Sequencing hour-level temporal patterns of polysubstance use among persons who use cocaine, alcohol, and cannabis: A back-translational approach

BACKGROUND

Polysubstance use is highly prevalent among persons who use cocaine; however, little is known about how alcohol and cannabis are used with cocaine. We identified temporal patterns of cocaine+alcohol and cocaine+cannabis polysubstance use to inform more translationally relevant preclinical models.

METHODS

Participants who used cocaine plus alcohol and/or cannabis at least once in the past 30 days (n=148) were interviewed using the computerized Substance Abuse Module and the newer Polysubstance Use-Temporal Patterns Section. For each day in the past 30 days, participants reported whether they had used cocaine, alcohol, and cannabis; if any combinations of use were endorsed, participants described detailed hourly use of each substance on the most "typical day" for the combination. Sequence analysis and hierarchical clustering were applied to identify patterns of timing of drug intake on typical days of cocaine polysubstance use.

RESULTS

We identified five temporal patterns among the 180 sequences of reported cocaine polysubstance use: 1) limited cocaine/cocaine+alcohol use (53%); 2) extensive cannabis then cocaine+alcohol+cannabis use (22%); 3) limited alcohol/cannabis then cocaine+alcohol use (13%); 4) extensive cocaine+cannabis then cocaine+alcohol+cannabis use (4%); and 5) extensive cocaine then cocaine+alcohol use (8%). While drug intake patterns differed, prevalence of use disorders did not.

CONCLUSIONS

Patterns were characterized by cocaine, alcohol, and cannabis polysubstance use and by the timing, order, duration, and quantity of episode-level substance use. The identification of real-world patterns of cocaine polysubstance use represents an important step toward developing laboratory models that accurately reflect human behavior.

The HealthStreet Cancer Survivor Cohort: a Community Registry for Cancer Research

PURPOSE

This report describes a cancer survivor cohort from a community engagement program and compares characteristics and willingness to participate in health research between the cancer survivors and non-cancer community members.

METHODS

Among 11,857 members enrolled in HealthStreet at the University of Florida (10/2011-03/2020), 991 cancer survivors were identified and 1:1 matched to control members without cancer on sex, age, and zip code. Demographics, body weight, height, social determinants of health, history of cancer, and willingness to participate in research were recorded by Community Health Workers as a part of the baseline Health Needs Assessment.

RESULTS

Among the cancer survivors, 71.6% were female and 19.2% lived in rural areas with a mean age of 56.7 years in females and 60.8 years in males. At baseline, 44.7% received a cancer diagnosis within 5 years, while 15.8%, more than 20 years. Cancer survivors (vs. matched non-cancer controls) were less likely to be Black (31.1% vs. 63.6%) but more likely to be divorced, separated, or widowed (49.5% vs. 41.2%), be normal/underweight (34.0% vs. 25.6%) and have health insurance (80.0% vs. 68.6%; all p < 0.05). Cancer survivors versus matched controls reported higher rates of ever being in a health research study (32.4% vs. 24.9%) and interest in participating in studies ranging from minimal risk to greater-than-minimal risk.

CONCLUSIONS

Cancer survivors from this community engagement program agnostic to cancer types and treatment are diverse in geography, race, and social determinants of health and can be a valuable resource for observational, interventional, and biospecimen research in cancer survivorship.

Evaluation of an online research best practices training for community health workers and promotoras

Introduction

Community health workers and promotoras (CHW/Ps) have a fundamental role in facilitating research with communities. However, no national standard training exists as part of the CHW/P job role. We developed and evaluated a culturally- and linguistically tailored online research best practices course for CHW/Ps to meet this gap.

Methods

After the research best practices course was developed, we advertised the opportunity to CHW/Ps nationwide to complete the training online in English or Spanish. Following course completion, CHW/Ps received an online survey to rate their skills in community-engaged research and their perceptions of the course using Likert scales of agreement. A qualitative content analysis was conducted on open-ended response data.

Results

104 CHW/Ps completed the English or Spanish course (n = 52 for each language; mean age 42 years SD ± 12); 88% of individuals identified as female and 56% identified as Hispanic, Latino, or Spaniard. 96%-100% of respondents reported improvement in various skills. Nearly all CHW/Ps (97%) agreed the course was relevant to their work, and 96% felt the training was useful. Qualitative themes related to working more effectively as a result of training included enhanced skills, increased resources, and building bridges between communities and researchers.

Discussion

The CHW/P research best practices course was rated as useful and relevant by CHW/Ps, particularly for communicating about research with community members. This course can be a professional development resource for CHW/Ps and could serve as the foundation for a national standardized training on their role related to research best practices.

Psychiatric medications prescribed on-campus and off-campus for university students: Differences in demographics, types of medication, and satisfaction with services

Objective: To describe the use of psychiatric medication and related health service utilization among college students receiving care on- and off-campus. Participants and methods: 3959 students from a large southern university participated in the Healthy Minds Study in May 2018. Results: Of students surveyed, 17.6% took psychiatric medication in the last year. Of these students, 22.0% received prescriptions on-campus, 61.7% received prescriptions off-campus, 6.4% received them both on- and off-campus, and 9.9% took medication without a prescription. Nonwhite, international, and younger students were more likely to utilize on-campus rather than off-campus psychiatric medication services (p < .05). Satisfaction with health services did not differ by location. Conclusions: The majority of students received psychiatric prescriptions off- rather than on-campus. While satisfaction with both on- and off-campus health services is equally high, minority, international, and younger students are more likely to seek care on- rather than off-campus.

Polysubstance use profiles among US adults using Kratom (Mitragyna speciosa): A latent class analysis using The National Survey on Drug Use and Health (NSDUH)

BACKGROUND AND OBJECTIVES

Kratom (Mitragyna speciosa) use is associated with polysubstance use (PSU) and use disorders. However, additional research on PSU heterogeneity in populations using this novel psychoactive substance is necessary. The authors investigated patterns of past 12-month PSU among US adults reporting past 12-month use of kratom and at least one additional substance.

METHODS

Latent class models were fit using 2019 National Survey on Drug Use and Health (NSDUH) data which was collected from 412 US adults reporting past 12-month use of kratom and at least one of 11 additional substances.

RESULTS

Three distinct profiles were identified: "marijuana/alcohol/tobacco" (63.3%), "marijuana/alcohol/tobacco + psychedelics" (19.3%), and "marijuana/alcohol/tobacco + psychedelics/heroin/prescriptions" (17.4%).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

This is the first epidemiological study in which a latent class analysis was used to identify unique PSU profiles among US adults using kratom and other substances. Understanding the profiles of people using kratom in relation to the use of other drugs might help guide screening interventions, treatment needs, and policy.

Current psychiatric treatment for college students with depression only, anxiety only, or comorbid depression & anxiety (2013-2019)

BACKGROUND

This epidemiological study described changes in the estimated prevalence of current pharmacological and/or psychotherapy-based treatment utilization among college students with depression only, anxiety only, or comorbid depression & anxiety.

METHODS

A sample of 190,500 weighted responses was collected through the 2013-2019 Healthy Minds Study questionnaires. Annual prevalence estimates of depression only, anxiety only, or comorbid depression & anxiety were computed. Current use of therapy, pharmacological services, or dual treatment among students with depression and/or anxiety were examined via descriptive statistics.

RESULTS

Estimated prevalence of college students who screened positive for depression only, anxiety only, and comorbid depression & anxiety escalated from 2013 to 2018-2019. When assessed individually, rates of currently using any psychiatric medication, participating in therapy, and engaging in concurrent medication & therapy services significantly rose among students with depression and/or anxiety. However, temporal trends in the current use of specific classes of psychiatric medications among young adults with depression only, anxiety only, or comorbid depression & anxiety differed by medication class.

LIMITATIONS

This study was unable to assess psychiatric prescribing practices, depression or anxiety diagnoses, and prior mental health treatment.

