    Input: Lowering blood pressure reduces cardiovascular risk , yet hypertension is poorly controlled in diabetic patients . In a pilot study we demonstrated that a home blood pressure telemonitoring system , which provided self-care messages on the smartphone of hypertensive diabetic patients immediately after each reading , improved blood pressure control . Messages were based on care paths defined by running averages of transmitted readings . The present study tests the system 's effectiveness in a r and omized , controlled trial in diabetic patients with uncontrolled systolic hypertension . Of 244 subjects screened for eligibility , 110 ( 45 % ) were r and omly allocated to the intervention ( n=55 ) or control ( n=55 ) group , and 105 ( 95.5 % ) completed the 1-year outcome visit . In the intention-to-treat analysis , mean daytime ambulatory systolic blood pressure , the primary end point , decreased significantly only in the intervention group by 9.1±15.6 mmHg ( SD ; P<0.0001 ) , and the mean between-group difference was 7.1±2.3 mmHg ( SE ; P<0.005 ) . Furthermore , 51 % of intervention subjects achieved the guideline recommended target of < 130/80 mmHg compared with 31 % of control subjects ( P<0.05 ) . These improvements were obtained without the use of more or different antihypertensive medications or additional clinic visits to physicians . Providing self-care support did not affect anxiety but worsened depression on the Hospital Anxiety and Depression Scale ( baseline , 4.1±3.76 ; exit , 5.2±4.30 ; P=0.014 ) . This study demonstrated that home blood pressure telemonitoring combined with automated self-care support reduced the blood pressure of diabetic patients with uncontrolled systolic hypertension  and improved hypertension control . Home blood pressure monitoring alone had no effect on blood pressure . Promoting patient self-care may have negative psychological effects Background Overweight ( Body Mass Index [ BMI ] ≥ 25 kg/m2 ) and obesity ( BMI ≥ 30 kg/m2 ) are associated with increased cardiovascular risk , posing a considerable burden to public health . The main aim of this study was to investigate lifestyle intervention effects on cardiovascular risk factors in healthy overweight employees . Methods Participants were 276 healthy overweight employees ( 69.2 % male ; mean age 44.0 years [ SD 9.2 ] ; mean BMI 29.7 kg/m2 [ SD 3.1 ] ) . They were r and omized to one of two intervention groups receiving a six month lifestyle intervention with behavior counseling by phone ( phone group ) or e-mail ( Internet group ) , or to a control group receiving usual care .  Body weight , height , waist circumference , sum of skinfolds , blood pressure , total cholesterol level and predicted aerobic fitness were measured at baseline , at 6 and at 24 months . Regression analyses included the 141 participants with complete data . Results At 6 months a significant favorable effect on total cholesterol level ( -0.2 mmol/l , 95%CI -0.5 to -0.0 ) was observed in the phone group and a trend for improved aerobic fitness ( 1.9 ml/kg/min , 95%CI -0.2 to 3.9 ) in the Internet group . At two years , favorable trends for body weight ( -2.1 kg , 95%CI -4.4 to 0.2 ) and aerobic fitness ( 2.3 ml/kg/min , 95%CI -0.2 to 4.8 ) were observed in the Internet group . Conclusions The intervention effects were independent of the used communication mode . However short-term results were in favor of the phone group and long-term results in favor of the internet group . Thus , we found limited evidence for our lifestyle intervention to be effective in reducing cardiovascular risk in a group of apparently healthy overweight workers . Trial registration IS RCT Background : The CardioFit internet-based expert system was design ed to promote physical activity in patients with coronary heart disease ( CHD ) who were not participating in cardiac rehabilitation . Design : This r and omized controlled trial compared CardioFit to usual care to assess its effects on physical activity following hospitalization for acute coronary syndromes . Methods : A total of 223 participants were recruited at the University of Ottawa Heart Institute or London Health Sciences Centre and r and omly assigned to either  CardioFit  ( n = 115 ) or  usual care ( n = 108 ) . The CardioFit group received a personally tailored physical-activity plan upon discharge from the hospital and access to a secure website for activity planning and tracking . They completed five online tutorials over a 6-month period and were in email contact with an exercise specialist . Usual care consisted of physical activity guidance from an attending cardiologist .  Physical activity was measured by pedometer and self-reported over a 7-day period , 6 and 12 months after r and omization . Results : The CardioFit internet-based physical activity expert system significantly increased objective ly measured ( p = 0.023 ) and self-reported physical activity ( p = 0.047 ) compared to usual care . Emotional ( p = 0.038 ) and physical ( p = 0.031 ) dimensions of heart disease health-related quality of life were also higher with CardioFit compared to usual care . Conclusions : Patients with CHD using an internet-based activity prescription with online coaching were more physically active at follow up than those receiving usual care . Use of the CardioFit program could extend the reach of rehabilitation and secondary -prevention services Introduction : A large proportion of the cardiovascular disease ( CVD ) burden can potentially be prevented by primary prevention programs addressing major causal risk factors . A Web-based health risk assessment ( HRA ) with tailored feedback for individual health promotion is a promising strategy . We evaluated the effect on CVD risk of such a program among employees of a Dutch worksite . Methods : We conducted a prospect i ve follow-up study among 368 employees who voluntarily participated in a Web-based HRA program at a single Dutch worksite in 2008 . The program included a multicomponent HRA through a Web-based electronic question naire , biometrics , and laboratory evaluation . The results were combined with health behavior change theory to generate tailored motivational and educational health advice . On request , a health counseling session with the program physician was available . Follow-up data on CVD risk were collected 1 year after initial