Sustaining youth physical activity in times of challenge and change: lessons from COVID-19.

Physical activity (PA) is recognized as essential for positive physical and mental well-being in young people. However, participation in PA is known to decline as adolescents emerge into adulthood under the influence of complex social and structural factors. Globally, COVID-19 restrictions resulted in changes to PA and PA participation levels in youth populations, providing a unique opportunity for gaining insight into PA barriers and enablers in circumstances of challenge, limitation and change. This article details young people's self-reported PA behaviours during the 4-week 2020 COVID-19 lockdown in New Zealand. Taking a strengths-based view and drawing on the COM-B (capabilities, opportunity and motivation behaviour) model for behaviour change, the study explores factors enabling young people to sustain or increase PA during lockdown. Findings are drawn from qualitative-dominant mixed-methods analyses of responses to an online questionnaire: New Zealand Youth Voices Matter (16-24 years; N = 2014). Key insights included the importance of habit and routine, time and flexibility, social connections, incidental exercise and awareness of links between PA and well-being. Of note were the positive attitudes, creativity and resiliency demonstrated as young people substituted or invented alternatives to their usual PA. PA needs to change to adapt to new circumstances over the life course, and youth understanding and knowledge of modifiable factors may provide support for this. Thus these findings have implications for sustaining PA during late adolescence and emerging adulthood, a life phase that can be associated with significant challenge and change.

Understanding the importance of the early-life period for adult health: a systematic review.

Evidence clearly indicates that the nutritional and non-nutritional environment and level of physical activity during the early-life period from preconception through infancy has a lifelong impact on the child's health. However this message must be communicated effectively to parents and other stakeholders such as grandparents, health professionals, policymakers and the wider community in order for positive change to occur. This systematic review explores how both awareness and understanding of the long-term effects of the early-life environment have been measured in various populations and whether any patterns are evident. Ten articles were retrieved via a search of Embase, Medline and Scopus databases for peer-reviewed studies designed to assess participants' knowledge of the links between early-life exposures and adult health. Eligible articles spanned a wide range of countries, population groups and research methods. Three common themes were identified using thematic analysis: 1. a tendency for researchers to conflate participant understanding of the issue (the WHY) with a knowledge of key phrases and nutrition guidelines (the WHAT); 2. bias in both researchers and participants towards short-term thinking due to difficulty conceptualising long-term risk; and 3. challenges in comprehending the complexity of the evidence resulting in oversimplification and the overemphasis of maternal factors. Taken together these findings underscore the importance of a multi-level, whole-of-society approach to communicating the evidence, with the goal of influencing policy decisions as well as building a foundation of community support for parents and prospective parents to create a healthy early-life environment for the long-term wellbeing of all.

Exploring the Retail Food Environment Surrounding Two Secondary Schools with Predominantly Pacific Populations in Tonga and New Zealand to Enable the Development of Mapping Methods Appropriate for Testing in a Classroom.

Rates of noncommunicable diseases (NCDs) are disproportionately high among people of Pacific ethnicity. Nutrition-related environmental exposures including food access and quality contribute to the matrix of factors impacting risk. Preventative interventions in adolescence and the opportunity to integrate health promotion into school-based learning are often overlooked. This study tested the potential of a low-cost method to map the retail food environment in a 1 km radius of two secondary schools in low socioeconomic communities with predominantly Pacific populations, in Tonga and New Zealand (NZ). Mapping utilized Google Earth, Google Maps, government maps, and observations. A rubric was developed to categorize food quality. Outlets within a 1 km radius of each school, (Tonga, n = 150; NZ, n = 52) stocked predominantly unhealthy foods. The NZ data compared favorably to previous studies, indicating the method was valid. The Tongan data is novel and indicates that alternative strategies can be used when access to GIS-type tools is limited. The method produced visual data that has the potential to be analyzed using strategies appropriate for secondary schools. The method should now be tested in classrooms to assess its potential to support school-age students to engage in mapping and critiquing the retail food environment.

Birth Weight and Adolescent Health Indicators in Rarotonga, Cook Islands.

While research into the developmental origins of health and disease (DOHaD) has highlighted the potential of healthy early-life environments for later noncommunicable disease risk reduction, such research is lacking in developing contexts. This study is set in Rarotonga, Cook Islands, a small island developing state in the Pacific-population 17 434. Adult overweight/obesity rates are 89.5%/69.8% and raised blood glucose affects 23.5%. This study investigates early-life associations with later-life health by matching birth weight and adolescent health indicators in Rarotongan-born students from 2016 to 2018. Of 195 students, median age 13 years, 67.7% were overweight/obese, 45.7% had central obesity, and 42.7% had raised blood pressure. A significant inverse association was found between birth weight and central obesity (P = .043). This is the first DOHaD study in a Pacific Island country and demonstrates the importance of prioritizing investment in the early-life environment to optimize later-life health and contribute to reducing the global noncommunicable disease burden.

First 1000 days: New Zealand Mothers' perceptions of early life nutrition resources.

