Background The prevalence of smoking during pregnancy among indigenous women approaches 50% and is associated with sudden infant death, pregnancy loss, preterm delivery, low birth weight, and anatomical deformity. This study aims to synthesise qualitative studies by reporting experiences, perceptions, and values of smoking cessation among pregnant indigenous women to inform potential interventions. Method A highly-sensitive search of MEDLINE, Embase, PsychINFO, and CINAHL, in conjunction with analysis of Google Scholar and reference lists of related studies was conducted in March 2018. We utilised two methods (thematic synthesis and an indigenous Māori analytical framework) in parallel to analyse data. Completeness of reporting in studies was evaluated using the Consolidated Criteria for Reporting Qualitative Studies (COREQ) framework. Results We included seven studies from Australia and New Zealand involving 250 indigenous women. Three themes were identified. Realising well-being and creating agency included giving the best start to baby, pride in being a healthy mum, female role models, and family support. Understanding the drivers for smoking included the impact of stress and chaos that hindered prioritisation of self-care, the social acceptability of smoking, guilt and feeling judged, and inadequate information about the risks of smoking. Indigenous women strongly preferred culturally responsive approaches to smoking cessation, placing value on programs designed specifically for and by indigenous people, that were accessible, and provided an alternative to smoking. Conclusion Future interventions and smoking cessation programmes might be more effective and acceptable to indigenous women and families when they harness self-agency and the desire for a healthy baby, recognise the high value of indigenous peer involvement, and embed a social focus in place of smoking as a way to maintain community support and relationships. Development and evaluation of smoking cessation programs for pregnant indigenous women and families is warranted.

Rationale & Objective: Community house hemodialysis is a submodality of home hemodialysis that enables patients to perform hemodialysis independent of nursing or medical supervision in a shared house. This study describes the perspectives and experiences of patients using community house hemodialysis in New Zealand to explore ways this dialysis modality may support the wider delivery of independent hemodialysis care. Study Design: Qualitative semi-structured in-depth interview study. Setting & Participants: 25 patients who had experienced community house hemodialysis. Participants were asked about why they chose community house hemodialysis and their experiences and perspectives of this. Analytical Approach: Thematic analysis using an inductive approach. Results: 25 patients were interviewed (14 men and 11 women, aged 31-65 years). Most were of Māori or Pacific ethnicity and in part- or full-time employment. More than two-thirds dialyzed for 20 hours a week or more. We identified 4 themes that described patients’ experiences and perspectives of choosing and using community house hemodialysis: reducing burden on family (when home is not an option, minimizing family exposure to dialysis, maintaining privacy and self-identity, reducing the costs of home hemodialysis, and gaining a reprieve from home), offering flexibility and freedom (having a normal life, maintaining employment, and facilitating travel), control of my health (building independence and self-efficacy, a place of wellness, avoiding institutionalization, and creating a culture of extended-hour dialysis), and community support (building social inclusion and supporting peers). Limitations: Non-Māori and non-Pacific patient experiences of community house hemodialysis could not be explored. Conclusions: Community house hemodialysis is a dialysis modality that overcomes many of the socioeconomic barriers to home hemodialysis, is socially and culturally acceptable to Māori and Pacific people, and supports extended-hour hemodialysis and thereby promotes more equitable access to best practice services. It is therefore a significant addition to independent hemodialysis options available for patients.

