Enhancing gender and ethnic representativeness of NCHA-II data with survey weights: The examples of substance use prevalence and state marijuana legalization

Serious psychological distress and higher associations with tobacco and cannabis use among college students in the United States

OBJECTIVE

To examine associations between serious psychological distress (SPD) and tobacco and cannabis use among college students in the United States.

METHODS

This cross-sectional study included 257,626 college students from the 2019-2022 National College Health Assessment survey. SPD was defined as having symptoms in the past month. Current tobacco (i.e., cigarettes, e-cigarettes) and cannabis use was defined as past month use. Multiple product use was categorized for single, dual, or triple products. Adjusted logistic regression models were used to examine associations between SPD, tobacco, cannabis, and multiple product use.

RESULTS

SPD increased over time (18.4% to 23.8%) among students and nearly 30% of tobacco or cannabis users reported SPD. Cigarette, e-cigarette, or cannabis use was associated with about a 50-60% increased likelihood of reporting SPD than non-current use of each product, with the highest associations in Fall 2020. Triple product users had double the likelihood of reporting SPD, followed by dual users at 70% and single users at 47%, relative to non-current users. Daily users also had nearly twice the likelihood of reporting SPD, followed by non-daily users at 13-35%, relative to non-current users.

CONCLUSIONS

College students have an increasing burden of SPD which is significantly associated with tobacco and cannabis use. There is a dose-response relationship between the number of tobacco and cannabis products used, as well as the frequency of use, and SPD among U.S. college students. Colleges addressing student mental health should prioritize the implementation of screening and treatment support for tobacco, cannabis, and multiple product use.

Autism and sexual and gender minority identity in college students: Examination of self-reported rates, functional outcomes, and treatment engagement

LAY ABSTRACT

Autistic individuals and those who identify with a sexual and/or gender minority are both at risk for various mental health concerns and related impairments. However, the connection between autism and sexual and/or gender minorities and mental health and functional outcomes is not clear. Here, we provide evidence of these connections by analyzing data from a large nationally representative dataset from the American College Health Association-National College Health Assessment III. We found that autistic college students who identify with both sexual and gender minorities reported the highest rates of stress, academic, and mental health concerns including suicidality when compared with autistic college students with or without a sexual and/or gender minority. In addition, college students with at least two identities, such as autism and a sexual minority identity or both a sexual and gender minority identity, reported the next highest rates of concern. These findings affirm the need for mental healthcare providers to consider the intersections of a sexual and gender minority identities in non-autistic and, especially, in autistic college students to develop and provide better support and resources.

Single use of psychoactive substances and its association with sleep disorders and sleep health in a large US college sample

OBJECTIVE

Estimate the association between single (i.e., exclusive) use of a range of substances and sleep outcomes.

PARTICIPANTS

College students participated in the 2015-2019 American College-Health Association-National College-Health Assessment survey.

METHODS

Multivariable logistic and linear regressions were used.

RESULTS

Single users of sedative, opioid, tobacco, and stimulant drugs were more likely to report a diagnosis of insomnia and other sleep disorder and indicated more days per week of negative sleep health outcomes compared not only to non-users of these substances but also polysubstance users. Single users of alcohol were significantly less likely to report a diagnosis of sleep disorder and indicated having had more days per week of positive sleep health outcomes compared to non-alcohol users and polysubstance users. However, those results are reversed for binge drinking.

CONCLUSIONS

Support of programs addressing behaviors to reduce the high prevalence of psychoactive substance use and sleep disturbances in college youth is needed.

Understanding ADHD in AAPI College Students: Prevalence, Comorbidities, Impairments, and Treatment Utilization

OBJECTIVE

Asian American and Pacific Islander (AAPI) students with ADHD may face increased risk for college maladjustment due to cultural factors and a tendency to delay treatment. This is the first study to examine ADHD prevalence, ADHD-related impairments and comorbidities, and ADHD treatment utilization in AAPI college students.

