Learner experiences of safety at public high schools in three South African townships: Baseline findings from the National School Safety Framework learner surveys.

Background: Despite progressive policies and frameworks on school safety by the Department of Basic Education, safety remains a concern in South African schools. Methods: A cross-sectional descriptive design was employed using the National School Safety Framework (NSSF) 152-question learner survey, exploring perceptions and experiences pertaining to eight safety domains: dangerous objects, drugs and alcohol, bullying, verbal abuse, physical violence, discrimination, sexual violence, and journey to and from school. Grade 9-11 learners from 15 government-funded high schools in the Girls Achieve Power trial in Khayelitsha, Soweto, and Thembisa townships were surveyed (March 2018 - April 2019), sampling 10% of the school population. Data analysis included Principal Component Analysis (PCA), reducing correlated variables into fewer questions, then analysis on a scree plot by calculating eigenvalues; repeated PCA with those that had a minimum eigenvalue of 1 and Cronbach Alpha test for internal reliability. Eleven composite variables were included in the final analysis. Results: In total, 1034 learners completed the NSSF learner survey; 52.9% were female and the mean age was 16 years (SD=1.36). Results show statistically significant associations between four of the 11 composite variables in relation to sex. Over half (55%) of males have experienced peer provocation and relational aggression (p<0.001). Fifty-eight percent of females reported feeling unsafe on their way to and from school (p<0.003). Over half of males reported that their school was not effective in enforcing discipline (p=0.002) while 58% of females noted they could comfortably report any form of experienced or witnessed violence at school, to their educators (p<0.000). Conclusions: Violence continues to be a concern in South African schools. Interventions should work across the ecological model to effectively prevent and reduce violence at school and community levels. Strengthened NSSF implementation is critical to achieving this. We recommend NSSF learner survey adaptations to increase utility and implementation.

High school science fair: School location trends in student participation and experience.

The findings reported in this paper are based on surveys of U.S. high school students who registered and managed their science and engineering fair (SEF) projects through the online Scienteer website over the three years 2019/20, 2020/21, and 2021/22. Almost 2500 students completed surveys after finishing all their SEF competitions. We added a new question in 2019/20 to our on-going surveys asking the students whether their high school location was urban, suburban, or rural. We learned that overall, 74% of students participating in SEFs indicated that they were from suburban schools. Unexpectedly, very few SEF participants, less than 4%, indicated that they were from rural schools, even though national data show that more than 20% of high school students attend rural schools. Consistent with previous findings, Asian and Hispanic students indicated more successful SEF outcomes than Black and White students. However, whereas Asian students had the highest percentage of SEF participants from suburban vs. urban schools- 81% vs. 18%, Hispanic students had the most balanced representation of participants from suburban vs. urban schools- 55% vs. 39%. Differences in students' SEF experiences based on gender and ethnicity showed the same patterns regardless of school location. In the few items where we observed statistically significant (probability < .05) differences based on school location, students from suburban schools were marginally favored by only a few percentage points compared to students from urban schools. In conclusion, based on our surveys results most students participating in SEFs come from suburban schools, but students participating in SEFs and coming from urban schools have equivalent SEF experiences, and very few students participating in SEFs come from rural schools.

School closures significantly reduced arrests of black and latinx urban youth.

