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BACKGROUND: In February 2022, Massachusetts rescinded a statewide universal masking policy in public schools, and many Massachusetts school districts lifted masking requirements during the subsequent weeks.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 RESULTS: Before the statewide masking policy was rescinded, trends in the incidence of Covid-19 were similar across school districts. During the 15 weeks after the statewide masking policy was rescinded, the lifting of masking requirements was associated with an additional 44.9 cases per 1000 students and staff (95% confidence interval, 32.6 to 57.1), which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.

A peer-led walking intervention for adolescent girls (the WISH study): a cluster-randomised controlled trial.

BACKGROUND: Adolescent girls in the UK and Ireland fail to meet physical activity (PA) guidelines. PA behaviours track from childhood into adulthood. The effects of walking interventions on adult health are known; however, the potential of walking to promote PA in adolescents is less known. This study evaluated the effectiveness of a novel, school-based walking intervention aimed at increasing PA levels of adolescent girls. METHODS: In this cluster-randomised controlled trial, female pupils aged 12-14 years were recruited from 18 (mixed or single-sex) schools across the border region of Ireland and Northern Ireland. Schools were randomly assigned to either the control group (usual physical activity; n=9) or the intervention group (n=9) by independent faculty staff using an online randomisation tool (randomization.com). In intervention schools, female pupils aged 15-18 years were trained as walk leaders and led the younger pupils in 10-15 min walks before school, at break, and at lunchtime. Walks were in school grounds and pupils were encouraged to join as many walks as possible. The intervention was delivered for a full school year excluding holidays (for a total of 18-21 weeks). Accelerometers measured PA, and the primary outcome was total PA (counts per minute [cpm]). Ethics approval was granted by Ulster University Research Ethics Committee and written informed consent (parent or guardian) and assent (pupils) was obtained. This study is registered with the ISRCTN Registry, 12847782. FINDINGS: The study took place from Sept 1, 2021, to May 31, 2023. In total, 589 pupils were recruited (n=286 in intervention group; n=303 in control group). Median moderate-vigorous PA (MVPA) at baseline was 36·1 min/day (IQR 23·0) for the intervention group and 35·3 min/day (19·8) for the control group. Only 37 (15%) girls in the intervention group and 29 (10%) girls in the control group met PA guidelines (60 min/day of MVPA). The mean total PA after intervention was 676 cpm (SD 18·7) for the intervention group and 710 cpm (SD 17·7) for the control group. Post-intervention total PA did not differ between groups when adjusted for age, body-mass index, z-scores, and baseline PA (mean difference -33·5, 95% CI -21·2 to 88·1; p=0·213). INTERPRETATION: Scaling up PA interventions is challenging. Despite a promising feasibility study, the results of this fully powered trial indicate that in this context, the walking programme did not increase PA. Since the COVID-19 pandemic, school environments have changed, and although pupils enjoyed the programme, attendance at walks was low. There is a need to better understand the implementation of interventions such as this within schools. FUNDING: Cross-border Healthcare Intervention Trials in Ireland Network (CHITIN).

Impact of a school-based water and hygiene intervention on child health and school attendance in Addis Ababa, Ethiopia: a cluster-randomised controlled trial.

