. Skill was associated with injury prevention, neck and hand injection, being physically assaulted, and age. Providing assistance for money was associated with providing assistance for food or drugs, armpit injections, being female, and providing assistance more frequently. Providing assistance for drugs was associated with compensation in food or money, goofball injection, selling drugs, and panhandling.

CONCLUSION

Providing injection assistance is associated with injection needs of recipients and drug scene participation. We urgently need new interventions for reducing assisted injection risks. Since injection providers report being motivated by skill and to prevent injury, interventions such as training in safer injection techniques are likely to be met with enthusiasm.

Drug Injection-Related and Sexual Behavior Changes in Drug Injecting Networks after the Transmission Reduction Intervention Project (TRIP): A Social Network-Based Study in Athens, Greece

The Transmission Reduction Intervention Project (TRIP) was a network-based, enhanced contact tracing approach, targeting recently HIV-infected people who inject drugs (PWID) in Athens, Greece (2013–2015). This analysis examines behavioral changes of participants in TRIP and their determinants between baseline and follow-up visits to the program. All participants of TRIP were tested for HIV and interviewed using a questionnaire with items on drug injection-related and sexual behaviors. Multivariable logistic regression models were used to examine potential relationships between participants’ behaviors and sociodemographic or other characteristics. The analysis included 292 participants. At follow-up, the percentage of participants who injected drugs decreased [92.5%, n = 270 versus 72.3%, n = 211 (p < 0.001)], and more participants adopted safer behaviors. Employment, age, and gender were significantly associated with some behavioral changes. For instance, unemployed participants were half as likely as the employed to stop drug injection [adjusted odds ratio (aOR): 0.475, 95% confidence interval (CI): 0.228, 0.988]. Increasing age was associated with lower probability of sharing syringes at follow-up (aOR: 0.936, 95%CI: 0.887, 0.988). Finally, females were less likely than males to improve their behavior related to sharing cookers, filters, or rinse water (aOR: 0.273, 95% CI: 0.100, 0.745). In conclusion, adoption of safer behaviors was observed following TRIP implementation. Future prevention programs should focus on younger PWID and especially females. Social efforts to support employment of PWID are also important.

Factors associated with phylogenetic clustering of hepatitis C among people who inject drugs in Baltimore

Background

The availability of effective, oral direct acting antivirals (DAAs) for hepatitis C virus (HCV) treatment has put elimination of HCV as a public health challenge within reach. However, little is known about the characteristics of transmission networks of people who inject drugs (PWID).

Methods

Sequencing of a segment of the HCV genome was performed on samples collected from a community-based cohort of PWID between August 2005 and December 2016. Phylogenetic trees were inferred, and clusters were identified (70% bootstrap threshold; 0.04 maximum genetic distance threshold). We describe sex, race, age difference, and HIV infection status of potential transmission partners. Logistic regression was used to assess factors associated with being in an HCV cluster.

Results

Of 508 HCV genotype 1 viremic PWID, 8% (n = 41) were grouped into 20 clusters, consisting of 19 pairs and 1 triad. In adjusted analyses, female sex (odds ratio [OR] 2.3 [95% confidence interval (CI) 1.2–4.5]) and HIV infection (OR 5.7 [CI 2.7–11.9]) remained independently associated with being in an HCV infection cluster.

Conclusions

Molecular epidemiological analysis reveals that, in this cohort of PWID in Baltimore, HIV infection and female sex were associated with HCV clustering. Combination HCV prevention interventions targeting HIV infected PWID and addressing HCV infection prevention needs of women have potential to advance HCV elimination efforts.

Prevalence and Correlates of Providing and Receiving Assistance With the Transition to Injection Drug Use

Preventing the transition to injection drug use is an important public health goal, as people who inject drugs (PWID) are at high risk for overdose and acquisition of infectious disease. Initiation into drug injection is primarily a social process, often involving PWID assistance. A better understanding of the epidemiology of this phenomenon would inform interventions to prevent injection initiation and to enhance safety when assistance is provided. We conducted a systematic review of the literature to 1) characterize the prevalence of receiving (among injection-naive persons) and providing (among PWID) help or guidance with the first drug injection and 2) identify correlates associated with these behaviors. Correlates were organized as substance use behaviors, health outcomes (e.g., human immunodeficiency virus infection), or factors describing an individual's social, economic, policy, or physical environment, defined by means of Rhodes' risk environments framework. After screening of 1,164 abstracts, 57 studies were included. The prevalence of receiving assistance with injection initiation (help or guidance at the first injection) ranged 74% to 100% (n = 13 estimates). The prevalence of ever providing assistance with injection initiation varied widely (range, 13%-69%; n = 13 estimates). Injecting norms, sex/gender, and other correlates classified within Rhodes' social risk environment were commonly associated with providing and receiving assistance. Nearly all PWID receive guidance about injecting for the first time, whereas fewer PWID report providing assistance. Substantial clinical and statistical heterogeneity between studies precluded meta-analysis, and thus local-level estimates may be necessary to guide the implementation of future psychosocial and sociostructural interventions. Further, estimates of providing assistance may be downwardly biased because of social desirability factors.

Are non-injecting opioid users at risk of transition to injecting drug use? A multi-site study from India

BACKGROUND

Most people who inject drugs (PWID) start their drug use careers by using non-injecting opioid drugs. A variety of interconnected factors may influence the risk of transition from non-injecting to injecting drug use (IDU). However, such factors have not been studied well in India. As almost all non-injecting opioid users (NIOU) are at potential risk of switching to IDU in future, it is important to understand the phenomenon of transition.

METHOD

In this multi-site, cross-sectional observational study, we compared injecting and non-injecting opioid users on the pattern of progression of drug use and their knowledge, attitude and belief about IDU/HIV. Data were collected from people who use drugs coming in contact with Non-Governmental Organizations providing drug treatment or HIV prevention services, in ten cities of six states located in North/North-West India. Following informed consent, a total of 1987 male participants (n = 1234 PWID and n = 753 NIOU) were interviewed using a semi-structured questionnaire. Factors associated with risk of transition were analyzed using logistic regression analysis.

