RESUMO

Introduction: teachers have to adapt during the coronavirus disease 2019 (COVID-19) pandemic to many changes that could potentially make them more vulnerable to psychological distress. We aimed to assess anxiety and depression in Tunisian secondary school teachers during the COVID-19 pandemic and to explore their associated factors. Methods: we conducted a cross-sectional survey concerning Tunisian secondary school teachers between May 1st, 2021, and June 30th, 2021, using an online survey platform via Google Forms. Participants were asked to fill in a form including two psychometric tests: the General Anxiety Disorder 7 (GAD-7) and the Patient Health Questionnaire 9 (PHQ-9). We performed both univariable and multivariable logistic regression analyses. Results: a total of 170 secondary school teachers were included, of whom 22.4% (n=38) were males and 77.6% (n=132) were females. The median age was 45.5 years (Q1=39, Q3=49). The overall anxiety prevalence was 34.7% (n=59) while it was 41.7% (n=71) for depression. In multivariable analysis, anxiety was strongly associated with sleep disturbances (aOR: 5.1; 95% CI: 1.80-14.45; p=0.002) and depression (aOR: 33.91; 95% CI: 12.32-93.33; p<0.001) while depression was strongly associated with dissatisfaction with working conditions (aOR: 3.99; 95% CI: 1.49-10.65; p=0.006), the irregular wearing of protective masks (aOR: 3.94; 95% CI: 1.33-11.66; p=0.013) and anxiety (aOR=51.63; 95% CI: 17.74-150.25; p<0.001). Conclusion: secondary school teachers in Tunisia are characterized by a high rate of anxiety and depressive disorders which are related to personal and professional factors on which we can act by supplying of educational institutions by protective masks, the implementation of programs for adjusting working conditions and the practice of non-pharmacological interventions for insomnia management.

RESUMO

Background: This study investigated the level of anxiety and depression in Chinese college students since the COVID-19 pandemic and explored the sources of their negative emotions and students' self-emotion regulation strategies. Methods: A stratified cluster sampling questionnaire was used to survey college students during the pandemic via the Anxiety Depression, Self-made Negative Emotion Source, and Negative Emotion Regulation Strategy Scales. Results: The prevalence of anxiety and depression was 23.3 and 20.1%, respectively. These levels were higher in women than in men. Furthermore, senior students reported higher levels than freshmen. Anxiety and depression mainly came from the pressure to grow and the narrowed scope of social activities. Proper relaxation via entertainment and communication with family and friends were popular ways of regulating their negative emotions. Conclusion: College students should confront their negative emotions and understand their source, use psychological methods to regulate their anxiety and depression or seek professional help, improve their psychological resilience, and adopt positive coping measures.

RESUMO

INTRODUCTION: Long-term availability of health-promoting interventions (HPIs) in school settings can translate into health benefits for children. However, little is known about factors associated with HPI institutionalization in schools. In this study, we identified correlates of the institutionalization of HPIs offered in elementary schools in Quebec, Canada. METHODS: In two-part, structured telephone interviews over three academic years (2016-2019), elementary school principals (or their designees) throughout Quebec identified an index HPI offered at least once in their school during the previous three years, and were asked whether it was institutionalized (i.e. explicitly written in the school's educational project, e.g. in the form of educational objectives and means of achieving them). We examined associations between institutionalization and 10 school-related and 16 HPI-related characteristics in univariable and multivariable logistic regression analyses. RESULTS: School key informants (n = 163) reported on 147 different HPIs that had been available in their schools in the past three years, 56% of which were institutionalized. Three aspects of school culture-parent/community engagement with the school, school/teacher commitment to student health and school physical environment-were positively associated with HPI institutionalization. HPI-related characteristics positively associated with HPI institutionalization included number of competencies addressed by the HPI, number of teaching strategies employed, modifications made to the HPI prior to or during implementation and perceived success of the HPI. Inviting families or community groups to participate in the HPI was inversely associated with institutionalization. CONCLUSION: Better understanding of factors associated with HPI institutionalization may inform the development of school-based HPIs that have the potential for sustainability.

