ABSTRACT

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.

ABSTRACT

AIMS: A NZ$5 co-payment prescription charge was removed in July 2023 but may be reinstated. Here we quantify the health impact and cost of not being able to afford this charge. METHODS: We linked New Zealand Health Surveys (2013/2014-2018/2019) to hospitalisation data using data available in Integrated Data Infrastructure (IDI). Cox proportional-hazards models compared time to hospitalisation between those who had faced a cost barrier to collecting a prescription and those who had not. RESULTS: Of the 81,626 total survey respondents, 72,243 were available for analysis in IDI. A further 516 were excluded to give an analysis dataset of 71,502. Of these, 5,889 (8.2%) reported not collecting a prescription due to cost in the previous year. Among people who faced a cost barrier, 60.0% (95% confidence interval [CI] 58.7-61.2%) were admitted to hospital during the study period, compared to 43.9% (95% CI 43.6-44.3%) of those who did not. Having adjusted for socio-demographic variables, people who faced a cost barrier were 34% (hazard ratio 1.34; 95% CI 1.29-1.39) more likely to be admitted to hospital than those who did not. Annual avoidable hospitalisation costs-were prescription co-payments to remain free-are estimated at $32.4 million per year based on the assumption of a causal relationship between unmet need for prescription medicines and subsequent hospitalisation. CONCLUSIONS: The revenue to the health system from co-payments may be offset by the costs associated with avoidable hospitalisations.

ABSTRACT

BACKGROUND: In Aotearoa New Zealand, co-payments to see a general practitioner (GP, family doctor) or collect a prescription are payable by virtually all adults. OBJECTIVE: To examine the extent to which these user co-payments are a barrier to accessing health care, focussing on inequities for indigenous Maori. METHODS: Pooled data from sequential waves (years) of the New Zealand Health Survey, 2011/12 to 2018/19 were analysed. Outcomes were self-reported cost barriers to seeing a GP or collecting a prescription in the previous year. Logistic regression was used to estimate odds ratios (ORs) of barriers to care for Maori compared with non-Maori, sequentially adjusting for additional explanatory variables. RESULTS: Pooled data included 107,231 people, 22,292 (21%) were Maori. Across all years, 22% of Maori (13% non-Maori) experienced a cost barrier to seeing a GP, and 14% of Maori (5% non-Maori) reported a cost barrier to collecting a prescription. The age- and wave-adjusted OR comparing Maori/non-Maori was 1.71 (95% confidence interval [CI]: 1.61, 1.81) for the cost barrier to primary care and 2.97 (95% CI: 2.75, 3.20) for the cost barrier to collecting prescriptions. Sociodemographics accounted for about half the inequity for both outcomes; in a fully adjusted model, age, sex, low income, and poorer underlying health were determinants of both outcomes, and deprivation was additionally associated with the cost barrier to collecting a prescription but not to seeing a GP. CONCLUSIONS: Maori experience considerable inequity in access to primary health care; evidence supports an urgent need for change to system funding to eliminate financial barriers to care.

ABSTRACT

PURPOSE: The COVID-19 pandemic has had significant health, social and economic impacts around the world. We established a national, population-based longitudinal cohort to investigate the immediate and longer-term physical, psychological and economic impacts of COVID-19 on affected people in Aotearoa New Zealand (Aotearoa), with the resulting evidence to assist in designing appropriate health and well-being services for people with COVID-19. PARTICIPANTS: All people residing in Aotearoa aged 16 years or over, who had a confirmed or probable diagnosis of COVID-19 prior to December 2021, were invited to participate. Those living in dementia units were excluded. Participation involved taking part in one or more of four online surveys and/or in-depth interviews. The first wave of data collection took place from February to June 2022. FINDINGS TO DATE: By 30 November 2021, of 8735 people in Aotearoa aged 16+ who had COVID-19, 8712 were eligible for the study and 8012 had valid addresses so were able to be contacted to take part. A total of 990 people, including 161 Tangata Whenua (Maori, Indigenous peoples of Aotearoa) completed one or more surveys; in addition, 62 took part in in-depth interviews. Two hundred and seventeen people (20%) reported symptoms consistent with long COVID. Key areas of adverse impacts were experiences of stigma, mental distress, poor experiences of health services and barriers to healthcare, each being significantly more pronounced among disabled people and/or those with long COVID. FUTURE PLANS: Further data collection is planned to follow-up cohort participants. This cohort will be supplemented by the inclusion of a cohort of people with long COVID following Omicron infection. Future follow-ups will assess longitudinal changes to health and well-being impacts, including mental health, social, workplace/education and economic impacts of COVID-19.

