Gender disparities in utilization and outcome of comprehensive substance abuse treatment among racial/ethnic groups

The moderating role of sex in the relationship between cannabis use treatment admission profile and treatment processes and outcomes: A gender perspective

BACKGROUND

Gender-specific interventions are crucial in addressing substance use disorders -particularly cannabis use disorder - as they allow for tailored therapeutic approaches and increase the likelihood of successful outcomes. However, differences in therapeutic processes and outcomes between males and females are often not observed, making the prognosis and development of such interventions more difficult.

OBJECTIVE

This study aimed to examine the moderating role of sex in the relationship between treatment admission profile characterized by indicators of cannabis use and sociodemographic sources of gender inequality (e.g., employment status) and adherence and outcome at discharge.

METHOD

A multicentric retrospective observational study was conducted with a sample of 3,814 outpatients diagnosed with cannabis use disorder. Electronic health records were used for data analysis.

RESULTS

The interaction between sex and the number of children, as well as pre-treatment cannabis use, predicted lower treatment adherence, particularly among females. Additionally, the interaction between sex and the number of children predicted outcomes at discharge, with females showing a higher likelihood of dropout compared to males.

DISCUSSION AND CONCLUSION

Enhanced comprehensive treatment with intensified contingency management programs should be prioritized for females (especially those with children) who have consumed cannabis in the month before treatment. Adopting a treatment policy framework incorporating sex/gender-sensitive therapist training and evaluative measures is essential for optimizing treatment outcomes for all patients.

Examining facilitative services for entry into substance use disorder treatment: A cluster analysis of treatment facilities

OBJECTIVES

We examined services to facilitate access to entering substance use disorder (SUD) treatment among a national sample of SUD treatment facilities.

METHODS

We analyzed data from the National Survey of Substance Abuse Treatment Services (N-SSATS) 2020. Facilities were included in the sample based on criteria such as SUD treatment provision and being in the U.S. Cluster analysis was conducted using variables including ownership, levels of care, and whether facilities provide services or accept payment options aimed at reducing treatment barriers. National and state-level data on the percentage of facilities in each cluster were presented.

RESULTS

Among N = 15,788 SUD treatment facilities four distinct clusters were identified: Cluster 1 consisted of for-profit and government outpatient facilities with high proportions of services to reduce barriers (22.2%). Cluster 2, comprised of non-profit outpatient facilities, offered the most comprehensive array of services to minimize barriers to treatment among all four clusters (25.2%). Cluster 3 included facilities with diverse ownership and care levels and provided a moderate to high degree of services aimed at reducing entry barriers to treatment (26.0%). Cluster 4 was primarily for-profit outpatient facilities with a low proportion of these services (26.6%).

CONCLUSIONS

This study revealed facility-level groupings with different services to reduce barriers to SUD treatment across various clusters of SUD treatment facilities. While some facilities offered extensive services, others provided fewer. Differences in cluster distributions point to possible facilitators to treatment access for some persons seeking admission to specific treatment facilities. Efforts should be made to ensure that individuals seeking SUD treatment can access these services, and facilities should be adequately equipped to meet their diverse needs.

Risk factors of substance use treatment gaps among a nationally representative sample of black American adults in relation to sexual minority status and health insurance coverage

BACKGROUND

Little research has investigated predictors of specialty substance use treatment gaps among Black adults. This study examined differential odds of experiencing self-reported, past-year treatment gaps among Black adults with respect to sexual minority status and health insurance coverage, accounting for social cofactors.

METHOD

This cross-sectional study comprised 36,098 Black Americans aged 18 and older who completed the 2015-2019 National Survey on Drug Use and Health (NSDUH) and provided responses for all selected survey items. Design-based multivariable logistic regression models were used to examine predictors of drug and alcohol treatment gaps.

RESULTS

Sexual minority Black adults reported greater odds of experiencing treatment gaps to specialty treatment (i.e., inpatient hospital, inpatient/outpatient rehabilitation facility, or mental health center) compared to Black heterosexuals in adjusted models (Gay or lesbian: AOR = 2.01, 95% CI = 1.39-2.89; Bisexual: AOR = 2.35, 95% CI = 1.77-3.12), with bisexual Black women experiencing the greatest odds (AOR = 3.10, 95% CI = 2.33-4.14). Black adults with no health insurance were significantly more likely to report substance use treatment gaps relative to their peers with health insurance coverage (AOR = 50, 95% CI = 1.26-1.78).

CONCLUSION

The results suggest a critical need for more investigations into patterns of specialty substance use treatment gaps within Black populations and for developing sexual identity-affirming mechanisms for closing the disparity gap, particularly for Black sexual minorities and those who lack health insurance coverage.

Substance Abuse Treatment, Critical Race Theory, and Counter-Storytelling, for the Black Emerging Adult Male

Black-emerging adult males face many barriers to the effective engagement in substance abuse treatment including stigma, lack of access to resources, and engagement with the criminal justice system. This case study introduces a group therapy and counter-storytelling intervention to understand and effectively mitigate some of these barriers. Counter-storytelling, derived from critical race theory (CRT) framework, focuses on marginalized individuals sharing how various aspects of society impact them, which is often different from the majority narrative. Through this intervention, Black-emerging adult males discussed the challenges they face when engaging in treatment, coping skills for barriers they face, and overcoming stigma of substance abuse recovery. Using a group therapy and counter-storytelling intervention, clinicians can begin to suspend how they traditionally think about treatment for Black-emerging adult males and engage in more effective practices to support this population.

Intersectional disparities in outpatient alcohol treatment completion by gender and race and ethnicity

BACKGROUND

Untreated alcohol use disorder (AUD) can have negative outcomes, including premature death. Completing specialty treatment for AUD can improve economic and educational outcomes. However, there are large racial and ethnic disparities in treatment completion, and how these disparities vary intersectionally (e.g., by gender and race and ethnicity) is unknown. Recent studies suggest that not using an intersectional approach can mask important disparities. We estimated disparities in AUD nonintensive outpatient treatment completion by gender alone, race and ethnicity alone, and intersectionally in a gender-by-race-and-ethnicity model. Accurately quantifying treatment completion disparities is critical not only for understanding healthcare disparities but reducing them to advance health equity.

