How can asset-based approaches reduce inequalities? Exploring processes of change in England and Spain.

Initiatives to promote health and reduce inequalities in place-based communities have increasingly adopted asset-based approaches (ABAs). However, the processes through which such initiatives might reduce inequalities are not well understood, and evidence of their impact on health is still limited. This study aimed to understand how ABAs can impact practices, relationships and the redistribution of resources to reduce health inequalities in and between less advantaged neighbourhoods. Qualitative research was conducted in two settings (England and Spain) where similar asset-based initiatives, aimed at training community members to become health promoters, were being implemented. Data were collected using theory of change workshops, 120 hours of observations and semi-structured interviews with 44 stakeholders (trained community members, voluntary and community sector organizations' workers and health professionals). A thematic analysis informed by systems thinking was carried out. Three main processes of change were identified: first, 'enabling asset-based thinking' defined as supporting people to adopt a view that values their own resources and people's skills and expertise. Second, 'developing asset-based capacities', described as developing personal skills, knowledge, self-confidence and relationships underpinned by asset-based thinking. Finally, 'changing decision-making and wider health determinants through ABAs' referred to achieving changes in neighbourhoods through mobilizing the asset-based capacities developed. These processes were associated with changes at an individual level, with potential to contribute to reducing inequalities through supporting individual empowerment and social capital. However, contextual factors were found key to enable or hinder changes in the neighbourhoods and acted as barriers to processes of collective empowerment, thus limiting ABAs' impact on health inequalities.

Trajectories of Child Cognitive and Socioemotional Development and Associations with Adolescent Health in the UK Millennium Cohort Study.

OBJECTIVE: To identify and describe distinct trajectories of cognitive and socioemotional development during childhood and to examine their relationships with adolescent health. STUDY DESIGN: We used group-based multitrajectory modeling applied to longitudinal data on 11 564 children up to age 14 years from the UK Millennium Cohort study to identify trajectories of cognitive and socioemotional development measured using validated instruments. We assessed associations between the derived trajectories and baseline socioeconomic, parental, and school factors using multinomial regression. Logistic regression was used to assess associations between trajectory groups and adolescent health at age 14 and 17 years. RESULTS: Four child development trajectories were identified: "no problems" (76.5%); "late socio-emotional problems" (10.1%); "early cognitive and socioemotional problems" (8.6%); and "persistent cognitive and socioemotional problems" (4.8%). Those in the problem trajectories were more socioeconomically disadvantaged. Compared with the "no problem" trajectory, the "late socioemotional problems" trajectory had increased odds of overweight and mental ill-health at age 14 years of 1.50 (95% CI 1.24-1.81) and 2.51 (2.03-3.10), respectively. For the "persistent problems" group, the OR for overweight was 1.41 (1.04-1.91), and for mental ill-health, 3.01 (2.10-3.30). For both groups, the associations persisted to age 17 years. CONCLUSIONS: In a representative UK cohort, groups of distinct trajectories of cognitive and socioemotional development were identified. Adverse development, if unresolved, can have a negative impact on weight and mental health in adolescence. Socioemotional development was the main driver of the impact on adolescent health and this requires emphasis in child health policy.

Scaling up the "24/7 BHU" strategy to provide round-the-clock maternity care in Punjab, Pakistan: a theory-driven, coproduced implementation study.

