Long-term Patterns of Self-reported Opioid Use, VACS Index, and Mortality Among People with HIV Engaged in Care.

Longitudinal analyses of opioid use and overall disease severity among people with HIV (PWH) are lacking. We used joint-trajectory and Cox proportional hazard modeling to examine the relationship between self-reported opioid use and the Veterans Aging Cohort Study (VACS) Index 2.0, a validated measure of disease severity and mortality, among PWH engaged in care. Using data from 2002 and 2018, trajectory modeling classified 20% of 3658 PWH in low (i.e., lower risk of mortality), 40% in moderate, 28% in high, and 12% in extremely high VACS Index trajectories. Compared to those with moderate VACS Index trajectory, PWH with an extremely high trajectory were more likely to have high, then de-escalating opioid use (adjusted odds ratio [AOR], 95% confidence interval [CI] 5·17 [3·19-8·37]) versus stable, infrequent use. PWH who report high frequency opioid use have increased disease severity and mortality risk over time, even when frequency of opioid use de-escalates

Trajectories of Self-Reported Opioid Use Among Patients With HIV Engaged in Care: Results From a National Cohort Study.

BACKGROUND: No prior studies have characterized long-term patterns of opioid use regardless of source or reason for use among patients with HIV (PWH). We sought to identify trajectories of self-reported opioid use and their correlates among a national sample of PWH engaged in care. SETTING: Veterans Aging Cohort Study, a prospective cohort including PWH receiving care at 8 US Veterans Health Administration (VA) sites. METHODS: Between 2002 and 2018, we assessed past year opioid use frequency based on self-reported "prescription painkillers" and/or heroin use at baseline and follow-up. We used group-based trajectory models to identify opioid use trajectories and multinomial logistic regression to determine baseline factors independently associated with escalating opioid use compared to stable, infrequent use. RESULTS: Among 3702 PWH, we identified 4 opioid use trajectories: (1) no lifetime use (25%); (2) stable, infrequent use (58%); (3) escalating use (7%); and (4) de-escalating use (11%). In bivariate analysis, anxiety; pain interference; prescribed opioids, benzodiazepines and gabapentinoids; and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use. In multivariable analysis, illness severity, pain interference, receipt of prescribed benzodiazepine medications, and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use. CONCLUSION: Among PWH engaged in VA care, 1 in 15 reported escalating opioid use. Future research is needed to understand the impact of psychoactive medications and marijuana use on opioid use and whether enhanced uptake of evidence-based treatment of pain and psychiatric symptoms can prevent escalating use among PWH

Accounting for historical injustices in mathematical models of infectious disease transmission: An analytic overview

Differences in infectious disease risk, acquisition, and severity arise from intersectional systems of oppression and resulting historical injustices that shape individual behavior and circumstance. We define historical injustices as distinct events and policies that arise out of intersectional systems of oppression. We view historical injustices as a medium through which structural forces affect health both directly and indirectly, and are thus important to study in the context of infectious disease disparities. In this critical analysis we aim to highlight the importance of incorporating historical injustices into mathematical models of infectious disease transmission and provide context on the methodologies to do so. We offer two illustrations of elements of model building (i.e., parameterization, validation and calibration) that can allow for a better understanding of health disparities in infectious disease outcomes. Mathematical models that do not recognize the historical forces that underlie infectious disease dynamics inevitably lead to the individualization of our focus and the recommendation of untenable individual-behavioral prescriptions to address the burden of infectious disease

Sexual Minority, Justice-Involved Youth: A Hidden Population in Need of Integrated Mental Health, Substance Use, and Sexual Health Services

PurposeWe sought to compare the demographic characteristics, drug and alcohol use, sexual behaviors, delinquency, and mental health indicators of sexual minority and nonsexual minority first-time offending, court-involved, nonincarcerated adolescents.MethodsUsing adolescent- and caregiver-reported baseline data from the Epidemiologic Study Involving Children in the Court, a prospective cohort study of 423 adolescent-caregiver dyads recruited from a Northeastern family court system, we compared demographic and behavioral health characteristics of sexual minority and nonsexual minority first-time offending, court-involved, nonincarcerated adolescents.ResultsNearly one-third of the adolescents (31.4%, n = 133) were classified as a sexual minority; 19.6% (n = 81) self-identified with a nonheterosexual sexual orientation. Sexual minority adolescents were more likely than their nonsexual minority peers to identify as female, to have used psychiatric services or psychotropic medications, to have used an illicit drug or alcohol or to know peers who use these substances, to report alcohol/drug use during sex, to endorse more severe mental health problems, to have more recent post-traumatic symptoms, and to have engaged in self-harm behaviors. However, sexual minority adolescents did not differ from nonsexual minority adolescents in other demographic characteristics (including school performance) or delinquent behavior.ConclusionsOne-third of court-involved, nonincarcerated adolescents may be sexual minorities. Specificscreening methods are necessary to identify these adolescents and to address their unique risk characteristics, which include more severe mental health difficulties and higher rates of high-risk sexual behavior and drug/alcohol use compared with their nonsexual minority peers

