230 - Effects of a home blood pressure monitoring by mobile phone-based and health service (continuous antihypertensive treatment) in mild hypertension : the Wakayama Health Promotion Study (ID 392)
Abstract
Background and Aims
Effective anti-hypertensive treatment regimens exist; however, treatment adherence rates are poor. To evaluate the efficacy of a new strategy to control blood pressure by interactive mobile phone support and to follow health service of diet, salt and antihypertensive treatment for 4 years in hypertension.
Methods
Study subjects were 657 general individuals who participated in health check-up. In 389 hypertensive subjects, 92 patients（Grade I）who agreed with this study were randomly selected and distributed in three groups :A total of 83 patients completed the study, (1) control group(n=29:C);(2) salt restriction group(n=28:S); (3) exercise group (n=26:E). All patients were measured by a mobile phone-based self-management support system (OMRON, HEM-7251G) for 3 months. We divided and compared by 2 groups with and without health service for 4 years.
Results
After 3months intervention, home blood pressure for 7 days significantly reduced in three groups (G) (p=0.0001). After 4-year, BP significantly reduced in both health-service G. baPWV no changed in health service G, but in non-service G, baPWV significantly increased (1682±323:1762±319 cm/sec, P<0.05). In no hypertensive treatment, Delta baPWV was significantly high than in treatment G (p<0.05). Multiple regression analyses adjusted for age, TG, LDL-C, HbA1c, uric acid and smoking showed that continuous antihypertensive treatment for 4 years was independently determinants of delta PWV.
Conclusions
A home blood pressure monitoring by mobile phone-based self-management support system is effective in mild hypertension. 4-year intervention revealed that health service and continuous antihypertensive treatment were effective in reducing blood pressure and preventing baPWV.
