This proposed study aims to translate the Dietary Approach Stop Hypertension with Sodium (Na) Reduction for Chinese Canadians (DASHNa-CC), a classroom-based, antihypertensive, dietary educational intervention, an innovative smartphone app (mDASHNa-CC). will enable Canadian seniors access antihypertensive interventions anytime, regardless of where they are. It is hypothesized that senior be satisfied their experiences using mDASHNa-CC and use this could lead decrease in blood pressure improvement health-related quality life.The goal design test usability feasibility smartphone-based support healthy diet hypertension control seniors.A mixed-method two-phase used. The conducted immigrant community Toronto, Ontario, Canada. seniors, who are at least 65 years old, self-identified as Chinese, living Canada, elevated pressure, recruited. In Phase I, we user-centered approach. II, app, including implementation (primary outcomes accrual attrition rates, technical issues, acceptability adherence intervention) preliminary effectiveness (secondary systolic diastolic weight, waist circumference, life, health service utilization), pilot, two-group, randomized controlled trial sample size 60 participants community.The supported by Startup Research Grant from Nipissing University, research ethics application under review university board.The results make several contributions existing literature, illustrating rigorous testing technology self-management community, exploring approach incorporating traditional medicine into chronic illness management minority communities promoting equal current among groups.Clinicaltrials.gov NCT03988894; https://clinicaltrials.gov/ct2/show/NCT03988894.PRR1-10.2196/15545.
