A text message based weight management intervention for overweight adults

BackgroundWeight management interventions can be extended using mobile telephone technology to deliver support in real-time, real-world settings. The present study aimed to determine whether text messaging helped patients maintain or lose weight following a weight-loss programme. MethodsIn this controlled study, overweight and obese [body mass index (BMI) >30kgm(-2) or >28kgm(-2) with co-morbidities] adults who completed a weight-loss programme participated in an additional 12-week text message intervention [Lifestyle, Eating and Activity Programme (LEAP) Beep]. Patients were allocated goals for steps, fruit, vegetable and breakfast consumption. Patients regularly texted' their progress and received tailored practitioner feedback. Pre/post-intervention body weight, waist circumference (WC), BMI, quality of life (QOL), anxiety and depression measurements were compared retrospectively with a control group offered weight checks only. ResultsCompared to control (n=17), the intervention group's (n=17) body weight, WC and BMI reduced significantly (-1.6 versus 0.7kg, P=0.006; -2.2 versus 1.5cm, P=0.0005; -0.6 versus 0.7kgm(-2), P=0.03, respectively). QOL and depression scores also improved (-6.8 versus 1 point, P=0.134; -0.2 versus 0.2 points, P=0.228). No difference was observed in anxiety scores between the groups. Intervention versus control group follow-up attendance improved significantly (4.4 versus 1.7 attendances, P=0.0005). ConclusionsLEAP Beep promoted losses in weight, WC and BMI, and improved QOL parameters and follow-up attendance. Text messaging is a cheap, portable, convenient and innovative medium facilitating goal setting, self-monitoring and information exchange. Further improvements to automation at the same time as maintaining individual support are necessary to ease practitioner burden. Text messaging offers cost-efficient dietetic input, opening up possibilities for practitioner-to-patient support and yields positive weight outcomes following initial weight loss.