BACKGROUND: School-based water, sanitation and hygiene (WASH) may improve the health and attendance of schoolchildren, particularly post-menarcheal girls, but existing evidence is mixed. We examined the impact of an urban school-based WASH programme (Project WISE) on child health and attendance. METHODS: The WISE cluster-randomised trial, conducted in 60 public primary schools in Addis Ababa, Ethiopia over one academic year, enrolled 2-4 randomly selected classes per school (~ 100 pupils) from grades 2 to 8 (aged 7-16) in an 'open cohort'. Schools were assigned 1:1 by stratified randomisation to receive the intervention during the 2021/2022 or the 2022/2023 academic year (waitlist control). The intervention included improvements to drinking water storage, filtration and access, handwashing stations and behaviour change promotion. Planned sanitation improvements were not realised. At four unannounced classroom visits post-intervention (March-June 2022), enumerators recorded primary outcomes of roll-call absence, and pupil-reported respiratory illness and diarrhoea in the past 7 days among pupils present. Analysis was by intention-to-treat. RESULTS: Of 83 eligible schools, 60 were randomly selected and assigned. In total, 6229 eligible pupils were enrolled (median per school 101.5; IQR 94-112), 5987 enrolled at study initiation (23rd November-22nd December 2021) and the remaining 242 during follow-up. Data were available on roll-call absence for 6166 pupils (99.0%), and pupil-reported illness for 6145 pupils (98.6%). We observed a 16% relative reduction in odds of pupil-reported respiratory illness in the past 7 days during follow-up in intervention vs. control schools (aOR 0.84; 95% CI 0.71-1.00; p = 0.046). There was no evidence of effect on pupil-reported diarrhoea in the past 7 days (aOR 1.15; 95% CI 0.84-1.59; p = 0.39) nor roll-call absence (aOR 1.07; 95% 0.83-1.38; p = 0.59). There was a small increase in menstrual care self-efficacy (aMD 3.32 on 0-100 scale; 95% CI 0.05-6.59), and no evidence of effects on other secondary outcomes. CONCLUSIONS: This large-scale intervention to improve school WASH conditions city-wide had a borderline impact on pupil-reported respiratory illness but no effect on diarrhoeal disease nor pupil absence. Future research should establish relationships between WASH-related illness, absence and other educational outcomes. TRIAL REGISTRATION: ClinicalTrials.gov, number NCT05024890.

Implementation and Performance of a Point-of-Care COVID-19 Test Program in 4000 California Schools.

OBJECTIVE: To evaluate the feasibility and accuracy of an unprecedented COVID-19 antigen testing program in schools, which required a healthcare provider order, laboratory director, a Clinical Laboratory Improvement Amendments certificate of waiver, as well as training of school personnel. STUDY DESIGN: Descriptive report of a point-of-care, school-based antigen testing program in California from August 1st, 2021 through May 30, 2022, in which participants grades K-12 self-swabbed and school personnel performed testing. Participants included 944 009 students, personnel, and community members from 4022 California kindergarten through high schools. Outcomes measured include sensitivity and specificity (with polymerase chain reaction [PCR] as comparator) of the Abbott BinaxNOW antigen test, number of tests performed, and active infections identified. RESULTS: Of 102 022 paired PCR/antigen tests, the overall sensitivity and specificity for the antigen test was 81.2% (95% CI: 80.5%-81.8%) and 99.6% (95% CI: 99.5%-99.6%), respectively, using cycle threshold values <30. During January through March 2022, the highest prevalence period, the positive predictive value of antigen testing was 94.7% and the negative predictive value was 94.2%. Overall, 4022 school sites were enrolled and 3 987 840 million antigen tests were performed on 944 009 individuals. A total of 162 927 positive antigen tests were reported in 135 163 individuals (14.3% of persons tested). CONCLUSIONS: Rapidly implementing a school-based testing program in thousands of schools is feasible. Self-swabbing and testing by school personnel can yield accurate results. On-site COVID-19 testing is no longer necessary in schools, but this model provides a framework for future infectious disease threats.

Engaging School Champions in the Implementation of a Research Study in Historically Marginalized School Communities.

Community engagement in research improves uptake of health interventions and health outcomes among marginalized populations. Researchers from school-based health centers serving marginalized communities in Miami, Florida fostered community engagement in COVID-19 research and health education through collaboration with school staff and student "champions" from June 2021 to June 2023. Evaluations completed by champions assessed acceptability, feasibility, and recommendations for improvements. Overall satisfaction was high among champions. We elaborate on lessons learned and future directions for this type of research collaboration. (Am J Public Health. 2024;114(8):789-793. https://doi.org/10.2105/AJPH.2024.307711).

School-based healthy eating interventions for adolescents aged 10-19 years: an umbrella review.

