Indigenous cultures in countries with similar colonisation histories share the challenge of intergenerational diabetes

Technology advances in diabetes pregnancy: right technology, right person, right time

This review outlines some of the extraordinary recent advances in diabetes technology, which are transforming the management of type 1 diabetes before, during and after pregnancy. It highlights recent improvements associated with use of continuous glucose monitoring (CGM) but acknowledges that neither CGM nor insulin pump therapy are adequate for achieving the pregnancy glucose targets. Furthermore, even hybrid closed-loop (HCL) systems that are clinically effective outside of pregnancy may not confer additional benefits throughout pregnancy. To date, there is only one HCL system, the CamAPS FX, with a strong evidence base for use during pregnancy, suggesting that the pregnancy benefits are HCL system specific. This is in stark contrast to HCL system use outside of pregnancy, where benefits are HCL category specific. The CamAPS FX HCL system has a rapidly adaptive algorithm and lower glucose targets with benefits across all maternal glucose categories, meaning that it is applicable for all women with type 1 diabetes, before and during pregnancy. For women of reproductive years living with type 2 diabetes, the relative merits of using non-insulin pharmacotherapies vs diabetes technology (dipeptidyl peptidase-4 inhibitors, glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors) are unknown. Despite the urgent unmet need and potential benefits, studies of pharmacotherapy and technology use are extremely limited in pregnant women with type 2 diabetes.

Supporting healthy lifestyles for First Nations women and communities through co-design: lessons and early findings from remote Northern Australia

Background

The period before, during, and after pregnancy presents an opportunity to reduce diabetes-related risks, which in Australia disproportionately impact Aboriginal and Torres Strait Islander women. Collaboration with Aboriginal and Torres Strait Islander women/communities is essential to ensure acceptability and sustainability of lifestyle modifications. Using a novel co-design approach, we aimed to identify shared priorities and potential lifestyle strategies. We also reflected on learnings from this approach.

Methods

We conducted 11 workshops and 8 interviews at two sites in Australia's Northern Territory (Central Australia and Top End), using experience-based co-design (EBCD) and incorporating principles of First Nations participatory research. Workshops/interviews explored participant' experiences and understanding of diabetes in pregnancy, contextual issues, and potential lifestyle strategies. Participants included three groups: 1) Aboriginal and Torres Strait Islander women of reproductive age (defined as aged 16-45 years); 2) Aboriginal and Torres Strait Islander community members; and 3) health/community services professionals. The study methodology sought to amplify the voices of Aboriginal women.

Findings

Participants included 23 women between ages 16-45 years (9 with known lived experience of diabetes in pregnancy), 5 community members and 23 health professionals. Key findings related to identified priority issues, strategies to address priorities, and reflections on use of EBCD methodology. Priorities were largely consistent across study regions: access to healthy foods and physical activity; connection to traditional practices and culture; communication regarding diabetes and related risks; and the difficulty for women of prioritising their health among competing priorities. Strategies included implementation of a holistic women's program in Central Australia, while Top End participants expressed the desire to improve nutrition, peer support and community awareness of diabetes. EBCD provided a useful structure to explore participants' experiences and collectively determine priorities, while allowing for modifications to ensure co-design methods were contextually appropriate. Challenges included the resource-intensive nature of stakeholder engagement, and collaborating effectively with services and communities when researchers were "outsiders".

Conclusions

A hybrid methodology using EBCD and First Nations participatory research principles enabled collaboration between Aboriginal women, communities and health services to identify shared priorities and solutions to reduce diabetes-related health risks. Genuine co-design processes support self-determination and enhance acceptability and sustainability of health strategies.

Identifying Relevant Content to Inform a Comprehensive Indigenous Health Curriculum: A Scoping Review

Purpose

To identify the entry-level curricular content related to Indigenous health recommended for entry-level physiotherapy (PT) programs in Canada and other similar countries.

