Lung Cancer Screening by Race and Ethnicity in an Integrated Health System in Hawaii.

Importance: Racial and ethnic differences in lung cancer screening (LCS) completion and follow-up may be associated with lung cancer incidence and mortality rates among high-risk populations. Aggregation of Asian American, Native Hawaiian, and Pacific Islander racial and ethnic groups may mask the true underlying disparities in screening uptake and diagnostic follow-up, creating barriers for targeted, preventive health care. Objective: To examine racial and ethnic differences in LCS completion and follow-up rates in a multiethnic population. Design, Setting, and Participants: This population-based cohort study was conducted at a health maintenance organization in Hawaii. LCS program participants were identified using electronic medical records from January 1, 2015, to December 31, 2019. Study eligibility requirements included being aged 55 to 79 years, a 30 pack-year smoking history, a current smoker or having quit within the past 15 years, at least 5 years past any lung cancer diagnosis and treatment, and cancer free. Data analysis was performed from June 2019 to October 2020. Exposure: Eligible for LCS. Main Outcomes and Measures: Screening rates were analyzed by self-reported race and ethnicity and completion of a low-dose computed tomography (LDCT) test. Diagnostic follow-up results were based on the Lung Imaging Reporting and Data System (Lung-RADS) staging system. Results: A total of 1030 eligible LCS program members had an order placed; their mean (SD) age was 65.5 (5.8) years, and 633 (61%) were men. The largest racial and ethnic groups were non-Hispanic White (381 participants [37.0%]), Native Hawaiian or part Native Hawaiian (186 participants [18.1%]), and Japanese (146 participants [14.2%]). Men and Filipino, Chinese, Japanese, and non-Hispanic White individuals had a higher proportion of screen orders for LDCT compared with women and individuals of the other racial and ethnic groups. The overall LCS completion rate was 81% (838 participants). There was a 14% to 15% screening completion rate gap among groups. Asian individuals had the highest screening completion rate (266 participants [86%]) followed by Native Hawaiian (149 participants [80%]) and non-Hispanic White individuals (305 participants [80%]), Pacific Islander (50 participants [79%]) individuals, and individuals of other racial and ethnic groups (68 participants [77%]). Within Asian subgroups, Korean (31 participants [94%]) and Japanese (129 participants [88%]) individuals had the highest completion rates followed by Chinese individuals (28 participants [82%]) and Filipino individuals (78 participants [79%]). Of the 54 participants with Lung-RADS stage 3 disease, 93% (50 participants) completed a 6-month surveillance LDCT test; of 37 individuals with Lung-RADS stage 4 disease, 35 (97%) were followed-up for additional procedures. Conclusions and Relevance: This cohort study found racial and ethnic disparities in LCS completion rates after disaggregation of Native Hawaiian, Pacific Islander, and Asian individuals and their subgroups. These findings suggest that future research is needed to understand factors that may be associated with LCS completion and follow-up behaviors among these racial and ethnic groups.

Melioidosis-a disease of socioeconomic disadvantage.

BACKGROUND: There is growing recognition of the contribution of the social determinants of health to the burden of many infectious diseases. However, the relationship between socioeconomic status and the incidence and outcome of melioidosis is incompletely defined. METHODS: All residents of Far North Queensland, tropical Australia with culture-proven melioidosis between January 1998 and December 2020 were eligible for the study. Their demographics, comorbidities and socioeconomic status were correlated with their clinical course. Socioeconomic status was determined using the Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-economic Disadvantage score, a measure of socioeconomic disadvantage developed by the Australian Bureau of Statistics. Socioeconomic disadvantage was defined as residence in a region with a SEIFA score in the lowest decile in Australia. RESULTS: 321 eligible individuals were diagnosed with melioidosis during the study period, 174 (54.2%) identified as Indigenous Australians; 223/321 (69.5%) were bacteraemic, 85/321 (26.5%) required Intensive Care Unit (ICU) admission and 37/321 (11.5%) died. 156/321 (48.6%) were socioeconomically disadvantaged, compared with 56603/269002 (21.0%) of the local general population (p<0.001). Socioeconomically disadvantaged patients were younger, more likely to be female, Indigenous, diabetic or have renal disease. They were also more likely to die prior to hospital discharge (26/156 (16.7%) versus 11/165 (6.7%), p = 0.002) and to die at a younger age (median (IQR) age: 50 (38-68) versus 65 (59-81) years, p = 0.02). In multivariate analysis that included age, Indigenous status, the presence of bacteraemia, ICU admission and the year of hospitalisation, only socioeconomic disadvantage (odds ratio (OR) (95% confidence interval (CI)): 2.49 (1.16-5.35), p = 0.02) and ICU admission (OR (95% CI): 4.79 (2.33-9.86), p<0.001) were independently associated with death. CONCLUSION: Melioidosis is disease of socioeconomic disadvantage. A more holistic approach to the delivery of healthcare which addresses the social determinants of health is necessary to reduce the burden of this life-threatening disease.

