Obesity Interventions for Aboriginal and Torres Strait Islander Children and Adolescents: A Scoping Review of Impact and Outcomes

Background : Childhood Obesity is a significant and growing Public Health threat among Aboriginal and Torres Strait Islander (ATSI) children and adolescents in Australia. Health sectors in Australia have been focusing on health intervention programs across various states to prevent childhood obesity. This review aims to analyse the impact of obesity intervention programs conducted among children and adolescents of ATSI communities across Australia and report on the best practices for conducting future research. Objectives: This scoping review synthesised existing literature on the obesity prevention interventions programs among ATSI Children and Adolescents in Australia and examined their scope, implementation, and outcomes; evaluated their cultural appropriateness; and highlighted critical enablers and barriers. Methods : This scoping review analysed scholarly journal articles that reported on the findings of obesity intervention programs delivered across ATSI children and adolescents. Only Quasi-experimental and Randomized Control Trials (RCTs) were selected for the review. A full search has been carried out in Health databases such as Cochrane Library, Medline, PubMed, and ProQuest Central for the past 15 years. The framework of the Joanna Briggs Institute (JBI) for Scoping reviews was followed throughout this review. Results : Eleven studies met inclusion criteria. Findings were clustered into five themes: (i) community-led, systems-based interventions improved health behaviours and anthropometry; (ii) culturally tailored, community-embedded programs enhanced engagement and health literacy; (iii) early childhood and family-focused approaches showed promise; (iv) community or policy initiatives yielded mixed results; and (v) behavioural interventions were ineffective without addressing social and structural determinants. The most effective programs were community-delivered, multi-stakeholder, and centred on empowerment and capacity building. Conclusions : Obesity prevention efforts targeting Aboriginal and Torres Strait Islander children and adolescents are most successful when community-led, culturally grounded, and supported by multiple stakeholders. These findings underscore the necessity of culturally sensitive, participatory approaches. Further research is needed to strengthen the evidence base and inform sustainable, policy-relevant strategies for childhood obesity.
