Arm && Interventions

Group	Intervention	Description
Intervention: mDASHNa-CC app use	mDASHNa App	In addition to usual care, those participants randomized to the intervention group will be offered use of the app.Then, they will load the app in their smartphones and be requested to review educational contents, conduct dietary self-assessment, and monitor blood pressure for 8 weeks.By the end of eight weeks post randomization, seniors will be prompted by phone using an audible alert to complete the app Evaluation Questionnaire on the smartphone, which ascertains likes and dislikes with the app.

Primary Outcome Measures

Name	Time	Method
change of diastolic Blood Pressure from baseline to eight weeks after randomization	eight weeks after randomization	diastolic blood pressures will be measured by the home blood pressure monitor, Omron BP785, whose validity and reliability have been tested
change of Health-related Quality of Life from baseline to eight weeks after randomization	eight weeks after randomization	Health-related quality of life will be measured by Medical Outcomes Study 36-Item Short Form version two. The SF-36v2 required ten minutes to complete and consisted of 36 items and eight domains, which could be grouped into physical and mental component summaries. All domains were scored on a scale ranging from 0 to 100, wherein 0 represented the worst overall health status and 100 the best health status.
change of systolic Blood Pressure from baseline to eight weeks after randomization	eight weeks after randomization	Systolic blood pressures will be measured by the home blood pressure monitor, Omron BP785, whose validity and reliability have been tested
change of body weight from baseline to eight weeks after randomization	eight weeks after randomization	Weight will be measured by an electronic body weight scale (Rubbermaid® Digital Utility Scale, Model number H-479, Capacity/Accuracy 400 lbs \* 0.5 lb)
change of waist circumference from baseline to eight weeks after randomization	eight weeks after randomization	Waist circumference will be measured by measurement tape following proper technique
