Correlates of Injection Drug Use Among Rural Appalachian Women

Impaired driving and other risky drug use and sex behaviors: a cross-sectional examination of high-risk rural women incarcerated in jail

Background: Despite women accounting for an increasing proportion of impaired drivers and higher rates of impaired driving and road fatalities in rural areas, little is known about rural women who drive impaired and their other risky behavior.Objective: The present study assessed the association between impaired driving history, risky substance use, and other drug- and sex-related risk behaviors in a sample of high-risk rural women incarcerated in jail.Methods: Four hundred women from three rural jails provided information about their impaired driving, drug use, injection drug use practices, and sex risk behaviors. Groups were stratified on whether they self-reported impaired driving in the year prior to incarceration. Impaired drivers (n = 260, M = 31.90 years old) were compared to women who did not drive impaired (n = 131, M = 34.42 years old) using MANCOVA and logistic regression analyses.Results: Impaired drivers had significantly (p < .05) higher substance use severity scores for cannabis, sedatives, and prescription opioids. Furthermore, impaired drivers were significantly (p < .05) more likely to have been the passenger of an impaired driver (78.08% vs. 53.44%), been an injection drug user (69.62% vs. 41.98%), had a casual sex partner (47.31% vs. 25.95%), and traded sex for drugs or money (31.15% vs. 15.27%) in the year prior to incarceration.Conclusions: This study found a consistent association between past year impaired driving and a range of drug- and sex-related risk behaviors in a sample of high-risk rural women incarcerated in jail. These findings highlight an opportunity to intervene in criminal justice settings to reduce multiple health risk behaviors.

Transactional sex among rural, justice-involved Appalachian women who use drugs

PURPOSE

Transactional sex is associated with an array of other health risk behaviors and adverse health outcomes, including HIV. However, despite concerns regarding a potential HIV outbreak, there is limited understanding of transactional sex among rural Appalachians who engage in high-risk behaviors. Thus, the current study describes the prevalence and correlates of transactional sex among a sample of rural, justice-involved Appalachian women who use drugs.

METHODS

Participants (N = 400) were randomly selected, screened, and interviewed face-to-face at 3 rural Appalachian jails in Kentucky. Bivariate analyses were used to examine differences between those who reported trading sex for drugs, money, goods, or services in the year prior to incarceration and those who had not, and multivariable logistic regression was used to examine independent correlates of transactional sex.

FINDINGS

On average, participants were 33 years old with 11 years of education. They were predominantly White (99.0%), about half (43.7%) reported lifetime transactional sex, and 25.9% reported past year transactional sex. Past year transactional sex was positively associated with experiencing money problems, substance use problem severity, injection drug use, unprotected sex with a casual partner, and number of sexual partners in the year prior to incarceration.

CONCLUSIONS

Results suggest that transactional sex is fairly common among rural Appalachian women who use drugs and are justice-involved and may signal other HIV-related risk behaviors. Given limited service availability throughout rural Appalachia, findings emphasize a need for increased access to risk-reduction interventions, including jail-based interventions, to educate vulnerable, hard-to-reach populations on the risks associated with HIV.

Helping Women Suffering from Drug Addiction: Needs, Barriers, and Challenges

Statistical data on the use of various psychoactive substances indicate a narrowing of previous differences in substance use between men and women. Data from studies conducted among women suffering from drug addiction are increasingly published, with the authors highlighting the specific needs of this group and the difficulties that women with addiction problems encounter. The current study aimed to identify the barriers and needs of this audience, both when seeking help and during treatment. The method used in the study was secondary content analysis. To identify publications describing the barriers and needs of women suffering from drug addiction, we searched the PubMed database to find publications that met the adopted research objective. We set the data search period to the last ten years to examine the timeliness of the issue under study. The search yielded 199 research reports. Twenty-three articles describing 21 studies were included in the final analysis. The selected publications dealt with the difficulties and challenges faced by women with addiction problems. Barriers to accessing treatment for this group, the needs, and the challenges of helping women suffering from addiction were identified. Results showed that the barriers are mainly stigma but also deficits in the therapeutic offerings for this group. The primary need was identified as the introduction of appropriate drug policies, and the challenges, unfortunately, are the still-reported gender inequalities. To improve the situation of women, regular attention to these issues and the need to include them in national health strategies is essential.

