    Input: Background : The prevalence of type 2 diabetes and diabetesrelated morbidity and mortality is higher among low-income Hispanics when compared to that of Whites . However , little is known about how to effectively promote self-management in this population . Purpose : The objectives were first to determine the feasibility of conducting a r and omized clinical trial of an innovative self-management intervention to improve metabolic control in low-income Spanish-speaking individuals with type 2 diabetes and second to obtain preliminary data of possible intervention effects . Methods : Participants for this pilot study were recruited from a community health center , an elder program , and a community-wide data base developed by the community health center , in collaboration with other agencies serving the community , by surveying households in the entire community . Participants were r and omly assigned to an intervention  ( n = 15 ) or a control ( n = 10 ) condition . Assessment s were conducted at baseline and at 3 months and 6 months postr and omization . The intervention consisted of 10 group sessions that targeted diabetes knowledge , attitudes , and self-management skills through culturally specific and literacysensitive strategies . The intervention used a cognitivebehavioral theoretical framework . Results : Recruitment rates at the community health center , elder program , and community registry were 48 % , 69 % , and 8 % , respectively . Completion rates for baseline , 3-month , and 6-month assessment s were 100 % , 92 % , and 92 % , respectively . Each intervention participant attended an average of 7.8 out of 10 sessions , and as a group the participants showed high adherence to intervention activities ( 93 % turned in daily logs , and 80 % self-monitored glucose levels at least daily ) . There was an overall Group × Time interaction ( p = .02 ) indicating group differences in glycosylated hemoglobin over time . The estimated glycosylated hemoglobin decrease at 3 months for the intervention group was −0.8 % ( 95 % confidence intervals = −1.1 % , −0.5 % ) compared with the change in the control group ( p = .02 ) . At 6 months , the decrease in the intervention group remained significant , −0.85 % ( 95 % confidence intervals = −1.2 , −0.5 ) , and the decrease was still significantly different from that of the controls ( p = .005 ) . There was a trend toward increased physical activity in the intervention group as compared to that of the control group ( p = .11 ) and some evidence ( nonsignificant ) of an increase in blood glucose self-monitoring in the intervention participants but not the control participants . Adjusting for baseline depressive scores , we oberved a significant difference in depressive symptoms between intervention participants and control participants at the 3-month assessment ( p = .02 ) . Conclusions : Low-income Spanish-speaking Hispanics are receptive to participate in diabetes-related research . This study shows that the pilot-tested diabetes self-management program is promising and warrants the conduct of a r and omized clinical trial BACKGROUND Patients with depression and poorly controlled diabetes , coronary heart disease , or both have an increased risk of adverse outcomes and high health care costs . We conducted a study to determine whether coordinated care management of multiple conditions improves disease control in these patients . METHODS We conducted a single-blind , r and omized , controlled trial in 14 primary care clinics in an integrated health care system in Washington State , involving 214 participants with poorly controlled diabetes , coronary heart disease , or both and coexisting depression . Patients were r and omly assigned to the usual-care group or to the intervention group , in which a medically supervised nurse , working with each patient 's primary care physician , provided guideline -based , collaborative care management , with the goal of controlling risk factors associated with multiple diseases . The primary outcome was based on simultaneous modeling of glycated hemoglobin , low-density lipoprotein ( LDL ) cholesterol , and systolic blood-pressure levels and Symptom Checklist-20 ( SCL-20 ) depression outcomes at 12 months ; this modeling allowed estimation of a single overall treatment effect . RESULTS As compared with controls , patients in the intervention group had greater overall 12-month