METHODS

Data are from SAMHSA's 2017 to 2019 Treatment Episode Dataset-Discharges for adults aged 18+ who entered nonintensive outpatient treatment primarily for alcohol (n = 559,447 episodes; 30.3% women; 63.7% White, 18.0% Black, 14.4% Hispanic/Latinx, 2.1% American Indian/Alaska Native [AIAN], 1.0% Asian/Pacific Islander). Using the rank-and-replace method, treatment completion disparities were estimated by gender, race and ethnicity, and gender-by-race-and-ethnicity due to any reason other than differences in need for treatment, consistent with the Institute of Medicine's definition of a healthcare disparity.

RESULTS

The intersectional gender-by-race-and-ethnicity model identified the widest range of disparities among all models tested. Using this model, the largest disparities were identified for minoritized women's treatment episodes. Compared to White men whose completion rate was 60.79% (95% confidence interval [CI]: 60.06, 60.98), Black, Hispanic/Latina, AIAN, and Asian-American/Pacific Islander women had treatment episode completion rates that were 12.35 (CI: 12.33, 12.37), 9.08 (CI: 9.06, 9.11), 10.27 (CI: 10.22, 10.32), and 4.87 (CI: 4.78, 4.95) percentage points lower, respectively.

CONCLUSIONS

In the United States, treatment completion rates for non-intensive outpatient alcohol treatment episodes are significantly lower for minoritized women than White men. The extent of the disparity is not apparent in univariate models, highlighting the importance of an intersectional approach to understanding disparities in the completion of non-intensive outpatient treatment for AUD.

Identification of the socio-cultural barriers of drug addiction treatment in Iran

Introduction

Socio-cultural norms can either be encouraging or a barrier to addiction treatment. More, rigorous research is needed on nonindigenous models in addiction treatment, to better understand the role of socio-cultural differences.

Methods

The present qualitative study is part of the project, "The Inclusive Assessment of the Barriers of Drug Addiction Treatment Services in Iran," which was conducted in Tehran from 2018 to 2021. The participants consisted of eight people who used drugs, seven individual family members of the people who used drugs participants, seven service providers, and four policymakers. A purposeful sampling method was used for the selection of the participants, and the process continued until reaching the theoretical saturation of data. Analysis used the Graneheim and Lundman methods, classifying primary codes, the sub-themes, and themes were classified according to the similarities and differences between primary codes.

Finding

The most important socio-cultural barriers to addiction treatment in Iran are: unrealistic expectations of the family and society from the people who use drugs, addiction stigma, mistrust between various components of the treatment system, perceptions that professional substance use disorder treatment is inefficient and low uptake of that treatment, the disturbed relational boundaries between the people who use drugs and their relatives, the interweaving of treatment and ethical and religious principles, low acceptance of maintenance treatments, treatment focusing on short-term outcomes, and presence of facilitating backgrounds of using drugs.

Conclusions

The Iranian socio-cultural characteristics play an important role in the addiction treatment of the people who use drugs, so it is necessary for treatment interventions to be sensitive to these characteristics.

Understanding the role of financial capacity in the delivery of opioid use disorder treatment

Opioid treatment programs must have adequate financial capacity to sustain operations and deliver a high standard of care for individuals suffering from opioid use disorder. However, there is limited consistency in the health services literature about the concept and relationship of organizational financial capacity and key outcome measures (wait time and retention). In this study, we explored five common measures of financial capacity that can be applied to opioid treatment programs: (a) reserve ratio, (b) equity ratio, (c) markup, (d) revenue growth, and (e) earned revenue. We used these measures to compare financial capacity among 135 opioid treatment programs across four data collection points: 2011 (66 programs), 2013 (77 programs), 2015 (75 programs), and 2017 (69 programs). We examined the relationship between financial capacity and wait time and retention. Findings from the literature review show inconsistencies in the definition and application of concepts associated with financial capacity across business and social service delivery fields. The analysis shows significant differences in components of financial capacity across years. We observed an increase in average earned revenue and markup in 2017 compared to prior years. The interaction between minorities and markup was significantly associated with higher likelihood of waiting (IRR = 1.077, p < .05). Earned revenue (IRR = 0.225, p < .05) was related to shorter wait time in treatment. The interaction between minorities and equity ratio is also significantly associated with retention (IRR = 0.796, p < .05). Our study offers a baseline view of the role of financial capacity in opioid treatment and suggests a framework to determine its effect on client-centered outcomes.

Substance Use Treatment Utilization Among Women With and Without Human Immunodeficiency Virus

Background

Substance use (SU) contributes to poor health outcomes, yet limited data exist to inform strategies to optimize SU treatment among persons with human immunodeficiency virus (HIV). We describe SU and SU treatment utilization among women with and without HIV in the Women's Interagency HIV Study (WIHS).

Methods

We included data from women enrolled in WIHS from 2013 to 2020. Current SU was self-reported, nonmedical use of drugs in the past year, excluding use of only marijuana. SU treatment utilization was self-reported use of a drug treatment program in the past year. Multivariable regression models were used to investigate associations between participant characteristics and SU treatment.

Results

Among 2559 women (1802 women living with HIV [WWH], 757 women without HIV), 14% reported current SU. Among those with current SU (n = 367), 71% reported crack/cocaine followed by 40% reporting opioids, and 42% reported any treatment in the past year. The most common treatments were methadone (64%), Narcotics Anonymous (29%), inpatient programs (28%), and outpatient programs (16%). Among women using opioids (n = 147), 67% reported methadone use in the past year compared to 5% using buprenorphine/naloxone. Multivariable analysis showed lower odds of treatment utilization among WWH with concurrent alcohol or marijuana use. Visiting a psychiatrist/counselor was associated with higher odds of treatment. Among WWH, SU treatment was not associated with HIV-related clinical outcomes.

Conclusions

Treatment utilization was high, especially for methadone use. Our results highlight opportunities for accessing SU treatment for WWH, such as the need to prioritize buprenorphine and comprehensive, wraparound services in HIV care settings.

