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 .
Effects on cardiovascular disease risk of a web-based health risk assessment with tailored health advice: a follow-up study
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