BACKGROUND: The benefits of healthy eating are well known, yet adolescent diet is often poor. School based interventions offer a promising option to promote healthy eating, however, evidence is unclear. AIM: This umbrella review synthesised the current evidence on school-based interventions for healthy eating in adolescents (10-19 years old). METHODS: Using Joanna Briggs Institute (JBI) umbrella review guidelines, a systematic search was conducted on 11 electronic databases (PubMed, CINHAL, EMBASE, Science Direct, PsycINFO, MEDLINE, Scopus, ERIC, Web of Science, Cochrane Register of Systemic Review and JBI Evidence Synthesis) to identify reviews published between January 2000 and December 2023. Methodological quality was assessed using JBI critical appraisal tool. A narrative synthesis was conducted informed by the World Health Organisation's Health Promoting School (HPS) framework that categorises school-based interventions into three components i.e., health education, school environment changes, and family and community involvement. RESULTS: Seventeen reviews were identified (including 347 unique primary studies) that were published between 2008 and 2023. 87% of the reviews were based on interventions in high- income countries, limiting applicability to low- and middle-income countries. Fourteen reviews were rated as high, two as moderate, and one was rated as low methodological quality. Evidence from 71% of the reviews (n = 14 reviews, 13 = high methodological quality) found that multi-component interventions (i.e., interventions incorporating more than two components of the HPS framework) improved adolescents' knowledge and behaviour concerning healthy eating. At the individual level, tech-driven healthy eating curricula effectively improved eating behaviours of adolescents. These individual-level interventions proved to be more effective and sustainable when supported by system-level changes, such as modifying school environments including increased availability of healthy foods and involving parents to promote healthy eating for adolescents. However, limited evidence from only three reviews suggests mixed feasibility for technology-based interventions and lower feasibility for multi-component interventions. The lack of information on stakeholder involvement in intervention design is another critical evidence gap. CONCLUSION: School-based multi-component healthy eating interventions that combine individual-level interventions with system-level changes are effective in promoting healthy eating behaviours among adolescents. Future reviews should assess the effectiveness of participatory approaches in intervention design, feasibility and scale-up studies, and analysing evidence from low- and middle-income countries.

The effectiveness of secondary-school based interventions on the future physical activity of adolescents in Aotearoa New Zealand: a modelling study.

BACKGROUND: Secondary schools are important settings for promoting varied physical activity (PA) opportunities for adolescents to promote PA throughout life. However, research on the effect of secondary school-based interventions on future PA is limited. This study examined the potential impact of secondary school-based interventions on the determinants of future PA participation of Aotearoa New Zealand (NZ) adolescents using simulated modelling. METHODS: We used data from a nationally representative sample of secondary school students (n = 5035) aged 12-17 between 2017 and 2020 in NZ. We modelled four secondary school-based interventions and their projected impact on five determinants of future PA. Modelled interventions were the technological augmentation of physical education (TAPE), a peer-led PA mentoring programme (PL), physically active learning (PAL) and the inclusion of a natural environment play area (NE). RESULTS: Total weekly PA increased the most from the NE intervention (+ 0.2 h/week), followed by TAPE (+ 0.08 h/week), PAL (+ 0.05 h/week) and PL (-0.06 h/week). Current number of PA settings increased the most in NE (+ 1.75 settings/week), followed by TAPE (+ 1.29 settings/week), PAL (+ 1.21 settings/week) and PL (+ 0.73 settings/week). Current number of PA types increased the most in NE (+ 1.57 types/week), followed by PL (+ 1.05 types/week), TAPE (+ 0.34 types/week) and PAL (+ 0.15 types/week). Physical literacy scores increased the most from PL (+ 3.6%), followed by PAL (+ 3.3%), TAPE (+ 0.43%) and NE (+ 0.12%). Social support scores increased the most from PAL (+ 5%), followed by PL (+ 1.9%), TAPE (+ 1.46%) and NE (+ 0.57%). CONCLUSIONS: On average, all interventions benefitted determinants of future PA participation to a small degree. Results show differing magnitudes of the intervention effect by determinant, indicating the complexities surrounding the promotion of PA adherence. Future interventions could be improved through detailed consultation alongside, and involving, adolescents and stakeholders within schools. Researchers should also prioritise the collection of longitudinal PA data and explore its connection with sociodemographic differences between adolescents.

Was it a HIIT? A process evaluation of a school-based high-intensity interval training intervention.

