Measures implemented in the school setting to contain the COVID-19 pandemic.

BACKGROUND: More than 767 million coronavirus 2019 (COVID-19) cases and 6.9 million deaths with COVID-19 have been recorded as of August 2023. Several public health and social measures were implemented in schools to contain the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and prevent onward transmission. We built upon methods from a previous Cochrane review to capture current empirical evidence relating to the effectiveness of school measures to limit SARS-CoV-2 transmission. OBJECTIVES: To provide an updated assessment of the evidence on the effectiveness of measures implemented in the school setting to keep schools open safely during the COVID-19 pandemic. SEARCH METHODS: We searched the Cochrane COVID-19 Study Register, Educational Resources Information Center, World Health Organization (WHO) COVID-19 Global literature on coronavirus disease database, and the US Department of Veterans Affairs Evidence Synthesis Program COVID-19 Evidence Reviews on 18 February 2022. SELECTION CRITERIA: Eligible studies focused on measures implemented in the school setting to contain the COVID-19 pandemic, among students (aged 4 to 18 years) or individuals relating to the school, or both. We categorized studies that reported quantitative measures of intervention effectiveness, and studies that assessed the performance of surveillance measures as either 'main' or 'supporting' studies based on design and approach to handling key confounders. We were interested in transmission-related outcomes and intended or unintended consequences. DATA COLLECTION AND ANALYSIS: Two review authors screened titles, abstracts and full texts. We extracted minimal data for supporting studies. For main studies, one review author extracted comprehensive data and assessed risk of bias, which a second author checked. We narratively synthesized findings for each intervention-comparator-outcome category (body of evidence). Two review authors assessed certainty of evidence. MAIN RESULTS: The 15 main studies consisted of measures to reduce contacts (4 studies), make contacts safer (7 studies), surveillance and response measures (6 studies; 1 assessed transmission outcomes, 5 assessed performance of surveillance measures), and multicomponent measures (1 study). These main studies assessed outcomes in the school population (12), general population (2), and adults living with a school-attending child (1). Settings included K-12 (kindergarten to grade 12; 9 studies), secondary (3 studies), and K-8 (kindergarten to grade 8; 1 study) schools. Two studies did not clearly report settings. Studies measured transmission-related outcomes (10), performance of surveillance measures (5), and intended and unintended consequences (4). The 15 main studies were based in the WHO Regions of the Americas (12), and the WHO European Region (3). Comparators were more versus less intense measures, single versus multicomponent measures, and measures versus no measures. We organized results into relevant bodies of evidence, or groups of studies relating to the same 'intervention-comparator-outcome' categories. Across all bodies of evidence, certainty of evidence ratings limit our confidence in findings. Where we describe an effect as 'beneficial', the direction of the point estimate of the effect favours the intervention; a 'harmful' effect does not favour the intervention and 'null' shows no effect either way. Measures to reduce contact (4 studies) We grouped studies into 21 bodies of evidence: moderate- (10 bodies), low- (3 bodies), or very low-certainty evidence (8 bodies). The evidence was very low to moderate certainty for beneficial effects of remote versus in-person or hybrid teaching on transmission in the general population. For students and staff, mostly harmful effects were observed when more students participated in remote teaching. Moderate-certainty evidence showed that in the general population there was probably no effect on deaths and a beneficial effect on hospitalizations for remote versus in-person teaching, but no effect for remote versus hybrid teaching. The effects of hybrid teaching, a combination of in-person and remote teaching, were mixed. Very low-certainty evidence showed that there may have been a harmful effect on risk of infection among adults living with a school student for closing playgrounds and cafeterias, a null effect for keeping the same teacher, and a beneficial effect for cancelling extracurricular activities, keeping the same students together and restricting entry for parents and caregivers. Measures to make contact safer (7 studies) We grouped studies into eight bodies of evidence: moderate- (5 bodies), and low-certainty evidence (3 bodies). Low-certainty evidence showed that there may have been a beneficial effect of mask mandates on transmission-related outcomes. Moderate-certainty evidence showed full mandates were probably more beneficial than partial or no mandates. Evidence of a beneficial effect of physical distancing on risk of infection among staff and students was mixed. Moderate-certainty evidence showed that ventilation measures probably reduce cases among staff and students. One study (very low-certainty evidence) found that there may be a beneficial effect of not sharing supplies and increasing desk space on risk of infection for adults living with a school student, but showed there may be a harmful effect of desk shields. Surveillance and response measures (6 studies) We grouped studies into seven bodies of evidence: moderate- (3 bodies), low- (1 body), and very low-certainty evidence (3 bodies). Daily testing strategies to replace or reduce quarantine probably helped to reduce missed school days and decrease the proportion of asymptomatic school contacts testing positive (moderate-certainty evidence). For studies that assessed the performance of surveillance measures, the proportion of cases detected by rapid antigen detection testing ranged from 28.6% to 95.8%, positive predictive value ranged from 24.0% to 100.0% (very low-certainty evidence). There was probably no onward transmission from contacts of a positive case (moderate-certainty evidence) and replacing or shortening quarantine with testing may have reduced missed school days (low-certainty evidence). Multicomponent measures (1 study) Combining multiple measures may have led to a reduction in risk of infection among adults living with a student (very low-certainty evidence). AUTHORS' CONCLUSIONS: A range of measures can have a beneficial effect on transmission-related outcomes, healthcare utilization and school attendance. We rated the current findings at a higher level of certainty than the original review. Further high-quality research into school measures to control SARS-CoV-2 in a wider variety of contexts is needed to develop a more evidence-based understanding of how to keep schools open safely during COVID-19 or a similar public health emergency.