Difficulty accessing syringes mediates the relationship between methamphetamine use and syringe sharing among young injection drug users.

Injection drug users (IDU) who use methamphetamine (MA) are at an increased risk of HIV infection due to engagement in injection-related risk behavior including syringe sharing. In this cohort study of young IDU aged 18-30, we investigated the relationship between injection MA use and syringe sharing, and whether difficulty accessing sterile syringes mediated this association. Behavioral questionnaires were completed by 384 IDU in Vancouver, Canada between October 2005 and May 2008. Generalized estimating equations were used to estimate direct and indirect effects. The median age of participants was 24 (IQR: 22-27) and 214 (55.7%) were male. Injecting MA was independently associated with syringe sharing. Mediation analyses revealed that difficulty accessing sterile syringes partially mediated the association between injecting MA and syringe sharing. Interventions to reduce syringe sharing among young methamphetamine injectors must address social and structural barriers to accessing HIV prevention programs

Latinx Youth in First Contact with the Justice System: Trauma and Associated Behavioral Health Needs

This study examines the prevalence of trauma exposure and its association with psychiatric symptoms, substance use, and sexual activity among First-Time Offending, Court-Involved Non-Incarcerated (FTO-CINI) Latinx youth. Latinx youth (N = 181), ages 12-18, were recruited from a family court in the Northeastern region of the United States as part of a longitudinal cohort study of 423 FTO-CINI youth. Baseline data on trauma exposure and symptoms, psychiatric symptoms, substance use (alcohol/marijuana), and sexual activity among the Latinx sample were analyzed by age, gender, and offense type (status versus delinquent). Almost three-quarters of Latinx FTO-CINI youth reported lifetime trauma exposure. Almost half of Latinx youth reported lifetime marijuana use, 30% reported lifetime alcohol use, and 33% reported lifetime sexual activity. Females reported higher rates of internalizing symptoms and greater affect dysregulation. Trauma-exposed youth were more likely than their non-exposed peers to have reported more externalizing symptoms; trauma-exposed females compared to trauma-exposed males reported more severe internalizing symptoms. Latinx FTO-CINI females may have different behavioral health needs than their male counterparts. Court-based screening and assessment practices should attend to the specific behavioral needs of this unique, underserved population

Cannabis Use Among Court-Involved Minority Sexual Orientation and Gender Identity Adolescents.

We examined the effects of family functioning and beliefs regarding peers' cannabis use among minority (n = 112) and non-minority (n = 275) sexual orientation and gender identity (SOGI), first-time court-involved adolescents. We examined longitudinally the effects of baseline general family functioning and peer cannabis use beliefs on self-reported cannabis use and cannabis-related consequences after 12 months. At baseline, 39.2 percent of adolescents reported using cannabis. Minority SOGI adolescents reported worse family functioning (p = .017) and higher peer cannabis use beliefs (p = .047). Higher peer cannabis use beliefs at baseline predicted recent cannabis use at the 12-month assessment for both minority and non-minority SOGI adolescents. Better family functioning predicted a lower likelihood of recent cannabis use at 12 months for non-minority SOGI adolescents, but not for minority SOGI adolescents. Baseline peer cannabis use beliefs and family functioning predicted cannabis-related consequences for both cohorts at 12 months when accounting for intermediate (i.e., four-month and eight-month) data. Among all first-time court-involved adolescents, those who believed greater cannabis use among their peers reported more subsequent cannabis use themselves. Conversely, higher general family functioning may be less of a protective factor for minority SOGI adolescents. These results suggest the utility of feedback interventions to modify peer norm beliefs among first-time court-involved adolescents
