Multilingual Repertoires at Play: Structure and Function in Reported Speech Utterances of Alyawarr Children

While there is increasing international interest in approaching language analysis with the prism of repertoire, research on repertoire on the Australian continent is still very much in the shadow of “traditional” language-centric documentary work. This paper will explore the question of how users of Australian, English-lexified contact varieties exploit their multilingual repertoires to achieve local, conversation–organizational ends. Drawing upon a corpus of video recordings from Ipmangker, a Central Australian Aboriginal community, and using the analytical methods of interactional and comparative variationist linguistics, I examine the production of reported speech by four 6- to 7-year-old Alyawarr children in a play session at home. A set of prosodic, phonological, morphological and discourse-pragmatic features are shown to form a coherent set of linguistic elements with which these multilingual children can contrast reported speech from the surrounding talk. Moreover, the use of reported speech in play not only allows the children to organize their interaction, but responds to and constructs the epistemic landscape of play.

Feasibility of Implementing Infant Home Visiting in a Central Australian Aboriginal Community

The Australian Nurse-Family-Partnership Program, an adaption of the Olds’ Nurse-Family-Partnership (NFP), commenced in Alice Springs in 2009 (Central Australia FPP), aiming to improve the health and social outcomes of Aboriginal mothers and infants. This study explores the feasibility of NFP implementation in a remote Australian Aboriginal community. Feasibility was defined by programme uptake by eligible women, retention in the programme, actual vs. scheduled visits and extent of programme content delivery. Programme uptake was established from pregnancy data in the patient Clinical Information System and programme referrals to December 31, 2015. Rates of withdrawal, retention and content delivery were derived from FPP data and compared with published NFP data. Modified Poisson regression was used to identify client characteristics associated with retention beyond the child’s first birthday. There were 469 valid referrals (43% of eligible pregnancies) and 299 women with at least one completed home visit by December 31, 2015. Of these, 41% completed the programme to the child’s second birthday and 53% beyond the child’s first birthday. Dominant reasons for leaving were “moved out of service area” (35%) and “declined further participation” (35%). There was a statistically significant positive association for programme retention with later gestational age at referral (RR = 1.27, p value = 0.03). A high proportion (75%) of scheduled visits was achieved and high delivery of programme content (80%). Central Australia FPP is the first implementation of the NFP model in a remote Aboriginal community. This study found that it can be implemented successfully in this setting. Outcome evaluation is needed to test achievement of hypothesised benefits.

Community and clinic-based screening for curable sexually transmissible infections in a high prevalence setting in Australia: a retrospective longitudinal analysis of clinical service data from 2006 to 2009.

Background In response to the high prevalence of sexually transmissible infections (STIs) in many central Australian Aboriginal communities, a community-wide screening program was implemented to supplement routine primary health care (PHC) clinic testing. The uptake and outcomes of these two approaches were compared. Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) community and clinic screening data for Aboriginal people aged 15-34 years, 2006-2009, were used. Regression analyses assessed predictors of the first test occurring in the community screen, positivity and repeat testing. A total of 2792 individuals had 9402 tests (median: four per person) over 4 years. Approximately half of the individuals (54%) were tested in the community and clinic approaches combined, 29% (n=806) in the community screen only and 18% (n=490) in the clinic only. Having the first test in a community screen was associated with being male and being aged 15-19 years. There was no difference between community and clinic approaches in CT or NG positivity at first test. More than half (55%) of individuals had a repeat test within 2-15 months and of these, 52% accessed different approaches at each test. The only independent predictor of repeat testing was being 15-19 years. STI screening is an important PHC activity and the findings highlight the need for further support for clinics to reach young people. The community screen approach was shown to be a useful complementary approach; however, cost and sustainability need to be considered.

Nutritional predictors of successful chronic disease prevention for a community cohort in Central Australia.