Standards of care and determinants of women's satisfaction with delivery services in Nepal: a multi-perspective analysis using data from a health facility-based survey.

BACKGROUND: Compliance with standards of care is required for sustained improvement in the quality of delivery services. It thus represents a key challenge to improving maternal survival and meeting the Sustainable Development Goal (SDG) target of reducing the maternal mortality ratio to 70 deaths per 100,000 live births. This study examines the extent to which normal low-risk health facility deliveries in Nepal meet the standards of quality of care and assesses the effect of the standards of quality of care and various contextual factors on women's satisfaction with the services they receive. METHODS: Drawing on the 2021 Nepal Health Facility Survey, the sample comprised 320 women who used health facilities for normal, low-risk delivery services. A weighted one-sample t-test was applied to examine the proportion of deliveries meeting the eight standards of care. Women's overall satisfaction level was computed from seven satisfaction variables measured on a Likert scale, using principal component analysis. The composite measure was then dichotomized. Binary logistic regression was used to analyze the determinants of women's satisfaction with delivery care services. RESULTS: Deliveries complying with the eight standards of care and its 53 indicators varied widely; output indicators were more frequently met than input indicators. Of the eight standards of care, the "functional referral system" performed highest (92.0%), while "competent, motivated human resources" performed the least (52.4%). Women who were attended by a provider when they called for support (AOR: 5.29; CI: 1.18, 23.64), who delivered in health facilities that displayed health statistics (AOR 3.16; CI: 1.87, 5.33), who experienced caring behaviors from providers (AOR: 2.59; CI: 1.06, 6.30) and who enjoyed audio-visual privacy (AOR 2.13; CI: 1.04, 4.38) had higher satisfaction levels compared to their counterparts. The implementation of the Maternity Incentive Scheme and presence of a maternal waiting room in health facilities, however, were associated with lower satisfaction levels. CONCLUSIONS: Nepal performed moderately well in meeting the standards of care for normal, low-risk deliveries. To meet the SDG target Nepal must accelerate progress. It needs to focus on people-centered quality improvement to routinely assess the standards of care, mobilize available resources, improve coordination among the three tiers of government, and implement high-impact programs.

Changes in health facility readiness for obstetric and neonatal care services in Nepal: an analysis of cross-sectional health facility survey data in 2015 and 2021.

BACKGROUND: Nepal is committed to achieving the Sustainable Development Goal (SDG) 2030 target 3.1 of reducing the maternal mortality ratio to 70 deaths per 100,000 live births. Along with increasing access to health facility (HF)-based delivery services, improving HF readiness is critically important. The majority of births in Nepal are normal low-risk births and most of them take place in public HFs, as does the majority of maternal deaths. This study aims to assess changes in HF readiness in Nepal between 2015 and 2021, notably, if HF readiness for providing high-quality services for normal low-risk deliveries improved; if the functionality of basic emergency obstetric and neonatal care (BEmONC) services increased; and if infection prevention and control improved. METHODS: Cross-sectional data from two nationally representative HF-based surveys in 2015 and 2021 were analyzed. This included 457 HFs in 2015 and 804 HFs in 2021, providing normal low-risk delivery services. Indices for HF readiness for normal low-risk delivery services, BEmONC service functionality, and infection prevention and control were computed. Independent sample T-test was used to measure changes over time. The results were stratified by public versus private HFs. RESULTS: Despite a statistically significant increase in the overall HF readiness index for normal low-risk delivery services, from 37.9% in 2015 to 43.7%, in 2021, HF readiness in 2021 remained inadequate. The availability of trained providers, essential medicines for mothers, and basic equipment and supplies was high, while that of essential medicines for newborns was moderate; availability of delivery care guidelines was low. BEmONC service functionality did not improve and remained below five percent facility coverage at both time points. In private HFs, readiness for good quality obstetrical care was higher than in public HFs at both time points. The infection prevention and control index improved over time; however, facility coverage in 2021 remained below ten percent. CONCLUSIONS: The slow progress and sub-optimal readiness for normal, low-risk deliveries and infection prevention and control, along with declining and low BEmONC service functionality in 2021 is reflective of poor quality of care and provides some proximate explanation for the moderately high maternal mortality and the stagnation of neonatal mortality in Nepal. To reach the SDG 2030 target of reducing maternal deaths, Nepal must hasten its efforts to strengthen supply chain systems to enhance the availability and utilization of essential medicines, equipment, and supplies, along with guidelines, to bolster the human resource capacity, and to implement mechanisms to monitor quality of care. In general, the capacity of local governments to deliver basic healthcare services needs to be increased.

Cinemeducation: A mixed methods study on learning through reflective thinking, perspective taking and emotional narratives.