Aim The aim of this study was to identify the potential risks and benefits of sleeping infants in a Pēpi-Pod distributed to families with high risk of sudden unexpected death in infancy compared to a bassinet. Methods Forty-five mostly indigenous Māori mothers who were referred by local health providers to receive a Pēpi-Pod were surveyed at recruitment, 1 and 3 months. A sleep study at 1 month included infrared video, oximetry and temperature measures. Results When compared with 89 historical bassinet controls, an intention-to-treat analysis of questionnaires showed no increase in direct bed sharing but demonstrated significantly less sharing of the maternal bedroom at both interviews, with the majority of those not sleeping in the maternal bedroom, actually sleeping in the living room. The 1 month 'as-used' analysis showed poorer maternal sleep quality. The 'as-used' analysis of video data (24 Pēpi-Pod and 113 bassinet infants) also showed no increase in direct bed sharing, head covering or prone/side sleep position. Differences in oxygen saturation were not significant, but heart rate was higher in the Pēpi-Pod infants by 8.37 bpm (95% confidence interval 4.40, 12.14). Time in the thermal comfort zone was not different between groups despite Pēpi-Pod infants being situated in significantly warmer rooms. Conclusions Overall, we found that most differences in infant risk behaviours in a Pēpi-Pod compared to a bassinet were small, with confidence intervals excluding meaningful differences. We noted poorer maternal sleep quality at 1 month. Higher infant heart rates in the Pēpi-Pod group may be related to higher room temperatures. The Pēpi-Pod appears physiologically safe but is associated with lower reported maternal sleep quality.

Background Kidney transplantation is considered best practice treatment for end stage kidney disease (ESKD), however Indigenous patients are substantially less likely to receive either a deceased or live donor kidney transplant than non-Indigenous patients. We describe Indigenous peoples’ experiences and perspectives including traditional values around kidney transplantation to inform international transplant programs. Methods We conducted a systematic review of qualitative studies involving Indigenous adults who have experience with or perceptions of kidney transplantation. We searched MEDLINE, Embase, PsychINFO, and CINAHL, in conjunction with analysis of Google Scholar and reference lists of related studies till July 2019. We utilised thematic synthesis to analyse data. Completeness of reporting in studies was evaluated using the Consolidated Criteria for Reporting Qualitative Studies (COREQ) framework. Results Eight studies involving 225 Indigenous participants were included. Five themes were identified: strong desire for transplantation (seeking normality and freedom from dialysis, wanting to reduce burden of disease within community); lack of partnership in shared decision-making (receiving inadequate information, ineffective communication); barriers to live kidney donation (difficulty asking, apprehension about impact on donor, avoiding additional financial burden and fear of complications); cultural considerations (influence of traditional values and beliefs, reconciling traditional values with pragmatic need); and experiencing lack of cultural competence in clinical care (struggling with prejudice and ignorance, mistrust of clinicians and health system). Conclusion Indigenous participants had a strong desire for a kidney transplant and recognised the need for more readily available kidney transplants for others in their communities with ESKD. However, they faced prejudice and a lack of cultural competence by health workers as well as wider barriers to transplantation in systems that did not support effective and culturally appropriate delivery of information and care. Traditional cultural values also influenced decisions regarding kidney transplantation but such values were moderated when considering transplantation. Transplantation programs need to identify and mitigate barriers, such as the financial burden, promote cultural safety and incorporate traditional values into the promotion of transplantation in order to address inequitable transplantation rates.

IntroductionPre-diabetes is a high-risk state for the development of type 2 diabetes mellitus (T2DM) and cardiovascular disease. Regression to normoglycaemia, even if transient, significantly reduces the risk of developing T2DM. The primary aim of this mixed-methods study is to determine if there are clinically relevant differences among those with pre-diabetes and excess weight who regress to normoglycaemia, those who have persistent pre-diabetes and those who progress to T2DM following participation in a 6-month primary care nurse-delivered pre-diabetes dietary intervention. Incidence of T2DM at 2 years will be examined.Methods and analysisFour hundred participants with pre-diabetes (New Zealand definition glycated haemoglobin 41–49 mmol/mol) and a body mass index >25 kg/m2 will be recruited through eight primary care practices in Hawke’s Bay, New Zealand. Trained primary care nurses will deliver a 6-month structured dietary intervention, followed by quarterly reviews for 18 months post-intervention. Clinical data, data on lifestyle factors and health-related quality of life (HR-QoL) and blood samples will be collected at baseline, 6 months, 12 months and 24 months. Sixty participants purposefully selected will complete a semi-structured interview following the 6-month intervention. Poisson regression with robust standard errors and clustered by practice will be used to identify predictors of regression or progression at 6 months, and risk factors for developing T2DM at 2 years. Qualitative data will be analysed thematically. Changes in HR-QoL will be described and potential cost savings will be estimated from a funder’s perspective at 2 years.Ethics and disseminationThis study was approved by the Northern A Health and Disability Ethics Committee, New Zealand (Ethics Reference: 17/NTA/24). Study results will be presented to participants, published in peer-reviewed journals and presented at relevant conferences.Trial registration numberACTRN12617000591358; Pre-results.

