The Effects of E-Cigarette Use on Alcohol and Marijuana Abuse Symptoms in an Ethnically Diverse Sample of Young Adults

Background: We examined e-cigarette use as a prospective predictor of alcohol and marijuana abuse symptoms in a sample consisting of Native Hawaiian and Other Pacific Islander (NHPI), Filipino, Asian (i.e., Japanese, Chinese, Korean), and White young adults. NHPI represent a highly vulnerable group with regard to substance use and are severely understudied. Methods: Data were collected from 1463 young adults (M age = 22.2, SD = 3.2; 59.5% women) enrolled across community colleges in Hawai‘i at two time-points six months apart. Results: Higher frequency of e-cigarette use at baseline was predictive of higher alcohol (B = 0.06, SE = 0.02, p < 0.01) and marijuana (B = 0.06, SE = 0.02, p < 0.01) use problems at six-month follow up, adjusting for baseline cigarette smoking, problem alcohol/marijuana use, sensation seeking, and demographic variables. Ethnicity was found to significantly moderate the relationship between baseline e-cigarette use and problem marijuana use later, such that White and NHPI ethnicities were particularly vulnerable to the effects of e-cigarette use on problem marijuana use. Conclusion: NHPI are often combined with Asians in national surveys, which obfuscates the higher risks faced by NHPI compared with groups that are routinely classified as Asians (e.g., Chinese, Japanese, Filipinos). The current research highlights the NHPI’s vulnerability in terms of the effects of e-cigarette use on marijuana and alcohol abuse symptoms.

A trait-like propensity to experience internalizing symptoms is associated with problem alcohol involvement across adulthood, but not adolescence

There are stable between-person differences in an internalizing “trait,” or the propensity to experience symptoms of internalizing disorders, such as social anxiety, generalized anxiety disorder, and depression. Trait internalizing may serve as a marker of heightened risk for problem alcohol outcomes (such as heavier drinking, binge drinking or alcohol dependence). However, prior research on the association between internalizing symptoms and alcohol outcomes has been largely mixed in adolescence, with more consistent support for an association during adulthood. It may be that trait internalizing is only associated with problem alcohol outcomes in adulthood, after individuals have gained experience with alcohol. Some evidence suggested that these effects may be stronger for females than males. We used data from a community sample (n = 790) interviewed during adolescence (ages 14 – 16) and again at ages 21, 24, 27, 30, 33, and 39. Using generalized estimating equations, we tested the association between trait internalizing and alcohol outcomes during both adolescence and adulthood, and tested whether adult trait internalizing mediated the association between adolescent trait internalizing and adult alcohol outcomes. Trait internalizing in adulthood (but not adolescence) was associated with more frequent alcohol use, binge drinking and symptoms of alcohol use disorders, and mediated the effects of adolescent trait internalizing on alcohol outcomes. We observed no moderation by gender or change in these associations over time. Understanding the developmental pathways of trait internalizing may provide further insights into preventing the emergence of problem alcohol use behavior during adulthood.

Predicting Different Types of Intimate Partner Aggression Perpetration: The Roles of Problem Alcohol Use and Distress Tolerance

Intimate partner aggression (IPA) victimization and substance use have been well established as risk factors for IPA perpetration ( Leonard, 2005 ; Sprunger et al., 2015 ). Recent research has identified a negative association between distress tolerance and physical and psychological IPA perpetration, specifically in males in substance use treatment ( Shorey et al., 2017 ). Research examining the interplay of problem substance use, distress tolerance, and other forms of IPA (i.e., sexual coercion, controlling behaviors) in non-clinical samples is limited. The present analysis aimed to examine the potential moderating effect of distress tolerance on problem alcohol use and four types of IPA perpetration (physical assault, psychological aggression, sexual coercion, and controlling behaviors) in a diverse, national sample ( N = 323; 44.3% female; 52.9% sexual minority; age M = 33.61 years, SD = 8.71). Results showed that alcohol use and distress tolerance had differing influences on each IPA perpetration type. In line with hypotheses, distress tolerance significantly moderated the relationship between problem alcohol use and two forms of IPA (physical assault and controlling behaviors); this relationship was stronger for individuals with low levels of distress tolerance. Significant interaction effects did not emerge for psychological aggression or sexual coercion. Findings suggest that treatment strategies that focus specifically on increasing distress tolerance may be effective in reducing alcohol-facilitated IPA perpetration involving physical assault and controlling behaviors.

Factors associated with syphilis seroprevalence in women with and at-risk for HIV infection in the Women’s Interagency HIV Study (1994–2015)

ObjectiveSyphilis rates among women in the USA more than doubled between 2014 and 2018. We sought to identify correlates of syphilis among women enrolled in the Women’s Interagency HIV Study (WIHS) to inform targeted interventions.MethodsThe retrospective cross-sectional analysis of secondary data included women with HIV or at-risk of HIV who enrolled in the multisite US WIHS cohort between 1994 and 2015. Syphilis screening was performed at baseline. Infection was defined serologically by a positive rapid plasma reagin test with confirmatory treponemal antibodies. Sociodemographic and behavioural characteristics stratified by baseline syphilis status were compared for women enrolled during early (1994–2002) and recent (2011–2015) years. Multivariable binomial modelling with backward selection (p>0.2 for removal) was used to model correlates of syphilis.ResultsThe study included 3692 women in the early cohort and 1182 women in the recent cohort. Syphilis prevalence at enrolment was 7.5% and 3.7% in each cohort, respectively (p<0.01). In adjusted models for the early cohort, factors associated with syphilis included age, black race, low income, hepatitis C seropositivity, drug use, HIV infection and >100 lifetime sex partners (all p<0.05). In the recent cohort, age (adjusted prevalence OR (aPOR) 0.2, 95% CI 0.1 to 0.6 for 30–39 years; aPOR 0.5, 95% CI 0.2 to 1.0 for 40–49 years vs ≥50 years), hepatitis C seropositivity (aPOR 2.1, 95% CI 1.0 to 4.1) and problem alcohol use (aPOR 2.2, 95% CI 1.1 to 4.4) were associated with infection.ConclusionsSyphilis screening is critical for women with HIV and at-risk of HIV. Targeted prevention efforts should focus on women with hepatitis C and problem alcohol use.
