Insomnia among college students: A bibliometric analysis from 2003 to 2022.

BACKGROUND: Insomnia has become a common health problem in modern society, especially among college students. The purpose of this study was to analyze the research status, research hotspots and frontier trends of insomnia among college students over the past 20 years. METHODS: VOSviewer 1.6.19 and CiteSpace 6.2 were used. R4: This study conducts a bibliometric and visualization analysis of the annual publications, authors, countries/regions, institutions, categories, journal/literature cocitations and keywords related to insomnia among college students in the Web of Science (WoS) core collection from 2003 to 2022. RESULTS: A total of 590 studies were included, and the number of studies on insomnia among college students has steadily increased over the last 20 years. The authors of high yield are represented by Taylor DJ and Miller MB. The countries/regions with high yields were the USA and China. The institutions of high yield were King Saud University and Southern Medical University. Its research fields were mainly Clinical Neurology, Psychiatry and Neurosciences. Mental health and insomnia, sleep quality and the impact of coronavirus disease 2019 (COVID-19) on insomnia are current research hotspots. Future research could focus on predicting the chronotype and physical activity of insomnia students. CONCLUSION: Through bibliometric and visualization analysis, this study investigated insomnia among college students over the past 20 years and preliminarily revealed the findings of coauthors and institutions. This study provides a general understanding of the research hotspots and frontier trends of insomnia among college students and provides some references for future research.

Risk of eating disorders in Mexican university students.

OBJECTIVE: To determine the distribution of the risk of developing an eating disorder, other psychological variables, body mass index (BMI) and physical activity in Mexican university students. The second aim was to determine the association between the risk of developing an eating disorder and all variables by sex. DESIGN: A cross-sectional study was carried out. SETTING: The Health Sciences Institute and the Agricultural Sciences Institute within the Autonomous University of Hidalgo State, Mexico. PARTICIPANTS: 395 university students (65 % women) aged 18 to 29. ANALYSIS: Descriptive, correlational and binary regression model. RESULTS: The risk of developing an eating disorder (moderate and high) was 37.3 % for women and 32.6 % for men. A logistic regression analysis of women showed that thin-ideal internalization (12.9 times), BMI (3.5 times) and inactivity (2.6 times) increased the risk of developing an eating disorder. In men, the drive for muscularity (7.5 times) and BMI (2.3 times) increased the risk. CONCLUSION AND IMPLICATIONS: The variables associated with the risk of developing an eating disorder differed by sex, except for BMI, which increased the risk in both sexes. Findings should be considered in the design of future interventions to prevent the risk of eating disorders and associated factors.

The impact of critical thinking skills on student pharmacist GPA at a historically Black university.

INTRODUCTION: Limited information is available regarding whether malleable factors such as critical thinking skills are associated with academic performance among underrepresented minority pharmacy students. This study assessed the relationship between critical thinking skills and grade point average (GPA) among pharmacy students attending a Historically Black College. METHODS: A cross sectional study design was utilized to evaluate the association between student's GPA and critical thinking skills. Demographic data and GPA were abstracted from student records. The health sciences reasoning test with numeracy was administered to pharmacy students at Howard University during the 2017 to 2018 academic year. Critical thinking scores were classified as weak, moderate, or strong/superior. A one way analysis of variance was conducted to ascertain if the average GPA differed based on critical thinking skills category. A multiple linear regression analysis was conducted to determine whether student's critical thinking skill category was associated with the cumulative GPA after accounting for other factors. RESULTS: Among 217 students, the mean GPA among students with a weak critical thinking skills score (3.22 ± 0.40) was lower compared to students with a strong/superior score (3.39 ± 0.33) with a p-value of 0.029. After adjusting for other factors, a strong/superior critical thinking skills score was associated with a higher GPA (p-value = 0.024) in comparison to weak critical thinking skills. CONCLUSION: Stronger critical thinking skills scores are associated with better academic performance among underrepresented minority pharmacy students.