CONCLUSIONS

An increasing proportion of college students are reporting depression and/or anxiety symptoms as well as pharmacological and/or psychotherapy service utilization when comparing rates from 2013 to 2018-19. Although this may indicate increasing acceptability to disclose and seek treatment for problematic symptomology, continued surveillance of college populations is needed to identify students at risk for adverse psychiatric health outcomes, especially during the coronavirus disease 2019 pandemic.

Perceptions of Research Participation among a Sample of Florida Residents Aged 50 and Over Reporting Dementia

As the population ages, the prevalence of dementia will increase. More research is needed; however, low rates of research participation, especially by older adults, hinder progress. Data came from HealthStreet, a University of Florida community engagement program in which community health workers assess community members for their health conditions. Adults 50 and over were included in these analyses; their perceptions of health research studies were assessed. Our sample had an average age of 60.5 years and 4.3% reported dementia (n = 4,881). Overall, older adults reported a high willingness to participate in research. Individuals who reported dementia had 0.64 times the odds of reporting willingness to participate in a research study that required an overnight stay, compared to those who did not report dementia (95% CI: 0.45-0.89). We report on willingness to participate in research in a more granular basis than has been previously done. Community members reporting dementia, compared to those without, were as or more likely to desire future participation in health research. However, barriers to participation remain and must be addressed.

Screening the "Invisible Population" of Older Adult Patients for Prescription Pain Reliever Non-Medical Use and Use Disorders

Background: In the United States, the number of older adults reporting non-medical use of prescription pain relievers (NMUPPR) between 2015 and 2019 has remained constant, while those meeting criteria for opioid use disorders (OUDs) between 2013 and 2018 increased three-fold. These rates are expected to increase due to increased life expectancy among this population coupled with higher rates of substance use. However, they have consistently lower screening rates for problematic prescription pain reliever use, compared to younger cohorts. Objectives: This commentary reviewed trends in older adult NMUPPR and OUDs and reviewed several available screening tools. We then considered reasons why providers may not be screening their patients, with a focus on older adults, for NMUPPR and OUDs. Finally, we provided recommendations to increase screenings in healthcare settings. Results: Low screening rates in older adult patients may be due to several contributing factors, such as providers' implicit biases and lack of training, time constraints, and comorbid conditions that mask NMUPPR and OUD-related symptoms. Recommendations include incorporating more addiction-related curricula in medical schools, encouraging participation in CME training focused on substance use, attending implicit bias training, and breaking down the silos between pharmacy and geriatric, addiction, and family medicine. Conclusions: There is a growing need for older adult drug screenings, and we have provided several recommendations for improvement. By increasing screenings among older populations, providers will assist in the identification and referral of patients to appropriate and timely substance use treatment and resources to ultimately ameliorate the health of older adult patients.

Test-retest reliability of a new assessment to detect detailed temporal patterns of polysubstance use

OBJECTIVE

While polysubstance use is highly prevalent among people who use drugs, the field lacks a reliable assessment that can detect detailed temporal patterns of polysubstance use. This study assessed the test-retest reliability of the newly developed Polysubstance Use-Temporal Patterns Section (PSU-TPS).

METHODS

Participants who used cocaine plus alcohol and/or marijuana at least once in the past 30 days (n = 48) were interviewed at baseline and approximately 7 days later (retest) using the Substance Abuse Module and the PSU-TPS. Reliability of PSU-TPS measures of quantity, frequency, and duration of polysubstance use was examined using intra-class correlation coefficients (ICCs) and kappa tests.

RESULTS

Excellent reliability was observed for frequencies of concurrent polysubstance use patterns in the past 30 days (ICC range: 0.90-0.94) and quantity of alcohol use (ICC = 0.83), and fair to good reliability was observed for duration of substance use (ICC range: 0.52-0.73).

CONCLUSION

Detailed information regarding cocaine, alcohol, and marijuana polysubstance use in the past 30 days can be reliably measured with the PSU-TPS. Data on the order and timing of polysubstance use at the hourly level will improve our understanding of the implications of sequential and simultaneous use patterns, which can help inform treatment and prevention efforts.

Health Effects Associated With Kratom (Mitragyna speciosa) and Polysubstance Use: A Narrative Review

Background

Kratom (Mitragyna speciosa) consumption and associated health effects have raised debates in the United States. Although most people using this herb do not experience adverse health effects associated with kratom use, medical providers should be knowledgeable of emerging substances and concurrent, sequential, or simultaneous use of other drugs which may impact healthcare recommendations and prescribing practices.

Methods

The objective of this narrative review was to elucidate selected health effects associated with using kratom-either alone or with other substances. Since scientifically controlled human subjects research on kratom use is still limited, relevant case reports were also described.

Results

Cardiovascular, gastrointestinal, neurological, and psychiatric effects associated with kratom use were especially notable, and in-utero exposure accompanied concern regarding a neonate's risk for developing neonatal abstinence syndrome. Our ability to identify and understand the role of this herb in kratom-associated fatalities is complicated since kratom is not routinely screened for in standard forensic toxicology. If a screening is performed, it is usually for the major alkaloid, mitragynine, as a surrogate for kratom use. In addition to lacking a standard practice of screening decedents for kratom alkaloids, the association between mortality and kratom use may be confounded by polysubstance use, adulteration of kratom products, and drug-herb interactions.

Conclusions

Increasing medical awareness of this herb is vital to ensuring prompt administration of best-practice medical advice or treatment for people seeking information related to kratom use or for patients experiencing an adverse health effect that may be associated with using or withdrawing from kratom. Knowledge gained from continued surveillance and study of kratom and its associated health effects may assist in guiding clinical decision-making and preventing development of adverse health effects among people using kratom.

Hepatitis D-associated hospitalizations in the United States: 2010-2018

In the United States, hepatitis D is not a reportable condition, leading to gaps in epidemiological and clinical knowledge. We aim to estimate the incidence of hepatitis D-associated hospitalizations in the United States and describe the clinical, demographic and geographic characteristics of those hospitalizations. We utilized hospitalization data from the 2010-2018 National Inpatient Sample from the Healthcare Cost and Utilization Project. Hepatitis D and hepatitis B only (HBV only) hospitalizations were identified by International Classification of Diseases, Ninth Revision (ICD-9) and International Classification of Diseases, Tenth Revision (ICD-10) codes. We identified 3825 hepatitis D-associated hospitalizations. The hospitalization rate of hepatitis D was between 6.9 and 20.7 per 10,000,000 but did not change significantly over time. Compared to HBV only, the hepatitis D cohort had a greater proportion of males, Hispanics, hospitalizations in the Northeast region. The hepatitis D-associated hospitalizations also had significantly greater frequencies of liver failure, non-alcoholic cirrhosis, portal hypertension, ascites and thrombocytopenia. While mortality in hepatitis D was similar to that of HBV only, age >65 years (odds ratio [OR] = 3.79; p = .020) and having a diagnosis of alcoholic cirrhosis (OR = 3.37; p = .044) increased the odds of mortality within the hepatitis D cohort. Although the hepatitis D-associated hospitalizations were relatively uncommon, they were associated with severe complications.

Study Navigation and Enrollment in a Community Sample: Does Generational Cohort Matter?

The socioecological model (SEM) was used as a conceptual framework to examine the effect of generational cohorts on study navigation and enrollment in health research. The study population was 7,370 community-dwelling Gen Xers and Baby Boomers in North Central Florida. Analyses found that Leading-edge Boomers (individuals born between 1946 and 1955) [vs Gen Xers (individuals born between 1965 and 1955)] and individuals with higher trust (vs lower trust) were 41% and 25% respectively more likely to be enrolled in health research compared to their counterparts, controlling for factors at the individual, relationship, and community levels of the SEM. We conclude the study with a summary of the findings and the recruitment implications for study enrollment.

The Marijuana Associated Planning and Long-term Effects (MAPLE) Study: Protocol of a Longitudinal Cohort of Marijuana Use and Health Outcomes in Persons living with HIV (Preprint)

Background

Marijuana use is common in persons with HIV, but there is limited evidence of its relationship with potential health benefits or harms.