To investigate biomarkers of nutrition associated with chronic disease absence for an Aboriginal cohort. Screening for nutritional biomarkers was completed at baseline (1995). Evidence of chronic disease (diabetes, CVD, chronic kidney disease or hypertension) was sought from primary health-care clinics, hospitals and death records over 10 years of follow-up. Principal components analysis was used to group baseline nutritional biomarkers and logistic regression modelling used to investigate associations between the principal components and chronic disease absence. Three Central Australian Aboriginal communities. Aboriginal people (n 444, 286 of whom were without chronic disease at baseline) aged 15-82 years. Principal components analysis grouped twelve nutritional biomarkers into four components: 'lipids'; 'adiposity'; 'dietary quality'; and 'habitus with inverse quality diet'. For the 286 individuals free of chronic disease at baseline, lower adiposity, lower lipids and better dietary quality components were each associated with the absence at follow-up of most chronic diseases examined, with the exception of chronic kidney disease. Low 'adiposity' component was associated with absence of diabetes, hypertension and CVD at follow-up. Low 'lipid' component was associated with absence of hypertension and CVD, and high 'dietary quality' component was associated with absence of CVD at follow-up. Lowering or maintenance of the factors related to 'adiposity' and 'lipids' to healthy thresholds and increasing access to a healthy diet appear useful targets for chronic disease prevention for Aboriginal people in Central Australia.

Cost of best-practice primary care management of chronic disease in a remote Aboriginal community.

To estimate the cost of completing all chronic care tasks recommended by the Central Australian Rural Practitioners Association Standard Treatment Manual (CARPA STM) for patients with type 2 diabetes and chronic kidney disease (CKD). The study was conducted at a health service in a remote Central Australian Aboriginal community between July 2010 and May 2011. The chronic care tasks required were ascertained from the CARPA STM. The clinic database was reviewed for data on disease prevalence and adherence to CARPA STM guidelines. Recommended tasks were observed in a time-and-motion study of clinicians' work. Clinicians were interviewed about systematic management and its barriers. Expenditure records were analysed for salary and administrative costs. Diabetes and CKD prevalence; time spent on chronic disease care tasks; completion of tasks recommended by the CARPA STM; barriers to systematic care identified by clinicians; and estimated costs of optimal primary care management of all residents with diabetes or CKD. Projected annual costs of best-practice care for diabetes and CKD for this community of 542 people were $900 792, of which $645 313 would be met directly by the local primary care service. Estimated actual expenditure for these conditions in 2009-10 was $446 585, giving a projected funding gap of $198 728 per annum, or $1733 per patient. High staff turnover, acute care workload and low health literacy also hindered optimal chronic disease care. Barriers to optimal care included inadequate funding and workforce issues. Reduction of avoidable hospital admissions and overall costs necessitates adequate funding of primary care of chronic disease in remote communities.

At the Heart of Learning (Series: Paper 2 of 4): Witulya Mulapa nganana Mantjintjaku: From Cultural Devastation to Cultural Re-Invention

For remote Central Australian Aboriginal communities, the world has changed completely and irrevocably in the space of a lifetime. Drawing on Jonathan Lear's (2006) Radical Hope, the authors highlight the comparative struggles outlined in Lear's reflection on the life of Crow Indian chief Plenty Coups. For Anangu (Pitjantjatjara/Yankunytjatjara people), the same question that confronted Plenty Coups arises: “How can Anangu pursue a ‘virtuous’ Anangu existence in a world where ‘being Anangu’ no longer ‘makes any sense’?” The authors explore the possibilities of choosing cultural re-invention over resigning to a sense of “the end” and consider how the recognition and retention of long-held values might benefit the broader experience of education, rather than be considered as a barrier or constraint to “success”.

Prevalences of overweight and obesity among children in remote Aboriginal communities in central Australia