Physical activity levels in various university majors amidst the COVID-19 pandemic: a comparative study / Nivel de actividad física en varias carreras universitarias en medio de la pandemia de COVID-19: Un estudio comparativo / Níveis de atividade física em várias carreiras universitárias em meio à pandemia de COVID-19: Um estudo comparativo

This study determined levels of physical activity in students by comparing them based on gender, faculty, and major among university students during the Covid-19 pandemic. The research followed a quantitative approach with a descriptive-comparative design. The study was conducted once per student, with the participation of 582 students of both genders. The International Physical Activity Questionnaire (IPAQ) was administered to the students using Google Forms, distributed through their institutional emails. The collected data were analyzed using the statistical software SPSS V.22.0. The independent samples t-test was employed to compare the energy expenditure between males and females, along with Cohen's d statistic to assess the effect size. Prior to these analyses, the Kolmogorov-Smirnov normality test and Levene's test were conducted. Results were considered significant when the p-value was <0.05. The findings indicate that males allocate more time to work than females. Additionally, it was observed that males exhibit a higher level of physical activity than females within the engineering field. Lastly, majors with the highest levels of physical activity per week were Physical Education and Nutrition. These outcomes shed light on the reality of physical activity levels among Chilean university students based on faculty and major. University authorities should consider promoting physical activity programs, particularly emphasizing women and majors such as engineering, architecture, and mathematics, which have shown lower levels of physical activity.

Este estudio tiene un enfoque de investigación cuantitativa con diseño descriptivo-comparativo. Este estudio se aplicó una sola vez por estudiante contando con la participación de 582 estudiantes de ambos sexos. A los estudiantes se les aplicó el cuestionario Internacional de Actividad Física (IPAQ) mediante Google forms haciéndoselos llegar sus correos institucionales. Los datos obtenidos se analizaron en el programa estadístico SPSS V.22.0. Se utilizo la prueba estadística T-student para muestras independientes para comparar el coste energético entre hombres y mujeres, además del estadístico d de Cohen para evaluar el tamaño del efecto. Antes de realizar estas evaluaciones se realizó la prueba de normalidad Kolmogorov Smirnov y prueba de Levene. Se consideraron resultados significativos cuando el valor de p fue <0.05. Los resultados indican que los hombres destinan mayor tiempo a trabajar que las mujeres, además se encontró que los hombres poseen mayor nivel de actividad física que las mujeres en ingeniería. Finalmente, los estudiantes de las carreras con mayor nivel de actividad física a la semana fueron Educación física y nutrición. Estos resultados dan cuenta de la realidad en universitarios chilenos respecto al nivel de actividad física por facultad y por carrera. Las autoridades universitarias deberían promover programas de actividad física enfatizando en mujeres y en carreras de ingeniería, arquitectura y matemática que han mostrado menores niveles de actividad física.

How social media usage affects psychological and subjective well-being: testing a moderated mediation model.

BACKGROUND: A growing body of literature demonstrates that social media usage has witnessed a rapid increase in higher education and is almost ubiquitous among young people. The underlying mechanisms as to how social media usage by university students affects their well-being are unclear. Moreover, current research has produced conflicting evidence concerning the potential effects of social media on individuals' overall well-being with some reporting negative outcomes while others revealing beneficial results. METHODS: To address the research gap, the present research made an attempt to investigate the crucial role of social media in affecting students' psychological (PWB) and subjective well-being (SWB) by testing the mediating role of self-esteem and online social support and the moderation effect of cyberbullying. The data in the study were obtained from a sample of 1,004 college students (483 females and 521 males, Mage = 23.78, SD = 4.06) enrolled at 135 Chinese universities. AMOS 26.0 and SPSS 26.0 as well as the Process macro were utilized for analyzing data and testing the moderated mediation model. RESULTS: Findings revealed that social media usage by university students was positively associated with their PWB and SWB through self-esteem and online social support, and cyberbullying played a moderating role in the first phase of the mediation process such that the indirect associations were weak with cyberbullying reaching high levels. CONCLUSION: These findings highlight the importance of discerning the mechanisms moderating the mediated paths linking social media usage by young adults to their PWB and SWB. The results also underline the importance of implementing measures and interventions to alleviate the detrimental impacts of cyberbullying on young adults' PWB and SWB.

