Interaction Effects of Neighborhood Disadvantage and Individual Social Support on Frequency of Alcohol Use in Youth Living with HIV

Intimate partner violence, depression, hazardous alcohol use, and social support among people with HIV initiating HIV care in Cameroon

Intimate partner violence (IPV) has been associated with poor mental health among people with HIV (PWH) globally. Social support may be a strategy to foster mental health among PWH. Little is known about whether the relationship between IPV and mental health differs by IPV type or level of social support. Interviews were conducted with 426 PWH initiating HIV care in Cameroon. Log binomial regression analyses were used to estimate the association between four types of IPV (controlling behavior and emotional, physical, and sexual IPV) and symptoms of depression or hazardous alcohol use, separately by IPV type and level of social support. Over half (54.8%) of respondents experienced moderate/high levels of controlling behavior, 42.0% experienced emotional IPV, 28.2% experienced physical IPV and 23.7% experienced sexual IPV. Controlling behavior was associated with greater prevalence of depressive symptoms. This relationship did not vary meaningfully by level of social support (low: aPR 2.4 [95% CI 1.2, 4.9]; high: 1.7 [95% CI 1.0, 2.7]). Emotional and physical IPV were associated with greater prevalence of depressive symptoms among those with low social support (emotional IPV: aPR 1.9 [95% CI 1.0, 3.4]; physical IPV: aPR 1.8 [95% CI 1.2, 2.8]), but not among those with high social support (emotional IPV: aPR 1.0 [95% CI 0.7, 1.6]; physical IPV: aPR 1.0 [95% CI 0.6, 1.6]). Controlling behavior, emotional IPV, and physical IPV were associated with a greater prevalence of hazardous alcohol use, with moderately larger effect estimates among those with high compared to low social support. Sexual IPV was not associated with depressive symptoms or hazardous alcohol use. Services to screen and care for people experiencing IPV are urgently needed among PWH in Cameroon. Future research to identify barriers, feasibility, acceptability, and organizational readiness to integrate IPV and mental health services into HIV care settings is needed.

Alcohol use and treatment utilization in a national sample of veterans and nonveterans

BACKGROUND

Research comparing prevalence of alcohol use problems and alcohol treatment utilization between veterans and nonveterans is lacking. Whether predictors of alcohol use problems and alcohol treatment utilization differ in veterans vs. nonveterans is also unclear.

METHODS

Using survey data from national samples of post-9/11 veterans and nonveterans (N = 17,298; 13,451 veterans, 3847 nonveterans), we investigated associations between veteran status and 1) alcohol consumption, 2) need for intensive alcohol treatment, and 3) past-year and lifetime alcohol treatment utilization. We also investigated associations between predictors and these three outcomes in separate models for veterans and nonveterans. Predictors included age, gender, racial/ethnic identity, sexual orientation, marital status, education, health coverage, financial difficulty, social support, adverse childhood experiences (ACEs), and adult sexual trauma.

RESULTS

Population weighted regression models demonstrated that veterans reported modestly higher alcohol consumption than nonveterans, but were not significantly more likely to need intensive alcohol treatment. Veterans and nonveterans did not differ in past-year alcohol treatment utilization, but veterans were 2.8 times more likely to utilize lifetime treatment than nonveterans. We found several differences between veterans and nonveterans in associations between predictors and outcomes. For veterans, being male, having higher financial difficulty, and lower social support were associated with need for intensive treatment, but for nonveterans, only ACEs were associated with need for intensive treatment.

CONCLUSIONS

Veterans may benefit from interventions with social and financial support to reduce alcohol problems. These findings can help to identify veterans and nonveterans who are more likely to need treatment.

Neighborhood Disadvantage and Mental Health: Test of a Parallel Mediation Model through Social Support and Negative Emotionality

According to the life stress model, stressful circumstances occur in the context of social, psychological, and environmental features that can function as either resources or aggravating factors, each of which are associated with well-being. This research was designed to test indirect effects of living in disadvantaged neighborhoods on mental health, through reduced social support and increased negative emotionality. This model was tested with data from a national sample of 1050 adults residing in the United States. Participants completed measures of social support, negative emotionality, depression, loneliness, stress, and alcohol consumption. These scores were merged with data from the 2015 American Community Survey to assess indicators of neighborhood disadvantage at the zip code level. The test of a parallel mediation model with structural equation modeling indicated that neighborhood disadvantage did not have direct effects on either psychological distress or alcohol consumption. However, neighborhood disadvantage was associated with greater negative emotionality, and through negative emotionality, exhibited indirect effects on psychological distress and alcohol consumption. These results are consistent with elements of the life stress model that specify various psychosocial traits as maladaptive in the context of stressful environments.