RESUMO

The early prevention of non-communicable diseases in Cameroon schools program was initiated in 2018 to address the alarming trend of obesity among adolescents through a nutrition education intervention aimed at increasing knowledge on nutrition and the benefits of healthy eating and physical activity. The program included: school surveys to document eating habits and health-risky behaviors in students, the development of a training curriculum, training and sensitization sessions for school staff, school vendors and students, and advocacy meetings with parliamentarians and mayors. We carried out a quasi-experimental study to assess the effect of the intervention on the student's knowledge and eating behavior three months after the training sessions. We compared the knowledge of a sample of students from five schools that were part of the program (IG) to that of students that were not (CG). The mean (±SD) score was 14.4/20 (±2.1) and 9.7/20 (±2.7) for IG and CG, respectively (p<0.001). Those who scored above 12/20 accounted for 89.8% of IG vs 23.8% of CG (p<0.001). Other significant achievements of this program are the amendment of the National School Hygiene Policy to include compulsory training in food hygiene and nutrition education for school canteen vendors and the integration of nutrition education sensitization sessions into the routine activities of school healthcare. The study showed that a well-structured multi-sectoral nutritional education program could be the bedrock to improve healthy nutrition among adolescents, thereby serving as a vehicle for non-communicable disease prevention.

RESUMO

BACKGROUND: In Sierra Leone, adolescents are increasingly engaging in risky activities, including cannabis use, which can lead to substance abuse, poor academic performance, and psychotic symptoms. This study aims to investigate the prevalence and associated factors of cannabis use among school-going adolescents in the country. METHOD: Data for the study was sourced from the 2017 Sierra Leone Global School-based Student Health Survey (GSHS), a nationally representative survey conducted among adolescents aged 10-19 years using a multistage sampling methodology. A weighted sample of 1,467 adolescents in Sierra Leone was included in the study. The study utilised bivariate and multivariable logistic regression analysis to identify factors linked to cannabis use, presenting results using adjusted odds ratios and 95% confidence intervals. RESULTS: The prevalence of cannabis use was 5.1% [3.0,8.6] among school-going adolescents in Sierra Leone. School-going adolescents who attempted suicide [aOR = 6.34, 95% CI = 1.71-23.45], used amphetamine [aOR = 15.84, 95% CI = 7.94-31.62] and were involved in sexual risk behaviour [aOR = 5.56, 95% CI = 2.18-14.20] were more likely to be associated with cannabis use. CONCLUSION: In Sierra Leone, a small but non-trivial minority of students use cannabis. Ever-used amphetamines or methamphetamines, suicidal attempts, and sexual risk behaviour were the factors associated with cannabis use in Sierra Leone. The development of school-based health intervention programmes is crucial to address the risk factors associated with cannabis use among school-going adolescents.

RESUMO

BACKGROUND: Children's educational experiences worldwide have been significantly impacted as a result of global school closures during the COVID-19 pandemic of Spring 2020. A growing number of studies aim to analyse impacts of these changes on social well-being, with limited studies placing an emphasis on the experiences of students with special educational needs (SENs). This article focusses on parent perspectives regarding impacts of school closures on social well-being in Canadian children with SEN. METHODS: This study uses a mixed-methods approach, drawing from both qualitative and quantitative survey data from Spring/Summer 2020. Participants (n = 263) were eligible for participation if they were a parent/guardian of a child or adolescent with an SEN. We first conducted a descriptive analysis of the key variables, namely, social well-being, grade level of the child, internet and device availability, and the presence of other school-aged children in the home (single child vs. multiple children). Next, we explored the relationship between these using a bivariate correlation. Finally, open-ended responses were analysed using an inductive approach to qualitative thematic analysis. RESULTS: The majority of parents expressed concern for their child's social well-being during the Spring 2020 school closures, with increased concerns for younger children. According to parents, children experienced communication barriers to peer interaction and many experienced emotional difficulties as a result. Technology was described as critical for some in maintaining social connections. Parents raised concerns about the impact of limited peer interaction on broader social skill development, in the short and long term. A small number of participants noted feelings of relief and reduced anxiety among their children with SEN. CONCLUSIONS: Findings highlight parent views of the negative impact of the pandemic on social well-being and the critical role in-person schooling plays in supporting peer relationships for children with SEN.