BACKGROUND: Despite a growing body of research investigating high-intensity interval training (HIIT) in schools, there are limited process evaluations investigating their implementation. This is concerning because process evaluations are important for appropriately interpreting outcome findings and augmenting intervention design. This manuscript presents a process evaluation of Making a HIIT, a school-based HIIT intervention. METHODS: The Making a HIIT intervention spanned 8 weeks and was completed at three schools in Greater Brisbane, Australia. Ten classes (intervention group) completed 10-min teacher-led HIIT workouts at the beginning of health and physical education (HPE) lessons, and five classes (control group) continued with regular HPE lessons. The mixed methods evaluation was guided by the Framework for Effective Implementation by Durlak and DuPre. RESULTS: Program reach: Ten schools were contacted to successfully recruit three schools, from which 79% of eligible students (n = 308, x ¯ age: 13.0 ± 0.6 years, 148 girls) provided consent. Dosage: The average number of HIIT workouts provided was 10 ± 3 and the average number attended by students was 6 ± 2. Fidelity: During HIIT workouts, the percentage of time students spent at ≥ 80% of maximum heart rate (HRmax) was 55% (interquartile range (IQR): 29%-76%). Monitoring of the control group: During lessons, the intervention and control groups spent 32% (IQR: 12%-54%) and 28% (IQR: 13%-46%) of their HPE lesson at ≥ 80% of HRmax, respectively. Responsiveness: On average, students rated their enjoyment of HIIT workouts as 3.3 ± 1.1 (neutral) on a 5-point scale. Quality: Teachers found the HIIT workouts simple to implement but provided insights into the time implications of integrating them into their lessons; elements that helped facilitate their implementation; and their use within the classroom. Differentiation: Making a HIIT involved students and teachers in the co-design of HIIT workouts. Adaption: Workouts were modified due to location and weather, the complexity of exercises, and time constraints. CONCLUSION: The comprehensive evaluation of Making a HIIT provides important insights into the implementation of school-based HIIT, including encouragings findings for student enjoyment and fidelity and recommendations for improving dosage that should be considered when developing future interventions.

Development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS).

BACKGROUND: Teachers are recognized as 'key agents' for the delivery of physical activity programs and policies in schools. The aim of our study was to develop and evaluate a tool to assess teachers' capability, opportunity, and motivation to deliver school-based physical activity interventions. METHODS: The development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS) involved three phases. In Phase 1, we invited academic experts to participate in a Delphi study to rate, provide recommendations, and achieve consensus on questionnaire items that were based on the Capability, Opportunity, and Motivation Behavior (COM-B) model. Each item was ranked on the degree to which it matched the content of the COM-B model, using a 5-point scale ranging from '1 = Poor match' to '5 = Excellent match'. In Phase 2, we interviewed primary and secondary school teachers using a 'think-aloud' approach to assess their understanding of the items. In Phase 3, teachers (n = 196) completed the COM-PASS to assess structural validity using confirmatory factor analysis (CFA). RESULTS: Thirty-eight academic experts from 14 countries completed three rounds of the Delphi study. In the first round, items had an average rating score of 4.04, in the second round 4.51, and in the third (final) round 4.78. The final tool included 14 items, which related to the six constructs of the COM-B model: physical capability, psychological capability, physical opportunity, social opportunity, reflective motivation, and automatic motivation. In Phase 2, ten teachers shared their interpretation of COM-PASS via a 20-min interview, which resulted in minor changes. In Phase 3, CFA of the 3-factor model (i.e., capability, opportunity, and motivation) revealed an adequate fit to the data (χ2 = 122.6, p < .001, CFI = .945, TLI = .924, RMSEA = .066). The internal consistencies of the three subscale scores were acceptable (i.e., capability: α = .75, opportunity: α = .75, motivation: α = .81). CONCLUSION: COM-PASS is a valid and reliable tool for assessing teachers' capability, opportunity, and motivation to deliver physical activity interventions in schools. Further studies examining additional psychometric properties of the COM-PASS are warranted.

Youth participation in substance use prevention: A national profile, 2011-2019.

