Building a systems-thinking community workforce to scale action on determinants of health in New Zealand.

This article describes findings from the evaluation of Healthy Families NZ (HFNZ), an equity-driven, place-based community health initiative. Implemented in nine diverse communities across New Zealand, HFNZ aims to strengthen the systems that can improve health and well-being. Findings highlight local needs and priorities including the social mechanisms important for reorienting health and policy systems towards place-based communities. Lessons encompass the importance of local lived experience in putting evidence into practice; the strength of acting with systems in mind; the need for relational, learning, intentional, and well-resourced community organisation; examples of how to foster place-based 'community-up' leadership; and how to enable responsiveness between communities and local and national policy systems. A reconceptualisation of scaling in the context of complexity and systems change is offered, which recognises that relationships and agency are key to making progress on the determinants of health.

Dietary practices, physical activity and social determinants of non-communicable diseases in Nepal: A systemic analysis.

Unhealthy dietary habits and physical inactivity are major risk factors of non-communicable diseases (NCDs) globally. The objective of this paper was to describe the role of dietary practices and physical activity in the interaction of the social determinants of NCDs in Nepal, a developing economy. The study was a qualitative study design involving two districts in Nepal, whereby data was collected via key informant interviews (n = 63) and focus group discussions (n = 12). Thematic analysis of the qualitative data was performed, and a causal loop diagram was built to illustrate the dynamic interactions of the social determinants of NCDs based on the themes. The study also involved sense-making sessions with policy level and local stakeholders. Four key interacting themes emerged from the study describing current dietary and physical activity practices, influence of junk food, role of health system and socio-economic factors as root causes. While the current dietary and physical activity-related practices within communities were unhealthy, the broader determinants such as socio-economic circumstances and gender further fuelled such practices. The health system has potential to play a more effective role in the prevention of the behavioural and social determinants of NCDs.

Smashing the patriarchy to address gender health inequities: Past, present and future perspectives from Aotearoa (New Zealand).

The second wave feminist dream of smashing the patriarchy remains a task yet to be completed on a complex to do list. Women, particularly able-bodied cis-gendered white women however do enjoy the privilege of living longer than men. But our longer lives take place within patriarchal-capitalist systems where many women's social and cultural rights continue to be compromised. How do we ensure that all women can exercise our right to health and wellbeing? In this paper, the authors examine, critique, review and re-vision the dynamics of power and patriarchy over three distinct time periods - 1999, 2019 and 2039. We look to the past to track progress; we look to the present to see what we have achieved and look to the future for what might be. This conceptual paper is informed by the authors' expert knowledge, a review of the literature and the novel use of speculative ethnography. The authors conclude that patriarchy remains not only a negative determinant of women's health that needs to be smashed, but is also a threat to all people and to planetary health.

Individual and community experience of rising burden of non-communicable diseases in two case districts of Nepal: a qualitative exploration.

INTRODUCTION: Non-communicable diseases (NCDs) are a rapidly emerging global health challenge with multi-level determinants popularly known as social determinants. The objective of this paper is to describe the individual and community experiences of NCDs in the two case districts of Nepal from a social determinants of health perspective. METHOD: This study adopted qualitative study design to identify the experiences of NCDs. Sixty-three interviews were conducted with key informants from different sectors pertinent to NCD prevention at two case districts and at the policy level in Nepal. Twelve focus group discussions were conducted in the selected communities within those case districts. Data collection and analysis were informed by the adapted Social Determinants of Health Framework. The research team utilised the framework approach to carry out the thematic analysis. The study also involved three sense-making workshops with policy level and local stakeholders. RESULTS: Three key themes emerged during the analysis. The first theme highlighted that individuals and communities were experiencing the rising burden of NCDs and metabolic risks in both urban and rural areas. The other two themes elaborated on the participant's experiences based on their socio-economic background and gender. Disadvantaged populations were more vulnerable to the risk of NCDs. Further, being female put one into an even more disadvantaged position in experiencing NCD risks and accessing health services. CONCLUSION: The findings indicated that key social determinants such as age, geographical location, socio-economic status and gender were driving the NCD epidemic. There is an urgent need to take action on social determinants of health through multi-sectoral action, thus also translating the spirit of the recommendations made a decade ago by the Commission on Social Determinants of Health in addressing a complex challenge like NCDs in Nepal.

