Lifestyle interventions for type 2 diabetes prevention in children and adolescents of African descent in OECD countries: a systematic review protocol
Bibliographic record
Abstract
OBJECTIVES: The objectives of this review are to investigate the effectiveness of lifestyle interventions for type 2 diabetes prevention in children and adolescents of African descent in the Organisation for Economic Co-operation and Development (OECD) member countries and to attempt to ascertain what aspects of these interventions are most effective in this population. INTRODUCTION: Lifestyle interventions have been shown to prevent or delay the onset of type 2 diabetes;however, the extent to which these interventions are effective for children and adolescents of African descent is not well established. The increasing type 2 diabetes incidence and prevalence in children and adolescents of African descent in some OECD member countries underscores the need to pool available evidence to ascertain the effectiveness of lifestyle interventions for type 2 diabetes prevention in this population. INCLUSION CRITERIA: Lifestyle interventions to be considered include individual-or group-based lifestyle or behavioral modification interventions aimed at preventing or delaying the onset of type 2 diabetes in children and adolescents of African descent aged 19 years and under in OECD countries. Randomized controlled trials and non-randomized studies that assess the effectiveness of lifestyle interventions for type 2 diabetes prevention will be considered. METHODS: The databases to be searched include MEDLINE, Embase, CINAHL, PsycINFO, Social Services Abstracts, Cochrane Central Register of Controlled Trials, and ProQuest Dissertations and Theses Global databases. There will be no language or date limits placed on the search. Two independent reviewers will conduct the title, abstract, and full-text screening, followed by critical appraisal and data extraction. Data will undergo meta-analysis where appropriate, and will otherwise be presented as narrative synthesis. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021247267.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