PURPOSE: Prevention efforts are critical to avoid the negative consequences of substance use in adolescents. This study aimed to examine national trends and sociodemographic differences in adolescents' participation in school-based substance use prevention (SUP) education, community-based SUP programs, as well as family conversations about substance use. METHODS: Publicly available data for adolescents aged 12-17 from the annual cross-sectional surveys of the National Survey on Drug Use and Health 2011-2019 were analyzed. RESULTS: Across the survey years, up to 74.9%, 12.2%, and 58.1% of adolescents reported having participated in school-based SUP education, community-based SUP programs, and family conversations about the danger of substance use in the past-year, respectively. From 2011 to 2019, statistically significant decreases were observed in adolescents' participation in school-based SUP education (OR = 0.97, 95% CI: 0.96, 0.98, p < 0.001) and community-based SUP programs (OR = 0.98, 95% CI: 0.97, 0.99, p < 0.001). Meanwhile, no significant changes were observed in adolescents' participation in family conversations about the dangers of substance use. Overall, lower levels of participation in school-based and community-based SUP programs were found in adolescents aged 16-17. Adolescents living in rural areas showed lower levels of participation in school-based SUP programs and family conversations about SUP. Racial/ethnic minority adolescents overall were less likely to participate in conversations with parents about SUP than Whites. CONCLUSIONS: Further development and implementation of developmentally appropriate, gender-specific, culturally sensitive, and contextually informed SUP programs at school, community, and family levels are needed.

Addressing critical barriers for sustainability of asthma stock inhaler policy implementation and resultant programming.

BACKGROUND: Asthma is a prevalent health concern among Illinois (IL) children, and management is significantly influenced by social determinants. There were 17 states who have adopted stock inhaler laws, but implementation varies widely. OBJECTIVE: To assess critical barriers to implementation and address sustainability of stock inhaler programming in school-based asthma care in IL. METHODS: Semistructured interviews were conducted with high asthma burden school districts in IL to assess barriers in implementing stock inhaler policies and resultant programming. Thematic analysis was performed using Atlas.ti (Scientific Software Development GmbH, Berlin, Germany) to identify and code "threats" to future sustainability. Data were synthesized and presented to stakeholders for barrier mitigation. A schematic flowchart outlining steps to support sustainability was created. RESULTS: A total of 18 interviews were conducted with key community partners across 8 IL school districts, representing rural, urban, and suburban areas. Analysis revealed 25 barriers, with several identified as "threats" to future sustainability, including liability concerns, follow-up care assurance, funding/resources, pharmacy dispensing practices, district-level readiness to change, and nurse staffing. Stakeholders formed a statewide coalition to address these barriers, increase awareness, plan evaluations, and advise on state funding allocation. A national stock inhaler toolkit tailored to school administrative needs was developed to support sustainability efforts. CONCLUSION: Strategic stakeholder and community engagement are vital for establishing and sustaining stock inhaler programs that adhere to policy mandates. Many districts face challenges initiating and maintaining such programs without critical barrier mitigation and support. Collaborative solutions are necessary to ensure effective school-based asthma management and mitigate persistent pediatric asthma health disparities.

A Provider-Focused Intervention to Increase Universal HIV Testing among Adolescents in School-Based Health Centers.

We describe a provider-focused intervention to increase universal HIV testing among adolescent users in a network of School-Based Health Centers (SBHC) and compare the rate of HIV test offer and acceptance for SBHCs with and without the HIV testing intervention. The intervention was implemented at the six largest SBHCs in the 12-site network and included system- and staff-level initiatives, including an implementation coach to support SBHC associates. Rates of HIV test offer and acceptance at six sites in the Intervention Cohort were compared to that at the six sites in a Non-Intervention Cohort which was not randomly selected but had comparable distributions by age, gender and race/ethnicity. The model showed an intervention effect for universal HIV test offer, but no overall effect for test acceptance. Analyzing the intervention effect by whether a patient had a history of sexual activity, the intervention was very effective early in its implementation at increasing test offer to those with no history of sexual activity, and late in its implementation at increasing test acceptance for those with no or unknown sexual activity. Increasing and sustaining universal HIV testing in SBHCs may benefit from using Implementation Science frameworks to guide adaptation of the intervention.

Teachers' Perceptions of the Impact of the COVID-19 Pandemic and Their Implementation of an Evidence-based HIV Prevention Program in the Bahamas.