Research into associations between early life nutritional exposures and vulnerability to adult non-communicable disease (NCD) highlights the importance of maternal diet. A booklet outlining evidence-based dietary guidelines for the first 1000 days of life was first published in 2016 by early life nutrition experts for distribution to pregnant women in Australia and New Zealand. First-time New Zealand mothers' (n=9) perceptions of the booklet and its relevance for the future health of their child were explored via semi-structured focus groups and interviews. Recruitment took place via social media channels and antenatal classes around Auckland. Three major themes were identified using thematic analysis: 1. A difference in the ways mothers related to the booklet depending on their apparent level of health literacy and communication preferences; 2. A tendency for women to outsource decision-making to nutrition 'rules', rather than interpreting information to suit personal circumstances; 3. Intense pressure to comply, resulting in feelings of shame or guilt when the 'rules' were not followed. In this study, first-time mums expressed feeling under pressure to 'get it right' and identified a desire for more support from healthcare providers and society. Nutrition education is essential; however, a booklet should provide a starting point for conversation rather than a stand-alone list of recommendations. Further exploration is needed to develop a resource that can be used by health professionals working alongside women and their partners to support healthy child development.

Supporting Cook Island communities to access DOHaD evidence.

Developmental origins of health and disease research have cemented relationships between the early-life environment and later risk of non-communicable diseases (NCDs). However, there is limited translation of this knowledge in developing-economy nations, such as the Cook Islands, that carry exceptionally high NCD burdens. Considering the evidence, Cook Islands leaders identified a need for increased community awareness of the importance of early-life nutrition. Using a community-based participatory research approach, this study aimed to engage Cook Islands community representatives in the co-construction of a contextually relevant early-life nutrition resource. A booklet distributed to mothers in Australia and New Zealand was used as a starting point. Ten semi-structured focus groups (n = 60) explored views regarding the existing resource and options for contextual adaptation. Three core themes were identified: knowledge of the importance of early-life nutrition, recognition of the need for an early-life nutrition resource and the importance of resources being context specific. A draft booklet was created based on these discussions. Participants were invited to give feedback via a second round of focus groups. This confirmed that the voice of the community was represented in the draft booklet. Suggestions for additional material not included in the original resource were also identified. We report on the process and outcomes of the co-construction with community representatives of a resource that has the potential to be used to stimulate community-level discussion about the importance of early-life nutrition. It is crucial that communities have an active voice in research and in making decisions about interventions for their population.

DOHaD in low- and middle-income countries: a systematic review exploring gaps in DOHaD population studies.

Low- and middle-income countries (LMICs) are disproportionately affected by non-communicable diseases (NCDs), accounting for more than 80% of NCD-related deaths globally. Research into early-life influences on these diseases via the developmental origins of health and disease (DOHaD) paradigm has informed health promotion interventions and policies focused on optimising early-life health. However, little is known about where this research occurs and whether it reaches and reflects the countries most affected by NCDs. This review searched for DOHaD studies that investigated relationships between factors during pregnancy and at birth, with later-life NCD incidence, risk and related mortality. The aim of this review was to identify where DOHaD research has been conducted and whether this focus is appropriate and relevant, given the differential burden of NCDs. Embase, MEDLINE and Scopus were searched, and eligibility screening processes identified 136 final articles. This review found that 49.7% of DOHaD research was conducted on populations within Western Europe, 15.9% in East Asia, 12.7% in North America, 8.3% in Latin America and the Caribbean, and fewer in Australasia, South Asia, the Middle East, the Africas, and Central Asia. When categorised by income, this review found that 76.4% of studies were based in high-income countries, 19.1% in upper-middle-income and 4.5% in lower-middle-income countries. No studies were based in low-income countries. There is therefore a marked disconnect between where DOHaD research is undertaken and where the greatest NCD disease burden exists. Increasing DOHaD research capacity in LMICs is crucial to informing local strategies that can contribute to reducing the incidence of NCDs.

Adolescents as agents of healthful change through scientific literacy development: A school-university partnership program in New Zealand.

BACKGROUND: Scientific literacy development is widely emphasized as the overarching goal of science education. It encompasses development of understanding of the nature of science as well as knowledge, attitudes, and values that contribute to empowering adolescents to engage with and make evidence-based decisions about socioscientific issues. Scientific literacy development is enhanced when learning is contextualized in exploration of socioscientific issues.Noncommunicable diseases (NCDs) associated with a combination of obesity and adverse environmental exposures are examples of pressing health-related SSIs facing the world today. Evidence emerging from the field of Developmental Origins of Health and Disease (DOHaD) has identified adolescence as a key life-phase where population-wide education-based interventions that empower teens to engage in science-based health-promoting behaviors could significantly change the course of this epidemic. To achieve this, learning resources that support scientific and health literacy development contextualized in issues linking NCD risk and DOHaD are required.The Healthy Start to Life Education for Adolescents Project is a school-university partnership program designed to support scientific and health literacy development, knowledge translation, and participant-led actions relating to NCD risk prevention. This study assesses the impact of program participation in a cohort of 11-14-year-olds in New Zealand. Evaluation comprised analysis of individually matched questionnaires, pre-, 3 months, and 12 months post-intervention (n = 201) and 6 months post-intervention interviews (n = 40). RESULTS: Positive engagement in science learning occurred. Positive changes in health-related awareness and attitudes 3 months post-intervention were sustained to 12 months. Adolescents reporting pre-intervention dietary behaviors associated with increased obesity risk reported sustained positive behavior changes (p < .001). Qualitative evidence revealed that these changes resulted from application of scientific and health literacy. This has the potential to improve long-term health outcomes for adolescents and their future offspring. Furthermore, feedback from parents demonstrated that adolescents became science communicators within their families. CONCLUSIONS: We demonstrated that contextualized learning promoting scientific and health literacy development facilitated knowledge translation. This allowed adolescents to decide if, and how, to use scientific evidence in relation to their current and future wellbeing. Exploration of the transferability of scientific and health literacy capabilities, and impacts on future health would enhance understanding of the value of the intervention.

