A significant positive effect of the interventions on weight was reported by all study types .
The meta- analysis showed that lifestyle interventions achieved weight and waist circumference reductions after one year .
However , no clear effects on biochemical or clinical parameters were observed , possibly due to short follow-up periods or lack of power of the studies meta-analysed .
Changes in dietary parameters or physical activity were generally not reported .
Most studies assessing feasibility were supportive of implementation of lifestyle interventions in routine clinical care .
Conclusion Lifestyle interventions for patients at high risk of diabetes , delivered by a variety of healthcare providers in routine clinical setting s , are feasible but appear to be of limited clinical benefit one year after intervention .
Despite convincing evidence from structured intensive trials , this systematic review showed that translation into routine practice has less effect on diabetes risk reduction
Background The clinical effectiveness of intensive lifestyle interventions in preventing or delaying diabetes in people at high risk has been established from r and omised trials of structured , intensive interventions conducted in several countries over the past two decades .
The challenge is to translate them into routine clinical setting s. The objective of this review is to determine whether lifestyle interventions delivered to high-risk adult patients in routine clinical care setting s are feasible and effective in achieving reductions in risk factors for diabetes .
Randomized trial of lifestyle modification and pharmacotherapy for obesity.
BACKGROUND Weight-loss medications are recommended as an adjunct to a comprehensive program of diet , exercise , and behavior therapy but are typically prescribed with minimal or no lifestyle modification . This practice is likely to limit therapeutic benefits . METHODS In this one-year trial , we r and omly assigned 224 obese adults to receive 15 mg of sibutramine per day alone , delivered by a primary care provider in eight visits of 10 to 15 minutes each ; lifestyle-modification counseling alone , delivered in 30 group sessions ; sibutramine plus 30 group sessions of lifestyle-modification counseling ( i.e. , combined therapy ) ; or sibutramine plus brief lifestyle-modification counseling delivered by a primary care provider in eight visits of 10 to 15 minutes each . All subjects were prescribed a diet of 1200 to 1500 kcal per day and the same exercise regimen . RESULTS At one year , subjects who received combined therapy lost a mean ( + /-SD ) of 12.1+/-9.8 kg , whereas those receiving sibutramine alone lost 5.0+/-7.4 kg , those treated by lifestyle modification alone lost 6.7+/-7.9 kg , and those receiving sibutramine plus brief therapy lost 7.5+/-8.0 kg ( P<0.001 ) . Those in the combined-therapy group who frequently recorded their food intake lost more weight than those who did so infrequently ( 18.1+/-9.8 kg vs. 7.7+/-7.5 kg , P=0.04 ) . CONCLUSIONS The combination of medication and group lifestyle modification result ed in more weight loss than either medication or lifestyle modification alone . The results underscore the importance of prescribing weight-loss medications in combination with , rather than in lieu of , lifestyle modification
