Looking after bubba for all our mob: Aboriginal and Torres Strait Islander community experiences and perceptions of stillbirth.

The stillbirth rate among Aboriginal and Torres Strait Islander women and communities in Australia is around double that of non-Indigenous women. While the development of effective prevention strategies during pregnancy and improving care following stillbirth for women and families in communities has become a national priority, there has been limited progress in stillbirth disparities. With community permission, this study aimed to gain a better understanding of community experiences, perceptions, and priorities around stillbirth. We undertook an Indigenous researcher-led, qualitative study, with community consultations guided by a cultural protection protocol and within an unstructured research framework. A total of 18 communities were consulted face-to-face through yarning interviews, focus groups and workshops. This included 54 community member and 159 health professional participants across remote, regional, and urban areas of Queensland, Western Australia, Victoria, South Australia, and Northern Territory. Thematic analysis of consultation data identified common themes across five focus/priority areas to address stillbirth: Stillbirth or Sorry Business Baby care needs to be family-centered; using Indigenous "ways of knowing, being, and doing" to ensure cultural safety; application of Birthing on Country principles to maternal and perinatal care; and yarning approaches to improve communication and learning or education. The results underscore the critical need to co-design evidence-based, culturally appropriate, and community-acceptable resources to help reduce existing disparities in stillbirth rates.

First Nations Peoples' perceptions, knowledge and beliefs regarding stillbirth prevention and bereavement practices: A mixed methods systematic review.

BACKGROUND: First Nations Peoples endure disproportionate rates of stillbirth compared with non-First Nations Peoples. Previous interventions have aimed at reducing stillbirth in First Nations Peoples and providing better bereavement care without necessarily understanding the perceptions, knowledge and beliefs that could influence the design of the intervention and implementation. AIM: The aim of this review was to understand the perceptions, knowledge and beliefs about stillbirth prevention and bereavement of First Nations Peoples from the US, Canada, Aotearoa/New Zealand, and Australia. METHODS: This review was conducted in accordance with the JBI methodology for a convergent integrated mixed method systematic review. This review was overseen by an advisory board of Aboriginal Elders, researchers, and clinicians. A search of eight databases (PubMed, MEDLINE, PsycInfo, CINAHL, Embase, Emcare, Dissertations and Theses and Indigenous Health InfoNet) and grey literature was conducted. All studies were screened, extracted, and appraised for quality by two reviewers and results were categorised, and narratively summarised. RESULTS: Ten studies were included within this review. Their findings were summarised into four categories: safeguarding baby, traditional practices of birthing and grieving, bereavement photography and post-mortem examination. The results indicate a diversity of perceptions, knowledge and beliefs primarily around smoking cessation and bereavement practices after stillbirth. However, there was a paucity of research available. CONCLUSIONS: Further research is needed to understand the perceptions, knowledge and beliefs about stillbirth among First Nations Peoples. Without research within this area, interventions to prevent stillbirth and support bereaved parents and their communities after stillbirth may face barriers to implementation.

Development and Functionality of a Parsimonious Digital Food Frequency Questionnaire for a Clinical Intervention among an Indigenous Population.

Nutrition-related chronic diseases are a major problem among Indigenous populations. Appropriate dietary intake assessment tools are needed for nutritional surveillance and intervention; however, tools designed to measure the habitual dietary intake of Indigenous persons are largely lacking. We developed a digital food frequency questionnaire (FFQ) to measure habitual consumption among Australian Aboriginal adults and support personalized nutrition counseling. The primary contributors to energy, select nutrients, and inter-person variation (83 food groups) were identified from nationally representative 24 h recall (24HR) data, and they accounted for >80% of the total intake and inter-person variation of the nutrients of interest. Based on community input, a meal-based FFQ format was adopted, with a main food/beverage list of 81 items and the capacity to report on >300 additional items via the digital platform. The nutrient database was based on the Australian Food and Nutrient Database. Data for the first 60 study participants (70% female; median age: 48 years) were used to assess the FFQ's utility. The participants' median [IQR] reported energy intake (10,042 [6968-12,175] kJ/day) was similar to their median [IQR] estimated energy expenditure (10,197 [8636-11,551] kJ/day). Foods/beverages on the main FFQ list accounted for between 66% and 90% of the participants' reported energy and nutrient intakes; the remainder came from participant-selected extra items. The digital FFQ platform provides a potentially valuable resource for monitoring habitual dietary intake among Aboriginal adults and supporting chronic disease prevention and management interventions.