Information on how school-based programs is implemented and sustained during crises is limited. In this study, we assessed the impact of the COVID-19 pandemic on the implementation of a HIV prevention intervention in The Bahamas. Data were collected from 139 Grade 6 teachers in 2021-2022. Teachers attended virtual training and received implementation monitoring from coordinators. On average, teachers taught 26.4 (SD = 9.2) of the 35 core activities, and 7.4 (SD = 2.4) out of 9 sessions. More than half (58.3%) of teachers completed 28 or more core activities; 69.1% covered eight or all nine sessions, which is equivalent to 80% of the HIV intervention curriculum. Almost half of the teachers (43%) reported that the pandemic negatively impacted their ability to teach the program; 72% of teachers maintained that the program remained "very important" during times of crisis. Greater self-efficacy and supports increased implementation fidelity.

Adapting Schools to Climate Change with Green, Blue, and Grey Measures in Barcelona: Study Protocol of a Mixed-Method Evaluation.

Under the framework of the Urban Innovative Actions program of the European Commission, in 2020, 11 primary schools in Barcelona were transformed into climate shelters by implementing green, blue, and grey measures. Schoolyards were also opened to the local community to be used during non-school periods. Here we present the study protocol of a mixed-method approach to evaluate the effectiveness of the interventions in terms of improving environmental quality and health for users. We evaluated school level through the following: (1) quantitative pre-post quasi-experimental study, and (2) qualitative evaluation. The quantitative study included measures of (a) environmental variables (collected via low-cost and non-low-cost sensors), (b) students' health and well-being (collected via health questionnaires, attention levels test, and systematic observations), and (c) teachers' health and well-being (collected via thermal comfort measurements and health questionnaires). The qualitative methods evaluated the perceptions about the effects of the interventions among students (using Photovoice) and teachers (through focus groups). The impact of the interventions was assessed at community level during summer non-school periods through a spontaneous ethnographic approach. Data collection started in August 2019 and ended in July 2022. The evaluation provides the opportunity to identify those solutions that worked and those that need to be improved for future experiences, as well as improve the evaluation methodology and replication for these kinds of interventions.

The Health4Life e-health intervention for modifying lifestyle risk behaviours of adolescents: secondary outcomes of a cluster randomised controlled trial.

OBJECTIVES: To investigate the effectiveness of a school-based multiple health behaviour change e-health intervention for modifying risk factors for chronic disease (secondary outcomes). STUDY DESIGN: Cluster randomised controlled trial. SETTING, PARTICIPANTS: Students (at baseline [2019]: year 7, 11-14 years old) at 71 Australian public, independent, and Catholic schools. INTERVENTION: Health4Life: an e-health school-based multiple health behaviour change intervention for reducing increases in the six major behavioural risk factors for chronic disease: physical inactivity, poor diet, excessive recreational screen time, poor sleep, and use of alcohol and tobacco. It comprises six online video modules during health education class and a smartphone app. MAIN OUTCOME MEASURES: Comparison of Health4Life and usual health education with respect to their impact on changes in twelve secondary outcomes related to the six behavioural risk factors, assessed in surveys at baseline, immediately after the intervention, and 12 and 24 months after the intervention: binge drinking, discretionary food consumption risk, inadequate fruit and vegetable intake, difficulty falling asleep, and light physical activity frequency (categorical); tobacco smoking frequency, alcohol drinking frequency, alcohol-related harm, daytime sleepiness, and time spent watching television and using electronic devices (continuous). RESULTS: A total of 6640 year 7 students completed the baseline survey (Health4Life: 3610; control: 3030); 6454 (97.2%) completed at least one follow-up survey, 5698 (85.8%) two or more follow-up surveys. Health4Life was not statistically more effective than usual school health education for influencing changes in any of the twelve outcomes over 24 months; for example: fruit intake inadequate: odds ratio [OR], 1.08 (95% confidence interval [CI], 0.57-2.05); vegetable intake inadequate: OR, 0.97 (95% CI, 0.64-1.47); increased light physical activity: OR, 1.00 (95% CI, 0.72-1.38); tobacco use frequency: relative difference, 0.03 (95% CI, -0.58 to 0.64) days per 30 days; alcohol use frequency: relative difference, -0.34 (95% CI, -1.16 to 0.49) days per 30 days; device use time: relative difference, -0.07 (95% CI, -0.29 to 0.16) hours per day. CONCLUSIONS: Health4Life was not more effective than usual school year 7 health education for modifying adolescent risk factors for chronic disease. Future e-health multiple health behaviour change intervention research should examine the timing and length of the intervention, as well as increasing the number of engagement strategies (eg, goal setting) during the intervention.