Behavioural Risk for HIV, Hepatitis B, and Hepatitis C Infections among a Population of Drug Users and Injectors across Four Regions in Ghana

Background

Blood borne infections such as HIV, Hepatitis B (HBV), and Hepatitis C (HCV) are of great importance to governments and their implementing partners, especially among people who use drugs (PWUD) and people who inject drugs (PWID). Prevalence and determinants of HIV, HBV, and HCV among PWUD and PWID in Ghana are not well established, the significance of this study.

Method

This assessment was a cross-sectional study implemented via the respondent driven sampling approach. A team of community advisory boards that comprised former users, current users, and civil society organizations were constituted to help in the implementation of the study. The study was conducted in four regions in Ghana. The assessment was based on a representation of populations of PWID and PWUD from the four regions. Efforts were made by the team to ensure adequate representation of women where feasible. A quantitative questionnaire was developed and used to obtain information on the respondents' sociodemographics, sexual behavior, substance use, and biological characteristics. The prevalence of HIV, HBV, and HCV among PWID and PWUD was determined using blood samples. First response and oral quick test for confirmation of HIV positivity were carried out, while SD bioline was used to test for the presence of HBV and HBC. Data were analyzed using the Bayesian generalized linear model via the binomial family of distributions under the logit link function with weak Cauchy and Normal distribution as prior.

Results

A total of 323 PWUD and PWID participants were interviewed across four regions of Ghana. The overall median age of the respondents was 36 (28, 43) years. The prevalence of HIV, HBV, and HCV infection in the study was 2.5%, 4.6%, and 5.9%, respectively. The prevalence of HIV, HBV, and HCV among drug users was 2.5% (95% CI: 0.7%–4.2%), 4.1% (95% CI: 1.8%–6.2%), and 6.7% (95% CI: 3.9%–9.4%), respectively. Most drug injectors and users started using and injecting drugs at ages less than 20 years and between 20 and 29 years, respectively. Drug users who identified themselves as part of the general population were 66% less likely to be tested HIV positive (POR = 0.34, CrI: 0.12–0.81) compared to sex workers. Part time employment respondents had fivefold odds (POR = 5.50, CrI: 1.20–16.16) of being HBV positive as against full-time employment.

Conclusion

Most of the injectors and users started drugs at an early age. Drug users and injectors are at higher risk of these infections because of associated risky sexual behaviors and risky injection practices. Harm reduction programs to help addicts who are willing to quit the practice are recommended.

Medications for opioid use disorder during pregnancy: Access and continuity in a state women's prison facility, 2016-2019

BACKGROUND

Although medications to treat opioid use disorder (MOUD) are the standard of care during pregnancy, there are many potential gaps in the cascade of care for pregnant people experiencing incarceration.

METHODS

We conducted a retrospective cohort study of pregnant people with opioid use disorder incarcerated in a Southeastern women's prison from 2016 to 2019. The primary outcomes were access to MOUD during incarceration and continuity in the community. We used descriptive statistics to summarize aspects of our sample and logistic regression to identify predictors of MOUD receipt during incarceration.

RESULTS

Of the 279 pregnant people with OUD included in the analysis, only 40.1% (n = 112) received MOUD during incarceration, including 67 (59.8%) who received methadone and 45 (40.1%) who received buprenorphine. Less than one-third of the participants were referred to a community MOUD provider (n = 83, 30%) on return to the community. Significant predictors of MOUD receipt included medium/close custody level during incarceration, incarceration during the latter portion of the study period, pre-incarceration heroin use, and receipt of pre-incarceration MOUD.

CONCLUSIONS

Although prisons can serve as an important site of retention in MOUD for some pregnant people, there were substantial gaps in initiation of MOUD and retention in MOUD among pregnant people with OUD imprisoned in the Southeast during the study period.

Polysubstance use and re-incarceration in the 12-months after release from jail: a latent transition analysis of rural Appalachian women

BACKGROUND

Rural areas have high rates of opioid and stimulant involved polysubstance use which are known to contribute to overdose. Justice-involved women are likely to have multiple substance use disorders and are particularly vulnerable in rural areas where treatment is limited.

OBJECTIVES

The research had three aims to (1) identify the patterns of polysubstance use of rural Appalachian justice-involved women, (2) examine how women's engagement in polysubstance use changed in the 12-months following initial release from jail, and (3) determine if women's changes in substance use patterns were associated with re-incarceration during the 12-months of post-release follow-up.