BACKGROUND: Pakistan's maternal mortality rate remains persistently high at 186/100,000 live births. The country's government-run first-level healthcare facilities, the basic health units (BHUs), are an important source of maternity care for rural women. However,BHUsonly operate on working days from 8:00 am to 2:00 pm. Recognizing that this severely constrains access to maternity services, the government is implementing the "24/7 BHU" initiative to upgrade BHUs to provide round-the-clock care. Although based on a successful pilot project, initial reports reveal challenges in scaling up the initiative. This implementation research project aims to address a key concern of the Government of Punjab: How can the 24/7 BHU initiative be successfully implemented at scale to provide high-quality, round-the-clock skilled maternity care in rural Punjab? METHODS: The project consists of two overlapping work packages (WP). WP1 includes three modules generating data at the directorate, district and BHU levels. Module 1 uses document analysis and policy-maker interviews to explicateprogrammetheory and begin to build a system model. Module 2 compares government-collected data with data generated from a survey of 1500 births to assess BHU performance. Module 3 uses institutional ethnographies in 4-5 BHUs in three districts to provide a detailed system for understanding and identifying processes that influence scale-up. WP2 includes two modules. First, two workshops and regular meetings with stakeholders integrate WP1 findings, identify feasible changes and establish priorities. Next, "change ideas" are selected for testing in one district and 2-3 BHUs through carefully documented pilots using the PDSA (plan-do-study-act) improvement approach. An integrated knowledge translation approach will engage key policy and practice stakeholders throughout the project. DISCUSSION: This theory-driven implementation research project willcoproducesignificant new understandings of the wider system in which the 24/7 BHU initiative is being implemented, and actionable knowledge that will highlight ways the implementation processes might be modified to enable BHUs to meet service provision goals. This study will also produce insights that will be relevant for other South Asian and low- and middle-income countries (LMICs) that experience similar challenges of programme scale-up and delivery of maternal health services to remote and marginalized communities.

Power, control, communities and health inequalities III: participatory spaces-an English case.

This article-third in a series of three-uses theoretical frameworks described in Part 1, and empirical markers reported in Part 2, to present evidence on how power dynamics shifted during the early years of a major English community empowerment initiative. We demonstrate how the capabilities disadvantaged communities require to exercise collective control over decisions/actions impacting on their lives and health (conceptualized as emancipatory power) and the exercise of power over these communities (conceptualized as limiting power) were shaped by the characteristics of participatory spaces created by and/or associated with this initiative. Two main types of participatory spaces were identified: governance and sense-making. Though all forms of emancipatory power emerged in all spaces, some were more evident in particular spaces. In governance spaces, the development and enactment of 'power to' emerged as residents made formal decisions on action, allocated resources and managed accountability. Capabilities for alliance building-power with-were more likely to emerge in these spaces, as was residents' resistance to the exercise of institutional power over them. In contrast, in sense-making spaces residents met informally and 'made sense' of local issues and their ability to influence these. These processes led to the development of power within capabilities and power to resist stigmatizing forms of productive power. The findings highlight the importance of designing community initiatives that: nurture diverse participatory spaces; attend to connectivity between spaces; and identify and act on existing power dynamics undermining capabilities for collective control in disadvantaged communities.

Power, control, communities and health inequalities. Part II: measuring shifts in power.

In the health field, there is great interest in the role empowerment might play in reducing social inequalities in health. Empowerment is understood here as the processes of developing capabilities that individuals and/or communities need to exercise control over decisions and actions impacting on their lives and health. There is a fundamental problem, however, in identifying and measuring capabilities for collective control that emerge at the level of the collective, with much of the existing literature focusing on individual measures even where community-level processes are concerned. Collective measures need to capture the dynamics of interactions within and between groups, not simply aggregate individual-level measures. This article, Part 2 in a three-part series, takes up the challenge of identifying qualitative markers of capabilities for collective control. We applied the emancipatory power framework (EPF) reported in Part 1 of the series, to qualitative data generated during a longitudinal evaluation of a major English area-based empowerment initiative, the Big Local (BL). We identified empirical 'markers' of shifts towards greater collective control pertaining to each of the 'power' dimensions in the EPF-'power within', 'power with' and 'power to'-and markers of communities exercising 'power over' other institutions/community members. These markers can usefully be applied in the evaluation planning and evaluation of empowerment initiatives. Part 3 in the series uses these markers and a second analytical framework developed during our evaluation of BL to explore how power dynamics unfold in participatory spaces in BL neighbourhoods.

Learning across the UK: a review of public health systems and policy approaches to early child development since political devolution.

BACKGROUND: Giving children the best start in life is critical for their future health and wellbeing. Political devolution in the UK provides a natural experiment to explore how public health systems contribute to children's early developmental outcomes across four countries. METHOD: A systematic literature review and input from a stakeholder group was used to develop a public health systems framework. This framework then informed analysis of public health policy approaches to early child development. RESULTS: A total of 118 studies met the inclusion criteria. All national policies championed a 'prevention approach' to early child development. Political factors shaped divergence, with variation in national conceptualizations of child development ('preparing for life' versus 'preparing for school') and pre-school provision ('universal entitlement' or 'earned benefit'). Poverty and resourcing were identified as key system factors that influenced outcomes. Scotland and Wales have enacted distinctive legislation focusing on wider determinants. However, this is limited by the extent of devolved powers. CONCLUSION: The systems framework clarifies policy complexity relating to early child development. The divergence of child development policies in the four countries and, particularly, the explicit recognition in Scottish and Welsh policy of wider determinants, creates scope for this topic to be a tracer area to compare UK public health systems longer term.

