Antioxidant biomarkers and cardiometabolic risk markers in an Aboriginal community in remote Australia: A cross-sectional study
Objective: High-quality diets, characterised by nutrient-rich foods, are one of the foundations for health and well-being. Indicators of diet quality, antioxidants, are associated with protection against cardiometabolic diseases. The current study explores relationships between plasma antioxidants and cardiometabolic risk among Aboriginal people in Australia. Design: As part of a community-driven health promotion programme, we conducted a cross-s…
Associations between Community Environmental-Level Factors and Diet Quality in Geographically Isolated Australian Communities
Remote Indigenous Australians experience disproportionately poor cardio-metabolic health, which is largely underpinned by adverse dietary intake related to social determinants. Little evidence exists about the community environmental-level factors that shape diet quality in this geographically isolated population group. This study aimed to explore the modifiable environmental-level factors associated with the features of dietary intake that under…
Health-Promoting Food Pricing Policies and Decision-Making in Very Remote Aboriginal and Torres Strait Islander Community Stores in Australia
Aboriginal and Torres Strait Islander people living in remote communities in Australia experience a disproportionate burden of diet-related chronic disease. This occurs in an environment where the cost of store-purchased food is high and cash incomes are low, factors that affect both food insecurity and health outcomes. Aboriginal and Torres Strait Islander storeowners and the retailers who work with them implement local policies with the aim of …
Fluctuations in money availability within an income cycle impacts diet quality of remote Indigenous Australians
Objective To consider the plausible nutritional impacts of fluctuations in money availability within an income cycle for remote Indigenous Australians. Design Community-level dietary intake (energy, micro/macronutrients) and expenditure on foods and beverages (F&B) were estimated over one year for three remote Indigenous Australian communities (Northern Territory, Australia) using monthly F&B transaction data. F&B that were likely to be consumed …
Chronic kidney disease and socio-economic status: A cross sectional study
Objective : This cross-sectional study investigated the relationship between individual-level markers of disadvantage, renal function and cardio-metabolic risk within an Indigenous population characterised by a heavy burden of chronic kidney disease and disadvantage. Design : Using data from 20 Indigenous communities across Australia, an aggregate socio-economic status (SES) score was created from individual-level socio-economic variables reporte…
Dietary intervention for people with mental illness in South Australia
BACKGROUND: People with serious mental illness (SMI) have a 25-30 year lower life expectancy than the general population due largely to cardiovascular disease (CVD). Mediterranean diet can reduce CVD risk and repeat events by 30-70%. We conducted a pilot feasibility study (HELFIMED) with people who have SMI residing within a Community Rehabilitation Centre in South Australia, aimed at improving participants' diets according to Mediterranean diet …
Nutritional predictors of successful chronic disease prevention for a community cohort in Central Australia
Objective To investigate biomarkers of nutrition associated with chronic disease absence for an Aboriginal cohort. Design 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 bio…

Psychological distress and self‐rated oral health among a convenience sample of I ndigenous A ustralians
Poor self-rated oral health and high levels of psychological distress were both highly frequent among this vulnerable population. Psychological distress was significantly associated with poor self-rated oral health after adjustment for confounding
Factors Influencing Food Choice in an Australian Aboriginal Community
We explored with Aboriginal adults living in a remote Australian community the social context of food choice and factors perceived to shape food choice. An ethnographic approach of prolonged community engagement over 3 years was augmented by interviews. Our findings revealed that knowledge, health, and resources supporting food choice were considered "out of balance," and this imbalance was seen to manifest in a Western-imposed diet lacking varie…
Use of point-of-sale data to assess food and nutrient quality in remote stores
Objective To examine the feasibility of using point-of-sale data to assess dietary quality of food sales in remote stores. Design A multi-site cross-sectional assessment of food and nutrient composition of food sales. Point-of-sale data were linked to Australian Food and Nutrient Data and compared across study sites and with nutrient requirements. Setting Remote Aboriginal Australia. Subject Six stores. Results Point-of-sale data were readily ava…
Hypertriglyceridemic waist and newly-diagnosed diabetes among remote-dwelling Indigenous Australians
HTgW has a high prevalence and is associated with newly-diagnosed diabetes in Indigenous people, particularly those with BMI <22 kg/m(2), whom clinicians might not normally consider for screening
Plasma carotenoids are associated with socioeconomic status in an urban Indigenous population: An observational study
Even within urban Indigenous Australians, higher SES was associated with higher concentrations of plasma carotenoids. Low plasma carotenoids have been linked with poor health outcomes; increasing accessibility of fruit and vegetables, as well as reducing smoking rates could increase concentrations and otherwise improve health, but our results suggest there may be additional factors contributing to lower carotenoid concentrations in Indigenous Aus…