METHODS

A total of 339 women with recent substance use histories were randomly recruited from three rural jails. Latent transition analysis of women's substance use from baseline (in jail) to 6 and 12-months was examined, including the effect of re-incarceration on transitions (changes in substance use patterns).

RESULTS

Three latent classes were found: High Polysubstance/injection drug use (IDU) (36.3% baseline), Opioid/Benzo (Benzodiazepine) Involved Polysubstance Use (57.3% baseline), and Low Use (6.4% baseline). Polysubstance use classes were characterized by use of opioids and benzodiazepines; the High Polysubstance/IDU class was distinct in co-use and injection use of methamphetamine. Post-release, women transitioned to latent classes of reduced substance use and/or reduced injection drug use, particularly in the first six months. Women who were re-incarcerated during follow-up were likely to remain engaged in, or transition to, the High Polysubstance/IDU class (ORs: 3.14-46.56).

CONCLUSION

Justice-involved women in Appalachia reported risky polysubstance use. The first six-months post-release were a critical period for changes in substance use.

Discriminant Function Analyses: Classifying Drugs/Violence Victimization Typologies Among Incarcerated Rural Women

This study examined the relationship between drug use and violence victimization among incarcerated women in Appalachian Kentucky. The purpose of this study was to test the utility of Goldstein's tripartite conceptual framework among rural incarcerated women, by examining whether distinct drugs/violence nexus groups could be classified based on psychopharmacological, economic-compulsive, and systemic factors. This study used secondary data from a National Institute on Drug Abuse (NIDA)-funded grant focused on risk reduction among high-risk incarcerated women in Appalachia (N = 400). Predicted drugs/violence groups were developed using a series of discriminant function analyses. The data yielded three statistically significant discriminant models. Findings of the classified groupings indicated support for three distinct drugs/violence victimization subgroups. The psychopharmacological group showed the greatest prevalence (n = 181; Wilks's λ = .389, F = 3.94, p < .001), followed by the economic-compulsive group (n = 77; Wilks's λ = .584, F = 11.86, p < .001) and systemic group (n = 55) significant (Wilks's λ = .994, F = 2.247, p < .035). To date, this is the first study to report a relationship between systemic violence victimization among rural communities. These findings could offer novel considerations for theory development and implications for clinical practice regarding the drug-related risks for violence victimization among rural incarcerated women.

Women in the 2019 hepatitis C cascade of care: findings from the British Columbia Hepatitis Testers cohort study

BACKGROUND

Women living with hepatitis C virus (HCV) are rarely addressed in research and may be overrepresented within key populations requiring additional support to access HCV care and treatment. We constructed the HCV care cascade among people diagnosed with HCV in British Columbia, Canada, as of 2019 to compare progress in care and treatment and to assess sex/gender gaps in HCV treatment access.

METHODS

The BC Hepatitis Testers Cohort includes 1.7 million people who tested for HCV, HIV, reported cases of hepatitis B, and active tuberculosis in BC from 2000 to 2019. Test results were linked to medical visits, hospitalizations, cancers, prescription drugs, and mortality data. Six HCV care cascade stages were identified: (1) antibody diagnosed; (2) RNA tested; (3) RNA positive; (4) genotyped; (5) initiated treatment; and (6) achieved sustained virologic response (SVR). HCV care cascade results were assessed for women, and an 'inverse' cascade was created to assess gaps, including not being RNA tested, genotyped, or treatment initiated, stratified by sex.

RESULTS

In 2019, 52,638 people with known sex were anti-HCV positive in BC; 37% (19,522) were women. Confirmatory RNA tests were received by 86% (16,797/19,522) of anti-HCV positive women and 83% (27,353/33,116) of men. Among people who had been genotyped, 68% (6756/10,008) of women and 67% (12,640/18,828) of men initiated treatment, with 94% (5023/5364) of women and 92% (9147/9897) of men achieving SVR. Among the 3252 women and 6188 men not yet treated, higher proportions of women compared to men were born after 1975 (30% vs. 21%), had a mental health diagnosis (42% vs. 34%) and had used injection drugs (50% vs. 45%). Among 1619 women and 2780 men who had used injection drugs and were not yet treated, higher proportions of women than men used stimulants (64% vs. 57%), and opiates (67% vs. 60%).