Mapping the citation network on vitamin D research in Australia: a data-driven approach.

Vitamin D research can vary geographically, as vitamin D status is influenced by latitude, season, dietary intake, body mass index, ethnicity, and public health initiatives. Over the last two decades, research on vitamin D has increased in Australia, where the potential for sun exposure (a major source of vitamin D) is high. We aimed to identify key topics and gaps in vitamin D research in Australia using a data-driven approach. A literature search limited to Australian studies was conducted in the Web of Science Core Collection database. Citation network analysis was conducted to identify clusters and sub-clusters, depicted using word clouds. Topic analysis of each cluster and sub-cluster was conducted to identify topics and sub-topics, respectively. From 934 publications (over the period 1984-2022), nine topics and 60 sub-topics were identified. The nine topics were: vitamin D in vulnerable populations and its impact on child development; impact of sun exposure and ultraviolet-B radiation on various health conditions; vitamin D and falls and fractures in older adults; vitamin D and its association with health outcomes; vitamin D from sun exposure; testing of vitamin D status in Australia; vitamin D, calcium, and musculoskeletal health; vitamin D status and knee osteoarthritis; and vitamin D status and exercise performance in athletes. There were limited publications on vitamin D in Aboriginal and Torres Strait Islander peoples and dietary vitamin D. We have provided an overview of vitamin D research in Australia. The research trends and knowledge gaps identified can guide future research to better inform public health initiatives in Australia.

Hospital and emergency department discharge against medical advice in Western Australian Aboriginal children aged 0-4 years from 2002 to 2018: A cohort study.

BACKGROUND: Discharge against medical advice (DAMA) is a priority issue for the health system. Little is known about the factors associated with DAMA for Aboriginal and/or Torres Strait Islander (Aboriginal) children in Australia. OBJECTIVES: Investigate the associations between DAMA for hospital admissions and emergency department (ED) presentations and: (i) child, family and episode of service characteristics and (ii) 30-day readmission/ re-presentation. METHODS: We conducted a cohort study of Aboriginal children born in Western Australia (2002-2013) who had ≥1 hospital admissions (n = 16,931) or ED presentations (n = 26,546) within the first 5 years of life. The outcome of interest was hospital and ED DAMA and adjusted odds ratio were derived using multilevel mixed-effects logistic regression. RESULTS: In the Hospital Cohort, there were 43,149 hospitalisations for 16,931 children, with 684 hospitalisations (1.6%) recorded as DAMA. In the ED Cohort, there were 232,082 ED presentations in 26,546 children, with 10,918 ED presentations (4.7%) recorded as DAMA. DAMA occurring in hospitals between 2014 and 2018, the adjusted odds decreased by 75% compared to the period between 2002 and 2005. The adjusted odds of ED DAMA increased by 46% over the same period. Hospital admissions in regional and remote hospitals were almost seven times the adjusted odds of DAMA compared with hospital admissions in Perth metropolitan hospitals. The adjusted odds of ED DAMA decreased by 12% for ED presentations in regional and remote hospitals compared to those in Perth metropolitan hospitals. There was no evidence of hospital DAMA being associated with hospital readmission within 30 days and limited evidence of ED DAMA being associated with re-presenting to an ED within 30 days. CONCLUSIONS: The study identified several important determinants of DAMA, including admission status, triage status, location and calendar year. These findings could inform targeted measures to decrease DAMA, particularly in regional and remote communities.

Overweight/obesity and other predictors of gestational diabetes among Aboriginal and non-Aboriginal women in Western Australia.

