Study Population

A follow-up genetic study of Taiwan SAPPHIRe Cohort

You may qualify if:

  • Age of subjects when recruited must be between 35 and 60 years. Subjects over age 60 may also be eligible provided that documentation of their hypertension status prior to age 60 is available.
  • Chinese ancestry, i.e. all four grandparents Chinese. Hypertension is defined as follows: systolic BP (SBP) greater than or equal to (\>=) 160 mm Hg or diastolic BP (DBP) \>= 95 mm Hg or taking 2 medications for high blood pressure (Stage II hypertension). Alternatively the subject could have uncontrolled hypertension, i.e. taking 1 medication for high blood pressure and has either systolic BP \>= 140 or diastolic \>= 90 mm Hg.

You may not qualify if:

  • One of the affected sibs is adopted (i.e. no parent in common) or if the sibs have only one parent in common.
  • A body-mass index greater than 35.
