A Randomised Trial of Text Message Support for Reducing Weight Regain Following Sleeve Gastrectomy
Sleeve gastrectomy (SG) is a common bariatric procedure with high rates of weight regain (WR). Clinicians and patients have identified a lack of follow-up support and maladaptive lifestyle behaviours as potential causes for WR. While text message support has been shown to be effective for weight loss in non-surgical patients, it has not been investigated for reducing WR in bariatric patients.
To determine the effectiveness of text message support in reducing weight regain following sleeve gastrectomy.
A text message intervention was designed. The effectiveness of the intervention was investigated by a randomised trial powered to detect a 15% difference in the primary outcome of percent excess weight loss (84 participants required). Secondary outcomes were the Bariatric Analysis and Reporting System (BAROS) score and patient satisfaction. Outcomes were assessed at 6 and 12 months.
Ninety-five participants were randomised to either standard care or text message support (daily text message for 1 year). While there was no significant difference in the primary outcome at 6 or 12 months, patients who received the intervention tended to have less WR and a significantly better BAROS score at 12 months. Participants who received text message support found it beneficial, would have liked the messages to continue, and felt WR was reduced by having the text message support.
Text message support following SG is feasible, may reduce weight regain, improves the BAROS score and is valued by patients.