Opioid-stimulant trends in overdose toxicology by race, ethnicity, & gender: An analysis in Delaware, 2013-2019

Recent upticks of stimulant presence in overdose deaths suggest the opioid epidemic is morphing, which raises questions about what drugs are involved and who is impacted. We investigate annual and growth rate trends in combined opioid-stimulant overdose toxicology between 2013 and 2019 for White, Black, and Hispanic male and female decedents in Delaware. During these years, toxicology shifted to illegal drugs for all with fentanyl leading the increase and opioid-cocaine combinations rising substantially. While combined opioid-cocaine toxicology grew among Black and Hispanic Delawareans, White males continue to report the highest rates overall. These findings depart from historical patterns and may challenge existing opioid epidemic policies.

Identifying relative strength of methadone versus health and social services in comprehensive substance use disorder treatment using a variance decomposition approach

BACKGROUND

The purpose of this study is to identify the relative strengths of association of medication and health and social services in comprehensive substance use disorder (SUD) treatment.

OBJECTIVES

The study uses a novel variance decomposition method to assess the relative strength of association of six active ingredients of comprehensive SUD treatment: methadone medication, access services, SUD counseling, matched service ratio, client-provider relationship, and treatment duration.

METHODS

The study uses data from the National Treatment Improvement Evaluation Study (1992-1997), a dataset with an unusual number of services and service strategies measured. The data include 3012 clients from 45 SUD treatment programs. Linear mixed models are used to assess the relation of service variables to the outcome of posttreatment substance use. Variance decomposition methods are used to assess the relative importance of the ingredients in the treatment model.

RESULTS

Along with a random intercept and background variables, receipt of methadone accounted for the greatest relative strength of association at 35.4%, compared with 23.8% for treatment duration, 15.4% for client-provider relationship, and 11.2% for matched service ratio. Access and SUD counseling accounted for modest strengths of association at 1% and 3% each.

CONCLUSION

Findings indicate somewhat greater strength of association of methadone compared with other services and service strategies and overall, reinforce the importance of both medication and services and service strategies in the design and development of effective models of service delivery.

SIGNIFICANCE

This study, among the first to evaluate the relative importance of specific services and service strategies of comprehensive SUD treatment, provides insights relevant to the development of effective models of service delivery.

Child Abuse Prevention and Treatment Act, family care plans and infants with prenatal substance exposure: Theoretical framework and directions for future research

In May 2021, a reauthorization of the Child Abuse Prevention and Treatment Act (CAPTA) was introduced in the U.S. Senate. This reauthorization substantially amends provisions concerning infants affected by prenatal substance exposure and decidedly shifts the policy from a child safety- to a public health-focused approach to achieve the larger goals of healthy and safe child development and caregiver recovery from substance use disorder. Despite its honorable aspirations, no research has tested whether CAPTA "works". To advance scholarship on this policy, we summarize the service needs for this population and clarify how the CAPTA reauthorization aims to address these needs. We then apply a health utilization theory to understanding the mechanisms of effect on maternal-child outcomes. Based on this theoretical analysis, we discuss directions for future research.

Disparities in opioid treatment access and retention among women based on pregnancy status from 2006 to 2017

Background:

The purpose of this study is to assess differences in wait time and retention in opioid use disorder (OUD) treatment among a sample of pregnant and non-pregnant women from low-income urban communities in Los Angeles, California.

Methods:

Data were collected in 9 waves consisting of consecutive years from 2006 to 2011, and then including 2013, 2015, and 2017. The sample consisted of 12,558 women, with 285 being pregnant and 12,273 being non-pregnant. We compared pregnant women with non-pregnant women at admission on key characteristics and relied on two multilevel negative binomial regressions analyses to examine factors related to access (days on the waiting list) and retention (days in treatment).

Results:

We detected disparities existed in access and retention. Pregnant women spent less time waiting to initate treatment than non-pregnant women and, once in treatment, had longer treatment episodes. Among pregnant women, clients identifying as Latina or Other waited longer to enter treatment compared to clients identifying as non-Latina White or Black. Women entering residential waited longer than those entering methadone or counseling services. Pregnant women were more likely to be in treatment longer if they had mental health issues, greater parenting responsibilities (number of children less than 18), and greater SUD severity (number of prior treatment episodes).

Conclusions:

Findings suggest pregnant women’s access and retention can be improved through Medicaid coverage and through the implementation of a standard of care that includes MOUD (methadone) along with ancillary health and social services.

Black-White differences in barriers to specialty alcohol and drug treatment: findings from a qualitative study

The objective of this study was to explore, in-depth, differences in barriers to specialty alcohol and drug treatment services between Black and White participants with recent substance use disorders (SUD). We recruited 34 participants with a recent SUD of White and Black racial/ethnic descent for qualitative interviews. Interviews were coded to identify barriers to specialty treatment. We found that barriers related to stigma and lack of social support were more pervasive in the narratives of Blacks as compared to Whites. Results suggest that stigma and lack of perceived social support may impact Blacks more than Whites in seeking SUD treatment.

Using machine learning to advance disparities research: Subgroup analyses of access to opioid treatment

Objective

To operationalize an intersectionality framework using a novel statistical approach and with these efforts, improve the estimation of disparities in access (i.e., wait time to treatment entry) to opioid use disorder (OUD) treatment beyond race.

Data source

Sample of 941,286 treatment episodes collected in 2015–2017 in the United States from the Treatment Episodes Data Survey (TEDS‐A) and a subset from California (n = 188,637) and Maryland (n = 184,276), states with the largest sample of episodes.

Study design

This retrospective subgroup analysis used a two‐step approach called virtual twins. In Step 1, we trained a classification model that gives the probability of waiting (1 day or more). In Step 2, we identified subgroups with a higher probability of differences due to race. We tested three classification models for Step 1 and identified the model with the best estimation.

Data collection

Client data were collected by states during personal interviews at admission and discharge.

Principal findings

Random forest was the most accurate model for the first step of subgroup analysis. We found large variation across states in racial disparities. Stratified analysis of two states with the largest samples showed critical factors that augmented disparities beyond race. In California, factors such as service setting, referral source, and homelessness defined the subgroup most vulnerable to racial disparities. In Maryland, service setting, prior episodes, receipt of medication‐assisted opioid treatment, and primary drug use frequency augmented disparities beyond race. The identified subgroups had significantly larger racial disparities.