Assessing youth empowerment and co-design to advance Pasifika health: a qualitative research study in New Zealand.

OBJECTIVES: The Pasifika Prediabetes Youth Empowerment Programme (PPYEP) was a community-based research project that aimed to investigate empowerment and co-design modules to build the capacity of Pasifika youth to develop community interventions for preventing prediabetes. METHODS: This paper reports findings from a formative evaluation process of the programme using thematic analysis. It emphasises the adoption, perceptions and application of empowerment and co-design based on the youth and community providers' experiences. RESULTS: We found that the programme fostered a safe space, increased youth's knowledge about health and healthy lifestyles, developed their leadership and social change capacities, and provided a tool to develop and refine culturally centred prediabetes-prevention programmes. These themes emerged non-linearly and synergistically throughout the programme. CONCLUSIONS: Our research emphasises that empowerment and co-design are complementary in building youth capacity in community-based partnerships in health promotion. Implications for public health: Empowerment and co-design are effective tools to develop and implement culturally tailored health promotion programmes for Pasifika peoples. Future research is needed to explore the programme within different Pasifika contexts, health issues and Indigenous groups.

Women, Patriarchy and Health Inequalities: The Urgent Need to Reorient Our Systems.

This Special Issue is entitled "Women, patriarchy, and health inequalities: an unresolved issue" [...].

Pasifika Prediabetes Youth Empowerment Programme: learnings from a youth-led community-based intervention study.

AIM: Using a co-design approach, we describe exploratory findings of a community-based intervention to mobilise Pasifika communities into action, with the intent of reducing the risk factors of prediabetes. METHOD: A group of 25 Pasifika youth aged 15-24 years from two distinctive Pasifika communities in New Zealand were trained to lead a small-scale, community-based intervention programme (among 29 participants) over the course of eight weeks. The intervention, which targeted adults aged 25-44 years who were overweight or obese, employed both an empowerment-based programme and a co-design approach to motivate community members to participate in a physical-activity-based intervention programme. RESULTS: Findings show significant reductions in total body weight and waist circumference, as well as improved physical activity. CONCLUSIONS: The strength of this intervention was evident in the innovative approach of utilising Pasifika-youth-led and co-designed approaches to motivate communities into healthier lifestyles. The approaches used in this project could be utilised in a primary healthcare setting as a community-wide strategy to reduce diabetes risk, particularly among Pasifika peoples.

Developing principles of social change as a result of a Pasifika Youth Empowerment Program: A qualitative study.

ISSUE: Empowerment is a concept over-used in health promotion, yet it is an important process that can used in developing the capacity and capability of young people for creating social change to improve healthier lives. METHODS: The Youth Empowerment Program (YEP), a pilot study aimed at empowering 15 youth (18-24 years) to lead healthier lives. We present secondary outcomes of the original YEP study, using focus groups and mobile-mentary approaches to capture the impact of the YEP through the youths' understanding of the program. Thematic analyses to examine the pragmatic usefulness of the empowerment program. RESULTS: We identified three major themes: (aa) Knowledge: education and awareness of healthy living and understanding of the wider social health issues, compound the health complexities of obesity; (b) Youth as catalysts for change: the youth viewed themselves as agents of social change; and (c) Transformation: the youth recognised themselves as catalysts for change that can positively transform communities into action. CONCLUSION: This study contributes new insights and depth of understanding about how the empowerment program can strengthen the process of individual capacity in an effort to mobilise social change for the betterment of the whole community, particularly among indigenous Pasifika population groups. SO WHAT?: Developing empowerment principles will enable others to consider "how apply" empowerment more practically when working with young people and not use it flippantly with no real action-oriented outcome.

The role of tobacco and alcohol use in the interaction of social determinants of non-communicable diseases in Nepal: a systems perspective.

