Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
After gaining informed consent, eligible participants will complete a baseline survey of their current physical activity level and wear an Actigraph accelerometer for 7 days, issued by the research assistant. Participants randomised to the intervention group will attend a one-hour workshop, held at the University of Sydney or Royal Prince Alfred Hospital.
The workshop will be delivered by one of the investigators (CS, AT, CC, LH or RS), who are also University academic staff members and registered Physiotherapists. Information will be given about the importance of physical activity for maximising physical and mental health and preventing disability in women and to provide information about existing opportunities to participate in and enhance physical activity participation. Video interviews will be shown at the workshop of 4 current and retired University female staff who are over 50 and manage to fit physical activity into their busy lives and experience the benefits. The COM-B behaviour change framework, which focuses on capability opportunity and motivation, will be used to guide the design of the intervention. Workshop materials will be made freely available at the completion of the workshop. Existing physical activity opportunities that will be referred to include the a) on-campus activities and facilities b) websites providing information and programmes, for example the Active and Healthy website, a freely-available database of physical activity opportunities for the over 50s run by the NSW Ministry of health, the Get Healthy coaching service run by the NSW Ministry of health and the Global Corporate Challenge supported by the University; c) suggestions of some free applications for smartphone devices that enhance physical activity (for example, "Couch 2 5K", "Map my run").
Participants who are unable to physically attend the workshops will be offered attendance via video-conferencing facilities or via an online recording of the workshop with the opportunity to ask any questions to the presenters by email or telephone.
An on-line discussion group will be set up for those who wish to remain in contact, and fortnightly emails supporting behaviour change will be sent to those who wish to receive these. Workshop participants will also be offered the use of a pedometer or internet-connected activity tracker (Fitbit) for the duration of the study (3 months), to provide motivation and feedback to increase activity levels. Participants will be re-evaluated by survey and Actigraph accelerometer 3 months after the workshop, and will be asked about their goals attained, and which additional activities and support approaches were undertaken.

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)
For eligible people who consent to participate in the study, a baseline assessment will be conducted. At the end of the assessment group allocation will be determined using concealed allocation. Concealed allocation will be achieved by the randomisation schedule being embedded in a secure online database (REDCap).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A variable block randomisation schedule will be prepared from a computer-generated list of random numbers by a researcher not involved in the recruitment of participants in the trial. The randomisation schedule will incorporate stratification for University campus.

Efficacy
Statistical methods / analysis
Data analysis will be blinded, by intention-to-treat and guided by a detailed statistical analysis plan. Analysis and interpretation (also performed blinded) on the primary and key secondary outcomes will be conducted by the research team. A p-value of < 0.05 will be considered statistically significant. A full Statistical Analysis Plan will be devised by the lead investigator prior to completion of recruitment.
Odds ratios will be calculated to assess the effect of group allocation on the dichotomously-scored primary outcome (proportion of people achieving 10,000 steps/ day) and secondary outcome (proportion of people achieving physical activity in accordance with national guidelines). General linear models will assess the effect of group allocation on the continuously-scored secondary outcomes (weekly hours of physical activity, function and mood), adjusting for baseline scores.
A total of 50 participants per group (i.e. 100 participants) will provide 80% power to detect 30% more people in the intervention group reaching the recommended 10,000 steps/ day than the control group. This calculation assumed a proportion of 27% compliance with the 10,000 steps/ day activity level in the control group, dropout rate of 15% and alpha of 5%. The estimates of mean proportion of people achieving 10,000 steps/ day activity level was taken from the baseline results of the University of Sydney staff participating in the Global Corporate Challenge, Analyses will be pre-planned, conducted while masked to group allocation and will use an intention-to-treat approach. Analyses will be conducted using the Stata 13 software package.

Summary
Brief summary
This randomised waiting list controlled trial aims to test the impact of an intervention designed to enhance ongoing physical activity participation in women aged over 50.
100 female University staff aged 50 years and older will be recruited via University newsletters and websites. Exclusion criteria are limited English skills, a medical condition precluding participation in regular exercise, or currently meeting physical activity guidelines.
Upon giving informed consent participants will complete a baseline survey on physical activity knowledge, attitudes and behaviour, physical functioning and mood. Current physical activity level will be measured with an accelerometer, worn on the hip for 7 consecutive days to determine the average daily step count.
Participants will then be randomised to attend a workshop immediately, or after 3 months. At 3 months post randomisation, similar surveys and wearing the accelerometer will be repeated.
The intervention will be a one-hour workshop to give information about the importance of physical activity for maximising physical and mental health and preventing disability in women, and to provide information about existing opportunities to participate in and enhance physical activity.
An email list and on-line discussion group will be set up for those wishing to remain in contact. Workshop materials will be made freely available at the completion of the project, and participants will also be offered the use of a pedometer or internet-connected activity tracker (Fitbit) for the duration of the study, to provide motivation and feedback to increase activity levels.
Participants randomised to the control group will be allocated to a waiting list and receive access to the intervention after the 3-month follow-up period.
The primary outcome will be the proportion of people achieving an average of at least 10,000 daily steps, measured with an accelerometer.
The secondary outcomes will be the proportion of people achieving adequate physical activity levels as recommended by national physical activity guidelines, average total number of hours of physical activity per week, change in perceived benefits of and barriers to exercise participation, physical functioning, mood.
Analyses will be pre-planned, conducted while masked to group allocation and will use an intention-to-treat approach.
50 participants per group (i.e. 100 participants) will provide 80% power to detect 30% more people in the intervention group reaching the recommended 10,000 steps/day than the control group. This calculation assumed a proportion of 27% compliance with the 10,000 steps/day activity level in the control group, 15% dropout rate and 5% alpha.
This sample size is also expected to be sufficient to detect between-group differences in the order of 10-15% for the secondary outcome measures.
If shown to be effective, this study is an approach that could be implemented more broadly to increase the population health impact.
