    Political polarization and wellbeing: Investigating potential intrapersonal harm From affective polarization
    (Ubiquity Press, 2025-12-01) McMurtrie B; Roemer A; Philipp M; Hebden R; Williams M
    Affective polarization—antipathy towards members of one’s political out-group—may pose challenges to social cohesion and personal wellbeing. Prior studies have suggested that one’s affective polarization may cause intrapersonal harm as well as interpersonal harm. It has been associated with reduced social support, increased stress, and worse physical health. This pre-registered study investigated the intrapersonal harm of affective polarization using a six-wave longitudinal survey (N = 470). Affective polarization, social support, perceived stress, and self-rated health were measured fortnightly for three months preceding the 2024 US presidential election. Random intercept cross-lagged panel models were employed to investigate the within-person effects of affective polarization on these indicators of wellbeing. Contrary to hypotheses, none of the hypothesized cross-lagged effects were significant, suggesting that changes in affective polarization did not predict changes in social support, stress, or health. However, cross-sectional analyses did reflect past findings, showing that higher levels of affective polarization were associated with lower social support, greater stress, and worse health. We additionally found evidence for perceived stress causing moderate increases in affective polarization. Stable differences by political orientation were also observed in our sample, with liberals reporting higher affective polarization and stress, lower social support, and worse health. Despite the lack of significant effects, potentially due to limitations such as sample size and measurement constraints, our findings underscore the importance of further investigations with appropriate robust designs to clarify the relationship between affective polarization and wellbeing. These results challenge the assumption that affective polarization directly drives declines in wellbeing.

    Perspectives on health and illness
    (Massey University, 2025-07-16) Morison T; Gibson A; Riley S; McGuigan K
    Taking a critical perspective, as we do in this book, involves going beyond the surface appearance of an idea or phenomenon to determine why it is the way it is (Baum, 2015). For (critically oriented) health psychology, this means scrutinising health-related issues through a lens that questions underlying assumptions, power dynamics, and social structures. It also means questioning our very understanding of the notion of health, which we frequently take for granted, and which is the focus of this chapter. The questions that may spring to mind are: What is the point of recognising and unpacking different, changing understandings of health and illness? And, Why is taking this critical perspective necessary or valuable? This chapter tackles these questions.

    Investigation of Advertising and Food Environment Surrounding Primary Schools in New Zealand
    (John Wiley and Sons Australia Ltd on behalf of Australian Health Promotion Association, 2025-10-01) Nicholls K; Ali A; Wham C
    Objective: The objective of this study is to examine food and beverage advertising and stores around New Zealand (NZ) primary schools. Methods: Food and beverage advertising and stores within 800 m of 18 primary schools in NZ were collected in August 2023. Food and beverage advertising and store characteristics were compared across low (1–3), medium (4–7) and high (8–10) decile schools, reflecting socioeconomic status. Results: ‘Non-core’ food and beverage advertisements (n = 426, 89%) outnumbered ‘core’ (n = 53, 11%) with sugar-sweetened beverages (n = 192, 40.1%) the most common category, and Coca-Cola the most common brand (n = 158, 33%, p = 0.033). Food stores were the most common location for food and beverage advertisements (97.1%, p ≤ 0.001). More food and beverage advertisements surrounded low (n = 406, 43%) and medium (n = 208, 43.4%) decile schools, with low-decile schools having more nearby advertisements (0–400 m) (n = 111, 57.5%). The most common food and beverage stores near schools were local fast-food (44.7%) and convenience stores (24.2%). Store type varied by school decile, with more convenience stores (51.9%) and fast-food chains (81.3%) near low-decile schools. Conclusions: ‘Non-core’ food and beverage advertising, local fast-food, fast-food chains and convenience stores were prevalent surrounding primary schools, particularly low and medium-decile schools. So What? These findings highlight high levels of exposure to unhealthy food and beverage advertising and food stores, especially surrounding schools within low and medium socioeconomic areas.