Conclusions

The methodology used in this study enabled a nuanced understanding of the complexities in disparities research. We found state and service factors that intersected with race and augmented disparities in wait time. Findings can help decision makers target modifiable factors that make subgroups vulnerable to waiting longer to enter treatment.

Gender disparities in opioid treatment progress in methadone versus counseling

BACKGROUND

In the United States, the high dropout rate (75%) in opioid use disorder (OUD) treatment among women and racial/ethnic minorities calls for understanding factors that contribute to making progress in treatment. Whereas counseling and medication for OUD (MOUD, e.g. methadone, buprenorphine, naltrexone) is considered the gold standard of care in substance use disorder (SUD) treatment, many individuals with OUD receive either counseling or methadone-only services. This study evaluates gender disparities in treatment plan progress in methadone- compared to counseling-based programs in one of the largest SUD treatment systems in the United States.

METHODS

Multi-year and multi-level (treatment program and client-level) data were analyzed using the Integrated Substance Abuse Treatment to Eliminate Disparities (iSATed) dataset collected in Los Angeles County, California. The sample consisted of 4 waves: 2011 (66 SUD programs, 1035 clients), 2013 (77 SUD programs, 3686 clients), 2015 (75 SUD programs, 4626 clients), and 2017 (69 SUD programs, 4106 clients). We conducted two multi-level negative binomial regressions, one per each outcome (1) making progress towards completing treatment plan, and (2) completing treatment plan. We included outpatient clients discharged on each of the years of the study (over 95% of all clients) and accounted for demographics, wave, homelessness and prior treatment episodes, as well as clients clustered within programs.

RESULTS

We detected gender differences in two treatment outcomes (progress and completion) considering two outpatient program service types (MOUD-methadone vs. counseling). Clients who received methadone vs. counseling had lower odds of completing their treatment plan (OR = 0.366; 95% CI = 0.163, 0.821). Female clients receiving methadone had lower odds of both making progress (OR = 0.668; 95% CI = 0.481, 0.929) and completing their treatment plan (OR = 0.666; 95% CI = 0.485, 0.916) compared to male clients and receiving counseling. Latina clients had lower odds of completing their treatment plan (OR = 0.617; 95% CI = 0.408, 0.934) compared with non-Latina clients.

CONCLUSIONS

Clients receiving methadone, the most common and highly effective MOUD in reducing opioid use, were less likely to make progress towards or complete their treatment plan than those receiving counseling. Women, and in particular those identified as Latinas, were least likely to benefit from methadone-based programs. These findings have implications for health policy and program design that consider the need for comprehensive and culturally responsive services in methadone-based programs to improve outpatient treatment outcomes among women.

Gender disparities in access and retention in outpatient methadone treatment for opioid use disorder in low-income urban communities

The purpose of this study was to detect and understand gender disparities in access and retention among outpatient methadone treatment programs located in low-income urban communities in Los Angeles, California. The study collected client- and program-level data in 4 waves in 2011, 2013, 2015, and 2017 from 34 publicly funded methadone treatment programs serving 11,169 clients with opioid use disorder (OUD). The sample included 29.8% female and 70.2% male clients, where 10.6% identified as Black or African American, 41.5% as Latino, 44.2% as non-Latino white, and 3.8% as Other. We conducted two multilevel negative binomial regression models to examine direct and moderated relationships related to both access (days on the waitlist) and retention (days in treatment) while accounting for clients clustered within programs. Gender disparities existed in both access and retention where women spent more time than men waiting to enter treatment but then remained in treatment longer. Further, female clients identifying as African American, Latino, and Other were at greater risk for shorter treatment duration than those who identified as non-Latino white and men. Overall, OUD clients receiving methadone treatment in low-income neighborhoods experienced barriers to access and retention in treatment associated with mental illness, family responsibilities, and use severity. OUD clients with MediCal insurance eligibility were consistently more likely to gain access to and remain in methadone treatment. Overall, findings call for improving treatment access and retention for women with OUD who receive methadone in outpatient methadone treatment programs through comprehensive, gender-specific, and evidence-based programming.

Women's Barriers to Specialty Substance Abuse Treatment: A Qualitative Exploration of Racial/Ethnic Differences

To explore barriers to specialty substance abuse treatment programs among women with recent substance use disorders by race/ethnicity. Qualitative interviews were conducted with 28 women of White, Black, and Latino racial/ethnic descent who reported a substance use disorder in the past 5 years. Interviews were conducted by telephone and were audio-recorded. A codebook was developed using the Theory of Planned Behavior to code and identify barriers within the domains of attitudes, subjective norms, and perceived control toward specialty treatment. Frequencies for coded themes were then compared across all participants and by race/ethnicity. We identified several key differences in barriers to treatment by race/ethnicity. Attitudinal barriers were more pervasive among the narratives of Latinas relative to Black and White women. Latinas were more likely to report not needing treatment and that treatment would not be effective; Latinas were the only group to describe cultural barriers to treatment. Within the subjective norms domain, namely stigma and lack of support, were key barriers. Stigma was more pervasive among the narratives of Latinas and Black women than White women; Latinas were more likely to report a lack of social support for using treatment than both Black and White women. Findings provide deeper insight into barriers that may be contributing to racial/ethnic disparities in the use of substance abuse treatment among women.

Stability in a large drug treatment system: Examining the role of program size and performance on service discontinuation

Background

Little is known about the stability of public drug treatment in the United States to deliver services in an era of expansion of public insurance. Guided by organizational theories, we examined the role of program size, and performance (i.e., rates of treatment initiation and engagement) on discontinuing services in one of the largest treatment systems in the United States.

Methods

This study relied on multi-year (2006–2014) administrative data of 249,029 treatment admission episodes from 482 treatment programs in Los Angeles County, CA. We relied on survival regression analysis to identify associations between program size, treatment initiation (wait time) and engagement (retention and completion rates) and discontinuing services in any given year. We examined program differences between discontinued versus sustained services in pre- and post-expansion periods.

