  Purpose

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.

Primary Outcome Measures:
  • Proportion of patients partaking in the minimum recommended amount of weekly physical activity [ Time Frame: 6 weeks post recruitment ] [ Designated as safety issue: No ]
    >450 METmins per week of physical activity as measured by the internationally and locally validated IPAQ questionnaire.


Secondary Outcome Measures:
  • Postoperative Physical Activity [ Time Frame: 6 weeks postoperatively ] [ Designated as safety issue: No ]
    Quantity of physical acitivty will be measured as METmins per week as measured by the IPAQ questionnaire

  • Functional capacity [ Time Frame: Baseline and 6 weeks post recuitment (preoperatively) ] [ Designated as safety issue: No ]
    Measured using the 6 minute walk test

  • Length of Hospital Stay [ Time Frame: As assessed at day of discharge ] [ Designated as safety issue: No ]
    Total number of days spent in hospital following their operation

  • Short term weight loss [ Time Frame: Out to 6 months postoperatively ] [ Designated as safety issue: No ]
    Postoperative weight loss as measured by percentage of excess weight loss

  • Perioperative complications [ Time Frame: Out to 30 days postoperatively ] [ Designated as safety issue: Yes ]
    Prospectively recorded postoperative complications graded according the Clavien-Dindo classification system

Arms Assigned Interventions
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.
Behavioral: Daily text message reminders
Daily text message reminders to motivate patients to exercise in conjunction with an exercise information sheet.
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.