    Low public awareness opens up new opportunities for highlighting milk as an iodine dietary source.
    (Elsevier B.V., 2024-09-17) Niero G; Censi S; Mian C; Manuelian CL; Rovai M; Tsiplakou E; da Costa L; Fuerst-Waltl B; Cruz AG; Berry DP; Lopez-Villalobos N; Masi A; Rakwal R; Hambardzumyan G; Borrisser-Pairó F; Koczura M; Trujillo Rojas LM; Albanell E; Rivera SG; González-Luna S; Berard J; De Marchi M
    This international survey provides insights into public awareness of the importance of iodine as an essential trace mineral in human health along with knowledge of iodine dietary sources. The online questionnaire included sociodemographic aspects and dietary iodine consumer awareness on 7-point Likert-type questions. A total of 4,704 questionnaires from 16 countries were considered. Answers were analyzed through a multiple regression linear model including country, gender, age, education level, and employment status as fixed effects. Respondents were moderately aware of the importance of fish (4.86) and seafood (4.90) as dietary iodine sources, but less aware of milk as a primary iodine source (3.32). Respondent awareness varied considerably across countries. Age, education level, and employment status only modified their perception when asked about fish and seafood as a source of iodine, with elderly respondents, those highly educated and of working age being more aware of their relevance as dietary iodine sources. Respondent knowledge did not vary by age, education level, employment status, or gender when asked about cereals, vegetables and fruits, meat and milk as iodine-rich food sources. Consequently, labeling milk and dairy products as an iodine-rich food source should be considered. Public authorities can consider the results from this survey in promotional campaigns to improve the awareness of different iodine sources and their beneficial effect on health.

    Exploring the Nutrition-Related Health of the Ageing Population in Fiji: A Narrative Review.
    (SAGE Publications, 2024-10-18) Naliva S; Kruger M; Havea P; Wham C
    Fijis' older population aged 55 years and over makes up 14% of the total population and is expected to reach 20% by 2050. This narrative review aimed to examine the health and nutrition status of the aging population of Fiji and sociodemographic determinants. A search strategy was conducted throughout databases, and gray literature from relevant websites was searched. Due to the limited evidence regarding the nutrition, health, and socio-economic factors that impact the aging population in Fiji the inclusion criteria were broad and included both genders (male and female), all publications up until December 2022, all study designs, and gray literature (government/institutional reports, conference proceedings, guidelines, Act, and Policies) . There was no filter for date applied in the search criteria. Studies that did not meet the search criteria were excluded. 20 documents including published articles were included for analysis and result synthesis. Life expectancy at birth for the Fiji population is 68 years. A significant annual increase in mortality rate from endocrine, nutritional, and metabolic diseases has been observed in women aged 75+ but not older men. Women of low-income status are more at risk than men. However, as most investigations aggregate those ≥18 years, there is a lack of information on older adults (≥65 years) health and nutrition status. To improve the health status of older adults, an understanding of the nutritional status of older adults is warranted, especially concerning lifestyle and sociodemographic determinants.

    The role of meat in the human diet: evolutionary aspects and nutritional value
    (Oxford University Press on behalf of the American Society of Animal Science, 2023-04-15) Leroy F; Smith NW; Adesogan AT; Beal T; Iannotti L; Moughan PJ; Mann N
    Implications Aspects of human anatomy, digestion, and metabolism diverged from other primates, indicating evolutionary reliance on, and compatibility with, substantial meat intake. Implications of a disconnect from evolutionary dietary patterns may contribute to today’s burden of disease, increasing the risk for both nutrient deficiencies and chronic diseases. Meat supplies high-quality protein and various nutrients, some of which are not always easily obtained with meat-free diets and are often already suboptimal or deficient in global populations. Removal of meat comes with implications for a broad spectrum of nutrients that need to be accounted for, whereas compensatory dietary strategies must factor in physiological and practical constraints. Although meat makes up a small part (<10%) of global food mass and energy, it delivers most of the global vitamin B12 intake and plays a substantial role in the supply of other B vitamins, retinol, long-chain omega-3 fatty acids, several minerals in bioavailable forms (e.g., iron and zinc), and a variety of bioactive compounds with health-improving potential (e.g., taurine, creatine, and carnosine). As a food matrix, meat is more than the sum of its individual nutrients. Moreover, within the diet matrix, it can serve as a keystone food in food-based dietary interventions to improve nutritional status, especially in regions that rely heavily on cereal staples. Efforts to lower global meat intake for environmental or other reasons beyond a critical threshold may hinder progress towards reducing undernutrition and the effects this has on both physical and cognitive outcomes, and thereby stifle economic development. This is particularly a concern for populations with increased needs and in regions where current meat intake levels are low, which is not only pertinent for the Global South but also of relevance in high-income countries.