Implementation of healthy food environment policies to prevent nutrition-related non-communicable diseases in Ghana: National experts' assessment of government action.

Nutrition-related non-communicable diseases (NR-NCDs) are a global health problem, increasingly recognised as driven by unhealthy food environments. Yet little is known about government action to implement food environment-relevant policies, particularly in low-and lower-middle income countries. This study assessed government action, implementation gaps, and priorities to improve the food environment in Ghana. Using the Healthy Food-Environment Policy Index (Food-EPI), a panel comprising government and independent experts (n = 19) rated government action to improve the healthiness of food environment in Ghana against international best practices and according to steps within a policy cycle. Forty-three good practice indicators of food environment policy and infrastructure support were used, with ratings informed by systematically collected evidence of action validated by government officials. Following the rating exercise, the expert panel proposed and prioritized actions for government implementation. Three-quarters of all good practice indicators were rated at 'low'/'very little' implementation. Restricting the marketing of breast milk substitutes was the only indicator rated "very high". Of ten policy actions prioritized for implementation, restricting unhealthy food marketing in children's settings and in the media were ranked the highest priority. Providing sufficient funds for nationally-relevant research on nutrition and NCDs was the highest priority infrastructure-support action. Other priority infrastructure-support actions related to leadership, monitoring and evaluation. This study identified gaps in Ghana's implementation of internationally-recommended policies to promote healthy food environments. National stakeholders recommended actions, which will require legislation and leadership. The findings provide a baseline for measuring government progress towards implementing effective policies to prevent NR-NCDs.

Longitudinal impact of the Cyber Friendly Schools program on adolescents' cyberbullying behavior.

Cyberbullying is a major public health problem associated with serious mental, social, and academic consequences for young people. To date, few programs addressing cyberbullying have been developed and empirically tested. The Cyber Friendly Schools (CFS) group-randomized controlled trial measured the longitudinal impact of a whole-school online cyberbullying prevention and intervention program, developed in partnership with young people. Non-government secondary schools in Perth, Western Australia, (N = 35; 3,000+ students) were randomized to an intervention (n = 19) or usual practice control group (n = 16 schools). Students completed online questionnaires in 2010, 2011, and at 1-year follow-up in 2012, measuring their cyberbullying experiences during the previous school term. The intervention group received the program in Grades 8 and 9 (aged 13-14 years). Program effects were tested using two-part growth models. The program was associated with significantly greater declines in the odds of involvement in cyber-victimization and perpetration from pre- to the first post-test, but no other differences were evident between the study conditions. However, teachers implemented only one third of the program content. More work is needed to build teacher capacity and self-efficacy to effectively implement cyberbullying programs. Whole-school cyberbullying interventions implemented in conjunction with other bullying prevention programs may reduce cyber-victimization more than traditional school-based bullying prevention programs alone.

Activated macrophages promote hepatitis C virus entry in a tumor necrosis factor-dependent manner.

UNLABELLED: Macrophages are critical components of the innate immune response in the liver. Chronic hepatitis C is associated with immune infiltration and the infected liver shows a significant increase in total macrophage numbers; however, their role in the viral life cycle is poorly understood. Activation of blood-derived and intrahepatic macrophages with a panel of Toll-like receptor agonists induce soluble mediators that promote hepatitis C virus (HCV) entry into polarized hepatoma cells. We identified tumor necrosis factor α (TNF-α) as the major cytokine involved in this process. Importantly, this effect was not limited to HCV; TNF-α increased the permissivity of hepatoma cells to infection by Lassa, measles and vesicular stomatitis pseudoviruses. TNF-α induced a relocalization of tight junction protein occludin and increased the lateral diffusion speed of HCV receptor tetraspanin CD81 in polarized HepG2 cells, providing a mechanism for their increased permissivity to support HCV entry. High concentrations of HCV particles could stimulate macrophages to express TNF-α, providing a direct mechanism for the virus to promote infection. CONCLUSION: This study shows a new role for TNF-α to increase virus entry and highlights the potential for HCV to exploit existing innate immune responses in the liver to promote de novo infection events.