Factors Associated With Binge Eating Among Chinese University Students in Hong Kong.

Binge eating (BE), defined as uncontrolled overconsumption of food, is associated with poorer health status. We aimed to characterize the factors associated with BE among Chinese college students. University students from two universities in Hong Kong (n = 267) completed an anonymous online questionnaire that contained background questions, the Binge Eating Disorder Screener-7, Depression, Anxiety, and Stress Scales-21 (DASS-21), and Adolescent Lifestyle Questionnaire (ALQ) between June and August 2022. Multiple logistic regression and two-sample independent t-test were conducted to test the association of study variables with BE. In this university sample, 36.8% of males and 21.4% of females were classified as engaging in BE in the last three months. BE was statistically significantly associated with higher body mass index (BMI), more depressive symptoms, and lower ALQ nutrition scores among males and lower BMI, more depressive, anxiety, and stress symptoms among females. BE was significantly associated with various factors in both male and female university students in Hong Kong; thereby, university health promotion programs should include the management of BE. BE should be a prominent focus of health promotion interventions in conjunction with mental health promotion in the region.

The association between academic performance indicators and lifestyle behaviors among Kuwaiti college students.

BACKGROUND: Lifestyle behaviors are developed during young adulthood and carried through life. Accordingly, early detection of unhealthy behaviors can help prevent the increase in non-communicable diseases in the population. College students are an especially vulnerable group who, upon entering a new environment, tend to engage in unhealthy behaviors. OBJECTIVE: The present study aims to evaluate the lifestyle behaviors of Kuwaiti college students and their association with markers of academic achievements. METHODS: One thousand two hundred fifty-nine students participated in the present study and answered an online questionnaire pertaining to their sociodemographic status, academic performance indicators, body weight and height, and lifestyle behaviors. Data were collected from November 2020 to February 2021. RESULTS: Results of the present study showed that obesity was significantly more prevalent among male participants than among females even though males were more physically active. Alternatively, females had a greater grade point average in college, slept more, and had more screen time. Interestingly, we were unable to detect a significant correlation between lifestyle behaviors and academic achievements. CONCLUSION: The observed differences in body mass index between genders may have been attributed to energy intake rather than energy expenditure.

Exploring the Mental Health Challenges and Coping Behaviour of Lesbian, Gay, and Bisexual Students at an Institution of Higher Learning.

The South African university community is predominantly heterosexual, which fosters stigmatisation and discrimination against LGBTQI students despite the efforts to create conditions where LGBTQI students can succeed academically, socially, and personally. The study aimed to explore and describe the challenges experienced by LGBTQI students and their mental well-being as well as the coping behaviours adopted in a university in South Africa. This was accomplished using a descriptive phenomenological approach. A snowballing sampling method was used to select ten students who identified themselves as gay, lesbian, and bisexual (LGB). Semi-structured one-on-one interviews were conducted, and data were analysed thematically. The students perceived character defects stigma from fellow students and lecturers in and out of class. The mental health challenges experienced included a diminished sense of safety, lack of a sense of belonging, low self-esteem, and acting out of character. As a result, confrontation, passive withdrawal, and active dependent behaviour were utilised as different types of coping behaviour. The LGB students were subjected to stigma that negatively affected their mental health. Therefore, creating awareness about the rights of LGBTQI students to education, safety, and self-determination is recommended.

Does lower use of academic affiliation by university faculty in top U.S. newspapers contribute to misinformation about abortion?