RESULT

The age of onset of heroin and other opiates as well as other substances was not different between two groups. Among PWID, a majority (n = 713; 57.77%) reported using opioids through non-injecting route before switching to injecting route. The mean duration between first use of non-injecting opioid and first use of injecting opioid was 1.80 ± 3.32 years (range 0-26 years). Awareness and exposure to the act of injecting were amongst factors associated with perceived risk of transition to injecting (p < 0.01). On a univariate logistic regression analysis, less education was associated with increased likelihood while being employed was associated with less likelihood of being offered injection (p < 0.001).

CONCLUSION

Though, NIOU are almost indistinguishable from PWID in many respects, there may be certain factors putting them at risk of transition to injecting route. As the majority of PWID start their injecting career by non-injecting route, interventions targeted atrisk NIOU (as suggested by our study) could interrupt the HIV transmission.

"Another Person Was Going to Do It": The Provision of Injection Drug Use Initiation Assistance in a High-Risk U.S.-Mexico Border Region

Background: Persons who inject drugs (PWID) play a key role in assisting others' initiation into injection drug use (IDU). We aimed to explore the pathways and socio-structural contexts for this phenomenon in Tijuana, Mexico, a border setting marked by a large PWID population with limited access to health and social services. Methods: Preventing Injecting by Modifying Existing Responses (PRIMER) is a multi-cohort study assessing socio-structural factors associated with PWID assisting others into initiating IDU. Semi-structured qualitative interviews in Tijuana included participants ≥18 years old, who reported IDU within the month prior to cohort enrollment and ever initiating others into IDU. Purposive sampling ensured a range of drug use experiences and behaviors related to injection initiation assistance. Thematic analysis was used to develop recurring and significant data categories. Results: Twenty-one participants were interviewed (8 women, 13 men). Broadly, participants considered public injection to increase curiosity about IDU. Many considered transitioning into IDU as inevitable. Emergent themes included providing assistance to mitigate overdose risk and to protect initiates from being taken advantage of by others. Participants described reluctance in engaging in this process. For some, access to resources (e.g., shared drugs or a monetary fee) was a motivator to initiate others. Conclusion: In Tijuana, public injection and a lack of harm reduction services are perceived to fuel the incidence of IDU initiation and to incentivize PWID to assist in injection initiation. IDU prevention efforts should address structural factors driving PWID participation in IDU initiation while including PWID in their development and implementation.

A qualitative study of persons who inject drugs but who have never helped others with first injections: how their views on helping contrast with the views of persons who have helped with first injections, and implications for interventions

BACKGROUND

Transitioning from non-injection to injection drug use dramatically escalates health risks. Evidence suggests that people who inject drugs (PWID) help in a majority of others' first injections, yet these helpers represent only a minority of experienced PWID. Recent research has provided insight into this helping process, as reported by helpers. PWID who have never helped, although the majority of PWID, have not previously been the focus of study. To address this gap, we give primary voice to non-helpers' perspectives on the helping process, while also comparing their views with persons in our sample who have helped with first injections. Finally, we consider how non-helpers' perspectives can inform harm reduction interventions to reduce, or make safer, initiation into injecting drug use.

METHODS

We conducted audio-recorded, qualitative interviews with 23 current opioid injectors on Staten Island, NY, where the opioid epidemic is pronounced. Seventeen had never helped with first injections and 6 had. Interviews were transcribed verbatim, and three coders used a consensus-developed codebook to code all interviews. Framework analysis was used to identify overarching themes.

RESULTS

We identified three key themes in non-helpers' discourse around not helping: altruistic motivations to prevent immediate and delayed harms to individuals injecting for the first time; inhibition due to negative assessments of their own injecting skills; and absolutist ethical convictions against helping. Non-helpers differed from helpers on each theme.

CONCLUSIONS

Because most PWID have never helped with first injections, their perspectives on helping warrant consideration and can inform harm reduction interventions to reduce, or make safer, transitions to injection drug use. Their perspectives can be used to broaden the factors PWID consider around questions of promoting injection and helping with others' first injections, including considerations of the moral issues involved in choosing to help or not to help.

Factors associated with time between using a drug and injection initiation among people who inject drugs in Kermanshah, Iran

Background The transition from non-injection to injection drug use dramatically increases the risk of transmitting HIV and other blood borne infections including hepatitis B virus (HBV) and hepatitis C virus (HCV). The aim of this study was to explore factors associated with the transition from first illicit drug use to first injection among drug users. Methods Using snowball sampling and convenience sampling through needle and syringe programmes (NSPs), we recruited 500 people who inject drugs (PWID) in Kermanshah, between September and December 2014. Trained interviewers collected data on socio-demographic characteristics, HIV testing and drug-related risk behaviors over the last month prior to interview using a structured questionnaire. Our main outcome variable was first illicit drug use to first injection (TIJ). TIJ was calculated by subtracting age at first drug injection from age of first illicit drug use. Results Overall, the average age at first drug use and injection were 21.4 [standard deviation (SD 5.6)] and 22.8 (SD 8.9), respectively. The average duration of injection was 6.0 (SD 4.6) years. Overall, the mean of TIJ for participants was 1.4 (IQR = 2, 4) years. Age of first injecting drug use negatively correlated with TIJ (R2 = 0.219, p = 0.001). Education level and socioeconomic status (SES), and negatively correlated with TIJ. Conclusion Some demographic factors and drug use characteristics including educational level, SES, knowledge of HIV status, age of initiating drug use, being a poly drug user and using methamphetamine were predictors of the time to transition.

