Promoting Learning from Null or Negative Results in Prevention Science Trials.

There can be a tendency for investigators to disregard or explain away null or negative results in prevention science trials. Examples include not publicizing findings, conducting spurious subgroup analyses, or attributing the outcome post hoc to real or perceived weaknesses in trial design or intervention implementation. This is unhelpful for several reasons, not least that it skews the evidence base, contributes to research "waste", undermines respect for science, and stifles creativity in intervention development. In this paper, we identify possible policy and practice responses when interventions have null (ineffective) or negative (harmful) results, and argue that these are influenced by: the intervention itself (e.g., stage of gestation, perceived importance); trial design, conduct, and results (e.g., pattern of null/negative effects, internal and external validity); context (e.g., wider evidence base, state of policy); and individual perspectives and interests (e.g., stake in the intervention). We advance several strategies to promote more informative null or negative effect trials and enable learning from such results, focusing on changes to culture, process, intervention design, trial design, and environment.

Enablers and barriers English secondary schools face in promoting healthy diet and physical activity behaviours.

This study sought to understand the current challenges mainstream secondary schools in England face in creating a health promoting school culture for diet and physical activity behaviours. An in-depth qualitative case study of two purposely selected state-funded schools, including interviews with teachers, observations of school activities including meal breaks and a qualitative survey with parents was done. Inductive thematic analysis was used to explore emerging themes. Additional interviews with the leadership team from four further schools were used to develop and refine emerging themes. Four main themes emerged from the data: competing pressures, school environment, personnel and policy. Results demonstrate that schools recognize they have role to play in promoting healthy lifestyle behaviours to pupils; however, several significant barriers were identified such as lack of government support and regulation, school structures and organization, focus on core subjects, business-run canteens and lack of family and community engagement. Given the importance of maintaining a healthy weight throughout the life course, schools have an important role to play in creating healthy environments in which students can easily make a healthy choice. Future school promotion initiatives need to consider addressing the barriers that schools face by working with them and the communities in which they are embedded.

There has been little research done in secondary schools to understand how to promote healthy lifestyle behaviours to adolescents (secondary schools provide secondary education for students aged 11­18 years). COVID-19 has brought the importance of maintaining a healthy weight back into sharp focus and schools are an ideal setting to educate and support young people in making healthy diet and activity choices. This research sought to understand how important school staff thought creating a health-promoting culture in schools was, how they could create such a culture and what support they had or needed to do so. From interviews with school staff, observing school activities and a questionnaire to parents, we found that schools and parents believe that schools have a role to play in supporting healthy diet and physical activity behaviours although they identified many pressures that prevent making health promotion a priority; these include time and resources as well as a lack of government policy. The importance of having a head teacher with a belief in the benefits of a healthy lifestyle was recognized. The way secondary schools are structured in England makes a joined-up approach difficult and requires central planning and coordination. More support, including resources and policy commitments, are needed to support secondary schools to create a healthy school environment.

An engaged approach to exploring issues around poverty and mental health: A reflective evaluation of the research process from researchers and community partners involved in the DeStress study.

BACKGROUND: Involving patients, service users, carers and members of the public in research has been part of health policy and practice in the UK for the last 15 years. However, low-income communities tend to remain marginalized from the co-design and delivery of mental health research, perpetuating the potential for health inequalities. Greater understanding is therefore needed on how to meaningfully engage low-income communities in mental health research. OBJECTIVES: To explore and articulate whether and how an engaged research approach facilitated knowledge coproduction relating to poverty and mental distress. SETTING: A reflective evaluation of community and researcher engagement in the DeStress study that took place in two low-income areas of South-west England. DESIGN: Reflective evaluation by the authors through on-going feedback, a focus group and first-person writing and discussion on experiences of working with the DeStress project, and how knowledge coproduction was influenced by an engaged research approach. RESULTS: An engaged research approach influenced the process and delivery of the DeStress project, creating a space where community partners felt empowered to coproduce knowledge relating to poverty-related mental distress, treatment and the training of health professionals that would otherwise have been missed. We examine motivations for involvement, factors sustaining engagement, how coproduction influenced research analysis, findings and dissemination of outputs, and what involvement meant for different stakeholders. CONCLUSION: Engaged research supported the coproduction of knowledge in mental health research with low-income communities which led to multiple impacts.

