Characteristics associated with attitudes and behaviors towards mask wearing during the COVID-19 pandemic: The Trojan Pandemic Response Initiative.

BACKGROUND: Attitudes and behaviors towards mask wearing may influence the ability to reduce transmission of COVID-19 and other diseases. METHODS: University students, staff, and faculty (N = 9653) responded to an email invitation to complete electronic surveys (November 2021 and April 2022). Surveys included 19 items measuring attitudes and behaviors towards mask wearing from the Understanding America Study. Linear mixed models including variables for sex, age group, division, race and ethnicity, political affiliation, and history of COVID-19, were used to estimate the mean difference of the mean score for attitudes and behavior between Time 1 (November 2021) and Time 2 (April 2022). RESULTS: Participants were mostly female (62.1%), students (70.6%), White (39.5%) and Asian (34.7%). More than half identified their political affiliation as Democrat (65.5%). Characteristic variable-by-time interactions for difference in mean mask attitude scores difference were significant at Time 1 (T1) and Time 2 (T2) between Black and White participants (B = 0.18 (0.05), 95% CI: 0.07, 0.28, p = 0.001), Asian and White participants (B = 0.07 (0.02), 95% CI: 0.03-0.12, p = 0.001), participants with self-reported history of COVID-19 and no history of COVID-19 (B= -0.13 (0.02), 95% CI: -0.07, -0.18, p < 0.0001), females and males (B = 0.07 (0.02), 95% CI: 0.03, 0.11, p = 0.001), Republicans and Democrats (B= -0.18 (0.04), 95%CI: -0.26, -0.10, p < 0.0001) and Independents and Democrats (B= -0.10 (0.03), 95%CI: -0.15, -0.05, p < 0.0001). Mean difference in mean scores for mask behaviors at Time and Time 2 were significant between participants with COVID-19 and participants who did not have COVID-19 (B= -0.12 (0.04), 95% CI: -0.19, -0.04, p = 0.004), students compared to faculty and staff (B=-0.22 (0.05), -0.32, -0.12, p < 0.0001), between Republicans and Democrats (B-= -0.16 (0.07), 95% CI: -0.28, -0.03, p = 0.020, and between Independents and Democrats (B=-0.08 (0.04), 95% CI: -0.16, -0.002, p = 0.04). CONCLUSION: Race and ethnicity, political affiliation, and division may affect attitudes and behaviors in mask wearing. Further investigation into how characteristics influence public health measures such as mask wearing is needed to contain the spread of the COVID-19 virus, other infectious diseases, and future pandemics.

Surveillance of Severe Acute Respiratory Syndrome Coronavirus 2 and Variants Using Digital Droplet Polymerase Chain Reaction at a Large University and Healthcare System in California.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with different infectivity, transmission potential, and morbidity change the characteristics of local epidemics and affect vaccine effectiveness. As part of the University of Southern California COVID-19 Pandemic Research Center's efforts to understand, control, and inform local community on coronavirus disease 2019 (COVID-19), we implemented a SARS-CoV-2 surveillance program among students, employees, and USC Keck Medical Center patients. We present the epidemiology and distribution of SARS-CoV-2 and its variants among the population. Methods: We used digital droplet reverse-transcriptase polymerase chain reaction (PCR) to analyze in real-time remnant SARS-CoV-2 PCR-positive saliva specimens stored at the USC Keck Medicine laboratory between September 2020 and April 2022. Samples were tested for the original strain (A20) and 9 SARS-CoV-2 variants: α(B.1.1.7, Q.1-Q.8), ß(B.1.351, B.1.351.2, B.1.351.3), γ(P.1, P.1.1, P.1.2), δ(B.1.617.2), δ+(or δ417N), ε(B.1.427 and B.1.429), η(B.1.525), λ(C.37) and ο(B.1.1.529, ΒΑ.1, BA.2). We reviewed deidentified health information from positive cases including demographics, history of COVID-19 (eg, symptoms, hospitalizations, and repeat infections), and COVID-19 vaccination status. Results: We reviewed 1169 cases and determined the variant type of 482 specimens: 77 specimens were original strain, 119 "Delta", 165 "Omicron". The original strain was detected during the third and fourth quarters of 2020. The Delta variant appeared during the second quarter of 2021, whereas Omicron appeared in the fourth quarter of 2021. Conclusions: Prospectively tracking SARS-CoV-2 variants in a university population and a hospital system, utilizing a low-cost, high-throughput PCR assay, was feasible. Local variant monitoring remains important to inform prevention and control efforts among university and clinical settings.