The bassinet-like wahakura is an Indigenous initiative for the prevention of Sudden Unexpected Death in Infancy (SUDI). It was developed by New Zealand Māori in 2005 when Māori were rejecting the ‘stop bedsharing’ SUDI prevention message and the SUDI disparity between Māori and non-Māori had become entrenched. Made of native flax, the wahakura was promoted as a culturally resonant, in-bed safe sleep device that would disrupt the SUDI risk associated with ‘bedsharing where there was smoking in pregnancy’ without relying on smoking cessation. A significant movement of weavers and health professionals grew around the wahakura program. A body of research, including infant care surveys, retrospective case review, qualitative enquiry and a randomised controlled trial comparing wahakura and bassinet safety demonstrated the device’s public health plausibility, acceptability to Māori women and its essential safety. This facilitated the distribution, by District Health Boards, of safe sleep devices, including a related device called the Pēpi-Pod, and safe sleep education to high-risk, mainly Māori, mothers. Infant mortality in New Zealand fell by 29%, primarily among Māori infants, over the period 2009–15, suggesting that Māori cultural concepts, traditional activities and community engagement can have a significant effect on ethnic inequities in infant mortality.

AIM: Post-neonatal mortality rates changed very little from 2000 until recently. There has been a decrease in mortality in New Zealand from 2009 to 2015. This paper describes an infant Safe Sleep programme and postulates it is the cause for the recent decrease in deaths. METHODS: The Safe Sleep programme involved: a focus on preventing accidental suffocation, a blitz approach to SUDI education, the targeted provision of portable infant safe sleep devices (ISSD) and the development of safe sleep policy across all district health boards (DHBs). RESULTS: Participation in the 'blitz approach' education by health professionals exceeded 1 in 23 live births, distribution of Safe Sleep leaflets exceeded 2 for every live birth, and over 16,500 ISSDs have been distributed to vulnerable infants. Post-perinatal mortality fell 29% from 2009 to 2015 (2.8 to 2.0/1000 live births). The fall has been greatest for Māori and in regions with the most intensive programmes. CONCLUSION: The recent fall in post-perinatal mortality has not happened by chance. It is likely that the components of end-stage prevention strategy, a focus on preventing accidental suffocation, the education blitz, the targeted supply of ISSDs, and strengthened health policy, have all contributed to varying degrees.

Background Although breastfeeding duration in New Zealand’s indigenous Māori is shorter than in non-Māori, we know little about barriers or motivators of breastfeeding in this community. The aim of this analysis was to identify predictors for extended duration of breastfeeding amongst participants drawn from predominantly Māori communities in regional Hawke’s Bay. Methods Mother/baby dyads were recruited from two midwifery practices serving predominantly Māori women in mostly deprived areas, for a randomised controlled trial comparing the risks and benefits of an indigenous sleeping device (wahakura) and a bassinet. Questionnaires were administered at baseline (pregnancy) and at one, three and six months postnatal. Several questions relating to breastfeeding and factors associated with breastfeeding were included. The data from both groups were pooled to examine predictors of breastfeeding duration. Results Māori comprised 70.5% of the 197 participants recruited. The median time infants were fully breastfed was eight weeks and Māori women were more likely to breastfeed for a shorter duration than New Zealand European women with an odds-ratio (OR) of 0.45 (95% CI 0.24, 0.85). The key predictors for extended duration of breastfeeding were the strong support of the mother’s partner (OR = 3.64, 95% CI 1.76, 7.55) or her mother for breastfeeding (OR = 2.47, 95% CI 1.27, 4.82), longer intended duration of maternal breastfeeding (OR = 1.02, 95% CI 1.00, 1.03) and being an older mother (OR = 1.07, 95% CI 1.02, 1.12). The key predictors for shorter duration of breastfeeding were pacifier use (OR = 0.28, 95% CI 0.17, 0.46), daily cigarette smoking (OR = 0.51, 95% CI 0.37, 0.69), alcohol use (OR = 0.54, 95% CI 0.31, 0.93) and living in a more deprived area (OR 0.40, 95% CI 0.22, 0.72). Conclusions Breastfeeding duration in this group of mainly Māori women was shorter than the national average. Increasing the duration of breastfeeding by these mothers could be further facilitated by ante and postnatal education involving their own mothers and their partners in the support of breastfeeding and by addressing pacifier use, smoking and alcohol use.

