The Community Prevention Services Taskforce in the US commissioned an evidence review of the effectiveness of programmes to promote exercise and weight loss on prevention of diabetes. The headline message is that programmes targeting both weight loss and exercise are effective at reducing the onset of diabetes by about 40% over a three to six year period. Intensive programmes are more effective than less intensive ones. The diet/exercise programmes also resulted in improvement in blood fats and systolic blood pressure. The literature is extensive – 53 studies in all, and there was no evidence of publication bias on Egger’s test. We will discuss health economic analysis of the intervention in a forthcoming news blog.
