“…47 Second, we assessed studies according to the duration of follow-up (less than six months versus six months or longer), since it is known that early weight loss benefits are often not sustained over time. 48,49 Third, we also grouped studies by publication date, considering those published prior to 1995 as one group and those published in 1995 or after as another.…”

BACKGROUND:The use of computers to deliver education and support strategies has been shown to be effective in a variety of conditions. We conducted a systematic review and meta-analysis to evaluate the impact of computer-based technology on interventions for reducing weight. METHODS: We searched MEDLINE, CENTRAL, CINAHL, PsycINFO, Google Scholar and ClinicalTrials.gov (all updated through June 2010) for randomized controlled trials evaluating the effect of computer-based technology on education or support interventions aimed at reducing weight in overweight or obese adults. We calculated weighted mean differences (WMD) and 95% confidence intervals (CI) using random effects models. RESULTS: Eleven trials with 13 comparisons met inclusion criteria. Based on six comparisons, subjects who received a computer-based intervention as an addition to the standard intervention given to both groups lost significantly more weight (WMD −1.48 kg, 95% CI −2.52, -0.43). Conversely, based on six comparisons, subjects for whom computer-based technology was substituted to deliver an identical or highly comparable intervention to that of the control group lost significantly less weight (WMD 1.47 kg, 95% CI 0.13, 2.81). Significantly different weight loss seen in "addition" comparisons with less than six months of follow-up (WMD −1.95 kg, 95% CI −3.50, -0.40, two comparisons) was not seen in comparisons with longer follow-up (−1.08 kg, 95% CI −2.50, 0.34, four comparisons). Analyses based on quality and publication date did not substantially differ. CONCLUSIONS: While the addition of computer-based technology to weight loss interventions led to statistically greater weight loss, the magnitude (<1.5 kg) was small and unsustained.

A systematic review of interventions to improve health professionals’ management of obesity

et al. 1999

OBJECTIVE: To determine the existence and effectiveness of interventions to improve health professionals' management of obesity or the organisation of care for overweight and obese people. DESIGN: A systematic review of intervention studies, undertaken according to standard methods developed by the Cochrane Effective Practice and Organisation of Care (EPOC) Group. 1 PARTICIPANTS: Trained health care professionals and overweight and obese patients. MEASUREMENTS: Objective measures of health professionals' practice and behaviours, and patient outcomes including satisfaction, behaviour, psychological factors, disease status, risk factors, and measures of body weight, fat, or BMI. RESULTS: Twelve studies that met all the review inclusion criteria were identi®ed. Three were randomised controlled trials of health professional-oriented interventions (such as the use of reminders and training) and one was a controlled before and after study to improve collaboration between a hospital clinic and GPs. A further eight randomised controlled trials were identi®ed of interventions comparing either the deliverer of weight loss interventions or the setting of the delivery of the intervention. The heterogeneity and generally limited quality of identi®ed studies make it dif®cult to provide recommendations for improving health professionals' obesity management. CONCLUSIONS: At present, decisions about improving the provision of services for overweight and obese people must be based on the evidence from patient interventions and good clinical judgement. Future research is required to identify cost-effective strategies for improving health professionals' management and the organisation of care for overweight and obese people.A full version of this review, including detailed descriptions of the included studies and data tables, is available in the Cochrane Library.2 The Cochrane Library is a database of systematic review and other evidence on the effects of health care, available on CD ROM from Update Software.

Maintenance programmes after weight reduction — how useful are they?

Maintenance programmes lasting one or two years or even longer are generally recommended to improve long-term outcome after weight reduction. They may not be practical for several reasons: it is not known whether they really improve long term outcome or only delay relapse; they may lessen patients' motivation to take full responsibility for their life-style changes; and they need extra resources. Some series on treatment of obesity and experience with successful maintainers suggest that satisfactory long-term outcome can also be achieved without long maintenance programmes. We believe that weight reduction programmes lasting 4 ± 6 months can be developed to ensure better maintenance. The programmes should adopt a patient centred approach, support patients' full responsibility for lifestyle changes, and use principles and methods acceptable for most obese people.