Non-injection Drug Use and Injection Initiation Assistance among People Who Inject Drugs in Tijuana, Mexico

Although most people who inject drugs (PWID) report receiving assistance during injection initiation events, little research has focused on risk factors among PWID for providing injection initiation assistance. We therefore sought to determine the influence of non-injection drug use among PWID on their risk to initiate others. We used generalized estimating equation (GEE) models on longitudinal data among a prospective cohort of PWID in Tijuana, Mexico (Proyecto El Cuete IV), while controlling for potential confounders. At baseline, 534 participants provided data on injection initiation assistance. Overall, 14% reported ever initiating others, with 4% reporting this behavior recently (i.e., in the past 6 months). In a multivariable GEE model, recent non-injection drug use was independently associated with providing injection initiation assistance (adjusted odds ratio [AOR] = 2.42, 95% confidence interval [CI] = 1.39-4.20). Further, in subanalyses examining specific drug types, recent non-injection use of cocaine (AOR = 9.31, 95% CI = 3.98-21.78), heroin (AOR = 4.00, 95% CI = 1.88-8.54), and methamphetamine (AOR = 2.03, 95% CI = 1.16-3.55) were all significantly associated with reporting providing injection initiation assistance. Our findings may have important implications for the development of interventional approaches to reduce injection initiation and related harms. Further research is needed to validate findings and inform future approaches to preventing entry into drug injecting.

Post-war prevention: Emerging frameworks to prevent drug use after the War on Drugs

The prevention of drug use is one of the primary goals of the War on Drugs. However, despite investment in high-profile interventions such as social marketing campaigns and enforcement-based deterrence, these efforts have generally failed. With the emergence of novel policy frameworks to control and regulate drug use, a window of opportunity exists to test approaches to drug prevention that take into account existing evidence and the rights of individuals who use drugs. Specifically, there is a growing consensus that entry into drug use is a socially-defined event that individuals experience within particular socio-structural contexts. This understanding, coupled with a distinction between the value of preventing problematic drug use rather than all drug use, provides a useful framework within which to develop effective and rights-based approaches to drug prevention.

Progressive white matter impairment as a predictor of outcome in a cohort of opioid-dependent patient's post-detoxification

White matter impairment is associated with opioid dependence. However, the specific neuropathology related to opioid dependence is still not fully understood. The main aims of this study were to: (1) assess the association between white matter impairment and duration of dependence; (2) examine whether this impairment correlates with treatment outcome measures in opioid-dependent patients post-detoxification. Fifty-eight opioid-dependent patients participated, 20 females and 38 males, across three groups: less than 10 years use (n = 18), 10-15 years use (n = 26) and 16-25+ years use (n = 14). Diffusion tensor imaging was used to assess white matter impairment; whole brain voxel-wise analysis of fractional anisotropy, mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) were performed by Tract-Based-Spatial-Statistics to pinpoint abnormalities in white matter. The longer the subjects were dependent on opioids, the more widespread and severely the white-matter integrity was disrupted. A general linear model was used to examine patients who relapsed compared to those who were abstinent at follow-up. No statistical difference was found between groups (p > 0.05). Partial correlations were performed to investigate the relationship between clinical outcome measures (physical health, psychological well being and quality of life and hope for the future) and white-matter microstructural differences. Significant correlations were found between AD in the posterior corona radiata (L) and MD in the superior longitudinal fasciculus and a clinical measure for HOPE at 9-month follow-up. Nevertheless, it must be noted that the calculation of numerous correlations raises the possibility of a type I error, namely; to incorrectly conclude the occurrence of a significant correlation. The ability to investigate the structure-clinical relationship may improve our understanding of the pathological abnormalities associated with opioid dependence and has promise for use in evaluating future therapeutic outcomes in this population.

History of medication-assisted treatment and its association with initiating others into injection drug use in San Diego, CA

BACKGROUND

Medication-assisted treatment (MAT) remains the gold standard for the treatment of opioid use disorder. MAT also reduces the frequency of injecting among people who inject drugs (PWID). Relatedly, data suggest that PWID play a key role in the initiation of others into drug injecting by exposing injecting practices to injection-naïve drug users. Our primary objective was to test whether a history of MAT enrollment is associated with a reduced odds of PWID providing injection initiation assistance.

METHODS

Preventing Injecting by Modifying Existing Responses (PRIMER; NIDA DP2-DA040256-01), is a multi-site cohort study assessing the impact of socio-structural factors on the risk that PWID provide injection initiation assistance. Data were drawn from a participating cohort of PWID in San Diego, CA. The primary outcome was reporting ever providing injection initiation assistance; the primary predictor was reporting ever being enrolled in MAT. Logistic regression was used to model associations between MAT enrollment and ever initiating others into injecting while adjusting for potential confounders.

RESULTS

Participants (n = 354) were predominantly male (n = 249, 70%). Thirty-eight percent (n = 135) of participants reported ever initiating others into injection drug use. In multivariate analysis, participants who reported a history of MAT enrollment had significantly decreased odds of ever providing injection initiation assistance (Adjusted Odds Ratio [AOR]: 0.62, 95% Confidence Interval [CI]: 0.39-0.99).

CONCLUSIONS

These preliminary findings suggest an association between MAT enrollment and a lower odds that male PWID report providing injection initiation assistance to injection-naïve drug users. Further research is needed to identify the pathways by which MAT enrollment may impact the risk that PWID initiate others into drug injecting.

Correlates of Injection Drug Use Among Rural Appalachian Women

BACKGROUND

Limited research has focused on correlates of injection drug use (IDU) among high-risk subgroups of drug users, particularly women, who may be at increased risk for transmission of infectious diseases such as HIV and Hepatitis C. The purpose of this study is to better understand the contextual and health correlates of IDU among women living in rural Appalachia by examining (1) differences between injectors and noninjectors, and (2) the unique correlates of recent IDU and past IDU.

METHODS

This study involved random selection, screening, and face-to-face interviews with 400 rural Appalachian women from jails in one state. Analyses included descriptive statistics, multinomial logistic regression, and stepwise regression to identify significant correlates of recent IDU and past IDU compared to never injecting.