INTRODUCTION: Cinemeducation describes the use of film in medical education. The M23 Cinema (M23C) comprises a film screening and subsequent discussion with experts, affected persons and the audience. Previous research suggests that participating in cinemeducation may affect emotions and attitudes. This study aimed to establish a conceptual framework and explore when learning takes place, how learning occurs and what participants learn during the M23C. METHODS: Informed by focused literature searches, discussions of the authors and the research results, a conceptual framework of the M23C was developed, comprising three dimensions (five distinct phases, learning methodology and potential impact). A mixed method study was undertaken, employing an exploratory sequential design. Initially, the qualitative component was conducted by interviewing everyone involved, comprising focus groups, expert interviews, a group interview and one narrative interview. All qualitative data were analysed using qualitative content analysis. The qualitative findings were used to inform the development of a survey among the participants of M23C evenings. The survey results were analysed descriptively. The findings generated by both data sets were integrated using the "following a thread" protocol and visualised by joint displays. RESULTS: In total, 15 participants in M23C courses, six members of the current and two of the former organising committee, two experts, two affected persons and the initiator of the M23C were included in the qualitative component (n = 28). A total of 503 participants responded to the survey. The qualitative data confirmed the relevance of the five phases and participants described reflective thinking, perspective taking and emotional narratives as the three dimensions of how they learned during the M23C. Participants reported a change in attitudes, enriching their knowledge, experiencing empathy and learning about other health professions. DISCUSSION: Our findings suggest that the M23C as a cinemeducation course provides a unique learning environment in the training of health professionals.

Reach and public health implications of proposed new food marketing regulation in Germany: an updated analysis.

Advertising for unhealthy foods adversely affects children's food preferences and intake. The German government published plans to restrict such advertising in February 2023 and has revised them several times since. We assess the reach of the current draft from June 2023, and discuss its public health implications. We show that across 22 product categories covered by the current draft law, the median share of products permitted for marketing to children stands at 55%, with an interquartile range of 11-73%. Resistance from industry groups and from within government poses hurdles and leaves the prospects of the legislation uncertain.

Applying the WHO-INTEGRATE evidence-to-decision framework in the development of WHO guidelines on parenting interventions: step-by-step process and lessons learnt.

BACKGROUND: Development of guidelines for public health, health system, and health policy interventions demands complex systems thinking to understand direct and indirect effects of interventions within dynamic systems. The WHO-INTEGRATE framework, an evidence-to-decision framework rooted in the norms and values of the World Health Organization (WHO), provides a structured method to assess complexities in guidelines systematically, such as the balance of an intervention's health benefits and harms and their human rights and socio-cultural acceptability. This paper provides a worked example of the application of the WHO-INTEGRATE framework in developing the WHO guidelines on parenting interventions to prevent child maltreatment, and shares reflective insights regarding the value added, challenges encountered, and lessons learnt. METHODS: The methodological approach comprised describing the intended step-by-step application of the WHO-INTEGRATE framework and gaining reflective insights from introspective sessions within the core team guiding the development of the WHO guidelines on parenting interventions and a methodological workshop. RESULTS: The WHO-INTEGRATE framework was used throughout the guideline development process. It facilitated reflective deliberation across a broad range of decision criteria and system-level aspects in the following steps: (1) scoping the guideline and defining stakeholder engagement, (2) prioritising WHO-INTEGRATE sub-criteria and guideline outcomes, (3) using research evidence to inform WHO-INTEGRATE criteria, and (4) developing and presenting recommendations informed by WHO-INTEGRATE criteria. Despite the value added, challenges, such as substantial time investment required, broad scope of prioritised sub-criteria, integration across diverse criteria, and sources of evidence and translation of insights into concise formats, were encountered. CONCLUSIONS: Application of the WHO-INTEGRATE framework was crucial in the integration of effectiveness evidence with insights into implementation and broader implications of parenting interventions, extending beyond health benefits and harms considerations and fostering a whole-of-society-perspective. The evidence reviews for prioritised WHO-INTEGRATE sub-criteria were instrumental in guiding guideline development group discussions, informing recommendations and clarifying uncertainties. This experience offers important lessons for future guideline panels and guideline methodologists using the WHO-INTEGRATE framework.

A Bayesian hierarchical approach to account for evidence and uncertainty in the modeling of infectious diseases: An application to COVID-19.

Infectious disease models can serve as critical tools to predict the development of cases and associated healthcare demand and to determine the set of nonpharmaceutical interventions (NPIs) that is most effective in slowing the spread of an infectious agent. Current approaches to estimate NPI effects typically focus on relatively short time periods and either on the number of reported cases, deaths, intensive care occupancy, or hospital occupancy as a single indicator of disease transmission. In this work, we propose a Bayesian hierarchical model that integrates multiple outcomes and complementary sources of information in the estimation of the true and unknown number of infections while accounting for time-varying underreporting and weekday-specific delays in reported cases and deaths, allowing us to estimate the number of infections on a daily basis rather than having to smooth the data. To address dynamic changes occurring over long periods of time, we account for the spread of new variants, seasonality, and time-varying differences in host susceptibility. We implement a Markov chain Monte Carlo algorithm to conduct Bayesian inference and illustrate the proposed approach with data on COVID-19 from 20 European countries. The approach shows good performance on simulated data and produces posterior predictions that show a good fit to reported cases, deaths, hospital, and intensive care occupancy.

