Hypertension
HYPERTENSION
Information on gender, age, race, standing height, weight, body mass index (BMI), waist circumference, blood pressure, complete blood count, and standard biochemistry was collected from the demographics and examination public release files released by NHANES. The weight, standing height, and waist circumference of participants were obtained from the body measure examinations in a standardized way. Race is divided into four categories: Mexican American; non-Hispanic white; non-Hispanic black, and others. BMI is defined as body weight (kilograms) divided by height (meters) squared. Hypertension is identified by systolic blood pressure measurements > 140 mmHg or diastolic blood pressure measurements > 90 mmHg from the blood pressure examination released by NHANES.