The experiences of Aboriginal and Torres Strait Islander Bachelor of Midwifery students: An integrative literature review.

ISSUE: There is an underrepresentation of Aboriginal and Torres Strait Islander midwives across Australia and an inadequate number of graduating midwives to redress this. A major pillar for the Birthing on Country Model is maternity care workforce development. AIM: The purpose of this review is to examine the enablers and barriers that Aboriginal students experience while undertaking the Bachelor of Midwifery degree in Australia. METHODS: A search of the literature was undertaken through electronic databases. When only three papers were found looking at the experiences of Aboriginal midwifery students the search was broadened to include Aboriginal undergraduate health students. FINDINGS: The literature review reported a strong need for cultural safety in both the clinical and education systems. Students with access to cultural supports, relationships with Aboriginal mentors and academics and Aboriginal clinical placements felt empowered and were able to navigate the 'two worlds' in a meaningful way. DISCUSSION: This review highlights a significant gap in the literature. Despite the expanded search terms to include Aboriginal health students, a relatively narrow range of papers were found. Interestingly, the combined search revealed similar themes: kinship, personal factors, and cultural issues. CONCLUSION: Empowering and supporting Aboriginal Peoples to become midwives is essential. While systems and societies aim for cultural safety, this review shows there is still a way to go. Further research is essential to decolonise higher education and health care systems, and provide strong, well supported pathways for Aboriginal midwifery students.

Nutritional adequacy and the role of supplements in the diets of Indigenous Australian women during pregnancy.

OBJECTIVE: To determine sources of key nutrients contributing towards nutritional adequacy during pregnancy (fibre, calcium, iron, zinc and folate) in a cohort of women carrying an Indigenous child. DESIGN: Analysis of cross-sectional data from a prospective longitudinal cohort study that followed Indigenous women through pregnancy. SETTING: Women recruited via antenatal clinics in regional and remote locations in NSW, Australia as part of the Gomeroi gaaynggal project. PARTICIPANTS: One hundred and fifty-two pregnant Australian women who identified as Indigenous or carrying an Indigenous child. MEASUREMENTS AND FINDINGS: Measurement outcomes included demographic information, smoking status, anthropometrics (weight and height,), self-reported pre-pregnancy weight, health conditions and dietary information (24-hour food recall). Findings indicate the inadequate intake of key pregnancy nutrients in this cohort. Supplements contributed to the nutrient adequacy of the cohort with 53% reporting use. As expected, predominant sources of fibre were from core food groups, whereas calcium was attained from a range of sources including food and beverages, with small amounts from supplementation. Importantly, supplements contributed significant amounts of iron, zinc and folate. KEY CONCLUSIONS: There is limited literature on Indigenous Australian maternal nutrition. This study highlights the key dietary contributors of nutritional adequacy during pregnancy for the cohort and that supplementation may be considered a viable source of nutrients during pregnancy for these women. Few women met national nutrient recommendations. The findings present an opportunity to optimise nutrient intakes of Indigenous pregnant women. IMPLICATIONS FOR PRACTICE: Culturally appropriate targeted interventions to optimise dietary intakes of Indigenous Australian pregnant women is required. Collaborative support of health workers, Indigenous Australian communities, dietitians, and researchers to raise awareness of nutrition during pregnancy is imperative to achieving nutrient targets and optimising pregnancy outcomes. Targeted interventions provide positive opportunities to achieve improvements.