CONCLUSIONS

Women and men appear to be equally engaged into the HCV care cascade; however, women with concurrent social and health conditions are being left behind. Treatment access may be improved with approaches that meet the needs of younger women, those with mental health diagnoses, and women who use drugs.

Healthcare stigma and HIV risk among rural people who inject drugs

INTRODUCTION

The HIV epidemic is increasingly penetrating rural areas of the U.S. due to evolving epidemics of injection drug use. Many rural areas experience deficits in availability of HIV prevention, testing and harm reduction services, and confront significant stigma that inhibits care seeking. This paper examines enacted stigma in healthcare settings among rural people who inject drugs (PWID) and explores associations of stigma with continuing high-risk behaviors for HIV.

METHODS

PWID participants (n = 324) were recruited into the study in three county health department syringe service programs (SSPs), as well as in local community-based organizations. Trained interviewers completed a standardized baseline interview lasting approximately 40 min. Bivariate logistic regression models examined the associations between enacted healthcare stigma, health conditions, and injection risk behaviors, and a mediation analysis was conducted.

RESULTS

Stigmatizing health conditions were common in this sample of PWID, and 201 (62.0 %) reported experiencing stigma from healthcare providers. Injection risk behaviors were uniformly associated with higher odds of enacted healthcare stigma, including sharing injection equipment at most recent injection (OR = 2.76; CI 1.55, 4.91), and lifetime receptive needle sharing (OR = 2.27; CI 1.42, 3.63). Enacted healthcare stigma partially mediated the relationship between having a stigmatizing health condition and engagement in high-risk injection behaviors.

DISCUSSION

Rural PWID are vulnerable to stigma in healthcare settings, which contributes to high-risk injection behaviors for HIV. These findings have critical public health implications, including the importance of tailored interventions to decrease enacted stigma in care settings, and structural changes to expand the provision of healthcare services within SSP settings.

Incidence and Prevalence of Incarceration in a Longitudinal Cohort of Women at Risk for Human Immunodeficiency Virus in the United States, 2007-2017

Background: To estimate the incidence, prevalence, frequency, and duration of incarceration and to identify risk factors for incarceration among women at risk for human immunodeficiency virus (HIV) in the United States. Methods: During semiannual study visits in a multicenter cohort study, 970 HIV sero-negative participants at risk for HIV were asked about their own incarceration (10/2007-09/2017) and incarceration of sexual partners (10/2013-09/2017). We used descriptive statistics and multivariable log-binomial regression to identify baseline predictors of incident incarceration. Results: Median follow-up time across the 970 participants was 5.5 years (IQR 3.5-9.5). Nearly half (n = 453, 46.7%) of participants were incarcerated during or before the study, and the incarceration rate was 5.5 per 100 person-years. In multivariable models, incident incarceration was associated with prior incarceration (RR 5.20, 95% CI: 3.23-8.41) and noninjection drug use (RR 1.57, 95% CI: 1.10-2.25). Conclusions: Incarceration is common for women at risk for HIV. Prevention interventions that address the complex interplay of drug use, sex exchange, and housing instability for women who have experienced incarceration have the potential to reach an important group of U.S. women at risk of HIV infection.

Risks for acquiring hepatitis C virus among women in the United States

OBJECTIVE

To conduct a literature review about the breadth of risks for acquiring hepatitis C virus (HCV) among women who are living in the United States.

DESIGN

A mixed research synthesis of qualitative, quantitative, and mixed-methods studies guided by the Socioecological Model and Theory of Gender and Power.

SAMPLE AND ANALYTIC STRATEGY

The sample consisted of 29 studies: 10 qualitative, 18 quantitative, and one mixed-methods studies. Data were analyzed using a segregated approach and integrated into a narrative synthesis of themes by components of the Socioecological Model.

RESULTS

Individual risks themes were drug use as a coping strategy, transition to injection drug use, and lack of awareness about HCV. Interpersonal risks themes were social norms of drug use and drug use and sexual activities. Community risks themes were community re-entry, housing instability, and community HCV resources. Societal risks themes are policies affecting drug markets and social construct of "worthlessness."

CONCLUSIONS

Findings highlight the need for comprehensive gender-specific HCV prevention strategies built around harm reduction. In partnership with women with lived experience, public health nurses can apply findings to build harm reduction collaborations aimed at implementing HCV risk-reduction or risk-elimination strategies.

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.

