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 .
Using an online, personalized program reduces cardiovascular risk factor profiles in a motivated, adherent population of participants.
BACKGROUND Cardiovascular disease ( CVD ) is the leading cause of morbidity , mortality , and cost in Western society . Employer-sponsored work health programs ( WHPs ) and Web-based portals for monitoring and providing guidance based on participants ' health risk assessment s are emerging , yet online technologies to improve CVD health in the workplace are relatively unproven . We hypothesized that an online WHP , comprehensively addressing multiple facets of CVD , can be successfully implemented and improve the health of participants . METHODS A cohort of employees in Tennessee ( n = 1,602 ) was subjected to a health risk assessment at baseline . Those who did not meet all 5 healthy benchmarks ( n = 836)-body mass index , blood pressure , glucose , total cholesterol , and smoking status-were prospect ively assigned to a Web-based personal health assistant and had repeat measurements taken at 90 days . RESULTS Of those who both completed the personal health assistant program and underwent baseline plus 90-day assessment s ( 508/836 , 61 % ) , 75 % were female , mean age was 46.5 ± 11.1 years , and the mean number of risk factors  at baseline was 1.1 ± 0.9 with a mean 10-year Framingham Risk Score of 2.9 % . This cohort demonstrated a significant reduction in total cholesterol ( P < .0001 ) , low-density lipoprotein cholesterol ( P < .0001 ) , triglycerides ( P < .0001 ) , systolic blood pressure ( P = .009 ) , glucose ( P = .004 ) , weight ( P = .001 ) , and body mass index ( P = .001 ) . Most of the participants improved at least 1 risk factor . Framingham Risk 10-year cardiovascular risk percentages were significantly reduced ( P = .003 ) . CONCLUSIONS This study in a prospect i ve cohort of community-dwelling employees suggests that an online WHP can provide a viable means to improve surrogates of CVD risk factors