Trust in science and scientists among university students, staff, and faculty of a large, diverse university in Los Angeles during the COVID-19 pandemic, the Trojan Pandemic Response Initiative.

BACKGROUND: Mistrust in science and scientists may adversely influence the rate of COVID-19 vaccination and undermine public health initiatives to reduce virus transmission. METHODS: Students, staff and faculty responded to an email invitation to complete an electronic survey. Surveys included 21-items from the Trust in Science and Scientists Inventory questionnaire. Responses were coded so higher scores indicated a higher trust in science and scientists, A linear regression model including sex, age group, division, race and ethnicity, political affiliation, and history of COVID-19, was used to determine variables significantly associated with trust in science and scientists scores at the p < 0.05 level. RESULTS: Participants were mostly female (62.1%), Asian (34.7%) and White (39.5%) and students (70.6%). More than half identified their political affiliation as Democrat (65%). In the final regression model, all races and ethnicities had significantly lower mean trust in science and scientists scores than White participants [Black ([Formula: see text]= -0.42, 95% CI: -0.55, -0.43, p < 0.001); Asian ([Formula: see text]= -0.20, 95% CI: -0.24, -0.17, p < 0.001); Latinx ([Formula: see text]= -0.22, 95% CI: -0.27, -0.18, p < 0.001); Other ([Formula: see text]= -0.19, 95% CI: -0.26, -0.11, p < 0.001)]. Compared to those identifying as Democrat, all other political affiliations had significantly lower mean scores. [Republican ([Formula: see text] =-0.49, 95% CI: -0.55, -0.43, p < 0.0001); Independent ([Formula: see text] =-0.29, 95% CI: -0.33, -0.25, p < 0.0001); something else ([Formula: see text] =-0.19, 95% CI: -0.25, -0.12, p < 0.0001)]. Having had COVID-19 ([Formula: see text]= -0.10, 95% CI: -0.15, -0.06, p < 0.001) had significantly lower scores compared to those who did not have COVID-19. CONCLUSION: Despite the setting of a major research University, trust in science is highly variable. This study identifies characteristics that could be used to target and curate educational campaigns and university policies to address the COVID19 and future pandemics.

Correlates of COVID-19 vaccination status among college students.

Objectives: Despite the widespread availability of COVID-19 vaccines in the United States, vaccine hesitancy remains high among certain groups. This study examined the correlates of being unvaccinated among a sample of students attending a single university (N = 2900) during the spring and summer of 2021, when the campus had been closed for over a year and students were preparing to return to in-person learning. Methods: Students responded to an email invitation and completed electronic surveys. Results: In multivariable logistic regression analyses, students were more likely to be unvaccinated if they were African American, identified with any political affiliation other than Democrat, were undergraduates or international students, had not traveled outside the Los Angeles during the pandemic, and/or had previously been ill with COVID-19. Conclusion: Findings indicate that culturally resonant educational interventions, and possibly vaccine requirements, are needed to promote vaccination among university students.

COVID-19 booster vaccine attitudes and behaviors among university students and staff in the United States: The USC Trojan pandemic research Initiative.

Although authorized mRNA COVID-19 vaccines (BNT162b2 by BioNTech/Pfizer and mRNA-1273 by Moderna) significantly reduce morbidity and mortality, recent evidence suggests that immunity wanes over time, and that a booster dose could further reduce COVID-19 transmission and severe illness. However, research examining attitudes on booster willingness in diverse populations is needed. This study examined COVID-19 booster vaccine attitudes and behaviors among university students and staff in the fall of 2021. In our sample, 96.2% of respondents indicated willingness to get a COVID-19 booster shot at least once per year. In both bivariate and multivariate analyses higher trust in science was associated with having higher odds of booster willingness. Those who identify as Black, on average, reported trusting science less than other racial/ethnic groups. Our findings demonstrate high willingness to receive a COVID-19 booster shot and highlight the importance of educational messages and initiatives that focus on building trust in science to increase willingness to get the COVID-19 booster. More research is needed to better understand the impact of cultural beliefs on booster willingness and vaccine hesitancy. This understanding will help determine what messages and populations to target to increase booster willingness in the future.

Characteristics associated with COVID-19 vaccination status among staff and faculty of a large, diverse University in Los Angeles: The Trojan Pandemic Response Initiative.