IFITM1 is a tight junction protein that inhibits hepatitis C virus entry.

UNLABELLED: Type 1 interferon (IFN) continues to be the foundation for the current standard of care combination therapy for chronic hepatitis C virus (HCV) infection, yet the component interferon-stimulated genes (ISGs) that mediate the antiviral actions of IFN are not fully defined. Interferon-induced transmembrane protein 1 (IFITM1) is an ISG product that suppresses early stage infection by a number of viruses through an unknown mechanism of action. Moreover, the actions of IFITM1 on HCV infection are not fully elucidated. Here we identify IFITM1 as a hepatocyte tight junction protein and a potent anti-HCV effector molecule. IFITM1 expression is induced early during IFN treatment of hepatocytes and accumulates at hepatic tight junctions in HCV-infected human patient liver during IFN therapy. Additionally, we found that IFITM1 interacts with HCV coreceptors, including CD81 and occludin, to disrupt the process of viral entry. Thus, IFITM1 is an anti-HCV ISG whose actions impart control of HCV infection through interruption of viral coreceptor function. CONCLUSION: This study defines IFITM1 as an ISG effector with action against HCV entry. Design of therapy regimens to enhance IFITM1 expression should improve the virologic response among HCV patients undergoing treatment with type I IFN.

Elevating leadership learning: Critical considerations for training, design, and implementation.

This article focuses on the research and scholarship of leadership training. We begin by defining and giving context to the concept of leadership training. Then, we provide a high-level literature review of the history and components of leadership training (e.g., content, pedagogy, and assessment). Next, we connect leadership training with the leadership learning framework (LLF) to address common critiques of leadership training. The article concludes with projections of leadership training in the future and ethical questions for leadership educators to consider when designing leadership training programs.

Short communication: Five ways UK European Capitals and cities of culture have connected cultural activities with nature and their impacts on health and wellbeing, wider determinants of health and inequality.

Objective: To rapidly synthesise evidence for local practice on what initiatives UK European Capitals and Cities of Culture (UKEUCoCs) have implemented connecting cultural activities with green, blue, or outdoor space (culture-nature initiatives) and their impacts on planetary health outcomes: personal health and wellbeing, wider determinants of health particularly the environment, and existing inequality. Study design: Rapid evidence review. Methods: A rapid review of published articles and evaluation reports. Published articles were identified through database searches (Proquest, OVID, Scopus, Web of Science, MEDLINE) in January-February 2024. Data was extracted directly into a table and findings synthesised narratively by theme. Results: Published evidence about UKEUCoC culture-nature initiatives was limited but five initiative types were identified: 1) growing-focused activities; 2) activities exploring human-nature relationships; 3) targeted nature-based wellbeing activities; 4) activities connecting cultural engagement with environmental activism; and 5) use of outdoor spaces for artworks, performances and festivals. UKEUCoC culture-nature initiatives may contribute to short-term improvements in mental health and wellbeing (confidence, self-esteem, subjective wellbeing), community health (community relations, civic pride), cultural participation, and local environmental quality and use, but risk widening existing inequalities. Co-creating initiatives at hyper-local levels with marginalised groups and trusted Community Champions, active involvement, and creating equitable access to livelihood opportunities may mitigate inequality risks. Conclusions: Evidence is limited but suggests UKEUCoC culture-nature initiatives could positively support planetary health outcomes in the short-term. Equity in these outcomes appears to rely however, on action to ensure the involvement of and sustainable livelihood creation for marginalised groups. It is unclear how outcomes are generated across the initiative types identified, including through interactions between them, where they are implemented. The five initiative types identified in this work could be targeted for further investigation in research and practice on culture-nature initiatives for health more generally, using a complex systems approach to evaluation.

Exploring the motivations of female community health volunteers in primary healthcare provision in rural Nepal: A qualitative study.

