Are computer-based interventions for weight loss effective?
From: The Cochrane Collaboration
- Wieland, L.S., Falzon, L., Sciamanna, C.N., Trudeau, K.J., Brodney Folse, S., Schwartz, J.E., Davidson, K.W., 2012. Interactive computer-based interventions for weight loss or weight maintenance in overweight or obese people, in: Cochrane Database of Systematic Reviews. John Wiley & Sons, Ltd.
- 18 trials with 4,140 participants
- The paper is a systematic review / meta analysis of all relevant trials.
- This means that the data from all similar trials has been grouped together to form an overall outcome.
- At 6 months, computer-based interventions led to greater weight loss than minimal interventions (average weight loss of 1.5kg), but less weight loss than in-person treatment (average 2.1 kg).
- At 6 months, computer-based interventions were superior to a minimal interventions in limiting weight regain, but was not as effective as infrequent in-person treatment.
- Compared to no intervention or minimal interventions (pamphlets, usual care), interactive computer-based programs are an effective intervention for weight loss and weight maintenance.
- Compared to in-person interventions, interactive computer-based programs result in smaller weight losses and lower levels of weight maintenance.
- Treatment duration was between four weeks and 30 months.
- Yes (without confidence); when compared to minimal interventions such as pamphlets.
