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 .
OBJECTIVE Explore the cost-effectiveness of lifestyle interventions and metformin in reducing subsequent incidence of type 2 diabetes  , both alone and in combination with a screening programme to identify high-risk individuals .
Effectiveness of a Pragmatic Education Program Designed to Promote Walking Activity in Individuals With Impaired Glucose Tolerance
OBJECTIVE To investigate whether a pragmatic structured education program with and without pedometer use is effective for promoting physical activity and improving glucose tolerance in those with impaired glucose tolerance ( IGT ) . RESEARCH DESIGN AND METHODS Overweight and obese individuals with IGT were recruited from ongoing screening studies at the University Hospitals of Leicester , U.K. Participants were r and omly assigned to one of three groups . Group 1 received a 3-h group-based structured education program design ed to promote walking activity using personalized steps-per-day goals and pedometers . Group 2 received a 3-h group-based structured education program design ed to promote walking activity using generic time-based goals . Group 3 received a brief information leaflet ( control condition ) . Outcomes included an oral glucose tolerance test , st and ard anthropometric measures , ambulatory activity , and psychological variables . Follow-up was conducted at 3 , 6 , and 12 months . RESULTS A total of 87 individuals ( 66 % male , mean age 65 years ) were included in this study . At 12 months , significant decreases in 2-h postchallenge glucose and fasting glucose of −1.31 mmol/l ( 95 % CI −2.20 to −0.43 ) and −0.32 mmol/l ( −0.59 to −0.03 ) , respectively , were seen in the pedometer group compared with the control group . No significant improvements in glucose control were seen in those given the st and ard education program . CONCLUSIONS This study suggests that a pragmatic structured education program that incorporates pedometer use is effective for improving glucose tolerance in those with IGT . This result is likely to have important implication s for future primary care – based diabetes prevention initiatives