Social cohesion, mental wellbeing and health-related quality of life among a cohort of social housing residents in Cornwall: a cross sectional study.

BACKGROUND: Research and policy have identified social cohesion as a potentially modifiable determinant of health and wellbeing that could contribute to more sustainable development. However, the function of social cohesion appears to vary between communities. The aim of this study was to analyse the levels of, and associations, between social cohesion, mental wellbeing, and physical and mental health-related quality of life among a cohort of social housing residents from low socioeconomic status communities in Cornwall, UK. Social housing is below market-rate rental accommodation made available to those in certain health or economic circumstances. These circumstances may impact on the form and function of social cohesion. METHODS: During recruitment, participants in the Smartline project completed the Short Warwick-Edinburgh Mental Wellbeing Scale, SF-12v2 and an eight item social cohesion scale. Cross sectional regression analyses of these data adjusted for gender, age, national identity, area socioeconomic status, rurality, education, employment, and household size were undertaken to address the study aim. RESULTS: Complete data were available from 305 (92.7%) participants in the Smartline project. Univariable analyses identified a significant association between social cohesion, mental wellbeing and mental health-related quality of life. Within fully adjusted multivariable models, social cohesion only remained significantly associated with mental wellbeing. Sensitivity analyses additionally adjusting for ethnicity and duration of residence, where there was greater missing data, did not alter the findings. CONCLUSIONS: Among a relatively homogeneous cohort, the reported level of social cohesion was only found to be significantly associated with higher mental wellbeing, not physical or mental health-related quality of life. The efforts made by social housing providers to offer social opportunities to all their residents regardless of individual physical or mental health state may support the development of a certain degree of social cohesion. Sense of control or safety in communities may be more critical to health than social cohesion. Additional observational research is needed before attempts are made to alter social cohesion to improve health.

The violence of narrative: embodying responsibility for poverty-related stress.

Narratives of self-responsibility are pervasive in neoliberally oriented contexts, and have been found to engender feelings of shame and failure amongst those affected by poverty. Here, we use findings from research in two low-income communities in south-west England to examine how these narratives become embodied within people's daily lives when they intersect with systems of welfare support and the current political drive to upscale treatment for common mental health conditions. Drawing on Bourdieu's notion of symbolic violence, we examine how narratives of self-responsibility and associated welfare reform strategies impact on the mental health of people living in economic hardship. The data show how such narratives inflict, sustain and exacerbate mental distress and suffering, and how they become naturalised and normalised by individuals themselves. We demonstrate how this situation pushes people to seek support from General Practitioners, and how clinical interactions can normalise, and in turn, medicalise, poverty-related distress. Whilst some people actively resist dominant narratives around self-responsibility, we argue that this is insufficient under broader sociocultural and political circumstances, to free themselves from the harms perpetuated by symbolic violence.

Children's Compliance With Wrist-Worn Accelerometry Within a Cluster-Randomized Controlled Trial: Findings From the Healthy Lifestyles Programme.

PURPOSE: The purpose of this study was to assess children's compliance with wrist-worn accelerometry during a randomized controlled trial and to examine whether compliance differed by allocated condition or gender. METHODS: A total of 886 children within the Healthy Lifestyles Programme trial were randomly allocated to wear a GENEActiv accelerometer at baseline and 18-month follow-up. Compliance with minimum wear-time criteria (≥10 h for 3 weekdays and 1 weekend day) was obtained for both time points. Chi-square tests were used to determine associations between compliance, group allocation, and gender. RESULTS: At baseline, 851 children had usable data, 830 (97.5%) met the minimum wear-time criteria, and 631 (74.1%) had data for 7 days at 24 hours per day. At follow-up, 789 children had usable data, 745 (94.4%) met the minimum wear-time criteria, and 528 (67%) had complete data. Compliance did not differ by gender (baseline: χ2 = 1.66, P = .2; follow-up: χ2 = 0.76, P = .4) or by group at follow-up (χ2 = 2.35, P = .13). CONCLUSION: The use of wrist-worn accelerometers and robust trial procedures resulted in high compliance at 2 time points regardless of group allocation, demonstrating the feasibility of using precise physical activity monitors to measure intervention effectiveness.