Objective: This study examined characteristics associated with being unvaccinated among a sample of university staff and faculty prior to university campus reopening for in-person learning in 2021. Methods: Staff and faculty responded to an email invitation to complete an online survey. Survey questions included demographic data (race/ethnicity, age, sex), COVID-19 knowledge and behaviors, employment specific data including division and subdivision (healthcare vs. non-healthcare related division); and self-reported vaccination status. A multivariable logistic regression analysis was performed to determine significant characteristics associated with the likelihood of being unvaccinated for COVID-19. Results: Participants identifying as Asian and Asian American (aOR = 1.44, 95% CI: 1.06, 1.96), Hispanic/Latinx (aOR = 1.73, 95% CI: 1.21, 2.49) or Multicultural/Other (aOR = 1.72, 95% CI: 1.24, 2.38) had greater odds of being unvaccinated compared to Non-Hispanic White participants. Other characteristics associated with greater likelihood of being unvaccinated included working as a university staff member (vs. faculty) (aOR = 1.69, 95% CI: 1.24. 2.30), decrease in income (aOR = 1.34, 95% CI:1.05, 1.71), inability to work remotely (aOR = 1.48, 95% CI:1.13, 1.93) and not traveling outside of the Los Angeles area (aOR = 1.46, 95% CI: 1.16, 1.83). Political affiliation as an Independent (aOR = 1.39, 95% CI:1.04, 1.85) or as something else (aOR = 3.84, 95% CI: 2.72, 5.41) were more likely to be unvaccinated compared to participants identifying as Democrat. Conclusions: Several factors associated with racial and social disparities may delay the uptake of COVID-19 vaccination. This study highlights the need for targeted educational interventions to promote vaccination among university staff and faculty.

Identity mediates inequity and flourishing among racially minoritized and international undergraduate college students.

OBJECTIVE: Racially minoritized individuals can simultaneously experience both oppression and flourishing (ie, positive mental health). This study examines identity connection as a mediator of this relationship. PARTICIPANTS: Undergraduates at a large, private university (n = 771), 59.4% racially minoritized American or international (RMA/I). METHODS: Measures included perception of value, perception of fair/equitable treatment, identity centrality (ie, significance of racial/ethnic identity), identity exploration, and flourishing. Structural equation models compared RMA/I vs. white American students. RESULTS: Among RMA/I students, flourishing was predicted by perception of value and identity centrality; identity centrality was positively predicted by perception of value and negatively predicted by perception of fair/equitable treatment. Among white American students, only perception of value predicted flourishing. CONCLUSIONS: Identity centrality mediated the relationship between fair/equitable treatment and flourishing among these minoritized undergraduate students, supporting theory that identity may be formed in response to oppression.

Human papillomavirus and Chinese international students in the United States: attitudes, knowledge, vaccination trends, healthcare behaviors, and sexual activity.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the world, with the ability to cause external genital warts and cancers. The HPV vaccine, first released in the United States of America (USA) in 2006, has been shown to protect against the highest risk HPV strains responsible for the majority of HPV-related cancers. In mainland China, the HPV vaccine was only recently approved in 2016 and is therefore not readily available. As a result, Chinese international students (CIS) studying in the USA continue to have low HPV vaccination rates. This study completed in person and online surveying of 396 CIS at a large Southern California university, with the goal of better understanding CIS knowledge and awareness of HPV disease, vaccination and healthcare behaviors, and sexual activity. Among participants, the reported HPV vaccination rate was 61% (females: 85%; males: 32%). HPV vaccination was significantly correlated with a past visit to the on-campus student health center, having university-sponsored student health insurance, higher self-perceived HPV knowledge, and increased willingness to pay for vaccination. A large portion of participants portrayed low levels of sexual activity, which suggests that CIS can take advantage of catch-up HPV vaccination recommendations through 26 years of age. The results of this study can be used to inform policy initiatives, particularly at the campus level, that attempt to improve HPV vaccination rates amongst CIS.

A Cross-Sectional Study Examining the Seroprevalence of Severe Acute Respiratory Syndrome Coronavirus 2 Antibodies in a University Student Population.

PURPOSE: The aim of the study was to determine the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in a university student population. METHODS: This was a cross-sectional survey study based on the World Health Organization population-based seroepidemiological investigational protocol for SARS-CoV-2 conducted between April 29, 2020, and May 8, 2020, examining SARS-CoV-2 antibody prevalence among 790 university students in Los Angeles, CA. Participants completed a questionnaire on potential risk factors before blood sampling. Samples were analyzed using the EUROIMMUN Anti-SARS-CoV-2 ELISA (IgG) for the qualitative detection of IgG class antibodies to SARS-CoV-2 in human serum or plasma. RESULTS: The estimated prevalence of SARS-CoV-2 antibody was 4.0% (3.0%, 5.1%). Factors associated with having a positive test included history of anosmia and/or loss of taste (95% CI: 1.4-9.6). A history of respiratory symptoms, with or without fever, was not associated with a positive antibody test. CONCLUSIONS: Prevalence of SARS-CoV-2 antibodies in the undergraduate and graduate student university population was similar to community prevalence.

