Intervention-only programmes were in general more cost effective than programmes that also included a screening component .
The longer the period evaluated , the more cost-effective interventions appeared .
There was insufficient evidence to answer the question of ( 1 ) whether lifestyle programmes are more cost effective than metformin or ( 2 ) whether low-intensity lifestyle interventions are more cost effective than the more intensive lifestyle programmes that were tested in trials .

Effects of lifestyle intervention and meal replacement on glycaemic and body-weight control in Chinese subjects with impaired glucose regulation: a 1-year randomised controlled trial.
The purpose of the present study was to evaluate the impact of a lifestyle intervention programme , combined with a daily low-glycaemic index meal replacement , on body-weight and glycaemic control in subjects with impaired glucose regulation ( IGR ) . Subjects with IGR were r and omly assigned to an intervention group ( n 46 ) and a control group ( n 42 ) . Both groups received health counselling at baseline . The intervention group also received a daily meal replacement and intensive lifestyle intervention to promote healthy eating habits during the first 3 months of the study , and follow-up visits performed monthly until the end of the 1-year study . Outcome measurements included changes in plasma glucose , glycated Hb ( HbA1c ) , plasma lipids , body weight , blood pressure and body composition ( such as body fat mass and visceral fat area ) . The results showed that body-weight loss after 1 year was significant in the intervention group compared with the control group ( -1·8 ( SEM 0·35 ) v. -0·6 ( SEM 0·40 ) 2·5 kg , P<0·05 ) . The 2 h plasma glucose concentration decreased 1·24 mmol/l in the intervention group and increased 0·85 mmol/l in the control group ( P<0·05 ) compared with their baseline , respectively . A 5 kg body-weight loss at 1 year was associated with a decrease of 1·49 mmol/l in 2 h plasma glucose ( P<0·01 ) . The incidence of normal glucose regulation ( NGR ) in the two groups was significantly different ( P=0·001 ) . In conclusion , the combination of regular contact , lifestyle advice and meal replacement is beneficial in promoting IGR to NGR
