Kulay Kalingka, a national cohort study of Aboriginal and Torres Strait Islander peoples' cancer experiences: a study protocol.

Introduction: Aboriginal and Torres Strait Islander peoples are the First Peoples of Australia. Since settler colonisation, Aboriginal and Torres Strait Islander peoples have experienced disparities in health outcomes, including cancer, when compared with non-Indigenous Australians, including higher cancer incidence and mortality rates, and lower participation in cancer screening programmes. Data to monitor and improve outcomes are limited.

Who responds? An examination of response rates to a national postal survey of Aboriginal and Torres Strait Islander adults, 2018-2019.

Background: Evidence on the effectiveness of postal recruitment methods for Indigenous peoples is lacking. Mayi Kuwayu, the National Study of Aboriginal and Torres Strait Islander Wellbeing, uses multi-staged sampling. We aimed to test postal surveys as a primary recruitment method, analysing preliminary response rate data to inform the Study's ongoing sampling approach.

'Telling our story... Creating our own history': caregivers' reasons for participating in an Australian longitudinal study of Indigenous children.

Background: Improving the wellbeing of Indigenous populations is an international priority. Robust research conducted with Aboriginal and Torres Strait Islander peoples is key to developing programs and policies to improve health and wellbeing. This paper aims to quantify the extent of participation in a national longitudinal study of Aboriginal and Torres Strait Islander (Indigenous Australian) children, and to understand the reasons why caregivers participate in the study.

Obesity and its association with sociodemographic factors, health behaviours and health status among Aboriginal and non-Aboriginal adults in New South Wales, Australia.

Background: High body mass index (BMI) is the second leading contributor to Australia's burden of disease and is particularly prevalent among Aboriginal peoples. This paper aims to provide insight into factors relating to obesity among Aboriginal adults and Aboriginal-non-Aboriginal differences.

Methods: Cross-sectional analysis of data from the 45 and Up Study, comparing obesity (BMI ≥30 kg/m) prevalence and risk factors among 1515 Aboriginal and 213 301 non-Aboriginal adults in New South Wales.

Body mass index trajectories of Indigenous Australian children and relation to screen time, diet, and demographic factors.

Objective: Limited cross-sectional data indicate elevated overweight/obesity prevalence among Indigenous versus non-Indigenous Australian children. This study aims to quantify body mass index (BMI) trajectories among Indigenous Australian children aged 3-6 and 6-9 years and to identify factors associated with the development of overweight/obesity.

Methods: Three-year BMI change was examined in up to 1,157 children in the national Longitudinal Study of Indigenous Children.

Understanding barriers to fruit and vegetable intake in the Australian Longitudinal Study of Indigenous Children: a mixed-methods approach.

Objective: To identify barriers to fruit and vegetable intake for Indigenous Australian children and quantify factors related to these barriers, to help understand why children do not meet recommendations for fruit and vegetable intake.

Design: We examined factors related to carer-reported barriers using multilevel Poisson models (robust variance); a key informant focus group guided our interpretation of findings.

Setting: Eleven diverse sites across Australia.
