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 .
Translating the Diabetes Prevention Program Into an Urban Medically Underserved Community
OBJECTIVE —The objective of this study was to determine if a community-based modified Diabetes Prevention Program Group Lifestyle Balance ( GLB ) intervention , for individuals with metabolic syndrome , was effective in decreasing risk for type 2 diabetes and cardiovascular disease ( CVD ) in an urban medically underserved community , and subsequently to determine if improvements in clinical outcomes could be sustained in the short term . RESEARCH DESIGN AND METHODS —This nonr and omized prospect i ve intervention study used a one-group design to test the effectiveness of a community-based GLB intervention .  Residents from 11 targeted neighborhoods were screened for metabolic syndrome ( n = 573 ) and took part in a 12-week GLB intervention ( n = 88 ) that addressed safe  weight loss and physical activity . RESULTS —A marked decline in weight ( 46.4 % lost ≥5 % and 26.1 % lost ≥7 % ) was observed in individuals after completion of the intervention . Of these subjects , 87.5 % ( n = 28 ) and 66.7 % ( n = 12 ) sustained the 5 % and 7 % reduction , respectively , at the 6-month re assessment . Over one-third of the population ( 43.5 % , n = 30 ) experienced improvements in one or more component of metabolic syndrome , and 73.3 % ( n = 22 ) sustained this improvement at the 6-month re assessment . Additional improvements occurred in waist circumference ( P < 0.009 ) and blood pressure levels ( P = 0.04 ) after adjustment for age , sex , race , mean number of GLB classes attended , and time . CONCLUSIONS —Adults in an urban medically underserved community can decrease their risk for type 2 diabetes and CVD through participation in a GLB intervention , and short-term sustainability is feasible . Future research will include long-term follow-up of these subjects
