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 .
First versus repeat treatment with a lifestyle intervention program: attendance and weight loss outcomes
Objective : Following unblinding of the Diabetes Prevention Program ( DPP ) results , a 16-session lifestyle intervention program was offered to all study participants , including those who had initially been r and omized to lifestyle treatment . This study compares the effects of the lifestyle program between participants who had previous exposure and those who had not . Design : A 16-session behavioral intervention was conducted in groups at each of the 27 DPP sites during a transitional ( bridge ) period from the DPP trial to the DPP Outcomes Study ( DPPOS ) . Session participation for this 6-month behavioral weight loss program was confirmed by originally r and omized treatment groups . Subjects and measurements : Independently assessed weight measurements were available within a 7-month period before and after the program for 2808 ethnically diverse participants . Results : Participants from the lifestyle group in the DPP were the least likely to attend a repeat offering of a 16-session behavioral weight loss program conducted in groups . Weight loss during the transitional lifestyle program was strongly related to the duration of attendance in the three groups that were participating in the program for the first time ( metformin , placebo and troglitazone ) , but not related to amount of earlier weight loss . Conclusion : Individuals who were naive to the behavioral program  lost a greater amount of weight and this was strongly related to their degree of participation . A second exposure to a behavioral weight loss program result ed in unsatisfactory low attendance rates and weight loss
