Abstract
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 researchers 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