Objective

The Marijuana Associated Planning and Long-term Effects (MAPLE) study was designed to evaluate the impact of marijuana use on HIV-related health outcomes, cognitive function, and systemic inflammation.

Methods

The MAPLE study is a longitudinal cohort study of participants living with HIV who were recruited from 3 locations in Florida and were either current marijuana users or never regular marijuana users. At enrollment, participants completed questionnaires that included detailed marijuana use assessments, underwent interviewer-administered neurocognitive assessments, and provided blood and urine samples. Ongoing follow-ups included brief telephone assessments (every 3 months), detailed questionnaires (annually), repeated blood and urine samples (2 years), and linkage to medical records and statewide HIV surveillance data. Supplemental measures related to intracellular RNA, COVID-19, Alzheimer disease, and the gut microbiome were added after study initiation.

Results

The MAPLE study completed enrollment of 333 persons between 2018 and 2021. The majority of participants in the sample were ≥50 years of age (200/333, 60.1%), male (181/333, 54.4%), cisgender men (173/329, 52.6%), non-Hispanic Black (221/333, 66.4%), and self-reported marijuana users (260/333, 78.1%). Participant follow-up was completed in 2022, with annual updates to HIV surveillance data through at least 2027.

Conclusions

The MAPLE study is the largest cohort specifically designed to understand the use of marijuana and its effects on HIV-related outcomes. The study population has significant diversity across age, sex, gender, and race. The data will help clinicians and public health officials to better understand patterns of marijuana use associated with both positive and negative health outcomes, and may inform recommendations for future clinical trials related to medical marijuana and HIV.

Prescription Opioid Use Among a Community Sample of Older and Younger Women

Background: Women bear a heavier burden of the consequences related to prescription opioid use compared to their male counterparts; however, there has been little attention in the literature regarding prescription opioid use among women. We aimed to examine risk factors for prescription opioid use among women. Methods: Demographics, health status, and substance use data, including prescription opioid use, were collected through a community engagement program, HealthStreet, during a health needs assessment. Women older than 18 years were classified by opioid use: past 30-day, lifetime, but not past 30-day, or no lifetime prescription opioid use. Descriptive statistics and chi-square tests were calculated, and multinomial logistic regression was used to calculate adjusted odds ratios (aORs; confidence interval [CI]). Results: Among 5,549 women assessed, 15% reported past 30-day use and 41% reported lifetime use of prescription opioids. While prescription sedative use was the strongest risk factor for past 30-day use among younger women (aOR = 4.84; 95% CI, 3.59-6.51), past 6-month doctor visits was the strongest risk factor for past 30-day use among older women (aOR = 4.15; 95% CI, 2.62-6.60). Conclusions: We found higher rates of prescription opioid use in this community sample of women compared to national rates. Risk factors for recent prescription opioid use (past 30-day use) differed among older and younger women. Clinicians should be more vigilant about prescribing opioids as the medical profile for women may change through age, especially the co-prescribing of opioids and sedatives.

E-cigarettes and non-suicidal self-injury: Prevalence of risk behavior and variation by substance inhaled

BACKGROUND

Nicotine and cannabis inhalation through vaping or electronic delivery systems has surged among young adults in the United States, particularly during the coronavirus disease pandemic. Tobacco and marijuana use are associated with select adverse mental health outcomes, including symptoms of major depressive disorder and suicidal behaviors. Given the need for addiction specialists to treat problematic substance use with an integrated approach, the association between non-suicidal self-injury (NSSI) and use of e-cigarettes, tobacco, marijuana, and alcohol was examined among a diverse sample of college students.

METHODS

Healthy Minds Study data from 47,016 weighted observations, collected from college students in the 2018-2019 academic year, was used to explore associations between NSSI-related behaviors and past 30-day use of a vaping product (nicotine or marijuana). These relationships were assessed among those using vaping products only, and then among individuals using vaping products and alcohol, conventional cigarettes, and/or marijuana. Hierarchical logistic regression models estimating the relationship between vaping and NSSI were computed to adjust for the effects of demographic factors, symptomatology of psychiatric disorders, and concurrent use of other substances.

RESULTS

A fifth (22.9%) of respondents disclosed past 12-month NSSI; they were significantly more likely to screen positive for depression or anxiety compared to young adults without NSSI. Rates of using vaping products, conventional cigarettes, marijuana, or other substances were higher among students with NSSI even after controlling for potential cofounders. Additionally, students who used a THC-based liquid in their e-cigarettes were more likely to endorse NSSI in comparison to those who used "just flavoring." However, young adults who vaped were less likely to disclose frequent NSSI-related behaviors than their peers who did not vape.

CONCLUSIONS

These findings revealed an association between past 12-month NSSI and past 30-day vaping in a sample of young adults. Further surveillance among college populations and examination of potential sociodemographic confounders is necessary to confirm these findings and advance the substance use and addiction field.

Prescription stimulant brand name recognition among a national sample of 10- to 18-year-old youth

OBJECTIVE

The majority of prescription drugs, including prescription stimulants, are marketed using multiple brand names, doses, and formulations. There is limited research on the extent to which individuals correctly identify medication by brand name or packaging, but such identification is important for epidemiological studies especially among youth. Testing the ability of youth to identify medications was one aim of the National Monitoring of Prescription Stimulants Study, which focused on the prevalence of prescription stimulant use among youth.

METHODS

Using the entertainment venue intercept method, youth 10 to 18 years of age (n = 11,048) were recruited across 10 metropolitan areas throughout the United States, shown pictures of eight formulations of prescription stimulants, and asked to identify them by name, dosage, and formulation.

RESULTS

Overall, 27% of youth reported having seen one of the eight stimulant formulations and between 2% and 70% correctly identified name, dose, and formulation. Youths' reports of having seen and correctly identifying medication increased with age except for Daytrana^® . Specifically, while 2.8% of youth reported using Adderall^® in the past 30 days, only 71.4% correctly identified it.

CONCLUSIONS

These results provide strong evidence of the need for more stringent methods for youth to report drug use.

Test-retest reliability and cross-cultural applicability of DSM-5 adopted diagnostic criteria for ketamine use disorders

BACKGROUND

Despite increasing prevalence of nonmedical ketamine use globally, data on ketamine use disorders, which are classified in the DSM-5 under criteria for phencyclidine, are limited. This study assessed the reliability and applicability of DSM-based diagnostic criteria for ketamine use disorder.

METHODS

Participants who used ecstasy were recruited through the Tri-City Study of Club Drug Use, Abuse, and Dependence in St. Louis, Miami, and Sydney. Those who reported using ketamine (lifetime use >5 times) were included in these analyses (n = 205). Participants were interviewed using the computerized Substance Abuse Module for Club Drugs (CD-SAM) at baseline and 7 days later for the reliability of diagnoses and individual diagnostic criteria.

RESULTS

Overall, 29.3% met DSM-5 adopted criteria for ketamine use disorder at Time 1. Moderate to excellent test-retest reliability was observed consistently across study sites for any ketamine use disorder (κ = 0.57, Y = 0.61) and severe ketamine use disorder (κ = 0.62, Y = 0.79). Continued use of ketamine despite knowledge of physical or psychological problems was the most frequently endorsed individual criterion (59.0%), followed by reported withdrawal (30.2%) and physically hazardous use (29.8%). All individual criteria had acceptable reliability estimates (κ ≥ 0.41).

CONCLUSIONS

Diagnoses of ketamine use disorder can be reliably evaluated using this fully structured diagnostic instrument's questions and algorithm. Ketamine-related withdrawal among people who use ketamine should be re-evaluated. Considering that after-effects of this dissociative anesthetic can last for many hours, it is important to explore a different timeframe for possible withdrawal effects.