[Participation in children's hospitals: approaches to participatory formats for paediatric patients]. / Teilhabe im Kinderkrankenhaus: Formate zur Verwirklichung des Rechts auf Partizipation von jungen Patientinnen und Patienten.

Based on the UN Convention on the Rights of the Child, children and young people have the right to participate in all matters and decisions that affect them. This applies in particular when they are patients in a children's hospital. In the international context, established formats for the participation of young patients regarding health issues already exist, for example "Children's Councils" or "Young Person's Advisory Groups". In Germany, such approaches are still mostly lacking. It thus remains important to develop suitable formats that enable meaningful and effective participation of young patients in the health system. These formats must be chosen in such a way that they can realistically be implemented in clinical settings as well as in pediatric research, and that they can be sustained in the long term. In order to strengthen the consideration of children's rights in the health system, the advancement of such participatory formats as well as their sustainable implementation and evaluation are desirable.

Emergency obstetric and newborn care signal functions: The situation in health facilities in Nepal between 2015 and 2021.

Expanding access to facility-based delivery services and improving the functionality of emergency obstetric and neonatal care (EmONC) are important strategies toward achieving a maternal mortality ratio of 70 deaths per 100,000 live births by 2030. In this study the researchers assess signal functions at designated facilities in Nepal, using Nepal Health Facility Survey data for 2015 and 2021. The functionality of basic and comprehensive EmONC sites was low, declining over the six-year period. Lack of progress may partly be attributed to the COVID-19 pandemic. Nepal needs to expand EmONC sites strategically, strengthen referral systems, improve service readiness, and periodically assess service quality.

Interim Evaluation of Germany's Sugar Reduction Strategy for Soft Drinks: Commitments versus Actual Trends in Sugar Content and Sugar Sales from Soft Drinks.

INTRODUCTION: A high intake of sugar, in particular from sugar-sweetened soft drinks, increases the risk for obesity, type 2 diabetes mellitus, and dental caries. Germany has pursued a national strategy for sugar reduction in soft drinks based on voluntary commitments by industry since 2015, but its effects are unclear. METHODS: We use aggregated annual sales data from Euromonitor International to assess trends in mean sales-weighted sugar content of soft drinks and per capita sugar sales from soft drinks in Germany from 2015 to 2021. We compare these trends to the reduction path set by Germany's national sugar reduction strategy and to data for the United Kingdom, which adopted a soft drinks tax in 2017 and which we selected as best practice comparison country based on pre-defined criteria. RESULTS: Between 2015 and 2021, the mean sales-weighted sugar content of soft drinks sold in Germany decreased by 2% from 5.3 to 5.2 g/100 mL, falling short of an interim 9% reduction target and a 29% reduction observed in the United Kingdom over the same period. Sugar sales from soft drinks in Germany decreased from 22.4 to 21.6 g/capita/day (-4%) between 2015 and 2021 but remain high from a public health perspective. CONCLUSIONS: Reductions observed under Germany's sugar reduction strategy fall short of stated targets and trends observed internationally under best practice conditions. Additional policy measures may be needed to support sugar reduction in soft drinks in Germany.

Infrastructure, policy and regulatory interventions to increase physical activity to prevent cardiovascular diseases and diabetes: a systematic review.

BACKGROUND: Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity at a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity. METHODS: We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction. RESULTS: We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence). CONCLUSIONS: Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings. TRIAL REGISTRATION: PROSPERO 2018 CRD42018093429.

Assessing the impact of an evidence- and consensus-based guideline for controlling SARS-CoV-2 transmission in German schools on decision-making processes: a multi-component qualitative analysis.

INTRODUCTION: During the COVID-19 pandemic, decision-making on measures to reduce or prevent transmission of SARS-CoV-2 in schools was rendered difficult by a rapidly evolving and uncertain evidence base regarding their effectiveness and unintended consequences. To support decision-makers, an interdisciplinary panel of scientific experts, public health and school authorities as well as those directly affected by school measures, was convened in an unprecedented effort to develop an evidence- and consensus-based public health guideline for German schools. This study sought to assess whether and how this guideline impacted decision-making processes. METHODS: This study comprised three components: (1) we sent inquiries according to the Freedom of Information Acts of each Federal State to ministries of education, family, and health. (2) We conducted semi-structured interviews with individuals involved in decision-making regarding school measures in two Federal States, and (3) we undertook semi-structured interviews with members of the guideline panel. The content of response letters in component 1 was analysed descriptively; data for components 2 and 3 were analysed using deductive-inductive thematic qualitative content analysis according to Kuckartz. RESULTS: Responses to the Freedom of Information Act inquiries showed that the guideline was recognised as a relevant source of information by ministries of education in nine out of 16 Federal States and used as a reference to check existing directives for school measures in five Federal States. All participants (20 interviews) emphasised the value of the guideline given its evidence- and consensus-based development process but also noted limitations in its usability and usefulness, e.g., lack of context-specificity. It was consulted by participants who advised policy-makers (5 interviews) alongside other sources of evidence. Overall, perceptions regarding the guideline's impact were mixed. CONCLUSIONS: Our findings suggest that the guideline was relatively well-known in Federal States' decision-making bodies and that it was considered alongside other forms of evidence in some of these. We suggest that further research to evaluate the impact of public health guidelines on (political) decision-making is warranted. Guideline development processes may need to be adapted to account for the realities of decision-making during public health emergencies and beyond.