Intervention fidelity in the definitive cluster randomised controlled trial of the Healthy Lifestyles Programme (HeLP) trial: findings from the process evaluation.

BACKGROUND: The Healthy Lifestyles Programme (HeLP) was a novel school-located intervention for 9-10 year olds, designed to prevent obesity by changing patterns of child behaviour through the creation of supportive school and home environments using dynamic and creative delivery methods. This paper reports on both the quantitative and qualitative data regarding the implementation of the HeLP intervention in the definitive cluster randomised controlled trial, which was part of the wider process evaluation. METHODS: Mixed methods were used to collect data on intervention uptake, fidelity of delivery in terms of content and quality of delivery of the intervention, as well as school and child engagement with the programme. Data were collected using registers of attendance, observations and checklists, field notes, focus groups with children and semi-structured interviews with teachers. Qualitative data were analysed thematically and quantitative data were summarized using descriptive statistics. RESULTS: All 16 intervention schools received a complete or near complete programme (94-100%), which was delivered in the spirit in which it had been designed. Of the 676 children in the intervention schools, over 90% of children participated in each phase of HeLP; 92% of children across the socio-economic spectrum were deemed to be engaged with HeLP and qualitative data revealed a high level of enjoyment by all children, particularly to the interactive drama workshops. Further evidence of child engagment with the programme was demonstrated by children's clear understanding of programme messages around marketing, moderation and food labelling. Thirteen of the intervention schools were deemed to be fully engaged with HeLP and qualitative data revealed a high level of teacher 'buy in', due to the programme's compatability with the National Curriculum, level of teacher support and use of innovative and creative delivery methods by external drama practitioners. CONCLUSION: Our trial shows that it is possible to successfully scale up complex school-based interventions, engage schools and children across the socio-economic spectrum and deliver an intervention as designed. As programme integrity was maintained throughout the HeLP trial, across all intervention schools, we can be confident that the trial findings are a true reflection of the effectiveness of the intervention, enabling policy recommendations to be made. TRIAL REGISTRATION: ISRCTN15811706.

Trial baseline characteristics of a cluster randomised controlled trial of a school-located obesity prevention programme; the Healthy Lifestyles Programme (HeLP) trial.

BACKGROUND: We have developed a healthy lifestyles programme (HeLP) for primary school aged children (9-10 years), currently being evaluated in a definitive cluster randomised controlled trial. This paper descriptively presents the baseline characteristics of trial children (BMI, waist circumference, % body fat, diet and physical activity) by gender, cluster level socio-economic status, school size and time of recruitment into the trial. METHODS: Schools were recruited from across the South West of England and allocated 1:1 to either intervention (HeLP) or control (usual practice) stratified by the proportion of children eligible for free school meals (FSM, <19%, ≥19%) and school size (one Year 5 class, >1 Year 5 class). The primary outcome is change in body mass index standard deviation score (BMI sds) at 24 months post-randomisation. Secondary outcomes are BMI sds at 18 months, waist circumference and percentage body fat sds at 18 and 24 months, proportion of children classified as underweight, overweight and obese at 18 and 24 months, physical activity (for a sub-sample) and food intake at 18 months. RESULTS: At baseline 11.4% and 13.6% of children were categorised as overweight or obese respectively. A higher percentage of girls than boys (25.3% vs 24.8%) and children from schools in FSM category 2 (28.2% vs 23.2%) were overweight or obese. Children were consuming a mean (range) of 4.15 (0-13) energy dense snacks (EDS) and 3.23 (0-9) healthy snacks (HS) per day with children from schools in FSM category 2 consuming more EDS and negative food markers and less HS and positive food markers. Children spent an average 53.6 min per day (11.9 to 124.8) in MVPA and thirteen hours (779.3 min) per day (11 h to 15 h) doing less than 'light' intensity activity. Less than 5% of children achieved the Departments of Health's recommendation of 60 min of MVPA every day. CONCLUSION: We have excellent completeness of baseline data for all measures and have achieved compliance to accelerometry not seen before in other large scale studies. Our anthropometric baseline data is representative of local and national data for children this age and reflects the gender and socio-economic variations expected of children this age in relation to physical activity and weight status. TRIAL REGISTRATION: ISRCTN15811706 (1/05/2012).

