COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention includes attending the 'Beyond the Bump' community walk and talk program at the local park in which participants (n=25 per group; 100 total) will be offered postnatal care advice from experts in their fields for 15-20 min before engaging in a 30-minute walk in the community (borg scale 9-13/20) once a week for 10 weeks. Topics given will include dietetics, women's health physiotherapy, exercise physiology, psychology, child CPR, and neonatal development given by dietitians, women's health physiotherapists, exercise physiologists, psychologists, neonatology nurses, and neonatal developmental specialists.
Attendance will be taken at the beginning of each session to assess adherence.
Non-randomised trial. Participants that attend the intervention will be eligible to join the 'intervention' group. Participants that do not attend the intervention are eligible to join the control group.

Summary
Brief summary
To conduct a proof-of-concept trial to determine whether an ‘after delivery’ community care (education & physical activity) program impacts physical activity levels, diet quality, health behaviour and attitudes, and reduces risk factors for and incidence of Type 2 Diabetes in the 10 years post-delivery in mothers with a history of or risk factors for GDM, compared to control no=intervention.