RESULTS

Findings indicated that 75.3% of this randomly selected sample reported lifetime injection of drugs. Contextual factors including drug use severity (RRR = 8.66, P < .001), more male sex partners (RRR = 1.01, P < .05), and having injecting partners (RRR = 7.60, P < .001) were robust correlates of recent injection practices.

CONCLUSIONS

This study makes an important contribution to understanding factors associated with IDU among rural Appalachian women drug users, which are strongly associated with both relational and health factors. Study findings on the specific factors associated with IDU risk have important implications for tailoring and targeting interventions that should include a focus on the relationship context reducing high-risk injection practices.

Risk Factors Associated with Unsafe Injection Practices at the First Injection Episode among Intravenous Drug Users in France: Results from PrimInject, an Internet Survey

Background. New drug use patterns may increase the risk of human immunodeficiency virus and hepatitis infections. In France, new injection patterns among youths with diverse social backgrounds have emerged, which may explain the persistently high rates of hepatitis C virus infection. This study explores factors associated with injection risk behaviours at first injection among users who began injecting in the post-2000 era. Methods. A cross-sectional study was conducted on the Internet from October 2010 to March 2011, through an online questionnaire. Multivariate logistic regression identified the independent correlates of needle sharing and equipment (cooker/cotton filter) sharing. Results. Among the 262 respondents (mean age 25 years), 65% were male. Both risk behaviours were positively associated with initiation before 18 years of age (aOR 3.7 CI 95% 1.3–10.6 and aOR 3.0 CI 95% 1.3–7.0) and being injected by another person (aOR 3.1 CI 95% 1.0–9.9 and aOR 3.0 CI 95% 1.3–7.1). Initiation at a party was an independent correlate of equipment sharing (aOR 2.6 95% CI 1.0–6.8). Conclusions. Results suggest a need for innovative harm reduction programmes targeting a variety of settings and populations, including youths and diverse party scenes. Education of current injectors to protect both themselves and those they might initiate into injection is critically important.

Experiences of and attitudes toward injecting drug use among marginalized African migrant and refugee youth in Melbourne, Australia

Little is known about injecting drug use (IDU) among people from culturally and linguistically diverse backgrounds in Australia. We interviewed 18 young people of African ethnicity (6 current/former injectors, 12 never injectors) about exposure and attitudes to IDU. Exposure to IDU was common, with IDU characterized as unnatural, risky and immoral. IDU was highly stigmatized and hidden from family and friends. There is a need for culturally appropriate programs to promote open dialogue about substance use to reduce stigma and prevent African youth who may use illicit drugs from becoming further marginalized.

The Risk Environment of Heroin Use Initiation: Young Women, Intimate Partners, and "Drug Relationships"

This paper examines young women's initiation to heroin use in the context of an intimate relationship based on data from a small-scale ethno-epidemiology of heroin use in Ireland, 2007-2009. The epidemiological sample included 120 young people, and life history interviews were conducted with a sub-sample of 40 youth aged 16-25 years. A detailed analysis of the "risk environment" of young women's heroin initiation highlights a complex interplay between women's agency and intimate partner influence. It is argued that dichotomous representations of women as victims or emancipated consumers do not adequately capture the complexity of women's initiation journeys. The study's limitations are noted and implications for drug use prevention and harm reduction strategies are discussed.

Factors associated with being asked to initiate someone into injection drug use

AIMS

Injection drug use initiation typically involves an established person who injects drugs (PWID) helping the injection-naïve person to inject. Prior to initiation, PWID may be involved in behaviors that elevate injection initiation risk for non-injectors such as describing how to inject and injecting in front of injection-naïve people. In this analysis, we examine whether PWID who engage in either of these behaviors are more likely to be asked to initiate someone into drug injection.

METHODS

Interviews with PWID (N = 602) were conducted in California between 2011 and 2013. Multivariate analysis was conducted to determine factors associated with being asked to initiate someone.

RESULTS

The sample was diverse in terms of age, race/ethnicity, and drug use patterns. Seventy-one percent of the sample had ever been asked to initiate someone. Being asked to initiate someone was associated with having injected in front of non-injectors (Adjusted Odds Ratio [AOR] = 1.80, 95% Confidence Interval [CI] = 1.12, 2.91), having described injection to non-injectors (AOR = 3.63; 95% CI = 2.07, 6.36), and doing both (AOR = 9.56; 95% CI = 4.43, 20.65) as compared to doing neither behavior (referent). Being female (AOR = 1.73; 95% CI = 1.10, 2.73) and non-injection prescription drug misuse in the last 30 days (AOR = 1.69; 95% CI = 1.12, 2.53) were also associated with having been asked to initiate someone.

CONCLUSION

Reducing initiation into injection drug use is an important public health goal. Intervention development to prevent injection initiation should include established PWID and focus on reducing behaviors associated with requests to initiate injection and reinforcing refusal skills and intentions among established PWID.

Women's injection drug practices in their own words: a qualitative study

Background

There are significant gender differences in injection drug practices and relative risks involved for women who inject drug compared with men. This qualitative study aims to explore the social, contextual, and behavioral dimensions of injecting practices among women who inject drugs.

Methods

Participants were selected by purposive venue-based sampling from a syringe exchange program in 2012–2013. In-depth interviews were conducted with 26 women to elicit detailed perspectives regarding injection drug use practices and women-focused decision-making. All interviews were transcribed verbatim and analyzed with Atlas.ti.

Results

Participant’s mean age was 43.2 years, 48% Caucasian, 36% African American, and 16% Latina, poorly educated, mostly single, and heroin self-injectors. Three themes emerged; a) transitioning from non-injection to injection drug use; b) patterns and variations of initiation to injecting; and c) shifting toward autonomy or reliance on others. Women were predominantly influenced to transition to injection drug use by other women with their claims that injecting was a way to curtail their daily drug expenditure. More than half the women received their first injection from another woman in their social network rather than a male sexual partner. Self-injecting women exhibited agency around the circumstances of injection safety and potential risks. Other women revealed that their inability to inject themselves could and did make them dependent on others for unsafe injection practices.

