Improving management of obesity in primary care: cluster randomised trial

To evaluate a training programme intended to improve the management of obesity, delivered to general practice teams.

Cluster randomised trial.

Northern and Yorkshire region of England.

44 general practices invited consecutively attending obese adults to participate; 843 patients attended for collection of baseline data and were subsequently randomised.

4.5 hour training programme promoting an obesity management model.

Difference in weight between patients in intervention and control groups at 12 months (main outcome measure) and at 3 months and 18 months; change in practitioners' knowledge and behaviour in obesity management consultations.

Twelve months after training the patients in the intervention group were 1 (95% confidence interval--1.9 to 3.9) kg heavier than controls (P = 0.5). Some evidence indicated that practitioners' knowledge had improved. Some aspects of the management model, including recording weight, target weight, and dietary targets, occurred more frequently in intervention practices after the training, but in absolute terms levels of implementation were low.

A training package promoting a brief, prescriptive approach to the treatment of obesity through lifestyle modification, intended to be incorporated into routine clinical practice, did not ultimately affect the weight of this motivated and at risk cohort of patients.