This population-based study investigated the association of BMI and other predictors with gestational diabetes mellitus (GDM) among Australian Aboriginal and non-Aboriginal mothers. We conducted a state-wide retrospective cohort study that included all singleton births in Western Australia (n = 134,552) between 2012 and 2015 using population health datasets linked by the Western Australian Data Linkage Branch. Associations between GDM and its predictors were estimated as adjusted relative risks (aRRs) from multivariable generalised linear models. Adjusted ratio of relative risks (aRRRs) compared RRs in Aboriginal and non-Aboriginal mothers. Adjusted population attributable fractions estimated the contribution of overweight/obesity to GDM burden, and adjusted predicted probabilities for GDM were plotted against BMI levels. The following predictors had stronger associations with GDM in Aboriginal, compared to non-Aboriginal, mothers: maternal obesity (aRR [95% CI] 3.16 [2.54-3.93]; aRRR 1.57 [1.26-1.94]), previous LGA (aRR 1.70 [1.37-2.12]; aRRR 1.41 [1.13-1.76]) and previous macrosomia (birthweight ≥ 4 kg) (aRR 1.55 [1.24-1.94]; aRRR 1.53 [1.22-1.91]). 46.1% (95% CI: 36.6-54.1) of GDM cases in Aboriginal women (23.3% in non-Aboriginal mothers, 95% CI: 21.6-25.1) were attributed to overweight/obesity. Compared to non-Aboriginal mothers, adjusted GDM probabilities were higher at all BMI levels and showed greater increase with BMI. Overweight/obesity is a key driver of GDM among Aboriginal women. Association between BMI and GDM is stronger in Aboriginal, compared to non-Aboriginal, women especially at higher BMI.

First Nations populations' perceptions, knowledge, attitudes, beliefs, and myths about prevention and bereavement in stillbirth: a mixed methods systematic review protocol.

OBJECTIVE: The objective of this review is to investigate First Nations populations' perceptions, knowledge, attitudes, beliefs, and myths about stillbirth. INTRODUCTION: First Nations populations experience disproportionate rates of stillbirth compared with non-First Nations populations. There has been a surge of interventions aimed at reducing stillbirth and providing better bereavement care, but these are not necessarily appropriate for First Nations populations. As a first step toward developing appropriate interventions for these populations, this review will examine current perceptions, knowledge, attitudes, beliefs, and myths about stillbirth held by First Nations people from the United States, Canada, Aotearoa/New Zealand, and Australia. INCLUSION CRITERIA: The review will consider studies that include individuals of any age (bereaved or non-bereaved) who identify as belonging to First Nations populations. Eligible studies will include the perceptions, knowledge, attitudes, beliefs, and myths about stillbirth among First Nations populations. METHODS: This review will follow the JBI methodology for convergent mixed methods systematic reviews. The review is supported by an advisory panel of Aboriginal elders, lived-experience stillbirth researchers, Aboriginal researchers, and clinicians. PubMed, MEDLINE (Ovid), CINAHL (EBSCOhost), Embase (Ovid), Emcare (Ovid), PsycINFO (EBSCOhost), Indigenous Health InfoNet, Trove, Informit, and ProQuest Dissertations and Theses will be searched for relevant information. Titles and abstracts of potential studies will be screened and examined for eligibility. After critical appraisal, quantitative and qualitative data will be extracted from included studies, with the former "qualitized" and the data undergoing a convergent integrated approach. REVIEW REGISTRATION: PROSPERO CRD42023379627.

The perinatal and childhood outcomes of children born to Indigenous women with mental health problems: A scoping review.

OBJECTIVE: Maternal mental health problems are common during the perinatal period and have been associated with several negative outcomes in children. However, few studies have examined the associations between maternal mental health problems and offspring outcomes among Indigenous people, and the findings across these studies have been inconsistent. This scoping review examined the birth and childhood (≤12 years) health and development outcomes of the children of Indigenous women with mental health problems. METHODS: A scoping review was conducted following the methodological framework developed by Arksey and O'Malley and based on the PRISMA-ScR guidelines. Eight databases were searched electronically for studies examining the associations between any perinatal maternal mental health problems and birth and childhood outcomes among the Indigenous populations of Australia, Canada, New Zealand, and the USA. Two authors reviewed studies for inclusion. A narrative synthesis approach was adopted. RESULTS: Of 2,836 records identified, 10 were eligible. One of three studies evaluating maternal depression and anxiety problems found a negative (adverse) association with birth and childhood behavioural outcomes. Six of seven studies that examined the associations between maternal substance use disorder (mainly alcohol use disorder) and several birth and childhood outcomes found at least one negative association. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Maternal substance use disorder appears to be associated with adverse birth and childhood outcomes among some Indigenous populations. However, there is preliminary evidence for the other common maternal mental health problems. Further research is critically required to draw definitive conclusions regarding the impact of maternal mental health problems on the birth and childhood outcomes.

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.

Perinatal outcomes of Aboriginal women with mental health disorders.