Evaluating the implementation of a community health worker-delivered intervention integrating asthma care in West Philadelphia public schools.

OBJECTIVE: Schools are an important setting because students spend much of their time in school and engage in physical activity during the school day that could exacerbate asthma symptoms. Our objective is to understand the barriers and facilitators to implementing an experimental community health worker-delivered care coordination program for students with asthma within the context of the West Philadelphia Controls Asthma study. METHODS: Surveys (n = 256) and semi-structured interviews (n = 41) were completed with principals, teachers, nurses, and community health workers from 21 public and charter schools in West Philadelphia between January 2019 and September 2021. Survey participants completed the Evidence Based Practice Attitudes Scale, the Implementation Leadership Scale, and Organizational Climate Index. Semi-structured qualitative interview guides were developed, informed by the Consolidated Framework for Implementation Research. RESULTS: Participant responses indicate that they perceived benefits for schools and students related to the community health worker-based care coordination program. Several barriers and facilitators to implementing the program were noted, including challenges associated with incorporating the program into school nurse workflow, environmental triggers in the school environment, and challenges communicating with family members. An important facilitator that was identified was having supportive school administrators and staff who were engaged and saw the benefits of the program. CONCLUSIONS: This work can inform implementation planning for other locales interested in implementing community-based pediatric asthma control programs delivered by community health workers in schools.

Feasibility study of a telehealth school-based behavioral parent training group program for attention-deficit/hyperactivity disorder.

OBJECTIVE: To evaluate the feasibility and preliminary efficacy of Telehealth Behavioral Parent Training (T-BPT), a school telehealth group intervention for attention-deficit/hyperactivity disorder (ADHD) with a companion training program for school clinicians. METHODS: T-BPT was developed in an iterative three-phase design in partnership with community stakeholders during the COVID-19 pandemic. School clinicians (N = 4) delivered T-BPT over 8 weeks to parents (N = 21, groups of 5-6 per school) of children (Grades 2-5) with ADHD while simultaneously receiving training and consultation from PhD-level study trainers. A single-arm open trial was used to assess feasibility, engagement, and preliminary efficacy. RESULTS: Parents and school clinicians endorsed high feasibility, acceptability, and usability of T-BPT. Parent attendance was high (M = 94.6%) and a majority of parents (66.7%) attended all eight sessions. Preliminary outcomes indicate moderate to large reductions in parent-reported ADHD symptoms (ω2 = .36), functional and clinical global impairment (ω2s= .21 and .19, respectively), and distance learning challenges (ω2 = .22). CONCLUSIONS: Results were in line with in-person delivery, indicating promising feasibility of school telehealth BPT groups. This study also provided further support for the feasibility of the remote training model for school clinicians. Implications of the commonly endorsed barriers and benefits beyond COVID-19 and relevance to under resourced communities are also discussed.

The Modeled Cost-Effectiveness of a Prevention Program Targeting Both Eating Disorders and High BMI.

OBJECTIVE: Prevention programs for eating disorders (EDs) and high body index mass (BMI) have the potential to reduce the onset of these interconnected public health concerns. However, it remains unclear whether routine implementation of such programs would be cost-effective. This study aims to determine the cost-effectiveness of an intervention that aims to prevent both ED and high BMI. METHOD: A Markov model was developed to evaluate the incremental cost-effectiveness of a targeted school-based program, Healthy Weight, that aims to prevent both EDs and high BMI among Australian adolescents with body image concerns (aged 15-18 years), versus a "no intervention" comparator. A cost-utility analysis was conducted from a "healthcare and education" sector perspective with costs (measured in 2019 Australian dollars) and health impacts modeled over the lifetime of the target population. An incremental cost-effectiveness ratio (ICER), expressed as cost per health-adjusted life year (HALY) gained, was calculated. Sensitivity analyses were done to test model assumptions. RESULTS: The mean intervention cost and HALYs gained were AUD$2.13 million (95% CI, AUD$1.83-2.43 million) and 146 (95% CI, 90-209), respectively. With healthcare cost-savings (AUD$3.97 million) included, the intervention was predicted to be cost-saving (AUD$1.83 million; 95% CI, AUD$0.51-3.21 million). Primary findings were robust to extensive sensitivity analyses. DISCUSSION: The Healthy Weight intervention is likely to represent good value-for-money. To ensure the successful implementation of this program at the population level, further research on its feasibility and acceptability among schools and the wider community is required.

