RESUMO

Modifications to the social-ecological model, such as Whole School, Whole Community, Whole Child (WSCC) frameworks, have been utilized in comprehensive school health interventions. Classroom physical activity breaks are used when implementing whole-of-school approaches. However, the onus to implement classroom physical activity breaks is on school stakeholders. This study aimed to explore teacher and principal perceptions and implementation of physical activity breaks in elementary schools. Further, this study investigated how theoretical factors representative of the social-ecological model and their interactions affect teacher and principal perceptions and utilization of classroom physical activity breaks. Interviews were conducted to understand teacher and principal perceptions and implementation. A total of 12 classroom teachers and five principals participated in semi-structured interviews which were analyzed using constant comparison and deductive analysis to identify relationships and themes coded across the social-ecological and WSCC models. To ensure fidelity individuals that led the professional development (n = 2) were also interviewed. Three main themes emerged as part of the data analysis: (i) The Connection Between Intrapersonal Knowledge and Interpersonal Professional Development, (ii) Resources, Sharing Means Caring and (iii) The Policy Level Creates Time. Teachers and principals valued knowledge and resources and felt that policy facilitated implementation. Results suggest that classroom physical activity breaks are influenced by multiple factors across varied levels of the social-ecological model. Understanding this relationship can inform future professional development to increase the provision of classroom physical activity breaks among teachers.


Global health statistics suggest that youth health is deteriorating. In response, international and national health organizations have called for school settings to adopt comprehensive school health approaches that provide youth with ample opportunities, such as physical activity across the school day, to improve their health behaviors and instill lifelong healthy habits. This study used the social­ecological model, which considers the interactions between an individual, their community, and the physical, social and political environments, to frame the exploration of how teachers and principals perceive and utilize physical activity breaks in elementary schools. Findings indicate that to foster school health, a comprehensive approach that supports teachers and their interactions while providing resources and policies is needed. Adoption of classroom physical activity breaks begins with teacher knowledge which fosters teacher interaction where best practices are built. Structural supports, including access to resources and the presence of policy, are also critical to sustained implementation because they can reinforce and support teachers' individual and shared use of health-based learning practices across the school day.

RESUMO

The study of physical activity, physical fitness, and academic performance research are reviewed from a historical perspective, by providing an overview of existing publications focused on children and adolescents. Using rigorous inclusion criteria, the studies were quantified and qualified using both meta-analytic and descriptive evaluations analyses, first by time-period and then as an overall summary, particularly focusing on secular trends and future directions. This review is timely because the body of literature is growing exponentially, resulting in the emergence of new terminology, methodologies, and identification of mediating and moderating factors. Implications and recommendations for future research are summarized.

RESUMO

Background: Dysregulation of the endocannabinoid (eCB) system is implicated in various stress-related neuropsychiatric disorders (SRDs), including anxiety, depression, and post-traumatic stress disorder (PTSD). In this systematic review and meta-analysis, our objectives were to characterize circulating anandamide (AEA) and 2-arachidonoylglycerol (2-AG) concentrations at rest and in response to acute laboratory-based psychosocial stress in individuals with SRDs and without (controls). Our primary aims were to assess the effects of acute psychosocial stress on eCB concentrations in controls (Aim 1), compare baseline (prestress) eCB concentrations between individuals with SRDs and controls (Aim 2), and explore differential eCB responses to acute psychosocial stress in individuals with SRDs compared with controls (Aim 3). Methods: On June 8, 2023, a comprehensive review of the MEDLINE (PubMed) database was conducted to identify original articles meeting inclusion criteria. A total of 1072, 1341, and 400 articles were screened for inclusion in Aims 1, 2, and 3, respectively. Results: Aim 1, comprised of seven studies in controls, revealed that most studies reported stress-related increases in AEA (86%, with 43% reporting statistical significance) and 2-AG (83%, though none were statistically significant except for one study in saliva). However, meta-analyses did not support these patterns (p's>0.05). Aim 2, with 20 studies, revealed that most studies reported higher baseline concentrations of both AEA (63%, with 16% reporting statistical significance) and 2-AG (60%, with 10% reporting statistical significance) in individuals with SRDs compared with controls. Meta-analyses confirmed these findings (p's<0.05). Aim 3, which included three studies, had only one study that reported statistically different stress-related changes in 2-AG (but not AEA) between individuals with PTSD (decrease) and controls (increase), which was supported by the meta-analysis (p<0.001). Meta-analyses showed heterogeneity across studies and aims (I2=14-97%). Conclusion: Despite substantial heterogeneity in study characteristics, samples, and methodologies, consistent patterns emerged, including elevated baseline AEA and 2-AG in individuals with SRDs compared with controls, as well as smaller stress-related increases in 2-AG in individuals with SRDs compared with controls. To consider eCBs as reliable biomarkers and potential intervention targets for SRDs, standardized research approaches are needed to clarify the complex relationships between eCBs, SRDs, and psychosocial stress.