OBJECTIVE: Maternal mental disorders have been associated with adverse perinatal outcomes such as low birthweight and preterm birth, although these links have been examined rarely among Australian Aboriginal populations. We aimed to evaluate the association between maternal mental disorders and adverse perinatal outcomes among Aboriginal births. METHODS: We used whole population-based linked data to conduct a retrospective cohort study (N = 38,592) using all Western Australia singleton Aboriginal births (1990-2015). Maternal mental disorders were identified based on the International Classification of Diseases diagnoses and grouped into six broad diagnostic categories. The perinatal outcomes evaluated were preterm birth, small for gestational age, perinatal death, major congenital anomalies, foetal distress, low birthweight and 5-minute Apgar score. We employed log-binomial/-Poisson models to calculate risk ratios and 95% confidence intervals. RESULTS: After adjustment for sociodemographic factors and pre-existing medical conditions, having a maternal mental disorder in the five years before the birth was associated with adverse perinatal outcomes, with risk ratios (95% confidence intervals) ranging from 1.26 [1.17, 1.36] for foetal distress to 2.00 [1.87, 2.15] for low birthweight. We found similar associations for each maternal mental illness category and neonatal outcomes, with slightly stronger associations when maternal mental illnesses were reported within 1 year rather than 5 years before birth and for substance use disorder. CONCLUSIONS: This large population-based study demonstrated an increased risk of several adverse birth outcomes among Aboriginal women with mental disorders. Holistic perinatal care, treatment and support for women with mental disorders may reduce the burden of adverse birth outcomes.

Early mortality among aboriginal and non-aboriginal women who had a preterm birth in Western Australia: A population-based cohort study.

BACKGROUND: Having a preterm (<37 weeks' gestation) birth may increase a woman's risk of early mortality. Aboriginal and Torres Strait Islander (hereafter Aboriginal) women have higher preterm birth and mortality rates compared with other Australian women. OBJECTIVES: We investigated whether a history of having a preterm birth was associated with early mortality in women and whether these associations differed by Aboriginal status. METHODS: This retrospective cohort study used population-based perinatal records of women who had a singleton birth between 1980 and 2015 in Western Australia linked to Death Registry data until June 2018. The primary and secondary outcomes were all-cause and cause-specific mortality respectively. After stratification by Aboriginal status, rate differences were calculated, and Cox proportional hazard regression was used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and cause-specific mortality. RESULTS: There were 20,244 Aboriginal mothers (1349 deaths) and 457,357 non-Aboriginal mothers (7646 deaths) with 8.6 million person-years of follow-up. The all-cause mortality rates for Aboriginal mothers who had preterm births and term births were 529.5 and 344.0 (rate difference 185.5, 95% CI 135.5, 238.5) per 100,000 person-years respectively. Among non-Aboriginal mothers, the corresponding figures were 125.5 and 88.6 (rate difference 37.0, 95% CI 29.4, 44.9) per 100,000 person-years. The HR for all-cause mortality for Aboriginal and non-Aboriginal mothers associated with preterm birth were 1.48 (95% CI 1.32, 1.66) and 1.35 (95% CI 1.26, 1.44), respectively, compared with term birth. Compared with mothers who had term births, mothers of preterm births had higher relative risks of mortality from diabetes, cardiovascular, digestive and external causes. CONCLUSIONS: Both Aboriginal and non-Aboriginal women who had a preterm birth had a moderately increased risk of mortality up to 38 years after the birth, reinforcing the importance of primary prevention and ongoing screening.

Severe maternal morbidity following stillbirth in Western Australia 2000-2015: a population-based study.

PURPOSE: There is scant literature about the management of stillbirth and the subsequent risk of severe maternal morbidity (SMM). We aimed to assess the risk of SMM associated with stillbirths compared with live births and whether this differed by the presence of maternal comorbidities. METHODS: In this retrospective cohort study, we used a population-based dataset of all stillbirths and live births ≥ 20 weeks' gestation in Western Australia between 2000 and 2015. SMM was identified using a published Australian composite for use with routinely collected hospital morbidity data. Maternal comorbidities were identified in the Hospital Morbidity Data Collection or the Midwives Notification System using a modified Australian chronic disease composite. Multivariable Poisson regression was used to estimate relative risks (RRs) and 95% confidence intervals (CIs) for factors associated with SMM in analyses stratified by the presence of maternal comorbidities. Singleton and multiple pregnancies were examined separately. RESULTS: This study included 458,639 singleton births (2319 stillbirths and 456,320 live births). The adjusted RRs for SMM among stillbirths were 2.30 (95% CI 1.77, 3.00) for those without comorbidities and 4.80 (95% CI 4.11, 5.59) (Interaction P value < 0.0001) for those with comorbidities compared to live births without and with comorbidities, respectively. CONCLUSION: In Western Australia between 2000 and 2015, mothers of stillbirths both with and without any maternal comorbidities had an increased risk of SMM compared with live births. Further investigation into why women who have had a stillbirth without any existing conditions or pregnancy complications develop SMM is warranted.