RESUMO

Introduction: An important impediment to the large-scale adoption of evidence-based school nutrition interventions is the lack of evidence on effective strategies to implement them. This paper describes the protocol for a "Collaborative Network Trial" to support the simultaneous testing of different strategies undertaken by New South Wales Local Health Districts to facilitate the adoption of an effective school-based healthy lunchbox program ('SWAP IT'). The primary objective of this study is to assess the effectiveness of different implementation strategies to increase school adoption of the SWAP across New South Wales Local Health Districts. Methods: Within a Master Protocol framework, a collaborative network trial will be undertaken. Independent randomized controlled trials to test implementation strategies to increase school adoption of SWAP IT within primary schools in 10 different New South Wales Local Health Districts will occur. Schools will be randomly allocated to either the intervention or control condition. Schools allocated to the intervention group will receive a combination of implementation strategies. Across the 10 participating Local Health Districts, six broad strategies were developed and combinations of these strategies will be executed over a 6 month period. In six districts an active comparison group (containing one or more implementation strategies) was selected. The primary outcome of the trial will be adoption of SWAP IT, assessed via electronic registration records captured automatically following online school registration to the program. The primary outcome will be assessed using logistic regression analyses for each trial. Individual participant data component network meta-analysis, under a Bayesian framework, will be used to explore strategy-covariate interactions; to model additive main effects (separate effects for each component of an implementation strategy); two way interactions (synergistic/antagonistic effects of components), and full interactions. Discussion: The study will provide rigorous evidence of the effects of a variety of implementation strategies, employed in different contexts, on the adoption of a school-based healthy lunchbox program at scale. Importantly, it will also provide evidence as to whether health service-centered, collaborative research models can rapidly generate new knowledge and yield health service improvements. Clinical trial registration: This trial is registered prospectively with the Australian New Zealand Clinical Trials Registry (ACTRN12623000558628).

RESUMO

This study was designed to explore mothers' perceptions about changes in parenting behavior in the middle of the pandemic COVID 19 period. Based on the convergent mixed-method design and Parental Stress model, we illustrated these changes by taking into account the impact of the pandemic perceived by mothers and the resources they had available. Research on parenting changes was important in the Romanian context because, in that challenging period, there were no regulations to safeguard parents, especially single parents as mothers. Mothers experienced increased levels of stress, some of them having to leave their jobs to stay at home with their children. Other mothers needed to work from home and in the meantime to take care of their children. In this context we wanted to illustrate the possible changes that occurred in their parenting behavior during the pandemic period. Results from the quantitative survey showed that there is a moderate correlation between the negative impact felt by mothers and the negative changes in their parenting behavior, and this correlation was diminished by a series of resources such as: social support, parenting alliance, or high income. Qualitative data provided better understanding of mothers' parenting behavior by showing that mothers shared both positive and negative experiences during the pandemic, regardless of the general trend mentioned. As shown by the quantitative data, the qualitative data also showed that mothers who felt more strongly the impact of the pandemic reported more negative changes in their parenting behavior. The positive changes most frequently stated involved expressing affection and communicating more often on various topics, carrying out leisure activities or activities meant to help with the personal development of the child, and involving children in domestic activities. Mothers mostly described negative aspects such as too much involvement in school life, increased control and surveillance of children, especially when it comes to school related activities and to the time children were allowed to spend on their digital devices. These changes led to conflicts and sometimes, mothers resorted to discipline practices. In addition to the resources identified in quantitative research, mothers with higher education and medium-high income also turned to specialized resources (psychologists, online courses, support groups) in order to manage conflicts, them being able to see the challenges of the pandemic as an opportunity to develop and improve the relationship with their children.

RESUMO

The pharmaceutical literacy is a necessary element of ensuring quality of human life that is to be formed at early age. The article demonstrates that key direction of development of health literacy is pharmaceutical education involving pharmaceutical workers. The necessity of development of pharmaceutical literacy in children through involvement into process of pharmaceutical education pedagogues and parents/legal representatives of child. The article presents analysis of normative legal documents regulating strategic directions of state and international policy in the field of protection of health and rights of minor citizen/children that regulate organization of pharmaceutical and educational activities and requirements to pharmaceutical and pedagogical workers within the framework of their professional role. The problematic zones in organization of pharmaceutical counseling of minors citizen were discovered. The necessity to improve professional competence of pharmaceutical and pedagogical workers in organization of pharmaceutical education of children of preschool and school age is established. The results of sociological survey of minor citizen and their parents demonstrated inadequate level of pharmaceutical literacy of respondents. On the basis of research results structural model of interaction of participants of pharmaceutical education of children (pharmaceutical workers - parents - pedagogues). The communication relations at the stage of transferring pharmaceutical knowledge to minor personality were revealed. The main result of the study is original structural functional model of organization of pharmaceutical education of children implementing interdisciplinary approach in forming pharmaceutical knowledge in children of preschool and school age. The stages of interaction of participants and professional tasks of pharmaceutical and pedagogical specialists in process of teaching children skills of pharmaceutical safety are determined.