BACKGROUND & METHODS: Youth of color are surveilled and arrested by police at higher rates than their White peers, contributing to racial inequities across the life course and in population health. Previous research points to schools as an increasingly relevant site for youth criminalization, but existing studies emphasize within-school mechanisms, with limited analysis of policing in surrounding school areas. To fill this gap, we study changes in police arrests of youth after initial COVID-19 school closures in 2020 across four US cities overall and in relation to public school locations. We analyze geocoded arrest records and use interrupted time series negative binomial regression models with city and month fixed effects to estimate change in weekly arrest rates among White, Black, and Latinx youth. We estimate arrest densities within school areas before and after school closures using spatial buffers of 300 feet. RESULTS: In the immediate weeks and months following COVID-19 pandemic school closures, youth arrest rates fell dramatically and with lasting impacts compared to other age groups. During the period of remote learning, weekly youth arrest rates declined by 54.0% compared to youth arrests rates in 2019, adjusting for city and seasonality (Incident Rate Ratio 0.46, 95% CI: 0.41, 0.52). We estimate Black youth weekly arrests fell from 43.6 to 16.8 per 100,000, vs. 4.6 to 2.2 per 100,000 among White youth. However, Black youth arrest rates during the remote learning period were still nearly 5 times that of White youth pre-pandemic. We also find that youth arrest rates declined during two school closure periods: at the start of the pandemic in 2020 and during Summer 2019. A spatial analysis shows Black and Latinx youth arrest densities in the surrounding 300 feet of K-12 schools were at least 15 and 8.5 times that of White youth, respectively, in both pre- and remote-learning periods. CONCLUSIONS: Black and Latinx youth face a higher likelihood of being arrested near a school than do White youth and older age groups, and racial inequities in arrests remains after school closures. Our findings show school closures significantly reduced arrests of urban youth of color, and policies addressing youth criminalization and structural racism should consider the joint spatial context of schools and policing. Although school closures may have resulted in learning loss and harms to youth wellbeing, closures interrupted comparatively high levels of arrest for Black and Latinx youth.

Vicarious severe school discipline predicts racial disparities among non-disciplined Black and White American adolescents.

Racial disparities in school discipline may have collateral consequences on the larger non-suspended student population. The present study leveraged two longitudinal datasets with 1201 non-suspended adolescents (48% Black, 52% White; 55% females, 45% males; Mage : 12-13) enrolled in 84 classrooms in an urban mid-Atlantic city of the United States during the 2016-2017 and 2017-2018 academic years. Classmates' minor infraction suspensions predicted greater next year's defiant infractions among non-suspended Black adolescents, and this longitudinal relation was worse for Black youth enrolled in predominantly Black classrooms. For White youth, classmates' minor infraction suspensions predicted greater defiant infractions specifically when they were enrolled in predominantly non-White classrooms. Racial inequities in school discipline may have repercussions that disadvantage all adolescents regardless of race.

Child protective services involvement and exclusionary school discipline.

The study examined the impact of child protective services (CPS) contact on out-of-school suspensions for 49,918 Wisconsin students (followed from ages 5-6 to 14-15; [school years 2010-2019; 74% White; 7% Black; 11% Hispanic; 8% other; 49% female]). A quasi-experimental design comparing recent CPS contact to upcoming (future) CPS contact shows that both recent CPS contact without foster care and future CPS contact predict higher odds of suspension compared with no contact. Higher odds of suspension emerged prior to CPS contact and did not substantially increase during or after CPS contact, suggesting that system-induced stress is not a primary driver of behavioral problems leading to suspension. Foster care reduced the odds of suspension among White children and children in special education.

School connectedness and psychological resilience as mediators in the relationship between childhood abuse and suicidal ideation among Chinese adolescents.

Background: Suicide among adolescents is a huge public health concern around the world. Although childhood abuse has been established as a substantial risk factor for suicide behaviours, potential mediators in this relationship remain unclear.Objective: This study aimed to examine the mediating roles of school connectedness and psychological resilience in the association between childhood abuse and suicidal ideation among Chinese high school students.Methods: The sample involved 1607 adolescents from four high schools in Central China. Structural equation modelling (SEM) was conducted to investigate the mediation effects of school connectedness and psychological resilience on the relationship between childhood abuse and suicidal ideation.Results: The prevalence of suicidal ideation during the past week was 21.9%. Childhood abuse was positively related to the development of suicidal ideation directly and indirectly through school connectedness and psychological resilience. School connectedness and psychological resilience were also partial mediators of all three types of childhood abuse (emotional abuse, physical abuse and sexual abuse) when the types were examined separately.Conclusions: Suicidal ideation was widespread among Chinese high school students. Psychological resilience and school connectedness could attenuate the detrimental impact of childhood abuse on suicidal ideation. Findings underscore the improvement of psychological resilience and the connection to the school would be beneficial to suicide prevention among Chinese adolescents with childhood abuse.