Converging public health crises: substance use during the coronavirus disease 2019 pandemic

PURPOSE OF REVIEW

The international, public health crisis caused by the rapid spread of SARS-CoV-2 has resulted in unforeseen medical and psychiatric consequences. We reviewed publications from January 2020 to January 2021, given that earlier documents were not relevant, to review findings on changes in substance use and overdoses during the pandemic. Additionally, this review of the literature also documents advocacy efforts, health service modification and challenges, as well as COVID-related health complications associated with substance use.

RECENT FINDINGS

Recent work focused on identifying changes in the distribution and use of substances as well as the unique challenges to promoting the health of persons who use substances in the current pandemic. Although COVID-19 has triggered unprecedented innovations in the organizational and public policy, the use of certain substances (alcohol, cannabis, cigarettes, fentanyl, heroin, and opiates) is increasing internationally. Unique associations between substance use and pandemic-related adverse health outcomes were identified. In addition, the pandemic precipitated significant barriers and disruptions to care.

SUMMARY

Given increased overdose rates and infections among people who use drugs, continued surveillance and vigilance are needed to assess changes and reduce use and adverse consequences during the continuing COVID-19 crisis. Changes are urgently needed to reduce adverse health outcomes because of treatment barriers and lack of adequate treatment options. Additionally, integrative approaches are necessary to promote the public health of persons who use substances.

Willingness to Participate in Health Research Among Community-Dwelling Middle-Aged and Older Adults: Does Race/Ethnicity Matter?

INTRODUCTION

Older adults, including racial and ethnic minorities, are underrepresented in research. As the US population ages, the number of older racial and ethnic minority individuals will increase. Including these individuals in research is an important step towards reducing health disparities.

METHODS

We used data from HealthStreet, a University of Florida community engagement program which uses community health workers to assess the health of the community, to assess willingness to participate in different types of health research by race/ethnicity. Descriptive statistics and logistic regression models were used to assess willingness to participate among adults aged 50 and older, by race/ethnicity (n = 4694).

RESULTS

Our sample was 42.0% non-Hispanic White, 52.8% non-Hispanic Black, and 5.2% Hispanic. Non-Hispanic White participants reported more past research participation than non-Hispanic Black and Hispanic participants (28.7% vs. 19.0% and 19.2%, respectively). Compared with non-Hispanic White participants, non-Hispanic Black participants were less willing to participate in most types of studies, while Hispanic participants were less willing to participate in studies that might be seen as invasive (required blood sample, genetic sample, or participants to take medicine, or use of medical equipment).

CONCLUSIONS

Our study provides investigators with a general profile of research preferences by race/ethnicity; compared with non-Hispanic White individuals, non-Hispanic Black individuals are less willing to participate in most studies, while Hispanic individuals are less willing to participate in studies that may be seen as invasive or demanding. It is imperative to include diverse older adults in health research. By tailoring research based on preferences we can improve recruitment in underrepresented populations.

Use of psychiatric medication by college students: A decade of data

OBJECTIVES

Given the rising prevalence of psychiatric symptomatology among college students, this analysis aims to identify temporal trends in psychiatric medication usage.

METHODS

This analysis used data from the Healthy Minds Study Survey administered between 2007 and 2019, yielding a sample of 320,817 university students. Survey data were examined via descriptive analyses.

RESULTS

Over the last decade from 2007 to 2018-2019, there was an increase in use of nearly all classes of psychiatric medications, with reported antidepressant medication (selective serotonin reuptake inhibitors [SSRIs], serotonin-norepinephrine reuptake inhibitors [SNRIs], etc.) use increasing from 8.0% to 15.3%, anti-anxiety medication (benzodiazepines, buspirone, etc.) from 3.0% to 7.6%, psychostimulants from 2.1% to 6.3%, antipsychotics from 0.38% to 0.92%, and mood stabilizers from 0.8% to 2.0% (all p < 0.0001), respectively. In addition, the use of more than one category of medication at a time has increased, from 28.2% in 2007 to 40.8% in 2018-2019 (p < 0.0001). The proportion of students who received their most recent prescription for psychiatric medication from primary care providers has risen from 49.1% in 2007 to 58.8% in 2018-2019 (p < 0.0001), while the proportion receiving these prescriptions from psychiatric providers did not increase significantly and stands at 36.1% in 2018-2019. The percentage of students taking psychiatric medication without a prescription varied from year to year, starting at 11.9% in 2007 and ending at 7.7% in 2018-2019 (p < 0.0001). The proportion of students who discussed their use of psychiatric medication with their doctor or other health professional three or more times in the previous year has increased from 39.2% in 2007 to 49.5% in 2018-2019 (p < 0.0001).

CONCLUSIONS

The proportion of college students who have taken psychiatric medications of all categories has risen in the last decade; these students are increasingly likely to be on more than one kind of psychiatric medication and be treated by healthcare providers at a greater frequency. Despite the growing complexity of student treatment, the proportion of students receiving psychiatric medication management by psychiatric providers has not changed, while the proportion receiving services in primary care settings has increased.

Impact of the COVID-19 Pandemic on Disordered Eating Behavior: Qualitative Analysis of Social Media Posts

BACKGROUND

A growing body of evidence is suggesting a significant association between the COVID-19 pandemic and population-level mental health. Study findings suggest that individuals with a lifetime history of disordered eating behavior may be negatively affected by COVID-19-related anxiety, and prevention measures may disrupt daily functioning and limit access to treatment. However, data describing the influence of the COVID-19 pandemic on disordered eating behaviors are limited, and most findings focus on individuals in treatment settings.

OBJECTIVE

The aim of this study is to characterize the experiences of Reddit users worldwide who post in eating disorder (ED)-related discussion forums describing the influence of the COVID-19 pandemic on their overall mental health and disordered eating behavior.

METHODS

Data were collected from popular subreddits acknowledging EDs as their primary discussion topic. Unique discussion posts dated from January 1 to May 31, 2020 that referenced the COVID-19 pandemic were extracted and evaluated using inductive, thematic data analysis.

RESULTS

Six primary themes were identified: change in ED symptoms, change in exercise routine, impact of quarantine on daily life, emotional well-being, help-seeking behavior, and associated risks and health outcomes. The majority of users reported that the COVID-19 pandemic and associated public health prevention measures negatively impacted their psychiatric health and contributed to increased disordered eating behaviors. Feelings of isolation, frustration, and anxiety were common. Many individuals used Reddit forums to share personal experiences, seek advice, and offer shared accountability.

CONCLUSIONS

Reddit discussion forums have provided a therapeutic community for individuals to share experiences and provide support for peers with ED during a period of increased psychiatric distress. Future research is needed to assess the impact of the COVID-19 pandemic on disordered eating behavior and to evaluate the role of social media discussion forums in mental health treatment, especially during periods of limited treatment access.

Perceived Risk of Weekly Cannabis Use, Past 30-Day Cannabis Use, and Frequency of Cannabis Use Among Pregnant Women in the United States

BACKGROUND

While accumulated evidence has shown that the prevalence of cannabis use among pregnant women in the US has increased in recent years, little is known about the specific subpopulations affected. The aim of this study was to estimate the prevalence and correlates of the perceived risk of weekly cannabis use, past 30-day cannabis use, and frequency of past 30-day cannabis use among US pregnant women.

METHODS

We analyzed data from 2,247 pregnant women 14 to 44 years of age surveyed in the 2015 to 2017 cross-sectional National Survey on Drug Use and Health. Analyses account for the sampling design. Primary outcomes included perceived risk of weekly cannabis use, past 30-day cannabis use, and frequency of cannabis use. We conducted multivariable logistic and negative binomial regression models to assess the associations between the primary outcomes and multiple correlates.

RESULTS

Among US pregnant women, 21.6% (95% CI=19.4, 23.8) did not perceive any risk associated with weekly cannabis use, 5.3% (95% CI=4.2, 6.5) used cannabis in the past 30 days, and among past-month users, the average number of days of use was 15.6 (95% CI=13.5, 17.7). Pregnant women living below the poverty line were both more likely to perceive no risk of weekly cannabis use (aOR=1.8; 95% CI=1.3, 2.5) and use cannabis more often in the past 30 days (aOR=2.9; 95% CI=1.5, 5.7) than pregnant women within an income bracket of more than two times the federal poverty threshold. Age, race, trimester of pregnancy, co-use of tobacco and/or alcohol were also associated with these outcomes.