Mortality in sickle cell disease: A population-based study in an aboriginal community in the Gudalur Valley, Nilgiris, Tamil Nadu, India.

BACKGROUND: Sickle cell disease (SCD), the most common monogenic disorder, affects more than 300 000 births annually, with 44  000 in India. Although the clinical phenotype of SCD is considered to be milder in aboriginal populations in India, there is a paucity of data on outcomes. To determine the severity of SCD in this population, we studied mortality rates and causes of mortality in a longitudinal cohort of patients with SCD in a remote aboriginal community in India receiving community-based comprehensive care. PROCEDURES: Causes of death were analyzed in this cohort from January 2008 to December 2018. Details were collected from hospital records and in case of deaths at home by utilizing the WHO verbal autopsy questionnaire. RESULTS: The cohort consisted of 157 patients belonging to the Paniya, Betta Kurumba, Kattunyakan, and Mullu Kurumba tribes. During the study period, there were 22 deaths, all from the Paniya tribe. Twelve deaths (54.5%) occurred in the hospital and the remaining at home (45.5%), reflecting a crude mortality rate of 140 per 1000 population. Twenty-five percent of deaths occurred in the 6-18 age group. There were no deaths in the 0-5 age group. The median age of death was 25 years, which was 30 years less than in the non-SCD aboriginal population. The leading causes of death were acute chest syndrome, anemia, and sepsis among the SCD patients and stroke and suicides in the non-SCD aboriginal population. CONCLUSION: SCD is a severe disease among the Gudalur Valley's aboriginal population with a significant risk of premature mortality.

Quantitative evaluation of an outreach case management model of care for urban Aboriginal and Torres Strait Islander adults living with complex chronic disease: a longitudinal study.

BACKGROUND: Chronic diseases are the leading contributor to the excess morbidity and mortality burden experienced by Aboriginal and Torres Strait Islander (hereafter, respectfully, Indigenous) people, compared to their non-Indigenous counterparts. The Home-based Outreach case Management of chronic disease Exploratory (HOME) Study provided person-centred, multidisciplinary care for Indigenous people with chronic disease. This model of care, aligned to Indigenous peoples' conceptions of health and wellbeing, was integrated within an urban Indigenous primary health care service. We aimed to determine the impact of this model of care on participants' health and wellbeing at 12 months. METHODS: HOME Study participants were Indigenous, regular patients of the primary health care service, with a diagnosis of at least one chronic disease, and complex health and social care needs. Data were collected directly from participants and from their medical records at baseline, and 3, 6 and 12 months thereafter. Variables included self-rated health status, depression, utilisation of health services, and key clinical outcomes. Participants' baseline characteristics were described using frequencies and percentages. Generalized estimating equation (GEE) models were employed to evaluate participant attrition and changes in outcome measures over time. RESULTS: 60 participants were enrolled into the study and 37 (62%) completed the 12-month assessment. After receiving outreach case management for 12 months, 73% of participants had good, very good or excellent self-rated health status compared with 33% at baseline (p < 0.001) and 19% of participants had depression compared with 44% at baseline (p = 0.03). Significant increases in appointments with allied health professionals (p < 0.001) and medical specialists other than general practitioners (p = 0.001) were observed at 12-months compared with baseline rates. Mean systolic blood pressure decreased over time (p = 0.02), but there were no significant changes in mean HbA1c, body mass index, or diastolic blood pressure. CONCLUSIONS: The HOME Study model of care was predicated on a holistic conception of health and aimed to address participants' health and social care needs. The positive changes in self-rated health and rates of depression evinced that this aim was met, and that participants received the necessary care to support and improve their health and wellbeing.

Inequity in one-year mortality after first myocardial infarction in Maori and Pacific patients: how much is associated with differences in modifiable clinical risk factors? (ANZACS-QI 49).

