Overall , these aggregations of data provide evidence that DHIs can reduce CVD outcomes and have a positive impact on risk factors for CVD
OBJECTIVE To assess the potential benefit of digital health interventions ( DHIs ) on  cardiovascular disease ( CVD ) outcomes ( CVD events , all-cause mortality , hospitalizations ) and risk factors compared with non-DHIs .
Comparative effectiveness of weight-loss interventions in clinical practice.
BACKGROUND Obesity and its cardiovascular complications are extremely common medical problems , but evidence on how to accomplish weight loss in clinical practice is sparse . METHODS We conducted a r and omized , controlled trial to examine the effects of two behavioral weight-loss interventions in 415 obese patients with at least one cardiovascular risk factor . Participants were recruited from six primary care practice s ; 63.6 % were women , 41.0 % were black , and the mean age was 54.0 years . One intervention provided patients with weight-loss support remotely -- through the telephone , a study -specific Web site , and e-mail . The other intervention provided in-person support during group and individual sessions , along with the three remote means of support . There was also a control group in which weight loss was self-directed . Outcomes were compared between each intervention group and the control group and between the two intervention groups . For both interventions , primary care providers reinforced participation at routinely scheduled visits . The trial duration was 24 months . RESULTS At baseline , the mean body-mass index ( the weight in kilograms divided by the square of the height in meters ) for all participants was 36.6 , and the mean weight was 103.8 kg . At 24 months , the mean change in weight from baseline was -0.8 kg in the control group , -4.6 kg in the group receiving remote support only ( P<0.001 for the comparison with the control group ) , and -5.1 kg in the group receiving in-person support ( P<0.001 for the comparison with the control group ) . The percentage of participants who lost 5 % or more of their initial weight was 18.8 % in the control group , 38.2 % in the group receiving remote support only , and 41.4 % in the group receiving in-person support . The change in weight from baseline did not differ significantly between the two intervention groups . CONCLUSIONS In two behavioral interventions , one delivered with in-person support and the other delivered remotely , without face-to-face contact between participants and weight-loss coaches , obese patients achieved and sustained clinical ly significant weight loss over a period of 24 months .
