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 .
Effect of a cardiovascular prevention program on health behavior and BMI in highly educated adults: a randomized controlled trial.
OBJECTIVE To examine the effects and dose-response effects of an intervention on health behavior ( fat intake , physical activity , and smoking ) and Body Mass Index ( BMI ) in a sample of highly educated adults . METHODS Participants were r and omized to a ' usual care ' condition ( = medical assessment ) ( n=106 ) and an intervention condition ( = cardiovascular prevention program )  that additionally included a website and one-on-one coaching ( by e-mail , telephone , and /or face-to-face ) ( n=208 ) . The participants could select their own intervention dose and delivery mode . RESULTS Participants completed question naires at baseline ( n=93 ; n=194 ) and 6 months post-baseline ( n=84 ; n=168 ) . The intervention was not more effective than ' usual care ' but a higher intervention dose led to better outcomes for fat intake and physical activity , independent of baseline motivation . Furthermore , the effect of combining different delivery modes was dependent on the behavioral context . CONCLUSION A higher intervention dose led to better results but allowing people to select their own intervention dose probably undermined the potential intervention effect . PRACTICE IMPLICATION S The present study highlights the importance of intervention dose and delivery mode for the development , evaluation , and optimization of health promotion programs
