Feasibility of remote self-collection of dried blood spots, hair, and nails among people with HIV with hazardous alcohol use.

BACKGROUND: The use of biomarkers in behavioral HIV research can help to address limitations of self-reported data. The COVID-19 pandemic forced many researchers to transition from standard in-person data collection to remote data collection. We present data on the feasibility of remote self-collection of dried blood spots (DBS), hair, and nails for the objective assessment of alcohol use, antiretroviral therapy adherence, and stress in a sample of people with HIV (PWH) who are hazardous drinkers. METHODS: Standardized operating procedures for remote self-collection of DBS, hair, and nails were developed for an ongoing pilot study of a transdiagnostic alcohol intervention for PWH. Prior to each study appointment, participants were mailed a kit containing materials for self-collection, instructions, a video link demonstrating the collection process, and a prepaid envelope for returning samples. RESULTS: A total of 133 remote study visits were completed. For DBS and nail collection at baseline, 87.5% and 83.3% of samples, respectively, were received by the research laboratory, of which 100% of samples were processed. Although hair samples were intended to be analyzed, most of the samples (77.7%) were insufficient or the scalp end of the hair was not marked. We, therefore, decided that hair collection was not feasible in the framework of this study. CONCLUSION: An increase in remote self-collection of biospecimens may significantly advance the field of HIV-related research, permitting the collection of specimens without resource-intensive laboratory personnel and facilities. Further research is needed on the factors that impeded participants' ability to complete remote biospecimen collection.

Sexual Assault, Mental Health, and Alcohol Use in College Women: The Role of Resilience and Campus Belonging.

Understanding the mental health outcomes of sexual assault among college women is a public health priority. Although research has identified risk factors for the development of mental health problems following an assault, few studies have utilized a strengths-based approach to identify personal and social resources that may mediate the sexual assault-mental health link. Prior studies allude to the role of resilience and perceived campus belonging in explaining the relationship between sexual assault and mental health. This study represents the first application of the stress process model using a large sample of college women to examine (a) the association between sexual assault and mental health (i.e., psychological distress, suicidality, self-harm) and alcohol use problems and (b) the role of resilience and perceived campus belonging as partial mediators of these associations. Data were collected as part of the Spring 2021 American College Health Association National College Health Assessment (ACHA-NCHA; n = 31,328, Mean age = 20.26, SD = 1.64, 58.8% White), a cross-sectional, online survey that samples college students from 143 self-selected United States colleges. To test our primary hypothesis, a structural regression model was conducted, which included a latent sexual assault predictor, manifest resilience and campus belonging mediators, a latent mental health outcome, and a manifest alcohol use problems outcome. Mental health and alcohol use problems were positively associated with sexual assault and negatively associated with resilience and campus belonging. Resilience partially mediated the association between sexual assault and mental health. Campus belonging partially mediated the association between sexual assault, mental health, and alcohol use problems. This model explained 23.2% of the variance in mental health and 5.9% of the variance in alcohol use. Resilience and campus belonging may represent modifiable factors that can be targeted in trauma-focused interventions in efforts to improve victimized college women's mental health.

Co-occurring Use of Cannabis and Tobacco and the Presence of Acute Respiratory Symptoms among Young Adult Light and Intermittent Smokers.

BACKGROUND: Cannabis use and intermittent smoking are becoming increasingly prevalent among young adults. Thus, identifying health consequences of co-occurring use of these substances represents an emerging research priority. Purpose/Objectives: This study evaluated the relationship between tobacco/cannabis co-use and acute symptoms of respiratory illness among young adult intermittent smokers. We hypothesized that tobacco/cannabis co-use would be more strongly associated with respiratory symptoms relative to use of neither or one product. Methods: A secondary analysis of a three-year observational study was conducted. Non-daily smokers (n = 563) aged 18-24 were recruited via social media and completed electronic surveys at baseline and annually for two years, producing three total assessments. Past-two-week use of tobacco and cannabis was measured at each assessment, as was severity of six acute respiratory symptoms. The respiratory measure was dichotomized to indicate the presence or absence of symptoms. Results: Tobacco/cannabis co-use decreased from 54.8% at baseline to 43.4% at year two (p < .001). Mean respiratory symptoms also declined significantly over time (ps < .05). At each timepoint, co-use was more strongly associated with presence of respiratory symptoms than the use of neither product (aORs = 2.73-4.39, ps ≤ .013). Co-users were also 38%-183% more likely to endorse the presence of respiratory symptoms than single product users at each timepoint (aORs = 1.38-2.83, ps = .023-.212). Conclusions/Importance: Although co-occurring use of tobacco and cannabis by young adults may represent experimental use of multiple substances, it may also promote or exacerbate acute symptoms of respiratory illness. Further exploration with more granular patterns of co-use and across different routes of administration is warranted.

Expectancies and reasons for use of e-cigarettes among young adults: A longitudinal analysis.

Use of electronic cigarettes, or e-cigarettes, has increased exponentially in recent years. Mechanisms that might underlie this increase include expectancies and reasons for e-cigarette use. This study was designed to identify and evaluate changes in expectancies and reasons for e-cigarette use among young adults over time and to determine whether such changes were associated with changes in e-cigarette use. Data for these analyses were collected from a sample of 137 young adult e-cigarette users who completed electronic surveys 5 times over a 12-month period. Results yielded five e-cigarette use expectancy and reason factors: Affect-Related Reasons, Social Reasons, Positive Social Expectancies, Positive Internal Expectancies, and Negative Expectancies. Linear mixed models showed that Negative Expectancies significantly increased over time (p = .004), whereas Affect-Related Reasons significantly decreased over time (p = .001). Additional linear mixed models indicated that, whereas both frequency and quantity of e-cigarette use decreased over time, changes in Positive Internal Expectancies were positively associated with changes in frequency of e-cigarette use (p = .032) and changes in Positive Social Expectancies were positively associated with changes in both frequency (p = .007) and quantity (p = .026) of e-cigarette use. These findings suggest that young adults' expectancies and reasons for using e-cigarettes fluctuate over time, and changes in expectancies seem to be longitudinally associated with changes in e-cigarette use. Positive expectancies for e-cigarette use represent targets for clinical, prevention, and intervention efforts. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The relationship between family history of tobacco use and progression to tobacco use among young adult e-cigarette users.

Family history of tobacco use and use of e-cigarettes have both been associated with increased tobacco use among young adults. However, to our knowledge, these variables have not been considered simultaneously. This study was designed to evaluate the hypothesis that family history of tobacco use would predict tobacco product use over time among young adult e-cigarette users with limited combustible tobacco use experience. A sample of 124 participants were recruited online from across the United States, completed five surveys over 12 months, and reported use of nicotine and tobacco products over the previous two weeks at each survey. Family history of nicotine and tobacco use was reported at the 6-month assessment, and data were collected in 2017 and 2018. Regression models indicated that family history was associated with likelihood of cigarette use (odds ratio = 1.02 [95% confidence interval = [1.00, 1.04]). Significant interactions between family history and linear (OR = 1.05 [1.01, 1.10]) and quadratic (OR = 0.99 (0.98, 1.00)] time terms indicated that the association between family history and likelihood of combustible product use shifted over time. In both cases, more extensive family histories predicted greater use frequency, and follow-up analyses showed that more extensive family history was associated with greater combustible tobacco product use 3, 6, and 9 months following baseline. Family history of nicotine/tobacco use may promote initiation of tobacco use among e-cigarette users. These results suggest family history of tobacco use may comprise a risk factor for combustible tobacco use within the evolving tobacco product landscape.