Results

Sixty-two percent of programs discontinued services at some point between 2006 and 2014. Program size and rates of treatment retention were negatively associated with risk of discontinuing services. Proportion of female clients was also negatively associated with risk of discontinuing services. Compared to residential programs, methadone programs were associated with reduced likelihood of discontinuing services. Two interactions were significant; program size and retention rates, as well as program size and completion rates were negatively associated with risk of discontinuing services.

Conclusions

Program size (large), type (methadone), performance (retention) and client population (women) were associated with stability in this drug treatment system. Because more than 70% of programs in this system are small, it is critical to support their capacity to sustain services to reduce existing disparities in access to care. We discuss the implications of these findings for system evaluation and for responding to public health crises.

Cognitive Function Impairments Linked to Alcohol and Cannabis Use During Adolescence: A Study of Gender Differences

Major neurocognitive changes occur during adolescence, making this phase one of the most critical developmental periods of life. Furthermore, this phase in life is also the time in which youth substance use begins. Several studies have demonstrated the differential associations of alcohol and cannabis use concerning the neurocognitive functioning of both males and females. Past and contemporary literature on gender-specific effects in neuroscience of addiction is predominantly based on cross-sectional datasets and data that is limited in terms of measurement variability. Given the importance of gender-specific effects in addiction studies, and in order to address the two above-mentioned gaps in the literature, the present study aimed to compare neurocognitive functioning of male and female adolescents in the context of cannabis and alcohol use, while employing a longitudinal design with multiple repeated measurements. Participants were 3,826 high school students (47% female; mean age, 12.7), who were recruited from 31 high schools in the greater Montreal area. Participants were requested to complete annual surveys for five consecutive years, from 7th to 11th grade, assessing their alcohol/cannabis use and neurocognitive functioning (working memory, delayed recall memory, perceptual reasoning, and inhibition control). The analytical strategy focused on the longitudinal association between each predictor (female, male) and each of the outcomes (domains of neurocognitive functioning). Multilevel linear models assessed the association of alcohol and cannabis consumption and the four domains of neurocognitive functioning. Results revealed a gender by within-subject interaction, suggesting a weaker effect of yearly fluctuation of cannabis use on working memory among males compared to females. Our findings suggest a different pattern of neurocognitive impairment of female and male working memory after using cannabis over the course of adolescence. Early initiation of cannabis use potentially results in more spatial working memory deficits in female adolescents. This may negatively influence young females' capacity in academic settings and lead to significant impairment in adulthood, which critically decreases the individual's quality of life.

Factors Contributing to Substance Misuse Treatment Completion among Native Hawaiians, Other Pacific Islanders, and Asian Americans

Background: Research on substance abuse treatment completion (SATC) among Asian Americans and Native Hawaiian and Other Pacific Islanders (NHOPIs) is extremely limited despite growing concern of SA among these groups. Objectives: This study examined predictors of SATC among and within Asian, NHOPI, and White racial groups. Methods: 129,939 cases from the SA and Mental Health Services, Treatment Episode Data Set-Discharges-2016 were used in this study. Logistic regressions were employed to examine the differential impact of race on SATC and to investigate the moderating effect of race on the relationship between socioeconomic factors, type of substance used, and type of treatment setting on SATC. Results: NHOPIs were less likely to complete SA treatment than Whites. Within-group analysis indicated that NHOPIs who were in outpatient non-intensive treatment were more likely to complete treatment compared to ones in inpatient (more than 30 days), and outpatient intensive settings. In contrast, Asians and Whites in outpatient non-intensive treatment settings were less likely to complete compared to all other types of treatment settings. Older adults for Whites were more likely to complete treatment compared with younger adults. Age was not a significant predictor of SATC for Asians and NHOPIs. Asian and NHOPI methamphetamine users were less likely to complete treatment compared with White users. Conclusion/Importance: Findings highlight the importance of disaggregating Asians and NHOPIs in future SA studies to better understand how specific factors are relevant to each group, and to guide the development of cultural and race-informed treatments for these groups.

Understanding Social and Cultural Contexts of Alcohol Misuse in Mexican-Origin Hispanic Men

Evidence suggests that Hispanic and non-Hispanic White men (NHW) have comparable prevalence rates of alcohol use. However, Hispanic men consistently have higher prevalence rates of alcohol misuse compared with NHW men. Consequently, Hispanic men experience disproportionate levels of adverse health consequences of alcohol misuse when compared with NHW men. The aim of this study was to explore Hispanic male perspectives and opinions regarding alcohol use patterns that may lead to disparate rates of alcohol misuse in Hispanic males. Demographic data were collected with questionnaires. Twenty semistructured one-on-one interviews were completed in English and Spanish with Mexican-origin Hispanic men (age: 44.6 ± 11.3 years). A thematic analysis was conducted using a hybrid deductive-inductive strategy with an a priori codebook supplemented with iterative analysis of transcripts. Results suggest that alcohol misuse patterns in Hispanic males are influenced by an interaction between alcohol-related social norms and learned expressions of masculinity; a lack of knowledge of the alcohol-related health risks that further perpetuate the normalization of alcohol misuse; and expressions of masculinity and adaptive coping that lead to alcohol misuse as an escape from life stressors. Given the rapid expansion of the Hispanic population in the United States, and the disparate consequences of alcohol misuse in this population, it is imperative to consider the complex and often compounded impact of sociocultural norms and the social context on misuse-related behaviors. Viable prevention and treatment strategies should be addressed thought multicomponent, community-level strategies that more comprehensively address the complexities of alcohol misuse in this population.

Gender and Cultural Adaptations for Diversity: A Systematic Review of Alcohol and Substance Abuse Interventions for Latino Males

BACKGROUND

Latino men are disproportionately affected by the consequences of alcohol and substance abuse when compared to non-Latino white men. Latino men also face greater barriers to accessing, engaging, and completing alcohol and substance abuse treatment services. Culturally adapted interventions are promoted to overcome these barriers. However, the effectiveness of these efforts is unclear.