ABSTRACT

Inequities in the provision of accessible primary health care contribute to poor health outcomes and health inequity. This study evaluated inequities in the prevalence and consequences of barriers that children face in seeing a general practitioner (GP) in Aotearoa New Zealand. We analysed data on 5,947 children from the Growing Up in New Zealand longitudinal study cohort on barriers to seeing a GP in the previous year, reported by mothers when their children were aged 24 months and 54 months (in 2011/12 and 2013/14 respectively); and maternal-reported hospitalisations in the year prior to age 54 months. We used logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CIs) for consequences of these barriers. Overall, 4.7% (n = 279) of children experienced barriers to seeing a GP in the year to 24 months and 5.5% (n = 325) in the year to 54 months. At each age, and for each specific barrier studied, barriers were more prevalent among Maori (the indigenous people of Aotearoa New Zealand), and among Pacific, compared to New Zealand European, children. Children facing barriers in the year to age 24 months were twice as likely to be hospitalised in the year to 54 months (OR 2.18, 95%CI: 1.38 to 3.44). When this relationship was analysed by ethnicity, the association was strongest for Maori (OR: 2.92, 95%CI: 1.60 to 5.30), less strong for Pacific (OR 2.01, 95%CI: 0.92 to 4.37) and not present for New Zealand European (OR 1.27, 95%CI 0.39 to 4.12) families. Barriers that children face to seeing a GP have social and cost implications for families and the health system. Changes to the health system, and future health policy, must align with the New Zealand government's obligations under Te Tiriti o [The Treaty of] Waitangi, to ensure that health equity becomes a reality for Maori.

ABSTRACT

OBJECTIVES: Occupation is a poorly characterised risk factor for cardiovascular disease (CVD) with females and indigenous populations under-represented in most research. This study assessed associations between occupation and ischaemic heart disease (IHD) in males and females of the general and Maori (indigenous people of NZ) populations of New Zealand (NZ). METHODS: Two surveys of the NZ adult population (NZ Workforce Survey (NZWS); 2004-2006; n = 3003) and of the Maori population (NZWS Maori; 2009-2010; n = 2107) with detailed occupational histories were linked with routinely collected health data and followed-up until December 2018. Cox regression was used to calculate hazard ratios (HR) for IHD and "ever-worked" in any of the nine major occupational groups or 17 industries. Analyses were controlled for age, deprivation and smoking, and stratified by sex and survey. RESULTS: 'Plant/machine operators and assemblers' and 'elementary occupations' were positively associated with IHD in female Maori (HR 2.2, 95%CI 1.2-4.1 and HR 2.0, 1.1-3.8, respectively) and among NZWS males who had been employed as 'plant/machine operators and assemblers' for 10+ years (HR 1.7, 1.2-2.8). Working in the 'manufacturing' industry was also associated with IHD in NZWS females (HR 1.9, 1.1-3.7), whilst inverse associations were observed for 'technicians and associate professionals' (HR 0.5, 0.3-0.8) in NZWS males. For 'clerks', a positive association was found for NZWS males (HR 1.8, 1.2-2.7), whilst an inverse association was observed for Maori females (HR 0.4, 0.2-0.8). CONCLUSION: Associations with IHD differed significantly across occupational groups and were not consistent across males and females or for Maori and the general population, even within the same occupational groups, suggesting that current knowledge regarding the association between occupation and IHD may not be generalisable across different population groups.

ABSTRACT

OBJECTIVES: This study assessed associations between occupational exposures and ischaemic heart disease (IHD) for males and females in the general and Maori populations (indigenous people of New Zealand). METHODS: Two surveys of the general adult [New Zealand Workforce Survey (NZWS); 2004-2006; n = 3003] and Maori population (Maori NZWS; 2009-2010; n = 2107), with information on occupational exposures, were linked with administrative health data and followed-up until December 2018. Cox proportional hazards regression (adjusted for age, deprivation, and smoking) was used to assess associations between organizational factors, stress, and dust, chemical and physical exposures, and IHD. RESULTS: Dust [hazard ratio (HR) 1.6, 95%CI 1.1-2.4], smoke or fumes (HR 1.5, 1.0-2.3), and oils and solvents (HR 1.5, 1.0-2.3) were associated with IHD in NZWS males. A high frequency of awkward or tiring hand positions was associated with IHD in both males and females of the NZWS (HRs 1.8, 1.1-2.8 and 2.4, 1.1-5.0, respectively). Repetitive tasks and working at very high speed were associated with IHD among NZWS females (HRs 3.4, 1.1-10.4 and 2.6, 1.2-5.5, respectively). Maori NZWS females working with vibrating tools and those exposed to a high frequency of loud noise were more likely to experience IHD (HRs 2.3, 1.1-4.8 and 2.1, 1.0-4.4, respectively). Exposure to multiple dust and chemical factors was associated with IHD in the NZWS males, as was exposure to multiple physical factors in males and females of the NZWS. CONCLUSIONS: Exposures associated with an elevated IHD risk included dust, smoke or fumes, oils and solvents, awkward grip or hand movements, carrying out repetitive tasks, working at very high speed, loud noise, and working with tools that vibrate. Results were not consistently observed for males and females and between the general and Maori populations.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Primary Health Care in Aotearoa New Zealand is mainly funded through capitation-based funding to general practices, supplemented by a user co-payment. Funding is designed in part to keep the costs of care low for key groups in the population who have higher health needs. We investigated changes in the socio-demographic determinants of no-cost and low-cost access to Primary Health Care using data from sequential waves of the New Zealand Health Survey (1996/97-2016/17). Fees paid were self-reported and inflated using CPI-adjustment to the value of the 2018NZD. Over the 20-year study period, there was an increase in the population accessing low-cost care. Access to low-cost care was particularly high for Pacific people, but also higher for Maori and Asian people compared to Other/New Zealand European ethnicities. Area-level deprivation was a stronger predictor of access to low-cost care for non-Maori than for Maori. Although Maori were more likely than non-Maori to access low-cost care at all levels of deprivation, this was less evident in more deprived compared to more affluent areas. Given ongoing reported inequity for Maori being less able to afford primary health care, we suggest that future policies to improve access should be fully aligned with the articles of Te Tiriti o Waitangi and should focus on equity.

