The predictive effect of family genetic risk scores as an indirect measure of causal effects of one disorder on another.

BACKGROUND: One potential cause of comorbidity is the direct causal effect of one disorder - A - on risk for subsequent onset of disorder B. Could genetic risk scores be utilized to test for such an effect? If disorder A causally impacts on risk for disorder B, then genetic risk for disorder A should be lower in cases of disorder A with v. without a prior onset of B. METHODS: In all individuals (n = 905 736) born in Sweden from 1980 to 1990, from six psychiatric and drug use disorders (major depression, anxiety disorders, alcohol use disorder, drug use disorder, bipolar disorder, and schizophrenia), we formed 14 pairs of disorders A and B. In these pairs, we compared, using Cox proportional hazards models, the predictive effect of the familial-genetic risk score (FGRS) for disorder B in those who had v. had not had a prior onset of disorder A. RESULTS: In all pairs, the impact of the FGRS for disorder B was significantly stronger in cases without v. with a prior history of disorder A. These effects were similar across sex, stable across levels of FGRS and not likely due to clinician bias. In many of our disorder pairs, previous clinical studies suggest a mechanism for a causal effect of disorder A on B. CONCLUSIONS: Our findings provide indirect evidence that the occurrence of one psychiatric or substance use disorder often has a causal effect on risk for subsequent disorders. This mechanism may substantially contribute to the widespread comorbidity among psychiatric conditions.

Family history of substance problems among African Americans: Associations with drug use, drug use disorder, and prescription drug misuse.

A family history of substance problems is a well-known risk factor for substance use and use disorders; however, much of this research has been conducted in studies with predominantly White subjects. The aim of this study was to examine the associations between family history density of substance problems and drug use, risk for drug use disorder, and prescription drug misuse in a sample of African American adults. Results indicate that family history density of substance problems increased the risk for all drug outcomes in the full sample. However, when subgroup analyses by gender were conducted, family history was not a risk factor among men for prescription drug misuse.

The impact of family-genetic risk scores on social functioning in individuals affected with six major psychiatric and substance use disorders in a Swedish National Sample.

To examine whether the level of genetic risk in psychiatric disorders impacts the social functioning of affected individuals, we examine the relationship between genetic risk factors for major depression (MD), anxiety disorders (AD), bipolar disorder (BD), non-affective psychosis (NAP), alcohol use disorder (AUD), and drug use disorder (DUD) in disordered individuals and five adverse social outcomes: unemployment, residence in areas of social deprivation, social welfare, early retirement, and divorce. We examine all cases with registration for these disorders from 1995 to 2015 in individuals born in Sweden. Genetic risk was assessed by the family genetic risk score (FGRS) and statistical estimates by Cox proportional hazard models. High genetic risk was significantly and modestly associated with poorer social outcomes in 23 of 30 analyses. Overall, genetic risk for MD, AD, AUD, and DUD impacted social functioning more strongly in affected individuals than did genetic risk for BD and NAP. Social welfare had the strongest associations with genetic risk, and residence in areas of high deprivation had the weakest. In individuals suffering from psychiatric and substance use disorders, high levels of genetic risk impact not only clinical features but also diverse measures of social functioning.

Prevalence of Substance Use Disorders in Sickle Cell Disease Compared to Other Chronic Conditions: a Population-Based Study of Black American Adults.