Prevalence of birth defects among American-Indian births in California, 1983-2010.

BACKGROUND: Approximately 6.3 million live births and fetal deaths occurred during the ascertainment period in the California Birth Defects Monitoring Program registry. American-Indian and non-Hispanic white women delivered 40,268 and 2,044,118 births, respectively. While much information has been published about non-Hispanic white infants, little is known regarding the risks of birth defects among infants born to American-Indian women. METHODS: This study used data from the California Birth Defects Monitoring Program to explore risks of selected birth defects in offspring of American-Indian relative to non-Hispanic white women in California. The study population included all live births and fetal deaths 20 weeks or greater from 1983 to 2010. Prevalence ratios and corresponding 95% confidence intervals (CI) were computed using Poisson regression for 51 groupings of birth defects. RESULTS: Prevalence ratios were estimated for 51 groupings of birth defects. Of the 51, nine had statistically precise results ranging from 0.78 to 1.85. The eight groups with elevated risks for American-Indian births were reduction deformities of brain, anomalies of anterior segments, specified anomalies of ear, ostium secundum type atrial septal defect, specified anomalies of heart, anomalies of the aorta, anomalies of great veins, and cleft lip with cleft palate. CONCLUSION: Our results suggest that American-Indian women having babies in California may be at higher risk for eight birth defect phenotypes compared with non-Hispanic whites. Further research is needed to determine whether these risks are observed among other populations of American-Indian women or when adjusted for potential covariates.

Sleep positioning systems for children with cerebral palsy.

BACKGROUND: Sleep positioning systems can be prescribed for children with cerebral palsy to help reduce or prevent hip migration, provide comfort to ease pain and/or improve sleep. As sleep disturbance is common in children with developmental disabilities, with impact on their carers' sleep, and as sleep positioning systems can be expensive, guidance is needed to support decisions as to their use. OBJECTIVES: To determine whether commercially-available sleep positioning systems, compared with usual care, reduce or prevent hip migration in children with cerebral palsy. Any negative effect of sleep positioning systems on hip migration will be considered within this objective.Secondary objectives were to determine the effect of sleep positioning systems on: (1) number or frequency of hip problems; (2) sleep patterns and quality; (3) quality of life of the child and family; (4) pain; and (5) physical functioning. We also sought to identify any adverse effects from using sleep positioning systems. SEARCH METHODS: In December 2014, we searched CENTRAL, Ovid MEDLINE, Embase, and 13 other databases. We also searched two trials registers. We applied no restrictions on date of publication, language, publication status or study design. We checked references and contacted manufacturers and authors for potentially relevant literature, and searched the internet using Google. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) evaluating whole body sleep positioning systems for children and adolescents (up to 18 years of age) with cerebral palsy. DATA COLLECTION AND ANALYSIS: Two review authors independently screened reports retrieved from the search against pre-determined inclusion criteria and assessed the quality of eligible studies.Members of the public (parent carers of children with neurodisability) contributed to this review by suggesting the topic, refining the research objectives, interpreting the findings, and reviewing the plain language summary. MAIN RESULTS: We did not identify any randomised controlled trials that evaluated the effectiveness of sleep positioning systems on hip migration.We did find two randomised cross-over trials that met the inclusion criteria in respect of secondary objectives relating to sleep quality and pain. Neither study reported any important difference between sleeping in sleep positioning systems and not for sleep patterns or sleep quality (two studies, 21 children, very low quality evidence) and pain (one study, 11 children, very low quality evidence). These were small studies with established users of sleep positioning systems and were judged to have high risk of bias.We found no eligible trials that explored the other secondary objectives (number or frequency of hip problems, quality of life of the child and family, physical functioning, and adverse effects). AUTHORS' CONCLUSIONS: We found no randomised trials that evaluated the effectiveness of sleep positioning systems to reduce or prevent hip migration in children with cerebral palsy. Nor did we find any randomised trials that evaluated the effect of sleep positioning systems on the number or frequency of hip problems, quality of life of the child and family or on physical functioning.Limited data from two randomised trials, which evaluated the effectiveness of sleep positioning systems on sleep quality and pain for children with cerebral palsy, showed no significant differences in these aspects of health when children were using and not using a sleep positioning system.In order to inform clinical decision-making and the prescription of sleep positioning systems, more rigorous research is needed to determine effectiveness, cost-effectiveness, and the likelihood of adverse effects.