    Using ‘Health’ to Promote Older Adults’ Digital Health Literacy
    (European Society of Medicine, 2024-07-01) Lockhart C; Hunter I
    Aim: This project explored requirements for digital learning to support digital health literacy of older adults within a rural region. Method: A qualitative study with purposeful sampling and thematic analysis of data. Interviews were held with ten digital educators and seven older adults (four with low vision) living and/or working in rural New Zealand. Results: All participants recognised the importance of trust and having the right people to provide support and foster positive engagement with digital technologies. The digital educators recognised a missed opportunity to engage older adults using health as a topic for digital learning. Conclusion: A positive experience with learning to use digital technologies is necessary to facilitate digital health literacy for older adults. Digital educators want access to reputable resources to promote health websites; many don’t know these exist. A wide range of digital literacy learning services exist which need to be better promoted in hard copy and online. The authors recommend building on older adults’ existing relationships, engaging with community groups, providing pop-up sessions, and running events to increase digital technological knowledge and engage with health information online. The key is utilising the right people to support the older adult with opportunities for digital skills uptake

    He Kāinga Oranga: reflections on 25 years of measuring the improved health, wellbeing and sustainability of healthier housing
    (Taylor and Francis, on behalf of Te Aparangi, The Royal Society of New Zealand, 2023-02-06) Howden-Chapman P; Crane J; Keall M; Pierse N; Baker MG; Cunningham C; Amore K; Aspinall C; Bennett J; Bierre S; Boulic M; Chapman R; Chisholm E; Davies C; Fougere G; Fraser B; Fyfe C; Grant L; Grimes A; Halley C; Logan-Riley A; Nathan K; Olin C; Ombler J; O’Sullivan K; Pehi T; Penny G; Phipps R; Plagman M; Randal E; Riggs L; Robson B; Ruru J; Shaw C; Schrader B; Teariki MA; Telfar Barnard L; Tiatia R; Toy-Cronin B; Tupara H; Viggers H; Wall T; Wilkie M; Woodward A; Zhang W
    This paper reflects on the influences and outcomes of He Kāinga Oranga/Housing and Health Research Programme over 25 years, and their impact on housing and health policy in Aotearoa and internationally. Working in partnership particularly with Māori and Pasifika communities, we have conducted randomised control trials which have shown the health and broad co-benefits of retrofitted insulation, heating and remediation of home hazards, which have underpinned government policy in the Warm Up NZ-Heat Smart programme and the Healthy Homes Standards for rental housing. These trials have been included as evidence in the WHO Housing and Health Guidelines and led to our designation as a WHO Collaborating Centre on Housing and Wellbeing. We are increasingly explicitly weaving Māori frameworks, values and processes with traditional Western science.

    Owner-Reported Health Events in Australian Farm Working Dogs.
    (MDPI (Basel, Switzerland), 2024-06-27) Pattison NA; Isaksen KE; Cogger N; Dorman DC
    Working farm dogs are an integral part of livestock farming in Australia but, currently, no studies have investigated their overall health. This study aimed to identify the prevalent diseases and injuries among these dogs, offering a baseline dataset. A total of 125 farm dog owners were recruited at a public working dog event and interviewed about the health of their dogs in the preceding 12 months. Information was provided about 526 dogs. Most dogs were Kelpies, and not neutered. Nine percent of the dogs had been sold, 6% had died, and 1% had been retired. Of the 444 remaining dogs, 24% had a health event in the past 12 months, while 13% had a health event that affected their work. The injuries (11%) mostly involved the musculoskeletal system or skin, while the non-traumatic illnesses (13%) commonly included arthritis. Forty-five percent of the injured dogs and 26% of the ill ones received veterinary treatment. The results indicate similarities to previous studies into working farm dogs. Given their unique challenges, further research is needed to ensure optimal care for farm dogs in Australia

    The United Nations (UN) Card, Identity, and Negotiations of Health among Rohingya Refugees
    (MDPI (Basel, Switzerland), 2023-02-15) Rahman MM; Dutta MJ; Plaza Del Pino FJ; Ugarte-Gurruxaga MI
    Being persecuted and expelled from Myanmar, Rohingya refugees are now distributed throughout the world. The Southeast Asian nation of Malaysia has been a preferred destination for Rohingyas fleeing Myanmar's state-sponsored genocide and more recently in a bid to change their fates from the refugee camps in Bangladesh. Refugees are one of the most vulnerable groups in Malaysia and often face dire circumstances, in which their health and wellbeing are compromised. Amidst a plethora of structural challenges, Rohingya refugees try to claim some of their rights with the aid of the UN card (UNHCR ID cards) in Malaysia. Guided by the culture-centered approach (CCA), this study examined the perspectives and experiences of healthcare among Rohingya refugees while living in Malaysia, now resettled in Aotearoa, New Zealand. The participants' narratives showed that the UN card not only materialized their refugee status in Malaysia but also offered them a way of living in a world where documents anchor the materiality of health.