Gene co-expression networks in peripheral blood capture dimensional measures of emotional and behavioral problems from the Child Behavior Checklist (CBCL).

The U.S. National Institute of Mental Health (NIMH) introduced the research domain criteria (RDoC) initiative to promote the integration of information across multiple units of analysis (i.e., brain circuits, physiology, behavior, self-reports) to better understand the basic dimensions of behavior and cognitive functioning underlying normal and abnormal mental conditions. Along those lines, this study examined the association between peripheral blood gene expression levels and emotional and behavioral problems in school-age children. Children were chosen from two age- and sex-matched groups: those with or without parental reports of any prior or current psychiatric diagnosis. RNA-sequencing was performed on whole blood from 96 probands aged 6-12 years who were medication-free at the time of assessment. Module eigengenes were derived using weighted gene co-expression network analysis (WGCNA). Associations were tested between module eigengene expression levels and eight syndrome scales from parent ratings on the Child Behavior Checklist (CBCL). Nine out of the 36 modules were significantly associated with at least one syndrome scale measured by the CBCL (i.e., aggression, social problems, attention problems, and/or thought problems) after accounting for covariates and correcting for multiple testing. Our study demonstrates that variation in peripheral blood gene expression relates to emotional and behavioral profiles in children. If replicated and validated, our results may help in identifying problem or at-risk behavior in pediatric populations, and in elucidating the biological pathways that modulate complex human behavior.

Initial Responsiveness to Reward Attainment and Psychopathology in Children and Adults: An RDoC Study.

The Research Domain Criteria (RDoC) initiative of the National Institute of Mental Health (NIMH) established a dimensional framework for understanding psychiatric constructs. Initial Responsiveness to Reward Attainment (IRRA) was identified as a dimensional construct relevant to several psychiatric disorders. The current study aimed to (1) examine IRRA as a predictor of psychopathology and impairment in children and their parents, and (2) examine the potential effects of sex and ancestry on the relationship between IRRA and psychopathology. Participants included 1127 children ages 6 to 12, and 1018 of their parents. Parents and children completed self-report measures of IRRA. Psychopathology and impairment were measured using self-report for adults, and parent-report and semi-structured interview for children. In adults, IRRA was significantly, but modestly, related to adaptive functioning. In children, IRRA was significantly, but modestly, related to overall, school, spare time, home, and peer functioning. Findings suggest IRRA may be a helpful construct for understanding adaptive functioning in adults and children, however it may be less helpful for understanding specific dimensions of psychopathology. Additionally, ancestry should be taken into consideration when examining how IRRA relates to psychopathology and functioning.

Effort valuation and psychopathology in children and adults.

BACKGROUND: The Research Domain Criteria initiative was launched by the US National Institute of Mental Health to establish a multi-level framework for understanding psychological constructs relevant to human psychiatric disorders, and identified 'effort valuation/willingness to work' as a clinically useful construct worthy of further study. This construct encompasses the processes by which the cost(s) of obtaining an outcome are calculated, and the tendency to overcome response costs to obtain a reinforcer. The current study aims to examine effort valuation as a correlate of psychopathology in children and adults, and the moderating effects of sex on this relationship. METHODS: Participants were 1215 children aged 6-12 and their parents (n = 1044). All participants completed the Effort Expenditure for Rewards Task as a measure of effort expenditure. Child psychopathology was measured via the Child Behavior Checklist, while adult psychopathology was measured via the Adult Self Report. Additionally, the Social Adjustment Inventory for Children and Adolescents and Injury Behavior Checklist were used to examine child social impairments/problem behaviors. RESULTS: In children, significant interactions between reward sensitivity and sex were observed in association with anxiety and thought problems, specifically at low reward sensitivity levels. In adults, main effects of effort expenditure were seen in drug and alcohol abuse, where higher effort was associated with higher degrees of abuse. CONCLUSIONS: These results establish effort valuation as a relevant psychological construct for understanding psychopathology, but with different profiles of associated psychopathology across sex in children and adults.

Demographic differences in response rates for PHQ9 in a university student population.

