Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

BEHAVIORAL - Daily text message reminders

Experimental: Text message group - Patients randomised to this group will receive daily text message reminders used to motivate them to exercise in the preoperative period. They will also receive an exercise information sheet to complement the text messages.

No intervention: No text message group - Patients randomised to this group will receive standardised exercise advice but will not receive the text message reminders or the exercise information sheet.


BEHAVIORAL: Daily text message reminders
Daily text message reminders to motivate patients to exercise in conjunction with an exercise information sheet.

Summary
Brief summary
Preoperative exercise has been shown to improve physiological and functional capacity in patients undergoing abdominal surgery to prepare them for the stress of surgery. Patients undergoing bariatric surgery are advised to partake in regular preoperative exercise. In the setting of bariatric surgery, as well as preparing patients for the stress of surgery, it is also thought to increase the likelihood that they will exercise postoperatively. However, compliance to this advice is extremely low. Text-message interventions have been shown to improve compliance to other lifestyle interventions. The investigators will compare the rate of compliance to preoperative exercise prior to bariatric surgery in patients who receive a daily text message to those who do not. The investigators will also compare weight loss.