Developing, implementing, and monitoring tailored strategies for integrated knowledge translation in five sub-Saharan African countries.

BACKGROUND: Integrated knowledge translation (IKT) through strategic, continuous engagement with decision-makers represents an approach to bridge research, policy and practice. The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA +), comprising research institutions in Ethiopia, Malawi, Rwanda, South Africa, Uganda and Germany, developed and implemented tailored IKT strategies as part of its multifaceted research on prevention and care of non-communicable diseases and road traffic injuries. The objective of this article is to describe the CEBHA + IKT approach and report on the development, implementation and monitoring of site-specific IKT strategies. METHODS: We draw on findings derived from the mixed method IKT evaluation (conducted in 2020-2021), and undertook document analyses and a reflective survey among IKT implementers. Quantitative data were analysed descriptively and qualitative data were analysed using content analysis. The authors used the TIDieR checklist to report results in a structured manner. RESULTS: Preliminary IKT evaluation data (33 interviews with researchers and stakeholders from policy and practice, and 31 survey responses), 49 documents, and eight responses to the reflective survey informed this article. In each of the five African CEBHA + countries, a site-specific IKT strategy guided IKT implementation, tailored to the respective national context, engagement aims, research tasks, and individuals involved. IKT implementers undertook a variety of IKT activities at varying levels of engagement that targeted a broad range of decision-makers and other stakeholders, particularly during project planning, data interpretation, and output dissemination. Throughout the project, the IKT teams continued to tailor IKT strategies informally and modified the IKT approach by responding to ad hoc engagements and involving non-governmental organisations, universities, and communities. Challenges to using systematic, formalised IKT strategies arose in particular with respect to the demand on time and resources, leading to the modification of monitoring processes. CONCLUSION: Tailoring of the CEBHA + IKT approach led to the inclusion of some atypical IKT partners and to greater responsiveness to unexpected opportunities for decision-maker engagement. Benefits of using systematic IKT strategies included clarity on engagement aims, balancing of existing and new strategic partnerships, and an enhanced understanding of research context, including site-specific structures for evidence-informed decision-making.

Interventions to build resilience and to ameliorate negative psychosocial effects of the COVID-19 pandemic on children and adolescents: a systematic review and meta-analysis.

The psychosocial health of children and adolescents has been particularly affected by the COVID-19 pandemic. Containment measures have restricted social development, education and recreational activities, may have increased family conflicts and, in many cases, led to feelings of loneliness, sleep disturbances, symptoms of anxiety and depression. We conducted a systematic review to identify interventions that seek to ameliorate these detrimental effects of the COVID-19 pandemic and to build resilience in children and adolescents. Literature searches were conducted in the databases MEDLINE, EMBASE, PsycINFO, CENTRAL, WHO COVID-19 Global literature on coronavirus disease and Cochrane COVID-19 Study Register (up to 30 June 2022). The searches retrieved 9557 records of which we included 13 randomized-controlled trials (RCTs) for evidence synthesis. Included studies predominantly implemented online group sessions for school-aged children with either a psychological component, a physical activity component, or a combination of both. A meta-analysis of seven studies on anxiety and five on depressive symptoms provided evidence for a positive effect of interventions by reducing anxiety (Standardized Mean Difference (SMD) (95% CI): - 0.33 (- 0.59; - 0.06)) and depressive symptoms (SMD (95% CI): - 0.26 (- 0.36; - 0.16)) compared to the control interventions. Studies also showed improvements in positive mental health outcomes, such as resilience (n = 2) and mental and psychological wellbeing (n = 2). Exploratory subgroup analyses suggested a greater effectiveness of interventions that (i) are of higher frequency and duration, (ii) enable personal interaction (face-to-face or virtually), and (iii) include a physical activity component. Almost all studies were judged to be at high risk of bias and showed considerable heterogeneity. Further research may focus on the contribution of different intervention components or distinct subgroups and settings, and should examine children and adolescents over longer follow-up periods.

[Development of an Integrated Community-Based Prevention Strategy in Freiham (Munich) from the Perspective of the Steering Group: A Qualitative Interview Study with Social Network Analysis]. / Aufbau der Präventionskette Freiham aus Sicht des Steuerungsgremiums: Eine qualitative Interviewstudie mit Sozialer Netzwerkanalyse.

