Dietary Intake and Anthropometric Measurement at Age 36 Months Among Aboriginal and/or Torres Strait Islander Children in Australia: A Secondary Analysis of the Baby Teeth Talk Randomized Clinical Trial.

Importance: Interventions to reduce early childhood caries should be examined for their effects on anthropometry given their design to improve children's diets. Objective: To compare the outcomes of dietary intake, anthropometric measurements, and blood pressure measurements between children at age 36 months in the immediate intervention group vs those in the delayed intervention group. Design, Setting, and Participants: This secondary analysis was a follow-up to the 2-group Baby Teeth Talk randomized clinical trial conducted across the state of South Australia, Australia. Participants were Aboriginal and/or Torres Strait Islander children and their caregivers who were randomized to the immediate intervention group or delayed intervention group. The intervention was provided from February 1, 2011, to May 31, 2012. The prespecified follow-up when the participating children were aged 36 months was conducted from November 1, 2014, to February 28, 2016, in participant homes or public locations. Data were analyzed from October 5, 2018, to April 29, 2019. Interventions: The immediate intervention group received the intervention during pregnancy and at 6, 12, and 18 months of age. The delayed intervention group received the intervention at 24, 30, and 36 months of age. Both groups received an intervention consisting of free dental care for mothers, fluoride varnish on children's teeth, anticipatory guidance on oral health and dietary advice, and motivational interviewing. Main Outcomes and Measures: Dietary intake was measured with a caregiver-completed, 17-item food frequency questionnaire. Frequency of consumption of discretionary foods and beverages were the main dietary outcomes. Children's weight, height, and mid-upper arm circumference were measured and converted to age- and sex-specific z scores. Body mass index z score was the main anthropometric outcome. Results: A total of 330 children were followed up to age 36 months among the 448 mothers and 454 children who were randomized to the 2 groups. At baseline, the women had a mean (SD) age of 24.9 (5.9) years, and the children had a mean (SD) weight of 3.3 (0.6) kilograms at birth, and 205 were boys (46%); sex was not recorded for 63 children (14%). Diet outcomes were similar between the groups. For example, the mean (SD) intake of discretionary beverages by the immediate intervention group was similar to that by the delayed intervention group (507 [536] mL/d vs 520 [546] mL/d; adjusted mean difference [MD], -16 [95% CI, -133 to 102] mL/d; P = .79). Height was similar between the 2 groups, but the mean (SD) z scores of weight (0.7 [1.0] vs 0.4 [1.0]; adjusted MD, 0.3 [95% CI, 0.1-0.5]; P = .02), arm circumference (1.6 [1.0] vs 1.3 [0.9]; adjusted MD, 0.2 [95% CI, 0.1-0.5]; P = .03), and body mass index (1.1 [1.1] vs 0.9 [0.9]; adjusted MD, 0.2 [95% CI, 0.0-0.4]; P = .04) were higher in the immediate intervention group than the delayed intervention group. Conclusions and Relevance: This study found no differences in dietary intakes between children who received an intervention to reduce dental caries early and those who received it later. At age 36 months, children in the immediate intervention group had greater z scores for weight, arm circumference, and body mass index than their counterparts in the delayed intervention group, suggesting a potential implication of oral health interventions for anthropometric outcomes.

Clinical and histological features of immune-mediated necrotising myopathy: A multi-centre South Australian cohort study.

Immune-mediated necrotising myopathy (IMNM) is a recently described entity. We describe a cohort of South Australian IMNM patients in order to define the spectrum of disease, characterise features that distinguish IMNM from other idiopathic inflammatory myopathy (IIM) subtypes and identify factors associated with clinically severe disease. Subjects were identified from the South Australian Myositis Database (SAMD), a histologically defined registry. Consecutive muscle sections from patients with IMNM (n = 62), other forms of IIM (n = 60) and histologically normal muscle (n = 17) were stained using immunohistochemistry and graded. Clinical information was collected from the SAMD and through retrospective chart review. IMNM patients displayed clinical and histological heterogeneity. While most (67%) were profoundly weak at presentation, 24% exhibited mild to moderate weakness and 9% had normal power. Histological myonecrosis ranged from minor to florid. The amount of myofibre complement deposition was closely associated with clinical severity. Patients of Aboriginal and Torres Strait Islander heritage and those with anti-SRP autoantibodies present with a severe phenotype. Despite intense immunotherapy, few IMNM patients recovered full power at one year follow up. The identification of clinical, serological and histological features which are associated with severe forms of the disease may have diagnostic and therapeutic utility.

Road user behaviour, attitudes and crashes: a survey of Aboriginal and Torres Strait Islander people in Australia.

