Physical activity interventions to prevent and manage type 2 diabetes among Aboriginal and Torres Strait Islander peoples: a systematic review protocol

Objective: This systematic review aims to synthesize evidence to determine the effect of physical activity on the prevention and management of type 2 diabetes among Aboriginal and Torres Strait Islander Australians. Introduction: Physical activity interventions have been shown to have a positive influence in the prevention and management of type 2 diabetes. A body of evidence for the impact among Aboriginal and Torres Strait Islander people is emerging, but a definitive understanding is yet to be realized. Inclusion criteria: The review will include studies with Aboriginal and Torres Strait Islander populations of any age group and from any setting or region in Australia. Studies will be included if they report on physical activity interventions, programs, or activities to prevent or manage type 2 diabetes. Studies may compare physical activity interventions to usual care, alternate treatments, or no intervention, or may be pre-post studies. This review will consider studies that measure change in physical activity or exercise levels and/or change in HbA1c level. Methods: Nine databases will be searched, and studies published in English will be included. No date limits will be set. Methodological quality will be determined using critical appraisal checklists appropriate to the study design and the CREATE Critical Appraisal Tool to appraise research from Aboriginal and Torres Strait Islander perspectives. Data extracted will include population group, study design, methods, intervention components, and physical activityrelated outcomes. Quantitative data will be pooled where possible to enable a meta-analysis to be conducted. Heterogeneous studies will be synthesized narratively.