RESUMO

BACKGROUND: Given levels of sedentary behavior among youth, teachers have been called upon to increase physical activity (PA) by implementing classroom PA breaks. School-based interventions enacted in classroom settings have shown promise in increasing youth PA. Yet little is known about how teacher efficacy toward implementing classroom PA breaks may influence intervention effects. PURPOSE: Therefore, the purpose of this study was to examine how the Dearborn School Health through Integrated Nutrition and Exercise Strategies (D-SHINES) intervention, implemented across 8 schools, influenced classroom teacher's efficacy toward providing classroom PA breaks. METHODS: A mixed-methods design examined classroom teachers' efficacy toward implementing classroom PA breaks and used semi-structured interviews to better understand teachers' efficacy and implementation. RESULTS: Quantitative results indicated that teacher efficacy significantly increased over the intervention period and that general and institutional efficacy predicted higher amounts of PA breaks offered. Qualitative results suggested that to enhance teachers' facilitation of classroom PA breaks, one must tap into the institutional, student, and educational factors that constitute teacher efficacy. IMPLICATIONS FOR SCHOOL HEALTH: Designing interventions that focus on teacher efficacy toward classroom PA may be a viable way to increase PA breaks in schools. Implications for the whole school, whole community, whole child model are discussed.

RESUMO

Introduction: The social and emotional health of youth is important, especially after students experience the COVID-19 pandemic. The purpose of this study was to understand the influence that the Believe In You Student Empowerment Program had on students social emotional learning (SEL) behaviors over a 10 week period during the COVID-19 pandemic. Materials and methods: A part of this quantitative study, one school in each the intervention and the control group (delayed intervention; 2 schools total) participated in the study. Students enrolled in physical education within each school participated (n = 166; Intervention = 88). Students in each group took a survey at week 1 (baseline measure), week 5, and week 10. Students who were in the intervention group started the program after week 1, while the delayed intervention group began the program in week 5. Results: A series of ANCOVA's examined the difference of social emotional learning knowledge and social emotional learning scales between the treatment and control groups. Self-awareness (F = 13.91, p < .01), self-management (F = 6.14, p < .01) & relationship skills (F = 5.50, p < .05) saw significant differences over time compared to the control group. The second series of analyses looked only at the intervention group and analyzed to determine significant differences in mean scores of SEL variables between weeks one and ten. Emotional regulation saw significant differences (t = 2.5, p < .01). The final set of analyses conducted were with the delayed intervention group and examined the difference in mean SEL scores over the three time periods. Again, emotional regulation saw significance with an interaction of time and gender (F = 4.162, p < .01). Discussion and Conclusion: In a short period of time, Believe in You Student Empowerment Program has shown the potential to have a positive influence on students social emotional learning behaviors, even during the COVID-19 pandemic. More research should be conducted over a longer period of time, in-person, and with an experimental design to better understand the effects of the Varsity Brands Believe in You Student Empowerment Program and its implications with student social emotional learning behaviors.

RESUMO

INTRODUCTION: Grounded in organizational change theory, the purpose of this study was to investigate the efficacy of the Presidential Youth Fitness Program (PYFP) and its association with healthy cultures within schools. METHODS: Using a qualitative approach, data were collected through interviews, site visits and artifacts across 374 schools. An explanatory collective case study approach was used to identify key events related to implementation. RESULTS: Pivotal antecedents to organizational change included prolonged, continual PD, direct support of PYFP implementation, and recognition. Further, three key themes of leveling of the playing field, strategically overcoming barriers, and recruiting teacher fitness champions were identified. CONCLUSIONS: Creating a healthy school culture was an unexpected, but feasible outcome stemming from the implementation of the PYFP. A collective effort, led by physical education teachers and fitness champions and embraced by the administration, faculty, and community, is necessary for the school culture to unfreeze from its present status.