BACKGROUND: Tobacco and alcohol use are major behavioural risks in developing countries like Nepal, which are contributing to a rapid increase in non-communicable diseases (NCDs). This causal relationship is further complicated by the multi-level social determinants such as socio-political context, socio-economic factors and health systems. The systems approach has potential to facilitate understanding of such complex causal mechanisms. The objective of this paper is to describe the role of tobacco and alcohol use in the interaction of social determinants of NCDs in Nepal. METHOD: The study adopted a qualitative study design guided by the Systemic Intervention methodology. The study involved key informant interviews (n = 63) and focus group discussions (n = 12) at different levels (national, district and/or community) and was informed by the adapted Social Determinants of Health Framework. The data analysis involved case study-based thematic analysis using framework approach and development of causal loop diagrams. The study also involved three sense-making sessions with key stakeholders. RESULTS: Three key themes and causal loop diagrams emerged from the data analysis. Widespread availability of tobacco and alcohol products contributed to the use and addiction of tobacco and alcohol. Low focus on primary prevention by health systems and political influence of tobacco and alcohol industries were the major contributors to the problem. Gender and socio-economic status of families/communities were identified as key social determinants of tobacco and alcohol use. CONCLUSION: Tobacco and alcohol use facilitated interaction of the social determinants of NCDs in the context of Nepal. Socio-economic status of families was both driver and outcome of tobacco and alcohol use. Health system actions to prevent NCDs were delayed mainly due to lack of system insights and commercial influence. A multi-sectoral response led by the health system is urgently needed.

Health Inequality as a Large-Scale Outcome of Complex Social Systems: Lessons for Action on the Sustainable Development Goals.

Action on the Sustainable Development Goals (SDGs) needs to become real and impactful, taking a "whole systems" perspective on levers for systems change. This article reviews what we have learned over the past century about the large-scale outcome of health inequality, and what we know about the behaviour of complex social systems. This combined knowledge provides lessons on the nature of inequality and what effective action on our big goals, like the SDGs, might look like. It argues that economic theories and positivist social theories which have dominated the last 150 years have largely excluded the nature of human connections to each other, and the environment. This exclusion of intimacy has legitimatised arguments that only value-free economic processes matter for macro human systems, and only abstract measurement constitutes valuable social science. Theories of complex systems provide an alternative perspective. One where health inequality is viewed as emergent, and causes are systemic and compounding. Action therefore needs to be intensely local, with power relationships key to transformation. This requires conscious and difficult intervention on the intolerable accumulation of resources; improved reciprocity between social groups; and reversal of system flows, which at present ebb away from the local and those already disadvantaged.

Strengthening prevention in communities through systems change: lessons from the evaluation of Healthy Families NZ.

This article presents the findings from the first 3 years of the evaluation of Healthy Families NZ, a systems-change intervention to prevent chronic diseases in 10 communities. The initiative, which builds on existing prevention activities, aims to strengthen the health prevention system through evidence-driven action to enable people to make good food choices, be physically active, smoke-free and free from alcohol-related harm. Key investment areas are a dedicated systems thinking and acting health promotion workforce, and activating leaders who can influence transformational change. The evaluation to date has found the initiative is being implemented with integrity. Evidence indicates a shift towards greater action on prevention, and the prevention system being strengthened. Maori ownership has been enabled, and prioritizing equity has led teams to utilize methods that amplify diverse local perspectives. There is progress on developing a flexible workforce through adaptive learning, flexible resources, professional development and a responsive National team. There is also progress in activating local leadership and empowering local teams. The initiative design has explicitly taken into account the context of complexity within which it is being implemented. It has evolved to focus on action that can accelerate sharing information and practices within communities, and between policy and decision-makers. Healthy Families NZ and its evaluation have been refunded to 2022. This provides an important opportunity to gather further insight into effective ways to strengthen the community agency and trust needed to promote and deliver evidence-based action on prevention.

Non-communicable disease prevention in Nepal: systemic challenges and future directions.

Developing countries such as Nepal are experiencing a double burden of communicable and non-communicable diseases (NCDs) resulting in social and economic losses. In Nepal, more than half of the disease burden is due to NCDs. The major NCDs in Nepal are cardiovascular diseases, cancers, chronic respiratory diseases and diabetes. Behavioural factors such as tobacco use, alcohol consumption, physical inactivity and unhealthy diet are driving the epidemic of NCDs, which are further influenced by social, economic and environmental determinants. The health system of Nepal has not been able to address the ever-increasing burden of NCDs. With the formulation of the Multisectoral Action Plan for Prevention and Control of NCDs 2014-2020, there has been some hope for tackling the NCDs and their social determinants in Nepal through a primary prevention approach. This paper discusses the systemic challenges and recommends two key actions for the prevention and control of NCDs in Nepal.