Conclusions

The finding that many women were influenced to transition to injection drug use and receive the first injection from a woman is contrary to literature claims that male sexual partners introduce and initiate women to injection drug use. Self-injecting women possessed capacity to act in a way that produced the results they wanted, not sharing prepared drugs or injecting equipment. In stark contrast, women assisted with injections could and did make them vulnerable to unsafe injecting. Findings support early prevention strategies that discourage women’s transition from non-injection to injection and development of female peer-driven experiential interventions to dispel myths for non-injection women and to increase personal capability to self-inject for women who require assistance with injecting, to reduce injection-related harm.

Young people at risk of transitioning to injecting drug use in Sydney, Australia: social disadvantage and other correlates of higher levels of exposure to injecting

While numerous studies have examined characteristics of young people who have recently initiated injecting, little attention has focused on young people who may be at high risk of transitioning to injecting. This study sought to examine the extent that socially disadvantaged young people were exposed to injecting, determine their level of hepatitis C (HCV) knowledge and identify correlates of higher injecting exposure. A cross-sectional survey was administered to 210 young people in 2010-2011 who were exposed to injecting drug use, but had not transitioned to injecting. Respondents were primarily recruited from youth services in metropolitan Sydney. Exposure to injecting in the previous 12 months was assessed with four items that examined whether close friends, romantic/sexual partners or family members/acquaintances injected drugs, and whether they were offered an injection. Most respondents had at least a few close friends who injected drugs (65%) and almost half had been offered drugs to inject in the previous 12 months (48%). It was less common for respondents to report having a partner who injects (11%). Correlates of higher injecting exposure were examined with multivariate ordinal regression. In the multivariate model, higher exposure to injecting was independently associated with the experience of abuse or violent crime [adjusted odds ratio (AOR) = 1.80] and reporting more favourable attitudes towards injecting (AOR = 0.86). Higher exposure to injecting was not independently associated with patterns or history of drug use. HCV knowledge was low to moderate and was not associated with higher exposure to injecting. That drug use was not independently associated with higher injecting exposure may suggest that exposure is shaped more by social disadvantage than by drug use patterns. Additional research is required to investigate this, using an improved measure of exposure to injecting.

Initiation Stories: An Examination of the Narratives of People Who Assist With a First Injection

BACKGROUND

Research in the area of initiation to injection drug use that focuses on the perspective of initiators, or those who help with a first injection, is rare.

OBJECTIVE

To explore the process of initiation to injection drug use from the point of view of initiators.

METHODS

Semi-structured, in-depth qualitative interviews were conducted at a harm reduction program in Toronto, Canada. Twenty participants who had injected drugs in the last 30 days and who reported ever having initiated another person to injection drug use were recruited. A narrative analytic approach was used to explore the spectrum of narratives surrounding their experiences initiating others to injection drug use.

RESULTS

Initiation events arise in a complex interplay of individual circumstances and social contexts. People who inject may assist with a first injection for a variety of reasons, from conceding to social pressure, to wanting to help reduce a perceived risk of harm, to assisting because it provides a sense of pride at possessing a skill or of having helped someone achieve a desired state, to assisting to obtain drugs or to cope with withdrawal, or a mix of several of these reasons at once.

CONCLUSIONS/IMPORTANCE

Narratives reveal that preventing all instances of initiation is unrealistic. Combining elements from existing interventions that focus on enhancing reluctance to assist with initiation with safer injection training has the potential to reduce initiations and perhaps reduce injection related harm for novices if initiation occurs.

Pattern of Drug Use and Associated Behaviors Among Female Injecting Drug Users From Northeast India: A Multi-Centric, Cross-Sectional, Comparative Study

BACKGROUND

Studies from developed countries document the presence of injecting drug use among females and significantly higher vulnerabilities and risks as compared with male injecting drug users (IDUs). Studies comparing vulnerabilities and drug use patterns between female and male IDUs are not available for developing countries.

OBJECTIVES

The aim of the study was to assess the drug use pattern and related HIV vulnerabilities among female IDUs and compare these findings with those from male IDUs from four states of Northeast India.

METHOD

The study used data collected as part of a nationwide study of drug use pattern and related HIV vulnerabilities among IDUs. Ninety-eight female and 202 male IDUs accessing services from harm reduction sites across the four states of Northeast region of India were chosen through random sampling methodology. Drug use pattern, injecting practices, and knowledge of HIV were assessed using a structured questionnaire.

RESULTS

Significantly higher proportion of female IDUs was uneducated, unemployed, reported their occupation as sex workers, and switched to injecting drug use faster as compared with male IDUs. Female IDUs practicing sex work differed significantly from those who did not with respect to frequency of daily injections, choice of drugs injected, and concomitant use of non-injecting drugs. More than half of female IDUs initiated sharing within the first month of injecting.

CONCLUSIONS

The study demonstrates that female IDUs differ from male IDUs in their drug use pattern, initiation into injection as well as injecting behavior, which would be an important consideration during designing of female-specific interventions.

Existe-t-il des différences entre les hommes et les femmes en ce qui concerne les problèmes de toxicomanie ?

La consommation et la dépendance aux drogues furent longtemps considérées comme un problème typiquement masculin. Néanmoins, bien que l’abus et la dépendance à l’alcool, au cannabis et à la nicotine soient encore plus répandus chez les hommes, les différences de genre en ce qui concerne les stimulants et les opiacés ont largement disparu. Il semblerait également que les motivations pour commencer à consommer, l’escalade vers la dépendance et les taux de cessation diffèrent chez les hommes et les femmes. Les raisons qui expliquent ces différences sont multiples et complexes. Nous allons examiner ici les données des études épidémiologiques et cliniques concernant la consommation de diverses drogues chez des hommes et chez des femmes en contexte des facteurs socioculturels, psychologiques et neurobiologiques.

Factors associated with initiating someone into illicit drug injection

AIMS

Most people who inject drugs (PWID) were first initiated into injection by a current PWID. Few studies have examined PWID who assist others into drug injection. Our goal is to describe the prevalence of and risk factors for initiating someone into injection in the last 12 months.

