Description of intervention(s) / exposure
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.