BACKGROUND: Sickle cell disease (SCD) is a heritable chronic health condition characterized by pain symptoms throughout the life course that are routinely treated with opioids. OBJECTIVE: This study examined differences in substance use disorders in Black American adults with SCD compared to those with other chronic conditions or with no chronic conditions. DESIGN: Data from a population-representative sample of Black Americans with SCD, other chronic conditions, and no chronic conditions were obtained from the National Survey of American Life (NSAL) database. Diagnosis of substance use disorder was determined by structured clinical interview. Hierarchical models controlling for covariates (demographics, socioeconomic status, self-rated health, and mood disorders) compared odds of diagnosis between the three groups. PARTICIPANTS: The sample included 4238 African-American and Black Caribbean participants from the NSAL study who were 18 years of age or older. MAIN MEASURES: Measures included age, sex, income, education, marital status, employment, possession of health insurance, health conditions, and substance use disorders diagnosed by structured clinical interview. KEY RESULTS: Controlling for age, sex, and socioeconomic status, there were no differences in odds of a drug use disorder when comparing individuals with SCD to Black adults with other chronic conditions (OR = 1.12; p = 0.804) or no chronic condition (OR = 2.09; p = 0.102). SCD was, however, associated with greater odds of alcohol use disorders when compared to the groups with other chronic conditions (OR = 2.15; p = 0.01) and no chronic conditions (OR = 5.11; p < 0.001). This effect was not better accounted for by socioeconomic status, marital status, self-rated physical health, or the presence of a mood disorder. CONCLUSIONS: SCD was not a risk factor for drug use disorders. Further data will be needed to understand the factors contributing to increased risk of alcohol use disorders in SCD and the role uncontrolled pain symptoms may have in driving substance use.

The moderation of the genetic risk for alcohol and drug use disorders in a Swedish national sample by the genetic aptitude for educational attainment.

BACKGROUND: Does the genetic aptitude for educational attainment (GAEA) moderate the genetic risk for alcohol use disorder (AUD) and drug use disorder (DUD)? METHODS: In the native Swedish population, born 1960-1980 and followed through 2017 (n = 1 862 435), the family genetic risk score (FGRS) for AUD and DUD and GAEA were calculated from, respectively, the educational attainment and risk for AUD and DUD, of 1st through 5th degree relatives from Swedish national registers. Analyses utilized Aalen's linear hazards models. RESULTS: Risk for AUD was robustly predicted by the main effects of FGRSAUD [b = 6.32 (95% CI 6.21-6.43), z = 64.9, p < 0.001) and GAEA [b = -2.90 (2.83-2.97), z = 44.1, p < 0.001] and their interaction [b = -1.93 (1.83-2.03), z = 32.9, p < 0.001]. Results were similar for the prediction of DUD by the main effects of FGRSDUD [b = 4.65 (CI 4.56-4.74), z = 59.4, p < 0.001] and GAEA [-2.08 (2.03-2.13), z = 46.4, p < 0.001] and their interaction [b = -1.58 (1.50-1.66)), z = 30.2, p < 0.001]. The magnitude of the interactions between GAEA and FGRSAUD and FGRSDUD in the prediction of, respectively, AUD and DUD was attenuated only slightly by the addition of educational attainment to the model. CONCLUSIONS AND RELEVANCE: The genetic propensity to high educational attainment robustly moderates the genetic risk for both AUD and DUD such that the impact of the genetic liability to AUD and DUD on the risk of illness is substantially attenuated in those with high v. low GAEA. This effect is not appreciably mediated by the actual level of educational attainment. These naturalistic findings could form the basis of prevention efforts in high-risk youth.

Death of parent, sibling, spouse, and child in a Swedish national sample and risk of subsequent stress reaction, major depression, alcohol-use disorder, and drug-use disorder.

BACKGROUND: To determine, in a general population, how much rates of stress reactions (SR), major depression (MD), alcohol-use disorder (AUD) and drug-use disorder (DUD) increase after the death of close relatives. METHODS: SR, MD, AUD, and DUD registrations were assessed from national Swedish registries. From the population followed from 2000 to 2018, those exposed to death of a close relative in 2002-2016 were matched to unexposed controls and analyzed in males and females by a controlled pre-post design using a difference-in-difference method. RESULTS: Substantial, brief increases in risk for SR and more modest prolonged increases in MD were observed after death of relatives in both men and women greatest with children, followed by spouses, parents, and siblings. Relatively long-lasting modest increases in AUD but not DUD were also observed following death of relatives. The absolute increases for SR and MD were greater in females than males and for AUD greater in males than females. However, logistic regression analyses showed most effects did not differ significantly by sex. Consistently larger increases in disorder risk were seen with the death of younger v. older parents, siblings, and spouses and with accidental v. non-accidental death in children. CONCLUSIONS: Applying a matched cohort design to Swedish population registries, death of close relatives was associated with, and likely caused, substantial increases in rates of SR, MD, and AUD, consistent with smaller prior clinical investigations. Through such registries, we can, in large representative samples, integrate the impact of exposures to selected environmental adversities into disorder risk pathways.

