Brief Summary
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.

Conditions
Outcome Measures
Primary Outcomes (8)
Change in incidence of stroke and transient ischemic attack (TIA)
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.
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.
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)
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)
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
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)
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
Change in knowledge of health through a structured culturally competent school education programs about nutrition
Baseline to 1 year
Secondary Outcomes (3)
Change in nutrition knowledge
Baseline to 1 year
Change in plaque area
Baseline to 1 year
Change in pulsatility index in carotid arteries
Baseline to 1 year
Study Arms (2)
School-age Native Americans
EXPERIMENTALParticipants who are age 7-17 and live with adult parent or guardian will answer a 10 question nutritional knowledge questionnaire.
Adult Native Americans
EXPERIMENTALAdults age 18-85
Interventions
Health wellness coach will provide education and guidance about cultural nutrition
Participants will undergo an ultrasound
Educational program will teach students about healthy Native American food choices
Participants will undergo a cognitive test.