AIMS: Ischaemic heart disease (IHD) mortality rates after myocardial infarction (MI) are higher in Maori and Pacific compared to European people. The reasons for these differences are complex and incompletely understood. Our aim was to use a contemporary real-world national cohort of patients presenting with their first MI to better understand the extent to which differences in the clinical presentation, cardiovascular (CVD) risk factors, comorbidity and in-hospital treatment explain the mortality outcomes for Maori and Pacific peoples. METHODS: New Zealand residents (≥20 years old) hospitalised with their first MI (2014-2017), and who underwent coronary angiography, were identified from the All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) registry. All-cause mortality up to one year after the index admission date was obtained by linkage to the national mortality database. RESULTS: There were 17,404 patients with a first ever MI. European/other comprised 76% of the population, Maori 11.5%, Pacific 5.1%, Indian 4.3% and Other Asian 2.9%. Over half (55%) of Maori, Pacific and Indian patients were admitted with their first MI before age 60 years, compared with 29% of European/other patients. Maori and Pacific patients had a higher burden of traditional and non-traditional cardiovascular risk factors, and despite being younger, were more likely to present with heart failure and, together with Indian peoples, advanced coronary disease at presentation with first MI. After adjustment for age and sex, Maori and Pacific, but not Indian or Other Asian patients had significantly higher all-cause mortality at one year compared with the European/other reference group (HR 2.55 (95% CI 2.12-3.07), HR 2.98 (95% CI 2.34-3.81) for Maori and Pacific respectively). When further adjusted for differences in clinical presentation, clinical history and cardiovascular risk factors, the excess mortality risk for Maori and Pacific patients was reduced substantially, but a differential persisted (HR 1.77 (95% CI 1.44-2.19), HR 1.42 (95% CI 1.07-1.83)) which was not further reduced by adjustment for differences in in-hospital management and discharge medications. CONCLUSION: In New Zealand patients after their first MI there is a three-fold variation in one-year mortality based on ethnicity. At least half of the inequity in outcomes for Maori, and three-quarters for Pacific people, is associated with differences in preventable or modifiable clinical factors present at, or prior to, presentation.

Parents' and carers' views on factors contributing to the health and wellbeing of urban Aboriginal children.

OBJECTIVE: To identify and describe caregiver perspectives on factors important for the health and wellbeing of urban Aboriginal children. METHODS: Caregivers of Aboriginal children participating in the Study of Environment on Aboriginal Resilience and Child Health (SEARCH) were asked to describe the single most important factor that would help their children to be healthy and well. Responses were analysed using thematic and content analysis. RESULTS: Of the 626 carers in SEARCH, 425 (68%) provided a response. We identified 13 factors related to: loving family relationships, culturally competent healthcare, food security, active living, community services, education, social and emotional connectedness, safety, breaking cycles of disadvantage, housing availability and affordability, positive Aboriginal role models, strong culture, and carer wellbeing. CONCLUSIONS: Aligning with holistic concepts of health, caregivers believe that a broad range of child, family and environmental-level factors are needed to ensure the health and wellbeing of Aboriginal children. Implications for public health: This study highlights the importance of providing public health initiatives that enable equal access to the social determinants of health for carers of Aboriginal children. Affordable and adequate housing, food security, culturally appropriate healthcare, and family and community connectedness remain critical areas for targeted initiatives.

Attitudes towards cannabis and cannabis law change in a New Zealand birth cohort.

AIMS: Personal cannabis use is common across New Zealand, and an upcoming referendum will enable the public to vote on whether this should be legalised. The present research aimed to examine the attitudes of midlife New Zealand adults on cannabis use and legalisation, and to identify potential predictors of those attitudes. METHODS: At age 40, 899 participants drawn from the Christchurch Health and Development Study were interviewed about the perceived harmfulness of cannabis use, opinions on legalisation for recreational use and supply, and the use of cannabis for medicinal purposes. In addition, a range of potential predictors of legislative attitudes were examined. RESULTS: We identified a wide range of attitudes across the cohort, however the majority tended to hold a neutral view. More than 80% of the cohort expressed support for medicinal cannabis, while 47.8% supported decriminalisation, and 26.8% expressed support for legalisation for recreational use. The strongest predictors of support for legalisation were prior use of cannabis and other drugs, while additional positive predictors included a history of depression, Maori ancestry, parental drug use, novelty seeking and higher educational attainment. Predictors of more negative attitudes were also identified, and included female gender and having dependent children. CONCLUSIONS: These findings provide insight into cannabis-related views within the New Zealand context, and may help to predict voting behaviour during the 2020 Cannabis Referendum.