Moral injury and substance use disorders among US combat veterans: results from the 2019-2020 National Health and Resilience in Veterans Study.

BACKGROUND: Exposure to potentially morally injurious events (PMIEs) is associated with increased risk for substance use disorders (SUDs), although population-based studies remain limited. The goal of this study was to better understand the relationships between PMIE exposure and lifetime and past-year alcohol use disorder (AUD), drug use disorder (DUD), and SUD. METHODS: Data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 1321 combat veterans. Multivariable analyses examined associations between three types of PMIE exposure (perpetration, witnessing, and betrayal), and lifetime and past-year AUD, DUD, and SUD, adjusting for sociodemographic variables, combat exposure severity, prior trauma, and lifetime posttraumatic stress disorder and major depressive disorder. RESULTS: Perpetration was associated with increased odds of lifetime AUD (OR 1.15; 95% CI 1.01-1.31) and lifetime SUD (OR 1.18; 95% CI 1.03-1.35). Witnessing was associated with greater odds of past-year DUD (OR 1.20; 95% CI 1.04-1.38) and past-year SUD (OR 1.14; 95% CI 1.02-1.28). Betrayal was associated with past-year AUD (OR 1.20; 95% CI 1.03-1.39). A large proportion of the variance in past-year AUD was accounted for by betrayal (38.7%), while witnessing accounted for 25.8% of the variance in past-year DUD. CONCLUSIONS: Exposure to PMIEs may be a stronger contributor to SUDs among veterans than previously known. These findings highlight the importance of targeted assessment and treatment of moral injury among veterans with SUDs, as well as attending to specific types of morally injurious experiences when conceptualizing and planning care.

Differences in genetic risk score profiles for drug use disorder, major depression, and ADHD as a function of sex, age at onset, recurrence, mode of ascertainment, and treatment.

BACKGROUND: Do genetic risk profiles for drug use disorder (DUD), major depression (MD), and attention-deficit hyperactivity disorder (ADHD) differ substantially as a function of sex, age at onset (AAO), recurrence, mode of ascertainment, and treatment? METHODS: Family genetic risk scores (FGRS) for MD, anxiety disorders, bipolar disorder, schizophrenia, alcohol use disorder, DUD, ADHD, and autism-spectrum disorder were calculated from 1st-5th degree relatives in the Swedish population born 1932-1995 (n = 5 829 952). Profiles of these FGRS were obtained and compared across various subgroups of DUD, MD, and ADHD cases. RESULTS: Differences in FGRS profiles for DUD, MD, and ADHD by sex were modest, but they varied substantially by AAO, recurrence, ascertainment, and treatment with scores typically higher in cases with greater severity (e.g. early AAO, high recurrence, ascertainment in high intensity clinical settings, and treatment). However, severity was not always related to purer genetic profiles, as genetic risk for many disorders often increased together. However, some results, such as by mode of ascertainment from different Swedish registries, produced qualitative differences in FGRS profiles. CONCLUSIONS: Differences in FGRS profiles for DUD, MD, and ADHD varied substantially by AAO, recurrence, ascertainment, and treatment. Replication of psychiatric studies, particularly those examining genetic factors, may be difficult unless cases are matched not only by diagnosis but by important clinical characteristics. Genetic correlations between psychiatric disorders could arise through one disorder impacting on the patterns of ascertainment for the other, rather than from the direct effects of shared genetic liabilities.

Cross-generational transmission of genetic risk for alcohol and drug use disorders: the impact of substance availability on the specificity of genetic risk.