Adolescent suicide is a major public health concern worldwide.Childhood abuse exerts a negative effect on suicide behaviours.School connectedness and psychological resilience mediated the relationship between childhood abuse and suicidal ideation.

Health literacy and risk of viral hepatitis among Chinese school children.

INTRODUCTION: Poor literacy is associated with hepatitis morbidity and mortality. Adolescents are especially at risk of hepatitis C. This study investigated viral hepatitis literacy, risk, and influencing factors among Chinese middle and high school students. METHODOLOGY: A supervised self-administered survey was conducted with school children from six schools in Shantou, China. Data on demographics, health literacy, and risk of viral hepatitis were analyzed. RESULTS: A total of 1732 students (from three middle and three high schools) participated in the study. Their major information resources were the internet (39.5%, 685/1732), television (28.8%, 498/1732), family (27.7%, 479/1732), and school (21.2%, 368/1732). The mean literacy score on the manifestations and risk factors of hepatitis was 3.4 ± 2.2 and 4.0 ± 2.3 (out of 8), respectively. Multiple linear regression models showed being female and in high school, having parents with higher education levels, and school or clinicians as an information resource were independent positive predictors, whereas poor awareness of risk factors was a negative predictor for health literacy. CONCLUSIONS: We report the risk of hepatitis among Chinese middle and high school students due to limited literacy and poor attitudes towards health-risk behaviors. Health education in school is recommended for preventable health risks among Chinese adolescents.

Diagnostico "cuan saludable es mi escuela" escuelas saludables y entornos saludables / I diagnose "how healthy is my school" healthy schools and healthy environments

La Estrategia Escuela Saludable surge de una alianza entre los Ministerios de Educación y Salud, en el marco del convenio 100 de 1993 y 115 de 1994, como una de las principales estrategias de promoción de la salud. Esta estrategia es apoyada por la Organización Mundial de la Salud -OMS-, la Organización Panamericana de la Salud -OPS-, la Organización de Naciones Unidas para la Agricultura y la Alimentación ­FAO- y el Fondo de Población UNFPA. Dicha estrategia busca la promoción de la salud y la nutrición en el componente escolar, y fomenta o promueve la creación de entornos saludables, con la participación social a través de la comunidad educativa, y autoridades locales. Se define "Escuela Saludable" al centro educativo en el cual los alumnos y alumnas logran un armonioso desarrollo biológico, emocional y social en un ambiente de bienestar institucional y comunal, desarrollando estilos de vida saludables, todo lo cual es compartido con sus familias, maestros, personal de la escuela y la comunidad. Uno de los objetivos de las "Escuela Saludable" es contribuir a que en el establecimiento educativo los estudiantes desarrollen conocimientos, actitudes y prácticas de promoción de la salud, alimentación y nutrición, fomentando al mismo tiempo del cuidado de su propia salud, la relación con el entorno. En Guatemala la prevalencia de desnutrición crónica en menores de cinco años es la mayor de Latinoamérica y cuarta a nivel mundial1 . Las cifras del III Censo Nacional de Talla en Escolares del Primer Grado de Educación Primaria del Sector Oficial de la República2 , muestran que un 45.6% de este grupo de población, sufre de retardo de crecimiento o desnutrición crónica, la cual el área rural es mayor (49.7%). En el Departamento de Totonicapán, la prevalencia es de 69.4%, muy por encima del promedio nacional y en el área rural del departamento, es aún mayor (71%). La situación nutricional de Totonicapán contribuyó a que se seleccionara como área prioritaria de intervención del Programa Conjunto. La prevalencia de retardo en talla o desnutrición crónica según el idioma materno, muestra que es menor (34.6%) en los niños y niñas cuyo idioma materno es el español, mientras que los niños y niñas cuyo idioma materno no es el español, la prevalencia es mayor (62.5%), casi el doble.