Motivating Community Health Workers (CHWs)-many of whom are volunteers-is crucial for achieving Universal Healthcare Coverage (UHC) for Primary Healthcare (PHC) in resource-poor areas. In rural Nepal, PHC is mostly delivered by female CHWs, locally known as Female Community Health Volunteers (FCHVs), but little is known about them. This paper explores experiential factors influencing FCHVs' motivations, including how motivation intersects with women's livelihoods and consider what this means for achieving PHC in Nepal and globally. We conducted qualitative research in the hill and the Terai (flatland bordering India) areas of Nepal. Data were purposively collected through 31 semi-structured interviews (20 volunteers, 11 paid local health workers) and three focus group discussions with additional 15 volunteers. All interviews were audio-recorded, transcribed verbatim in Nepali and translated into English. Data were coded using NVivo10, analysed thematically at individual, organisational and community levels. FCHVs' motivations to volunteer was affected in several ways. At the individual level, participants wanted and were committed to voluntary work, yet the opportunity costs of volunteering, out-of-pocket expenditure and inadequate family support strained many of the women who were already overburdened. At the community level, perceived lack of appreciation of volunteer efforts by community members, who saw volunteers as paid health workers, undermined FCHVs motivation to volunteer. Finally, at the organizational level, a bureaucratic emphasis on recording and reporting, and lack of respect from local health workers undermined their motivation at work. Our paper illustrates how FCHVs from some of the poorest backgrounds can be highly motivated to volunteer, yet inadequate social and economic support across individual, organisational and community levels undermined this motivation, the security of their livelihoods, and thus wider efforts to achieve PHC. Financial investments are needed to compensate FCHVs, so that they remain motivated to deliver global health goals for PHC.

Comparison of the Impact of Conventional and Web-Based Pulmonary Rehabilitation on Physical Activity in Patients With Chronic Obstructive Pulmonary Disease: Exploratory Feasibility Study.

BACKGROUND: Pulmonary Rehabilitation (PR) increases exercise capacity, with less clear evidence regarding physical activity (PA). The World Health Organization recommends at least 150-300 minutes of moderate-intensity or 75-150 minutes of vigorous-intensity aerobic PA per week to reduce the risks of chronic disease. OBJECTIVE: The objective of this study was to assess the effectiveness of conventional PR versus web-based PR with respect to changes in PA. METHODS: Patients with COPD were randomized to either conventional PR classes (n=51) or a web-based PR program (n=52) for 7 weeks in a feasibility study. Accelerometers (Sensewear) were worn before and after the intervention, and PA was measured as steps per day and mean bouts of moderate activity for ≥2, ≥5, ≥10, and ≥20 minutes. Measures were derived for patients with ≥8 hours of data per day for ≥4 days, using the R package for statistical analysis. Variables were explored to examine their relationships with bouts of activity. RESULTS: Baseline characteristics did not differ significantly between groups. Complete PA data were available for the groups receiving web-based (n=20) and conventional (n=34) PR interventions. The web-based PR group demonstrated a nonsignificant increase in the number of steps per day, which mainly comprised short bouts of moderate to vigorous intensity PA when compared to the conventional PR group (P=.20). The conventional PR group demonstrated increased 20-minute bouts of PA by 49.1%, although this was not significant (P=.07). At baseline, age (r=-0.21, P=.04), BMI (r=-0.311, P=.004), and FEV1 (forced expiratory volume in 1 second; % predicted; r=-0.248, P=.048) were significantly correlated with 10-minute bouts of PA; however, this was not observed post intervention. CONCLUSIONS: The analysis revealed a nonsignificant difference in the pattern of PA between groups receiving conventional vs web-based PR-the former being associated with an increase in 20-minute bouts, while the latter having demonstrated an increase in the number of steps per day. There appears to be a differing response emerging between the two interventions. TRIAL REGISTRATION: International Clinical Trials Registry ISRCTN03142263; https://tinyurl.com/y4dmfyrb.

Accurate species identification of food-contaminating beetles with quality-improved elytral images and deep learning.