RESUMO

Child sleep disorders are increasingly prevalent and understanding early predictors of sleep problems, starting in utero, may meaningfully guide future prevention efforts. Here, we investigated whether prenatal exposure to maternal psychological stress is associated with increased sleep problems in toddlers. We also examined whether fetal brain connectivity has direct or indirect influence on this putative association. Pregnant women underwent fetal resting-state functional connectivity MRI and completed questionnaires on stress, worry, and negative affect. At 3-year follow-up, 64 mothers reported on child sleep problems, and in the subset that have reached 5-year follow-up, actigraphy data (N = 25) has also been obtained. We observe that higher maternal prenatal stress is associated with increased toddler sleep concerns, with actigraphy sleep metrics, and with decreased fetal cerebellar-insular connectivity. Specific mediating effects were not identified for the fetal brain regions examined. The search for underlying mechanisms of the link between maternal prenatal stress and child sleep problems should be continued and extended to other brain areas.

RESUMO

Today, children are less active than previous generations leading to an increased prevalence of morbidity associated with physical inactivity. Globally, full-day preschool is rapidly becoming the norm. Thus, the amount of time that a child spends outside the home is an opportunity for schools and teachers to educate children about the importance of participating in physical activity and making healthy eating choices. One approach to comprehensively offer opportunities for physical activity and healthy eating is called Whole School, Whole Community, Whole Child, which intertwines academic success and promotion of healthy behaviors. Particularly for adolescent children, multicomponent approaches that include both school and family or community involvement have the most significant potential to make meaningful differences in the rate of physical activity participation. For young children, teacher training, resources, and equipment are needed to achieve equity across programs and schools, because these are predictors of physical activity participation. Further, school policies, administrative support, modeling by teachers, and the use of cues and incentives can have a positive effect. The purpose of this paper is to describe the benefits of contemporary, evidence-based models for providing opportunities for health behaviors in school from early childhood to adolescence.

RESUMO

INTRODUCTION: Life expectancy in the US is 78.6 years, and although people are living longer, they are also living with chronic diseases. As women age, they are more susceptible to chronic disease including mental health conditions and Alzheimer's Disease (AD) dementia. Therefore, practical and cost effective ways to prevent the onset of cognitive, mental and physical ailments and increase the quality of life among aging populations is timely and warranted. The purpose of this study in aging adult women was to explore if prayer is associated with electrical brain activity patterns consistent with meditation and therefore a likely pro-health behavior. MATERIALS AND METHODS: A sample of 33 healthy women (Mage = 80.1, SD = 8.3) were recruited from a Midwestern Catholic Sisters community. Participants completed 6 consecutive, counterbalanced electroencephalogram (EEG) sessions: three resting sessions and three praying sessions equating to 18 min of recorded EEG data for each participant. Differences in alpha power and frontal alpha asymmetry (FAA) between praying and resting conditions and the influence of age on the association between inter-individual differences in alpha power were explored. RESULTS: Results indicated significant higher alpha power detected in electrodes positioned in the occipital area for praying sessions compared to resting sessions. Additionally, we found significant positive correlations between FAA values and age of the participants for both conditions (rest: r = 0.436, p = 0.016; pray: r = 0.434, p = 0.017), indicating more approach-related brain activity in older participants. CONCLUSIONS: Taken collectively, our results suggest that prayerful meditation increased alpha power and that positive and approach-related (left frontal-central) brain activity increased as Sisters aged. Future studies should explore the mediating role of age as it relates to meditation and cognitive outcomes.

RESUMO

Purpose: Fitness education is essential for children's health, but determining the effectiveness of instruction related to health-related fitness is difficult. The present study developed and confirmed the validity of a 20-item scale, adapted from the School Health Index (Centers for Diseases Control and Prevention [CDC], 2014), to evaluate the success of fitness education portion of the Presidential Youth Fitness Program (PYFP) across a sample of 785 teachers. Method: The initial subset (n = 373) represented 353 schools and was used for conducting an exploratory factor analysis. The second subset (n = 412) representing 404 schools, was used to conduct the confirmatory factor analysis. Teachers self-assessed their perceived degree of implementation of fitness education (full, partial, under development, not in place) within their school (i.e., teachers helped students set fitness goals). Results: An initial exploratory factor analysis revealed that the Fitness Education Index questions clustered into six factors. A subsequent confirmatory factor analysis conducted using Mplus concluded the six-factor solution was a good fit (CFI = 0.90, TLI = 0.88, RMSEA = 0.08, SRMR = 0.06). Conclusion: This scale is a valid measure of a school's readiness to initiate and track progress toward the full implementation of fitness education.