Values associated with public involvement in health and social care research: a narrative review.

BACKGROUND: Much has been written about public involvement (PI) in health and social care research, but underpinning values are rarely made explicit despite the potential for these to have significant influence on the practice and assessment of PI. OBJECTIVE: The narrative review reported here is part of a larger MRC-funded study which is producing a framework and related guidance on assessing the impact of PI in health and social care research. The review aimed to identify and characterize the range of values associated with PI that are central elements of the framework. METHODS: We undertook a review and narrative synthesis of diverse literatures of PI in health and social care research, including twenty existing reviews and twenty-four chapters in sixteen textbooks. RESULTS: Three overarching value systems were identified, each containing five value clusters. (i) A system concerned with ethical and/or political issues including value clusters associated with empowerment; change/action; accountability/transparency; rights; and ethics (normative values). (ii). A system concerned with the consequences of public involvement in research including value clusters associated with effectiveness; quality/relevance; validity/reliability; representativeness/objectivity/generalizability; and evidence (substantive values). (iii) A system concerned with the conduct of public involvement in including value clusters associated with Partnership/equality; respect/trust; openness and honesty; independence; and clarity (process values). CONCLUSION: Our review identified three systems associated with PI in health and social care research focused on normative, substantive and process values. The findings suggest that research teams should consider and make explicit the values they attach to PI in research and discuss ways in which potential tensions may be managed in order to maximize the benefits of PI for researchers, lay experts and the research.

Tailoring Healthy Workplace Interventions to Local Healthcare Settings: A Complexity Theory-Informed Workplace of Well-Being Framework.

Many healthy workplace interventions have been developed for healthcare settings to address the consistently low scores of healthcare professionals on assessments of mental and physical well-being. Complex healthcare settings present challenges for the scale-up and spread of successful interventions from one setting to another. Despite general agreement regarding the importance of the local setting in affecting intervention success across different settings, there is no consensus on what it is about a local setting that needs to be taken into account to design healthy workplace interventions appropriate for different local settings. Complexity theory principles were used to understand a workplace as a complex adaptive system and to create a framework of eight domains (system characteristics) that affect the emergence of system-level behaviour. This Workplace of Well-being (WoW) framework is responsive and adaptive to local settings and allows a shared understanding of the enablers and barriers to behaviour change by capturing local information for each of the eight domains. We use the results of applying the WoW framework to one workplace, a UK National Health Service ward, to describe the utility of this approach in informing design of setting-appropriate healthy workplace interventions that create workplaces conducive to healthy behaviour change.

UNDERSTANDING HOW HEALTHY WORKPLACES ARE CREATED: IMPLICATIONS FOR DEVELOPING A NATIONAL HEALTH SERVICE HEALTHY WORKPLACE PROGRAM.