Social norms associated with nonmedical opioid use in rural communities: a systematic review

Prescription and illicit opioids were involved in over 42,000 deaths in the USA in 2016. Rural counties experience higher rates of opioid prescribing and, although opioid prescribing rates have fallen in recent years, the rate of decline is less in rural areas. The sociocultural context of rural life may impact opioid misuse in important ways; however, little research directly explores this possibility. We performed a systematic review of English-language manuscripts in U.S. context to determine what is known about social networks, norms, and stigma in relation to rural opioid misuse. Of nine articles identified and reviewed, two had only primary findings associated with social networks, norms, or stigma, five had only secondary findings, and two had both primary and secondary findings. The normalization of prescription opioid use along with environmental factors likely impacts the prevalence of opioid misuse in rural communities. Discordant findings exist regarding the extent to which social networks facilitate or protect against nonmedical opioid use. Lastly, isolation, lack of treatment options, social norms, and stigma create barriers to substance use treatment for rural residents. Although we were able to identify important themes across multiple studies, discordant findings exist and, in some cases, findings rely on single studies. The paucity of research examining the role of social networks, norms, and stigma in relation to nonmedical opioid use in rural communities is evident in this review. Scholarship aimed at exploring the relationship and impact of rurality on nonmedical opioid use is warranted.

Contraceptive use in Appalachian women who use drugs and were recruited from rural jails

This study describes a secondary data analysis of contraceptive use across the lifetime and within the six months prior to incarceration in a sample of 400 currently incarcerated women recruited from rural, Appalachian jails, who were using drugs prior to incarceration. Phase 1 (baseline) data from an NIH funded study were used to examine rates of contraceptive use, reasons for nonuse of condoms, and correlates of condom use. Results indicate that the majority (96.5%) of respondents reported lifetime use of contraceptives, and most (70.5%) had a history of using multiple methods, with male condoms, oral contraceptive pills, and contraceptive injections being the most commonly used methods. Almost 69% of respondents reported nonuse of contraceptives within the last six months, despite high rates of involvement in risky, intimate male partnerships prior to incarceration. Contraceptive use was found to be historically acceptable in this sample, in stark contrast to rates of use within the last six months prior to incarceration, suggesting that reproductive justice-informed, social work interventions to help improve current contraceptive use are warranted as a harm-reduction approach.

Risk factors for heroin use following release from jail or prison in adults in a Central Appalachian state between 2012-2017

Background

Corrections-involved adults with a history of opioid use disorder are at elevated risk of opioid overdose following release from correctional settings. Increased opioid prescribing restrictions and monitoring during a time when heroin is becoming cheaper and ubiquitous means that adults who misused prescription opioids prior to incarceration may be reentering communities at greater risk for heroin exposure and use.

Objectives

Determine risk factors of post-release heroin use among a sample of adults who participated in corrections-based drug treatment in Kentucky released between 2012 and 2017.

Methods

Survey data obtained as part of an ongoing evaluation of corrections-based drug treatment were examined.

Results

The final sample (N = 1,563) was majority male (80.9%). Nearly 11.0% reported past-year heroin use following their release. Depressive symptoms, polydrug use, and urban proximity were more common among participants reporting post-release heroin use. Heroin use 30 days prior to incarceration was associated with a 432.1% increase in odds of heroin use subsequent to incarceration. Post-release suicidal ideation increased odds of heroin use by 154.2%, whereas reporting satisfaction from social interactions decreased odds of use by nearly 60%. Post-release use of cocaine and diverted buprenorphine were associated with increased likelihood of heroin use during this time period, increasing odds by 469.1% and 265.9%, respectively. Residing in Central Appalachia subsequent to incarceration was associated with decreased likelihood of use.

Conclusions

In this sample, post-release heroin use was associated with concerning features, such as polydrug use, lack of social satisfaction, and suicidal ideation. These features can serve as clear targets for clinical intervention.

Characterization of diverted buprenorphine use among adults entering corrections-based drug treatment in Kentucky

BACKGROUND

Illicit, medically unsupervised use of buprenorphine (i.e., "diverted use") among vulnerable and underserved populations, such as corrections-involved adults, remains underexplored.

METHODS

Survey data (2016-2017) collected as part of a clinical assessment of incarcerated adults entering corrections-based substance use treatment in Kentucky were analyzed. For years examined, 12,915 completed the survey. Removing cases for participants who did not reside in Kentucky for >6 months during the one-year pre-incarceration period (n = 908) resulted in a final sample size of 12,007.