OBJECTIVES: To compare an indigenous sleep device (wahakura) for infants at high risk for sudden unexpected death with a bassinet, for measures of infant sleep position, head covering, breastfeeding, bed-sharing, and maternal sleep and fatigue. METHODS: A total of 200 mainly Māori pregnant women were recruited from deprived areas of New Zealand. They were randomized to receive a bassinet or wahakura and asked to sleep the infant in this device from birth. Questionnaires at 1, 3, and 6 months and an overnight infrared video in the home at 1 month were completed. RESULTS: An intention-to-treat and an “as-used” analysis of questionnaires showed no group differences at 1, 3, and 6 months in infant-adult direct bed-sharing (7% vs 12%, P = .24 at 1 month), and at the 6-month interview, the wahakura group reported twice the level of full breastfeeding (22.5% vs 10.7%, P = .04). Maternal sleep and fatigue were not significantly different between groups. Video identified no increase in head covering, prone/side sleep position, or bed-sharing in the wahakura group, either from intention-to-treat analysis, or when analyzed for actual sleep location. CONCLUSION There were no significant differences in infant risk behaviors in wahakura compared with bassinets and there were other advantages, including an increase in sustained breastfeeding. This suggests wahakura are relatively safe and can be promoted as an alternative to infant-adult bed-sharing. Policies that encourage utilization are likely to be helpful in high-risk populations.

Aim: To review autopsy reports of all SUDI deaths in the Auckland region, New Zealand, from October 2000 to December 2009. Methods: Information on all SUDI cases from 2000 to 2009 was extracted from autopsy and police reports from the National Forensic Pathology Service at Auckland Hospital. Results: Of the 332 post-mortems in this period, 221 were classified as SUDI. Of these, 83% were Māori or Pacific infants. The median age at death was 11 weeks and 11% occurred in 7- to 28-day-olds. At the time of death, 64% overall were bedsharing; this was more common in 7–28 day olds (92%). Bedsharing infants were significantly younger at death than non-bedsharing infants (p = 0.008). Where sleep position was known, 57% were placed in non-supine at the last sleep. There was no evidence of diagnostic shift and the prevalence of bedsharing did not change over the decade. Conclusions: Bedsharing was associated with a high proportion of SUDI cases, especially in the youngest infants, and non-supine sleep positions were common. There is a need to enhance SUDI prevention messages and consider innovative ways of promoting safe sleeping environment and supine sleep position in Māori and Pacific communities.

Background: The suggestion that body mass index (BMI) cutoffs to define obesity should differ in persons of Polynesian descent compared with Europeans is based principally on the observation that persons of Polynesian descent have a relatively higher propor- tion of lean body mass for a given BMI. Objectives: The objectives were to determine whether the relation between BMI, waist circumference, and metabolic comorbidity dif- fers in the 2 major ethnic groups in New Zealand and to ascertain whether ethnicity-specific BMI and waist circumference cutoffs for obesity are justified for Maori (indigenous New Zealanders). Design: Subjects included a convenience sample of 1539 men and women aged 17-82 y (47% Maori, 53% white) with measures of BMI, waist circumference, blood pressure, fasting insulin, glucose, and lipids. The sensitivity and specificity of BMI (in kg/m 2 ; 30 and 32), waist circumference (80 and 88 cm in women, 94 and 102 cm in men), and waist-to-height ratio (WHtR 0.6) in relation to in- sulin sensitivity, insulin resistance, and the metabolic syndrome were determined. Receiver operating characteristic curves and areas under the curve (AUCs) were also calculated. Results: No ethnic or sex differences in AUCs were observed for BMI, waist circumference, or WHtR, which showed that these an- thropometric measures perform similarly in Maori and European men and women and correctly discriminate between those with and without insulin resistance or the metabolic syndrome 79-87% of the time. Any increase in specificity from a higher BMI cutoff of 32 in Maori was offset by appreciable reductions in sensitivity. Conclusion: These findings argue against having different BMI or waist circumference cutoffs for people of Polynesian descent. Am J Clin Nutr doi: 10.3945/ajcn.2010.29317.