Vitamin D composition of Australian game products.

The vitamin D content of many Australian game products is unknown. These foods are potential sources of vitamin D for remote-dwelling Aboriginal and Torres Strait Islander people, of whom 39% are vitamin D deficient (serum 25-hydroxyvitamin D3 (25(OH)D3) concentrations < 50 nmol/L). Vitamin D3, 25(OH)D3, vitamin D2 and 25(OH)D2 were measured by liquid chromatography-triple quadrupole mass spectrometry (LC-QQQ) in raw meat (camel, crocodile, emu, kangaroo), emu eggs and emu oil. Vitamin D3 (range, 0.5-14.5 µg/100 g) was found in all products except camel and kangaroo. All samples except kangaroo contained 25(OH)D3; some camel samples contained relatively high concentrations (range, 0.4-5.2 µg/100 g). Vitamin D2 was found in emu products and some kangaroo samples. We detected trace amounts of 25(OH)D2 in some camel and kangaroo samples. This study provides valuable insight into foods with a paucity of data on vitamin D content, showing that some are potentially useful sources of vitamin D.

Patterns of recurrent preterm birth in Western Australia: A 36-year state-wide population-based study.

BACKGROUND: It is known that a previous preterm birth increases the risk of a subsequent preterm birth, but a limited number of studies have examined this beyond two consecutive pregnancies. AIMS: This study aimed to assess the risk and patterns of (recurrent) preterm birth up to the fourth pregnancy. MATERIALS AND METHODS: We used Western Australian routinely linked population health datasets to identify women who had two or more consecutive singleton births (≥20 weeks gestation) from 1980 to 2015. A log-binomial model was used to calculate risk ratios (RRs) and 95% confidence interval (CIs) for preterm birth risk in the third and fourth deliveries by the combined outcomes of previous pregnancies. RESULTS: We analysed 255 435 women with 651 726 births. About 7% of women had a preterm birth in the first delivery, and the rate of continuous preterm birth recurrence was 22.9% (second), 44.9% (third) and 58.5% (fourth) deliveries. The risk of preterm birth at the third delivery was highest for women with two prior indicated preterm births (RR 12.5, 95% CI: 11.3, 13.9) and for those whose first pregnancy was 32-36 weeks gestation, and second pregnancy was less than 32 weeks gestation (RR 11.8, 95% CI: 10.3, 13.5). There were similar findings for the second and fourth deliveries. CONCLUSIONS: Our findings demonstrate that women with any prior preterm birth were at greater risk of preterm birth in subsequent pregnancies compared with women with only term births, and the risk increased with shorter gestational length, and the number of previous preterm deliveries, especially sequential ones.

Trends and burden of diabetes in pregnancy among Aboriginal and non-Aboriginal mothers in Western Australia, 1998-2015.

BACKGROUND: Diabetes in pregnancy (DIP), which includes pre-gestational and gestational diabetes, is more prevalent among Aboriginal women. DIP and its adverse neonatal outcomes are associated with diabetes and cardiovascular disease in the offspring. This study investigated the impact of DIP on trends of large for gestational age (LGA) in Aboriginal and non-Aboriginal populations, and added to the limited evidence on temporal trends of DIP burden in these populations. METHODS: We conducted a retrospective cohort study that included all births in Western Australia between 1998 and 2015 using linked population health datasets. Time trends of age-standardised and crude rates of pre-gestational and gestational diabetes were estimated in Aboriginal and non-Aboriginal mothers. Mixed-effects multivariable logistic regression was used to estimate the association between DIP and population LGA trends over time. RESULTS: Over the study period, there were 526,319 births in Western Australia, of which 6.4% were to Aboriginal mothers. The age-standardised annual rates of pre-gestational diabetes among Aboriginal mothers rose from 4.3% in 1998 to 5.4% in 2015 and remained below 1% in non-Aboriginal women. The comparable rates for gestational diabetes increased from 6.7 to 11.5% over the study period in Aboriginal women, and from 3.5 to 10.2% among non-Aboriginal mothers. LGA rates in Aboriginal babies remained high with inconsistent and no improvement in pregnancies complicated by gestational diabetes and pre-gestational diabetes, respectively. Regression analyses showed that DIP explained a large part of the increasing LGA rates over time in Aboriginal babies. CONCLUSIONS: There has been a substantial increase in the burden of pre-gestational diabetes (Aboriginal women) and gestational diabetes (Aboriginal and non-Aboriginal) in recent decades. DIP appears to substantially contribute to increasing trends in LGA among Aboriginal babies.