improvement across glycated hemoglobin levels ( difference , 0.58 % ) , LDL cholesterol levels ( difference , 6.9 mg per deciliter [ 0.2 mmol per liter ] ) , systolic blood pressure ( difference , 5.1 mm Hg ) , and SCL-20 depression scores ( difference , 0.40 points ) ( P<0.001 ) . Patients in the intervention group also were more likely to have one or more adjustments of insulin ( P=0.006 ) , antihypertensive medications ( P<0.001 ) , and antidepressant medications ( P<0.001 ) , and they had better quality of life ( P<0.001 ) and greater satisfaction with care for diabetes , coronary heart disease , or both ( P<0.001 ) and with care for depression ( P<0.001 ) . CONCLUSIONS As compared with usual care , an intervention involving nurses who provided guideline -based , patient-centered management of depression and chronic disease significantly improved control of medical disease and depression . ( Funded by the National Institute of Mental Health ; Clinical Trials.gov number , NCT00468676 . ) BACKGROUND Lifestyle changes soon after diagnosis might improve outcomes in patients with type 2 diabetes mellitus , but no large trials have compared interventions . We investigated the effects of diet and physical activity on blood pressure and glucose concentrations . METHODS We did a r and omised , controlled trial in southwest Engl and in adults aged 30 - 80 years in whom type 2 diabetes had been diagnosed 5 - 8 months previously . Participants were assigned usual care ( initial dietary consultation and follow-up every 6 months ; control group ) , an intensive diet intervention ( dietary consultation every 3 months with monthly nurse support ) , or the latter plus a pedometer-based activity programme , in a 2:5:5 ratio . The primary endpoint was improvement in glycated haemoglobin A(1c)(HbA(1c ) ) concentration and blood pressure at 6 months . Analysis was done by intention to treat . This study is registered , number IS RCT N92162869 . FINDINGS Of 593 eligible individuals , 99 were assigned usual care , 248 the diet regimen , and 246 diet plus activity . Outcome data were available for 587 ( 99 % ) and 579 ( 98 % ) participants at 6 and 12 months , respectively . At 6 months , glycaemic control had worsened in the control group ( mean baseline HbA(1c ) percentage 6·72 , SD 1·02 , and at 6 months 6·86 , 1·02 ) but improved in the diet group ( baseline-adjusted difference in percentage of HbA(1c ) -0·28 % , 95 % CI -0·46 to -0·10 ; p=0·005 ) and diet plus activity group ( -0·33 % , -0·51 to -0·14 ; p<0·001 ) . These differences persisted to 12 months , despite less use of diabetes drugs . Improvements were also seen in bodyweight and insulin resistance between the intervention and control groups . Blood pressure was similar in all groups . INTERPRETATION An intensive diet intervention soon after diagnosis can improve glycaemic control . The addition of an activity intervention conferred no additional benefit . FUNDING Diabetes UK and the UK Department of Health OBJECTIVE —We examined the association between depression , measured as either a continuous symptom severity score or a clinical disorder variable , with self-care behaviors in type 2 diabetes . RESEARCH DESIGN AND METHODS —We surveyed 879 type 2 diabetic patients from two primary care clinics using the Harvard Department of Psychiatry/National Depression Screening Day Scale ( H AND S ) , the Summary of Diabetes Self-Care Activities , and self-reported medication adherence . RESULTS —Of the patients , 19 % met the criteria for probable major depression ( H AND S score ≥9 ) , and an additional 66.5 % reported at least some depressive symptoms . After controlling for covariates , patients with probable major depression reported significantly fewer days ' adherent to diet , exercise , and glucose self-monitoring regimens  ( P < 0.01 ) and 2.3-fold increased odds of missing medication doses in the previous week ( 95 % CI 1.5–3.6 , P < 0.001 ) compared with all other respondents . Continuous depressive symptom severity scores were better predictors of nonadherence to diet , exercise , and medications than categorically defined probable major depression . Major depression was a better predictor of glucose monitoring . Among the two-thirds of patients not meeting the criteria for major depression ( H AND S score < 9 , n = 709 ) , increasing H AND S scores were incrementally associated with poorer self-care behaviors ( P < 0.01 ) . CONCLUSIONS —These findings challenge the conceptualization of depression as a categorical risk factor for nonadherence and suggest that even low levels of depressive symptomatology are associated with nonadherence to important aspects of diabetes self-care . Interventions aim ed at alleviating depressive symptoms , which are quite common , could result in significant improvements in diabetes self-care BACKGROUND Type 2 diabetes mellitus is increasingly common , primarily because of increases in the prevalence of a sedentary lifestyle and obesity . Whether type 2 diabetes can be prevented by interventions that affect the lifestyles of subjects at high risk for the disease is not known . METHODS We r and omly assigned 522 middle-aged , overweight subjects ( 172 men and 350 women ; mean age , 55 years ; mean body-mass index [ weight in kilograms divided by the square of the height in meters ] , 31 ) with impaired glucose tolerance to either the intervention group or the control group . Each subject in the intervention group received individualized counseling aim ed at reducing weight , total intake of fat , and intake of saturated fat and increasing intake of fiber and physical activity . An oral glucose-tolerance test was performed annually ; the diagnosis of diabetes was confirmed by a second test . The mean duration of follow-up was 3.2 years . RESULTS The mean ( + /-SD ) amount of weight lost between base line and the end of year 1 was 4.2+/-5.1 kg in the intervention group and 0.8+/-3.7 kg in the control group ; the net loss by the end of year 2 was 3.5+/-5.5 kg in the intervention group and 0.8+/-4.4 kg in the control group ( P<0.001 for both comparisons between the groups ) . The cumulative incidence of diabetes after four years was 11 percent ( 95 percent confidence interval , 6 to 15 percent ) in the intervention group and 23 percent ( 95 percent confidence interval , 17 to 29 percent ) in the control group . During the trial , the risk of diabetes was reduced by 58 percent ( P<0.001 ) in the intervention group . The reduction in the incidence of diabetes was directly associated with changes in lifestyle . CONCLUSIONS Type 2 diabetes can be prevented by changes in the lifestyles of high-risk subjects Brief , cost-effective interventions to promote diabetes self-management are needed . This study evaluated the effects of a brief , regular , proactive , telephone “ coaching ” intervention delivered by paraprofessionals on diabetes adherence , glycemic control , diabetes-related medical symptoms , and depressive symptoms . Therapeutic mechanisms underlying the intervention ’s effect on the primary outcomes were also examined . Adults diagnosed with type 2 diabetes ( N = 62 ) were r and omly assigned to receive the “ coaching ” intervention and treatment as usual , or only treatment as usual . The intervention increased frequency of exercise and feet inspection , improved diet , reduced diabetes medical symptoms , and lowered depressive symptoms . Self-efficacy , reinforcement , and awareness of self-care goals mediated the treatment effect on depression , exercise , and feet inspection , respectively . A brief telephone intervention delivered by paraprofessionals had positive effects on type 2 diabetes patients AIMS To examine prospect ively the association of depression symptoms with subsequent self-care and medication adherence in patients with Type 2 diabetes mellitus . METHODS Two hundred and eight primary care patients with Type 2 diabetes completed the Harvard Department of Psychiatry/National Depression Screening Day Scale ( H AND S ) and the Summary of Diabetes Self-Care Activities ( SDSCA )  at baseline and at follow-up , an average of 9 months later . They also self-reported  medication adherence at baseline and at a follow-up . RESULTS Baseline H AND S scores ranged from 0 to 27 , with a mean score of 5.15 + /- 4.99 . In separate linear regression models that adjusted for baseline self-care , patients with higher levels of depressive symptoms at baseline reported significantly lower adherence to general diet recommendations and specific recommendations for consumption of fruits and vegetables and spacing of carbohydrates ; less exercise ;  and poorer foot care at follow-up ( beta ranging from -0.12 to -0.23 ; P < 0.05 ) . Similarly , each one-point increase in baseline H AND S score was associated with a 1.08-fold increase in the