High rates of albuminuria but not of low eGFR in Urban Indigenous Australians: The DRUID Study
Given the significant excess of ESKD observed in Indigenous versus non-Indigenous Australians, these findings could suggest either: albuminuria may be a better prognostic marker of kidney disease than low eGFR; that eGFR equations may be inaccurate in the Indigenous population; a less marked differential between Indigenous and non-Indigenous Australians for ESKD rates in urban compared to remote regions; or that differences in the pathophysiology…
Study Protocol - Accurate assessment of kidney function in Indigenous Australians: Aims and methods of the eGFR Study
We have successfully managed several operational challenges within this multi-centre complex clinical research project performed across remote North, Western and Central Australia. It seems unlikely that a single correction factor (similar to that for African-Americans) to the equation for estimated glomerular filtration rate will prove appropriate or practical for Indigenous Australians. However, it may be that a modification of the equation in …
Abdominal obesity and other risk factors largely explain the high CRP in Indigenous Australians relative to the general population, but not gender differences: A cross-sectional study
High concentrations of CRP in Indigenous participants were largely explained by other risk factors, in particular abdominal obesity. Irrespective of its independence as a risk factor, or its aetiological association with coronary heart disease (CHD), the high CRP levels in urban Indigenous women are likely to reflect increased vascular and metabolic risk. The significance of elevated CRP in Indigenous Australians should be investigated in future …
Evaluation of an FFQ for assessment of antioxidant intake using plasma biomarkers in an ethnically diverse population
Objective To evaluate FFQ estimates of dietary intake of individual antioxidants, fruit and vegetables in comparison to plasma concentrations of each antioxidant, and to determine which individual foods are associated with plasma antioxidant concentrations. Design Dietary (α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin, lycopene, retinol, and vitamin E) intakes over 12 months were estimated from a 121-item FFQ. Correlation coefficient…

Socioeconomic status and diabetes among urban Indigenous Australians aged 15–64 years in the DRUID study
The relationship between SES and diabetes among Indigenous Australians in this study is consistent with the patterns observed in developed countries, rather than those in some developing countries
Mastery, perceived stress and health-related behaviour in northeast Arnhem Land: A cross-sectional study
Consistent with previous research, this study provides additional support for a link between mastery and health-related behaviour, and extends evidence of this association to a remote Indigenous population. Mastery's association with perceived stress, its age-specific association with health behaviour, and findings of low mastery amongst young men, highlights a need for life course research accounting for contextual factors affecting Indigenous p…
Study Protocol – Diabetes and related conditions in urban Indigenous people in the Darwin, Australia region: Aims, methods and participation in the DRUID Study
Despite lower than anticipated recruitment, this is, to our knowledge, the largest study ever conducted on the health of Indigenous Australians living in urban areas, a group which comprises the majority of Australia's Indigenous population but about whose health and wellbeing relatively little is known. The study is well-placed to provide new information that can be used by policy makers and service providers to improve the delivery of services …
Evaluation of brief dietary questions to estimate vegetable and fruit consumption – using serum carotenoids and red-cell folate
Objective To evaluate responses to self-administered brief questions regarding consumption of vegetables and fruit by comparison with blood levels of serum carotenoids and red-cell folate. Design A cross-sectional study in which participants reported their usual intake of fruit and vegetables in servings per day, and serum levels of five carotenoids (α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin and lycopene) and red-cell folate were…
Measuring dietary intake in remote australian aboriginal communities
This paper reports a comparison of the practicality, acceptability and face validity of five dietary intake methods in two remote Australian Aboriginal communities: weighed dietary intake, 24‐hour recall, ‘store‐turnover’, diet history and food frequency methods. The methods used to measure individual dietary intake were poorly accepted by the communities. Quantitative data were obtained only from the first three methods. The 24‐hour recall metho…
Part one: Some studies on the relationship between Urban living and diabetes in a group of Australian Aborigines
In an attempt to understand the reasons for the high incidence of diabetes among Australian Aborigines when they urbanise, we measured a number of metabolic parameters in a group of Aborigines from the Kimberley region of northwest Australia three months after they reverted temporarily to their traditional hunter‐gatherer lifestyle, and then again three months after they returned to urban.life. These Aborigines had an abnormally high insulin resp…
