Improving cardiometabolic risk factors in Aboriginal and Torres Strait Islander people in northeast Arnhem Land: single arm trial of a co‐designed dietary and lifestyle program
Bibliographic record
Abstract
Abstract Objective To evaluate the impact of a 4‐month dietary and lifestyle program co‐designed and led by Aboriginal and Torres Strait Islander people on weight and metabolic markers, diet, and physical activity in overweight and obese adults in a remote Indigenous community. Study design Single arm, pre–post intervention study. Setting, participants Adult residents (18–65 years) of a remote Northern Territory community with body mass index (BMI) values of at least 25 kg/m 2 or waist circumferences exceeding 94 cm (men) or 80 cm (women). Intervention Hope for Health, a culturally sensitive 4‐month program supporting self‐managed health improvement based on dietary and lifestyle change, 1 August to 30 November 2022. Main outcome measures Weight loss of at least 5%; changes in BMI, waist circumference, other metabolic markers (blood pressure, biomarkers of metabolic health and inflammation), diet, and physical activity; participant perceptions of the program. Results We assessed outcomes for 55 participants who completed weight assessments at both baseline and program end (mean age, 42.5 years [standard deviation, 10.1 years]; 36 women [65%]). Forty participants lost and 15 gained weight; overall mean weight loss was 1.5 kg (95% confidence interval [CI], 0.5–2.4 kg), and ten participants (18%; 95% CI, 9–31%) achieved at least 5% weight reduction. The mean change in BMI (53 participants) was –0.60 kg/m 2 (95% CI, –0.93 to –0.27 kg/m 2 ), in waist circumference (53 participants) –3.2 cm (95% CI, –4.7 to –1.7 cm), and in low‐density lipoprotein cholesterol level (37 participants) –0.28 mmol/L (95% CI, –0.47 to –0.08 mmol/L); the relative decline in the HbA 1c level geometric mean (50 participants) was 11% (95% CI, 6–15%). The intake of breads and cereals (median change, –1.5 [95% CI, –2.0 to –1.0] serves/day) and sugar‐sweetened beverages (–0.6 [95% CI, –1.4 to –0.1] serves/day) declined; the amount of moderate and vigorous physical activity increased by a median of 103 min/day (95% CI, 74–136 min/day; 19 participants). The program focus on integrating healthy bodies and networks of kin, healthy governance, vibrant language and ceremony, and a healthy environment were seen as central to its value and benefit. Conclusions Community appreciation of the program and the improvements in cardiometabolic risk factors are encouraging, providing an example of a culturally sensitive, co‐designed initiative led by Indigenous people for reducing the prevalence of chronic disease in remote areas.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