Seasonal transmission dynamics of varicella in Japan: The role of temperature and school holidays.

In Japan, major and minor bimodal seasonal patterns of varicella have been observed. To investigate the underlying mechanisms of seasonality, we evaluated the effects of the school term and temperature on the incidence of varicella in Japan. We analyzed epidemiological, demographic and climate datasets of seven prefectures in Japan. We fitted a generalized linear model to the number of varicella notifications from 2000 to 2009 and quantified the transmission rates as well as the force of infection, by prefecture. To evaluate the effect of annual variation in temperature on the rate of transmission, we assumed a threshold temperature value. In northern Japan, which has large annual temperature variations, a bimodal pattern in the epidemic curve was observed, reflecting the large deviation in average weekly temperature from the threshold value. This bimodal pattern was diminished with southward prefectures, gradually shifting to a unimodal pattern in the epidemic curve, with little temperature deviation from the threshold. The transmission rate and force of infection, considering the school term and temperature deviation from the threshold, exhibited similar seasonal patterns, with a bimodal pattern in the north and a unimodal pattern in the south. Our findings suggest the existence of preferable temperatures for varicella transmission and an interactive effect of the school term and temperature. Investigating the potential impact of temperature elevation that could reshape the epidemic pattern of varicella to become unimodal, even in the northern part of Japan, is required.

The nature-nurture of academic achievement at the intersection between gender, family background, and school context.

We investigate the role of gender, family SES, school SES, and their intersection in educational achievement using a twin design. Drawing on theories of gene-environment interaction, we test whether high-SES environments compensate genetic risks or enhance genetic potential, and its dependency on gender. Using data on 37,000 Danish twin and sibling pairs from population-wide administrative registers, we report three main findings. First, for family SES, but not for school SES, we find that genetic influences play a slightly smaller role in high-SES environments. Second, this relationship is moderated by child gender: in high-SES families, the genetic influence is considerably lower for boys than for girls. Third, the moderating effect of family SES for boys is almost entirely driven by children attending low-SES schools. Our findings thus point to significant heterogeneity in gene-environment interactions, highlighting the importance of considering the multiplicity of social contexts.

Lifting Universal Masking in Schools - Covid-19 Incidence among Students and Staff.

BACKGROUND: In February 2022, Massachusetts rescinded a statewide universal masking policy in public schools, and many Massachusetts school districts lifted masking requirements during the subsequent weeks. In the greater Boston area, only two school districts - the Boston and neighboring Chelsea districts - sustained masking requirements through June 2022. The staggered lifting of masking requirements provided an opportunity to examine the effect of universal masking policies on the incidence of coronavirus disease 2019 (Covid-19) in schools. METHODS: We used a difference-in-differences analysis for staggered policy implementation to compare the incidence of Covid-19 among students and staff in school districts in the greater Boston area that lifted masking requirements with the incidence in districts that sustained masking requirements during the 2021-2022 school year. Characteristics of the school districts were also compared. RESULTS: Before the statewide masking policy was rescinded, trends in the incidence of Covid-19 were similar across school districts. During the 15 weeks after the statewide masking policy was rescinded, the lifting of masking requirements was associated with an additional 44.9 cases per 1000 students and staff (95% confidence interval, 32.6 to 57.1), which corresponded to an estimated 11,901 cases and to 29.4% of the cases in all districts during that time. Districts that chose to sustain masking requirements longer tended to have school buildings that were older and in worse condition and to have more students per classroom than districts that chose to lift masking requirements earlier. In addition, these districts had higher percentages of low-income students, students with disabilities, and students who were English-language learners, as well as higher percentages of Black and Latinx students and staff. Our results support universal masking as an important strategy for reducing Covid-19 incidence in schools and loss of in-person school days. As such, we believe that universal masking may be especially useful for mitigating effects of structural racism in schools, including potential deepening of educational inequities. CONCLUSIONS: Among school districts in the greater Boston area, the lifting of masking requirements was associated with an additional 44.9 Covid-19 cases per 1000 students and staff during the 15 weeks after the statewide masking policy was rescinded.