OBJECTIVES

The purpose of this review was to summarize the published evidence regarding gender-adapted and culturally adapted alcohol and substance abuse treatment that aims to improve physical, behavioral, and social outcomes in Latino men.

METHODS

A systematic literature search was conducted for articles reporting on culturally and/or gender-adapted alcohol and/or substance abuse interventions designed exclusively for Latino adults, including a Latino population sample of at least 10% and any proportion of Latino male participants. A thematic analysis based on predetermined themes was used to evaluate the nature of adaptations.

RESULTS

Searches yielded 2685 titles, resulting in 12 articles that fit review parameters. The most scientifically rigorous findings suggest culturally adapted interventions may outperform standard treatment. Nevertheless, a fraction of the interventions did not improve outcomes compared to standard treatment. Considering the scarce number of publications, it is difficult to discern if null findings reflect ineffective interventions or methodological limitations.

CONCLUSIONS

While studies are limited and findings are mixed, culturally tailored work shows promise. The growth rate of the Latino population and the current epidemic nature of substance abuse in the United States generate urgency to identify methods to diminish the disparate burden of alcohol and substance abuse in Latinos.

Understanding barriers to specialty substance abuse treatment among Latinos

BACKGROUND

National studies have documented that Latinos are less likely to use specialty substance abuse treatment (e.g., rehabilitation programs, in/out-patient services) than other racial/ethnic groups. Disparities in treatment utilization are particularly pronounced between Latinos and Whites. Few national studies have explicitly examined barriers to treatment by race/ethnicity, and current results are inconclusive. The purpose of this study was to gain a better understanding of barriers to specialty substance abuse treatment among Latinos.

METHODS

In 2017-2018, in-depth qualitative interviews were conducted with 54 White, Black, and Latino participants who met eligibility criteria for a recent substance use disorder. Participants were recruited via online ads and screened for eligibility through an online survey. Interview questions were grounded in the Theory of Planned Behavior (TBP): Participants were asked about treatment-related barriers in the domains of attitudes, subjective norms, and perceived control. Interviews were transcribed verbatim and coded by two independent coders. Barriers were compared across all interviews and by race/ethnicity.

RESULTS

Latinos were significantly more likely to report attitudinal and subjective norm barriers than their White and Black counterparts. Within the attitudes domain, results suggested that Latinos largely avoided specialty treatment due to barriers stemming from cultural factors, perceived treatment efficacy, recovery goals, and perceived treatment need. In the area of subjective norms, stigma and perceived lack of social support from family were more pervasive among Latinos' narratives. Lastly, in terms of perceived control, a minority of Latinos reported logistical barriers to treatment.

CONCLUSION

Specialty substance abuse treatment services have been found to be effective regardless of race/ethnicity. Understanding why Latinos use specialty treatment at low rates is key to reducing existing racial/ethnic disparities related to substance abuse. This study identified several malleable barriers that interventions can target to increase Latinos' utilization of treatment. These barriers may also be key to explaining Latino-White disparities in treatment utilization.

Prostate cancer health disparities: An immuno-biological perspective

Prostate cancer (PCa) is the most commonly diagnosed malignancy in males, and, in the United States, is the second leading cause of cancer-related death for men older than 40 years. There is a higher incidence of PCa for African Americans (AAs) than for European-Americans (EAs). Investigations related to the incidence of PCa-related health disparities for AAs suggest that there are differences in the genetic makeup of these populations. Other differences are environmentally induced (e.g., diet and lifestyle), and the exposures are different. Men who immigrate from Eastern to Western countries have a higher risk of PCa than men in their native countries. However, the number of immigrants developing PCa is still lower than that of men in Western countries, suggesting that genetic factors are involved in the development of PCa. Altered genetic polymorphisms are associated with PCa progression. Androgens and the androgen receptor (AR) are involved in the development and progression of PCa. For populations with diverse racial/ethnic backgrounds, differences in lifestyle, diet, and biology, including genetic mutations/polymorphisms and levels of androgens and AR, are risk factors for PCa. Here, we provide an immuno-biological perspective on PCa in relation to racial/ethnic disparities and identify factors associated with the disproportionate incidence of PCa and its clinical outcomes.

Gender and ethnic differences in primary care patients' response to computerized vs. in-person brief intervention for illicit drug misuse

This study is a secondary analysis from a randomized clinical trial of computerized vs. in-person brief intervention (BI) for illicit drug misuse among adult primary care patients (N=359; 45% Female; 47% Hispanic) with moderate-risk illicit drug misuse as measured by the World Health Organization's Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). This study examined differences in response to the two brief intervention strategies (both based on motivational interviewing) on the basis of gender and ethnicity, comparing non-Hispanic males, non-Hispanic females, Hispanic males, and Hispanic females. Participants were assessed at baseline, 3-, 6-, and 12-month follow-up with the ASSIST. Trajectories in Global Continuum of Illicit Drug Risk Scores were examined using a generalized linear mixed model. There were significant differences in response to computerized vs. in-person BI over time on the basis of gender-ethnic subgroups (Gender×Ethnicity×Condition×Time interaction; p=0.03), with Hispanic males tending to respond more favorably to the computerized BI and Hispanic females tending to respond more favorably to the in-person BI. There was no clear differentiation in response to the two BIs among non-Hispanic males, while among non-Hispanic females the pattern of change converged following baseline differences. Consideration of gender and ethnic differences in future studies of BI is warranted.

Sex and gender differences in substance use disorders

The gender gap in substance use disorders (SUDs), characterized by greater prevalence in men, is narrowing, highlighting the importance of understanding sex and gender differences in SUD etiology and maintenance. In this critical review, we provide an overview of sex/gender differences in the biology, epidemiology and treatment of SUDs. Biological sex differences are evident across an array of systems, including brain structure and function, endocrine function, and metabolic function. Gender (i.e., environmentally and socioculturally defined roles for men and women) also contributes to the initiation and course of substance use and SUDs. Adverse medical, psychiatric, and functional consequences associated with SUDs are often more severe in women. However, men and women do not substantively differ with respect to SUD treatment outcomes. Although several trends are beginning to emerge in the literature, findings on sex and gender differences in SUDs are complicated by the interacting contributions of biological and environmental factors. Future research is needed to further elucidate sex and gender differences, especially focusing on hormonal factors in SUD course and treatment outcomes; research translating findings between animal and human models; and gender differences in understudied populations, such as those with co-occurring psychiatric disorders and gender-specific populations, such as pregnant women.