Influences on drinking choices among Indigenous and non-Indigenous pregnant women in Australia: A qualitative study.

Despite women's awareness that drinking alcohol in pregnancy can lead to lifelong disabilities in a child, it appears that an awareness alone does not discourage some pregnant women from drinking. To explore influences on pregnant women's choices around alcohol use, we conducted interviews and group discussions with 14 Indigenous Australian and 14 non-Indigenous pregnant women attending antenatal care in a range of socioeconomic settings. Inductive content analysis identified five main influences on pregnant women's alcohol use: the level and detail of women's understanding of harm; women's information sources on alcohol use in pregnancy; how this information influenced their choices; how women conceptualised their pregnancy; and whether the social and cultural environment supported abstinence. Results provide insight into how Indigenous Australian and non-Indigenous pregnant women understand and conceptualise the harms from drinking alcohol when making drinking choices, including how their social and cultural environments impact their ability to abstain. Strategies for behaviour change need to: correct misinformation about supposed 'safe' timing, quantity and types of alcohol; develop a more accurate perception of Fetal Alcohol Spectrum Disorder; reframe messages about harm to messages about optimising the child's health and cognitive outcomes; and develop a holistic approach encompassing women's social and cultural context.

An economic evaluation of the All New Zealand Acute Coronary Syndrome Quality Improvement Registry programme-subanalyses for Maori (ANZACS-QI 42).

AIMS: To evaluate the clinical and cost impacts of the All New Zealand Acute Coronary Syndrome Quality Improvement programme (ANZACS-QI) specifically for Maori with acute coronary syndrome (ACS). METHODS: Decision analytic Markov models were used to estimate the effectiveness and costs of the ANZACS-QI programme over four years of full coverage (2013 to 2016), against a hypothetical scenario in which the registry did not exist. The estimated return on investment (ROI) and incremental cost-effectiveness ratios (ICERs) are reported. RESULTS: The ROI ratio for the ANZACS-QI programme for Maori over the four-year period of full coverage was 1.51; that is, every dollar spent on the programme resulted in a return of NZD $1.51. The estimated ICER was NZD $114,786 per year of life saved (YoLS) over a one-year time horizon, but extending the benefits accrued to five years reduced the ICER to NZD $20,173 per YoLS. CONCLUSIONS: The ANZACS-QI programme represents a sound investment for improving outcomes in the setting of ACS for Maori in New Zealand. Using highly conservative assumptions, the programme would be cost-saving based on an annual ROI ratio of 1.5.

An examination of the cross-sectional geometrical properties of the long bone diaphyses of Holocene foragers from Roonka, South Australia.

OBJECTIVES: This study examines long bone diaphyseal rigidity and shape of hunter-gatherers at Roonka to make inferences about subsistence strategies and mobility of inhabitants of semi-arid southeastern Australia. Roonka is a cemetery site adjacent to the Lower Murray River, which contains over 200 individuals buried throughout the Holocene. Archaeological evidence indicates that populations living near this river corridor employed mobile, risk averse foraging strategies. METHODS: This prediction of lifestyle was tested by comparing the cross-sectional geometric properties of the humerus, radius, ulna, femur, tibia, and fibula of individuals from Roonka to samples of varying subsistence strategies. Bilateral asymmetry of the upper limb bones was also examined. RESULTS: Roonka males and females have moderately high lower limb diaphyseal rigidity and shape. In the upper limb, females have low rigidity and bilateral asymmetry while males have moderately high rigidity and bilateral asymmetry. This pattern is similar to other foraging groups from Australia and southern Africa that have behaviorally adapted to arid and semi-arid environments. DISCUSSION: Lower limb results suggest that populations in the Lower Murray River Valley had relatively elevated foraging mobility. Upper limb rigidity and bilateral asymmetry indicate a sexual division of labor at Roonka. Females resemble other samples that had mixed subsistence strategies that involved hunting, gathering, and processing tasks. Males display a pattern similar to groups that preferentially hunted large game, but that supplemented this source with smaller game and riverine resources.

