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 .
Evaluation of mobile phone and Internet intervention on waist circumference and blood pressure in post-menopausal women with abdominal obesity
PURPOSE The present study evaluated whether an intervention using a short message service ( SMS ) by personal cellular phone and Internet would reduce cardiovascular risk factors in post-menopausal women with abdominal obesity over 12 weeks . METHODS This is a quasi-experimental design with pre and post tests . Participants were recruited from the gynecology outpatient and family medicine departments of a tertiary care hospital located in an urban city of South Korea . Only 67 subjects completed the entire study , 34 in the intervention group and 33 controls . The goal of intervention was to reduce waist circumference ( WC ) , body weight ( BW ) and blood pressure ( BP ) levels . Before the intervention , demographic variables , WC , BW , BP , fasting plasma glucose ( FPG ) and serum lipids were measured as pre-test data . The WC , BW , BP , FPG and serum lipids were measured again 12 weeks later . Patients in the intervention group were requested to record their WC , BW , BP , type and amount of diet and exercise  in a weekly web-based diary through the Internet or by cellular phone . The research ers sent weekly recommendations on diet and exercise as an intervention to each patient , by both cellular phone and Internet . The intervention was applied for 12 weeks . RESULTS WC and BW significantly decreased by 3.0 cm and 2.0 kg , respectively , at 12 weeks compared with the baseline in the intervention group . However , the mean changes in the control group significantly increased by 0.9 cm and 0.7 kg . Systolic BP ( SBP ) and diastolic BP ( DBP ) significantly decreased by 6.5 and 4.6 mmHg in the intervention group , respectively . The mean changes in the control group were not significant in either SBP or DBP . A significant mean decrease in total cholesterol ( TC ) was observed for the intervention group by 12.9 mg/dl , while the control group showed a significant mean increase by 1.5mg/dl . Low-density lipoprotein-cholesterol ( LDL-C ) for the intervention group showed a significant mean decrease 11.3mg/dl . The mean change in the control group was , however , not significant . CONCLUSION Web-based individual intervention using both SMS and Internet improved WC , BW , BP , TC , and LDL-C during 12 weeks in post-menopausal women with abdominal obesity