BACKGROUND: University faculty are considered trusted sources of information to disseminate accurate information to the public that abortion is a common, safe and necessary medical health care service. However, misinformation persists about abortion's alleged dangers, commonality, and medical necessity. METHODS: Systematic review of popular media articles related to abortion, gun control (an equally controversial topic), and cigarette use (a more neutral topic) published in top U.S. newspapers between January 2015 and July 2020 using bivariate analysis and logistic regression to compare disclosure of university affiliation among experts in each topic area. RESULTS: We included 41 abortion, 102 gun control, and 130 smoking articles, which consisted of 304 distinct media mentions of university-affiliated faculty. Articles with smoking and gun control faculty experts had statistically more affiliations mentioned (90%, n = 195 and 88%, n = 159, respectively) than abortion faculty experts (77%, n = 54) (p = 0.02). The probability of faculty disclosing university affiliation was similar between smoking and gun control (p = 0.73), but between smoking and abortion was significantly less (Ave Marginal Effects - 0.13, p = 0.02). CONCLUSIONS: Fewer faculty members disclose their university affiliation in top U.S. newspapers when discussing abortion. Lack of academic disclosure may paradoxically make these faculty appear less 'legitimate.' This leads to misinformation, branding abortion as a 'choice,' suggesting it is an unessential medical service. With the recent U.S. Supreme Court landmark decision, Dobbs v. Jackson Women's Health Organization, and subsequent banning of abortion in many U.S. states, faculty will probably be even less likely to disclose their university affiliation in the media than in the past.

Síndrome de Burnout en estudiantes y profesionales de la Carrera de Terapia Ocupacional de la Universidad Central del Ecuador / Burnout syndrome in students and professionals of the Occupational Therapy Career of the Central University of Ecuador

Introducción: El síndrome de Burnout es un fenómeno muy común en los diferentes am-bientes de trabajo, pero estudios de prevalencia en profesionales y estudiantes de terapia ocupacional son limitados.Objetivo: Establecer la presencia de síndrome de Burnout en estudiantes y profesionales de los centros de práctica de la carrera de Terapia Ocupacional de la Universidad Central del Ecuador.Material y métodos: Diseño de estudio observacional, descriptivo, de corte transversal, en 177 estudiantes de la carrera de Terapia Ocupacional y 35 profesionales en el área que laboran en los centros de práctica vinculados a la práctica preprofesional. En cada suje-to se determinó agotamiento emocional, despersonalización y falta de realización personal mediante la Escala Maslach Burnout Inventory; la presencia de nivel alto en las subescalas agotamiento emocional y despersonalización y nivel bajo en realización personal define sín-drome de Burnout. Se calculó la prevalencia del síndrome en estudiantes y profesionales y la correlación con años de ejercicio laboral y sexo.Resultados: El 2.9 % (1/35) de los profesionales y 4.5 % (8/177) de estudiantes presentaron síndrome Burnout, el que se relacionó con las variables ambientales personales incluidas en la escala de Maslach. Del 45.83% al 82.14 % de estudiantes presentaron niveles bajos de cansancio emocional y despersonalización, mientras que, del 37.14 % al 52.94 %, presenta-ron niveles medios de realización personal.Conclusión: La prevalencia del síndrome de Burnout es baja en los profesionales y en los estudiantes de la carrera de Terapia Ocupacional que hacen prácticas preprofesionales en diferentes instituciones.