Reaching out to reduce health inequities for Maori youth.

AIM: This paper describes an initiative facilitating comprehensive assessment and delivery of brief interventions for Maori youth in Northland, New Zealand. BACKGROUND: The population in Northland is predominantly Maori and is one of New Zealand's most deprived populations. Maori youth have the highest youth suicide rate in the developed world and elevated numbers of youth displaying mental health issues and/or risk behaviours are of grave national concern. Like Indigenous peoples worldwide, inequities persist for Maori youth accessing and engaging with healthcare services. DESCRIPTION: Taking services out to Maori youth in remote and isolated areas, Northland's youth specialist nurses are reducing some barriers to accessing health care. The youth version of the Case-finding and Help Assessment Tool is a New Zealand-developed, e-screening tool for youth psychosocial issues, facilitating comprehensive assessment and brief intervention delivery. DISCUSSION: Early detection of, and timely intervention for, mental health and risk behaviours can significantly improve health outcomes in youth. However, for this to happen barriers preventing youth from accessing appropriate care need to be overcome. CONCLUSION: Youth specialist nurses could improve access to care for youth from ethnic minorities, rural and isolated regions, and areas of high deprivation without overwhelming the medical profession. IMPLICATIONS FOR NURSING POLICY: Specialist nurses are trained and empowered to practice at the top of their scope. With general practitioner oversight and standing order sign off specialist nurses can work autonomously to improve access to health services, without increasing the workload of doctors. IMPLICATIONS FOR NURSING PRACTICE: Encouraging continuous self-reflection of the nurse's effectiveness in meeting patient needs, holistically and culturally, facilitates the provision of accessible care that is patient-centred and culturally safe.

Sugar-sweetened beverage consumption among Indigenous Australian children aged 0-3 years and association with sociodemographic, life circumstances and health factors.

OBJECTIVE: To explore beverage intake and associations between sugar-sweetened beverage (SSB) intake and sociodemographic, life circumstances, health and well-being factors in a national cohort of Indigenous children. DESIGN: We calculated prevalence ratios for any SSB consumption across exposures, using multilevel Poisson regression (robust variance), adjusted for age group and remoteness. A key informant focus group contextualised these exploratory findings. SETTING: Diverse settings across Australia. PARTICIPANTS: Families of Indigenous children aged 0-3 years, in the Longitudinal Study of Indigenous Children. RESULTS: Half (50·7 %, n 473/933) of children had ever consumed SSB at survey, increasing from 29·3 % of 0-12-month-olds to 65·7 % of 18-36-month-olds. SSB consumption prevalence was significantly lower in urban and regional v. remote areas, and in families experiencing socio-economic advantage (area-level advantage, caregiver employed, financial security), better life circumstances (caregiver social support, limited exposure to stressors) and caregiver well-being (non-smoking, social and emotional well-being, physical health). SSB consumption prevalence was significantly lower among those engaged with health services (adequate health-service access, regular prenatal check-ups), except SSB consumption prevalence was higher among those who received home visits from an Aboriginal Health Worker compared with no home visits. Key informants highlighted the role of water quality/safety on SSB consumption. CONCLUSIONS: A substantial proportion of Indigenous children in this sample consumed SSB from an early age. Health provider information needs to be relevant to the context of families' lives. Health system strategies must be paired with upstream strategies, such as holistic support programmes for families, reducing racism and improving water quality.

Holistic primary health care for Aboriginal and Torres Strait Islander prisoners: exploring the role of Aboriginal Community Controlled Health Organisations.

OBJECTIVE: Aboriginal and Torres Strait Islander Community Controlled Health Organisations (ACCHOs) have been identified as having an important role in improving the health and wellbeing of individuals in prison; however, a lack of information exists on how to strengthen this role. This paper explores the experiences of ACCHO staff in primary health care to individuals inside or leaving prison. METHODS: Nineteen staff from four ACCHOs were interviewed. ACCHO selection was informed by proximity to prisons, town size and/or Local Government Area offending rates. Thematic analysis of the interviews was undertaken. RESULTS: While most ACCHOs had delivered post-release programs, primary health care delivery to prisoners was limited. Three themes emerged: i) a lack of access to prisoners; ii) limited funding to provide services to prisoners; and iii) the need for a team approach to primary health care delivery. CONCLUSION: A holistic model of care underpinned by a reliable funding model (including access to certain Medicare items) and consistent access to prisoners could strengthen ACCHOs' role in primary health care delivery to people inside or leaving prison. Implications for public health: ACCHOs have an important role to play in the delivery of primary health care to prisoners. Existing models of care for prisoners should be examined to explore how this can occur.

