From the Strong Heart Study


Calculator: Estimated Risk of Developing Hypertension in the next 4 Years


The risk calculator below uses research data from the Strong Heart Study (Citation: Wang et al. Hypertension. 2006;47:403-409 ) to estimate the risk for a non-hypertensive person to develop hypertension in the next 4 years. It is designed for American Indians of age 35 and older. This calculator is not intended for clinicians but rather serves as a tool for research and community planning. To find your estimated risk, enter your information in the calculator below. Definitions and descriptions of some terms in the calculator are provided at the bottom of the calculator.

Predicting risk of developing incident hypertension in the next 4 years for a person who does not currently have hypertension.


Age (year)

Weight (lb)

Height (in)

Systolic blood pressure (SBP) (mmHg)

Diastolic blood pressure (DBP) (mmHg)

Do you currently drink more than two (if male) or one (if female) serving of alcohol per day?

No Yes

Do you have any parents who had hypertension?

No Yes

Are you currently on diabetes medications?

No Yes

Fasting plasma glucose (FPG) (mg/dL)

Do you have micro-albuminuria?

No Yes

Do you have macro-albuminuria?

No Yes

Your Estimated Risk:



Definitions and Descriptions



An incident hypertension event is defined by either having a systolic blood pressure (SBP) >= 140mmHg, or having a distolic blood pressure (DBP) >= 90mmHg.




Albuminuria is defined by urinary albumin and creatinine ratio (UACR) (mg/g). Micro-albuminuria, if 30mg/g <= UACR < 300mg/g; Macro-albuminuria, if 300mg/g <= UACR.



    Your Estimated Risk : This percentage indicates the chance that you will develop hypertension in the next 4 years. For example, if your estimated risk is 20%, it means that 20 out of the 100 people who enter the exact same information as you did in the calculator would likely develop hypertension in the next 4 years.