OBJECTIVE: This study aimed to describe road user behaviour, attitudes and crashes in Aboriginal and Torres Strait Islander people in four urban, regional and remote communities located in New South Wales (NSW) and South Australia (SA). METHODS: Face-to-face surveys were administered to clients (n=625) in Aboriginal Community Controlled Health Services (ACCHS). All Aboriginal and Torres Strait Islander clients attending the ACCHS for any reason were approached to participate over a 2-week period. Surveys included questions on sociodemographic factors, crash involvement, road behaviours and road safety attitudes drawn from tools used in national surveys. RESULTS: The participation rate was high (69%-75%). Seat belt wearing rates were very high, particularly in the front of a car, although rear seat belt wearing rates in SA (77%) were substantially lower than in NSW (93%). Among drivers, 11% reported always or mostly driving 10 km/hour over the speed limit, and this was higher among drivers in SA (13.4%). Drivers aged 55 years and over and/or women were more likely to report that they do not drink at any time or restricted what they drank when driving. These results enable comparison with the Community Attitude to Road Safety survey conducted Australia-wide in 2013. CONCLUSIONS: This study confirms that Aboriginal and Torres Strait Islander people are inclined to report attitudes or road safety behaviours similar to the rest of the population; however, rear restraint use was lower and self-reported speeding was higher. These issues are likely attributable to transport options and geography in remote communities, which can contribute to overcrowding and unsafe driving practices.

Lifetime risk of child protection system involvement in South Australia for Aboriginal and non-Aboriginal children, 1986-2017 using linked administrative data.

BACKGROUND: Child protection services exist to reduce potential harms from child maltreatment. Many jurisdictions produce annual data on child protection system (CPS) involvement, leaving a gap in knowledge of lifetime involvement. OBJECTIVE: To describe lifetime involvement in CPS, by type of contact. PARTICIPANTS: All 608,547 children born in South Australia (SA), Australia between 1986 and 2017. METHODS: A retrospective cohort design using linked administrative data to report cumulative incidence of CPS involvement from birth to age <18 (or June30 2017) by Aboriginal status. CPS involvement was categorised into notifications (3 levels), investigations, substantiations and out-of-home care (OOHC). Cumulative incidence curves were derived for 5 birth cohorts. RESULTS: Across childhood (to age <18 years), substantiated maltreatment was experienced by 3.2-3.6% of non-Aboriginal and 19-25% of Aboriginal children, 7 times reported annual substantiation rates. For most CPS categories CPS involvement increased until 2010, and was occurring earlier in life. By age 3, 0.5% of non-Aboriginal and 4.5% of Aboriginal children born 1986-1991 were the subject of a substantiation compared with 1.9% and 15% of non-Aboriginal and Aboriginal children, respectively, born 2010-2017. Incidence rates beyond age 3 were similar. OOHC contact was similar across cohorts, with ˜1.5% of non-Aboriginal and 12.7% of Aboriginal children ever-placed in care. CONCLUSIONS: Data linkage is an essential tool for understanding life course involvement with the CPS and describing trends not observable from annual snapshots. Such information is critical for burden of disease estimates, informing policy and monitoring CPS performance.

Mindfulness and Acceptance-Based Group Therapy: An Uncontrolled Pragmatic Pre-Post Pilot Study in a Heterogeneous Population of Female Prisoners.

The rate of females imprisoned worldwide has increased by more than 50% during the last two decades, with recent figures suggesting that, worldwide, the female prison population may still be increasing at a faster rate than males. Despite prevalence rates for psychiatric conditions among female prisoners being significantly higher than males, there is a particular lack of programs specifically designed for women. This preliminary study evaluates the initial effectiveness of a mindfulness and acceptance-based group program in an uncontrolled pragmatic pilot study of a heterogeneous group of incarcerated women with a range of mental health issues. Participants were 59 incarcerated women who engaged in a 10-session group program. Outcome measures comprised the Acceptance and Action Questionnaire-II, Depression Anxiety and Stress Scale, Mindfulness Attention Awareness Scale, and three screening tools derived from the full version of the Patient Health Questionnaire (PHQ-9), to measure depression, binge eating (Patient Health Questionnaire-Binge Eating Disorder [PHQ-ED]), and somatoform disorders (PHQ-15). Results of linear mixed modelling showed improvements in mindfulness and acceptance, and reductions in depression, anxiety, and somatoform symptoms. Furthermore, acceptance and commitment therapy (ACT) was shown to be an acceptable and feasible intervention for female Indigenous Australian prisoners. A mindfulness and acceptance-based group approach appears to be feasible and acceptable in a prison environment for a female prisoners with a range of mental health symptomatology.