METHODS

We recruited a cross-sectional sample of PWID (N=605) in California from 2011 to 2013. We examined bivariate and multivariate risk factors for initiating someone into injection with a focus on behaviors that might encourage injection initiation such as injecting in front of non-PWID, describing how to inject to non-PWID, and willingness to initiate someone into drug injection.

RESULTS

Having initiated someone into injection was reported by 34% of PWID overall and 7% in the last 12 months. Forty-four PWID had assisted 431 people into injection in the past year. Factors independently associated with initiating someone into injection in the last 12 months were self-reported likelihood of initiating someone in the future (Adjusted Odds Ratio [AOR]=7.09; 95% Confidence Interval [CI]=3.40, 14.79), having injected another PWID in past month (AOR=4.05; 95% confidence interval [CI]=1.94, 8.47), having described how to inject to non-injectors (2.61; 95% CI=1.19, 5.71), and non-injection powder cocaine use in past month (AOR=4.97; 95% CI=2.08, 11.84) while controlling for study site.

CONCLUSION

Active PWID are important in facilitating the process of drug injection uptake. Interventions to reduce initiation should include efforts to change behaviors and intentions among PWID that are associated with injection uptake among others.

A comparison of risk factors for hepatitis C among young and older adult prisoners

Internationally, the prevalence of hepatitis C infection is higher among prisoners when compared to the general population, particularly among people who inject drugs. This study estimates the prevalence of, and compares the risk factors for, hepatitis C in young (< 25 years) and older (≥ 25 years) prisoners with a history of injection drug use. Participants were 677 sentenced prisoners in Queensland, Australia, with a lifetime history of injection drug use, recruited in the 6 weeks prior to release from custody. The prevalence of hepatitis C exposure was significantly lower in young prisoners than in older prisoners (20.7% vs. 29.4%, p = .03). Risk factors for hepatitis C varied between young and older prisoners. Young people who inject drugs and who have had shorter time at risk of hepatitis C exposure are an important target group for hepatitis C prevention efforts.

Interrupting the social processes linked with initiation of injection drug use: results from a pilot study

BACKGROUND

Injection drug use is a skill learned in social settings. Change the Cycle (CTC), a peer-delivered, one-session intervention, is designed to reduce among people who inject drugs (PIDs) injection initiation-related behaviours (i.e., speaking positively about injecting to non-injectors, injecting in front of non-injectors, explaining or showing a non-injector how to inject) and initiation of non-injectors. We hypothesized that participation in CTC would lead to reductions in initiation-related behaviours six months later.

METHODS

Using respondent driven sampling (RDS), 98 PIDs were recruited in Toronto, Canada to participate in pilot testing of CTC. The baseline session consisted of a structured interview, the peer-delivered CTC intervention, instructions regarding RDS coupon distribution, and an invitation to return in six months for a follow-up interview. For the 84 PIDs completing the six-month interview, we compared initiation-related behaviours at baseline with six-month follow-up.

RESULTS

The proportion of PIDs offering to initiate a non-injector was reduced from 8.4% (95% CI: 2.5, 15.9) at baseline to 1.59% (95% CI: 0.4, 3.7) at 6-month follow-up. The prevalence of speaking positively about injection to non-injectors also decreased significantly. The proportion of PIDs who helped a non-injector with a first injection at baseline was 6.2% (95% CI: 2.1, 11.3) and at follow-up was 3.5% (95% CI: 0.8, 7.1). Paired analyses of initiator baseline versus follow-up data showed a 72.7% reduction in initiation (95%CI: 47.7, 83.1).

CONCLUSIONS

While further refinements remain to be tested, pilot study results suggest that CTC holds promise as a prevention intervention.

Gender differences in circumstances surrounding first injection experience of rural injection drug users in the United States

BACKGROUND

Research has demonstrated that there can be substantial gender differences in circumstances surrounding initiation of injection drug use; however, little is known about the gendered dynamics of first injection in rural areas where syringe exchange is inaccessible or among those who predominantly inject prescription medications. The present study examines gender differences in first injection experience among rural residents who predominantly inject prescription opioids.

METHODS

Interview-administered questionnaires collected data from a sample of injection drug users (n=394) recruited from Appalachian Kentucky using respondent-driven sampling.

RESULTS

Women were more likely to have initiated injection due to social-pressure (p=0.001), received the drugs as a gift (p=0.011), initiated in their partner's home (p=0.004) and in their partner's presence (p<0.001), been injected by their partner (p<0.001), used an unclean syringe (p=0.026), and received the syringe from their partner (p<0.001). Women were also more likely to report having engaged in sexual intercourse before or after initiation (p<0.001). Men were more likely to have personally purchased the drugs (p=0.002), to have acquired the syringe from a pharmacy/clinic (p=0.004), and to have injected with a friend (p=0.001) or family member (p=0.020). Men were also more likely to have a friend administer the first injection (p=0.007).

CONCLUSIONS

In this population of rural drug users, notable gender differences in injection initiation were observed. Social pressure played a more substantial role in women's first injection experience, and male partners had an integral role in women's initiation.

Access to treatment for substance-using women in the Republic of Georgia: socio-cultural and structural barriers

BACKGROUND

In the Republic of Georgia, women comprise under 2% of patients in substance use treatment and to date there has been no empirical research to investigate what factors may facilitate or hinder their help-seeking behaviour or access to treatment services.

METHODS

This study included secondary analysis of in-depth interviews with 55 substance-using women and 34 providers of health-related services.

RESULTS

The roles and norms of women in Georgian society were identified as major factors influencing their help-seeking behaviour. Factors that had a negative impact on use of drug treatment services included an absence of gender-specific services, judgmental attitudes of service providers, the cost of treatment and a punitive legal position in regard to substance use. Having a substance-using partner served as an additional factor inhibiting a woman's willingness to seek assistance.