BACKGROUND: The City of Munich is planning and implementing a "Prevention Chain" as an integrated community-based prevention strategy in the new district of "Freiham" in Munich. This is taking place while the district is being built. The "Prevention Chain Freiham" aims to create an environment that enables a healthy upbringing of all children and adolescents right from the start. In order to guide this project, an interdepartmental working group was formed within the City of Munich's administration. This study analyses the working group's structures, processes and its collaboration with a variety of stakeholders. METHODS: We conducted a multimethod study comprising qualitative interviews and social network analysis. Between March and April 2018, we conducted semi-structured interviews with members of the working group. The study participants also generated ego-centred social network maps. The transcripts were analysed using qualitative content analysis as described by Schreier. The network maps were also analysed using qualitative content analysis and the results were visualized. Our preliminary findings were interpreted, discussed and validated in a workshop in June 2018 with study participants. RESULTS: Ten members of the working group participated in the study. The interdepartmental, multiprofessional collaboration in the working group was perceived as beneficial for the process of developing and implementing the Prevention Chain. The external coordination by MAGs and the scientific expertise provided by the LMU Munich were considered highly supportive. Barriers to the planning and implementation of the Prevention Chain were mainly located at administration level. Most facilitators were attributed to the collaborative processes within the working group. After having mapped all stakeholders currently involved in the Prevention Chain (mainly actors within the City of Munich's administration), additional relevant stakeholders were identified by the members of the working group. CONCLUSION: The organizational form of the working group as a formalized association of representatives of various departments that are jointly responsible for the Prevention Chain is considered beneficial for the success of the Prevention Chain. This is further supported by the external coordination and academic support. Advancing the development and implementation of the Prevention Chain will require support from all relevant departments across sectors and hierarchies.

Unintended consequences of measures implemented in the school setting to contain the COVID-19 pandemic: a scoping review.

BACKGROUND: With the emergence of SARS-CoV-2 in late 2019, governments worldwide implemented a multitude of non-pharmaceutical interventions in order to control the spread of the virus. Most countries have implemented measures within the school setting in order to reopen schools or keep them open whilst aiming to contain the spread of SARS-CoV-2. For informed decision-making on implementation, adaptation, or suspension of such measures, it is not only crucial to evaluate their effectiveness with regard to SARS-CoV-2 transmission, but also to assess their unintended consequences. OBJECTIVES: To comprehensively identify and map the evidence on the unintended health and societal consequences of school-based measures to prevent and control the spread of SARS-CoV-2. We aimed to generate a descriptive overview of the range of unintended (beneficial or harmful) consequences reported as well as the study designs that were employed to assess these outcomes. This review was designed to complement an existing Cochrane Review on the effectiveness of these measures by synthesising evidence on the implications of the broader system-level implications of school measures beyond their effects on SARS-CoV-2 transmission. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, four non-health databases, and two COVID-19 reference collections on 26 March 2021, together with reference checking, citation searching, and Google searches. SELECTION CRITERIA: We included quantitative (including mathematical modelling), qualitative, and mixed-methods studies of any design that provided evidence on any unintended consequences of measures implemented in the school setting to contain the SARS-CoV-2 pandemic. Studies had to report on at least one unintended consequence, whether beneficial or harmful, of one or more relevant measures, as conceptualised in a logic model.  DATA COLLECTION AND ANALYSIS: We screened the titles/abstracts and subsequently full texts in duplicate, with any discrepancies between review authors resolved through discussion. One review author extracted data for all included studies, with a second review author reviewing the data extraction for accuracy. The evidence was summarised narratively and graphically across four prespecified intervention categories and six prespecified categories of unintended consequences; findings were described as deriving from quantitative, qualitative, or mixed-method studies. MAIN RESULTS: Eighteen studies met our inclusion criteria. Of these, 13 used quantitative methods (3 experimental/quasi-experimental; 5 observational; 5 modelling); four used qualitative methods; and one used mixed methods. Studies looked at effects in different population groups, mainly in children and teachers. The identified interventions were assigned to four broad categories: 14 studies assessed measures to make contacts safer; four studies looked at measures to reduce contacts; six studies assessed surveillance and response measures; and one study examined multiple measures combined. Studies addressed a wide range of unintended consequences, most of them considered harmful. Eleven studies investigated educational consequences. Seven studies reported on psychosocial outcomes. Three studies each provided information on physical health and health behaviour outcomes beyond COVID-19 and environmental consequences. Two studies reported on socio-economic consequences, and no studies reported on equity and equality consequences. AUTHORS' CONCLUSIONS: We identified a heterogeneous evidence base on unintended consequences of measures implemented in the school setting to prevent and control the spread of SARS-CoV-2, and summarised the available study data narratively and graphically. Primary research better focused on specific measures and various unintended outcomes is needed to fill knowledge gaps and give a broader picture of the diverse unintended consequences of school-based measures before a more thorough evidence synthesis is warranted. The most notable lack of evidence we found was regarding psychosocial, equity, and equality outcomes. We also found a lack of research on interventions that aim to reduce the opportunity for contacts. Additionally, study investigators should provide sufficient data on contextual factors and demographics in order to ensure analyses of such are feasible, thus assisting stakeholders in making appropriate, informed decisions for their specific circumstances.

