Brief summary
Obesity is common in Aboriginal and Torres Strait Islander communities and increases the risk of type 2 diabetes and heart disease. This WA-based study, designed in partnership with Aboriginal health and community groups, will test whether a medication called semaglutide (already shown to reduce weight and improve blood sugar and heart risk in other groups) can help improve health outcomes in Aboriginal people. The study will involve 200 Aboriginal or Torres Strait Islander participants, who will be supported with healthy eating, exercise, and regular check-ins. Some will receive weekly semaglutide injections, while others will receive a placebo. The study will measure changes in weight, blood pressure, blood sugar, and heart health over two years. This is the first trial of its kind in Aboriginal Australians and aims to guide future care.
Interventions
Semaglutide 0.25 mg subcutaneous injection weekly administered by healthcare professional and uptitrating every 4 weeks to 0.5 mg weekly, 1 mg weekly, 1.7 mg weekly and to a maximum of 2.4 mg weekly as tolerated; total duration of treatment will be 52 weeks. This will be in addition to background lifestyle support. Initial dietary education will occur as a 1 hour group session (up to 10 participants) led by a dietitician, which will be followed by sessions every three months at community centres led by a trained Aboriginal Health Worker. 1 hour exercise classes will be running weekly at the community centre supervised by. an exercise physiologist or physiotherapist so that participants are provided with a personalised exercise plan. These exercise classes may include a combination of aerobic and anaerobic exercises. Weekly check in duration of 15 minutes will occur one-on-one face-to-face with an Aboriginal Health Worker at the community centre, who will check on any side-effects, general well-being, and administer the injection.