RESUMO

BACKGROUND: For students to feel happy and supported in school, it is important that their views are taken seriously and integrated into school policies. However, limited information is available how the voices of immigrant students are considered in European school contexts. This study generated evidence from written documents to ascertain how student voice practices are described at school websites. METHODS: Between 2 March and 8 April 2021, we reviewed the policy documents publicly available on school websites. The schools located in areas of high immigration in six European countries: Austria, England, Finland, Germany, Romania, and Switzerland. The READ approach was used to guide the steps in the document analysis in the context of policy studies (1) ready the materials, 2) data extraction, 3) data analysis, 4) distil the findings). A combination of qualitative and quantitative approaches with descriptive statistics (n, %, Mean, SD, range) was used for analysis. RESULTS: A total of 412 documents (305 schools) were extracted. Based on reviewing school websites, reviewers'strongly agreed' in seven documents (2%) that information related to seeking student voices could be easily found. On the contrary, in 247 documents (60%), reviewers strongly indicated that information related to seeking student voices was missing. No clear characteristics could be specified to identify those schools were hearing students' voices is well documented. The most common documents including statements related to student voice were anti-bullying or violence prevention strategies (75/412) and mission statements (72/412). CONCLUSIONS: Our document analysis based on publicly accessible school websites suggest that student voices are less frequently described in school written policy documents. Our findings provide a baseline to further monitor activities, not only at school level but also to any governmental and local authorities whose intention is to serve the public and openly share their values and practices with community members. A deeper understanding is further needed about how listening to student voices is realized in daily school practices.

RESUMO

BACKGROUND: Physical activity (PA) promotes health in adults as well as children. At the same time, a large proportion of children do not meet the recommendations for PA, and more school-based efforts to increase PA are needed. This study investigates the effectiveness and feasibility of lesson-integrated PA in a Swedish primary school. METHODS: We evaluate a new method called 'Physical Activity and Lesson in Combination' (abbreviated FALK in Swedish) using a mixed methods approach; a quasi-experimental study followed by qualitative interviews. Two schools participated in the study, one constituting the intervention group (I-school, n = 83) and the other the control group (C-school, n = 81). In addition to regular physical education, the I-school had three 30-minute FALK lessons each week. A total of 164 students aged 7-9 years wore pedometers for a whole week, four times over two semesters, and the number of steps per day (SPD) and the proportion of students with < 10,000 SPD were compared. Statistical differences between the schools were tested with ANOVA, Chi2, t-tests, and ANCOVA. Interviews with students (n = 17), parents (n = 9) and teachers (n = 9) were conducted and analysed using qualitative content analysis. RESULTS: The results show that FALK led to the I-school getting more SPD and fewer students with < 10,000 SPD. Also, FALK was experienced as a positive, clear, and flexible method, simultaneously encouraging PA and learning. Challenges experienced concerned the teachers' work situation, time, finding suitable learning activities, outdoor school environment changes, and extreme weather conditions. CONCLUSIONS: This study indicates that FALK has the desired effects on PA and is a feasible method of integrating PA into theoretical teaching. We conclude that FALK is worth testing at more schools, given that implementation and sustainment of FALK considers both general enablers and barriers, as well as context-specific factors at the individual school.

