    Input: Abstract Background Diabetes prevalence is increasing . The Finnish Diabetes Prevention Study ( DPS ) showed a 58 % reduction in Type 2 Diabetes ( T2D ) incidence in adults with impaired glucose tolerance ( IGT ) . The European Diabetes Prevention Study ( EDIPS ) extends the DPS to different European population s , using the same study design . In the Newcastle arm of this study ( EDIPS-Newcastle ) , we tested the hypothesis that T2D can be prevented by lifestyle intervention and explored secondary outcomes in relation to diabetes incidence . Methods We recruited 102 participants ( 42 men and 60 women , mean age 57 years , mean BMI 34 kgm-2 ) with IGT to EDIPS-Newcastle and r and omised to Intervention and usual care Control groups .  The intervention included individual motivational interviewing aim ed at : weight reduction , increase in physical activity , fibre and carbohydrate intake and reduction of fat intake ( secondary outcomes ) . The primary outcome was diagnosis of T2D . Results Mean duration of follow-up was 3.1 years . T2D was diagnosed in 16 participants ( I = 5 , C = 11 ) . Absolute incidence of T2D was 32.7 per 1000 person-years in the Intervention-group and 67.1 per 1000 person-years in the Control-group . The overall incidence of diabetes was reduced by 55 % in the Intervention-group , compared with the Control-group : RR 0.45 ( 95%CI 0.2 to 1.2).Explanatory survival analysis of secondary outcomes showed that those who sustained beneficial changes for two or more years reduced their risk of developing T2D . Conclusion Our results are consistent with other diabetes prevention trials . This study was design ed as part of a larger study and although the sample size limits statistical significance , the results contribute to the evidence that T2D can be prevented by lifestyle changes in adults with IGT . In explanatory analysis small sustained beneficial changes in weight , physical activity or dietary factors were associated with reduction in T2D incidence . Trial Registration International St and ard R and omised Controlled Trial Number registry ( IS RCT N)Registry number : IS RCT N 15670600 http://www.controlled-trials.com/is rct n/ search .html?srch=15670600%26sort=3%26dir = BACKGROUND Since the Diabetes Prevention Project ( DPP ) demonstrated that lifestyle weight-loss interventions can reduce the incidence of diabetes by 58 % , several studies have translated the DPP methods to public health-friendly context s. Although these studies have demonstrated short-term effects , no study to date has examined the impact of a translated DPP intervention on blood glucose and adiposity beyond 12 months of follow-up . PURPOSE To examine the impact of a 24-month , community-based diabetes prevention program on fasting blood glucose , insulin , insulin resistance as well as body weight , waist circumference , and BMI in the second year of follow-up . DESIGN An RCT comparing a 24-month lifestyle weight-loss program ( LWL ) to an enhanced usual care condition ( UCC ) in participants with prediabetes ( fasting blood glucose=95 - 125 mg/dL ) . Data were collected in 2007 - 2011 ; analyses were conducted in 2011 - 2012 . SETTING / PARTICIPANTS 301 participants with prediabetes were r and omized ; 261 completed the study . The intervention was held in community-based sites . INTERVENTION The LWL program was led by community health workers and sought to induce 7 % weight loss at 6 months that would be maintained over time through decreased caloric intake and increased physical activity . The UCC received two visits with a registered dietitian and a monthly newsletter . MAIN OUTCOME MEASURES The main measures were fasting blood glucose , insulin , insulin resistance , body weight , waist circumference , and BMI . RESULTS Intent-to-treat analyses of between-group differences in the average of 18- and 24-month measures of outcomes ( controlling for baseline values ) revealed that the LWL participants experienced greater decreases in fasting glucose ( -4.35 mg/dL ) ; insulin ( -3.01 μU/ml ) ; insulin resistance ( -0.97 ) ; body weight ( -4.19 kg ) ; waist circumference ( -3.23 cm ) ; and BMI ( -1.40 ) , all p-values < 0.01 . CONCLUSIONS A diabetes prevention program administered through an existing community-based system and delivered by community