CONCLUSION

Younger age, living in poverty, early trimester of pregnancy, and co-use of tobacco and/or alcohol increased the odds of cannabis use among pregnant women. As cannabis legalization spreads and cannabis use is increasingly perceived as safe, there is a growing need for research to determine the reasons why women in the identified at-risk subgroups are using cannabis during pregnancy.

Reasons for Prescription Opioid Use While Playing in the National Football League as Risk Factors for Current Use and Misuse Among Former Players

OBJECTIVE

Prescription opioid misuse has become a significant public health issue. Previous research has examined predictors of prescription opioid use and misuse among former National Football League (NFL) players. The present study aimed to describe how reasons for prescription opioid use while in the NFL corresponds to use and misuse in retirement.

DESIGN

Former NFL players reporting prescription opioid use during their playing careers (N = 336) were included in this secondary data analysis. Participants reported reasons for prescription opioid use, including pain management, use "to function," to improve mood, to reduce stress, and to aid sleep.

RESULTS

Among retired NFL players with exposure to prescribed pain medication during their playing career, 26.2% reported recent use of prescription opioids (past 30 days) and 73.8% reported no use. Specifically, 14.3% of retired players reported opioid use only as prescribed, whereas 11.9% reported misuse (not prescribed or use other than as prescribed). Using prescription opioids to function while in the NFL was associated with any opioid use in the past 30 days [odds ratios (OR) = 1.30, 95% CI: 1.12-1.50, P < 0.001]. Further, opioid use in the NFL to reduce stress and anxiety was associated with increased odds of past 30-day misuse of prescription opioids (OR = 1.45, 95% CI: 1.01-2.11; P = 0.048).

CONCLUSIONS

The present study adds to the literature on elite athletes at high risk for pain and prescription opioid use and misuse. The findings may help to identify and provide early intervention for professional athletes most at risk for misuse of prescription opioids.

Correlates related to follow-up in a community engagement program in North Central Florida

AIMS

This analysis identifies the correlates of 60- and 120-day telephone-based study follow-ups among community-dwelling adults in North Central Florida.

METHODS

Six thousand three hundred and forty participants were recruited by Community Health Workers from the University of Florida's community engagement program with a face-to-face baseline and two phone follow-ups assessing indicators of health.

RESULTS

Physical disability versus none (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.2─1.9), high trust in research versus none (aOR, 1.5; 95% CI, 1.1─2.1), history of research participation versus none (aOR, 1.6; 95% CI, 1.3─2.0), having health insurance versus none (aOR, 1.4; 95% CI, 1.1─1.7), interest in research participation versus none (aOR, 1.8; 95% CI, 1.3─2.7), and no drug use versus drug use (aOR, 0.5; 95% CI, 0.3─0.9) significantly predicted completion of follow-up.

CONCLUSIONS

Health and social factors such as disability, insurance, history of and interest in research, trust and no drug use significantly predicted completing two follow-ups. These findings can facilitate efforts to minimize attrition in the research enterprise.

Sex differences in driving under the influence of cannabis: The role of medical and recreational cannabis use

BACKGROUND

Existing evidence suggest that cannabis may impair driving and is the most prevalent drug identified in drivers. Males exhibit an excess risk for driving under the influence of drugs or alcohol compared to females. We assessed sex differences in the association between the reason for cannabis use (medical, recreational, or both) and driving under the influence of cannabis (DUIC).

METHODS

A sample of 17,405 past 12-month cannabis users (18 + years old) were analyzed from the 2016-17 National Survey on Drug Use and Health. Multivariable logistic regression was used to assess the interaction of sex and reason for cannabis use on DUIC using predicted probabilities.

RESULTS

Among cannabis users in the sample, 88.1% used for recreational reasons, 7.8% used for medical reasons, and 4.1% used for medical and recreational reasons. The probability of DUIC was as low as 20% among female medical only users, and as high as 40% among male combined medical and recreational users. Females showed more similar probabilities of DUIC across reasons of use (range 20% to 25%s) than males (range 28% to 40%). The difference in the probability of DUIC between combined medical and recreational users and recreational only users was significantly greater among males than among females (Δ 0.1, p < 0.05).

CONCLUSIONS

The observed effects of sex and reasons for cannabis use on DUIC suggests a need for targeted educational interventions, particularly among males reporting combined medical and recreational marijuana use.

If kids ruled the world, how would they stop non-medical use of prescription drugs?

PURPOSE

We examined ideas about how youth would mitigate non-medical use of prescription medications among their peers.

DESIGN/METHODOLOGY/APPROACH

The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) interviewed 11,048 youth10-18 years of age between 2008 and 2011 from entertainment venues of 10 US urban, suburban, and rural areas. Using a mixed-methods approach, participants completed a survey culminating in open ended questions asking: 1) How should kids your age be told about prescription drugs and their effects?; 2) If you ran the world, how would you stop kids from taking other people's prescription medicines?; 3)Why do people use prescription stimulants without a prescription? Responses from a random sample of 900 children were analyzed using qualitative thematic analyses.

FINDINGS

The random sample of 900 youth (52% female, 40% white, with a mean age was 15.1 years) believed they should be educated about prescription drugs and their negative effects at schools, at home by parents, through the media, and health professionals. Youth would stop kids from using other people's prescription drugs through more stringent laws that restricted use, and education about negative consequences of use. Peer pressure was the most common reason youth gave for using other's pills, though some reported using for curiosity.

ORIGINALITY/VALUE

This analysis shows the importance of considering youth's opinions on non-medical use of prescription medications, which are often overlooked. Studies should disseminate this data from youth to stop the illicit use of prescription drugs among teens and youth.

Racial and Ethnic Differences in Alzheimer's Disease Knowledge Among Community-Dwelling Middle-Aged and Older Adults in Florida

Objective: To compare Alzheimer's disease (AD) knowledge by race and ethnicity in a community sample of middle-aged and older adults aged 50 and over in Florida. Method: Data from HealthStreet, a University of Florida community engagement program, which uses community health workers to assess the health conditions, concerns, and knowledge of community members, was used (n = 842). A multivariate regression model was used to quantify differences in AD knowledge by race and ethnicity. Results: Older age and recruitment from Miami were associated with higher AD knowledge while being non-Hispanic Black, reporting male sex, having less than high school diploma, and reporting food insecurity were associated with lower AD knowledge. Discussion: Hispanics had comparable AD knowledge to non-Hispanic Whites and more knowledge than non-Hispanic Blacks after adjusting for other factors that could differentiate these groups. Almost half of the participants did not know hypertension is a risk factor for AD, highlighting a point of intervention.

Prescription Stimulant Use and Associated Risk Factors for Non-oral Use among 10 to 18 Year Olds

Non-medical use, especially non-oral use, of prescription stimulants is a public health concern. This study analyzed data from the National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS). Users (n = 723) were categorized as oral medical only users (n = 330, 45.6%), any oral non-medical users (n = 270, 37.3%), and any non-oral users (n = 123, 17.0%). The associations between patterns of stimulant use and risk factors were examined using logistic regression. Of the 123 any non-oral users, 79 reported using stimulants intranasally and orally, which was the most prevalent pattern of non-oral use. Among any non-oral users, the most common source of stimulants was from school (63.4%). Non-oral users primarily used stimulants to get high (74.4%) compared to 27.1% among other users. Negative consequences significantly associated with any non-oral use but not with oral non-medical use included needing stimulants to "feel ok," having trouble with teachers, bosses or friends due to stimulant use, and having anxiety and depression symptoms. In this study, non-oral use of prescription stimulants was associated with additional risks of adverse mental health outcomes compared to medical only use and other forms of non-medical use. Stimulant non-oral use interventions should emphasize the risks of intranasal use of stimulants.