Caesarean section following antepartum stillbirth in Western Australia 2010-2015: A population-based study.

BACKGROUND: There is scant literature about antepartum stillbirth management but guidelines usually recommend reserving caesarean sections for exceptional circumstances. However, little is known about caesarean section rates following antepartum stillbirth in Australia. AIMS: We aimed to describe the onset of labour, mode of birth, and use of analgesia and anaesthesia following antepartum stillbirth and to identify factors associated with caesarean section. MATERIAL AND METHODS: In this retrospective cohort study, we used a population-based dataset of all singleton antepartum stillbirths ≥20 weeks gestation in Western Australia between 2010-2015. The overall, primary and repeat caesarean section rates for antepartum stillbirths were calculated and multivariable Poisson regression analyses were performed to identify associated factors, and to calculate relative risks (RRs) and 95% confidence intervals (CIs). RESULTS: This study included 634 antepartum stillbirths. Labour was spontaneous for 134 (21.1%), induced for 457 (72.1%), and 43 (6.8%) had a prelabour caesarean section. The overall, primary and repeat caesarean section rates were 8.5%, 4.6% and 23.0% respectively and increased with gestation (P trends all <0.01). Other factors associated with an increased caesarean section risk included: any placenta praevia or placental abruption, birth at a metropolitan private hospital, large-for-gestational-age birthweight, and any maternal chronic condition. During labour, the most frequently used types of analgesia were systemic narcotics (46.0%) and regional blocks (34.7%) while among those who had a caesarean section, 40.7% had a general anaesthetic. CONCLUSIONS: In Western Australia between 2010-2015, the caesarean section rates among women with antepartum stillbirths were low, in line with current guidelines.

Measuring Social and Emotional Wellbeing in Aboriginal Youth Using Strong Souls: A Rasch Measurement Approach.

Currently, there are few robustly evaluated social and emotional wellbeing (SEWB) measures available for use with Aboriginal youth in research, policy, and practice. As such, this study used a Rasch measurement approach to examine the psychometric properties of Strong Souls, a 25-item self-reported SEWB instrument, created for use with Aboriginal youth in the Northern Territory. Our sample (N = 154) included youth (15-25 years old) living on Whadjuk (metropolitan Western Australia; N = 91) and Kamilaroi countries (rural New South Wales; N = 63). Using Rasch modelling techniques, evidence for multidimensionality in the scale was observed, resulting in subsequent analyses conducted separately on two subscales: Psychological Distress and Resilience. The Resilience subscale did not meet the Rasch model assumptions, with poor person and item separation and reliability indexes suggesting the scale was not reliably differentiating between participants' Resilience scores. The Psychological Distress subscale had mixed separation and reliability index results, with good construct validity implied but poorer ability to target the distress of participants. Our findings provide novel evidence demonstrating the functioning of Strong Souls in a contemporary sample of Aboriginal youth, suggesting further modifications of the instrument are required before it can be used with confidence as a reliable measure in this population group.

Disparities in severe neonatal morbidity and mortality between Aboriginal and non-Aboriginal births in Western Australia: a decomposition analysis.