Disparities in breast screening, stage at diagnosis, cancer treatment and the subsequent risk of cancer death: a retrospective, matched cohort of aboriginal and non-aboriginal women with breast cancer.

BACKGROUND: Australia's Aboriginal and Torres Strait Islander women have poorer survival and twice the disease burden from breast cancer compared to other Australian women. These disparities are influenced, but not fully explained, by more diagnoses at later stages. Incorporating breast screening, hospital and out of hospital treatment and cancer registry records into a person-linked data system can improve our understanding of breast cancer outcomes. We focussed one such system on a population-based cohort of Aboriginal women in South Australia diagnosed with breast cancer and a matched cohort of non-Aboriginal women with breast cancer. We quantify Aboriginal and non-Aboriginal women's contact with publicly funded screening mammograms; quantify exposure to a selection of cancer treatment modalities; then assess the relationship between screening, treatment and the subsequent risk of breast cancer death. METHODS: Breast cancers registered among Aboriginal women in South Australia in 1990-2010 (N = 77) were matched with a random selection of non-Aboriginal women by birth and diagnostic year, then linked to screening records, and treatment 2 months before and 13 months after diagnosis. Competing risk regression summarised associations of Aboriginality, breast screening, cancer stage and treatment with risk of breast cancer death. RESULTS: Aboriginal women were less likely to have breast screening (OR = 0.37, 95%CIs 0.19-0.73); systemic therapies (OR = 0.49, 95%CIs 0.24-0.97); and, surgical intervention (OR = 0.35, 95%CIs 0.15-0.83). Where surgery occurred, mastectomy was more common among Aboriginal women (OR = 2.58, 1.22-5.46). Each of these factors influenced the risk of cancer death, reported as sub-hazard ratios (SHR). Regional spread disease (SHR = 34.23 95%CIs 6.76-13.40) and distant spread (SHR = 49.67 95%CIs 6.79-363.51) carried more risk than localised disease (Reference SHR = 1). Breast screening reduced the risk (SHR = 0.07 95%CIs 0.01-0.83). So too did receipt of systemic therapy (SHR = 0.06 95%CIs 0.01-0.41) and surgical treatments (SHR = 0.17 95%CIs 0.04-0.74). In the presence of adjustment for these factors, Aboriginality did not further explain the risk of breast cancer death. CONCLUSION: Under-exposure to screening and treatment of Aboriginal women with breast cancers in South Australia contributed to excess cancer deaths. Improved access, utilisation and quality of effective treatments is needed to improve survival after breast cancer diagnosis.

Aboriginal women have a higher risk of cervical abnormalities at screening; South Australia, 1993-2016.

OBJECTIVE: Cervical cancer mortality has halved in Australia since the national cervical screening program began in 1991, but elevated mortality rates persist for Aboriginal and Torres Strait Islander women (referred to as Aboriginal women in this report). We investigated differences by Aboriginal status in abnormality rates predicted by cervical cytology and confirmed by histological diagnoses among screened women. METHODS: Using record linkage between cervical screening registry and public hospital records in South Australia, we obtained Aboriginal status of women aged 20-69 for 1993-2016 (this was not recorded by the registry). Differences in cytological abnormalities were investigated by Aboriginal status, using relative risk ratios from mixed effect multinomial logistic regression modelling. Odds ratios were calculated for histological high grade results for Aboriginal compared with non-Aboriginal women. RESULTS: Of 1,676,141 linkable cytology tests, 5.8% were abnormal. Abnormal results were more common for women who were younger, never married, and living in a major city or socioeconomically disadvantaged area. After adjusting for these factors and numbers of screening episodes, the relative risk of a low grade cytological abnormality compared with a normal test was 14% (95% confidence interval 5-24%) higher, and the relative risk of a high grade cytological abnormality was 61% (95% confidence interval 44-79%) higher, for Aboriginal women. The adjusted odds ratio of a histological high grade was 76% (95% confidence interval 46-113%) higher. CONCLUSIONS: Ensuring that screen-detected abnormalities are followed up in a timely way by culturally acceptable services is important for reducing differences in cervical cancer rates between Aboriginal and non-Aboriginal women.

Forecasting and foreclosing futures: The temporal dissonance of advance care directives.

