Description of intervention(s) / exposure
1. Medium personalisation group - will receive access to a website tailored to women with a history of gestational diabetes and personalised text messages over a 3 month period.
The materials on the 'Body Balance Beyond' gestational diabetes (BBBGDM) website are predominantly self-directed and designed to promote modest weight loss through supporting participants to make a series of small changes to eating and exercise behaviours and form new healthy habits. Participants will have access to the site for 3 months and can accessed at their discretion. Website usage metrics will be captured using Google Analytics.
The BBBGDM website contains five sections:
a) Managing my risk - outlines the risk factors for developing diabetes in the future and actions which can reduce risk.
b) My Plan - participants will be emailed personalised feedback reports on dietary intake and physical activity (generated from the Australian Eating Survey and Godin activity questionnaires) in comparison to national nutrition and exercise guidelines. This section guides participants through using their reports to set weight-, diet- and exercise-related goals, and strategies for self-monitoring and managing relapses.
c) Eating - contains information and links to resources to promote healthy eating (e.g. portion size, energy density, meal planning, label reading, recipes, breastfeeding).
d) Physical Activity - contains information and links to resources to promote being more active (e.g. types of activity, benefits, suggestions for being active with a family, exercising safely).
e) Wellbeing - contains information and resources on social support, stress management and sleep.
In addition, participants in this group will receive three text messages per week. The messages will consist of reminders to self-monitor or reflect on goals and two personalised messages (one diet-related and one exercise-related) addressing the participant’s self-identified barriers to healthy eating and being more physically active. An example of a personalised text message addressing the factor of improving meal planning skills is "[First Name]: Looking to improve your menu planning skills? Click here [Link] for tips on creating a healthy menu, and other great advice."

2. High personalisation group - access to the BBBGDM website and personalised text messages (as described above for the medium personalisation group). In addition, this group will receive five video coaching sessions (20-30 mins duration each) with a dietitian (Weeks 2 and 5) and exercise physiologist (Weeks 3 and 6), with the participant asked to select which practitioner they wish to see for the final session (Week 9) . The video coaching comprises structured participant-centred coaching sessions to refine participant goals. During these sessions the dietitian and exercise physiologist will personalise strategies to overcome participant's self-identified factors affecting diet and exercise, in addition to review progress and revise goals, and problem solve barriers and revise strategies. Participant attendance will be recorded via checklist.