Self-rated physical health, health-risk behaviors, and disparities: A cross-sectional study of youth in the slums of Kampala, Uganda

Self-rated physical health (SRPH) has been extensively used to assess health status. In this study, we examine how youth living in the slums of Kampala perceive their physical health and the psychosocial correlates of poor health. Cross-sectional data from the 2014 Kampala Youth Survey (N = 1,134) of youth ages 12-18 years was used to conduct the analyses. Chi-square tests and logistic regression analyses were conducted to determine associations between SRPH, demographic and psychosocial characteristics. Overall, 72% of youth rated their health as 'excellent' or 'good.' Poor SRPH was associated with older age and lower education, but not with sex. Also, orphans (OR = 2.03; 95%CI:1.51-2.72), those who lived on the streets (OR=3.09; 95%CI:2.30-4.15), who did not have electricity (OR = 2.83;95%CI:2.12-3.78), who initiated alcohol use early (OR = 2.08; 95%CI:1.47-2.94), who frequently get drunk (OR = 5.67; 95%CI:2.69-11.96), who were HIV positive (OR = 2.18; 95%CI:1.47-3.23), who had been injured due to their drinking (OR = 2.09; 95%CI:1.44-3.03), who thought about hurting themselves (OR = 2.09; 95%CI:1.60-2.73), and those who often felt lonely (OR = 2.54; 95%CI:1.61-4.02) had higher odds of poor SRPH compared to their peers without these characteristics. Poor SRPH may serve as a marker for multiple health-risk behaviors and severe health disparities among youth in vulnerable and resource-limited settings.

Exploring the Association Between Social Support and Hazardous Alcohol Use Among Persons Living with HIV in South Western Uganda

Hazardous alcohol use and psychological distress are common among persons living with HIV (PLWH). In Uganda, HIV prevalence is 6.2% with average pure alcohol consumption per capita of 9.8 L. Social support may mitigate hazardous alcohol use. In a cohort of 443 PLWH, we measured social support using the Duke-UNC functional social support scale and self-reported alcohol consumption using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), augmented by phosphatidylethanol (PEth). We examined the association between low social support and hazardous alcohol use using multiple logistic regression models. 30% had low social support and 44% had hazardous alcohol use (AUDIT-C ≥ 3 for women and ≥ 4 for men and/or PEth ≥ 50 ng/mL). We did not detect an association between low social support and hazardous alcohol use. Social support may play no role or a minimal role in preventing PLWH from hazardous alcohol use.

Early and Late Adolescent Factors that Predict Co-use of Cannabis with Alcohol and Tobacco in Young Adulthood

The changing legal landscape of cannabis in the USA has coincided with changes in how cannabis is used, including its co-use with other substances. This study analyzed 10 years of data from a diverse cohort of youth (N = 2429; 54% Hispanic, 16% Asian, 16% white, 3% black, 10% multiracial) to examine predictors in early and late adolescence of co-use of alcohol with cannabis (AC) and tobacco with cannabis (TC) at age 21. Two forms of co-use were examined: concurrent (use of both substances in past month) and sequential (use of one substance right after the other). Analyses focused on four predictor domains: individual (e.g., resistance self-efficacy), peer (e.g., time spent around peers who use), family (e.g., sibling use), and neighborhood (i.e., perceived alcohol and drug problems in neighborhood). For each co-use combination (AC or TC), we estimated parallel process piecewise latent growth models in a structural equation modeling framework using Mplus v8. The final AC and TC co-use models included all predictor variables from the four domains. Increases in positive expectancies and time spent around peers who use AC, as well as steeper decreases in resistance self-efficacy, were all related to a greater likelihood of AC co-use in young adulthood. Increases in sibling TC use and time spent around peers who use TC, as well as steeper decreases in resistance self-efficacy, were all related to a greater likelihood of TC co-use in young adulthood. Overall, findings highlight the importance of addressing peer influence in prevention programming during both early and late adolescence.

