TC led to a greater decrease in systolic and diastolic BP  than UC .
The differences between TC and UC for systolic BP tend to become larger when no treatment modification is applied .
TC seems a valuable tool for hypertension management
There is an increasing interest for using telecare(TC ) in the management of hypertension .
Cellular phone and Internet-based individual intervention on blood pressure and obesity in obese patients with hypertension
PURPOSE The present study evaluated whether an intervention using a short message service ( SMS ) by cellular phone and Internet would improve blood pressure , weight control , and serum lipids of obese patients with hypertension during 8 weeks . METHODS This is a quasi-experimental design with pre- and follow-up tests . Participants were recruited from the family medicine outpatient department of tertiary care hospital located in an urban city of South Korea . Twenty-eight patients were assigned to an intervention group and 21 to a control group . The goal of intervention was to bring blood pressure , body weight , and serum lipids levels close to normal ranges . Patients in the intervention group were requested to record their blood pressure and body weight in a weekly web based diary through the Internet or by cellular phones . The research ers sent optimal recommendations as an intervention to each patient , by both cellular phone and Internet weekly . The intervention was applied for 8 weeks . RESULTS Systolic ( SBP ) and diastolic blood pressures ( DBP ) significantly decreased by 9.1 and 7.2 mmHg respectively at 8 weeks from the baseline in the intervention group ( p<0.05 ) . However , after 8 weeks from the baseline both SBP and DBP in the control group had not changed significantly . Yet , There were significant mean decreases in body weight and waist circumference by 1.6 kg ( p<0.05 ) and 2.8 cm ( p<0.05 ) in the intervention group , respectively . In the control group increases in body weight and waist circumference ( p<0.05 ) mean changes were also significant . High density lipoprotein cholesterol ( HDL-C ) significantly increased , with a mean change of 3.7 mg/dl at 8 weeks from baseline in the intervention group ( p<0.05 ) . The mean change of HDL-C in the control group was , however , not significant . CONCLUSION During 8 weeks using this web-based intervention by way of cellular phone and Internet SMS improved blood pressure , body weight , waist circumference , and HDL-C in patients with obese hypertension