health workers is effective at inducing significant long-term reductions in metabolic indicators and adiposity OBJECTIVE To study the overall effect of the Active Prevention in High-Risk Individuals of Diabetes Type 2 in and Around Eindhoven ( APHRODITE ) lifestyle intervention on type 2 diabetes risk reduction in Dutch primary care after 0.5 and 1.5 years and to evaluate the variability between general practice s. RESEARCH DESIGN AND METHODS Individuals at high risk for type 2 diabetes ( Finnish Diabetes Risk Score ≥13 ) were r and omly assigned into an intervention group ( n = 479 ) or a usual-care group ( n = 446 ) . Comparisons were made between study groups and between general practice s regarding changes in clinical and lifestyle measures over 1.5 years . Participant , general practitioner , and nurse practitioner characteristics were compared between individuals who lost weight or maintained a stable weight and individuals who gained weight . RESULTS Both groups showed modest changes in glucose values , weight measures , physical activity , energy intake , and fiber intake . Differences between groups were significant only for total physical activity , saturated fat intake , and fiber intake . Differences between general practice s were significant for BMI and 2-h glucose but not for energy intake and physical activity . In the intervention group , the nurse practitioners ’ mean years of work experience was significantly longer in individuals who were successful at losing weight or maintaining a stable weight compared with unsuccessful individuals . Furthermore , successful individuals more often had a partner . CONCLUSIONS Risk factors for type 2 diabetes could be significantly reduced by lifestyle counseling in Dutch primary care . The small differences in changes over time between the two study groups suggest that additional intervention effects are modest . In particular , the level of experience of the nurse practitioner and the availability of partner support seem to facilitate intervention success The purpose of the present study was to evaluate the impact of a lifestyle intervention programme , combined with a daily low-glycaemic index meal replacement , on body-weight and glycaemic control in subjects with impaired glucose regulation ( IGR ) . Subjects with IGR were r and omly assigned to an intervention group ( n 46 ) and a control group ( n 42 ) . Both groups received health counselling at baseline . The intervention group also received a daily meal replacement and intensive lifestyle intervention to promote healthy eating habits during the first 3 months of the study , and follow-up visits performed monthly until the end of the 1-year study . Outcome measurements included changes in plasma glucose , glycated Hb ( HbA1c ) , plasma lipids , body weight , blood pressure and body composition ( such as body fat mass and visceral fat area ) . The results showed that body-weight loss after 1 year was significant in the intervention group compared with the control group ( -1·8 ( SEM 0·35 ) v. -0·6 ( SEM 0·40 ) 2·5 kg , P<0·05 ) . The 2 h plasma glucose concentration decreased 1·24 mmol/l in the intervention group and increased 0·85 mmol/l in the control group ( P<0·05 ) compared with their baseline , respectively . A 5 kg body-weight loss at 1 year was associated with a decrease of 1·49 mmol/l in 2 h plasma glucose ( P<0·01 ) . The incidence of normal glucose regulation ( NGR ) in the two groups was significantly different ( P=0·001 ) . In conclusion , the combination of regular contact , lifestyle advice and meal replacement is beneficial in promoting IGR to NGR Prevention of type 2 diabetes by intensive lifestyle intervention design ed to achieve and maintain ideal body weight was assessed in subjects with impaired glucose tolerance ( IGT ) . Male subjects with IGT recruited from health-screening examinees were r and omly assigned in a 4:1 ratio to a st and ard intervention group ( control group ) and intensive intervention group ( intervention group ) . The final numbers of subjects were 356 and 102 , respectively . The subjects in the control group and in the intervention group were advised to maintain body mass index ( BMI ) of < 24.0 kg/m2 and of < 22.0 kg/m2 , respectively , by diet and exercise . In the intervention group , detailed