BACKGROUND: Among individuals with alcohol use disorder (AUD) and drug use disorder (DUD), is their genetic liability and its specificity moderated by substance availability? METHODS: Offspring (born 1960-1995) and their biological parents from three family types [not-lived-with (NLW) biological father, mother and adoptive] and their AUD and DUD diagnoses were ascertained from Swedish national registers. Parent-offspring resemblance was calculated by tetrachoric correlation. RESULTS: In Swedes born from 1960 to 1995, prevalence rates of AUD were stable while DUD rates increased substantially. Best-estimate tetrachoric correlations (±95% confidence intervals) between AUD in biological parents and AUD and DUD in their offspring were, respectively, +0.19 (0.18-0.20) and +0.18 (0.17-0.20). Parallel results from DUD in parents to AUD and DUD in children were +0.12 (0.10-0.13) and +0.27 (0.26-0.28). When divided into older and younger cohorts, the specificity of DUD transmission increased substantially over time, while the genetic correlation between AUD and DUD significantly decreased. CONCLUSIONS: Raised when alcohol was the preferred substance of abuse and illicit drugs highly stigmatized, AUD in parents reflected a general liability to substance use disorders, as they transmitted similar genetic risk for AUD and DUD to their children raised when both substances were widely available and relatively acceptable. DUD in parents, by contrast, reflected a more specific liability to DUD and, when transmitted to offspring, produced a considerably stronger risk for DUD than for AUD that increased over time. The magnitude and specificity of the genetic liability to psychoactive substances can be influenced by the availability of that substance.

Shared genetic and environmental etiology between substance use disorders and suicidal behavior.

BACKGROUND: Previous studies have demonstrated substantial associations between substance use disorders (SUD) and suicidal behavior. The current study empirically assesses the extent to which shared genetic and/or environmental factors contribute to associations between alcohol use disorders (AUD) or drug use disorders (DUD) and suicidal behavior, including attempts and death. METHODS: The authors used Swedish national registry data, including medical, pharmacy, criminal, and death registrations, for a large cohort of twins, full siblings, and half siblings (N = 1 314 990) born 1960-1980 and followed through 2017. They conducted twin-sibling modeling of suicide attempt (SA) or suicide death (SD) with AUD and DUD to estimate genetic and environmental correlations between outcomes. Analyses were stratified by sex. RESULTS: Genetic correlations between SA and SUD ranged from rA = 0.60-0.88; corresponding shared environmental correlations were rC = 0.42-0.89 but accounted for little overall variance; and unique environmental correlations were rE = 0.42-0.57. When replacing attempt with SD, genetic and shared environmental correlations with AUD and DUD were comparable (rA = 0.48-0.72, rC = 0.92-1.00), but were attenuated for unique environmental factors (rE = -0.01 to 0.31). CONCLUSIONS: These findings indicate that shared genetic and unique environmental factors contribute to comorbidity of suicidal behavior and SUD, in conjunction with previously reported causal associations. Thus, each outcome should be considered an indicator of risk for the others. Opportunities for joint prevention and intervention, while limited by the polygenic nature of these outcomes, may be feasible considering moderate environmental correlations between SA and SUD.

Spatiotemporal patterns of drug use disorder in Sweden assessed using population-based registries.