Advance care directives situate persons as rational and self-determining actors who can make anticipatory plans about their futures. This paper critically examines how people interpret individual and future-oriented approaches to medical decision-making with limited access to information and knowledge, and reduced opportunities to prepare and document their care preferences. Based on ethnographic research with Asian migrant families living in Adelaide, South Australia (August 2015-July 2018), it reveals a discord between planning for a finite future and the contingencies and continuities of social life. It unsettles the detached reasoning that is privileged in end-of-life decision-making and reveals limitations to "do-it-yourself" approaches to advance care directives which, it will be argued, not only forecasts potential futures but also forecloses them. Taking Derrida's critique of death and decision-making as a point of departure, it develops the concept of temporal dissonance as a theoretical framework to articulate the tensions that are constituted in advance care directives. The paper suggests that attention to temporal incongruities may help to shed light on the many complex interpretations of advance care directives and the difficulties of promoting them in diverse contexts.

Associations between weight change and biomarkers of cardiometabolic risk in South Asians: secondary analyses of the PODOSA trial.

BACKGROUND/OBJECTIVES: The association of weight changes with cardiometabolic biomarkers in South Asians has been sparsely studied. SUBJECTS/METHODS: We measured cardiometabolic biomarkers at baseline and after 3 years in the Prevention of Diabetes and Obesity in South Asians Trial. We investigated the effect of a lifestyle intervention on biomarkers in the randomized groups. In addition, treating the population as a single cohort, we estimated the association between change in weight and change in biomarkers. RESULTS: Complete data were available at baseline and after 3 years in 151 participants. At 3 years, there was an adjusted mean reduction of 1·44 kg (95% confidence interval (95% CI): 0.18-2.71) in weight and 1.59 cm (95% CI: 0.08-3.09) in waist circumference in the intervention arm as compared with the control arm. There was no clear evidence of difference between the intervention and control arms in change of mean value of any biomarker. As a single cohort, every 1 kg weight reduction during follow-up was associated with a reduction in triglycerides (-1.3%, P=0.048), alanine aminotransferase (-2.5%, P=0.032), gamma-glutamyl transferase (-2.2%, P=0.040), leptin (-6.5%, P<0.0001), insulin (-3.7%, P=0.0005), fasting glucose (-0.8%, P=0.0071), 2-h glucose (-2.3%, P=0.0002) and Homeostatic Model Assessment of insulin resistance (HOMA-IR: -4.5%, P=0.0002). There was no evidence of associations with other lipid measures, tissue plasminogen activator, markers of inflammation or blood pressure. CONCLUSIONS: We demonstrate that modest weight decrease in SAs is associated with improvements in markers of total and ectopic fat as well as insulin resistance and glycaemia in South Asians at risk of diabetes. Future trials with more intensive weight change are needed to extend these findings.

Management of Indigenous patients presenting with non ST-segment elevation acute coronary syndrome in South Australia: a retrospective cohort study.

AIM: Using Australian guidelines for management of acute coronary syndromes, we assessed the probability of an Indigenous patient receiving interventional and therapeutic care after presenting in two metropolitan hospitals. METHODS: A retrospective case note review of patients admitted through two Adelaide public tertiary hospital emergency departments from December 2007 to December 2009. The study cohort was 488 patients with high-risk clinical features without ST-segment elevation. RESULTS: Indigenous patients were significantly younger, present later in the disease process and have a higher burden of cardiovascular risk factors when compared with non-Indigenous patients. Indigenous patients were 54% more likely to receive angiography (Risk ratios (RR) = 1.54; 95% CI 1.31; 1.81) than non-Indigenous patients, however, this difference disappeared after adjustment for age, sex and propensity score. Indigenous patients were 20% more likely to receive the recommended medications (RR = 1.19, 95% CI 1.01; 1.40) compared with non-Indigenous patients. Patients over 65 years were 53% less likely to receive an angiogram (RR = 0.47, 95% CI 0.38; 0.56) and were 35% less likely to receive the recommended medications (RR = 0.65, 95% CI 0.54; 0.78) than a patient at the ages of 18-49. Women were almost 20% less likely to receive an angiogram (RR = 0.81, 95% CI 0.66; 0.99) and 20% less likely to receive the recommended medications (RR = 0.80, 95% CI 0.71; 0.91) when compared with men. The likelihood of receiving medications on discharge was significantly influenced by age, gender, ethnicity, comorbid burden and revascularisation. CONCLUSIONS: The younger age and significantly higher-risk profile of Indigenous adults presenting to SA hospitals with acute coronary syndromes appears to lead to different management decisions, which may well be led by patient factors. Many of these risk conditions can be better managed in the primary care setting.

Self-efficacy and self-rated oral health among pregnant aboriginal Australian women.