Introduction: Burnout syndrome is a very common phenomenon in different work environments; however, prevalence studies in occupational therapy professionals and students are limited.Objective: To establish the presence of Burnout syndrome in students and professionals at practice centers of the Occupational Therapy Career from Universidad Central del Ecuador.Material and methods: Cross-sectional, descriptive, observational study design in 177 stu-dents belonging to the Occupational Therapy Career and 35 professionals in the area who work in the practice centers linked to pre-professional practice. Emotional exhaustion, de-personalization and lack of personal fulfillment were determined in each subject using the Maslach Burnout Inventory Scale; the presence of a high level in the emotional exhaustion and depersonalization subscales and a low level of personal fulfillment defines Burnout syn-drome. The prevalence of Burnout syndrome in students and professionals and the correla-tion with years of work practice and gender were calculated.Results: 2.9% (1/35) of the professionals and 4.5% (8/177) of the students presented Bur-nout syndrome, which was related to the personal environmental variables included in the Maslach scale. From 45.83% to 82.14% of students presented low levels of emotional fati-gue and depersonalization; on the other hand, from 37.14% to 52.94% presented average levels of personal fulfillment.Conclusion: The prevalence of Burnout syndrome is low as in professionals as in students of the Occupational Therapy Career who do pre-professional practices in different institutions.

Fertility Intentions, Parenting Attitudes, and Fear of Childbirth among College Students in China: A Cross-Sectional Study.

STUDY OBJECTIVE: This study aimed to investigate the current situation regarding fertility intentions, parenting attitudes, and fear of childbirth among college students in mainland China and the factors related to these variables. DESIGN: A cross-sectional study SETTING: Colleges across China PARTICIPANTS: Five hundred and eighty-three college students attending regular institutions of higher education MAIN OUTCOME MEASURES: Fertility intentions and fear of childbirth were measured using the Swedish Fertility Awareness Questionnaire and the Childbirth Fear Prior to Pregnancy scale. RESULTS: Only 38.8% of participants expressed their willingness to have children, and there was a significant difference between male and female students (P < .02). Males regarded having children as more important (P < .01), and females were more concerned about the negative effects of becoming parents, including difficulties in the labor market, having less freedom, and having less money. When deciding whether to have children, factors such as work, economics, and childcare were more important to females. Students who did not want children had higher levels of fear of childbirth than those who wanted children or were unsure (P < .02). CONCLUSIONS: The fertility intentions of college students were not optimistic. In addition to the 2-child Chinese fertility policy, interventions aimed at reducing the cost of raising children, eliminating gender inequality in the workplace, and normalizing childcare institutions might help alleviate conflict between work and childrearing.

Vagal Nerve Stimulation: A Bibliometric Analysis of Current Research Trends.

BACKGROUND: Vagal nerve stimulation (VNS) has become established as an effective tool for the management of various neurologic disorders. Consequently, a growing number of VNS studies have been published over the past four decades. This study presents a bibliometric analysis investigating the current trends in VNS literature. MATERIALS AND METHODS: Using the Web of Science collection data base, a search was performed to identify literature that discussed applications of VNS from 2000 to 2021. Analysis and visualization of the included literature were completed with VOSviewer. RESULTS: A total of 2895 publications were identified. The number of articles published in this area has increased over the past two decades, with the most citations (7098) occurring in 2021 and the most publications (270) in 2020. The h-index, i-10, and i-100 were 97, 994, and 91, respectively, with 17.0 citations per publication on average. The highest-producing country and institution of VNS literature were the United States and the University of Texas, respectively. The most productive journal was Epilepsia. Epilepsy was the predominant focus of VNS research, with the keyword "epilepsy" having the greatest total link strength (749) in the keyword analysis. The keyword analysis also revealed two major avenues of VNS research: 1) the mechanisms by which VNS modulates neural circuitry, and 2) therapeutic applications of VNS in a variety of diseases beyond neurology. It also showed a significant prevalence of noninvasive VNS research. Although epilepsy research appears more linked to implanted VNS, headache and depression specialists were more closely associated with noninvasive VNS. CONCLUSION: VNS may serve as a promising intervention for rehabilitation beyond neurologic applications, with an expanding base of literature over the past two decades. Although epilepsy researchers have produced most current literature, other fields have begun to explore VNS as a potential treatment, likely owing to the rise of noninvasive forms of VNS.

