Abstract
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 researchers 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 pUnder0 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 pUnder0 05 and 2 8 cm pUnder0 05 in the intervention group respectively In the control group increases in body weight and waist circumference pUnder0 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 pUnder0 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