OBJECTIVE: To examine differences in complete response rates for depression screening questions based on demographic characteristics. METHODS: Cross-sectional study examining associations between demographic characteristics and completely responding depression-screening questions. PARTICIPANTS: "Healthy Minds Study" data, collected in a public University in February 2016, where 7,326 students participated. RESULTS: women (AOR: 0.69; 95% CI =0.57-0.83) and gay/lesbian students (AOR: 0.24; 95% CI =0.10-0.60) had better complete response rates. Non-US (AOR: 1.46; 95% CI =1.03-2.07), black (AOR: 3.32; 95% CI =1.92-5.77), and Middle-Eastern students (AOR: 3.73; 95% CI =1.73-8.02) had lower complete response rates. CONCLUSIONS: Our study shows sex, gender, citizenship, and race categories have significant differences in complete response rates for the outcome. Our findings have several implications; including recognizing interventions for depression based on responders may not target those that tend to be "partial-responders". Efforts in survey design, recruiting and completion of surveys should be maximized.

Meningococcal serogroup B outbreak response University of Wisconsin-Madison.

A meningococcal serogroup B (MenB) outbreak at a large public university prompted an emergency response to immunize undergraduates. OBJECTIVE: To report on a successful meningococcal serogroup B (MenB) vaccine clinic response at a large public university. METHODS: We assembled the team leaders to write this case report. RESULTS: Activation of the emergency plan and points of dispensing required cooperation of many units on campus under the leadership of university health officials with support from Centers for Disease Control and Prevention, state division of public health and the city-county health department. Significant efforts to provide consistent messages to students and parents regarding the outbreak and the availability of the MenB vaccines were made. Volunteers were recruited to staff the clinics alongside university healthcare providers. Over 22,000 doses of vaccine were administered. CONCLUSION: We report our experience and lessons learned which may be helpful to universities in preventing and responding to disease outbreaks.

A pilot community-based intensive smoking cessation intervention in African Americans: feasibility, acceptability and early outcome indicators.

Few intensive and community-based smoking cessation treatment programs have been designed for African-American smokers, a group who experiences numerous health disparities associated with cigarette smoking. The purpose of this study was to examine the feasibility, acceptability and biochemically verified early outcome indicators in a community-based comprehensive smoking cessation program in 50 urban, low- and middle-income African-American smokers. The intervention was an intensive six-session group program delivered in the community and a one-month supply of the transdermal nicotine patch. Results showed 74% of enrolled participants completed the program and 51% of participants were highly adherent to patch use guidelines. Intent-to-treat analyses revealed that 34% of participants were biochemically confirmed as having quit smoking at one month post quit date. Smoking urges and depressive symptoms also declined significantly during the first month. At three- and six-month follow-up, biochemically confirmed quit rates were 22% and 18%, respectively. Adherence to nicotine patch use, higher ratings of the perceived helpfulness of self-monitoring tasks (wrap sheets) and lower depression scores at baseline all significantly predicted quitting success during the first month of treatment (all p's<0.05). Larger studies are warranted to examine targeted treatment elements and individual difference factors to enhance cessation outcomes in African-American smokers.

Bulimia nervosa in adolescents: a disorder in evolution?

BACKGROUND: There are few reports that describe the manifestation of bulimia nervosa (BN) among adolescents. Moreover, none make reference to the comparative clinical manifestation of adolescent BN and adolescent anorexia nervosa. Nor are any reports available of how distinct partial-syndrome BN cases are from those that meet full diagnostic criteria for BN. OBJECTIVES: To describe 3 groups of adolescents, those with a full-syndrome eating disorder (BN and anorexia nervosa) or partial-syndrome BN, and to compare these groups along demographic, general psychopathology, and eating disorder variables. DESIGN: The study population included 120 adolescents with eating disorders who were initially seen at The University of Chicago Eating Disorders Program, Chicago, Ill, for treatment. All participants completed an assessment prior to treatment. MEASURES: Weight and height were obtained from all participants. Participants also completed a baseline demographic questionnaire (eg, menstrual status, ethnicity, family status), Beck Depression Inventory, Rosenberg Self-Esteem Scale, and the Eating Disorder Examination. RESULTS: Partial-syndrome BN cases are clinically quite similar to their full-syndrome counterparts. Only objective binge eating episodes and purge frequency distinguished BN and partial-syndrome BN cases. Anorexia nervosa cases, on the other hand, were quite distinct from BN and partial-syndrome BN cases on almost all variables. CONCLUSION: Early recognition and swift treatment of eating disorders in adolescents, regardless of whether a diagnostic threshold is met, are imperative because they will lead to early intervention thereby potentially improving eating disorder recovery rates.
