About the National Data
Data
Baseline: 44.8 percent of adults aged 18 years and over with chronic kidney disease had elevated blood pressure in 2013-16
Target: 39.8 percent
Methodology
Chronic kidney disease (CKD) stages 1–4 are defined as a urinary albumin-to-creatinine ratio (ACR) ≥ 30 mg/g (single measurement) or estimated glomerular filtration rate (eGFR) between 15 and 59 ml/min/1.73 m². The eGFR is computed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
Adults are defined as having high blood pressure if they have a measurement of mean systolic blood pressure ≥ 130 mm Hg or mean diastolic blood pressure ≥ 80 mm Hg. Blood pressure is measured by averaging up to 3 blood pressure readings taken during the physical examination in the NHANES Mobile Examination Center. A detailed description of the procedures for blood pressure measurement in the NHANES has been published elsewhere.
History
In 2023, the original baseline was revised from 46.6 to 44.8 percent due to changes to 2021 race free, serum creatine only CKD-EPI equation used to determine estimated glomerular filtration rate (eGFR). The target was adjusted from 42.8 to 39.8 percent to reflect the revised baseline using the original target-setting method.