instructions on lifestyle were repeated every 3 - 4 months during hospital visits . Diabetes was judged to have developed when two or more consecutive fasting plasma glucose ( FPG ) values exceeded 140 mg/dl . A 100 g oral glucose tolerance test was performed every 6 months to detect improvement of glucose tolerance . The subjects were seen in an ordinary outpatient clinic . The cumulative 4-year incidence of diabetes was 9.3 % in the control group , versus 3.0 % in the intervention group , and the reduction in risk of diabetes was 67.4 % ( P < 0.001 ) . Body weight decreased by 0.39 kg in the control group and by 2.18 kg in the intervention group ( P < 0.001 ) . The control group was subclassified according to increase and decrease in body weight . The incidence of diabetes was positively correlated with the changes in body weight , and the improvement in glucose tolerance was negatively correlated . Subjects with higher FPG at baseline developed diabetes at a higher rate than those with lower FPG . Higher 2h plasma glucose values and higher BMI values at baseline were also associated with a higher incidence of diabetes , but the differences were not significant . Subjects with a low insulinogenic index ( DeltaIRI/DeltaPG 30 min after an oral glucose load ) developed diabetes at a significantly higher rate than those with a normal insulinogenic index . Comparison of the BMI data and incidence of diabetes in five diabetes prevention studies by lifestyle intervention revealed a linear correlation between the incidence of diabetes and the BMI values , with the exception of the DaQing Study . However , the slope of the reduction in incidence of diabetes in the intensive intervention groups was steeper than expected simply on the basis of the reduction of BMI , suggesting that the effect of lifestyle intervention can not be solely ascribed to the body weight reduction . We conclude that lifestyle intervention aim ed at achieving ideal body weight in men with IGT  is effective and can be conducted in an outpatient clinic setting BACKGROUND The Diabetes Prevention Program ( DPP ) lifestyle intervention reduced the incidence of type 2 diabetes mellitus ( DM ) among high-risk adults by 58 % , with weight loss as the dominant predictor . However , it has not been adequately translated into primary care . METHODS We evaluated 2 adapted DPP lifestyle interventions  among overweight or obese adults who were recruited from 1 primary care clinic and had pre-DM and /or metabolic syndrome . Participants were r and omized to ( 1 ) a coach-led group intervention ( n = 79 ) , ( 2 ) a self-directed DVD intervention ( n = 81 ) , or ( 3 ) usual care ( n = 81 ) . During a 3-month intensive intervention phase , the DPP-based behavioral weight-loss curriculum was delivered by lifestyle coach-led small groups or home-based DVD . During the maintenance phase , participants in both interventions received lifestyle change coaching and support remotely-through secure email within an electronic health record system and the American Heart Association Heart360 website for weight and physical activity goal setting and self-monitoring . The primary outcome was change in body mass index ( BMI ) ( calculated as weight in kilograms divided by height in meters squared ) from baseline to 15 months . RESULTS At baseline , participants had a mean ( SD ) age of 52.9 ( 10.6 ) years and a mean BMI of 32.0 ( 5.4 ) ; 47 % were female ; 78 % , non-Hispanic white ; and 17 % , Asian/Pacific Isl and er . At month 15 , the mean ± SE change in BMI from baseline was -2.2 ± 0.3 in the coach-led group vs -0.9 ± 0.3 in the usual care group ( P < .001 ) and -1.6 ± 0.3 in the self-directed group vs usual care ( P = .02 ) . The percentages of participants who achieved the 7 % DPP-based weight-loss goal were 37.0 % ( P = .003 ) and 35.9 % ( P = .004 ) in the coach-led and self-directed groups , respectively , vs 14.4 % in the usual care group . Both interventions also achieved greater net improvements in waist circumference and fasting plasma glucose level . CONCLUSION Proven effective in a primary care setting , the 2 DPP-based lifestyle interventions are readily scalable and exportable with potential for substantial clinical and public health impact .

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 .