RESUMO

BACKGROUND: Past research describes robust associations between education and health, yet findings have generally been limited to the examination of education as the number of years of education or educational attainment. Little is known about the specific features or processes underpinning education that are health protective. The objective of the current study was to address this gap by examining specific aspects of early education pertaining to student characteristics and experiences, as well as features of the classroom environment, in predicting cardiometabolic health in adulthood. METHODS: Subjects were 1364 participants in the NICHD Study of Early Child Care and Youth Development (SECCYD, 1991-2009) and recent SECCYD 30-year follow-up, the Study of Health in Early and Adult Life (SHINE, 2018-2022). Models examined individual education indicators (student social skills, student-teacher relationship quality, and classroom emotional and instructional quality in the period of elementary school and student academic performance between ages 54 months and 15 years) in relation to a composite of cardiometabolic risk in adulthood (ages 26-31), reflecting central adiposity, blood pressure, insulin resistance, inflammation, and dyslipidemia. Models were adjusted for key explanatory factors including socio-demographics, infant characteristics, parental socioeconomic status (SES), and child health status. Follow-up analyses were performed to test potential mediators of early education effects on adult health, including adult SES (educational attainment, household income) and health behaviors (diet quality, activity level, sleep duration, smoking). RESULTS: In adjusted models, results showed greater student social skills, indexed by a mean of annual teacher ratings between kindergarten and 6th grade, predicted lower cardiometabolic risk in adulthood (ß=-0.009, p <.05). In follow-up analyses, results showed the protective effect of student social skills on cardiometabolic risk may be mediated by adult income (ß=-0.0014, p <.05) and diet quality (ß=-0.0031, p <.05). Effects of the other early education indicators were non-significant (ps > 0.05). CONCLUSIONS: Findings point to the potential significance of early student social competence as a link to long-term health, possibly via the acquisition of resources needed for the maintenance of health, as well as through engagement in health behaviors supporting healthy eating. However, more research is needed to replicate these findings and to elaborate on the role of early student social competence and the pathways explaining its effects on cardiometabolic health in adulthood.

RESUMO

The University of Puerto Rico School of Dentistry was established in 1957. Over the years, it has played an important role in Puerto Rico's healthcare system. That legacy is displayed through the walls of the School of Dentistry. In Part 1, the evolution of 20-year-old dental museum-like showcases located in the lobby and the main hallway of the school were described along with important professions who impacted on this development. In this paper, we will describe in detail the items available at the museum.

RESUMO

Computational models are used to examine the effect of schooling on flow generated noise from fish swimming using their caudal fins. We simulate the flow as well as the far-field hydrodynamic sound generated by the time-varying pressure loading on these carangiform swimmers. The effect of the number of swimmers in the school, the relative phase of fin flapping of the swimmers, and their spatial arrangement is examined. The simulations indicate that the phase of the fin flapping is a dominant factor in the total sound radiated into the far-field by a group of swimmers. For small schools, a suitable choice of relative phase between the swimmers can significantly reduce the overall intensity of the sound radiated to the far-field. The relative positioning of the swimmers is also shown to have an impact on the total radiated noise. For a larger school, even highly uncorrelated phases of fin movement between the swimmers in the school are very effective in significantly reducing the overall intensity of sound radiated into the far-field. The implications of these findings for fish ethology as well as the design and operation of bioinspired vehicles are discussed.

RESUMO

In this study, the waste generation at the educational institutes chosen from four different levels (kindergartens, primary, secondary and high schools) in Istanbul was measured on-site and the contents of the waste thrown into the recycling bins were determined to specify capture rates. Separation and weighing processes were performed at 16 spots in high schools, 12 spots in secondary schools, 7 spots in primary schools and 7 spots in kindergartens. A survey was conducted to determine the students' awareness of recycling in these schools. It was revealed that the wastes produced from educational institutes are organics (36.4 %), paper (24 %), plastics (14.4 %), glass (8.1 %), metals (4.8 %) and miscellaneous (12.3 %). The survey results indicate that 93 % of the participants think recycling is important, 71 % of them throw their waste into suitable waste bins and 59 % of them know the location of the recycling bins. At the primary school level, a very high rate of paper waste (92.3 %) was reported in plastic bins while plastic waste collected in these bins remained only 5.7 %. It was also seen that glass waste captured in glass bins and metal waste in metal bins remain very low rates (20.9 % and 29.2 %, respectively) at the secondary school level. At the high school level, it was determined that the most commonly captured wastes in glass, plastics and paper bins are glass (47.5 %), plastic (43.2 %) and paper (32.5 %), respectively. Correlation analyses indicated a high positive correlation (p < 0.05) between particular types of waste.