METHOD

AAPI, White, Hispanic, and Black undergraduates (n = 258,005) from the American College Health Association-National College Health Assessment II survey were included in the study.

RESULTS

AAPI students had lower ADHD prevalence rates than White and Black students, and similar prevalence to Hispanic students. AAPI students with ADHD had significantly higher risk for comorbidities and social and academic impairments, compared to White students with ADHD. Approximately half of AAPI students with ADHD did not utilize treatment despite experiencing psychiatric comorbidities and functional impairments.

CONCLUSION

AAPI college students with ADHD are underutilizing treatment despite elevated psychiatric comorbidities and functional impairment.

Health, safety, and socioeconomic impacts of cannabis liberalization laws: An evidence and gap map

Background

Globally, cannabis laws and regulations are rapidly changing. Countries are increasingly permitting access to cannabis under various decriminalization, medicalization, and legalization laws. With strong economic, public health, and social justice incentives driving these domestic cannabis policy reforms, liberalization trends are bound to continue. However, despite a large and growing body of interdisciplinary research addressing the policy-relevant health, safety, and socioeconomic consequences of cannabis liberalization, there is a lack of robust primary and systematic research that comprehensively investigates the consequences of these reforms.

Objectives

This evidence and gap map (EGM) summarizes the empirical evidence on cannabis liberalization policies. Primary objectives were to develop a conceptual framework linking cannabis liberalization policies to relevant outcomes, descriptively summarize the empirical evidence, and identify areas of evidence concentration and gaps.

Search Methods

We comprehensively searched for eligible English-language empirical studies published across 23 academic databases and 11 gray literature sources through August 2020. Additions to the pool of potentially eligible studies from supplemental sources were made through November 2020.

Selection Criteria

The conceptual framework for this EGM draws upon a legal epidemiological perspective highlighting the causal effects of law and policy on population-level outcomes. Eligible interventions include policies that create or expand access to a legal or decriminalized supply of cannabis: comprehensive medical cannabis laws (MCLs), limited medical cannabidiol laws (CBDLs), recreational cannabis laws (RCLs), industrial hemp laws (IHLs), and decriminalization of cultivations laws (DCLs). Eligible outcomes include intermediate responses (i.e., attitudes/behaviors and markets/environments) and longer-term consequences (health, safety, and socioeconomic outcomes) of these laws.

Data Collection and Analysis

Both dual screening and dual data extraction were performed with third person deconfliction. Primary studies were appraised using the Maryland Scientific Methods Scale and systematic reviews were assessed using AMSTAR 2.

Main Results

The EGM includes 447 studies, comprising 438 primary studies and nine systematic reviews. Most research derives from the United States, with little research from other countries. By far, most cannabis liberalization research focuses on the effects of MCLs and RCLs. Studies targeting other laws-including CBDLs, IHLs, and DCLs-are relatively rare. Of the 113 distinct outcomes we documented, cannabis use was the single most frequently investigated. More than half these outcomes were addressed by three or fewer studies, highlighting substantial evidence gaps in the literature. The systematic evidence base is relatively small, comprising just seven completed reviews on cannabis use (3), opioid-related harms (3), and alcohol-related outcomes (1). Moreover, we have limited confidence in the reviews, as five were appraised as minimal quality and two as low quality.

Authors’ Conclusions

More primary and systematic research is needed to better understand the effects of cannabis liberalization laws on longer-term-and arguably more salient-health, safety, and socioeconomic outcomes. Since most research concerns MCLs and RCLs, there is a critical need for research on the societal impacts of industrial hemp production, medical CBD products, and decriminalized cannabis cultivation. Future research should also prioritize understanding the heterogeneous effects of these laws given differences in specific provisions and implementation across jurisdictions.