The chronic diseases associated with overweight and obesity are major contributors to the excess disease burden of Aboriginal Australians. Surveillance of overweight and obesity is required to monitor these conditions, and to develop and evaluate interventions to improve health and wellbeing. Remote Aboriginal communities in Australia's Northern Territory (NT) are where approximately two-thirds of the NT Aboriginal people live, a proportion which has been stable over many years. However the remote communities suffer significant socioeconomic disadvantage including limited education and employment opportunities, and poor quality and overcrowded housing. Approximately one-third of Aboriginal people in NT live in central Australia, which consists of the Alice Springs and Barkly districts. The Healthy School-Aged Kids Program includes health promotion and child health screening, and is run in remote Aboriginal communities of NT. This report provides estimates of prevalences of overweight and obesity among children in central Australia who participated in health checks as part of Healthy School-Aged Kids Program in 2010. All children in remote central Australian Aboriginal communities were invited to participate in health checks. Children who attended were weighed and measured. Date of birth, sex, height and weight for each child were used to determine prevalence of overweight (≥+1 standard deviation [SD] BMI-for-age) and obesity (≥+2 SD BMI-for-age) according to WHO Growth standards. Differences in proportions of overweight and obesity by age group and sex, and their statistical significance were calculated. Weight, height, sex and age data were available for 996 children from a population of 1764. It was found that 22.1% of girls and 20.7% of boys were overweight; and 5.1% of girls and 5.8% of boys were obese as defined by BMI-for-age. Prevalence of overweight but not obesity increased with age (for overweight z=3.28, p=0.0011; for obesity z=0.68; p=0.50). The prevalences of overweight and obesity as estimated by BMI-for-age among children in remote central Australian Aboriginal communities were compared with those in other Australian surveys. They appear unlikely to reflect future relative risk of the chronic diseases with which overweight and obesity are associated. Routine collection of data on BMI-for-age may not provide adequate estimation of future risk of chronic disease burden attributable to overweight and obesity among these children. Alternative measures for surveillance for overweight such as waist circumference may prove more useful. Appropriate interventions to reduce risk of chronic disease are required, including interventions to reduce prevalences of overweight and obesity.

Apparent Contrasting Rates of Pharyngitis and Pyoderma in Regions where Rheumatic Heart Disease is Highly Prevalent

The aim of the study was to describe the epidemiology of pharyngitis and pyoderma in a Central Australian Aboriginal community with a high prevalence of rheumatic heart disease (RHD) and compare it to communities in the Top End of the Northern Territory. Following ethics approval and community consultation, selected households were enrolled and visited over a 13-month period. People were asked if they had a sore throat and/or skin sores and asked about current or recent use of antibiotics; all throats and any pyoderma lesions were swabbed for bacterial culture. Beta-haemolytic streptococci (BHS), including group A streptococcus (GAS), were identified in the central laboratory using standard methods. Household crowding was also assessed. Results were then compared to those from the Top End study. Sore throat was relatively common (480 episodes per 100 person years), although there was only one case of GAS pharyngitis in 326 consultations. Only 5.5% of children <15 years had pyoderma during the course of the study. This is the opposite picture to that reported in the Top End where symptomatic pharyngitis is rare and pyoderma is common. Although the data are limited, the epidemiology of pharyngitis and pyoderma in this Central Australian Aboriginal community appears to be more akin to that seen in temperate climates rather than tropical Top End communities. In this community, RHD preventative measure should continue to include aggressive treatment of pharyngitis according to recommendations.

The Historical Context of Developing an Aboriginal Community-Controlled Health Service: A Social History of the First Ten Years of the Central Australian Aboriginal Congress

Since 1973, the Alice Springs-based communitycontrolled comprehensive primary health service, the Central Australian Aboriginal Congress Inc. (CAAC), has pursued a broad agenda addressing the social and health needs of the local population. This paper outlines the local and national context and the reasons why the central Australian Aboriginal community decided to establish its own organisation to address social issues and health service provision. The broad social and policy influence of the organisation will be considered in both its historical and contemporary context.

Aboriginal women working in vocational training and education: a story from Central Australia

This article outlines research undertaken by an Aboriginal women’s non‐government organization (NGO) into vocational training and education (VTE) needs and issues for remote Aboriginal communities in Central Australia. It describes the Central Australian context, and in particular the impact of remoteness, inequity and disadvantage upon Aboriginal people’s access to and participation in VTE. Waltja Tjutangku Palyapayi (Waltja) is an Aboriginal NGO based in Alice Springs, at the centre of the desert region of inland Australia. Waltja supports the development of family services and the self‐determination of remote Central Australian Aboriginal communities. Senior Aboriginal women from widespread communities govern Waltja. In their communities, and working with and through Waltja, women play a significant role in identification of training needs, advocacy for their communities, and facilitation of education and training, including VTE. This article outlines Waltja’s research over the past decade into training needs and issues and documents the organizational ‘journey’ of this Aboriginal NGO into and within the VTE system. In particular, the article discusses Waltja’s ‘Training Nintiringtjaku’ initiative to develop a professional role for Aboriginal community leaders mediating between the VTE system and their communities.

