Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Active Breed is a 12-week men's health intervention targeting:
- weight loss through sustainable healthy lifestyle behaviours
- physical activity, including goal setting, strategies to increase physical activity and overcoming barriers
- nutrition, including increasing fruit and vegetable consumption, reducing saturated fat, salt, sugar and processed food intake
- mental health, including depression and anxiety and practical strategies to deal with stress
- violence prevention, including recognising signs of abuse and violence
The intervention will be tested as a two-armed randomised controlled trial, with a wait-list control group who will receive the intervention at a later date.

Group-based (face-to-face) sessions will be held once per week for 12 weeks at Belmore Sports Ground (Bulldogs' home stadium). Each weekly session will run for 90 minutes and will comprise an educational component (45-60 minutes) and a physical activity component (30-45 minutes). These sessions will be delivered by trained Active Breed facilitators, with support from content area experts including qualified exercise scientists and personal trainers (physical activity), mental health support services (representative from Beyond Blue for mental health), and domestic violence experts (representatives from White Ribbon Australia). Active Breed facilitators will have expertise in physical activity and exercise (e.g., qualified exercise scientists) and will attend a half day training course with two senior members of the research team (PhD qualified) with expertise in health promotion, physical education and men's health. During this session, facilitators will learn about engaging men, delivering gender-tailored information, building rapport with participants, and the content within the program. Senior members of the research team will be in attendance at all sessions, and facilitators will be involved in a debriefing session with the researcher/s after each session to identify strengths and areas for improvement.

One topic will be covered in each educational session, and these topics will be scheduled prior. The content delivery will vary in each session, and activities will include brief, interactive presentations and demonstrations (e.g., cooking class) and group discussion activities.

The weekly physical activity component of the sessions will include low to moderate intensity football skills and drills, small-sided touch football games, and supervised gym sessions. All physical activity sessions will be delivered by a qualified personal trainer and/or exercise scientist.

All participants will be provided with program resources including an Active Breed handbook (specifically developed for the program), generic information about health and health services (readily available, to be provided by external facilitators from external stakeholders), equipment pack (including a training shirt and drink bottle), and exclusive access to a participant website where program materials will be made available outside regular weekly sessions.

Participants will be encouraged to engage with the website at least weekly to support healthy lifestyle behaviours beyond the scope of the weekly sessions. Each intervention participant will receive a unique login allowing exclusive access to the website. We will explore the usability and engagement with the website in the process evaluation of the pilot study.

Adherence to the intervention will be monitored by attendance records at the weekly sessions. Interactions with the website will also be recorded (e.g., number of logins).

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be required to complete a pre-exercise screening assessment prior to participating in the study. Once cleared, participants will be randomly allocated to the intervention or wait-list control group.

The random allocation sequence will be generated by a statistician. Study information for the intervention and wait-list control groups will be placed into opaque envelopes and consecutively numbered according to the randomisation schedule. This process will be completed by a research assistant who is not involved in enrolment, assessment or allocation of participants.

Upon completion of baseline measurements, participants will meet with a research assistant (not involved in measurement) in a separate room to open the allocation envelope. The research assistant will explain the allocation based on the information contained in the envelope.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation allocation sequence will be generated by a statistician who will not have any contact with participants during the trial. The statistician will generate a randomisation table created by computer software (i.e. computerised sequence generation). The randomisation allocation sequence will be stored securely and concealed from research assistants involved in data collection, group allocation and data entry.

Statistical methods / analysis
This pilot study will test the efficacy of the intervention and will provide baseline data for a power analysis for a larger-scale intervention.

Generalised linear mixed models will examine differences in primary and secondary outcomes between treatment groups. Qualitative data from the process evaluation will be analysed using hierarchical content analysis to generate meaning units, categories and themes.

Summary
Brief summary
Australian men are recognised as hard-to-reach for the promotion of healthy lifestyles and disease prevention. Evidence suggests, however, that when gender-specific concerns and approaches frame program design and delivery, men tend to engage with weight management, physical activity (PA) and health promotion initiatives. Active Breed is a 12-week, gender-tailored men's health program targeting weight loss, physical activity, nutrition, mental health, and violence prevention. The program will be delivered through the Canterbury-Bankstown Bulldogs Rugby League club and will include weekly education and physical activity sessions held at the club's home stadium.