BACKGROUND: Drug Use Disorder (DUD) is a major contributor to world-wide morbidity and mortality. The extensive national registers in Sweden provide the basis for a study of spatial and temporal patterns of DUD onset and recurrence in Sweden from 2001-2015. METHODS: To identify patterns of DUD over space, time and gender for Swedish individuals aged 15-35, space-time clustering using SaTScan was applied. We used yearly information on residential locations in Demographic Statistical Areas (DeSO) for all of Sweden. The clustering analysis used a Poisson probability model and a null hypothesis that the expected number of cases in each DeSO was proportional to the population size of DeSOs. As SaTScan results can be unstable, steps were taken to determine stable clusters and to refine and optimize cluster size. Results for each gender-register combination were compared to the results of spatial clustering using Gi* statistics. The space-time scanning model was also run with an adjustment for neighborhood socioeconomic status to determine DUD prevalence as it relates to education, income, unemployment and receipt of social welfare. RESULTS: DUD prevalence increased over time. Males yielded more significant clusters than females for both criminal and medical registers. Female DUD prevalence rates increased over time, especially after 2012. Higher correlations in DUD rates existed across the two registers than across gender. Male clusters were present from 2004 onwards while female-criminal clusters appeared after 2007, and female-medical clusters not until 2010. By 2013, clusters existed for all gender-register combinations. Male-criminal clusters were concentrated in Stockholm, Göteborg and Malmö as were male and female-medical clusters. Neighborhood SES was more highly related to the distribution of criminal than medical DUD clusters. A persistent gap in core clusters was identified in Stockholm in an area with notably high SES. CONCLUSIONS: Persistent hotspots of DUD in Sweden were confirmed as well as new and emerging hotspots, especially in Stockholm, Göteborg and Malmö. Higher correlations existed in DUD rates across registers than across gender. The findings are useful for monitoring the current drug problem and for identifying drivers underlying patterns of spread and important causal pathways to DUD.

Military service and risk of subsequent drug use disorders among Swedish men.

PURPOSE: Environmental factors contribute substantially to risk for drug use disorders (DUD). The current study applies multiple methods to empirically test whether military service is associated with subsequent DUD, as previous findings are inconsistent. METHODS: Longitudinal Swedish national registry data on a cohort of male conscripts born 1972-1987 (maximum N = 485,900) were used to test the association between military service and subsequent registration for DUD. Cox proportional hazard models were used in preliminary analyses, followed by three methods that enable causal inference: propensity score models, co-relative models, and instrumental variable analysis. RESULTS: Across all methods, military service was causally associated with lower risk of DUD. Hazard ratios ranged from HR = 0.43 (95% confidence intervals [CI] 0.37; 0.50) in the instrumental variable analysis to 0.77 (0.75; 0.79) in the multivariate propensity score matching analysis. This effect diminished across time. In the model including a propensity score, HRs remained below 1 across the observation period, while confidence intervals included 1 after ~ 11 years in the co-relative analysis and after ~ 21 years in the instrumental variable analysis. CONCLUSIONS: In this cohort of Swedish men, complementary methods indicate that military service conferred substantial but time-limited protection against subsequent DUD. The observed effect could be due to reduced opportunity for substance use during service, social cohesion experienced during and after service, and/or socioeconomic advantages among veterans. Additional research is necessary to clarify these protective mechanisms and determine how other environmental contexts can provide similar benefits.

Drug-use disorders in the Eastern Mediterranean Region: a glance at GBD 2019 findings.

PURPOSE: The aim of this study is to investigate drug use disorders which are a major cause of Disability Adjusted Life Years (DALYs) in the Eastern Mediterranean Region (EMR). METHODS: This article is a part of the global burden of diseases (GBD), injuries, and risk factors 2019 study. The GBD modeling approach was used to estimate population-level prevalence of drug use disorders. We combined these estimates with disability weights to calculate years of life lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs) for 1990-2019. RESULTS: It is estimated that in 2019 in EMR around 3.4 million people have drug use disorder which has increased by 137% compared to 1990. Also, in 2019, DALY number for drug use disorders was 1217.9 (95% UI: 940.4, 1528.9) thousand years and 7645 (95% UI: 6793.7, 8567.9) deaths occurred. The DALY rate increased 39.6% in the region since1990, whereas the global rate increased by 24.4%. United Arab Emirates, Libya, and Iran were most affected by drug use disorders with the highest rates of age-standardized DALY in EMR in 2019. The most prevalent drug use disorder in the region is opioid use which is accountable for 80% of all drug use disorders DALYs. CONCLUSION: Despite many interventions, drug use disorders are still responsible for high rates of DALY in the region which has increased since 1990 in both males and females; more comprehensive policies, better control measures and proper education could reduce the adverse effects.

Experiences with Eviction, House Foreclosure, and Homelessness Among COVID-19 Infected Adults and Their Relation to Mental Health in a Large U.S. City.