Food samples are routinely screened for food-contaminating beetles (i.e., pantry beetles) due to their adverse impact on the economy, environment, public health and safety. If found, their remains are subsequently analyzed to identify the species responsible for the contamination; each species poses different levels of risk, requiring different regulatory and management steps. At present, this identification is done through manual microscopic examination since each species of beetle has a unique pattern on its elytra (hardened forewing). Our study sought to automate the pattern recognition process through machine learning. Such automation will enable more efficient identification of pantry beetle species and could potentially be scaled up and implemented across various analysis centers in a consistent manner. In our earlier studies, we demonstrated that automated species identification of pantry beetles is feasible through elytral pattern recognition. Due to poor image quality, however, we failed to achieve prediction accuracies of more than 80%. Subsequently, we modified the traditional imaging technique, allowing us to acquire high-quality elytral images. In this study, we explored whether high-quality elytral images can truly achieve near-perfect prediction accuracies for 27 different species of pantry beetles. To test this hypothesis, we developed a convolutional neural network (CNN) model and compared performance between two different image sets for various pantry beetles. Our study indicates improved image quality indeed leads to better prediction accuracy; however, it was not the only requirement for achieving good accuracy. Also required are many high-quality images, especially for species with a high number of variations in their elytral patterns. The current study provided a direction toward achieving our ultimate goal of automated species identification through elytral pattern recognition.

Can leadership assessments do harm? Considerations for the ethical use of assessments in leadership development.

This article explores the ethical use of assessments in leadership training, education, and development. From the importance of having well-trained facilitators to the consideration of power and social identity in the interpretation of individual results, this article advocates for approaching the use of leadership assessments and inventories with a critical ethic of care. This practical focus on ethics serves as a compliment to the other articles in this text by helping leadership educators and leadership professionals apply this critical lens to every facilitation.

Impact of child development at primary school entry on adolescent health-protocol for a participatory systematic review.

BACKGROUND: Reducing child health inequalities is a global health priority and evidence suggests that optimal development of knowledge, skills and attributes in early childhood could reduce health risks across the life course. Despite a strong policy rhetoric on giving children the 'best start in life', socioeconomic inequalities in children's development when they start school persist. So too do inequalities in child and adolescent health. These in turn influence health inequalities in adulthood. Understanding how developmental processes affect health in the context of socioeconomic factors as children age could inform a holistic policy approach to health and development from childhood through to adolescence. However, the relationship between child development and early adolescent health consequences is poorly understood. Therefore the aim of this review is to summarise evidence on the associations between child development at primary school starting age (3-7 years) and subsequent health in adolescence (8-15 years) and the factors that mediate or moderate this relationship. METHOD: A participatory systematic review method will be used. The search strategy will include; searches of electronic databases (MEDLINE, PsycINFO, ASSIA and ERIC) from November 1990 onwards, grey literature, reference searches and discussions with stakeholders. Articles will be screened using inclusion and exclusion criteria at title and abstract level, and at full article level. Observational, intervention and review studies reporting a measure of child development at the age of starting school and health outcomes in early adolescence, from a member country of the Organisation for Economic Co-operation and Development, will be included. The primary outcome will be health and wellbeing outcomes (such as weight, mental health, socio-emotional behaviour, dietary habits). Secondary outcomes will include educational outcomes. Studies will be assessed for quality using appropriate tools. A conceptual model, produced with stakeholders at the outset of the study, will act as a framework for extracting and analysing evidence. The model will be refined through analysis of the included literature. Narrative synthesis will be used to generate findings and produce a diagram of the relationship between child development and adolescent health. DISCUSSION: The review will elucidate how children's development at the age of starting school is related to subsequent health outcomes in contexts of socioeconomic inequality. This will inform ways to intervene to improve health and reduce health inequality in adolescents. The findings will generate knowledge of cross-sector relevance for health and education and promote inter-sectoral coherence in addressing health inequalities throughout childhood. PROTOCOL REGISTRATION: This systematic review protocol has been registered with PROSPERO CRD42020210011 .

Optimized imaging methods for species-level identification of food-contaminating beetles.