School-based primary NCD risk reduction: education and public health perspectives.

The rising global burden of noncommunicable diseases (NCDs) has heightened awareness of the necessity for primary risk prevention programmes. These aim to facilitate long-term behaviour changes in children and adolescents that can reduce NCD risk factors and disease onset in later-life. School-based programmes designed to improve childhood and adolescent health behaviours and wellbeing contribute to this; however, design and impact assessment of these is complex. These programmes should be multidisciplinary, utilizing both educational and health expertise. Health outcomes may not be evident in the short term, but may occur with learning-related behaviour modifications, highly effective when sustained over a lifetime. Thus assessment must analyse short-term learning and behaviour impacts as well as long-term capability, behaviour and health outcomes.The focus of assessment measures in the health and education sectors differs and often lacks depth in one or other area. Educators generally focus on identifying evidence of learning related to capability, attitude and/or behaviour changes, while public health practitioners typically focus on health measures (e.g. body mass index (BMI), mental health, or risk behaviours).We argue that multidisciplinary approaches incorporating education and health viewpoints clarify issues relating to the potential value of schools as a setting to facilitate primary NCD risk reduction. To demonstrate this, we need to: 1) build stronger understandings of the features of effective learning for behavioural change and the best way to evaluate these, and 2) convincingly correlate these measures with long-term metabolic health indicators by tracking learner behaviour and health over time.

Realizing the Potential of Adolescence to Prevent Transgenerational Conditioning of Noncommunicable Disease Risk: Multi-Sectoral Design Frameworks.

Evidence from the field of Developmental Origins of Health and Disease (DOHaD) demonstrates that early life environmental exposures impact later-life risk of non-communicable diseases (NCDs). This has revealed the transgenerational nature of NCD risk, thus demonstrating that interventions to improve environmental exposures during early life offer important potential for primary prevention of DOHaD-related NCDs. Based on this evidence, the prospect of multi-sectoral approaches to enable primary NCD risk reduction has been highlighted in major international reports. It is agreed that pregnancy, lactation and early childhood offer significant intervention opportunities. However, the importance of interventions that establish positive behaviors impacting nutritional and non-nutritional environmental exposures in the pre-conceptual period in both males and females, thus capturing the full potential of DOHaD, must not be overlooked. Adolescence, a period where life-long health-related behaviors are established, is therefore an important life-stage for DOHaD-informed intervention. DOHaD evidence underpinning this potential is well documented. However, there is a gap in the literature with respect to combined application of theoretical evidence from science, education and public health to inform intervention design. This paper addresses this gap, presenting a review of evidence informing theoretical frameworks for adolescent DOHaD interventions that is accessible collectively to all relevant sectors.

Stroke awareness and knowledge in an urban New Zealand population.

BACKGROUND: Stroke is the third most common cause of death and a major cause of chronic disability in New Zealand. Linked to risk factors that develop across the life-course, stroke is considered to be largely preventable. This study assessed the awareness of stroke risk, symptoms, detection, and prevention behaviors in an urban New Zealand population. METHODS: Demographics, stroke risk factors awareness, symptoms, responsiveness, and prevention behaviors were evaluated using a structured oral questionnaire. Binomial logistic regression analyses were used to identify predictors of stroke literacy. RESULTS: Although personal experience of stroke increased awareness of symptoms and their likeliness to indicate the need for urgent medical attention, only 42.7% of the respondents (n = 850) identified stroke as involving both blood and the brain. Educational attainment at or above a trade certificate, apprenticeship, or diploma increased the awareness of stroke symptoms compared with those with no formal educational attainment. Pacific Island respondents were less likely than New Zealand Europeans to identify a number of stroke risk factors. Maori, Pacific Island, and Asian respondents were less likely to identify symptoms of stroke and indicate the need for urgent medical attention. CONCLUSIONS: The variability in stroke awareness and knowledge may suggest the need to enhance stroke-related health literacy that facilitates understanding of risk and of factors that reduce morbidity and mortality after stroke in people of Maori and Pacific Island descent and in those with lower educational attainment or socioeconomic status. It is therefore important that stroke awareness campaigns include tailored components for target audiences.