This study examined experiences with eviction, house foreclosures, and homelessness in a large U.S. city sample of adults with Coronavirus Disease-2019 (COVID-19). A total of 3595 adults with COVID-19 participated in an assessment of health and well-being after completing contact tracing activities. The sample had a 5.7% lifetime prevalence of eviction, 3.7% lifetime prevalence of house foreclosure, and 8.2% lifetime prevalence of homelessness. Relative importance analyses revealed drug use was the most important variable associated with any lifetime eviction, lifetime house foreclosure, lifetime homelessness, and being currently at-risk of eviction or recently evicted. Loneliness was also relatively strongly associated with any lifetime eviction or homelessness, while socioeconomic characteristics were the most importance variables associated with late mortgage payments in the past month. Treatment for addiction problems may be important for in the aftermath of the COVID-19 pandemic and adults with histories of housing instability may be particularly at risk.

Childhood social capital and drug use disorder in adulthood: A retrospective study on antecedent determinants of the type of drug use.

Based on a sample of Danish adults who were enroled in treatment for drug use disorders as a prerequisite for qualifying for receiving unemployment benefits, we analyse the relationship between low social capital in childhood (LSCC) and the type of drug use in adulthood. The type of drug use is measured by distinguishing between those who were treated for using hard drugs (e.g., heroin and cocaine) and those who were treated for using soft drugs (cannabis). Extracting data from the initial treatment registration report, social capital is operationalised into seven different LSCC categories, and the total number of LSCC (the LSCC score) is recorded. Based on logistic regressions, the LSCC score shows a strong graded dose-response relationship with hard drug use. With each additional LSCC, the probability of being treated for hard drug use increases with 9%. Parental child abuse is the most important single predictor of being treated for hard drug use. Having been parentally abused as a child raises the probability by 32%. The results hold after controlling for age, initiation age, and number of years of drug use, all of which show a significant reversed U-shaped relationship with hard drug use.

Cognitive Enhancer Donepezil Attenuates Heroin-Seeking Behavior Induced by Cues in Rats.

PURPOSE: Opioid use disorder is a significant global problem. Chronic heroin use is associated with impairment of cognitive function and conscious control ability. The cholinergic system can be disrupted following heroin administration, indicating that activation of the cholinergic system may prevent chronic heroin misuse. Donepezil as an inhibitor of cholinesterase has been reported to clinically improve cognition and attention. In this study, the inhibition of heroin self-administration and heroin-seeking behaviours by donepezil were evaluated in rats. METHODS: Rats were trained to self-administer heroin every four hours for 14 consecutive days under a fixed ratio 1 (FR1) reinforcement schedule, then underwent withdrawal for two weeks. A progressive ratio schedule was then used to evaluate the relative motivational value of heroin reinforcement. After withdrawal, a conditioned cue was introduced for the reinstatement of heroin-seeking behaviour. Donepezil (0.3-3 mg/kg, i.p.) was used during both the FR1 heroin self-administration and progressive ratio schedules. Immunohistochemistry was used to investigate the mechanism of action of donepezil in the rat brain. RESULTS: Pre-treatment with high dose donepezil (3 mg/kg) but not low doses (0.3-1 mg/kg) significantly inhibited heroin self-administration under the FR1 schedule. Donepezil decreased motivation values under the progressive ratio schedule in a dose-dependent manner. All doses of donepezil (1-3 mg/kg) decreased the reinstatement of heroin seeking induced by cues. Correlation analysis indicated that the inhibition of donepezil on heroin-seeking behaviour was positively correlated with an increased expression of dopamine receptor 1 (D1R) and dopamine receptor 2 (D2R) in the nucleus accumbens (NAc) and increased expression of choline acetyltransferase (ChAT) in the ventral tegmental area (VTA). CONCLUSIONS: The present study demonstrated that donepezil could inhibit heroin intake and heroin-seeking behaviour. Further, donepezil could regulate dopamine receptors in the NAc via an increase of acetylcholine. These results suggested that donepezil could be developed as a potential approach for the treatment of heroin misuse.