RESULTS

Over a quarter of the sample reported past-year diverted buprenorphine use prior to incarceration and 21.8 % reported use during the 30-days prior to incarceration, using 6.5 months and 14.3 days on average, respectively. A greater proportion of participants who reported diverted buprenorphine use had previously been engaged with some substance use treatment (77.0 %) and reported greater perceived need for treatment (79.4 %) compared to those who did not report use. Use was more likely among participants who were younger, white, male, and who reported rural or Appalachian residence. Diverted buprenorphine users also evidenced extensive polydrug use and presented with greater substance use disorder severity. Non-medical prescription opioid, heroin, and diverted methadone use were associated with increased odds of diverted buprenorphine use while kratom was not. Diverted methadone use was associated with a 252.9 % increased likelihood of diverted buprenorphine use.

CONCLUSIONS

Diverted buprenorphine use among participants in this sample was associated with concerning high-risk behaviors and may indicate barriers to accessing opioid agonist therapies for corrections-involved Kentucky residents, particularly those in rural Appalachia.

Factors Associated with Gabapentin Misuse among People Who Inject Drugs in Appalachian Kentucky

Gabapentin is misused to potentiate the euphoric effects of opioids, self-treat physical pain, and moderate opioid withdrawal symptoms. Because examinations of gabapentin misuse among people who inject drugs (PWID) are scant, the aim of this study is to identify factors associated with gabapentin misuse among this population. Methods: Data are drawn from a study examining the uptake of syringe service programs (SSPs) in Appalachian Kentucky. The sample includes 324 PWID who were age 18 and over and reported past month drug injection. Logistic regression models were constructed to examine recent (past 90 days) gabapentin misuse. Results: Participants are female (50.0%); Hispanic (2.2%), Black (1.5%), white (90.7%), and other race/ethnicity (4.6%). Mean age is 37. Participants reporting gabapentin misuse had higher odds of reporting (mis)use of marijuana, cocaine, methamphetamine, prescription opioids, benzodiazepines, prescription stimulants, fentanyl, and buprenorphine (p < .042); severe substance use disorder (p < .000); and recent physical pain (p < .003). In multivariable models, findings related to misuse of prescription opioids and buprenorphine; severe substance use disorder; and recent physical pain or discomfort, remained significant (p < .042). Conclusions: This is one of the first studies to examine gabapentin misuse among PWID. It is possible that individuals reporting recent gabapentin misuse are attempting to self-treat physical pain when healthcare is limited. Gabapentin may also be misused to achieve desired central nervous system effects and to potentiate opioid highs. Syringe service programs can educate PWID about the potential dangers of polydrug use involving gabapentin and to connect PWID with needed healthcare services.

Latent Profiles of Health and Reproductive Risk and Protective Factors among Women in Appalachia

Women who use opiates and are involved in the criminal justice system in Appalachia may be prone to adverse health outcomes. In this study, we performed a latent class analysis of risk and protective factors on 400 drug-using women recruited from rural, Appalachian jails. A two-profile solution best fit the data. Both profiles evinced low levels of condom use, reproductive and physical health screens, and STD history. However, the primary substantive difference between the profiles was partner risk behavior: the higher risk class had main male partners with histories of injection drug use and incarceration. Results suggest that interventions need to be tailored to unique profiles of risk and protective factors, which should include taking partner risk into consideration.

The opioid and related drug epidemics in rural Appalachia: A systematic review of populations affected, risk factors, and infectious diseases

Background/aims: To examine trends in rural Appalachian opioid and related drug epidemics during the past 10 years, including at-risk populations, substance use shifts and correlates, and associated infections. Methods: We conducted this review in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Seven databases were searched for quantitative studies, published between January 2006 and December 2017, of drug use, drug-related mortality, or associated infections in rural Appalachia. Results: Drug-related deaths increased in study states, and a high incidence of polydrug toxicity was noted. Rural substance use was most common among young, white males, with low education levels. A history of depression/anxiety was common among study populations. Prescription opioids were most commonly used, often in conjunction with sedatives. Women emerged as a distinct user subpopulation, with different routes of drug use initiation and drug sources. Injection drug use was accompanied by risky injection behaviors and was associated with hepatitis C. Conclusions: This review can help to inform substance use intervention development and implementation in rural Appalachian populations. Those at highest risk are young, white males who often engage in polysubstance use and have a history of mental health issues. Differences in risk factors among other groups and characteristics of drug use in rural Appalachian populations that are conducive to human immunodeficiency virus (HIV) spread also warrant consideration.