Methods

Design: Scoping review. Procedures: Four electronic databases were searched using the terms physiotherapy, Indigenous health, entry-level curriculum, and their derivatives. Grey literature sources were hand searched and included Canadian PT professional documents, PT Program websites, Truth and Reconciliation Commission (TRC) sources, and a Google search. Data related to curriculum characteristics, methods of delivery, and barriers and facilitators to implementation were extracted from relevant references. Stakeholders reviewed study findings.

Results

Forty-five documents were included. Documents focused on Indigenous peoples in Canada, Aboriginal and Torres Strait Islanders in Australia, and Māori in New Zealand. Canadian PT programs appeared to rely on passive teaching methods while programs in Australia and New Zealand emphasized the importance of partnering and engaging with Indigenous people. Barriers to incorporating indigenous health curriculum included an overcrowded curriculum and difficulty establishing relevance of Indigenous content (i.e., meaning).

Conclusions

Similarities and differences were found between curricula content and approaches to teaching IH in Canada and the other countries reviewed. Strategies to promote greater engagement of Indigenous people in the development and teaching of IH is recommended.

Connecting the Dots of Care: A pilot study linking Aboriginal and/or Torres Strait Islander peoples with diabetes care in hospital, using hospital pharmacists

Background

Diabetes is common among Aboriginal and/or Torres Strait Islander peoples, yet often undetected in hospital.

Objective

To identify how urban hospital pharmacists can detect if Aboriginal and/or Torres Strait Islander patients have diabetes or a higher chance of getting diabetes.

Methods

A multi-methods study used data from patients, and researcher field notes. Aboriginal and/or Torres Strait Islander peoples admitted to hospital over 12-weeks (July-October 2021) were prospectively identified from admissions lists. A hospital pharmacist-researcher visited eligible patients. Consenting participants had their blood glucose and HbA1c checked. Participants with HbA1c > 6.5% (no known diabetes) or 7% (known diabetes) were referred for endocrinology review during their stay. Test results and resultant diabetes plan were shared with their general practitioner. Two days after discharge, participants were called to gauge views on their hospital-based diabetes care. Barcode technology recorded pharmacist time. Voice-recorded field notes were thematically analysed. Ethics approval was obtained.

Results

Seventy-two patients were eligible for inclusion, 67/72 (93%) consented to take part. Sixty-one (91%) patients returned a HbA1c < 6.5, of which, 4/61 (6.5%) returned a HbA1c, 6-6.4. They were contacted to yarn about diabetes prevention. Six of the 67 (9%) qualified for endocrine review, 5 had known diabetes, one newly diagnosed. None were known to endocrinology. All participants telephoned were satisfied with their hospital-based diabetes care. Pharmacist time for initial introductory yarn, consenting process, organisation of HbA1c and results discussion was 20 min or 40 min if referred for endocrine review. Field notes guided understanding of service implementation.

Conclusion

This novel pharmacist-led diabetes screening service for Aboriginal and/or Torres Strait Islander peoples appeared to provide a unique opportunity for screening and referral links in a holistic way. Future research is required to test this model by upscaling to include more pharmacists and other chronic disease screening and referral pathways.

Trauma and Substance Use among Indigenous Peoples of the United States and Canada: A Scoping Review

Substance use has been identified by Indigenous populations as contributing to health disparities facing their communities. Rates of trauma exposure and post-traumatic stress disorder are higher in Indigenous, compared to non-Indigenous, populations and have been linked to substance use. Historical trauma is thought to be one mechanism underlying substance use and related disorders. The purpose of the present study is to summarize the current state of the literature focusing on the association between trauma (historical and lived) and substance use among Indigenous populations in the United States and Canada. Databases were systematically searched using the preferred reporting items for systematic reviews and meta-analyses statement. The search strategy initially yielded 4,026 articles. After exclusion of ineligible articles, 63 articles remained for synthesis. Results of the present review provide evidence for a positive link between substance use and both historical trauma (i.e., 86.4% of studies) and lived trauma (i.e., 84.7% of studies). Indigenous participants reported that historical trauma and pain related to loss of cultural identity contributed to substance use in their communities. Indigenous participants also consistently described an association between lived trauma and substance use. Despite heterogeneity among Indigenous communities, findings suggest a significant association between trauma and substance use across many different tribes and settings (e.g., reservation/reserve, rural/urban). Indigenous participants identified healing from trauma and reconnecting with culture as necessary components for reducing substance use and maintaining sobriety. With this, the development and implementation of interventions should partner with Indigenous communities in a manner that promotes and enhances cultural values for healing.