The workplace is an important setting for promoting health and well-being. We sought to understand how successful workplace health and well-being programs were developed and implemented to inform the development of a program for a National Health Service (NHS) hospital. Case studies of successful healthy workplace programs with 34 semi-structured employee interviews informed 12 interviews with NHS staff. Interviews were thematically analyzed using Nvivo. Themes were fed back to participants for further clarification and validation. Healthy workplace programs were characterized by senior management endorsement; collective sense of ownership; presence of visible "quick wins"; and a sense that participation was easy and fun, not mandated. Programs evolved organically, allowing trust to be built and activities to be developed with employees. Interviews with NHS staff suggested a lack of belief in the possibility of change in their workplace due to time and workload pressures, and a sense of an "us and them" relationship with management, as well as environmental barriers. A consistent pattern of how the conditions for a healthy workplace can be created, which map onto the results from the NHS ward staff, suggest that without creating an enabling environment for health-promoting behaviors, workplace programs will have poor uptake and retention.

A repeated cross-sectional study examining the school impact on child weight status.

OBJECTIVE: The aim of this study is to examine whether there is a differential impact of primary schools upon children's weight status. METHODS: A repeated cross-sectional study was undertaken using five years (2006/07-2010/11) of National Child Measurement Programme data, comprising 57,976 children (aged 4-5 (Reception) and 10-11 (Year 6) years) from 300 primary schools across Devon, England. Examining each year separately, the schools were ranked according to their observed and residual (having accounted for school and neighbourhood clustering and pupil ethnicity and socioeconomic status) school mean body mass index standard deviation score (BMI-SDS). Subtracting the Reception from the Year 6 mean residuals gave 'value-added' scores for each school which were also ranked. The rankings were compared within and across the years to assess consistency. RESULTS: Although pupil BMI-SDS was high, >97% of the variation in BMI-SDS was attributable to environments other than the school. The 'value-added' by each school was only poorly correlated with the observed and residual pupil BMI-SDS; but none of the rankings were consistent across the five years. CONCLUSION: The inconsistency of the rankings and the small variation in BMI-SDS at the level of the school suggests that there is no systematic differential impact of primary schools upon pupil weight status.

Qualitative findings from an exploratory trial of the Healthy Lifestyles Programme (HeLP) and their implications for the process evaluation in the definitive trial.

BACKGROUND: Approximately one third of 10-11 year olds in England are now overweight or obese suggesting that population approaches are urgently required. However, despite the increasing number of school-based interventions to prevent obesity, results continue to be inconsistent and it is still unclear what the necessary conditions are that lead to the sustained behaviour change required to affect weight status. The Healthy Lifestyles Programme is a theoretically informed four phase multi-component intervention which seeks to create supportive school and home environments for healthy behaviours. METHODS: A process evaluation has run alongside the exploratory trial of the Healthy Lifestyles Programme to ascertain the feasibility and acceptability of; the trial design (including the trial outcomes) and the HeLP Programme and whether it is able to engage schools, children and their families. Data was collected using interviews with teachers (n = 12) and parents (n = 17) and six focus groups with children (n = 47) and a questionnaire for parents of children in the intervention schools. Interview and focus group data relating to the intervention was analysed using framework analysis. RESULTS: Four schools and 201 children participated in the exploratory trial. The data showed that the trial design was feasible and acceptable for schools and children. Three themes emerged for the data in relation to the acceptability and feasibility of the HeLP Programme (value, compatibility with the curriculum and enjoyment) and two themes emerged in relation to engagement ('knowledge and awareness' and 'taking messages on board'). The latter could be broken down into 4 subthemes ('initiating discussion with family and friends', 'acceptance of family rules', 'increased responsibility' and 'the importance of the mode and agent of delivery'). The use of highly inclusive and interactive delivery methods where the children were encouraged to identify with and take ownership of the healthy lifestyle messages were identified as important factors in motivating the children to take the messages home, seek parental support and initiate family lifestyle behaviour change. CONCLUSION: The process evaluation of the exploratory trial has not only provided evidence of the feasibility and acceptability of the Programme, it has also allowed an understanding of how HeLP engages schools, children and their families. These findings have informed the process evaluation for the definitive trial.

Charting the Characteristics of Public Health Approaches to Preventing Violence in Local Communities: A Scoping Review of Operationalised Interventions.

