    Input: OBJECTIVE To test whether a theory-based , literacy , and culturally tailored self-management intervention , Latinos en Control  , improves glycemic control among low-income Latinos with type 2 diabetes . RESEARCH DESIGN AND METHODS A total of 252 patients recruited from community health centers were r and omized to the  Latinos en Control intervention or to usual care . The primarily group-based intervention consisted of 12 weekly and 8 monthly sessions and targeted knowledge , attitudes , and self-management behaviors . The primary outcome was HbA1c . Secondary outcomes included diet , physical activity , blood glucose self-monitoring , diabetes knowledge and self-efficacy , and other physiological factors ( e.g. , lipids , blood pressure , and weight ) . Measures were collected at baseline and at 4- and 12-month follow-up . Change in outcomes over time between the groups and the association between HbA1c and possible mediators were estimated using mixed-effects models and an intention-to-treat approach . RESULTS A significant difference in HbA1c change between the groups was observed at 4 months ( intervention −0.88 [ −1.15 to −0.60 ] versus control −0.35 [ −0.62 to 0.07 ] , P < 0.01 ) , although this difference decreased and lost statistical significance at 12 months ( intervention −0.46 [ −0.77 to −0.13 ] versus control −0.20 [ −0.53 to 0.13 ] , P = 0.293 ) . The intervention result ed in significant change differences in diabetes knowledge at 12 months ( P = 0.001 ) , self-efficacy ( P = 0.001 ) , blood glucose self-monitoring ( P = 0.02 ) , and diet , including dietary quality ( P = 0.01 ) , kilocalories consumed ( P < 0.001 ) , percentage of fat ( P = 0.003 ) , and percentage of saturated fat ( P = 0.04 ) . These changes were in turn significantly associated with HbA1c change at 12 months . CONCLUSIONS Literacy-sensitive , culturally tailored interventions can improve diabetes control among low-income Latinos ; however , strategies to sustain improvements are needed PURPOSE The purpose of this r and omized controlled trial is to determine the effectiveness of an intervention led by promotoras ( community lay workers ) on the glycemic control , diabetes knowledge , and diabetes health beliefs of Mexican Americans with type 2 diabetes living in a major city on the Texas-Mexico border . METHODS One hundred fifty Mexican American participants were recruited at a Catholic faith-based clinic and r and omized into 2 groups . Personal characteristics , acculturation , baseline A1C level , diabetes knowledge , and diabetes health beliefs were measured . The intervention was culturally specific and consisted of participative group education , telephone contact , and follow-up using inspirational faith-based health behavior change postcards . The A1C levels , diabetes knowledge , and diabetes health beliefs were measured 3 and 6 months postbaseline , and the mean change between the groups was analyzed . RESULTS The 80 % female sample , with a mean age of 58 years , demonstrated low acculturation , income , education , health insurance coverage , and strong Catholicism . No significant changes were noted at the 3-month assessment , but the mean change of the A1C levels , F(1 , 148 ) = 10.28 , P < .001 , and the diabetes knowledge scores , F(1 , 148 ) = 9.0 , P < .002 , of the intervention group improved significantly at 6 months , adjusting for health insurance coverage . The health belief scores decreased in both groups . CONCLUSIONS The intervention result ed in decreased A1C levels and increased diabetes knowledge , suggesting that using promotoras as part of an interdisciplinary team can result in positive outcomes for Mexican Americans who have type 2 diabetes . Clinical implication s and recommendations for future research are suggested Background Dealing with heterogeneity in meta-analyses is often tricky , and there is only limited advice for authors on what to do . We investigated how authors addressed different degrees of heterogeneity , in particular whether they used a fixed effect model , which assumes that all the included studies are estimating the same true effect , or a r and om effects model where this is not assumed . Methods We sample d r and omly 60 Cochrane review s from 2008 , which presented a result in its first meta- analysis with substantial heterogeneity ( I2 greater than 50 % , i.e. more than 50 % of the variation is due to heterogeneity rather than chance ) . We extracted information on choice of statistical model , how the authors had h and led the heterogeneity , and assessed the method ological quality of the review s in relation to this . Results The distribution of heterogeneity was rather uniform in the whole I2 interval , 50 - 100 % . A fixed effect model was used in 33 review s ( 55 % ) , but there was no correlation between I2 and choice of model ( P = 0.79 ) . We considered that 20 review s ( 33 % ) , 16 of which had used a fixed effect model , had major problems . The most common problems were : use of a fixed effect model and lack of rationale for choice of that model , lack of comment on even severe heterogeneity and of reservations and explanations of its likely causes . The problematic review s had significantly fewer included trials than other review s ( 4.3 vs. 8.0 , P = 0.024 ) . The problems became less pronounced with time , as those review s that were most recently up date d more often used a r and om effects model . Conclusion One-third of Cochrane review s with substantial heterogeneity had major problems in relation to their h and ling of heterogeneity . More attention is needed to this issue , as the problems we identified can be essential for the conclusions of the review Uncontrolled diabetes is a major health problem in Thail and . The objective of this study was to determine the effects of a diabetes self-management program on glycemic control , coronary heart disease ( CHD ) risk , and quality of life in 147 diabetic patients ( aged 56.8 + /- 10.2 years ) . Type 2 diabetic patients who met the research criteria were r and omized into two groups for a period of 6 months : the experimental group received the diabetes self-management program and the control group received the usual nursing care . The findings indicated that the experimental group demonstrated a significant decrease in the hemoglobin A(1c ) level and CHD risk , with an increase in quality of life ( QOL ) compared to the control group . The diabetes self-management program was effective for improving metabolic control and the QOL for individuals with diabetes . Further studies should be replicated using larger groups over a longer time frame Background Multiple-risk-factor interventions offer a promising means for addressing the complex interactions between lifestyle behaviors , psychosocial factors , and the social environment . This report