The impact of diabetes during pregnancy on neonatal outcomes among the Aboriginal population in Western Australia: a whole-population study

BACKGROUND

Aboriginal and Torres Strait Islander (hereafter Aboriginal) women have a high prevalence of diabetes in pregnancy (DIP), which includes pre-gestational diabetes mellitus (PGDM) and gestational diabetes mellitus (GDM). We aimed to characterize the impact of DIP in babies born to Aboriginal mothers.

METHODS

A retrospective cohort study, using routinely collected linked health data that included all singleton births (N = 510 761) in Western Australia between 1998 and 2015. Stratified by Aboriginal status, generalized linear mixed models quantified the impact of DIP on neonatal outcomes, estimating relative risks (RRs) with 95% CIs. Ratio of RRs (RRRs) examined whether RRs differed between Aboriginal and non-Aboriginal populations.

RESULTS

Exposure to DIP increased the risk of adverse outcomes to a greater extent in Aboriginal babies. PGDM heightened the risk of large for gestational age (LGA) (RR: 4.10, 95% CI: 3.56-4.72; RRR: 1.25, 95% CI: 1.09-1.43), macrosomia (RR: 2.03, 95% CI: 1.67-2.48; RRR: 1.39, 95% CI: 1.14-1.69), shoulder dystocia (RR: 4.51, 95% CI: 3.14-6.49; RRR: 2.19, 95% CI: 1.44-3.33) and major congenital anomalies (RR: 2.14, 95% CI: 1.68-2.74; RRR: 1.62, 95% CI: 1.24-2.10). GDM increased the risk of LGA (RR: 2.63, 95% CI: 2.36-2.94; RRR: 2.00, 95% CI: 1.80-2.22), macrosomia (RR: 1.95, 95% CI: 1.72-2.21; RRR: 2.27, 95% CI: 2.01-2.56) and shoulder dystocia (RR: 2.78, 95% CI: 2.12-3.63; RRR: 2.11, 95% CI: 1.61-2.77). Birthweight mediated about half of the DIP effect on shoulder dystocia only in the Aboriginal babies.

CONCLUSIONS

DIP differentially increased the risks of fetal overgrowth, shoulder dystocia and congenital anomalies in Aboriginal babies. Improving care for Aboriginal women with diabetes and further research on preventing shoulder dystocia among these women can reduce the disparities.

A multiple case study of pre-diabetes care undertaken by general practice in Aotearoa/New Zealand: de-incentivised and de-prioritised work

BACKGROUND

In Aotearoa/New Zealand (NZ) general practices diagnose and manage pre-diabetes. This work is important as it has the potential to delay or prevent the onset of Type 2 Diabetes (T2DM), reduce NZ's health inequities, and the burden that T2DM places on health care services. However, no study has previously examined how this work routinely occurs in NZ.

METHODS

Two case studies of practices serving ethnically and socio-economically diverse populations, followed by cross-case analysis.

RESULTS

The NZ health care context including funding mechanisms, reporting targets, and the disease centred focus of care, acted together to dis-incentivise and de-prioritise pre-diabetes care in general practices. The social determinants of health differentially influenced patients' ability to engage with and respond to pre-diabetes care, significantly impacting this work. Differing perspectives about the significance of pre-diabetes and gaps in systematic screening practices were identified. Interventions used were inconsistent and lacked comprehensive ongoing support.