Interpersonal violence is a global driver of significant physical and mental ill health. Violence prevention is now a public health priority, and there have been international calls for the development of public health approaches to address this problem. This systematic scoping review identifies the scope of the literature and characteristics of operationalised public health approaches to prevent violence in communities. Synthesising what is meant by a public health approach to violence and the characteristics of operationalised approaches will assist future intervention development. Systematic searches of published sources (published following the World Health Assembly (WHA) declaration of violence as a public problem, June 1996 to April 2023 inclusive) were completed across six leading databases. For each identified approach, and reflecting a realist-informed methodology, data were extracted under the themes of major drivers, values and principles, key components, and community involvement. Of the 43 included studies, most were conducted in high-income countries and focussed on preventing weapon-related and youth violence. The studies from middle- and low-income countries also included responses to varying sexual and gender-based violence. There is a wide variety of identified characteristics, reflecting the diversity of violent behaviours public health approaches aim to impact. Approaches included focusing on changing norms and stopping violence at the individual level, to attempts to influence wider structural prevention opportunities.

Exploring the rise and diversity of health and societal issues that use a public health approach: A scoping review and narrative synthesis.

There is an increase in calls across diverse issues for a "public health approach" however, it is not clear whether there is any shared understanding in approach in its conceptualisation or implementation. Our aims were to (1) identify and categorise the issues which discuss a public health approach within published literature since 2010, (2) chart the descriptions and applications of public health approaches across and within four purposively sampled categories of issues, and (3) capture any evaluations conducted. A scoping review of published literature was undertaken; Seven leading databases were searched: AMED, APA PsycInfo, ASSIA, CINAHL complete, Cochrane Library (Review), Embase, and MEDLINE for articles published between 2010 and 2022 which have applied, described or called for a "public health approach" to address any issue. 3,573 studies were identified through our initial searches, of these 1,635 articles were recognised for possible inclusion from analysis of titles and abstract. The final number of included studies was 1,314. We identified 28 categories, 26 of which were societal issues, where a public health approach is being advocated. We purposively selected four of these categories; adverse childhood experiences; end of life care; gambling addiction and violence reduction/ knife crime for further analysis of the approach including how it was conceptualised and operationalised; less than 13% of the studies described the implementation of a public health approach and there was considerable heterogeneity across and within categories as to how this was done. Since 2010 there have been increasing calls for a public health approach to be taken to address health and societal challenges. However, the operationalisation of a public health approach varied extensively and there were few evaluations of the approach. This has implications for policy makers and those involved in commissioning related approaches in the future as the evidence-base is limited.

Lessons from a research partnership in southwest England to understand community palliative care needs in rural, coastal and low-income communities.

Background: The South West Peninsula (Cornwall, Devon, Somerset) has the highest proportion of over 65s (24.2%) and is the only English rural population with greater economic deprivation than in urban areas. Coastal populations have the worst health outcomes in England. Despite innovation among communities to support those with health and care needs in later life, recruitment to palliative care research in the region is low and there has been no evaluation of public health palliative care interventions. Objectives: A new South West Peninsula Palliative Care Research Partnership was funded for 15 months, bringing together four universities, the voluntary and community sector (including hospices) and local National Institute for Health and Care Research networks. The aim was to establish a sustainable multisectoral partnership that would identify community-based support needs for underserved rural and coastal populations by: • conducting a literature scoping review on interventions to enable community members to support the dying; • delivering a research capacity-building programme; • co-creating public and patient involvement capacity; • determining the resources and needs for communities to support dying well; • integrating findings to develop a framework of community-based support and identify future research questions; • establishing a sustainable research network infrastructure for the long-term design and delivery of palliative care research. Design: We convened partners to identify research needs and co-designed activities to meet our objectives. These included a scoping review; a capacity-building programme of training, seminars and a journal club; forming a patient and public involvement group; a multistranded community engagement programme using different creative approaches; four focus groups with members of the public and one with community workers; and producing three 'storytelling' audio recordings. Findings were presented to the partnership at a regional workshop. Results: The scoping review showed that community-engaged palliative care interventions can improve outcomes for individuals but provided little evidence about which approaches work for different communities. Five online seminars and a quarterly journal club to develop research capacity were regularly attended by 15 to 25 participants from across the partnership. While evaluating our engagement methods was beyond the partnership's scope, levels of participation suggested that creative methods of engagement show potential to help researchers and practitioners better understand the needs and priorities of underserved populations. Data showed that rural, coastal and low-income communities face challenges in accessing end-of-life care and support due to issues such as transport to and distance from services, erosion of neighbourhood networks, isolation from family and friends, 'patchiness' of palliative care services and a lack of care providers. Community organisations are well-placed to co-produce and facilitate methodologies for involving communities in palliative care research. Limitations: Although activities took place in diverse areas, it was not possible within the available resources to cover the entire large geographical region, particularly the most isolated rural areas. Conclusions: Partnerships bringing together voluntary and community sector organisations, palliative care providers, health and social care providers, individuals with experience and academics have potential to design future research and public health interventions that better understand local context, involving and supporting communities to address their needs at end of life. Funding: This article presents independent research funded by the National Institute for Health and Care Research (NIHR) Public Health Research programme as award number NIHR135312.