Measures implemented in the school setting to contain the COVID-19 pandemic

BACKGROUND: In response to the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the impact of coronavirus disease 2019 (COVID-19), governments have implemented a variety of measures to control the spread of the virus and the associated disease. Among these, have been measures to control the pandemic in primary and secondary school settings. OBJECTIVES: To assess the effectiveness of measures implemented in the school setting to safely reopen schools, or keep schools open, or both, during the COVID-19 pandemic, with particular focus on the different types of measures implemented in school settings and the outcomes used to measure their impacts on transmission-related outcomes, healthcare utilisation outcomes, other health outcomes as well as societal, economic, and ecological outcomes.  SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and the Educational Resources Information Center, as well as COVID-19-specific databases, including the Cochrane COVID-19 Study Register and the WHO COVID-19 Global literature on coronavirus disease (indexing preprints) on 9 December 2020. We conducted backward-citation searches with existing reviews. SELECTION CRITERIA: We considered experimental (i.e. randomised controlled trials; RCTs), quasi-experimental, observational and modelling studies assessing the effects of measures implemented in the school setting to safely reopen schools, or keep schools open, or both, during the COVID-19 pandemic. Outcome categories were (i) transmission-related outcomes (e.g. number or proportion of cases); (ii) healthcare utilisation outcomes (e.g. number or proportion of hospitalisations); (iii) other health outcomes (e.g. physical, social and mental health); and (iv) societal, economic and ecological outcomes (e.g. costs, human resources and education). We considered studies that included any population at risk of becoming infected with SARS-CoV-2 and/or developing COVID-19 disease including students, teachers, other school staff, or members of the wider community.  DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles, abstracts and full texts. One review author extracted data and critically appraised each study. One additional review author validated the extracted data. To critically appraise included studies, we used the ROBINS-I tool for quasi-experimental and observational studies, the QUADAS-2 tool for observational screening studies, and a bespoke tool for modelling studies. We synthesised findings narratively. Three review authors made an initial assessment of the certainty of evidence with GRADE, and several review authors discussed and agreed on the ratings. MAIN RESULTS: We included 38 unique studies in the analysis, comprising 33 modelling studies, three observational studies, one quasi-experimental and one experimental study with modelling components. Measures fell into four broad categories: (i) measures reducing the opportunity for contacts; (ii) measures making contacts safer; (iii) surveillance and response measures; and (iv) multicomponent measures. As comparators, we encountered the operation of schools with no measures in place, less intense measures in place, single versus multicomponent measures in place, or closure of schools. Across all intervention categories and all study designs, very low- to low-certainty evidence ratings limit our confidence in the findings. Concerns with the quality of modelling studies related to potentially inappropriate assumptions about the model structure and input parameters, and an inadequate assessment of model uncertainty. Concerns with risk of bias in observational studies related to deviations from intended interventions or missing data. Across all categories, few studies reported on implementation or described how measures were implemented. Where we describe effects as 'positive', the direction of the point estimate of the effect favours the intervention(s); 'negative' effects do not favour the intervention.  We found 23 modelling studies assessing measures reducing the opportunity for contacts (i.e. alternating attendance, reduced class size). Most of these studies assessed transmission and healthcare utilisation outcomes, and all of these studies showed a reduction in transmission (e.g. a reduction in the number or proportion of cases, reproduction number) and healthcare utilisation (i.e. fewer hospitalisations) and mixed or negative effects on societal, economic and ecological outcomes (i.e. fewer number of days spent in school). We identified 11 modelling studies and two observational studies assessing measures making contacts safer (i.e. mask wearing, cleaning, handwashing, ventilation). Five studies assessed the impact of combined measures to make contacts safer. They assessed transmission-related, healthcare utilisation, other health, and societal, economic and ecological outcomes. Most of these studies showed a reduction in transmission, and a reduction in hospitalisations; however, studies showed mixed or negative effects on societal, economic and ecological outcomes (i.e. fewer number of days spent in school). We identified 13 modelling studies and one observational study assessing surveillance and response measures, including testing and isolation, and symptomatic screening and isolation. Twelve studies focused on mass testing and isolation measures, while two looked specifically at symptom-based screening and isolation. Outcomes included transmission, healthcare utilisation, other health, and societal, economic and ecological outcomes. Most of these studies showed effects in favour of the intervention in terms of reductions in transmission and hospitalisations, however some showed mixed or negative effects on societal, economic and ecological outcomes (e.g. fewer number of days spent in school). We found three studies that reported outcomes relating to multicomponent measures, where it was not possible to disaggregate the effects of each individual intervention, including one modelling, one observational and one quasi-experimental study. These studies employed interventions, such as physical distancing, modification of school activities, testing, and exemption of high-risk students, using measures such as hand hygiene and mask wearing. Most of these studies showed a reduction in transmission, however some showed mixed or no effects.   As the majority of studies included in the review were modelling studies, there was a lack of empirical, real-world data, which meant that there were very little data on the actual implementation of interventions. AUTHORS' CONCLUSIONS: Our review suggests that a broad range of measures implemented in the school setting can have positive impacts on the transmission of SARS-CoV-2, and on healthcare utilisation outcomes related to COVID-19. The certainty of the evidence for most intervention-outcome combinations is very low, and the true effects of these measures are likely to be substantially different from those reported here. Measures implemented in the school setting may limit the number or proportion of cases and deaths, and may delay the progression of the pandemic. However, they may also lead to negative unintended consequences, such as fewer days spent in school (beyond those intended by the intervention). Further, most studies assessed the effects of a combination of interventions, which could not be disentangled to estimate their specific effects. Studies assessing measures to reduce contacts and to make contacts safer consistently predicted positive effects on transmission and healthcare utilisation, but may reduce the number of days students spent at school. Studies assessing surveillance and response measures predicted reductions in hospitalisations and school days missed due to infection or quarantine, however, there was mixed evidence on resources needed for surveillance. Evidence on multicomponent measures was mixed, mostly due to comparators. The magnitude of effects depends on multiple factors. New studies published since the original search date might heavily influence the overall conclusions and interpretation of findings for this review.