ABSTRACT

OBJECTIVES: Obesity among Pasifika people living in New Zealand is a serious health problem with prevalence rates more than twice those of the general population (67% vs 33%, respectively). Due to the high risk of developing obesity for this population, we investigated diet quality of Pacific youth and their parents and grandparents. Therefore, we examined the dietary diversity of 30 youth and their parents and grandparents (n=34) to identify whether there are generational differences in dietary patterns and investigate the relationship between acculturation and dietary patterns. METHODS: The study design of the overarching study was cross-sectional. Face-to-face interviews were conducted with Pasifika youth, parents and grandparents to investigate dietary diversity, that included both nutritious and discretionary food items and food groups over a 7 day period. Study setting was located in 2 large urban cities, New Zealand. Exploratory factor analyses were used to calculate food scores (means) from individual food items based on proportions consumed over the week, and weights were applied to calculate a standardised food score. The relationship between the level of acculturation and deprivation with dietary patterns was also assessed. RESULTS: Three distinctive dietary patterns across all participants were identified from our analyses. Healthy diet, processed diet and mixed diet. Mean food scores indicated statistically significant differences between the dietary patterns for older and younger generations. Older generations showed greater diversity in food items consumed, as well as eating primarily a 'healthy diet'. The younger generation was more likely to consume a 'processed diet'. There was significant association between acculturation and deprivation with the distinctive dietary patterns. CONCLUSION: Our investigation highlighted generational differences in consuming a limited range of food items. Identified dietary components may, in part, be explained by specific acculturation modes (assimilation and marginalised) and high socioeconomic deprivation among this particular study population.

ABSTRACT

New Zealand Maori have a considerably higher incidence of gastric cancer compared to non-Maori, and are one of the few populations worldwide with a higher prevalence of diffuse-type disease. Pathogenic germline CDH1 mutations are causative of hereditary diffuse gastric cancer, a cancer predisposition syndrome primarily characterised by an extreme lifetime risk of developing diffuse gastric cancer. Pathogenic CDH1 mutations are well described in Maori families in New Zealand. However, the contribution of these mutations to the high incidence of gastric cancer is unknown. We have used next-generation sequencing, Sanger sequencing, and Multiplex Ligation-dependent Probe Amplification to examine germline CDH1 in an unselected series of 94 Maori gastric cancer patients and 200 healthy matched controls. Overall, 18% of all cases, 34% of cases diagnosed with diffuse-type gastric cancer, and 67% of cases diagnosed aged less than 45 years carried pathogenic CDH1 mutations. After adjusting for the effect of screening known HDGC families, we estimate that 6% of all advanced gastric cancers and 13% of all advanced diffuse-type gastric cancers would carry germline CDH1 mutations. Our results demonstrate that germline CDH1 mutations are a significant contributor to the high frequency of diffuse gastric cancer in New Zealand Maori.