Mate wareware: Understanding 'dementia' from a Maori perspective.

AIM: To investigate Maori (Indigenous people of Aotearoa New Zealand) understandings of dementia, its causes, and ways to manage a whanau (extended family) member with dementia. METHOD: We undertook kaupapa Maori research (Maori informed research) with 223 kaumatua (Maori elders) who participated in 17 focus groups across seven study regions throughout Aotearoa New Zealand and eight whanau from the Waikato region. We audio recorded all interviews, transcribed them and then coded and categorised the data into themes. RESULTS: Mate wareware (becoming forgetful and unwell) ('dementia') affects the wairua (spiritual dimension) of Maori. The findings elucidate Maori understandings of the causes of mate wareware, and the role of aroha (love, compassion) and manaakitanga (hospitality, kindness, generosity, support, caring) involved in caregiving for whanau living with mate wareware. Participants perceived cultural activities acted as protective factors that optimised a person's functioning within their whanau and community. CONCLUSION: Whanau are crucial for the care of a kaumatua with mate wareware, along with promoting healthy wairua for all. Whanau urgently need information to assist with their knowledge building and empowerment to meet the needs of a member affected by mate wareware. This requires collaborative healthcare practice and practitioners accessing the necessary matauranga Maori (Maori knowledge) to provide culturally appropriate and comprehensive care for whanau.

Folic acid deficiency declined substantially after introduction of the mandatory fortification programme in Queensland, Australia: a secondary health data analysis.

OBJECTIVE: To investigate the prevalence of folic acid deficiency in Queensland-wide data of routine laboratory measurements, especially in high-risk sub-populations. DESIGN: Secondary health data analysis. SETTING: Analysis of routine folic acid tests conducted by Pathology Queensland (AUSLAB). PARTICIPANTS: Female and male persons aged 0-117 years with routine folic acid testing between 1 January 2004 and 31 December 2015. If repeat tests on the same person were conducted, only the initial test was analysed (n 291 908). RESULTS: Overall the prevalence of folic acid deficiency declined from 7·5 % before (2004-2008) to 1·1 % after mandatory folic acid fortification (2010-2015; P < 0·001) reflecting a relative reduction of 85 %. Levels of erythrocyte folate increased significantly from a median (interquartile range) of 820 (580-1180) nmol/l in 2008 before fortification to 1020 (780-1350) nmol/l in 2010 (P < 0·001) after fortification. The prevalence of folic acid deficiency in the Indigenous population (14 792 samples) declined by 93 % (17·4 v. 1·3 %; P < 0·001); and by 84 % in non-Indigenous residents (7·0 v. 1·1 %; P < 0·001). In a logistic regression model the observed decrease of folic acid deficiency between 2008 and 2010 was found independent of gender, age and ethnicity (ORcrude = 0·20; 95 % CI 0·18, 0·23; P < 0·001; ORadjusted = 0·21; 95 % CI 0·18, 0·23; P < 0·001). CONCLUSIONS: While voluntary folic acid fortification, introduced in 1995, failed especially in high-risk subgroups, the 2009 mandatory folic acid fortification programme coincided with a substantial decrease of folic acid deficiency in the entire population.

Understanding physical activity patterns among rural Aboriginal and non-Aboriginal young people.