Increase in prevalence of obesity and diabetes and decrease in plasma cholesterol in a central Australian aboriginal community.

To document change in prevalence of obesity, diabetes and other cardiovascular disease (CVD) risk factors, and trends in dietary macronutrient intake, over an eight-year period in a rural Aboriginal community in central Australia. Sequential cross-sectional community surveys in 1987, 1991 and 1995. All adults (15 years and over) in the community were invited to participate. In 1987, 1991 and 1995, 335 (87% of eligible adults), 331 (76%) and 304 (68%), respectively, were surveyed. Body mass index and waist: hip ratio; blood glucose level and glucose tolerance; fasting total and high density lipoprotein (HDL) cholesterol and triglyceride levels; and apparent dietary intake (estimated by the store turnover method). A community-based nutrition awareness and healthy lifestyle program, 1988-1990. At the eight-year follow-up, the odds ratios (95% CIs) for CVD risk factors relative to baseline were obesity, 1.84 (1.28-2.66); diabetes, 1.83 (1.11-3.03); hypercholesterolaemia, 0.29 (0.20-0.42); and dyslipidemia (high triglyceride plus low HDL cholesterol level), 4.54 (2.84-7.29). In younger women (15-24 years), there was a trembling in obesity prevalence and a four- to fivefold increase in diabetes prevalence. Store turnover data suggested a relative reduction in the consumption of refined carbohydrates and saturated fats. Interventions targeting nutritional factors alone are unlikely to greatly alter trends towards increasing prevalences of obesity and diabetes. In communities where healthy food choices are limited, the role of regular physical activity in improving metabolic fitness may also need to be emphasised.

A targeted, single-dose azithromycin strategy for trachoma.

To evaluate the impact of treating children with acute trachoma and their contacts with oral azithromycin. Open, uncontrolled, prospective evaluation of a community-based treatment strategy. Central Australian semi-desert Aboriginal community (1995-1996). 216 school- and pre-schoolchildren aged 6 months and up to 15 years. All children with acute trachoma and their contacts (co-resident siblings aged between 6 months and 15 years) received single-dose oral azithromycin suspension (20 mg/kg, to a maximum of 1000 mg). Prevalence of acute trachoma (World Health Organization trachoma diagnostic criteria). Trachoma prevalence at baseline was 42% (71/169) and 55% (18/33) for schoolchildren and pre-schoolchildren, respectively: 103 schoolchildren and 21 pre-schoolchildren, comprising 77 with follicular trachoma and their 47 contacts, were treated with azithromycin over an 8-week period. Acute trachoma prevalence in schoolchildren fell to 22% at 6-8 months (P < 0.0001) and was 31% at 12 months (P < 0.05 compared with baseline). Pre-schoolchildren were followed up for 6 months after treatment, and their trachoma prevalence fell from 55% to 25% (P < 0.05). Further treatment was given to children with trachoma at 12 months, and the point prevalence of trachoma for schoolchildren at 24 months was 34%. In contrast to mass-treatment strategies, significant reductions in trachoma prevalence at 6 months were achieved by screening 35% of community members (216) and treating 20% (124). The subsequent prevalence increases support the need for more comprehensive treatment programs, including health promotion and efforts to improve living conditions.

Abnormal glucose tolerance and other coronary heart disease risk factors in an isolated aboriginal community in central Australia.

