Can healthy volunteers participate?
No
Key exclusion criteria
Pre-menopausal women. Women diagnosed with breast cancer still undergoing primary treatment. Those engaging in less than six hours of sitting each day; more than 75 minutes of moderate-vigorous physical activity per week.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Initial telephone screening is conducted by the Study Coordinator. Eligible participants are sent a baseline sociodemographic questionnaire, accelerometer/inclinometer and consent form. If these baseline data collection measures are completed and returned, along with the consent form, to the study team, participants are then randomised by another team member who will have no personal contact with participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using the ‘ralloc’ Stata module.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment

Other design features
A two-arm design of which part 1 is a traditional randomised control trial; part 2 combines a maintenance phase for the intervention participants of part 1 plus an abridged intervention phase for the control participants of part 1.

Efficacy
Statistical methods / analysis
Baseline characteristics will be summarised across the treatment groups. Should unexpected imbalances between the two groups occur by chance, they will be corrected in an adjusted analysis. To determine the effect of the intervention on both physical activity and sitting time, the trial analysis will be performed following the intention-to-treat principle. The analysis will therefore include all participants who were randomized (n=92) regardless of their compliance levels. Intervention effects will be assessed using linear mixed models for continuous variables. This model includes random effects associated with the units of analysis (participants), and allows the residuals associated with the longitudinal measures on the same unit of analysis to be correlated. This approach includes all available data at each time point, and may be adjusted for covariates if imbalances between groups are noted.
Linear mixed models will also be used to address the secondary aims of the study. Here, we will only consider the within-group change (aims 2 and 3 do not have a control condition). All analyses will be conducted using Stata statistical software version 12 (Statacorp, College Station, TX, USA).
Our sample size calculation is based on Aim 1: determining the efficacy of the primary intervention (use of wearable technology, coupled with brief behavioural counselling and goal setting) in increasing physical activity and reducing sitting time. The sample size for this study enables detection of a difference in physical activity between primary intervention and wait-list control groups at T2 of 75 minutes per week. Assuming a standard deviation of change of 120 minutes and allowing 10% attrition, 46 women per group (92 participants in total; 82 at end of intervention) will be needed to detect this minimum difference in total physical activity between groups with 80% power and a type I error of 5% (two-tailed). With a final sample size of 82 we will have 99% power to detect a difference of 75 minutes per day of sitting time between groups, assuming a standard deviation of change of 107 minutes.
