Native-CHART Native-Controlling Hypertension And Risk Through Technology​

Native-Controlling Hypertension and Risk through Technology (Native-CHART)

aims to improve control of blood pressure and other risk factors for cardiovascular disease in American Indians, Alaska Natives, Native Hawaiians, and Pacific Islanders with diagnosed hypertension. It comprises three community-based intervention projects and four supporting Cores.

We strive to prevent hypertension, especially in our younger generations, by combining modern science and traditional community knowledge

American Indians, Alaska Natives, Native Hawaiians, and Pacific Islanders experience more risk factors for heart disease and related complications than other racial groups in the United States.
But we have promising news. As researchers learn more about preventing and managing hypertension and other risk factors for heart disease and stroke, we improve our ability to help Native populations reduce their risk of these chronic illnesses.

Intervention project highlights:

Blood Pressure-Improving Control among Alaska Native People (BP-ICAN)

Anchorage, Alaska
  • At-home blood pressure monitoring equipment provided to participants.
  • Educational materials and text messages encouraging the achievement and maintenance of a heart-healthy lifestyle.
  • Tools and resources to assist participants in communicating about heart health with their healthcare providers.

Chickasaw Healthy Eating Environments Research Study (CHEERS)

Ada, Oklahoma
  • The innovative “Packed Promise for a Healthy Heart” program provides home delivery of food boxes containing ingredients approved by Dietary Approaches to Stop Hypertension (DASH) to prepare healthy low-salt and traditional Chickasaw meals.
  • Vouchers improve community access to fresh fruits and vegetables.
  • Heart-healthy recipes tailored to traditional Chickasaw diet and culture are available at
  • An interactive, culturally informed mobile walking app, “AYA Homeland Journey,” which was developed by the Chickasaw Nation, is provided (AYA means “to go or to journey” in the Chickasaw language).
  • A Fitbit fitness tracker is also provided to use with the AYA Homeland Journey app.

Engaging Native Hawaiians & Pacific Islanders and Activating Communities to Take Steps (ENACTS)

Seattle, Washington
  • Peer-facilitated educational classes emphasizing heart-healthy eating; traditional Native Hawaiian/Pacific Islander foods; physical activity; and social support.