Racial and Ethnic Differences in Maternal and Child COVID-19 Vaccination Intent Among Pregnant and Postpartum Women in the USA (April-June 2020): an Application of Health Belief Model

This study investigated racial/ethnic differences in pregnant and postpartum women's intentions to receive the COVID-19 vaccination (maternal COVID-19 vaccination intent) and intentions to vaccinate their children against COVID-19 (child COVID-19 vaccination intent) during the early months of the COVID-19 pandemic (April-June 2020). This study also assessed Health Belief Model constructs to examine their influence on maternal and child COVID-19 vaccination intent by race/ethnicity. This study includes 489 US pregnant and postpartum women (18-49 years) recruited via Prolific Academic to complete a 55-item cross-sectional online survey. Crude and adjusted logistic regression analyses were conducted to determine the associations between race/ethnicity, maternal COVID-19 vaccination intent, and child COVID-19 vaccination intent. Among pregnant women, the odds of maternal COVID-19 vaccination intent (aOR = 2.20, 95% CI: .862, 5.61) and child COVID-19 vaccination intent (aOR = .194, 95% CI: .066, .565) among NH Black women were statistically significantly lower than that of NH White women after adjustment for demographic, health, and health belief model variables. Among postpartum women, although some racial differences in maternal or child COVID-19 vaccination intent were observed, these differences were not statistically significant in unadjusted and adjusted models. The findings have implications for future research and interventions which should adopt a racial health equity lens and identify strategies grounded in institutional trustworthiness and systems perspectives to address racial/ethnic disparities in COVID-19 vaccination intent among pregnant and postpartum women during novel pandemics.

Psychosocial functioning associated with prescription stimulant and opioid misuse versus illicit drug use among college students

Objective: College students' prescription stimulant and opioid misuse (PSM and POM) share psychosocial risks with other substance use. We sought to extend a prior study of these issues. Methods: National College Health Assessment (2015-2016) participants ages 18-24 years (n = 79,336) reporting 12-month PSM (defined as use of a drug not prescribed to them), 30-day other illicit drug use (non-cannabis), both, or neither, were compared on other substance use, psychopathology, academic adjustment, attention deficit hyperactivity disorder, and chronic pain. Models were repeated for POM. Results: Relative to those who only misused the prescription drug, those who used other illicit drugs had lower odds of chronic pain and academic problems, but higher odds on nearly every other outcome especially if they also misused the prescription drug. Conclusions: Findings suggest PSM and POM are on a continuum of risk shared with illicit drug use, but also are linked to outcomes specific to these drugs' perceived medical purposes.

Application of The Consolidated Framework for Implementation Research to inform understanding of barriers and facilitators to the implementation of opioid and naloxone training on college campuses

BACKGROUND

The opioid epidemic in the US continues to worsen. Opioid-only and polysubstance-involved opioid overdose deaths are increasing among adolescents and young adults, who have limited knowledge of opioid overdose prevention, including recognition and response. College campuses have infrastructure to support national-level implementation of evidence-based public health strategies for providing opioid overdose prevention and naloxone training programs among this priority population. However, college campuses are an underutilized, understudied setting for this programming. To address this gap, we conducted research assessing barriers and facilitators to planning and implementing this programming on college campuses.

METHODS

We held 9 focus groups among purposively selected campus stakeholders whose perceptions were important to understand in planning for the dissemination and implementation of opioid overdose prevention and naloxone training. Focus group scripts were informed by The Consolidated Framework for Implementation Research (CFIR) to query about perceptions of opioid and other substance use, opioid and other substance use-related resources, and naloxone administration training. We used a deductive-inductive, iterative approach to thematic analysis.

RESULTS

Themes about implementation barriers included (1) the perception that problematic use of other (non-opioid) substances was more prevalent than opioid use on campus and focus on those substances would be a greater priority on college campuses; (2) student schedules were overwhelmed with academic commitments and extracurricular activities, making delivery of additional training challenging; (3) barriers related to the perceived complexity and decentralization of communication on campus, preventing students from knowing how to access substance use-related resources. Themes about implementation facilitators included (1) framing naloxone training as important in becoming a responsible leader on campus and in the broader community and (2) leveraging existing infrastructure, champions within existing campus groups, and tailored messaging to facilitate participation in naloxone training.