CONCLUSION

Within the context of orthodox Georgian society, low self-esteem, combined with severe family and social stigma play a critical role in creating barriers to the use of both general health and substance-use-treatment services for women. Education of the public, including policy makers and health care providers is urgently needed to focus on addiction as a treatable medical illness. The need for more women centred services is also critical to the provision of effective treatment for substance-using women.

Understanding barriers to sexual health service access among substance-misusing women on the South East coast of England

OBJECTIVES

Evidence suggests substance-misusing women (SMW) experience disproportionate sexual health morbidity and poor uptake of interventions including contraception and cervical screening, yet there has been little investigation of sexual health service access issues for this population.

METHODS

Twenty women with problem drug use in Hastings in South East England, UK participated in a one-to-one interview with a researcher to explore experiences and beliefs surrounding access to a range of sexual health service interventions. Transcripts were open-coded and themes were elicited and organised concerning barriers to access.

RESULTS

Drug-use lifestyles, trauma and low self-worth framed the lives of SMW and hindered sexual health service access through: depleted practical and emotional resources to enable attendance; high perceived emotional cost of discussing sexual histories, and coping with tests and unfavourable results; and low anticipated value of sexual health interventions due to low perception and minimisation of risk and perceived incompatibility between drug use and sexual well-being.

CONCLUSIONS

A range of practical, social and emotional barriers to sexual health service access exist for this population, presenting a context from within which use of services may come at considerable personal cost to SMW. Interventions addressing anticipated stigma and emotional, hygiene and fiscal concerns are warranted for this population.

Childhood maltreatment and illicit drug use in middle adulthood: the role of neighborhood characteristics

This paper examined whether childhood maltreatment increases the risk of living in neighborhoods with less desirable characteristics (i.e., more disorder and disadvantage, less social cohesion, social control and advantage, and fewer resources) in middle adulthood and whether these neighborhood characteristics influence subsequent illicit drug use. Using a prospective cohort design study, court documented cases of childhood abuse and neglect and matched controls (n = 833) were first interviewed as young adults (mean age = 29 years) from 1989 to 1995 and again in middle adulthood from 2000 to 2002 (mean age = 40 years) and 2003 to 2005 (mean age = 41 years). In middle adulthood, individuals with histories of childhood abuse and neglect were more likely to live in neighborhoods with more disorder and disadvantage and less social cohesion and advantage compared to controls and to engage in illicit drug use during the past year. Path analyses showed an indirect effect on illicit drug use via neighborhood disorder among maltreated children, even after accounting for drug abuse symptoms in young adulthood, although this was sex specific and race specific, affecting women and Whites. Overall, child abuse and neglect places children on a negative trajectory that dynamically influences negative outcomes at multiple levels into middle adulthood.

Boyfriends and injecting: the role of intimate male partners in the life of women who inject drugs in Central Java

The international literature shows that HIV-risk behaviour for women mostly occurs in the context of intimate relationships. Power imbalances in the social, economic and cultural spheres put women at risk. This paper addresses the roles of male partners in women's engagement in drug-use behaviour and drug-related HIV-risk behaviour in Indonesia. Data were gathered through in-depth interviews with 19 women who had injected drugs in the previous month in three sites in central Java. Most of the women had male partners who also injected drugs. Results show that male partners play a significant role in the initiation of drug use, the provision of drugs, injecting behaviour and in the constitution of women injectors' social networks. These findings suggest the need to develop couple-based interventions and to facilitate women-only groups as part of HIV prevention.

Retrospective accounts of injection initiation in intimate partnerships

BACKGROUND

The influence of family members, peers and sexual partners on initiation to injection drug use is well established. Furthermore, research on gender differences in injection initiation has recognized the increased vulnerability of women, in particular, to injection-related health risks, and the gendered nature of the injection initiation experience. Yet more research is needed on the interpersonal and structural dynamics that shape injection initiation within intimate partnerships.

METHODS

This paper draws on narrative data from semi-structured ethnographic interviews with 25, relatively stable, drug-using couples from two New York City neighbourhoods. The study was conducted between 2007 and 2009. Our analyses focus on retrospective accounts of injection initiation from IDUs who were initiated to injection (or initiated their partners) in current or former intimate partnerships. In particular we analyse narratives of injection initiation events where both partners participated as initiates or initiators.

RESULTS

Transition to injection within intimate partnerships was common, especially for women, and occurred in specific contexts. Structural and interpersonal dynamics, including the ubiquity of drugs in poor communities and the gendered nature of drug acquisition and use strategies, as well as the problem of increased drug tolerance, situational impediments to drug access, and the perceived cost-benefit of injecting, all influenced the process of initiation to injection drug use within couples. The data also suggest that, even when risks associated with injection initiation were understood, both pragmatic and emotional considerations within relationships tended to offset concerns about potential dangers.

CONCLUSION

The findings suggest the need for a broad range of interventions (including couples-focussed interventions) to minimize rates of injection initiation within intimate partnerships.

Initiation to drug injection among street youth: a gender-based analysis

OBJECTIVE(S)

To estimate the incidence rate of initiation into drug injection and to identify predictors of initiation into drug injection separately among street girls and boys.

DESIGN

Data from two consecutive prospective street youth cohort studies (1995-2001 and 2001-2005) were used to conduct these analyses, stratified by gender.

METHODS

Data were collected using semi-annual interviewer-administered questionnaires. Variables from the following domains were considered in Cox regression models: socio-demographic characteristics, early and current substance abuse, marginalization, childhood traumatic sexual events and injection exposure.

RESULTS

Of the 946 youth who had never injected drugs at study entry, 86.4% completed at least two questionnaires representing 243 girls and 574 boys. Incidence rates of injection of 7.0 and 5.9 per 100 person-years were observed among these girls and boys respectively. Among girls, cocaine or crack use (adjusted hazard ratio (AHR)=1.97), heroin use (AHR=2.86), homelessness (AHR=2.49) and hanging out regularly with people who inject (AHR=4.46) all independently increased risk of first injection. Among boys, age decreased risk of initiating injection (AHR=0.90/year), while cocaine or crack use (AHR=2.14), heroin use (AHR=3.56), homelessness before age 16 (AHR=1.68), incest or rape before age 14 (AHR=1.98) and hanging out regularly with people who inject (AHR=1.66) all independently increased this risk.