CONCLUSIONS

Complex multi-layered factors impact on pre-diabetes care, and many of the barriers cannot be addressed at the general practice level. The practice serving the most disadvantaged population who concurrently have higher rates of pre-diabetes/T2DM were more adversely affected by the barriers identified.

Enhancing the capacity of the health workforce to deliver best practice diabetes care

Diabetes prevalence is increasing; the technologies and medicines used to manage diabetes have become more complex, and the specialist health workforce with qualifications in diabetes is insufficient. Generalist health professionals have limited diabetes knowledge, despite engaging with people with diabetes in healthcare daily. An innovative framework is needed to align with the Australian National Diabetes Strategy to build a competent, flexible and adaptive workforce to promote excellence in diabetes care. A three-staged modified Delphi technique was used to identify a consensus Capability Framework for Diabetes Care (the 'Framework'). An implementation phase followed, involving representation from people with diabetes and key health professional organisations to co-design and implement the 'Framework'. The 'Framework' can guide curricula at universities and TAFE institutes, and the professional development and practice of Australian nurses, allied health professionals, First Nations Australians health workers and practitioners, pharmacists, midwives and health assistants when delivering care to people living with diabetes. The 'Framework' defines nine core capabilities that healthcare providers require to deliver diabetes care effectively, underpinned by three sets of attributes for seven practice levels to enable the workforce. Information within the practice levels provides a nationally consistent approach to learning and training different healthcare providers in the essential elements of diabetes care. A 'living' evidence-based national 'Framework' for the whole health workforce and associated online resources will help promote a more responsive health workforce delivering better and more equitable diabetes care.

Prevalence and incidence of diabetes among Aboriginal people in remote communities of the Northern Territory, Australia: a retrospective, longitudinal data-linkage study

OBJECTIVES

To assess the prevalence and incidence of diabetes among Aboriginal peoples in remote communities of the Northern Territory (NT), Australia.

DESIGN

Retrospective cohort analysis of linked clinical and administrative data sets from 1 July 2012 to 30 June 2019.

SETTING

Remote health centres using the NT Government Primary Care Information System (51 out of a total of 84 remote health centres in the NT).

PARTICIPANTS

All Aboriginal clients residing in remote communities serviced by these health centres (N=21 267).

PRIMARY OUTCOME MEASURES

Diabetes diagnoses were established using hospital and primary care coding, biochemistry and prescription data.

RESULTS

Diabetes prevalence across all ages increased from 14.4% (95% CI: 13.9% to 14.9%) to 17.0% (95% CI: 16.5% to 17.5%) over 7 years. Among adults (≥20 years), the 2018/2019 diabetes prevalence was 28.6% (95% CI: 27.8% to 29.4%), being higher in Central Australia (39.5%, 95% CI: 37.8% to 41.1%) compared with the Top End region (24.2%, 95% CI: 23.3% to 25.1%, p<0.001). Between 2016/2017 and 2018/2019, diabetes incidence across all ages was 7.9 per 1000 person-years (95% CI: 7.3 to 8.7 per 1000 person-years). The adult incidence of diabetes was 12.6 per 1000 person-years (95% CI: 11.5 to 13.8 per 1000 person-years).

CONCLUSIONS

The burden of diabetes in the remote Aboriginal population of the NT is among the highest in the world. Strengthened systems of care and public health prevention strategies, developed in partnership with Aboriginal communities, are needed.

"I Don't Really Know What Diabetes Is": A Qualitative Study Exploring the Experiences of Aboriginal and Torres Strait Islander Young People Aged 10 to 25 Years Living With Type 2 Diabetes in Northern and Central Australia

OBJECTIVE

Our aim in this study was to gain an understanding of the experiences of Aboriginal and Torres Strait Islander young people aged 10 to 25 years with type 2 diabetes (T2D) living in Northern and Central Australia.

METHODS

In this qualitative study we explored participants' experiences of T2D using a social constructionist epistemology and a phenomenologic methodology. Twenty-seven young people participated in semistructured in-depth interviews from 4 primary health-care sites.