Exposure to Medicines in the Family Medicine Cabinet: Is It a Harbinger of Later Opioid Dependence?

Background: Despite research on prescription opioids and dependence being a national priority, little is known about the association between several potential adolescent risk factors and later opioid dependence among those who use opioids non-medically. Objectives: To investigate the association between lifetime opioid dependence and adolescent self-perceived health, health beliefs (thinking there was a pill for everything), health behaviors (onset of alcohol use before 15, onset of prescription opioid use before 15) and parental health practices (having opioids in the family medicine cabinet at age 14, parental suggestions to take pills when sick). Methods: A sample of 343 community members who non-medically used prescription opioids in the past 12 months were recruited for the Prescription Drug Misuse, Abuse, and Dependence Study and retrospectively assessed for adolescent risk factors of lifetime opioid dependence (DSM-IV). Results: Logistic regression revealed the strongest predictor of lifetime opioid dependence was having a prescription opioid in the family medicine cabinet at age 14. Those who grew up believing there was a pill for everything and those who initiated alcohol use before 15 were 1.83 and 1.78 times as likely, respectively, to meet dependence criteria than their counterparts. Demographics and other adolescent predictors were not associated with opioid dependence. Conclusions: Findings suggest several adolescent exposures can be targeted to reduce opioid dependence. Through their behavior, parents can reduce their teens' risk for opioid dependence.

Sex Differences in Willingness to Participate in Research Based on Study Risk Level Among a Community Sample of African Americans in North Central Florida

This study examined the association between sex, study risks and willingness to participate in research among a community sample of African Americans. We hypothesized that African American males would be more willing to participate in studies involving both minimal and greater-than-minimal risk. The study sample was recruited through a community engagement program (HealthStreet). Interviewers obtained information on socio-demographic variables and willingness to participate in various research types. We categorized research types into minimal risk and greater- than- minimal risk based on the IRB classification. The study sample comprised 6544 African-Americans; 58.4% were females. About 92.6% of the participants were willing to participate in surveys and 58.1% in research requiring medication use. More males would participate in minimal risk studies requiring review of medical records (males 87.0% vs. females 84.2%, p = 0.0021) and studies involving giving a blood sample (males 84.2% vs. females 81.7%, p = 0.0083). Also, more males would participate in greater than minimal risk studies involving the use of medication (60.5% v. 56.3% p = 0.0007). More males were willing to participate in minimal risk studies (studies involving the review of medical records and giving blood samples) and greater-than-minimal risk study involving the use of medication.

Disordered eating is associated with non-medical use of prescription stimulants among college students

BACKGROUND

Disordered eating behaviors are associated with non-medical use of prescription stimulants for weight and appetite-related purposes. Yet, estimates of the prevalence and types of disordered eating associated with non-medical use vary. Additionally, little is known about the association between medical use of prescription stimulants and disordered eating.

METHOD

Data were collected from 87,296 college students at 127 institutions that participated in the Healthy Minds Study. We assessed the relationship between disordered eating, medical and nonmedical prescription stimulant use using multivariable logistic regression models adjusted for demographic characteristics, lifestyle and behavioral factors, and psychiatric comorbidity.

RESULTS

Non-medical use of prescription stimulants (NMUPS) was reported by 2.8 % n = 2435 of the sample. One-third of students using prescription stimulants non-medically reported two or more disordered eating attitudes and behaviors. Disordered eating was a significant predictor of non-medical, but not medical use of prescription stimulants. A dose-response relationship was identified between disordered eating and non-medical use, where risk for non-medical use increased with the number of disordered eating attitudes and behaviors reported.

CONCLUSIONS

The risk for NMUPS increases with disordered eating symptomatology. There is a need to assess for NMUPS among college students presenting with disordered eating.

Age of First Use of Prescription Opioids and Prescription Opioid Non-Medical Use among Older Adolescents

Non-medical use (NMU) of prescription opioids is of concern due to the opioid epidemic in the United States. Objective: We examined sex differences in the effect of age of first use of prescription opioids on prescription opioid NMU among 17- and 18-year olds. Methods: The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) recruited youth 10-18 years from 10 United States cities between 2008 and 2011 (n = 11,048). The cross-sectional survey included questions on past 30 day prescription opioid use (10,965 provided responses; 278 age 17 to 18 years who used opioids in past 30 days), with NMU defined as non-oral use and/or use of someone else's opioids. Nonparametric survival analysis with lifetable estimates was used to examine age at first use. Binomial logistic regression was conducted predicting any NMU, adjusted for covariates. Results: Among 278 youth 17 to 18 years, a significant difference in age of first use between those with MU only and any NMU (p < .0001) was observed. Each one year increase in age resulted in a 33% decrease in the odds of any prescription opioid NMU compared to MU only, after controlling for covariates (Odds Ratio = 0.67, 95% Confidence Interval: 0.47,0.96). Sex differences in age at first use were not observed. Conclusions: Risk of past 30 day prescription opioid NMU decreased by a third for each one year increase in age of first use, after adjustment for other covariates. Use of prescription opioids in young adolescents may need to be limited where possible and researched further.

Sex differences in prescription opioid use patterns assessed through a community engagement program in Florida

BACKGROUND

Morbidity and mortality attributed to prescription opioids are a crisis in the US and spreading globally. Sex differences related to these conditions have not been adequately assessed.

METHODS

Through our community engagement program, data on demographics, health status, and substance use, including prescription opioids (e.g., Vicodin®, Oxycodone), were collected from community members in Florida (primarily North Central Florida) during a health needs assessment. Participants over 18 years of age were classified by opioid use: past 30-day, lifetime but not past 30-day, or no lifetime prescription opioid use. Descriptive statistics and chi-square tests were calculated, and multinomial logistic regression was used to calculate adjusted odds ratios (aOR; CI). Analyses were conducted for men and women separately to examine sex specific effects.

RESULTS

Among 9221 community members assessed, the mean age was 45 years, 60% were female, and 58% were black. Respondents who endorsed past 30-day use and lifetime use were more likely to be female. Prescription sedative use was the strongest risk factor for past 30-day (aOR = 3.96; 95% CI, 3.35-4.68) and lifetime (aOR = 2.67; 95% CI, 2.34-3.04) prescription opioid use, regardless of sex. Other factors including marijuana use and history of cancer were significantly associated with prescription opioid use; they varied by sex.

CONCLUSIONS

The risk factors identified in this community sample provide additional information not accounted for by national studies. Future examinations of the consequences of concomitant opioid and sedative use, especially among women, are needed.

Sex differences in peer and parental risk factors for non-medical use of prescription opioids in youth

Background: Prescription opioid non-medical use (NMU) and its associated consequences have been of concern in the US in recent years.Objective: We examined peer influence and parental guidance, in addition to peer and parental sources of alcohol, on patterns of prescription opioid use, including NMU, among males and females separately. We hypothesized that peer influence and parental guidance would have a differential influence for males and females.Methods: The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) recruited youth 10-18 years from 10 US cities between 2008 and 2011 (n = 11,048). The cross-sectional survey included questions on past 30-day prescription opioid use (10,965 provided responses), with NMU defined as non-oral use and/or use of someone else's opioids. Multinomial logistic regression was conducted, examining medical use only and NMU in the past 30 days.Results: Among the 10,965 youth, 3.1% (n = 345) reported past 30-day NMU. Obtaining alcohol from parents was associated with increased odds of past 30-day NMU among males (OR = 2.49, 95%CI: 1.54,4.03) only. For each additional close friend who used other substances, odds of past 30-day NMU increased among males (OR = 1.23, 95%CI: 1.11,1.37) and females (OR = 1.15, 95%CI: 1.04,1.27). Increased number of close friends was associated with decreased odds of past 30-day NMU among males (OR = 0.87, 95%CI: 0.78,0.97) and females (OR = 0.86, 95%CI: 0.77,0.96).Conclusions: Peer and parental risk factors for prescription opioid NMU were identified among youth, although not all differed by sex. An increased number of close friends was a protective factor against prescription opioid NMU for both males and females.