Nutrition policies in Germany: a systematic assessment with the Food Environment Policy Index.

OBJECTIVE: To systematically assess Germany's nutrition policies, to benchmark them against international best practices and to identify priority policy actions to improve population-level nutrition in Germany. DESIGN: We applied the Food Environment Policy Index (Food-EPI), a methodological framework developed by the International Network for Food and Obesity/non-communicable Diseases Research, Monitoring and Action Support (INFORMAS) network. Qualitative content analysis of laws, directives and other documents formed the basis of a multistaged, structured consultation process. SETTING: Germany. PARTICIPANTS: The expert consultation process included fifty-five experts from academia, public administration and civil society. RESULTS: Germany lags behind international best practices in several key policy areas. For eighteen policy indicators, the degree of implementation compared with international best practices was rated as very low, for twenty-one as low, for eight as intermediate and for none as high. In particular, indicators on food taxation, regulation of food marketing as well as retail and food service sector policies were rated as very low to low. Identified priority actions included the binding implementation of nutrition standards for schools and kindergartens, a reform of the value added tax on foods and beverages, a sugar-sweetened beverage tax and stricter regulation of food marketing directed at children. CONCLUSIONS: The results show that Germany makes insufficient use of the potential of evidence-informed health-promoting nutrition policies. Adopting international best practices in key policy areas could help to reduce the burden of nutrition-related chronic disease and related inequalities in nutrition and health in Germany. Implementation of relevant policies requires political leadership, a broad societal dialogue and evidence-informed advocacy by civil society, including the scientific community.

How a generally well-accepted measles vaccine mandate may lead to inequities and decreased vaccine uptake: a preregistered survey study in Germany.

BACKGROUND: In Germany, a measles vaccine mandate came into effect in March 2020, requiring proof of measles immunization for children attending kindergarten or school and for staff in a variety of facilities. Mandates can be successful if implemented with care and in a context-sensitive manner. They may, however, also lead to inequities and decreased uptake of other vaccines. The aim of this study was to investigate the acceptance and potential unintended consequences of the measles vaccine mandate in Germany. METHODS: As part of a larger evaluation project on the new mandate, we conducted an online survey among parents in August/September 2020. We assessed differences in knowledge about the mandate and the measles vaccine by socio-economic status. We used linear and logistic regression to estimate how reactance to the mandate was associated with vaccination status and vaccination intention against other diseases. We used mediation analysis to measure how trust in institutions had an impact on the attitude towards the mandate, mediated by level of reactance. RESULTS: In total, 4,863 parents participated in the study (64.2% female, mean age = 36.8 years). Of these, 74.1% endorsed a measles vaccine mandate for children. Parents with lower socio-economic status had less knowledge about the mandate and the measles vaccine. The higher parents' levels of reactance, the lower the vaccination intentions and the likelihood for the child to be vaccinated against other diseases. Furthermore, higher institutional trust decreased the level of reactance and increased positive attitudes towards the mandate (partial mediation). CONCLUSIONS: The new measles vaccine mandate in Germany, though well accepted by many, might have unintended consequences. Parents with lower socio-economic status, who know less about the mandate and vaccine, might be less likely to comply with it. The mandate may also lead to some parents omitting other childhood vaccines, as a way to restore their freedom. This could decrease vaccination coverage of other vaccines. Any potential loss of trust might provoke more reactance and lower acceptance of mandates. Policymakers should now expand communication activities on the mandate, monitor trends in vaccination coverage carefully and take measures to strengthen trust.

Development of a framework to guide research into policies promoting physical activity and healthy diets in the European context: the system-based Policy Evaluation Network (PEN) framework.

BACKGROUND: The Policy Evaluation Network (PEN) is a multidisciplinary Pan-European research consortium focussing on policies affecting dietary intake, physical activity and sedentary behaviour. At the start, the PEN consortium expressed the need for an overarching, system-based framework covering the complexities between the different domains of the policy process (design, implementation and outcomes) in order to execute all research activities in a coherent way. This article describes the PEN framework itself and its development process. METHODS: A staged approach to the development of a system-based framework was executed between February 2019 and February 2022. We started with a point-of-departure framework, made use of existing models, collected PEN outputs at different project stages (through online meetings, e-mail exchanges and workshops with PEN researchers) and drew updated versions of the framework, which resulted in the system-based PEN framework. RESULTS: The system-based PEN framework depicts the policy process as a complex system, visualizing the dynamic interrelations between and within policy domains (i.e. policy design, policy implementation and policy outcomes), the ways they interact with the context, and how to assure a focus on equity in each domain. CONCLUSIONS: The system-based PEN framework may guide researchers and professionals involved in the evaluation of health- or sustainability-related policies to consider their evaluation in a comprehensive picture, including domain interactions, contextual influences and equity considerations, as these can have important implications for the scope of their research. The stage-based process as applied for the development of the PEN framework can serve as a template for other research projects wishing to develop their own framework.