Evaluating a community-based public health intervention using a complex systems approach.

Background: This article outlines the methods being used to evaluate a community-based public health intervention. This evaluation approach recognizes that not only is the intervention, Healthy Families NZ, complex, but the social systems within which it is being implemented are complex. Methods: To address challenges related to complexity, we discuss three developing areas within evaluation theory and apply them to an evaluation case example. The example, Healthy Families NZ, aims to strengthen the prevention system in Aotearoa/New Zealand to prevent chronic disease in 10 different geographic areas. Central to the evaluation design is the comparative case method which recognizes that emergent outcomes are the result of 'configurations of causes'. 'Thick', mixed-data, case studies are developed, with each case considered a view of a complex system. Qualitative Comparative Analysis is the analytical approach used to systematically compare the cases over time. Conclusions: This article describes an approach to evaluating a community-based public health intervention that considers the social systems in which the initiative is being implemented to be complex. The evaluation case example provides a unique opportunity to operationalize and test these methods, while extending their more frequent use within other fields to the field of public health.

Social determinants of common metabolic risk factors (high blood pressure, high blood sugar, high body mass index and high waist-hip ratio) of major non-communicable diseases in South Asia region: a systematic review protocol.

BACKGROUND: Prevalence of non-communicable diseases has been increasing at a greater pace in developing countries and, in particular, the South Asia region. Various behavioral, social and environmental factors present in this region perpetuate common metabolic risk factors of non-communicable diseases. This study will identify social determinants of common metabolic risk factors of major non-communicable diseases in the context of the South Asian region and map their causal pathway. METHODS: A systematic review of selected articles will be carried out following Cochrane guidelines. Review will be guided by Social Determinants of Health Framework developed by the World Health Organization to extract social determinants of metabolic risk factors of non-communicable diseases from studies. A distinct search strategy will be applied using key words to screen relevant studies from online databases. Primary and grey literature published from the year 2000 to 2016 and studies with discussion on proximal and distal determinants of non-communicable risk factors among adults of the South Asia region will be selected. They will be further checked for quality, and a matrix illustrating contents of selected articles will be developed. Thematic content analysis will be done to trace social determinants and their interaction with metabolic risk factors. Findings will be illustrated in causal loop diagrams with social determinants of risk factors along with their interaction (feedback mechanism). DISCUSSION: The review will describe the interplay of social determinants of common NCD metabolic risk factors in the form of causal loop diagram. Findings will be structured in two parts: the first part will explain the linkage between proximal determinants with the metabolic risk factors and the second part will describe the linkage among the risk factors, proximal determinants and distal determinants. Evidences across different regions will be discussed to compare and validate and/or contrast the findings. Possible bias and limitations of this study will also be discussed. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017067212.

Principles and strategies for improving the prevention of cardio-metabolic diseases in indigenous populations: An international Delphi study.

The disparity in life expectancy between Indigenous and non-Indigenous populations, including within high-income countries, is driven by a heightened risk of cardio-metabolic diseases. The current study recruited independent panels of experts in Indigenous cardio-metabolic health from Australia, New Zealand and the United States, in order to establish local consensus opinion and initiate dialogue on appropriate prevention strategies. Therefore, a three-round Delphi process was used to consolidate and compare the opinions of 60 experts, 20 from each country. Round one, the experts were asked twelve open-ended questions across six domains: (i) prevention; (ii) consultation; (iii) educational resources; (iv) societal issues; (v) workforce issues; (vi) culture and family. Round two, the experts completed a structured questionnaire based on results from the first round, in which they ranked items according to their importance. Final round, the experts were asked to re-rank the same items after receiving summary feedback about the rank ordering from the previous round. Several themes emerged common to all three countries: (i) socio-economic and education inequalities should be addressed; (ii) educational, behaviour change and prevention strategies should address physical environmental determinants and be responsive to the local context, including being culturally appropriate; and (iii) cultural appropriateness can be achieved through consultation with Indigenous communities, cultural competency training, use of Indigenous health workers, and use of appropriate role models. These findings highlight several key priorities that can be used to initiate dialogue on appropriate prevention strategies. Such strategies should be contextualized to the local Indigenous populations.