Examining Differences in Substance Use Outcomes and Related Correlates among Transfeminine and Transmasculine Adults Using the 2017 New York State Patient Characteristics Survey.

Background: Transgender persons in the U.S. experience high levels of violence and discrimination which have been linked to adverse substance use outcomes. Despite transgender women's higher exposure to such deleterious events compared to transgender men, studies have often aggregated both transgender women and men, obfuscating potentially unique differences between these groups. The current study, guided by the Minority Stress Model, examines differences in substance use outcomes and related correlates among transfeminine and transmasculine adults. Methods: A secondary data analysis was conducted using the 2017 Patient Characteristics Survey of public mental health facilities in the state of New York (N = 1387). Controlling for theoretically relevant factors, logistic regression models were estimated to examine differences between transfeminine and transmasculine adults in alcohol-related disorder (ARD) and drug use-related disorder (DURD) diagnoses, and tobacco use. Correlates of substance use disparities were also examined within gender identity groups. Results: Overall, 35% of participants were documented as using tobacco products whereas 14 and 19% were diagnosed with ARDs and DURDs, respectively. Transfeminine participants were 1.44-times more likely to be diagnosed with ARDs relative to transmasculine adults. Compared to transmasculine and White participants, transfeminine and Black participants were 1.64- and 1.59-times more likely to be diagnosed with DURDs. Conclusions: Recognizing the observed higher hazardous substance use risk among transfeminine and Black participants, findings indicate the potential role of minority stress in health outcomes of stigmatized communities. Our findings emphasize the need for identifying prevention and treatment strategies aimed at mitigating the implications of minority stress.

Religious institutions as a link to substance use treatment: Characterizing the potential service population through national survey data.

Background: Relatively few Americans with current alcohol or drug use disorders receive outpatient or residential treatment. Outreach initiatives at local places of religious worship have been proposed as a way of facilitating such service use, but the number and characteristics of adults who may be reached in this way has not been studied. Methods: Data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III, a nationally representative cross-sectional survey of U.S. adults were used to estimate the number of and proportion of adults with substance use disorders (SUDs) who attended monthly religious service and did not receive SUD treatment in the past year and used multinomial logistic regression to compare them to three SUD groups who did or did not receive treatment and/or attend religious services. Results: A total of 5,795 respondents representing 35.8 million Americans met criteria for a past-year SUD, of whom 8.3 million (23.1%) attended religious services monthly and did not receive substance use treatment. This more often African-American group had substantially fewer socio-demographic disadvantages (e.g., unemployment), behavioral problem indicators (e.g., police involvement), a higher quality of life score and less likelihood of an illicit drug use diagnosis than those who received treatment and either did or did not attend religious services. Conclusion: Almost one quarter of adults with a SUD attend religious services monthly and do not receive SUD treatment. Although they have fewer adversities than people who receive treatment, outreach to this population may link this substantial group of people to needed services.Highlights/reviewNational survey data suggest 8 of 36 million Americans with substance use diagnoses' (23%) do not receive specialized SUD treatment, but they do attend religious services monthly or more.This group, notably, has less numerous problems, such as unemployment, police involvement, and drug use disorder, and have higher quality of life scores than those who receive treatment for SUD.Outreach and linkage initiatives with religious institutions may facilitate use of services by this population.

Associations Between Lifetime Panic Attacks, Posttraumatic Stress Disorder, and Substance Use Disorders in a Nationally Representative Sample.

