The AHA Oneida Study

Number of incidences of stroke or TIA during the study

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.

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.

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.

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.

NIH Toolbox Cognition Battery consists of tests of multiple constructs to asses for cognitive, sensory, motor and emotional function

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.

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

Measured via carotid ultrasound.

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.
