Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be expected to attend two 60 minute group exercise classes per week for a 12 week period. The classes will be facilitated by qualified instructors. The classes will be in a circuit format, with minimal equipment, and are suitable for women of all fitness levels and can be modified to accommodate individual needs. Each participant will be given a pedometer to wear and will be asked to record their daily steps, and other physcial activity in their exercise log. During the 12 week program participants will also be required to attend 4 nutrition and lifestyle workshops facilitated by a qualified nutritionist.

Comparator / control treatment
No exercise, no nutrition workshops for 15 months. Then the comparator group undergoes the 12 week exercise and nutrition program.
Control group
Active

Outcomes
Primary outcome [1] 257988 0
Reduction in waist circumference.

Participants will have their height, weight, waist and hip circumference, and Body Mass Index (BMI) measured.
Timepoint [1] 257988 0
Baseline, 12 weeks, 24 weeks and 64 weeks.
Primary outcome [2] 257989 0
Improved average metabolic profile (lower blood pressure (BP)), improved cholesterol fraction, lower fasting glycemia, reduction in markers of inflammation).

Participants will have fasting blood collected for analysis, and their blood pressure taken.
Timepoint [2] 257989 0
Baseline, 12 weeks, 24 weeks and 64 weeks.
Primary outcome [3] 257990 0
Improved scores in tests of self-efficacy and social support for physical activity and self-reported diet, physical activity and sedentary behaviour, motives for physical activity and quality of life.
These measures will be assessed via self-reported questionnaires.
Timepoint [3] 257990 0
Baseline, 12 weeks, 24 weeks and 64 weeks.
Secondary outcome [1] 263544 0
Participant satisfaction interview with a semi-structured format.
Timepoint [1] 263544 0
12 weeks
Secondary outcome [2] 263545 0
Waist circumference interviews; 2 types, 1. Those maintaining waist loss from 12 weeks and 2. Those not maintaining waist loss from 12 weeks.

These interviews seek to understand the reasons behind participants' level of success in maintaining waist loss.
Timepoint [2] 263545 0
24 weeks and 64 weeks

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Advertising through local networks encourage possible participants to register their interest with researchers. Information sessions are also held. Potential participants are invited to attend baseline assessments. If eligible they will be randomly assigned to the active group or the comparator group. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e., computerised sequence generation)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
The coomparator group will receive the same intervention as the participants, but will be delayed by 64 weeks. The comparator group will also act as their own controls.

Summary
Brief summary
The aims of this intervention are:
1. To conduct environmental audits of obesogenic factors in the community and monitor any changes that might occur over the period of the study.
2. To demonstrate that central obesity (as measured by waist circumference) and associated diabetes risk among Indigenous women can be reduced and this reduction can be maintained with a locally planned and managed group-based physical fitness intervention.
3. To understand how individual and micro/macro environmental factors contribute to waist circumference trajectories from post-program to 3 and 12-months post-program.