Identifying the exact species of pantry beetle responsible for food contamination, is imperative in assessing the risks associated with contamination scenarios. Each beetle species is known to have unique patterns on their hardened forewings (known as elytra) through which they can be identified. Currently, this is done through manual microanalysis of the insect or their fragments in contaminated food samples. We envision that the use of automated pattern analysis would expedite and scale up the identification process. However, such automation would require images to be captured in a consistent manner, thereby enabling the creation of large repositories of high-quality images. Presently, there is no standard imaging technique for capturing images of beetle elytra, which consequently means, there is no standard method of beetle species identification through elytral pattern analysis. This deficiency inspired us to optimize and standardize imaging methods, especially for food-contaminating beetles. For this endeavor, we chose multiple species of beetles belonging to different families or genera that have near-identical elytral patterns, and thus are difficult to identify correctly at the species level. Our optimized imaging method provides enhanced images such that the elytral patterns between individual species could easily be distinguished from each other, through visual observation. We believe such standardization is critical in developing automated species identification of pantry beetles and/or other insects. This eventually may lead to improved taxonomical classification, allowing for better management of food contamination and ecological conservation.

Relationships between Child Development at School Entry and Adolescent Health-A Participatory Systematic Review.

The relationship between child development and adolescent health, and how this may be modified by socio-economic conditions, is poorly understood. This limits cross-sector interventions to address adolescent health inequality. This review summarises evidence on the associations between child development at school starting age and subsequent health in adolescence and identifies factors affecting associations. We undertook a participatory systematic review, searching electronic databases (MEDLINE, PsycINFO, ASSIA and ERIC) for articles published between November 1990 and November 2020. Observational, intervention and review studies reporting a measure of child development and subsequent health outcomes, specifically weight and mental health, were included. Studies were individually and collectively assessed for quality using a comparative rating system of stronger, weaker, inconsistent or limited evidence. Associations between child development and adolescent health outcomes were assessed and reported by four domains of child development (socio-emotional, cognitive, language and communication, and physical development). A conceptual diagram, produced with stakeholders at the outset of the study, acted as a framework for narrative synthesis of factors that modify or mediate associations. Thirty-four studies were included. Analysis indicated stronger evidence of associations between measures of socio-emotional development and subsequent mental health and weight outcomes; in particular, positive associations between early externalising behaviours and later internalising and externalising, and negative associations between emotional wellbeing and later internalising and unhealthy weight. For all other domains of child development, although associations with subsequent health were positive, the evidence was either weaker, inconsistent or limited. There was limited evidence on factors that altered associations. Positive socio-emotional development at school starting age appears particularly important for subsequent mental health and weight in adolescence. More collaborative research across health and education is needed on other domains of development and on the mechanisms that link development and later health, and on how any relationship is modified by socio-economic context.

Policy Action Within Urban African Food Systems to Promote Healthy Food Consumption: A Realist Synthesis in Ghana and Kenya.

BACKGROUND: Obesity and nutrition-related non-communicable diseases (NR-NCDs) are increasing throughout Africa, driven by urbanisation and changing food environments. Policy action has been limited - and influenced by high income countries. Socio-economic/political environments of African food systems must be considered in order to understand what policy might work to prevent NR-NCDs, for whom, and under what circumstances. METHODS: A realist synthesis of five policy areas to support healthier food consumption in urban Africa: regulating trade/foreign investment; regulating health/nutrition claims/labels; setting composition standards for processed foods; restricting unhealthy food marketing; and school food policy. We drew upon Ghana and Kenya to contextualise the evidence base. Programme theories were generated by stakeholders in Ghana/Kenya. A two-stage search interrogated MEDLINE, Web of Science and Scopus. Programme theories were tested and refined to produce a synthesised model. RESULTS: The five policies operate through complex, inter-connected pathways moderated by global-, national- and local contexts. Consumers and the food environment interact to enable/disable food accessibility, affordability and availability. Consumer relationships with each other and retailers are important contextual influences, along with political/ economic interests, stakeholder alliances and globalized trade. Coherent laws/regulatory frameworks and government capacities are fundamental across all policies. The increasing importance of convenience is shaped by demographic and sociocultural drivers. Awareness of healthy diets mediates food consumption through comprehension, education, literacy and beliefs. Contextualised data (especially food composition data) and inter-sectoral collaboration are critical to policy implementation. CONCLUSION: Evidence indicates that coherent action across the five policy areas could positively influence the healthiness of food environments and consumption in urban Africa. However, drivers of (un)healthy food environments and consumption reflect the complex interplay of socio-economic and political drivers acting at diverse geographical levels. Stakeholders at local, national, and global levels have important, yet differing, roles to play in ensuring healthy food environments and consumption in urban Africa.