CONCLUSIONS

Our findings suggest similar rates of initiation among girls and boys; however, factors associated with initiation vary by gender. This might lead to the design of more effective programs to prevent initiation into drug injection.

Comparison of HIV risk by duration of injection drug use

Early studies documented an inverse association between the HIV risk and duration of injection among injection drug users (IDUs). Results from subsequent studies have been inconsistent. To examine this issue, we conducted interviews with 395 street-recruited active IDUs from 38 neighborhoods in New York City during 2005 and 2008. We observed no significant differences in drug or risky sex behaviors by duration of drug use among these IDUs. Despite this, continuing to tailor HIV prevention programs for these recent-onset IDUs is prudent. The study's limitations are noted.

Prevalence and correlates of needle-sharing among new and long-term injection drug users in southwest China

Three community-based surveys recruited 4,310 injection drug users (IDUs) in China from 2004 to 2006. Of the participants, 54.4% were ≤ 3-year new IDUs; 63.9% reported injecting more than two times daily; 31.5% shared needles in the last six months; 37.4% shared equipments in the last month; 30.2% reported their regular sex partners injected drugs; and 23.5% had commercial sex, with 52.2% reporting no condom use during last sex. The risky injection practices (sharing needles/equipments and high injection frequency) were less frequent among new IDUs, emphasizing that effective prevention needs to identify and intervene with IDUs early on. The study's limitations are noted.

Circumstances, pedagogy and rationales for injection initiation among new drug injectors

Injection drug use is especially risky for new injectors. To understand the social and environmental contexts in which risks occur, we interviewed individuals who had initiated injection within the past 3 years (n = 146, 69.2% male) about the circumstances and rationales for their initial injection events. Respondents typically initiated injection due to tolerance (49.3%) and/or for experimentation (61.1%). Most (86.2%) did not possess the technical skills required to self-inject, and relied on the assistance of someone older (58.5%). While low levels of syringe sharing (5.8%) were reported, a majority of respondents (60.5%) engaged in at least one type of behavioral risk. Female injectors were more likely than male injectors to rely on another individual (95.5 vs. 82.2%), often a sex partner (40.5 vs. 7.2%), for assistance. The diversity seen in early injection practices highlights the need for tailored prevention messages to reach this population prior to the onset of injection risk.

Substance abuse in women

Gender differences in substance use disorders (SUDs) and treatment outcomes for women with SUDs have been a focus of research in the last 15 years. This article reviews gender differences in the epidemiology of SUDs, highlighting the convergence of male/female prevalence ratios of SUDs in the last 20 years. The telescoping course of SUDs, recent research on the role of neuroactive gonadal steroid hormones in craving and relapse, and sex differences in stress reactivity and relapse to substance abuse are described. The role of co-occurring mood and anxiety, eating, and posttraumatic stress disorders is considered in the epidemiology, natural history, and treatment of women with SUDs. Women's use of alcohol, stimulants, opioids, cannabis, and nicotine are examined in terms of recent epidemiology, biologic and psychosocial effects, and treatment. Although women may be less likely to enter substance abuse treatment than men over the course of the lifetime, once they enter treatment, gender itself is not a predictor of treatment retention, completion, or outcome. Research on gender-specific treatments for women with SUDs and behavioral couples treatment has yielded promising results for substance abuse treatment outcomes in women.

Social influences upon injection initiation among street-involved youth in Vancouver, Canada: a qualitative study

BACKGROUND

Street-involved youth are a population at risk of adopting injection as a route of administration, and preventing the transition to injection drug use among street youth represents a public health priority. In order to inform epidemiological research and prevention efforts, we conducted a qualitative study to investigate the initiation of injection drug use among street-involved youth in Vancouver, Canada.

METHODS

Qualitative interviews with street youth who inject drugs elicited descriptions of the adoption of injection as a route of administration. Interviewees were recruited from the At-Risk Youth Study (ARYS), a cohort of street-involved youth who use illicit drugs in Vancouver, Canada. Audio recorded interviews were transcribed verbatim and a thematic analysis was conducted.

RESULTS

26 youth aged 16 to 26 participated in this study, including 12 females. Among study participants the first injection episode frequently featured another drug user who facilitated the initiation of injecting. Youth narratives indicate that the transition into injecting is influenced by social interactions with drug using peers and evolving perceptions of injecting, and rejecting identification as an injector was important among youth who did not continue to inject. It appears that social conventions discouraging initiating young drug users into injection exist among established injectors, although this ethic is often ignored.

CONCLUSION

The importance of social relationships with other drug users within the adoption of injection drug use highlights the potential of social interventions to prevent injection initiation. Additionally, developing strategies to engage current injectors who are likely to initiate youth into injection could also benefit prevention efforts.

Initiators: an examination of young injecting drug users who initiate others to injecting

Research about initiation to injecting drugs emphasises the role that relationships with others plays in the experience, suggesting investigations of initiation should include an examination of both initiates and initiators. This paper uses cross-sectional data collected from 324 young, early-career injecting drug users (IDU) to describe the socio-demographic characteristics, drug and injecting practices, and harm reduction knowledge and practices of people who report initiating others to injecting. Fifty-five participants (17%) reported giving someone else their first injection. They reported initiating a total of 128 other people within the first 5 years of their own injecting. Compared to non-initiators, initiators were more likely to pass on harm reduction information [odds ratios (OR): 2.36, 95% confidence intervals (CI): 1.26-4.40]. However, the quality of this information was unknown and initiators did not have more accurate knowledge of blood borne viruses (BBV) than non-initiators, and commonly obtained needles and syringes from sources where the sterility of the equipment could not be guaranteed.
