Proximal and distal influences on dietary change among a diverse group with prediabetes participating in a pragmatic, primary care nurse-led intervention: a qualitative study.

OBJECTIVE: To understand motivators, facilitators and challenges to dietary change amongst a diverse sample of New Zealanders with prediabetes participating in a primary care nurse-led individualised dietary intervention. DESIGN: A qualitative study involving semi-structured, face-to-face interviews with a stratified sample of adults with prediabetes and BMI ≥ 25 kg/m2, purposefully selected from a larger 2-year primary care-based prediabetes dietary intervention study. Thematic analysis was undertaken. A socio-ecological model guided interpretation. SETTING: Hawke's Bay, Aotearoa/New Zealand, April 2018-March 2020. PARTICIPANTS: Fifty-eight people aged 28-69 years, with similar numbers of men and women, indigenous Maori and non-Maori, and those who had and had not regressed to normoglycaemia at 6 months. RESULTS: Motivators for wanting to make dietary changes were determination not to progress to diabetes; wanting to be healthy and contribute to others and encouragement by others. Facilitators for adopting and maintaining changes were a strong desire to be healthy; personal determination and feeling supported. Challenges were compromised control over life and environmental factors; feeling unsupported by others; social occasions; financial constraints and living with other health conditions. Developing their own strategies to overcome challenges was empowering, enabling a sense of control. These factors were similar across demographic and glycaemic outcome groups. CONCLUSIONS: Influences on dietary change involved personal, interpersonal, organisational, environmental and policy factors. Although findings appeared similar across groups, dietary interventions need to address the specific ways motivators, facilitators and challenges manifest for individuals and social groups and be tailored accordingly within the context of the wider obesogenic and socio-economic environment.

Understanding the experiences, perspectives and values of indigenous women around smoking cessation in pregnancy: systematic review and thematic synthesis of qualitative studies.

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 Maori 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.

Experiences, perspectives and values of Indigenous peoples regarding kidney transplantation: systematic review and thematic synthesis of qualitative studies.

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.

Ngati and healthy: translating diabetes prevention evidence into community action.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is a major health issue in New Zealand Maori. Clinical trials have demonstrated potential for the prevention of T2DM, but whether community public health programmes aiming to prevent diabetes are effective is untested. OBJECTIVE: To describe the planning and design of an intervention aiming to translate T2DM prevention clinical trial evidence into a community-wide population health intervention in a high risk predominantly Maori community. APPROACH: Community concerns about the diabetes burden were heard by the local diabetes nurse, herself a tribal member, and discussed with a locally raised academic. Project planning ensued. The intervention and its evaluation were designed using a participatory community development model. The planned intervention had three components: community-wide health promotion initiatives conveying healthy lifestyle messages, community education and monitoring for identified high-risk individuals and their extended families, and a structural strategy aimed at adapting local environments to support lifestyle changes. The evaluation plan involved interrupted time series surveys coupled with formative and process evaluations rather than a randomised control trial design. DISCUSSION: Consulting communities, validating community concerns and prioritising cultural and ethical issues were key steps. Time spent developing good relationships amongst the health provider and academic research team members at the outset proved invaluable, as the team were united in addressing the project planning and implementation challenges, such as funding obstacles that arose because of our ethically and culturally appropriate non-randomised control trial evaluation design. The pre-intervention survey demonstrated high rates of diabetes (13%), insulin resistance (33%) and risk factors, and provided evidence for positive, as opposed to negative, lifestyle intervention messages. CONCLUSION: Community-wide lifestyle interventions have the potential to reduce rates of type 2 diabetes and other chronic diseases in high-risk communities, but require a high level of commitment from the health sector and buy-in from the community. Adequate commitment, leadership, planning and resources are essential.

Sudden unexpected infant death in Auckland: a retrospective case review.

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 Maori 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 Maori and Pacific communities.

Two-year results from a community-wide diabetes prevention intervention in a high risk indigenous community: the Ngati and Healthy project.

We describe changes in markers and prevalence of glucose metabolism disorders following a 2-year community-wide intervention aimed at reducing insulin resistance (IR) prevalence in a high risk community. Surveys were undertaken before and 2 years after implementation of a community developed and led diabetes prevention program. Proportions and means were calculated and compared by sex and age groups: 25-49 years and 50+ years. A process evaluation contributed to interpretation of results. Response rates were around 50% and demographic characteristics similar in both surveys. Overall, IR prevalence decreased markedly from 35.5% to 25.4% (p=0.003). Most changes were observed amongst 25-49 years old women for whom there was a significant change in prevalences of IR and glucose metabolism disorders (p=0.015), largely due to reduced IR prevalence (38.2-25.6%). In 2006, 60.3% achieved minimum recommended exercise levels and 65.4% ate wholegrain bread compared with 45.1% (p=0.002) and 42.2% (p=0.044), respectively, in 2003. Participation in a community diabetes prevention intervention appeared to reduce IR prevalence after 2 years in those with the highest level of participation and most marked lifestyle changes.

Insulin resistance and impaired glucose metabolism in a predominantly Maori community.

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.