Conclusion: despite its originality, the experience of the pandemic found similarities in previous experiences of stressful events that allowed participants to learn and develop their resilience.

Interactional quality in middle schools: Latent profiles and their associations with teacher, classroom, and school compositional factors.

High quality teacher-student interactions are critical for the healthy social-emotional, behavioral, and academic development of middle school students. However, few studies have explored patterns of teacher-student interactions in middle school classrooms or the relation between teacher-, classroom-, and school-level factors and patterns of interaction. The current study employed latent profile analyses (LPA) to identify patterns of teacher-student interactional quality in a sample of 334 teachers from 41 schools serving middle school students within the Mid-Atlantic region of the U.S. Three distinct profiles of teacher-student interactional quality were identified that were characteristic of higher, lower, and intermediate quality and were differentially related to teacher, classroom, and school characteristics. Compared to classrooms with lower interactional quality, classrooms with "higher" or "intermediate" profiles were more likely to be taught by early career teachers, to have higher rates of observed student cooperation, and to be in schools in rural fringe areas. Classrooms with lower interactional quality were more likely to have larger student-to-teacher ratios and higher rates of student disruptive behaviors than classrooms with intermediate interactional quality and to be in schools with a higher percentage of out-of-school suspensions than classrooms with higher interactional quality. These findings suggest that interventions at the teacher, classroom, and school levels may promote positive teacher-student interactions, such as consultation to support teachers' effective classroom management, alternatives to out-of-school suspensions, and smaller student-to-teacher ratios.

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 .

Tecnoadicción y uso compulsivo de internet en estudiantes universitarios / Technology addiction and compulsive internet use in university

Introducción: uno de los efectos nocivos de las tecnologías de la información y la comunicación (TIC) es su uso sin control, lo que ha generado una adicción hacia ellas. Objetivo: conocer la prevalencia de tecnoadicción de las TIC en estudiantes universitarios de nivel superior, posgrado y profesionistas de diferentes áreas. Metodología: estudio descriptivo cuya población fueron universitarios de nivel superior, posgrado y profesionistas de diferentes áreas de la Universidad Nacional Autónoma de México (UNAM) y del Instituto Politécnico Nacional (IPN) durante el ciclo escolar 2020-2. El muestreo fue no probabilístico. Resultados: al analizar los datos de la Escala de adicción de internet, el 49% respondió que permanece en internet más tiempo del que desea y el 38.2% mencionó que intenta reducir la cantidad de tiempo que pasa en línea. En cuanto al uso compulsivo, el 32.8% mencionó que sigue usando internet a pesar de que su intención es reducir su uso; el 30.5% dice que está corto de sueño debido al uso de internet. Conclusiones: existe tecnoadicción entre profesionistas y estudiantes universitarios de nivel superior y posgrado de la UNAM y del IPN. El personal de salud debe establecer estrategias de prevención del uso del internet para evitar trastornos de salud mental como depresión y aislamiento, entre otros.

