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 controlled trial of a new dietary education program to prevent type 2 diabetes in a high-risk group of Japanese male workers.
OBJECTIVE The aim of this study was to assess the effectiveness of a new dietary education ( NDE ) program in reducing plasma glucose ( PG ) levels in Japanese male workers at high risk for type 2 diabetes through a r and omized controlled trial . RESEARCH DESIGN AND METHODS We r and omly assigned 173 high-risk men ( mean age , 55 years ) to either the NDE or the  control ( conventional dietary education )  group . Each subject in the NDE group received two individualized interventions especially aim ed at reducing total energy intake at dinner by modifying dietary intake . The control group received conventional group counseling . An " overintake/underintake fraction " for total energy intake was used to measure the status of dietary intake . Our hypothesis was that the NDE group would have a 10 % decrease in 2-h PG 1 year after the start of the education . Outcome measures were compared with ANCOVA by adjusting for baseline values . RESULTS The NDE group had a significantly lower total energy intake at dinner and daily than the control group . The adjusted differences in changes from baseline in the absolute value of the ' overintake/underintake fraction ' were -15.3 % ( 95 % CI -24.6 to -6.0 % , P = 0.002 ) for dinner and -6.0 % ( -9.8 to -2.2 % , P = 0.002 ) for daily [ corrected ] . The NDE group had a decreased 2-h PG after 1 year , whereas that value was increased in the control group . The adjusted difference in the percent change of 2-h PG was significant ( -15.2 % , -22.0 to -8.4 % , P < 0.001 ) . CONCLUSIONS The NDE was shown to reduce glucose levels in high-risk subjects for type 2 diabetes