Objective: Rates of lifetime substance use disorder (SUD) are high among people with lifetime posttraumatic stress disorder (PTSD). Panic attacks are also prevalent among trauma survivors and people with SUD, yet studies on PTSD/SUD have rarely examined comorbid panic. This potentially creates additional barriers to effective treatment for people with PTSD/SUD, in that panic may be under-diagnosed among people with PTSD/SUD and consequently attenuate treatment outcome. Additionally, research on PTSD/SUD often combines people with alcohol use disorder (AUD) and people with drug use disorders (DUDs) into a single group despite evidence that these two PTSD/SUD subgroups differ along important sociodemographic and clinical variables. This study tested the hypothesis that among adults with lifetime PTSD, panic attacks would be associated with greater lifetime risk for both AUD and DUD. We also explored whether panic attacks were associated with specific DUDs that frequently co-occur with PTSD (cannabis, sedatives/tranquilizers, heroin/opioids, and cocaine). Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III), a cross-sectional national study. Adults with lifetime PTSD (N = 2,230) were classified into one of three groups based on diagnostic interview data: adults with PTSD/AUD (i.e., met criteria for PTSD and AUD but not DUD; n = 656), adults with PTSD/DUD (i.e., met criteria for PTSD and DUD, regardless of AUD diagnostic status; n = 643), or adults with PTSD-only (i.e., met criteria for PTSD but not AUD or DUD; n = 1,031). Results: Weighted logistic regression analyses showed that lifetime risk of PTSD/AUD and PTSD/DUD, each relative to PTSD-only, was greater for adults who were younger at the time of data collection, were male, and had a history of panic attacks. Panic attacks did not predict specific DUD diagnoses comorbid with PTSD in exploratory analyses adjusting for sociodemographic and clinical covariates. Conclusions: Findings highlight the importance of assessing and targeting panic in PTSD/SUD clinics, but suggest panic may not discriminate between specific DUDs that commonly co-occur with PTSD. Study limitations and future directions are discussed.

Methadone and buprenorphine discontinuation among postpartum women with opioid use disorder.

BACKGROUND: The postpartum year is a vulnerable period for women with opioid use disorder, with increased rates of fatal and nonfatal overdose; however, data on the continuation of medications for opioid use disorder on a population level are limited. OBJECTIVE: This study aimed to examine the effect of discontinuing methadone and buprenorphine in women with opioid use disorder in the year following delivery and determine the extent to which maternal and infant characteristics are associated with time to discontinuation of medications for opioid use disorder. STUDY DESIGN: This population-based retrospective cohort study used linked administrative data of 211,096 deliveries in Massachusetts between 2011 and 2014 to examine the adherence to medications for opioid use disorder. Individuals receiving medications for opioid use disorder after delivery were included in the study. Here, demographic, psychosocial, prenatal, and delivery characteristics are described. Kaplan-Meier survival analysis and Cox regression modeling were used to examine factors associated with medication discontinuation. RESULTS: A total of 2314 women who received medications for opioid use disorder at delivery were included in our study. Overall, 1484 women (64.1%) continued receiving medications for opioid use disorder for a full 12 months following delivery. The rate of continued medication use varied from 34% if women started on medications for opioid use disorder the month before delivery to 80% if the medications were used throughout pregnancy. Kaplan-Meier survival curves differed by maternal race and ethnicity (the 12-month continuation probability was .65 for White non-Hispanic women and .51 for non-White women; P<.001) and duration of use of prenatal medications for opioid use disorder (12-month continuation probability was .78 for women with full prenatal engagement and .60 and .44 for those receiving medications for opioid use disorder ≥5 months [but not throughout pregnancy] and ≤4 months prenatally, respectively; P<.001). In all multivariable models, duration of receipt of prenatal medications for opioid use disorder (≤4 months vs throughout pregnancy: adjusted hazard ratio, 3.26; 95% confidence interval, 2.72-3.91) and incarceration (incarceration during pregnancy or after delivery vs none: adjusted hazard ratio, 1.79; 95% confidence interval, 1.52-2.12) were most strongly associated with the discontinuation of medications for opioid use disorder. CONCLUSION: Almost two-thirds of women with opioid use disorder continued using medications for opioid use disorder for a full year after delivery; however, the rates of medication continuation varied significantly by race and ethnicity, degree of use of prenatal medications for opioid use disorder, and incarceration status. Prioritizing medication continuation across the perinatal continuum, enhancing sex-specific and family-friendly recovery supports, and expanding access to medications for opioid use disorder despite being incarcerated can help improve postpartum medication adherence.