CONCLUSIONS

This is the first study to provide in-depth insights into potential barriers and facilitators to widespread, routine implementation of naloxone/opioid education on undergraduate college campuses. The study captured diverse stakeholder perspectives and was theoretically grounded in CFIR, contributing to the growing literature on the application and refinement of CFIR across diverse community and school contexts.

Comparing National College Health Assessment with other surveys of cannabis use and binge drinking among young adult college students 2008-2018

Objective: We considered the utility of National College Health Assessment (NCHA) data relative to other national data for studying college students' cannabis use and binge drinking, and drug policy effects. Participants: Survey data on 18-22-year old college students were drawn from the 2008-2018 NCHA, National Survey on Drug Use and Health (NSDUH), Monitoring the Future (MTF), and Healthy Minds Study (HMS). Methods: Prevalence estimates were compared across data sources in terms of level and change from 2008-2018 using linear regressions, separately for men and women. Results: Mean prevalence estimates for 30-day cannabis use and 2-week binge drinking, and linear time trends did not differ significantly among NCHA, NSDUH, and MTF. Conclusions: NCHA prevalence estimates are similar to those from NSDUH and MTF, NCHA has unique strengths, and some weaknesses can be offset. Findings support the value of NCHA for studying college students' substance use and effects of drug policy.

Associations between discrimination and adverse mental health symptoms and disorder diagnoses among college students in the United States

BACKGROUND

Mental health disorders are prevalent among college students in the US. Perceived discrimination is a known risk factor for adverse mental health and is widespread on college campuses.

METHODS

We estimated the association between perceived discrimination and mental health among US college students using the American College Health Association-National College Health Assessment (ACHA-NCHA), a large national cross-sectional survey of college students.

RESULTS

7.9% of students reported experiences of discrimination, and that discrimination was more common among minority students. Perceived discrimination was associated with 86 excess cases of students reporting being too depressed to function per 1000 students, and 27 excess cases of students reporting seriously considering suicide per 1000 students. Students who experienced discrimination had a 37% increase in the number of mental health symptoms (IRR 1.37 [95% CI 1.35, 1.39], P < .0001) compared to non-discriminated students, and a 94% increase in the number of mental health diagnoses (IRR 1.94 [95% CI 1.89, 1.99], P < .0001). Discrimination was positively associated with all mental health symptoms and diagnoses. This pattern was largely held across sub-analyses by race/ethnicity, gender, and sexual orientation, but with varying magnitudes.

LIMITATIONS

Inability to distinguish between the forms of discrimination experienced, whether involving gender, sexual orientation, or race/ethnicity.

CONCLUSIONS

Consequences of perceived discrimination are of clinical relevance for healthcare providers in general and mental health providers in particular. This study confirms the association between perceived discrimination and adverse mental health in college students. Efforts to reduce discrimination and bias in college campuses may improve the mental health of students.

Associations between discrimination and substance use among college students in the United States from 2015 to 2019

Discrimination has been associated with adverse health behaviors and outcomes, including substance use. Higher rates of substance use are reported among some marginalized groups, such as lesbian, gay, and bisexual populations, and have been partially attributed to discrimination. This study uses 2015-2019 National College Health Assessment data to determine whether college students reporting discrimination due to sexual orientation, race/ethnicity, gender, or age report greater substance use than their peers who do not report such experiences. Additionally, we assess exploratory questions regarding whether substance choices differ among students who reported facing discrimination. Over time, about 8.0% of students reported experiencing discrimination in the past year. After applying inverse probability treatment weights (IPTWs), exposure to discrimination was associated with an excess of 44 cases of marijuana use per 1000 students, an excess of 39 cases of alcohol use per 1000 students, and an excess of 11 cases of prescription painkiller use per 1000 students. Multivariable logistic regression models with IPTW demonstrated that students who experienced discrimination were more than twice as likely to use inhalants and methamphetamine. These students were also significantly more likely to use other drugs, including opiates, non-prescribed painkillers, marijuana, alcohol, hallucinogens, cocaine, and cigarettes; however, the differences with peers were smaller in magnitude. Students who experienced discrimination did not differ from peers who reported non-prescribed antidepressants use and were significantly less likely to use e-cigarettes and smokeless tobacco. Associations between discrimination and substance use vary by race, gender, sexual orientation, and age. These findings indicate that discrimination has significant associations with many kinds of substance use; however, the magnitude varies by substance type. More institutional efforts to address sources of discrimination affecting college students are needed.