England's South West Peninsula (Cornwall, Devon, Somerset) has high levels of poverty and an ageing population. There are some community groups which enable individuals to support each other at the end of life. However there has been little local palliative (i.e. end-of-life) care research to understand people's needs in rural and coastal areas. We created the South West Peninsula Palliative Care Research Partnership including four universities, voluntary and community organisations (including hospices), health research agencies, and a group of individuals interested in palliative care. We wanted to build a sustainable partnership that would identify what communities need to support each other at end of life and help individuals and organisations to plan and participate in research. We reviewed existing research evidence and ran a programme of training events and community activities (an interactive display, focus groups, one-to-one conversations and 'storytelling'). Finally, we came together to discuss the findings and plan next steps. Getting support at the end of life can be difficult in the region because of poor transport, distance from services, isolation from support networks, and patchy palliative and social care services. We found that using creative ways to involve people, like the interactive display, helped clinicians and researchers better understand local needs. Our experience of partnership working showed that palliative care organisations, academics and community organisations working alongside each other can help services reach these areas, and make it easier for people to be involved in research. We hope that continuing this partnership will help communities share and develop expertise in supporting patients and families with palliative care needs, and help clinical services and universities involve people in rural, coastal and low-income areas in planning, delivering and participating in research that addresses their priorities.

Systematic review and meta-analysis of the association between childhood overweight and obesity and primary school diet and physical activity policies.

Obesity is a major public health concern and there are increasing calls for policy intervention. As obesity and the related health conditions develop during childhood, schools are being seen as important locations for obesity prevention, including multifaceted interventions incorporating policy elements. The objective of this systematic review was to evaluate the effects of policies related to diet and physical activity in schools, either alone, or as part of an intervention programme on the weight status of children aged 4 to 11 years. A comprehensive and systematic search of medical, education, exercise science, and social science databases identified 21 studies which met the inclusion criteria. There were no date, location or language restrictions. The identified studies evaluated a range of either, or both, diet and physical activity related policies, or intervention programmes including such policies, using a variety of observational and experimental designs. The policies were clustered into those which sought to affect diet, those which sought to affect physical activity and those which sought to affect both diet and physical activity to undertake random effects meta-analysis. Within the diet cluster, studies of the United States of America National School Lunch and School Breakfast Programs were analysed separately; however there was significant heterogeneity in the pooled results. The pooled effects of the physical activity, and other diet related policies on BMI-SDS were non-significant. The multifaceted interventions tended to include policy elements related to both diet and physical activity (combined cluster), and although these interventions were too varied to pool their results, significant reductions in weight-related outcomes were demonstrated. The evidence from this review suggests that, when implemented alone, school diet and physical activity related policies appear insufficient to prevent or treat overweight or obesity in children, however, they do appear to have an effect when developed and implemented as part of a more extensive intervention programme. Additional evidence is required before recommendations regarding the focus of policies can be made and therefore, increased effort should be made to evaluate the effect of policies and policy containing intervention programmes upon weight status.