Non-Prescribed Buprenorphine Use Mediates the Relationship between Heroin Use and Kratom Use among a Sample of Polysubstance Users

In Asia, Mitragyna speciosa (e.g., "kratom") has been used to mitigate alcohol and drug dependence. Some preliminary findings suggest kratom's potential use as an informal harm-reduction method in the United States, such as an opioid substitute or as a means of lessening opioid withdrawal symptoms. To determine correlates of past-year kratom use among a sample of polysubstance users enrolled in residential recovery programs in Kentucky, an anonymous survey was completed by clients in April 2017. Logistic regression was used to identify significant associations with past-year kratom use. Of the final sample (N = 478), 10.4% reported past-year kratom use. Past-year heroin use, but not past-year prescription opioid (e.g., oxycodone, hydrocodone) use, was significantly associated with kratom use, such that individuals who reported past-year heroin use were 2.5 times more likely to also report past-year kratom use. Non-prescribed buprenorphine (i.e., Suboxone) use partially mediated the relationship between past-year heroin and kratom use by explaining 36% of the association between the two drugs. Though amphetamines were highly preferred, past-year use was negatively correlated with past-year kratom use. Rates of past-year kratom use were lower than rates of alcohol and illicit drug use. Kratom was not preferred over heroin or prescription opioids.

Synthetic Cathinone Use Among Polysubstance Users: Indirect Indicator of Indiscriminate Drug Taking or Preferred Drug of Abuse?

A survey pertaining to synthetic cathinone (SC) use was completed by 499 polysubstance users enrolled in a residential recovery program in the Southeastern United States. Of the final sample, 28% reported ever SC use. SC-users, compared with nonusers, were more often younger (32.7 vs. 36.0, p = .001), White (93.4% vs. 80.8%, p = .001), and on probation/parole since 2010 (80.9% vs. 70.9%, p = .032). SC-users evidenced extensive drug histories and were less likely to be enrolled in an urban-based program, compared to a rural, Appalachian-based program (73.8% vs. 86.6%, p = .001). Use of synthetic cannabinoids (adjusted odds ratio [AOR] = 1.9, p = .044), kratom (AOR = 1.7, p = .045), and inhalants (AOR = 2.3, p = .001) were significantly associated with SC use. Approximately 23% of SC-users preferred SCs to amphetamines or cocaine; however, only 3.6% ranked SC as their most preferred drug. Past-year SC use declined to 6.6%. Among polysubstance users in this sample, SC use may be a potential indicator of versatile and indiscriminate drug-taking.

Prevalence and Correlates of Electronic Cigarette Use Among a Clinical Sample of Polysubstance Users in Kentucky: Long Live the Cigarette?

BACKGROUND

E-cigarette use has increased in the US, yet, in some regions rates of cigarette use remain high.

PURPOSE

To describe the prevalence and features of lifetime and past-year e-cigarette use among a clinical sample of polysubstance users in Kentucky, and to determine significant associations of past-year e-cigarette use.

RESULTS

Of the final sample (N  =  497), 83.5% reported having ever used e-cigarettes and 97.2% reported having ever used cigarettes. These rates surpass those found among Kentucky's general population. Compared to those who did not report e-cigarette use, e-cigarette users were more likely to be younger ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover><mml:mrow><mml:mi>x</mml:mi></mml:mrow><mml:mo>¯</mml:mo></mml:mover></mml:math> = 33.4 vs. 43.6, p<.001) and White (88.2.1% vs. 62.5%, p = .001). E-cigarette users showed higher rates for lifetime incarceration (91.1% vs. 72.8%, p = .001) and past-year arrest (75.0% vs. 47.5%, p = .001). This group also presented with more severe substance use history and lower mean age for illicit drug use initiation ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover><mml:mrow><mml:mi>x</mml:mi></mml:mrow><mml:mo>¯</mml:mo></mml:mover></mml:math> = 13.8 vs. 16.4, p  =  .001). Approximately 65% of the sample reported past-year e-cigarette use and 96.6% reported past-year cigarette use. Logistic regression indicated that being younger (AOR = .973, p = .030), White (AOR = 1.92, .046), having a past-year arrest (AOR = 1.73, p = .047) and having used cigarettes (AOR = 8.93, p = .001) or kratom (AOR = 3.04, p = .025) within the past year were significantly associated with past-year e-cigarette use.