Willingness of individuals with eating disorders to participate in health research

BACKGROUND/AIMS

This study examines the association between eating disorders (EDs) and willingness to participate in health research studies among community members.

MATERIALS & METHOD

Data were collected from Health Street, a University of Florida community engagement initiative which aims to reduce disparities in healthcare and health research by direct engagement of community members.

RESULTS

Among 8,226 community members, 3.9% (n = 324) reported a lifetime ED. For all six types of health research studies queried, individuals with a lifetime ED reported a higher willingness to participate in health research compared to individuals without a history. After adjusting for selected covariates, individuals with ED were significantly more likely than individuals without ED to say they would be willing to volunteer for research studies that: ask questions about health (OR: 7.601, 95% CI: [1.874, 30.839]); require an overnight stay in a hospital (OR: 2.041, 95% CI: [1.442, 2.889]); and provide no remuneration (OR: 1.415, 95% CI: [1.022, 1.958]). Furthermore, when compared to individuals with anxiety or depression, individuals with ED reported increased interest in research participation and increased willingness to participate in most types of research studies assessed. After stratifying by gender and race, we observed few differences in willingness to participate in research among individuals with ED.

DISCUSSION

These findings contribute to our current understanding of participant recruitment and enrollment in ED health research. Underrepresented populations who often do not seek treatment for EDs endorsed a high willingness to participate.

CONCLUSION

Future studies will likely benefit from including community members in ED research.

Discriminative Ability of Montreal Cognitive Assessment Subtests and Items in Racial and Ethnic Minority Groups

INTRODUCTION

The Montreal Cognitive Assessment (MoCA) is a popular screening tool for Mild Cognitive Impairment (MCI). The psychometric properties of the MoCA have not been widely examined in minority groups. We aimed to analyze the discriminate ability of subtests and items by race and ethnicity given gold-standard clinical diagnosis of cognitive status.

METHODS

We analyzed data from the National Alzheimer Coordinating Center Uniform Data Set March 2018 data freeze. Stepwise regression was used to determine which subtests predicted cognitive status (normal cognition, MCI, or dementia), by race/ethnicity. Item discrimination and difficulty was calculated by race/ethnicity and cognitive status.

RESULTS

In our sample (n=3895), with an average age of 69.7, 80.7% were non-Hispanic white, 15.0% were non-Hispanic black, and 4.2% were Hispanic. Among non-Hispanic whites all subtests, education, and age predicted clinician diagnosis, while visuospatial/executive, attention, language, delayed recall, and orientation subtests were predictive among non-Hispanic blacks and visuospatial/executive, delayed recall, and orientation subtests and education were predictive among Hispanics. Item discrimination and difficulty varied by race/ethnicity and cognitive status.

CONCLUSIONS

By understanding the psychometric properties of MoCA subtests, we can focus on subtests that have higher discrimination and more diagnostic utility. Subtests should be further evaluated for use in screening of minority individuals.

Motives for prescription stimulant use by patterns of non-medical use

Background

Understanding motivations behind non-medical use of prescription stimulants (NMUPS) is important to prevent such use.

Methods

Adult participants from St. Louis, MO, who endorsed NMUPS on 5 or more days in the past 12 months (n=60) were asked about their motivations for use. Associations between motives for use and patterns of non-medical use in the past 12 months were assessed using multivariable logistic regression, controlling for demographic factors and non-medical use of other prescription drugs.

Results

On average, 5.5 different motives for stimulant use were endorsed. Compared to those who only used someone else's stimulants, adults who only used stimulants other than prescribed were less likely to endorse use "to get high" (aOR=0.48, 95%CI 0.26-0.90) and more likely to endorse use "to function" (aOR=1.97, 95%CI 1.04-3.75); adults who were engaged in both patterns of NMUPS were more likely to endorse use "to function" (aOR=4.12, 95%CI 1.56-10.88) and "to modify the effects of other drugs" (aOR=2.29, 95%CI 1.13-4.61).

Conclusion

Although using stimulants for performance enhancement is common, most people who used diverted stimulants reported using stimulants to get high. Prevention and harm reduction strategies should consider these differences.

Order in The Court? The Association Between Substance Use, Exposure to Violence, Risky Sexual Behaviors & Observed Court Behaviors Among Women Involved in the Criminal Justice System

Drug courts, therapeutic justice programs for individuals charged with drug offenses, have sub-optimal completion rates. The Courtroom Behavior Checklist (CRBCL), an assessment that quantifies readiness for drug court and drug court behaviors, was developed to predict female offenders who may be at-risk for non-compliance and termination. Data derived from 264 mainly urban women recruited from a Municipal Drug Court System in St. Louis, MO, were used to evaluate the association between substance use, victimization, HIV/AIDS risk behaviors, and observed drug court behaviors. Results showed that women who reported recent substance use or were categorized as at risk for HIV/AIDS were significantly more likely to have scores indicative of unfavorable drug court behaviors, while women who experienced victimization had scores indicative of favorable drug court behaviors. Other factors significantly associated with unfavorable drug court behaviors included greater lifetime arrests, lower education, and being less religious or spiritual. Our findings suggest that the CRBCL may have added utility in identifying women in drug court with recent substance use and risky sexual behaviors. However, further studies on other samples of offenders are needed to support these findings.

From primary care to the revolving door of hospital readmission: Relevance of Geoffrey Rose's call for a population strategy

The high-risk strategy in prevention has remained the preferred approach in health care. High-profile research predominantly emphasizes specific high-risk subgroups such as those who have extremely high cholesterol and super-utilizers of emergency departments. Dr. Geoffrey Rose's alternative population approach, though well established in principle, has failed to come to fruition in primary care research, aside from a few exceptions. The population approach extends intervention efforts to more moderate-risk people, attempting to shift the overall distribution in a positive direction, effecting change in more of the population. Despite requiring more initial investment due to the larger target group, the health-related gains and downstream cost savings through a population strategy may yield greater long-term cost-effectiveness than the high-risk strategy. We describe the example of extending prevention efforts from super-utilizers (e.g. those with ≥3 readmissions per year) to include those who readmit in moderate frequency (1–2 per year) in terms of potential hospital days and associated medical costs averted.

Association of pleasant sensations at cigarette smoking initiation with subsequent tobacco product use among U.S. adolescents

Approximately 20% of high school students and 7% of middle school students in the United States used tobacco products in 2016. One factor that may contribute to tobacco use is pleasant sensations - typically characterized as physiological reinforcement such as a dopamine response, or as social reinforcement such as social acceptance. In the present study, the Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health (PATH) Study was analyzed to examine the influence of pleasant sensations at cigarette smoking initiation on current use of other tobacco products among adolescents. While those who reported higher unpleasant sensations at cigarette smoking initiation were less likely to report current use of any tobacco product(s) (Odds Ratio [OR] = 0.70), those who reported higher pleasant sensations at cigarette initiation were more likely to report current use of any tobacco product(s) (OR = 2.12) - including: cigarettes (OR = 2.09), cigars (OR = 1.58), hookah (OR = 1.37), and e-cigarettes (OR = 1.37). Based on these findings, interventions for smoking education and further surveillance may benefit adolescents who report higher pleasant sensations at cigarette smoking initiation.

Sex differences in patterns of prescription opioid non-medical use among 10-18 year olds in the US

BACKGROUND

Non-medical use (NMU) of prescription opioids is a public health concern and sex differences in prevalence of NMU have been observed previously. Little is known about how youth are obtaining and using these drugs. While any regular use could be problematic, NMU is particularly concerning. More information is needed on NMU patterns among youth and how these patterns might differ by sex.