participation . The primary outcome was a change in Framingham CVD risk at 6 months relative to baseline . We checked for a possible background effect of an increased health consciousness as a consequence of program introduction at the worksite by comparing baseline measurements of early program participants with baseline measurements of participants who completed the program 6 months later . Results : A total of 176 employees completed follow-up measurements after a mean of 7 months . There was a grade d relation between CVD risk changes and baseline risk , with a relative reduction of 17.9 % ( P = 0.001 ) in the high-risk category ( baseline CVD risk ≥20 % ) . Changes were not explained by additional health counseling , medication , or an increase in health consciousness within the company . Conclusions : Voluntary participation in a Web-based HRA with tailored feedback at the worksite reduced CVD risk by nearly 18 % among participants at high CVD risk and by nearly 5 % among all participants . Web-based HRA could improve CVD risk in similar population s. Future research should focus on the persistence of the effects underlying the CVD risk reduction Objective To investigate whether an internet based , nurse led vascular risk factor management programme promoting self management on top of usual care is more effective than usual care alone in reducing vascular risk factors in patients with clinical ly manifest vascular disease . Design Prospect i ve r and omised controlled trial . Setting Multicentre trial in secondary and tertiary healthcare setting . Participants 330 patients with a recent clinical manifestation of atherosclerosis in the coronary , cerebral , or peripheral arteries and with at least two treatable risk factors not at goal . Intervention Personalised website with an overview and actual status of patients ’ risk factors and mail communication via the website with a nurse practitioner for 12 months ; the intervention combined self management support , monitoring of disease control , and drug treatment . Main outcome measures The primary endpoint was the relative change in Framingham heart risk score after 1 year . Secondary endpoints were absolute changes in the levels of risk factors and the differences between groups in the change in proportion of patients reaching treatment goals for each risk factor . Results Participants ’ mean age was 59.9 ( SD 8.4 ) years , and most patients ( n=246 ; 75 % ) were male . After 1 year , the relative change in Framingham heart risk score of the intervention group compared with the usual care group was −14 % ( 95 % confidence interval −25 % to −2 % ) . At baseline , the Framingham heart risk score was higher in the intervention group than in the usual care group ( 16.1 ( SD 10.6 ) v 14.0 ( 10.5 ) ) , so the outcome was adjusted for the separate variables of the Framingham heart risk score and for the baseline Framingham heart risk score . This produced a relative change of −12 % ( −22 % to −3 % ) in Framingham heart risk score for the intervention group compared with the usual care group adjusted for the separate variables of the score and −8 % ( −18 % to 2 % ) adjusted for the baseline score . Of the individual risk factors , a difference between groups was observed in low density lipoprotein cholesterol ( −0.3 , −0.5 to −0.1 , mmol/L ) and smoking ( −7.7 % , −14.9 % to −0.4 % ) . Some other risk factors tended to improve ( body mass index , triglycerides , systolic blood pressure , renal function ) or tended to worsen ( glucose concentration , albuminuria ) . Conclusion An internet based , nurse led treatment programme on top of usual care for vascular risk factors had a small effect on lowering vascular risk and on lowering of some vascular risk factors in patients with vascular disease . Trial registration Clinical trials NCT00785031 IMPORTANCE Few weight loss treatments produce clinical ly meaningful weight loss outcomes among black women , particularly in the primary care setting . New weight management strategies are necessary for this population . Weight gain prevention might be an effective treatment option , with particular benefits for overweight and class 1 obese black women . OBJECTIVE To compare changes in weight and cardiometabolic risk during a 12-month period among black women r and omized to a primary care-based behavioral weight gain prevention intervention , relative to usual care . DESIGN , SETTING , AND PARTICIPANTS Two-arm r and omized clinical trial ( the Shape Program ) . We recruited patients from a 6-site community health center system . We r and omized 194 overweight and class 1 obese ( body mass index [ calculated as weight in kilograms divided by height in meters squared ] , 25 - 34.9 ) premenopausal black women aged 25 to 44 years . Enrollment began on December 7 , 2009 ; 12- and 18-month assessment s were completed in February and October 2 , 2012 . INTERVENTIONS The medium-intensity intervention included tailored behavior change goals , weekly self-monitoring via interactive voice response , monthly counseling calls , tailored skills training material s , and a gym membership . MAIN OUTCOMES AND MEASURES Twelve-month change in weight and body mass index and maintenance of change at 18 months . RESULTS Participants had a mean age of 35.4 years , a mean weight of 81.1 kg , and a mean body mass index of 30.2 at baseline . Most were socioeconomically disadvantaged ( 79.7 % with educational level less than a college degree ; 74.3 % reporting annual income < $ 30,000 ) . The 12-month weight change was larger among intervention participants ( mean [ SD ] , -1.0 [ 0.5 ] kg ) , relative to usual care ( 0.5 [ 0.5 ] kg ; mean difference , -1.4 kg [ 95 % CI , -2.8 to -0.1 kg ] ; P = .04 ) . At month 12 , 62 % of intervention participants were at or below their baseline weights compared with 45 % of usual-care participants ( P = .03 ) . By 18 months , intervention participants maintained significantly larger changes in weight ( mean difference , -1.7 kg ; 95 % CI , -3.3 to -0.2 kg ) . CONCLUSIONS AND RELEVANCE A medium-intensity primary care-based behavioral intervention demonstrated efficacy for weight gain prevention among socioeconomically disadvantaged black women . A " maintain , do n't gain " approach might be a useful alternative treatment for reducing obesity-associated disease risk among some premenopausal black women .