CONCLUSIONS

E-cigarette use was related to more severe drug-using patterns. Rates of dual tobacco use among this sample are high, particularly among younger individuals. In ecological contexts where cigarette use remains normative, it is likely that dual use will persist for nicotine-dependent, polysubstance-using individuals.

Characteristics of Prescription-Opioid-Impaired and Other Substance-Impaired Drivers in Rural Appalachian Kentucky

Previous studies have highlighted the prescription opioid epidemic in rural Appalachia and its associated risk behaviors; however, no studies have examined prescription-opioid-impaired driving as a consequence of this epidemic. The purpose of the present study was to describe prescription-opioid-impaired drivers in rural Appalachian Kentucky and examine how they are similar to and different from other substance-impaired drivers from the region. A sample of convicted DUI offenders from rural Appalachian Kentucky completed a confidential research interview focused on their substance use, mental health, and criminal activity. Prescription-opioid-impaired drivers (n = 33) were compared to other drug-impaired drivers (n = 29) and to alcohol-only-impaired drivers (n = 44). Overall, prescription-opioid-impaired drivers had a similar prevalence of illicit substance use and criminal activity, including impaired driving frequency, to other drug-impaired drivers, but had a higher prevalence of illicit substance use and more frequent impaired driving when compared to alcohol-only-impaired drivers. Study implications include the importance of comprehensive substance abuse assessment and treatment for DUI offenders and the need for tailored interventions for prescription-opioid-impaired and other drug-impaired drivers.

Plant Biomarker Recognition by Molecular Imprinting Based Localized Surface Plasmon Resonance Sensor Array: Performance Improvement by Enhanced Hotspot of Au Nanostructure

Detection of plant volatile organic compounds (VOCs) enables monitoring of pests and diseases in agriculture. We previously revealed that a localized surface plasmon resonance (LSPR) sensor coated with a molecularly imprinted sol-gel (MISG) can be used for cis-jasmone vapor detection. Although the selectivity of the LSPR sensor was enhanced by the MISG coating, its sensitivity was decreased. Here, gold nanoparticles (AuNPs) were doped in the MISG to enhance the sensitivity of the LSPR sensor through hot spot generation. The size and amount of AuNPs added to the MISG were investigated and optimized. The sensor coated with the MISG containing 20 μL of 30 nm AuNPs exhibited higher sensitivity than that of the sensors coated with other films. Furthermore, an optical multichannel sensor platform containing different channels that were bare and coated with four types of MISGs was developed to detect plant VOCs in single and binary mixtures. Linear discriminant analysis, k-nearest neighbor (KNN), and naïve Bayes classifier approaches were used to establish plant VOC identification models. The results indicated that the KNN model had good potential to identify plant VOCs quickly and efficiently (96.03%). This study demonstrated that an LSPR sensor array coated with a AuNP-embedded MISG combined with a pattern recognition approach can be used for plant VOC detection and identification. This research is expected to provide useful technologies for agricultural applications.

Partner Relationships and Injection Sharing Practices among Rural Appalachian Women

BACKGROUND

The role of relationships in initiating and maintaining women's risk behaviors has been established. However, understanding factors that may underlie partner relationships and women's risky drug use, particularly in rural contexts, is limited. This study is the first to examine the association between injecting partners and women's risky injection practices as a function of relationship power perception.

METHODS

Female participants were recruited from three rural jails in the Appalachian region. Women were selected randomly, provided informed consent, and screened for study eligibility criteria. This cross-sectional analysis focuses on women who inject drugs during the year before entering jail (n = 199).

MAIN FINDINGS

Approximately three-quarters (76%) reported having a recent main male sexual partner with a history of injection drug use. Although having a risky partner independently increased the likelihood of women reporting shared injection practices, perceptions of relationship power significantly moderated the effect on shared needle (adjusted odds ratio, 0.02; 95% CI, 0.003-0.23; p = .001) and shared works (adjusted odds ratio, 0.17; 95% CI, 0.03-0.95; p = .04) use.

CONCLUSIONS

This interaction indicated that, for women who inject drugs with a recent injecting male partner, greater perception of relationship power was associated with a decreased likelihood of shared injection practices. Implications for clinical assessment and intervention are discussed.