INTRODUCTION: Physical activity across the lifespan is essential to good health but participation rates are generally lower in rural areas and among Aboriginal Australians. Declines in moderate-to-vigorous physical activity (MVPA) commence before adolescence but descriptive epidemiology of patterns of physical activity among Aboriginal children is limited. MVPA variation by season, setting and type at two time points among rural Aboriginal and non-Aboriginal Australian children was examined. METHODS: Children aged 10-14 years in 38 schools in two rural New South Wales towns during 2007-2008 (T1) and 2011-2012 (T2) self-reported time spent engaged in MVPA for different types, settings and seasons, totalling 14 components: organised, non-organised, club, school, travel to/from school, after school and weekend - in both summer and winter. Linear mixed models assessed MVPA mean minutes and 95% confidence intervals for Aboriginal and non-Aboriginal children and between-group mean differences over time. RESULTS: A total of 1545 children (246 Aboriginal) at T1 and 923 children (240 Aboriginal) at T2 provided data. Overall MVPA, travel to/from school (summer and winter) and after-school activity (winter) declined over time in both groups (p≤0.005). Significant declines occurred in non-organised, school (summer and winter) and organised (winter) activity among Aboriginal children only. There were differences according to Aboriginality from T1 to T2 for school (summer and winter; p<0.001), weekend (summer; p=0.02) and winter organised (winter; p<0.001) activity . CONCLUSIONS: While overall physical activity declines occurred between 2007-208 (T1) and 2011-2012 (T2) in both Aboriginal and non-Aboriginal rural-dwelling children, declines in particular components of physical activity were greater among Aboriginal compared to non-Aboriginal children. A multi-strategy, holistic approach to increase physical activity during the critical time of adolescence is necessary.

Medicinal plant use in two Tiwi Island communities: a qualitative research study.

BACKGROUND: Traditional medicinal plants are still used today in many Aboriginal communities across Australia. Our research focused on the contemporary use of such plants in the two communities within the Tiwi Islands, Wurrumiyanga and Pirlangimpi. METHODS: This qualitative research project performed a video ethnography, community interviews, and a trial intervention to better understand the extent to which these plants are still used throughout the community and how they may be used more in the future. RESULTS: We found that several plants are still used predominantly as medicinal washes to treat skin disorders and/or as a tea to treat congestion associated with cold and flu. Those plants that are commonly used are found near to the community in large amounts and are recognized as being both safe and effective. CONCLUSIONS: Within the community, it is the elder women who remain most knowledgeable about these plants and continue to make them for their families. However, there are many families who no longer know how to make these traditional medicines though they express a desire to use them. Therefore, it would be beneficial to have a central location or method to produce traditional medicine for the community-a bush pharmacy.

Exploring Aboriginal aged care residents' cultural and spiritual needs in South Australia.

BACKGROUND: Attention to culture and its impact on health care can improve the quality of care given, add to our understanding of health care among culturally diverse populations, and encourage a more holistic approach to health care within general care. Connection to culture is important to Aboriginal peoples, and integrating Aboriginal culture into general care in residential aged care facilities may contribute to improving care delivery and outcomes for residents. The literature to date revealed a lack of understanding of the capacity of residential aged care and the health practices of carers in relation to providing cultural care for Aboriginal people. This study aimed to explore how cultural care needs are maintained for Aboriginal residents from their own and their carers' perspectives. METHODS: Applying an Aboriginal centered research method, an Interpretive Descriptive Approach was used as a theoretical framework to explore data in this study. Semi structured audio-recorded interviews were conducted. An additional file provides a complete description of the interview questions used as a guide for the study [see Additional file 1]. Three Residential Aged Care Centres, in South Australia were used i.e., two rural from centres and one urban metropolitan centre. Seven Aboriginal residents and 19 carers participated in interviews. Data was transcribed and an interpretive analysis was employed to code the transcribed data for themes and sub-themes. The study was guided by an Aboriginal community advisory group with an aim to work under the principle of reciprocity; giving back to the communities, participants and those where the research results may have been relevant. RESULTS: Three themes emerged from the views of the residents and carers: (i) lack of resources and funding; (ii) care practice; and (iii) marginalisation of Aboriginal culture within aged care facilities. CONCLUSION: The findings suggest that carers and residents believe cultural inclusion in general care practices may enrich Aboriginal residents' daily life, health and well-being in residential aged care facilities. This study may provide carers, aged care centre managers and policy makers with information on the need of resources, funding, organised care plan and management, and cultural competency of carers to be considered to improve Aboriginal aged care protocols for integrating cultural care into practice.