Efficacy of Exercise Intervention for Weight Loss in Overweight and Obese Adolescents: Meta-Analysis and Implications.

BACKGROUND: The global rise in obesity prevalence among children and adolescents has been linked to modifiable lifestyle factors, including lack of physical activity. However, no known meta-analysis has been conducted on the effects of exercise intervention on body composition and cardiometabolic risk factors in overweight and obese adolescents. OBJECTIVES: The aim of this study was to (1) estimate whether exercise intervention meaningfully improves body composition and cardiometabolic risk factors in overweight and obese adolescents; and (2) discuss the implications of the findings in terms of primary healthcare provision and public health policy, using New Zealand as an exemplar context. DATA SOURCES: Electronic databases (PubMed, Web of Science, SPORTDiscus, Google Scholar) from inception to May 2015. The reference lists of eligible articles and relevant reviews were also checked. STUDY SELECTION: Inclusion criteria were (1) randomized controlled trial; (2) structured exercise intervention, alone or combined with any other kind of intervention; (3) control group received no structured exercise or behavioural modification designed to increase physical activity; (4) participants overweight or obese (body mass index [BMI] ≥85th percentile); and (5) participants aged between 10 and 19 years. APPRAISAL AND SYNTHESIS METHODS: Initially, 1667 articles were identified. After evaluation of study characteristics, quality and validity, data from 13 articles (15 trials) involving 556 participants (176 male, 193 female, 187 unknown) were extracted for meta-analysis. Meta-analyses were completed on five body composition parameters and ten cardiometabolic parameters. Effect sizes (ESs) were calculated as mean differences, as well as standardized mean differences in order to determine effect magnitude. RESULTS: Exercise intervention reduced BMI (mean 2.0 kg/m2, 95 % CI 1.5-2.5; ES moderate), body weight (mean 3.7 kg, 95 % CI 1.7-5.8; ES small), body fat percentage (3.1 %, 95 % CI 2.2-4.1; ES small), waist circumference (3.0 cm, 95 % CI 1.3-4.8; ES small), but the increase (improvement) in lean mass was trivial (mean 1.6 kg, 95 % CI 0.5-2.6). The response to an oral glucose tolerance test following exercise intervention was for a decrease in the area under the curve for insulin (mean 162 µU/µl, 95 % CI 93-231; ES large) and blood glucose (mean 39 mg/dl, 95 % CI 9.4-69; ES moderate). Improvements in the homeostatic model assessment were also noted (mean 1.0, 95 % CI 0.7-1.4; ES moderate) and systolic blood pressure (mean 7.1 mmHg, 95 % CI 3.5-10.7; ES moderate). The effects of exercise on total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting insulin and fasting blood glucose were inconclusive. LIMITATIONS: Most of the included trials were short term (6-36 weeks) and 13 had methodological limitations. Additionally, the meta-analyses for some of the secondary outcomes had a small number of participants or substantial statistical heterogeneity. CONCLUSIONS: The current evidence suggests that exercise intervention in overweight and obese adolescents improves body composition, particularly by lowering body fat. The limited available evidence further indicates that exercise intervention may improve some cardiometabolic risk factors.

The role and potential of community-based cancer care for Maori in Aotearoa/New Zealand.

AIM: To investigate the contribution to cancer care and prevention by Maori health provider organisations (MHPs) in Aotearoa/New Zealand. METHODS: A nationwide postal survey of all MHPs (n=253) was undertaken in 2011. The response rate was 55%. RESULTS: We found that MHPs are delivering a wide range of programmes including cancer prevention services focussed on health promotion, advocacy, information and support. MHPs identified financial hardship, transport difficulties, and lack of information as the greatest barriers to cancer care. Culturally safe care by mainstream providers would improve cancer service provision overall. The importance of trust and long-term relationships, with a focus on families rather than individual-based care, was highlighted. CONCLUSION: These findings could lead to substantial improvements in quality of life for Maori cancer patients. This is the first study to show how indigenous health providers contribute to cancer care and prevention in Aotearoa/New Zealand.