To determine the age- and sex-specific prevalence of diabetes, impaired glucose tolerance (IGT), and coronary heart disease risk factors in a remote central Australian Aboriginal community maintaining some degree of traditional lifestyle, living in homeland communities on their ancestral land. A cross-sectional survey of 437 subjects > or = 15 years of age (189 men, 248 women), representing 80% of the adult population residing in the community at the time of the survey, was performed and the following parameters measured: BMI, glucose tolerance, circulating insulin and lipids, and blood pressure. The mean BMI for this population was 22.9 +/- 4.8 kg/m2. The prevalence of diabetes in the age group of 15-34 years (103 men and 140 women) was 2 and 6% for men and women, respectively. In the 35-years-and-older age group (86 men and 108 women), diabetes prevalence was 19 and 13% for men and women, respectively. Over half the diabetic subjects did not exhibit fasting hyperglycemia. IGT occurred in 8 and 15% of younger men and women, respectively, and in 17 and 32% of older men and women, respectively. Smoking was common among men (53% current smokers) but rare among women (2% current smokers). The prevalence of hypercholesterolemia, hypertriglyceridemia, hypertension, and overweight rose with increasing degrees of glucose intolerance. The two communities adjacent to the only store in the area had a higher prevalence of abnormal glucose tolerance than did the more remote homeland communities (odds ratio for abnormal glucose tolerance: 2.92; 95% CI 1.51-5.63). Despite their relative leanness, this Aboriginal population exhibited relatively high prevalences of IGT and diabetes without fasting hyperglycemia. The data suggest a protective effect of a decentralized mode of living, as opposed to a more urbanized lifestyle, on the occurrence of glucose intolerance. Abnormal lipid profiles (particularly high triglycerides and low HDL cholesterol) and the high prevalence of smoking in men indicated a high-risk profile for coronary heart disease in this population.

Paediatric urolithiasis in a remote Australian aboriginal community.

A retrospective study of Community Health Service patient records revealed 10 cases of urolithiasis in Aboriginal children under 5 years of age in a remote central Australian Aboriginal community over a 4 year period, out of a total under-5 population estimate of 62. The highest attack rate was in the 0-2 age group, where nearly one in 10 children presented per year. All children had significant associated morbidity. Two children underwent pyelolithotomy. Aboriginal children in the remote arid zone study community suffer exceptionally high rates of urolithiasis. Inadequate diet, dehydration and recurrent infectious disease are factors in pathogenesis. Further study may elucidate aetiology, but the implications of these data for improving environmental conditions and health service delivery in Aboriginal communities are urgent.

Food‐purchasing behaviour in an Aboriginal community. 1. Results of a survey

Attempts to improve the nutritional status of Aboriginal people through nutritional education programs should be informed by an understanding of contemporary patterns of food procurement, preparation and distribution. This paper describes the results of a survey of food-purchasing behaviour in a central-Australian Aboriginal community. Every transaction occurring in each food outlet in the community over a two-week period was recorded and the data analysed. The results show that women play a much greater role than men in food purchasing, that there is a significant recourse to takeaway foods, that there is a cycle of expenditure determined by distribution of pension and Community Development Employment Project cheques, and that children have sufficient disposable income to be able to provision themselves from the food outlets, so that much of their food consumption is not determined by adult members of their family.

Obesity, diabetes, and hyperlipidemia in a central Australian aboriginal community with a long history of acculturation.

To determine the age- and sex-specific prevalence of diabetes and to examine associations between related anthropometric and metabolic abnormalities in an Aboriginal community in central Australia with a long history of acculturation. We used a cross-sectional survey of 353 adults > 15 yr of age (87% response rate) and measured the following parameters: weight, height, circumferences of waist and hips; glucose, insulin, cholesterol, triglyceride, and high-density lipoprotein cholesterol in fasting plasma; and plasma glucose and insulin 2 h after 75 g oral glucose. The prevalence of diabetes was 29.6% in survey participants > 35 yr of age and 5.3% in those < 35 yr of age. Impaired glucose tolerance also occurred with higher frequency in those > 35 yr of age (14.8 vs. 4.7%). Of those > 35 yr of age, 75% of the women and 51% of the men were overweight or obese, with a body mass index > or = 25 kg/m2. A large insulin response to oral glucose was evident, with the upper tertile of the 2-h insulin response six times higher than the lower tertile (113 +/- 43 vs. 19 +/- 8 mU/L). Hyperinsulinemia showed a strong, positive association with impaired glucose tolerance, body mass index, waist-to-hip ratio, cholesterol, and triglyceride levels and a negative association with high-density lipoprotein cholesterol levels. Cholesterol levels were on average 0.5 mM higher in men than in women. Deteriorations in carbohydrate and lipid metabolism occurred before 40 yr of age: diabetes, body mass index, waist-to-hip ratio, and fasting triglycerides and cholesterol concentrations peaked and high-density lipoprotein cholesterol concentrations reached their nadir at the end of the fourth decade. These data suggest that any intervention programs developed to prevent or reduce diabetes prevalence in this population should be targeted at adolescents and young adults.
