Chronic disease result of: – Colonization– Cultural hegemony– Lack of access to healthy food sources
![Page 7: Native-Controlling Hypertension And Risk Through Technology … · Peer Educator Dan Pritchard, MEd. Research Coordinator. Casierra Cruz, MPH. Our Team. Asian Counseling and Referral](https://reader034.fdocuments.us/reader034/viewer/2022042305/5ed0c214a5793b252353dc24/html5/thumbnails/7.jpg)
Significance
• Disproportionate burden of hypertension, diabetes, coronary heart disease (CHD), and stroke
• 3 to 4 times more likely to have CHD and stroke
• CHD and stroke 10 years earlier in life
• Mortality for CHD 68% higher and stroke 20% higher
• 30% less likely to have BP under control
• There are ways to control blood pressure and reduce risk for heart disease

SPECIFIC AIMS
![Page 9: Native-Controlling Hypertension And Risk Through Technology … · Peer Educator Dan Pritchard, MEd. Research Coordinator. Casierra Cruz, MPH. Our Team. Asian Counseling and Referral](https://reader034.fdocuments.us/reader034/viewer/2022042305/5ed0c214a5793b252353dc24/html5/thumbnails/9.jpg)
1) At the individual level, to compare within-personchange in BP and secondary outcomes betweenthe intervention and control groups. We expectmore improvement in intervention participants.
![Page 10: Native-Controlling Hypertension And Risk Through Technology … · Peer Educator Dan Pritchard, MEd. Research Coordinator. Casierra Cruz, MPH. Our Team. Asian Counseling and Referral](https://reader034.fdocuments.us/reader034/viewer/2022042305/5ed0c214a5793b252353dc24/html5/thumbnails/10.jpg)
2) At the family level, to evaluate ENACTS’ effects on BPand secondary outcomes as within-person change infamily members who provide primary support, and asmean change in other adult family members who arenot directly engaged in the intervention. We expectmore improvement associated with ENACTS.
![Page 11: Native-Controlling Hypertension And Risk Through Technology … · Peer Educator Dan Pritchard, MEd. Research Coordinator. Casierra Cruz, MPH. Our Team.

3) At the policy level, to evaluate the intervention’s abilityto influence grocery store policy on using labels toclearly identify foods that are low in sodium or high inpotassium, some of which might not be easily identifiedwith existing labels (e.g., fresh produce). We expectENACTS to promote adoption of such policies.

Lessons Learned
• No prior experience participating in research = significant time to recruit groups and explain study procedures
• Lengthy baseline data collection• Heterogeneity of Pacific Islander community =
potential language challenges if only in English• New recruitment sites – Vancouver/Portland,
Everett, Spokane• Capitalize on existing groups• New strategy for Bitesome App