ABSTRACT

BACKGROUND: Health inequities between indigenous and non-indigenous people are well documented. However, the contribution of differential exposure to risk factors in the occupational environment remains unclear. This study assessed differences in the prevalence of self-reported exposure to disease risk factors, including dust and chemicals, physical factors and organisational factors, between Maori and non-Maori workers in New Zealand. METHODS: Potential participants were sampled from the New Zealand electoral rolls and invited to take part in a telephone interview, which included questions about current workplace exposures. Logistic regression, accounting for differences in age, socioeconomic status and occupational distribution between Maori and non-Maori, was used to assess differences in exposures. RESULTS: In total, 2344 Maori and 2710 non-Maori participants were included in the analyses. Maori had greater exposure to occupational risk factors than non-Maori. For dust and chemical exposures, the main differences related to Maori working in occupations where these exposures are more common. However, even within the same job, Maori were more likely to be exposed to physical factors such as heavy lifting and loud noise, and organisational factors such as carrying out repetitive tasks and working to tight deadlines compared with non-Maori. CONCLUSIONS: This is one of the first studies internationally to compare occupational risk factors between indigenous and non-indigenous people. These findings suggest that the contribution of the occupational environment to health inequities between Maori and non-Maori has been underestimated and that work tasks may be unequally distributed according to ethnicity.

ABSTRACT

Maori, the indigenous people of New Zealand, experience disproportionate rates of stomach cancer, compared to non-Maori. The overall aim of the study was to better understand the reasons for the considerable excess of stomach cancer in Maori and to identify priorities for prevention. Maori stomach cancer cases from the New Zealand Cancer Registry between 1 February 2009 and 31 October 2013 and Maori controls, randomly selected from the New Zealand electoral roll were matched by 5-year age bands to cases. Logistic regression was used to estimate odd ratios (OR) and 95% confidence intervals (CI) between exposures and stomach cancer risk. Post-stratification weighting of controls was used to account for differential non-response by deprivation category. The study comprised 165 cases and 480 controls. Nearly half (47.9%) of cases were of the diffuse subtype. There were differences in the distribution of risk factors between cases and controls. Of interest were the strong relationships seen with increased stomach risk and having >2 people sharing a bedroom in childhood (OR 3.30, 95%CI 1.95-5.59), testing for H pylori (OR 12.17, 95%CI 6.15-24.08), being an ex-smoker (OR 2.26, 95%CI 1.44-3.54) and exposure to environmental tobacco smoke in adulthood (OR 3.29, 95%CI 1.94-5.59). Some results were attenuated following post-stratification weighting. This is the first national study of stomach cancer in any indigenous population and the first Maori-only population-based study of stomach cancer undertaken in New Zealand. We emphasize caution in interpreting the findings given the possibility of selection bias. Population-level strategies to reduce the incidence of stomach cancer in Maori include expanding measures to screen and treat those infected with H pylori and a continued policy focus on reducing tobacco consumption and uptake.

ABSTRACT

Exposure to workplace hazards, such as dust, solvents, and fumes, has the potential to adversely affect the health of people. However, the effects of workplace hazards on health may differ when exposure occurs at different times in the circadian cycle, and among people who work longer hours or who do not obtain adequate sleep. The aim of the present study was to document exposures to workplace hazards across a national sample of New Zealanders, comparing people who work a standard 08:00 -17:00 h Monday-to-Friday working week (Std hours) and those who do not (N-Std hours). New Zealanders (n = 10 000) aged 20-64 yrs were randomly selected from the Electoral Roll to take part in a nationwide survey of workplace exposures. Telephone interviews were conducted between 2004 and 2006, using a six-part questionnaire addressing demographics, detailed information on the current or most recent job (including exposures to a range of workplace hazards), sleep, sleepiness, and health status. N-Std hours were categorised on the basis of: being required to start work prior to 07:00 h or finish work after 21:00 h and/or; having a regular on-call commitment (at least once per week) and/or; working rotating shifts and/or; working night shift(s) in the last month. The response rate was 37% (n = 3003), with 22.2% of participants (n = 656) categorised as working N-Std hours. Industry sectors with the highest numbers of participants working N-Std hours were manufacturing, health and community services, and agriculture, fishing, and forestry. Response rate was 37% (n = 3003) with 22.2% (n = 656) categorised as working N-Std hours. Participants working N-Std hours were more likely to be exposed to all identified hazards, including multiple hazards (OR = 2.45, 95% CI = 2.01-3.0) compared to those working Std hours. Participants working N-Std hours were also more likely to report 'never/rarely' getting enough sleep (OR = 1.38, 95% CI = 1.15-1.65), 'never/rarely' waking refreshed (OR = 1.23, 95% CI = 1.04-1.47), and excessive sleepiness (OR = 1.77, 95% CI = 1.29-2.42). New Zealanders working N-Std hours are more likely to be exposed to hazards in the workplace, to be exposed to multiple hazards, and to report inadequate sleep and excessive sleepiness than their colleagues working a standard 08:00-17:00 h Monday-to-Friday working week. More research is needed on the effects of exposure to hazardous substances outside the usual waking day, on the effects of exposure to multiple hazards, and on the combination of hazard exposure and sleep restriction as a result of shift work.