BACKGROUND: The health disadvantages faced by Australian Aboriginal peoples are evidenced in early life, although few studies have focused on the reasons for population-level inequalities in more severe adverse outcomes. This study aimed to examine the scale of disparity in severe neonatal morbidity (SNM) and mortality between Aboriginal and non-Aboriginal births and quantify the relative contributions of important maternal and infant factors. METHOD: A retrospective cohort study with singleton live births (≥32 weeks' gestation) was conducted using Western Australia linked whole population datasets, from 1999 to 2015. Aboriginal status was determined based on the mothers' self-reported ethnic origin. An Australian validated indicator was adapted to identify neonates with SNM. The Oaxaca-Blinder method was employed to calculate the contribution of each maternal and infant factor to the disparity in SNM and mortality. RESULTS: Analyses included 425 070 births, with 15 967 (3.8%) SNM and mortality cases. The disparity in SNM and mortality between Aboriginal and non-Aboriginal births was 2.9 percentage points (95% CI 2.6 to 3.2). About 71% of this gap was explained by differences in modelled factors including maternal area of residence (23.8%), gestational age (22.2%), maternal age (7.5%) and antenatal smoking (7.2%). CONCLUSIONS: There is a considerable disparity in SNM and mortality between Aboriginal and non-Aboriginal births in Western Australia with the majority of this related to differences in maternal sociodemographic factors, antenatal smoking and gestational age. Public health programmes targeting these factors may contribute to a reduction in early life health differentials and benefit Aboriginal population health through the life course.

Connection to... Addressing Digital Inequities in Supporting the Well-Being of Young Indigenous Australians in the Wake of COVID-19.

(1) Background: This article examines whether connection to digital technologies helps connect young Indigenous people in Australia to culture, community and country to support good mental health and well-being and protect against indirect and potentially long-term effects of COVID-19. (2) Method: We reviewed literature published between February and November 2020 and policy responses related to digital strategies. We searched PubMed, Google Scholar, government policy websites and key Indigenous literature sources, identifying 3460 articles. Of these, 30 articles and 26 policy documents were included and analysed to identify existing and expected mental health outcomes among Indigenous young people associated with COVID-19 and more broadly. (3) Results: There are inequities in affordable access to digital technologies. Only 63% of Indigenous people have access to internet at home. Digital technologies and social media contribute to strong cultural identity, enhance connections to community and country and improve mental health and social and emotional well-being outcomes. (4) Discussion: Access to digital technologies can facilitate healing and cultural continuity, self-determination and empowerment for young people to thrive, not just survive, in the future. (5) Conclusion: More targeted policies and funding is urgently needed to promote digital technologies to enhance Indigenous young people's access to mental health and well-being services, maintain cultural connections and evaluate the effectiveness of these initiatives using Indigenous well-being indicators.

Comparison of stillbirth trends over two decades in Wales, United Kingdom and Western Australia: An international retrospective cohort study.

BACKGROUND: Stillbirth is a critical public health issue worldwide. While the rates in high-income countries are relatively low, there are persistent between-country disparities. OBJECTIVES: To compare stillbirth rates and trends in Wales and the State of Western Australia (WA), Australia, and provide insights into any differences. METHODS: In this international retrospective cohort study, we pooled population-based data collections of all births ≥24 weeks' gestation (excluding terminations for congenital anomalies) between 1993 and 2015, divided into six time periods. The stillbirth rate per 1000 births was estimated for each cohort in each time period. Multivariable Poisson regression analyses, adjusted for appropriateness of growth, socio-economic status, maternal age, and multiple birth, were performed to evaluate the interaction between cohort and time period. Relative risk (RR) and 95% confidence interval (CI) for each time period and cohort were calculated. RESULTS: There were 767 731 births (3725 stillbirths) in Wales and 648 373 (2431 stillbirths) in WA. The overall stillbirth rate declined by 15.9% over the study period in Wales (from 5.3 in 1993-96 to 4.5 per 1000 births in 2013-15; Ptrend  < .01) but by 40.4% in WA (from 4.9 to 2.9 per 1000 births in WA; Ptrend  < .01). Using 1993-96 in WA as the reference group, the adjusted RRs for stillbirths at 37-38 weeks' gestation in the most recent study period (2013-15) were 0.85 (95% CI 0.64, 1.13) in Wales and 0.51 (95% CI 0.36, 0.73) in WA. CONCLUSIONS: The stillbirth rates between Wales and WA have widened in the last two decades (especially among late-term births), although the absolute rates for both are distinctly higher than the best-performing nations. While the differences may be partly explained by timing of birth and maternal life style behaviours such as smoking, it is important to identify and ameliorate the associated risk factors to support a reduction in preventable stillbirths.