Background: One of the harmful effects of the information and communication technologies (ICTs) is their uncontrolled use, which has generated an addiction to them. Objective: To know the prevalence of technology addiction of ICTs in university students of higher level, postgraduate and professionals from different areas. Methodology: Descriptive study whose population was university students of higher level, postgraduate degrees and professionals from different areas of the National Autonomous University of Mexico (UNAM) and the National Polytechnic Institute (IPN) during the 2020-2 school year. The sampling was non-probabilistic. Results: When analyzing the data of the Internet addiction scale, 49% responded that they stay on the internet much more time than what they want to, and 38.2% mentioned that they try to reduce the amount of time they spend online. As for compulsive use, 32.8% mentioned that they continue to use the internet despite the fact that their intention is to use it less; 30.5% say they are short of sleep due to internet use. Conclusions: There is technology addiction among professionals and university students of higher and postgraduate levels of UNAM and IPN. Health personnel must establish prevention strategies for the use of internet, in orded to avoid mental health disorders such as depression, isolation, among others.

Use of Acute Mental Health Care in U.S. Children's Hospitals Before and After Statewide COVID-19 School Closure Orders.

Objective: This study aimed to examine changes in child emergency department (ED) discharges and hospitalizations for primary general medical (GM) and primary psychiatric disorders; prevalence of psychiatric disorders among acute care encounters; and change in acute mental health (MH) care encounters by disorder type and, within these categories, by child sociodemographic characteristics before and after statewide COVID-19­related school closure orders. Methods: This retrospective, cross-sectional cohort study used the Pediatric Health Information System database to assess percent changes in ED discharges and hospitalizations (N=2,658,474 total encounters) among children ages 3­17 years in 44 U.S. children's hospitals in 2020 compared with 2019, by using matched data for 36- and 12-calendar-week intervals. Results: Decline in MH ED discharges accounted for about half of the decline in ED discharges and hospitalizations for primary GM disorders (−24.8% vs. −49.1%), and MH hospitalizations declined 3.4 times less (−8.0% vs. −26.8%) in 2020. Suicide attempt or self-injury and depressive disorders accounted for >50% of acute MH care encounters before and after the statewide school closures. The increase in both ED discharges and hospitalizations for suicide attempt or self-injury was 5.1 percentage points (p<0.001). By fall 2020, MH hospitalizations for suicide attempt or self-injury rose by 41.7%, with a 43.8% and 49.2% rise among adolescents and girls, respectively. Conclusions: Suicide or self-injury and depressive disorders drove acute MH care encounters in 44 U.S. children's hospitals after COVID-19­related school closures. Research is needed to identify continuing risk indicators (e.g., sociodemographic characteristics, psychiatric disorder types, and social determinants of health) of acute child MH care.

Tracking of physical activity and sedentary behavior of adolescents in different domains

This study aimed to verify the tracking of physical activity and sedentary behavior in different domains during adolescence. This longitudinal study involved 265 subjects (boys: 52.8%) with an initial mean age of 13.9 (± 1.2) years. Physical activity and sedentary behavior were verified using a questionnaire. The achievement of ≥ 150 min. week-1of moderate-to-vigorous intensity sport and/or physical exercise for ≥ 1 month was adoptedas sufficiently active. The data were collected on 2 occasions, with an average interval of 3 years. The description of the results used the relative frequency and Binary Logistic Regression was used to estimate the crude and adjusted odds ratios (95% confidence intervals). Current physical activity (adjusted odds ratios = 3.05; 95% confidence intervals: 1.77 -5.26) and sedentary behavior (adjusted odds ratios = 1.81; 95% confidence intervals: 1.03 -3.19) appear to be significantly influenced by previousbehavior, except for light-intensity physical activity. Only 12.8% of the participants remained sufficiently active for sport and/or physical exercise. Practice for at least one month of sport and/or physical exercise at baseline was a predictor of practice in the follow-up, both considering participation for at least one month (adjusted odds ratios = 2.81; 95% confidence intervals: 1.37 -5.79) and for four months (adjusted odds ratios = 2.47; 95% confidence intervals: 1.17 -5.24) in the follow-up. Beingsufficiently active at baseline increased the chance of being sufficiently active in the follow-up during adolescence. Interventions providing sufficient sport and/or physical exercise could positively influence the chances of practice in the future. For light-intensity physical activity interventions, strategies targeting adherence seem especially relevant.