Diseases of Despair and Social Capital: Findings from a Population-Based Survey on Opioid Misuse among Adolescents

Deaths related to opioid overdose have increased substantially in the past few years, raising concerns about how to combat this public health emergency. Objectives: We investigated the association of family, school, and community social capital with opioid misuse in the adolescent population. In addition, we examined if adolescents' depressive symptoms have any mediating effects on opioid misuse. Methods: We used the 2018 National Survey on Drug Use and Health (NSDUH) data, and two substantive models with binary logistic regressions. Three social capital variables were added to the full model with control for sociodemographic and health status variables. A mediation analysis was estimated for family and school social capital, major depressive episodes in the past year, and opioid misuse. Results: We found statistically significant relationships between adolescent opioid misuse and family and school social capital. Adolescents' odds of opioid misuse decreased 10% with each additional family situation where they felt supported. Not knowing students in their grade who drank alcohol or used marijuana/hashish decreased the odds of misusing opioids 42% (p < .01). Experience of depressive episodes acted as a mediator for the social capital effects on adolescents' opioid misuse. Conclusions: Our findings lend support that opioid misuse is associated with despair, and therefore, opioid prevention programs need to incorporate strategies to address mental health issues as well. Our findings also underscore the need for focusing on increasing parental awareness and involvement as well as scaling up prevention efforts in high schools where substance abuse is relatively higher.

An inverse relationship between perceived social support and substance use frequency in socially stigmatized populations

INTRODUCTION

Social isolation and alcohol and substance use disorders (ASUD) have been identified as global health risks. Social support is protective against developing ASUD and is associated with beneficial addiction treatment outcomes. Socially stigmatized populations are at higher risk of both social isolation and ASUD, and the link between social support and substance use in these populations has been less researched than in general substance-using populations. We hypothesized that perceived social support, as measured by the Social Provisions Scale (SPS), would have an inverse relationship with frequency of substance use, from subsections of the Addiction Severity Index (ASI) that estimate use over the past 30 days and over an individual's lifetime.

METHODS

Using a cross-sectional design, we conducted secondary correlational analyses with pre-existing data to test our hypothesis in two separate samples made up of socially marginalized populations entering ASUD treatment programs. Sample 1: substance-using male prison inmates (n = 72, average age = 30.79) and Sample 2: primary methamphetamine-using men who have sex with men (n = 86, average age = 43.41).

RESULTS

Significant negative correlations were found between SPS and lifetime use of alcohol, tobacco, and cannabis (r s  - 0.27, -0.39, -0.26; p-values 0.04, 0.001, 0.04, respectively) in Sample 1 and 30-day use of methamphetamine (r s  - 0.28; p-value 0.008) in Sample 2.

DISCUSSION

Differences in results between the samples (lifetime vs 30-day use) may reflect psychosocial and contextual differences impacting perceived social support. Our findings provide support for an important link between perceived social support and frequency of substance use in socially stigmatized populations.

Model-Based Methods to Translate Adolescent Medicine Trials Network for HIV/AIDS Interventions Findings Into Policy Recommendations: Rationale and Protocol for a Modeling Core (ATN 161)

Background

The United States Centers for Disease Control and Prevention estimates that approximately 60,000 US youth are living with HIV. US youth living with HIV (YLWH) have poorer outcomes compared with adults, including lower rates of diagnosis, engagement, retention, and virologic suppression. With Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) support, new trials of youth-centered interventions to improve retention in care and medication adherence among YLWH are underway.

Objective

This study aimed to use a computer simulation model, the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Adolescent Model, to evaluate selected ongoing and forthcoming ATN interventions to improve viral load suppression among YLWH and to define the benchmarks for uptake, effectiveness, durability of effect, and cost that will make these interventions clinically beneficial and cost-effective.

Methods

This protocol, ATN 161, establishes the ATN Modeling Core. The Modeling Core leverages extensive data—already collected by successfully completed National Institutes of Health–supported studies—to develop novel approaches for modeling critical components of HIV disease and care in YLWH. As new data emerge from ongoing ATN trials during the award period about the effectiveness of novel interventions, the CEPAC-Adolescent simulation model will serve as a flexible tool to project their long-term clinical impact and cost-effectiveness. The Modeling Core will derive model input parameters and create a model structure that reflects key aspects of HIV acquisition, progression, and treatment in YLWH. The ATN Modeling Core Steering Committee, with guidance from ATN leadership and scientific experts, will select and prioritize specific model-based analyses as well as provide feedback on derivation of model input parameters and model assumptions. Project-specific teams will help frame research questions for model-based analyses as well as provide feedback regarding project-specific inputs, results, sensitivity analyses, and policy conclusions.

Results

This project was funded as of September 2017.

Conclusions

The ATN Modeling Core will provide critical information to guide the scale-up of ATN interventions and the translation of ATN data into policy recommendations for YLWH in the United States.