examines the long-term effects of a multiple-risk-factor intervention . Methods Postmenopausal women ( N = 279 ) with type 2 diabetes participated in the  Mediterranean Lifestyle Program ( MLP ) , a r and omized , comprehensive lifestyle intervention study . The intervention targeted healthful eating , physical activity , stress management , smoking cessation , and social support . Outcomes included lifestyle behaviors ( i.e. , dietary intake , physical activity , stress management , smoking cessation ) , psychosocial variables ( e.g. , social support , problem solving , self-efficacy , depression , quality of life ) , and cost analyses at baseline , and 6 , 12 , and 24 months . Results MLP participants showed significant 12- and 24-month improvements in all targeted lifestyle behaviors with one exception ( there were too few smokers to analyze tobacco use effects ) , and in psychosocial measures of use of supportive re sources , problem solving , self-efficacy , and quality of life . Conclusion The MLP was more effective than usual care over 24 months in producing improvements on behavioral and psychosocial outcomes . Directions for future research include replication with other population AIMS To determine the effects of the Diabetes Manual on glycaemic control , diabetes-related distress and confidence to self-care of patients with Type 2 diabetes . METHODS A cluster r and omized , controlled trial of an intervention group vs. a 6-month delayed-intervention control group with a nested qualitative study . Participants were 48 urban general practice s in the West Midl and s , UK , with high population deprivation levels and 245 adults with Type 2 diabetes with a mean age of 62 years recruited pre-r and omization . The Diabetes Manual is 1:1 structured education design ed for delivery by practice nurses . Measured outcomes were HbA(1c ) , cardiovascular risk factors , diabetes-related distress measured by the Problem Areas in Diabetes Scale and confidence to self-care measured by the Diabetes Management Self-Efficacy Scale . Outcomes were assessed at baseline and 26 weeks . RESULTS There was no significant difference in HbA(1c ) between the intervention group and the control group [ difference -0.08 % , 95 % confidence interval ( CI ) -0.28 , 0.11 ] . Diabetes-related distress scores were lower in the intervention group compared with the control group ( difference -4.5 , 95 % CI -8.1 , -1.0 ) . Confidence to self-care Scores were 11.2 points higher ( 95 % CI 4.4 , 18.0 ) in the intervention group compared with the control group . The patient response rate was 18.5 % . CONCLUSIONS In this population , the Diabetes Manual achieved a small improvement in patient diabetes-related distress and confidence to self-care over 26 weeks , without a change in glycaemic control . Further study is needed to optimize the intervention and characterize those for whom it is more clinical ly and psychologically effective to support its use in primary care Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more Objective To measure whether the benefits of a single education and self management structured programme for people with newly diagnosed type 2 diabetes mellitus are sustained at three years . Design Three year follow-up of a multicentre cluster r and omised controlled trial in primary care , with r and omisation at practice level . Setting 207 general practice s in 13 primary care sites in the United Kingdom . Participants 731 of the 824 participants included in the original trial were eligible for follow-up . Biomedical data were collected on 604 ( 82.6 % ) and question naire data on 513 ( 70.1 % ) participants . Intervention A structured group education programme for six hours delivered in the community by two trained healthcare professional educators compared with usual care . Main outcome measures The primary outcome was glycated haemoglobin ( HbA1c ) levels . The secondary outcomes were blood pressure , weight , blood lipid levels , smoking status , physical activity , quality of life , beliefs about illness , depression , emotional impact of diabetes , and drug use at three years . Results HbA1c levels at three years had decreased in both groups . After adjusting for baseline and cluster the difference was not significant ( difference −0.02 , 95 % confidence interval −0.22 to 0.17 ) . The groups did not differ for the other biomedical and lifestyle outcomes and drug use . The significant benefits in the intervention group across four out of five health beliefs seen at 12 months were sustained at three years ( P<0.01 ) . Depression scores and quality of life did not differ at three years . Conclusion A single programme for people with newly diagnosed type 2 diabetes mellitus showed no difference in biomedical or lifestyle outcomes at three years although there were sustained improvements in some illness beliefs . Trial registration Current Controlled Trials IS RCT N17844016 AIM Patient education that enhances one 's self-management ability is of utmost importance for improving patient outcomes in chronic diseases . We developed a 12 month self-management education program for type 2 diabetes , based on a previous 6 month program , and examined its efficacy . METHODS A r and omized controlled trial was carried out on out patients with type 2 diabetes from two hospitals who met the criteria and gave consent to participate . They were r and omly divided into an intervention group that followed the program and a control group that followed usual clinical practise . The intervention group received < 30 min of monthly interviews based on the program 's textbook and biweekly telephone calls from a nurse educator throughout the 12 months . RESULTS Of the 50 participants in the intervention group and the 25 participants in the control group , 42 and 23 , respectively , completed the program ( a completion rate of 84.0 % ) . The body weight , HbA1c , self-efficacy , dietary and exercise stages , quality of life , diastolic blood pressure , and total cholesterol level were significant by two-way repeated- measures anova . As for changes over time within the groups , only the intervention group showed significant differences by Friedman 's test . The complication prevention behaviors showed a high implementation rate in the intervention group . The overall evaluation of this program by the participants was very high and , therefore , they highly recognized the need for this type of program . CONCLUSIONS Self-management education works successfully in relation to patients ' behavior modification skills , degree of goal attainment , and self-efficacy , consequently improving their health outcomes The aim of the present study was to evaluate the impact of empowerment group education on  type 2 diabetes patients '  confidence in diabetes knowledge , self-efficacy , satisfaction with daily