METHODS

The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) recruited youth 10-18 years of age from 10 US metropolitan areas from 2008 to 2011 with a final sample of 11,048 youth. The cross-sectional survey included questions on past 30 day use of prescription opioids (10,965 provided responses), with NMU defined as non-oral use and/or use of someone else's opioids. NMU through use of a patient's own prescription orally for a reason other than prescribed could not be identified, though this is usually contained within the standard definition of NMU.

RESULTS

Among the 10,965 youth, past 30 day prevalence of NMU of prescription opioids was 3.1% (n = 345) with 59.7% (n = 206) using someone else's opioids only, 5.2% (n = 18) having non-oral use only and 35.1% (n = 121) having both. In total, seven sources and three routes of administration were assessed. The most common source among males was someone from school (n = 111, 60.0%), with no highly prevalent second source. Among females, there were two prevalent sources of prescription opioids; a parent (n = 59,41.6%) and someone from school (n = 53,37.3%). For non-oral use, snorting prescription opioids was more frequent among males compared to females (n = 85, 31.8% and n = 44, 17.1%; p < .01).

CONCLUSIONS

Based on these findings, to combat the current opioid crisis, implementation of strategies to prevent youth from sharing opioids, especially with friends from school, should be considered and tested.

Prevalence of Concurrent Prescription Opioid and Hazardous Alcohol Use Among Older Women: Results from a Cross-Sectional Study of Community Members

Concurrent use of prescription medications and alcohol is prevalent among older adults and impacts women more than men, however little is known about characteristics of older women who use both. The current analysis aims to evaluate those characteristics. Participants were recruited through HealthStreet, an outreach program. Community health workers (CHWs) assess health needs and concerns among community members. CHWs collect demographic, substance use, and other health data from participants. Female participants (≥ 50 years) interviewed November 2011-November 2017 were included and stratified into four groups: neither prescription opioid nor hazardous alcohol use (three or more drinks in a single day), hazardous alcohol use only, prescription opioid use only, and both prescription opioid and hazardous alcohol use. Chi square and ANOVA tests were used to compare these groups. Among the 2370 women (53% black; mean age 61 years), 70% reported neither prescription opioid nor hazardous alcohol use, 12% reported hazardous alcohol use only, 15% reported prescription opioid use only, and 3% reported use of both in the past 30 days. Concurrent prescription opioid and hazardous alcohol use were significantly associated with comorbid depression and anxiety (p < 0.0001); women who endorsed prescription opioid use only were significantly more likely to report a history of back pain, cancer, or diabetes compared to their counterparts (p < 0.0001). Nearly a third of women reported prescription opioid and/or hazardous alcohol use in the past 30 days. Because the risk and consequences of concomitant alcohol and opioid use increase with age, interventions tailored to women are needed.

Community perceptions related to brain donation: Evidence for intervention

INTRODUCTION

Research progress on neurocognitive disorders requires donation of both healthy and diseased brains. Here, we describe attitudes toward brain donation among a large community sample in Florida.

METHODS

HealthStreet, a community engagement program at the University of Florida, used community health workers to assess community attitudes toward research participation, including brain donation.

RESULTS

Over 60% of people, primarily Caucasian and employed, indicated that they would be likely or somewhat likely to donate their brain for research. Those who would be willing to donate were also more likely to be willing to participate in other research studies and to have participated in research.

DISCUSSION

Brain donation will add to the science of disorders of aging, including accurate diagnoses and validation of in vivo biomarkers. Increasing willingness to donate is a first step toward donation. Community populations are willing; community health workers can educate others about the need for this initiative in communities.

A Longitudinal Analysis of the Substance Abuse, Violence, and HIV/AIDS (SAVA) Syndemic among Women in the Criminal Justice System

Using data from a randomized controlled trial of 319 women mainly recruited from a Municipal Drug Court System in St. Louis, MO, this study evaluates substance use, victimization, and HIV/AIDS risk behaviors over time. The results indicated that, for all participants, the likelihood of victimization, using drugs, and meeting the criteria for HIV/AIDS risk decreased by 46% by the eight-month follow-up; however, results did not differ significantly by intervention group. Women who were sexually abused as a child, had 4+ arrests, or believed they had sexual and drug-using behaviors that need changing at baseline were more likely to experience these issues over time.

Optimal cutoffs for the Montreal Cognitive Assessment vary by race and ethnicity

Introduction

The Montreal Cognitive Assessment (MoCA), scored from 0 to 30, is used as a screening tool for mild cognitive impairment (MCI). The current cutoff (26) may not be optimal among minorities.

Methods

Data from the National Alzheimer's Coordinating Center Uniform Data Set March 2018 data freeze was used to calculate optimal cutoffs for detection of MCI and dementia by race/ethnic group and education.

Results

Of the 3895 individuals included, 80.7% were non-Hispanic White, 15.0% were non-Hispanic Black, and 4.2% were Hispanic. Optimal cutoffs for detection of MCI were 25 among non-Hispanic Whites, 24 among Hispanics, and 23 among non-Hispanic Blacks. Optimal cutoffs for detection of dementia were 19 among non-Hispanic Whites and 16 for both non-Hispanic Blacks and Hispanics. Lower educational attainment produced lower optimal cutoffs.

Discussion

Our findings suggest cutoffs may need to be stratified by race/ethnicity and education to ensure detecting MCI from normal and MCI from dementia.

•

The current MoCA cutoff of 26 is too global and too high for detection of MCI.

•

Optimal MoCA cutoffs vary by race/ethnicity.

•

Cutoffs also vary by educational attainment.

•

Cutoffs should be stratified by race/ethnicity and education before they are applied.

One Step at a Time: A Latent Transitional Analysis on Changes in Substance Use, Exposure to Violence, and HIV/AIDS Risk Behaviors among Female Offenders

The aim of this analysis is to identify latent subgroups of women based on substance use, exposure to violence, and risky sexual behaviors and quantify discrete stages of behavior change over time. Data comes from 317 women recruited from a Municipal Drug Court System in the Midwest. All participants were interviewed regarding their substance use and sexual behaviors, as well as their exposure to violence at baseline, a 4th-month follow-up, and an 8th-month follow-up. A latent transitional analysis (LTA), a longitudinal extension of a latent class analysis (LCA), was used to quantify discrete stages of behavior change. The results of our analyses revealed 4 distinct behavioral profiles in our sample: 1) women with high probabilities of risky sexual behaviors, exposure to violence, and crack/cocaine use, 2) women with a high probability of exposure to violence, and moderate sexual risk taking, 3) women characterized solely by a high probability of crack/cocaine use, 4) women with low probabilities of all factors. The proportion of women in latent statuses characterized by a high probability of crack/cocaine use did not substantially decrease over time. Women who experienced child sexual abuse, had a greater number of lifetime arrests, were older, and believed they had risky drug using behavior that needed changing at baseline were significantly more likely to be in higher-risk latent statuses. Targeted interventions tailored to crack/cocaine users, as well as a wide-spread need for trauma-informed interventions among females involved in the criminal justice system, are needed.

Exposure therapy for youth with anxiety: Utilization rates and predictors of implementation in a sample of practicing clinicians from across the United States

Exposure therapy is a highly effective, evidence-based treatment technique for children and adolescents with anxiety disorders. Regardless, therapists in the community are reported to use exposure relatively rarely compared with other approaches. The goal of the present study was to identify how practicing clinicians treat youth with anxiety disorders across the United States and what factors contribute to their use of exposure therapy. Recruited from public directories, 257 private practice therapists who treat anxious youth were surveyed. Non-exposure cognitive-behavioral techniques like cognitive restructuring and relaxation techniques were used significantly more frequently than exposure. Providers with more training in exposure therapy and fewer negative beliefs about this approach reported using exposure significantly more in the treatment of youth with social anxiety, obsessive-compulsive, and panic disorders. Self-identification as an anxiety disorder specialist significantly predicted exposure use for youth with posttraumatic stress disorder. Most therapists in private practice have minimal training in exposure therapy, perceive a lack of training options, and believe there would be a benefit to acquiring more training. The implications of these findings are discussed, including how to optimally design training opportunities in exposure therapy.