A cluster randomized controlled trial comparing the effectiveness of two school-based interventions for autistic youth with anxiety.

BACKGROUND: Recent systematic reviews have indicated that cognitive behavioral therapy (CBT) is effective in reducing anxiety symptoms for autistic and non-autistic children. However, the vast majority of CBT research for autistic youth has been implemented within university settings and primarily by mental health providers. Schools hold great promise to equitably manage the mental health symptoms of autistic youth. Although preliminary research evaluating CBT within schools has been promising, CBT has not yet been compared to another readily available school mental health program. The goal of this protocol paper is to describe a multi-site study comparing two school-based interventions, Facing Your Fears-School Based (FYF-SB) and Zones of Regulation (ZOR) via a cluster randomized controlled type 1 hybrid effectiveness-implementation trial to determine which of the two interventions will best support autistic youth with anxiety in schools. METHODS: Up to 100 elementary and middle schools will be randomized into FYF-SB or ZOR. Once schools are randomized, a minimum of two interdisciplinary school providers at each school will be trained to deliver either FYF-SB or ZOR over the course of 12 weeks to groups of 2-5 autistic students ages 8-14 years. Over the course of two years, a total of 200 autistic students will receive either ZOR or FYF-SB. The primary outcome of this trial is child anxiety, as rated by masked evaluators and via caregiver- and student-report, which will be measured at baseline, post-treatment, and 6-month follow-up. Semi-structured interviews will also be conducted with a purposive sample of students, caregivers, and school providers to understand the acceptability, appropriateness, and feasibility of either ZOR or FYF-SB. Stakeholder engagement is a central component of this project via two stakeholder advisory boards that will directly inform and oversee the project. DISCUSSION: Results of this study will provide evidence about the relative impact of two school-based mental health interventions on outcomes reported as meaningful by caregivers and school providers. The additional focus on evaluating factors that support the implementation of FYF-SB and ZOR will allow future studies to test targeted implementation strategies that support mental health programming uptake and implementation within public schools. TRIAL REGISTRATION: This trial is registered with clinicaltrials.gov (NCT05863520).

Implementation and effectiveness of a school-based intervention to increase adherence to national school meal guidelines: a non-randomised controlled trial.

OBJECTIVE: Implementation of school meal guidelines is often inadequate, and evidence for effective implementation strategies for school-based nutrition interventions is limited. The aim of the present study was to examine the implementation and effectiveness of a multi-strategy implementation intervention to increase adherence to the Norwegian national school meal guideline. DESIGN: The study was a school-based hybrid implementation effectiveness trial with a pre-post non-equivalent control group design, testing three implementation strategies: internal facilitation, training and an educational meeting. SETTING: Primary schools and after-school services in two counties in south-east Norway. PARTICIPANTS: School principals, after-school leaders and class teachers from thirty-three schools in the intervention county and principals and after-school leaders from thirty-four schools in a comparison county. RESULTS: There was a significant difference of 4 percentage points in change scores between the intervention and the comparison groups at follow-up, after adjusting for baseline adherence (B = 0·04, seB = 0·01, t = 3·10, P = 0·003). The intervention effect was not associated with the school's socio-economic profile. School-level fidelity was the implementation dimension that was most strongly correlated (r s = 0·48) with the change scores in the intervention group, indicating that principals' support is important for gaining the largest intervention effects. CONCLUSIONS: A school-based intervention with low intensity, based on trained teachers as internal facilitators, can increase adherence to the national school meal guideline among Norwegian primary schools, irrespective of local socio-economic conditions. Implementation fidelity, at an organisational level, may be a useful predictor for intervention outcomes in schools.