BACKGROUND: Self-efficacy plays an important role in oral health-related behaviours. There is little known about associations between self-efficacy and subjective oral health among populations at heightened risk of dental disease. This study aimed to determine if low self-efficacy was associated with poor self-rated oral health after adjusting for confounding among a convenience sample of pregnant women. METHODS: We used self-reported data from 446 Australian women pregnant with an Aboriginal child (age range 14-43 years) to evaluate self-rated oral health, self-efficacy and socio-demographic, psychosocial, social cognitive and risk factors. Hierarchical entry of explanatory variables into logistic regression models estimated prevalence odds ratios (POR) and 95% confidence intervals (95% CI) for fair or poor self-rated oral health. RESULTS: In an unadjusted model, those with low self-efficacy had 2.40 times the odds of rating their oral health as 'fair' or 'poor' (95% CI 1.54-3.74). Addition of socio-demographic factors attenuated the effect of low self-efficacy on poor self-rated oral health by 10 percent (POR 2.19, 95% CI 1.37-3.51). Addition of the psychosocial factors attenuated the odds by 17 percent (POR 2.07, 95% CI 1.28-3.36), while addition of the social cognitive variable fatalism increased the odds by 1 percent (POR 2.42, 95% CI 1.55-3.78). Inclusion of the behavioural risk factor 'not brushing previous day' attenuated the odds by 15 percent (POR 2.11, 95%CI 1.32-3.36). In the final model, which included all covariates, the odds were attenuated by 32 percent (POR 1.80, 95% CI 1.05, 3.08). CONCLUSIONS: Low self-efficacy persisted as a risk indicator for poor self-rated oral health after adjusting for confounding among this vulnerable population.

Study Protocol: establishing good relationships between patients and health care providers while providing cardiac care. Exploring how patient-clinician engagement contributes to health disparities between indigenous and non-indigenous Australians in South Australia.

BACKGROUND: Studies that compare Indigenous Australian and non-Indigenous patients who experience a cardiac event or chest pain are inconclusive about the reasons for the differences in-hospital and survival rates. The advances in diagnostic accuracy, medication and specialised workforce has contributed to a lower case fatality and lengthen survival rates however this is not evident in the Indigenous Australian population. A possible driver contributing to this disparity may be the impact of patient-clinician interface during key interactions during the health care process. METHODS/DESIGN: This study will apply an Indigenous framework to describe the interaction between Indigenous patients and clinicians during the continuum of cardiac health care, i.e. from acute admission, secondary and rehabilitative care. Adopting an Indigenous framework is more aligned with Indigenous realities, knowledge, intellects, histories and experiences. A triple layered designed focus group will be employed to discuss patient-clinician engagement. Focus groups will be arranged by geographic clusters i.e. metropolitan and a regional centre. Patient informants will be identified by Indigenous status (i.e. Indigenous and non-Indigenous) and the focus groups will be convened separately. The health care provider focus groups will be convened on an organisational basis i.e. state health providers and Aboriginal Community Controlled Health Services. Yarning will be used as a research method to facilitate discussion. Yarning is in congruence with the oral traditions that are still a reality in day-to-day Indigenous lives. DISCUSSION: This study is nestled in a larger research program that explores the drivers to the disparity of care and health outcomes for Indigenous and non-Indigenous Australians who experience an acute cardiac admission. A focus on health status, risk factors and clinical interventions may camouflage critical issues within a patient-clinician exchange. This approach may provide a way forward to reduce the appalling health disadvantage experienced within the Indigenous Australian communities.

A critical review of the literature: engendering the discourse of masculinities matter for parenting African refugee men.

According to the literature on culturally and linguistically diverse parenting, refugee parenting practices and styles that are normative in countries of origin may not be sanctioned in Australia. In the case of refugee parenting, beliefs, practices, and values may be decentered in pre-resettlement contexts where survival becomes the primary concern. Engendering the discourse of masculinities to reflect a relationship between child protection and the experience of refugee parenting for African men in both pre- and post-resettlement contexts will inform culturally competent practice, intervention, and community development that is inclusive of their gender-specific needs. This article brings an expanded masculinities perspective to the ecology of refugee parenting for resettled African men resulting from larger research findings with focus group participants. Incorporating notions of masculinity into the child protection discourse is an attempt not only to reduce existing gender under- and misrepresentation among South Australian refugees but also to ensure greater visibility and increase the role of refugee men in the process of developing culturally relevant and appropriate policies, practices, and services to assist successful resettlement transitions while strengthening family well-being. The concept of masculinities, this article argues, must be treated as integral to any approach to working with refugees, particularly in areas that penetrate and may define the quality of their life experiences, expectations, and aspirations. Masculinities matter. Exploring refugee male perceptions, interpretations, and enactment of masculinity may unmask the differential experiences of refugee women from men and ensure the integration and operationalization of these differences into child protection services and practice.