Drug use among Asian Americans: Differentiating use by acculturation status and gender

This study examined past-year drug use among Asian Americans with respect to ethnic subgroup, acculturation, and gender differences. Survey data were collected during the National Latino and Asian American Survey, a national epidemiological household survey of behavioral health prevalence and service utilization rates. The analytical sample consisted of 505 Filipino, 598 Chinese, 518 Vietnamese, and 466 other Asian respondents. Results indicated that among ethnic subgroups, Filipinos had the highest rates of drug use. Among all Asian Americans, those who were born in the United States, those with higher levels of English proficiency, males, those who were younger, those with lifetime prevalence of a major depressive episode, and those who were frequent drinkers were all more likely to have reported past-year drug use. Findings suggest the need to better understand the heterogeneous character of Asian American drug use when considering the provision of culturally competent and linguistically appropriate prevention and treatment services.

Substance Use Disorder Treatment Services for Women in the Veterans Health Administration

PURPOSE

The present study used national Veterans Health Administration (VHA) facility-level data to examine the extent of women's specialty substance use disorder (SUD) treatment programming in the VHA. In addition, the study compared facilities with women's specialty SUD programming with facilities without to determine whether having this programming was associated with serving other special patient populations, treatment staffing, and breadth of service provision.

METHODS

The study used data from the VHA Program Evaluation and Resource Center's Drug and Alcohol Program Survey, conducted in 2015 (100% response rate among VHA specialty SUD treatment programs). Program responses were calculated at the facility level (n = 140 VHA facilities).

MAIN FINDINGS

The majority of VHA facilities (85%) provided women veterans with SUD-specific individual psychotherapy. However, only 30% of facilities provided SUD-specific groups for women only, and only 14% provided SUD-posttraumatic stress disorder groups for women only in specialty SUD treatment. VHA facilities with greater numbers of specialty SUD treatment staff members, a greater breadth of staff roles, and a broader scope of treatment services, activities, and practices were more likely to provide women-only groups.

CONCLUSIONS

Because the number of women veterans in specialty SUD treatment is likely to continue to grow, these data serve as a benchmark against which future administrations of the Drug and Alcohol Program Survey will document the extent to which VHA services are responsive to their needs.

Influence of gender and race/ethnicity on perceived barriers to help-seeking for alcohol or drug problems

This study examines reasons why people do not seek help for alcohol or drug problems by gender and race/ethnicity using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative survey. Multivariate models were fit for 3 barriers to seeking help (structural, attitudinal, and readiness for change) for either alcohol or drug problems, controlling for socio-demographic characteristics and problem severity. Predicted probabilities were generated to evaluate gender differences by racial/ethnic subgroups. Over three quarters of the samples endorsed attitudinal barriers related to either alcohol or drug use. Generally, women were less likely to endorse attitudinal barriers for alcohol problems. African Americans and Latina/os were less likely than Whites to endorse attitudinal barriers for alcohol problems, Latina/os were less likely than Whites to endorse readiness for change barriers for alcohol and drug problems, however, African Americans were more likely to endorse structural barriers for alcohol problems. Comparisons within racial/ethnic subgroups by gender revealed more complex findings, although across all racial/ethnic groups women endorsed attitudinal barriers for alcohol problems more than men. Study findings suggest the need to tailor interventions to increase access to help for alcohol and drug problems that take into consideration both attitudinal and structural barriers and how these vary across groups.

Racial and Ethnic Differences in Substance Use Diagnoses, Comorbid Psychiatric Disorders, and Treatment Initiation among HIV-Positive and HIV-Negative Women in an Integrated Health Plan

Access to substance use disorder (SUD) treatment is a critical issue for women with HIV. This study examined differences in SUD diagnoses, comorbid psychiatric diagnoses, and predictors of SUD treatment initiation among a diverse sample of HIV-positive women (n = 228) and a demographically similar cohort of HIV-negative women (n = 693). Diagnoses and service utilization data were obtained from electronic health records of members of a large integrated healthcare system in Northern California. HIV-positive women were less likely to initiate SUD treatment. Significant racial/ethnic differences were found among both HIV-positive and HIV-negative women with respect to SUD diagnosis type and diagnosis of comorbid psychiatric disorders. Among the HIV-negative women, rates of SUD treatment initiation were lower for black women than for white or Latina women. Multivariable logistic regression models showed that alcohol, cannabis, and opiate diagnoses were predictive of SUD treatment initiation for both cohorts, while amphetamine diagnoses, comorbid depressive disorder, and being white or Latina were predictive of SUD treatment initiation for HIV-negative, but not HIV-positive, women. Findings suggest that clinicians need to be aware of differences in substances of abuse, comorbid psychiatric disorders, and to consider the demographic and social factors that may contribute to differences in SUD treatment initiation among HIV-positive and HIV-negative women.

The Prevalence of and Factors Associated with Alcohol-Related Problems in a Community Sample of African American Women

Purpose. This study examines the prevalence of alcohol-related problems, the factors underlying these problems, and whether or not there is evidence of syndemic effects in a community population of southern, urban African American women. Methods. Questionnaire-based interviews were conducted with 817 women, all African American, from 80 targeted census block groups in Atlanta, Georgia. Results. Most of the alcohol users (67.8%) experienced at least one problem as a result of their alcohol (ab)use, with most women experiencing two or more such problems. Eight factors were found to be associated with experiencing more alcohol problems: being aged 30 or older, having had no recent health insurance, lower levels of educational attainment, self-identifying as lesbian or bisexual, experiencing greater amounts of childhood maltreatment, greater impulsivity, perceiving one's local community or neighborhood to be unsafe, and having a larger number of criminally involved friends. Conclusions. Drinking-related problems were prevalent in this population. Numerous factors underlie the extent to which African American women experienced problems resulting from their alcohol use. There is strong evidence of syndemic-type effects influencing drinking problems in this population, and future efforts to reduce the negative impact of alcohol (ab)use ought to consider the adoption of programs using a syndemics' theory approach.

