Do Text Message Reminders Increase Preoperative Exercise in Obesity Surgery Candidates?

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.

Treatment and study plan

Daily text message reminders

Behavioral

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

Primary outcomes

  1. Proportion of patients partaking in the minimum recommended amount of weekly physical activity

    Time frame: 6 weeks post recruitment

    >450 METmins per week of physical activity as measured by the internationally and locally validated IPAQ questionnaire.

Secondary outcomes

  1. Postoperative Physical Activity

    Time frame: 6 weeks postoperatively

    Quantity of physical acitivty will be measured as METmins per week as measured by the IPAQ questionnaire

  2. Functional capacity

    Time frame: Baseline and 6 weeks post recuitment (preoperatively)

    Measured using the 6 minute walk test

  3. Length of Hospital Stay

    Time frame: As assessed at day of discharge

    Total number of days spent in hospital following their operation

  4. Short term weight loss

    Time frame: Out to 6 months postoperatively

    Postoperative weight loss as measured by percentage of excess weight loss

  5. Perioperative complications

    Time frame: Out to 30 days postoperatively

    Prospectively recorded postoperative complications graded according the Clavien-Dindo classification system