Maori babies in Aotearoa/New Zealand die of Sudden Infant Death Syndrome (SIDS) at over five times the rate of their non-Maori peers. Research and health promotion around modifiable risk factors has produced only a small improvement in this situation since the mid-1990s. This paper reports on life story interviews, conducted between 2002 and 2004, with nineteen mothers of Maori infants who have died of SIDS. Potential participants were identified and accessed with the support of the national Maori SIDS Prevention Programme care-workers, in both urban and rural locations throughout both main islands of New Zealand. The paper articulates, in a thematic fashion, the bereaved mothers' experiences of alienation, marginalisation and exclusion, as a testimony of lives lived under conditions of serious deprivation in an affluent society. Constructing these experiences as non-modifiable risk factors hinders the development of policy and health promotion interventions that could improve the conditions in which Maori mothers live and raise their babies. It is argued that new approaches that target those whose lives are described here and build on the WHO Social Determinants of Health framework are vital to the efforts of New Zealanders to attain health equity and stem the tide of devastating and preventable loss of Maori babies to SIDS.

We sought to identify lifestyle behaviours which influence risk of impaired glucose metabolism, IGM (newly diagnosed type 2 diabetes, impaired glucose tolerance [IGT] or impaired fasting glycemia [IFG]) or insulin resistance (IR) in a predominantly Maori community, and applied the McAuley formula to determine whether it predicts high risk individuals amongst this community. Three hundred and seventy one participants completed a lifestyle and dietary behaviour questionnaire and oral glucose tolerance test. Clinical variables, microalbuminuria, fasting glucose, insulin and lipids were measured. Diabetes, IFG and IGT were defined according to WHO criteria. IR was defined using the McAuley formula. Those with IGM and those with IR showed similar risk factor attributes. Odds ratios (95% CI) for development of IGM and IR were 0.43 (0.21-0.88) and 0.51 (0.33-0.80), respectively, for regular physical activity, and 0.55 (0.26-1.15) and 0.59 (0.37-0.96), respectively, for two or more dietary behaviours characterized by a high intake of fibre. Regular physical activity and a diet characterized by a high intake of dietary fibre were found to reduce risk of newly diagnosed IGM or IR. The McAuley formula appears to predict high-risk individuals in a predominantly Maori population as it does in European populations.

Background Sudden Unexpected Death in Infancy (SUDI) has persistent high rates in deprived indigenous communities and much of this mortality is attributable to unsafe sleep environments. Whilst health promotion worldwide has concentrated on avoidance of bedsharing, the indigenous Māori community in New Zealand has reproduced a traditional flax bassinet (wahakura) designed to be used in ways that include bedsharing. To date there has been no assessment of the safety of this traditional sleeping device. Methods/Design This two arm randomised controlled trial is being conducted with 200 mother-baby dyads recruited from Māori communities in areas of high deprivation in the Hawkes Bay, New Zealand. They are randomised to wahakura or bassinet use and investigation includes questionnaires at baseline (pregnancy), when baby is 1, 3, and 6 months, and an overnight video sleep study at 1 month with monitoring of baby temperature and oxygen saturation, and measurement of baby urinary cotinine and maternal salivary oxytocin. Outcome measures are amount of time head covered, amount of time in thermal comfort zone, number of hypoxic events, amount of time in the assigned sleep device, amount of time breastfeeding, number of parental (non-feed related) touching infant events, amount of time in the prone sleep position, the number of behavioural arousals and the amount of time infant is awake overnight. Survey data will compare breastfeeding patterns at 1, 3, and 6 months as well as data on maternal mind-mindedness, maternal wellbeing, attachment to baby, and maternal sleep patterns. Discussion Indigenous communities require creative SUDI interventions that fit within their prevailing world view. This trial, and its assessment of the safety of a wahakura relative to a standard bassinet, is an important contribution to the range of SUDI prevention research being undertaken worldwide.