RESULTS

Three major constructs emerged. Young people experienced a normalisation-shame paradox in response to their diagnosis (partly related to that "everyone has diabetes," as well as the fear that friends "might judge [me]"), had suboptimal levels of understanding of T2D ("I don't really know what diabetes is. I just need somebody to explain to me a bit more") and experienced multiple barriers inhibiting their T2D management. These included complex lives ("I have a rheumatic heart disease […] then they told me that I have diabetes…I have two things") and the availability of support ("[I] talk to my mum…I talk to my aunty too…I don't talk to anyone else"). Successful management requires support from health professionals and family and includes strengthening social networks and educational opportunities.

CONCLUSIONS

Our findings reinforce the need for alternative support systems tailored to the specific needs of young Aboriginal and Torres Strait Islander people with T2D. Enhanced models of care must be codesigned with young people and their communities and include a focus on shifting norms and expectations about youth T2D to reduce diabetes stigma and broaden social support and consider the delivery of health information in youth-friendly environments.

A mixed-methods evaluation of an urban Aboriginal diabetes lifestyle program

OBJECTIVE

The objective of this study was to evaluate an Aboriginal-led diabetes lifestyle program catering to urban Aboriginal people in an Aboriginal organisation.

METHODS

Mixed-methods study that employed routinely collected physiological data and audio-recorded focus group sessions. Physiological data were analysed using a multi-level model to account for participant clustering. Qualitative data were subject to thematic analysis.

RESULTS

Participants were overwhelmingly positive about the program. They lost weight and improved their diastolic blood pressure and glycaemic control; however, it was the feelings of belonging and optimism about their ability to improve their health that they most valued. Qualitative analysis revealed three main themes. These were: 'With the Mob', 'For the Mob' and 'Program Elements. The strengths of the program lay in its indigeneity, low-cost and easy-to-prepare diet, and cultural and communication skills of the director.

CONCLUSIONS

Recommendations for improvement included educating participants on the pathophysiology of diabetes, the refinement of online elements and the introduction of face-to-face group exercise. Implications for public health: Programs of this nature should be expanded and evaluated longitudinally with multiple cohorts.

Diabetes during pregnancy and birthweight trends among Aboriginal and non-Aboriginal people in the Northern Territory of Australia over 30 years

Background

Early-life risk factors, including maternal hyperglycaemia and birthweight, are thought to contribute to the high burden of cardiometabolic disease experienced by Indigenous populations. We examined rates of pre-existing diabetes in pregnancy, gestational diabetes mellitus (GDM) and extremes of birthweight over three decades in the Northern Territory (NT) of Australia.

Methods

We performed a retrospective cohort analysis of the NT Perinatal Data Collection from 1987 to 2016, including all births >20 weeks gestation, stratified by maternal Aboriginal identification. Key outcomes were annual rates of pre-existing diabetes, GDM, small-for-gestational-age, large-for-gestational-age, low birthweight (<2500 g), and high birthweight (>4000 g). Logistic regression was used to assess trends and interactions.

Findings

109 349 babies were born to 64 877 mothers, 36% of whom identified as Aboriginal ethnicity. Among Aboriginal women, rates of GDM and pre-existing diabetes, respectively, were 3 · 4% and 0 · 6% in 1987 and rose to 13% and 5 · 7% in 2016 (both trends p<0 · 001). Among non-Aboriginal women, rates of GDM increased from 1 · 9% in 1987 to 11% in 2016 (p<0 · 001), while pre-existing diabetes was uncommon (≤0 · 7% throughout). Rates of small-for-gestational-age decreased, while rates of large-for-gestational-age and high birthweight increased in both groups (all trends p<0 · 001). Multivariable modelling suggests that hyperglycaemia was largely responsible for the growing rate of large-for-gestational-age births among Aboriginal women.

Interpretation

The burden of hyperglycaemia in pregnancy has grown substantially in the NT over three decades and is impacting birthweight trends. The prevalence of pre-gestational diabetes in Aboriginal women is among the highest in the world.