Gender Differences in Emergency Department Visits and Detox Referrals for Illicit and Nonmedical Use of Opioids

INTRODUCTION

Visits to the emergency department (ED) for use of illicit drugs and opioids have increased in the past decade. In the ED, little is known about how gender may play a role in drug-related visits and referrals to treatment. This study performs gender-based comparison analyses of drug-related ED visits nationwide.

METHODS

We performed a cross-sectional analysis with data collected from 2004 to 2011 by the Drug Abuse Warning Network (DAWN). All data were coded to capture major drug categories and opioids. We used logistic regression models to find associations between gender and odds of referral to treatment programs. A second set of models were controlled for patient "seeking detox," or patient explicitly requesting for detox referral.

RESULTS

Of the 27.9 million ED visits related to drug use in the DAWN database, visits by men were 2.69 times more likely to involve illicit drugs than visits by women (95% CI [2.56, 2.80]). Men were more likely than women to be referred to detox programs for any illicit drugs (OR 1.12, 95% CI [1.02-1.22]), for each of the major illicit drugs (e.g., cocaine: OR 1.27, 95% CI [1.15-1.40]), and for prescription opioids (OR 1.30, 95% CI [1.17-1.43]). This significant association prevailed after controlling for "seeking detox."

CONCLUSION

Women are less likely to receive referrals to detox programs than men when presenting to the ED regardless of whether they are "seeking detox." Future research may help determine the cause for this gender-based difference and its significance for healthcare costs and health outcomes.

John Henryism Active Coping as a Cultural Correlate of Substance Abuse Treatment Participation Among African American Women

The rates of illicit drug use among African American women are increasing, yet African American women are least likely to participate in treatment for substance use disorders when compared to women of other racial groups. The current study examined family history of substance use, perceived family support, and John Henryism Active Coping (JHAC) as correlates to seeking treatment for substance abuse. The underlying theoretical frame of JHAC (James et al., 1983) suggests that despite limited resources and psychosocial stressors, African Americans believe that hard work and self-determination are necessary to cope with adversities. The current study is a secondary data analyses of 206 drug-using African American women (N=104 urban community women with no criminal justice involvement and N=102 women living in the community on supervised probation) from urban cities in a southern state. It was expected that African American women with a family history of substance abuse, higher levels of perceived family support, and more active coping skills would be more likely to have participated in substance abuse treatment. Step-wise logistic regression results reveal that women on probation, had children, and had a family history of substance abuse were significantly more likely to report participating in substance abuse treatment. Perceived family support and active coping were significant negative correlates of participating in treatment. Implication of results suggests coping with psychosocial stressors using a self-determined and persistent coping strategy may be problematic for drug-using women with limited resources.

Drug use and service utilization among Hispanics in the United States

PURPOSE

To examine illicit drug use and service utilization patterns of US-born and foreign-born Hispanics in the United States.

METHODS

Hispanic respondents 18 years and older in the NESARC were categorized as being of Mexican (n = 3,556), Puerto Rican (n = 785), Cuban (n = 346), Central American (n = 513), or South American (n = 381) origin. We examined lifetime prevalence of drug use and substance abuse treatment utilization patterns for US-born and Hispanic immigrants across subgroups.

RESULTS

Lifetime prevalence of drug use was greater among US-born Hispanics than Hispanic immigrants after controlling for age, gender, income, education, urbanicity, parental history of drug use problems and lifetime DSM-IV mood/anxiety disorders. Both US-born and immigrant Hispanic drug users were less likely than non-Hispanic white drug users to have utilized any form of substance abuse treatment (US-born AOR = 0.89, immigrant AOR = 0.64) and more likely to have utilized family or social services (US-born AOR = 1.17, immigrant AOR = 1.19). Compared to US-born Hispanic drug users, Hispanic immigrant drug users were less likely to have used any form of substance abuse treatment (AOR = 0.81) and were more likely to have utilized family or social services (AOR = 1.22).

CONCLUSION

Strategies to increase engagement and retention of Hispanic drug users in substance abuse treatment include increasing access to linguistically and culturally competent programs that address unmet family and social needs. Further studies examining differences in drug use and service utilization patterns within Hispanic subgroups are needed.

Paths to improving engagement among racial and ethnic minorities in addiction health services

Background

Members of racial and ethnic minority groups are most likely to experience limited access and poor engagement in addiction treatment. Research has been limited on the role of program capacity and delivery of comprehensive care in improving access and retention among minorities with drug abuse issues. The goal of this study was to examine the extent to which access and retention are enhanced when racial and ethnic minorities receive care from high-capacity addiction health services (AHS) programs and via coordination with mental health and receipt of HIV testing services.

Methods

This multilevel cross-sectional analysis involved data from 108 programs merged with client data from 2011 for 13,478 adults entering AHS. Multilevel negative binomial regression models were used to test interactions and indirect relationships between program capacity and days to enter treatment (wait time) and days in treatment (retention).

Results

Compared to low-capacity programs and non-Latino and non-African American clients, Latinos and African Americans served in high-capacity programs reported shorter wait times to admission, as hypothesized. African Americans also had longer treatment retention in high-capacity programs. Receipt of HIV testing and program coordination of mental health services played an indirect role in the relationship between program capacity and wait time.

Conclusions

Program capacity and coordinated services in AHS may reduce disparities in access to care. Implications for supporting low-capacity programs to eliminate the disparity gap in access to care are discussed.

Utilization of Substance Abuse Treatment: Gender Differences among Participants in an Aftercare Program

This study examined gender differences in the utilization of substance abuse treatment including inpatient, outpatient, and self-help services, using existing data sets from a National Institute on Drug Abuse study that enrolled 78 females and 141 males in a mixed-gender aftercare program in Massachusetts for a 2-year follow-up period. This study found that women came to the study in greater need of treatment than men. Women utilized significantly more outpatient treatment services than men. The characteristic of female per se led to more utilization of outpatient services, whereas the baseline characteristics of employed status and alcohol use led to less utilization of outpatient services.