Marijuana use trends among college students in states with and without legalization of recreational use: initial and longer-term changes from 2008 to 2018

BACKGROUND AND AIMS

Young adult college students in the United States are likely to be affected by marijuana liberalization trends. However, changes in students' marijuana use following recreational marijuana legalization (RML) have not been examined in more than one RML state at a time, or beyond 1-2 years post-legalization.

DESIGN

Cross-sectional National College Health Assessment survey administered twice yearly from 2008 to 2018.

SETTING

A total of 587 4-year colleges and universities in 48 US states.

PARTICIPANTS

Undergraduates aged 18-26 years attending college in US states that did (n = 234 669 in seven states) or did not (n = 599 605 in 41 states) enact RML between 2008 and 2018.

MEASUREMENTS

Self-reported marijuana use (past 30 days) and individual and contextual covariates, institution-provided institutional and community covariates and publicly available dates when states enacted RML.

FINDINGS

Adjusting for covariates, state differences and state-specific linear time trends (accounting for pre-RML trends), prevalence of 30-day marijuana use increased more among students exposed to RML [odds ratio (OR) = 1.23, 95% confidence interval (CI) = 1.19-1.28, P < 0.001] than among non-RML state students throughout the same time-period; the results were similar for frequent use (≥ 20 days) (OR = 1.18, 95% CI = 1.10-1.27, P < 0.001). Interaction models supported stronger RML effects among students who were female, residing off-campus and aged 21 years and older; sexual orientation did not moderate RML effects. In the earliest states to enact RML (2012) there were increases in use prevalence in the second through the sixth year post-RML compared to pre-RML. In the second legalization group (2015) there were increases in the first and second year post-RML, and greater increases in the third year. In the later states (2016-17), increases were observed in both years after RML.

CONCLUSIONS

In US states that enacted recreational marijuana legislation from 2012 to 2017 there was evidence for a general trend towards greater increases in marijuana use by college students and differential impact by gender, legal using age and campus residence.

Trends in college students' alcohol, nicotine, prescription opioid and other drug use after recreational marijuana legalization: 2008-2018

BACKGROUND

Young adult college students may be particularly sensitive to recreational marijuana legalization (RML). Although evidence indicates the prevalence of marijuana use among college students increased after states instituted RML, there have been few national studies investigating changes in college students' other substance use post-RML.

METHOD

The cross-sectional National College Health Assessment-II survey was administered twice yearly from 2008 to 2018 at four-year colleges and universities. Participants were 18-26 year old undergraduates attending college in states that did (n = 243,160) or did not (n = 624,342) implement RML by 2018. Outcome variables were self-reported nicotine use, binge drinking, illicit drug use, and misuse of prescription stimulants, sedatives, and opioids. Other variables included individual and contextual covariates, and institution-reported institutional and community covariates. Publicly available information was used to code state RML status at each survey administration.

RESULTS

Accounting for state differences and time trends, RML was associated with decreased binge drinking prevalence among college students age 21 and older [OR (95% CI) = 0.91 (0.87 - 0.95), p < .0001] and increased sedative misuse among minors [OR (95% CI) = 1.20 (1.09 - 1.32), p = .0003]. RML did not disrupt secular trends in other substance use.

CONCLUSIONS

In the context of related research showing national increases in college students' marijuana use prevalence and relative increases following state RML, we observed decreases in binge drinking and increases in sedative use that both depended on age. Findings support some specificity in RML-related changes in substance use trends and the importance of individual factors.
