Brief summary
The aim of this proposed study is to translate the Dietary Approach to Stop Hypertension with Sodium (Na) Reduction for Chinese Canadian (DASHNa-CC), a classroom-based antihypertensive dietary educational intervention, to an innovative smartphone app (mDASHNa-CC) to enable Chinese Canadian seniors' access to this antihypertensive dietary intervention anytime, regardless of where they are.
Interventions
DEVICEmDASHNa App
The functions of the app will include: (a) antihypertensive dietary education; (b) dietary self-assessment; (c) automatic feedback according to dietary self-assessment; (d) blood pressure monitoring; and (e) automatic feedback according to blood pressure data.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 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 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 |
| 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. |