This paper describes and compares the infant care practices and beliefs of Maori, Tongan, Samoan, Cook Islands, Niuean and Pakeha (European) caregivers residing in Auckland, New Zealand. Focusing on four areas--sources of support and advice; infant feeding; infant sleeping arrangements; and traditional practices and beliefs--it explores inter-ethnic similarities and differences and intra-ethnic tensions. The international literature indicates that there can be significant cultural variation in infant care practices and in the meanings attributed to them. There is, however, little New Zealand literature on this topic, despite its importance for effective health service and health message delivery. Participants were primary caregivers of infants under 12 months. An average of six focus groups were conducted within each ethnic group, resulting in a total of 37 groups comprising 150 participants. We found similarities across all ethnic groups in the perceived importance of breastfeeding and the difficulties experienced in establishing and maintaining this practice. The spectrum of behaviours ranged widely with differences most pronounced between Pacific caregivers, especially those Island-raised, and Pakeha caregivers, especially those in nuclear families. Amongst the former, norms included: the family as central in providing support and advice; infant bedsharing; abdominal rubbing during pregnancy; baby massage; and the importance of adhering to traditional protocols to ensure infant well-being. Amongst the latter, norms included: strong reliance on professional advice; looser family support networks; the infant sleeping in a cot; and adherence to Western biomedical understandings of health and illness. Maori caregivers bridged the spectrum created by these groups and exhibited a diverse range of practices. Intra-cultural differences were present in all groups indicating the dynamic nature of cultural practices. They were most evident between Pacific-raised and New Zealand-raised Pacific caregivers, with the latter attempting to marry traditional with Western beliefs and practices.

EDITOR,—Charles Essex implies that the cot death rate has failed to fall in the Maori community because “advice not to share the bed has alienated leaders of some ethnic groups, who claim that it goes against traditional infant care practices.”1 Essex seems to be placing the blame directly on to the Maori community and absolving the public health system for its failure to deal with cot death among Maori. The higher cot death rate in Maori than non-Maori since the …

OBJECTIVES: The aim of this study was to compare perceptions of body size in European, Maori and Pacific Islands people with measured body mass index (BMI), waist-to-hip ratio and change in BMI since age 21 y. Socio-demographic factors that influenced perceptions of body size were also investigated. DESIGN: Cross-sectional survey. METHODS: Participants were 5554 workers, aged ≥40 y, recruited from companies in New Zealand during 1988–1990. RESULTS: Prevalences of BMI>25 kg/m2 were: Europeans, 64.7% men, 47.2% women; Maori, 93.2% men, 80.6% women; and Pacific Islanders, 94.1% men, 92.9% women. Similarly, prevalences of BMI > 30 kg/m2 were: Europeans, 14.4% men, 14.6% women; Maori, 55.0% men, 41.9% women; and Pacific Islanders, 55.1% men, 71.7% women. At each perception of body size category, Maori and Pacific Islands men and women had a higher BMI than European men and women, respectively. BMI increased with increasing perception of body size in all gender and ethnic groups. Since age 21, increases in BMI were highest in Pacific Islands people and increased with increasing perceptions of body size category in all ethnic and gender groups. BMI adjusted odds (95% CI) of being in a lower perception category for body size were 1.70 (1.38–2.12) in Maori and 8.99 (7.30–11.09) in Pacific people compared to Europeans, 1.27 (1.13–1.42) times higher for people with no tertiary education, 1.41 (1.25–1.59) times higher in people with low socioeconomic status, and 0.94 (0.92– 0.95) for change in BMI since age 21. CONCLUSION: Nutritional programs aimed at reducing levels of obesity should be ethnic-specific, addressing food and health in the context of their culture, and also take into account the socioeconomic status of the group. On the population level, obesity reduction programs may be more beneficial if they are aimed at the maintenance of weight at age 21.