Overweight/obesity in college students: a systematic review / Excesso de peso/obesidade em estudantes universitários: uma revisão sistemática / Sobrepeso/obesidad en estudiantes universitarios: una revisión sistemática

This article aims to characterize the prevalence and the factors associated with overweight/obesity in college students, through a systematic review. For doing so, the PRISMA protocol has been utilized. Articles about overweight/obesity were selected in college students on the databases of the National Library of Medicine (PUBMED), Scientific Electronic Library Online (SciELO), Biblioteca Virtual em Saúde (BVS), Web of Science and Scopus, it was considered the publication period from 2014 to 2019. We found 4,740 articles and 28 met the eligibility criteria. The overweight/obesity prevalence in college students varied from 9.5% to 47.0%. The Odds Ratio was the most used association measure (comparison) in studies. As characteristics that favor overweight/obesity, inadequate diet, income, male gender, low level of physical activity and family history of overweight/obesity are mentioned. The factors associated with protection against overweight/obesity were a healthy diet, regular physical activity and screen time. Finally, this review showed that university students are prone to overweight/obesity, as they have behavioral factors related to inadequate diet, low level of physical activity, income, being male, and sociocultural and family aspects due to a history of overweight/obesity. In counterpart, this review argues that healthy diet and physical activity and reduced screen time represent a health maintenance factor against overweight/obesity.

Quantifying hierarchy and dynamics in US faculty hiring and retention.

Faculty hiring and retention determine the composition of the US academic workforce and directly shape educational outcomes1, careers2, the development and spread of ideas3 and research priorities4,5. However, hiring and retention are dynamic, reflecting societal and academic priorities, generational turnover and efforts to diversify the professoriate along gender6-8, racial9 and socioeconomic10 lines. A comprehensive study of the structure and dynamics of the US professoriate would elucidate the effects of these efforts and the processes that shape scholarship more broadly. Here we analyse the academic employment and doctoral education of tenure-track faculty at all PhD-granting US universities over the decade 2011-2020, quantifying stark inequalities in faculty production, prestige, retention and gender. Our analyses show universal inequalities in which a small minority of universities supply a large majority of faculty across fields, exacerbated by patterns of attrition and reflecting steep hierarchies of prestige. We identify markedly higher attrition rates among faculty trained outside the United States or employed by their doctoral university. Our results indicate that gains in women's representation over this decade result from demographic turnover and earlier changes made to hiring, and are unlikely to lead to long-term gender parity in most fields. These analyses quantify the dynamics of US faculty hiring and retention, and will support efforts to improve the organization, composition and scholarship of the US academic workforce.

Social capital II: determinants of economic connectedness.

Low levels of social interaction across class lines have generated widespread concern1-4 and are associated with worse outcomes, such as lower rates of upward income mobility4-7. Here we analyse the determinants of cross-class interaction using data from Facebook, building on the analysis in our companion paper7. We show that about half of the social disconnection across socioeconomic lines-measured as the difference in the share of high-socioeconomic status (SES) friends between people with low and high SES-is explained by differences in exposure to people with high SES in groups such as schools and religious organizations. The other half is explained by friending bias-the tendency for people with low SES to befriend people with high SES at lower rates even conditional on exposure. Friending bias is shaped by the structure of the groups in which people interact. For example, friending bias is higher in larger and more diverse groups and lower in religious organizations than in schools and workplaces. Distinguishing exposure from friending bias is helpful for identifying interventions to increase cross-SES friendships (economic connectedness). Using fluctuations in the share of students with high SES across high school cohorts, we show that increases in high-SES exposure lead low-SES people to form more friendships with high-SES people in schools that exhibit low levels of friending bias. Thus, socioeconomic integration can increase economic connectedness in communities in which friending bias is low. By contrast, when friending bias is high, increasing cross-SES interactions among existing members may be necessary to increase economic connectedness. To support such efforts, we release privacy-protected statistics on economic connectedness, exposure and friending bias for each ZIP (postal) code, high school and college in the United States at https://www.socialcapital.org .
