Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The internet based program will run for 12 weeks. Participants work through a new session each week for a self directed period of time (between 30-60mins recommended). Activities and goals will be set for each week. Goals will be set by the participant from a framework recommended within the program (for example to increase moderate activity from 0 to 30 mins on most days) and reviewed every week, activities will be specific to intervention group but not to each individual. Participants will be recommended to gradually increase their physical activity until they are reaching a minimum of 60 minutes moderate to vigorous activity per day. All participants in the intervention group will receive a pedometer and a walking program to help achieve this goal. Cognitive behaviour aspect of the program will address self monitoring, goal setting, stimulus control, social eating etc. Diet and exercise info will be recorded in weekly online diaries the participant completes. Participants will receive feedback at least weekly. Parents of participants will be sent monthly newsletters for the 3 months of the intervention program with tips on creating a supportive environment. After the 12 week program is finished participants will receive monthly follow up via text or email (whichever preferred) asking them to review their eating and physical activity habits, and provide feedback. They can also review the materials from the program. Breakdown of weekly session themes/content (activities and goals will be based around this): Session One: Introduces key themes and concepts (lifestyle change, red foods/ green foods, good/ not so good reasons to change your lifestyle habits, understanding portion sizes). Session Two: Info on physical activity and why it is important, and difference between moderate and vigorous activity. Session Three: Setting goals and an exercise plan. Session Four: Understanding nutrition labels, how to eat out healthily. Session Five: Binge Eating- what it is, recognise it and how to reduce it. Paying attention to body cues. Mindful eating, a way to relax and eat in a healthy way. Session Six: Body image and self esteem, Triggers: Direct and indirect. Session Seven: Barriers to eating healthy, and how to overcome them Ways to get active, Creating healthy sleep routines. Session Eight: How to keep snacks healthy, the truth about diets and diet pills. Session Nine: What are eating disorders? Body image triggers and tips for avoiding a negative body image, challenging negative thoughts. Session Ten: Creating a good food environment, coping with cravings. Session Eleven: How to not take part in perpetuating stigma about weight, Ways to stay confident, Strategies for helping people deal with teasing. Session Twelve : Long term goal setting, weight maintenance. Tips for staying on top of eating and exercise. What to take away from Staying Fit.

Lifestyle
Comparator / control treatment
The control treatment will receive publicly available generic health information about healthy eating and physical activity at the beginning of the 12 week treatment period. This information will be sourced from reliable health information websites (government/ evidence based) and presented in both paper and online format (e.g. participant will receive a pack with flyers about the physical activity requirements for adolescents, general information about healthy eating and planning healthy meals and a sheet with links to websites about the healthy eating, physical activity and mental health- all websites will be age appropriate). There will be no Cognitive behaviour aspect for the control group. It is up to the control participants whether they read the paper information given and/or access the available websites. This group will self direct their use of the control information.
The control group will receive a hard copy of the program sessions once the program and follow up are completed. Again, the length of time spent on these sessions will be self directed.

Adherence will be monitored by the participants completion of program (submitting weekly logs), and satisfaction with program content will be measured by simple questions at the end of most of the 12 sessions (e.g. how interesting was this session? scaled from 'not interesting' to 'very interesting'). Also at 3, 6 and 12 month follow up participants will be asked about their satisfaction with the program overall (these questions still under development).

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)
At the initial meeting (if formal consent has been fully given) baseline measurement will be completed and participant will be randomised to either the treatment or control arm of the study. The research team member will contact the statistician (by phone) who holds the allocation schedule to ascertain whether or not the participant is in the intervention or control group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Prior to recruitment, a randomisation list will be computer generated using random permuted blocks with varying block sizes (4, 6 and 8 randomly arranged) with a ratio of 1:1 assignment by the trial statistician (Dr Romaniuk) and checked by a reviewing statistician from the Clinical Epidemiology and Biostatistics Unit. Block sizes will not be documented in the protocol to protect allocation concealment and the randomisation list will be stored in a location that is not accessible to the research personnel. After recruitment into the study, web-based randomisation will be used to determine if the participant will be in the intervention or control group according to the next consecutive random allocation on the list.

Summary
Brief summary
Staying Fit has been designed as an Internet-based adolescent weight management program for overweight or mildly obese Australian young people.

Goals of the program include: targeting weight loss, promoting weight maintenance, decreasing weight and shape concerns, healthy eating and increasing physical activity.

We propose to conduct a project, commencing in July, 2011, in metropolitan Melbourne, involving approximately 570 young people aged 12-17 years. We will be recruiting voluntary participants from the community via advertisements in local media, posters in youth friendly services and through school nurses and general practitioners.
Parent consent will be sought using an active consent process; young people will not be able to participate without a signed consent form from their parent or guardian. Participation for the young person is completely voluntary and they will also be required to provide written consent.
Half of the participants will be randomly assigned to the intervention group, and will participate in the program with access to all modules. The other participants will be randomly assigned to the control group, and will receive a list of health websites and handouts on healthy food choices and physical activity recommendations.
There are 12 sessions in the program and it takes approximately 1-2 hours to work through each session. Sessions are released at the rate of one each week. Online interactive monitoring of key behaviours (e.g., food and physical activity logs) and an online discussion group are used to encourage participation.
Data will be collected at the start of the program, at 3 months, 6 months and 12 months. Data from the project will be collected and analysed by the Centre for Adolescent Health (CAH) at the Royal Children’s Hospital.
