The AHA Oneida Study

November 3, 2026 updated by: University of Wisconsin, Madison

Transforming Risk Factors in a High Stroke Risk Native American Population Through a Cultural Nutritional Program

The purpose of this clinical trial is to learn whether a cultural nutritional program can change stroke risk factors, cognitive decline, and learn how school education programs about nutrition can improve health in the Oneida Nation.

Participants will undergo:

  • A carotid ultrasound
  • Cognitive testing
  • Health assessment
  • Blood work
  • Health wellness coaching

Participants can expect to be in the study for 1 year.

Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The specific aims for this study are: 1) to determine if a cultural nutritional program across generations can change stroke risk factors in the Oneida Nation; 2) to determine if a cultural nutritional program across generations can change vascular cognitive decline in the Oneida Nation; and, 3) determine how structured culturally competent school education programs about nutrition influence knowledge of health. The intervention used is health wellness coaching. All individuals enrolled in this study will have opportunity to interact with an Oneida Nation employed Health wellness coach to find out about Oneida resources that they can use to modify their stroke risk factors.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in knowledge of health through a structured culturally competent school education programs about nutrition
Time Frame: Baseline to 1 year
Baseline to 1 year
Change in incidence of stroke and transient ischemic attack (TIA)
Time Frame: Baseline to 1 year

Number of incidences of stroke or TIA during the study
Baseline to 1 year
Change in number of participants that meet American Heart Association (AHA) Simple Rules for Diastolic Blood Pressure.
Time Frame: Baseline to 1 year

The AHA's simple rules for diastolic blood pressure: Normal = Less than 80 mm Hg; Elevated = Less than 80 mm Hg with a systolic reading of 120-129 mm Hg; Stage 1 Hypertension = 80-89 mm Hg; Stage 2 Hypertension = 90 mm Hg or higher; Hypertensive Crisis = Higher than 120 mm Hg (along with a systolic reading higher than 180 mm Hg). Researchers will be reporting the change in number of participants with diastolic blood pressure <90 mmHg.
Baseline to 1 year
Change in number of participants that meet AHA's Simple Rules for Systolic Blood Pressure.
Time Frame: Baseline to 1 year

The AHA uses these simple rules for systolic blood pressure (the top number): Normal is less than 120, Elevated is 120-129, Stage 1 Hypertension is 130-139, and Stage 2 Hypertension is 140 or higher. A systolic reading of 180 or higher indicates a hypertensive emergency. Researchers will be reporting the change in number of participants with systolic blood pressure <140 mmHg.
Baseline to 1 year
Change in number of participants that meet AHA Simple Rules for Body Mass Index (BMI)
Time Frame: Baseline to 1 year

The AHA uses the following guidelines for Body Mass Index (BMI) in adults:

Underweight = Less than 18.5; Normal Weight = Between 18.5 and 24.9; Overweight = Between 25 and 29.9; and, Obesity = 30 or higher. Researchers will be reporting any improvement in BMI.
Baseline to 1 year
Change in Montreal Cognitive Assessment (MoCA)
Time Frame: Baseline to 1 year

MoCA is scored out of a total of 30 points, with a score of 26 or above generally considered normal. The MoCA assesses various cognitive domains, including memory, visuospatial abilities, language, and executive functions. A lower score indicates potential cognitive impairment, with specific cutoffs for mild (19-23), moderate (10-18), and severe (0-9) impairment.
Baseline to 1 year
Change in NIH Toolbox Score
Time Frame: Baseline to 1 year

NIH Toolbox Cognition Battery consists of tests of multiple constructs to asses for cognitive, sensory, motor and emotional function
Baseline to 1 year
Change in Native American Acculturation Scale (NAAS)
Time Frame: Baseline to 1 year

NAAS is a 20-item questionnaire developed to assess the level of acculturation in Native Americans. It measures an individual's connection to both traditional Native American culture and mainstream American culture. Scores range from a low of 1, indicating low acculturation (or high Native American identity) to a high of 5, indicating high acculturation (or high mainstream American identity), with a score of 3 indicating "bicultural". The NAAS examines areas like identity, language, friendships, behaviors, attitudes, and generational/geographic background.
Baseline to 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in nutrition knowledge
Time Frame: Baseline to 1 year

Change in knowledge will be assessed with pre-test, 1 year post-test of each participant to assess improvement in nutritional knowledge and understanding of healthy food options tied to Oneida culture. This will be assessed through a 10-question multiple choice survey about good versus bad nutrition choices. Participants will select their choices, low score indicates poor nutritional knowledge and high score indicating better understanding for healthy nutrition
Baseline to 1 year
Change in plaque area
Time Frame: Baseline to 1 year

Measured via carotid ultrasound.
Baseline to 1 year
Change in pulsatility index in carotid arteries
Time Frame: Baseline to 1 year

Measured via carotid ultrasound. This index is a unitless measurement calculated: peak systolic velocity - end diastolic velocity, divided by the mean velocity, higher values are thought to represent increased resistance to blood flow.
Baseline to 1 year
