About the National Data

Data

Data Source:  National Health and Nutrition Examination Survey (NHANES), CDC/NCHS

Baseline: 46.6 percent of adults aged 18 years and over with chronic kidney disease had elevated blood pressure in 2013-16

Target: 42.8 percent

Numerator
Number of adults aged 18 years and over with chronic kidney disease stages 1–4 with measured high systolic (≥130 mmHg) or diastolic (≥80 mmHg) blood pressure.
Denominator
Number of adults aged 18 years and over with chronic kidney disease stages 1–4 who have blood pressure measurements.
Target-setting method

Minimal statistical significance

Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were not available for this objective. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because the target is a statistically significant improvement from the baseline. This conservative target was selected because of the lower threshold definition of high blood pressure in the more recent patient care recommendations.

Methodology

Methodology notes

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

Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People objective CKD-6.1 in that objective CKD-6.1 tracked persons with chronic kidney disease stages 1-4 with measured systolic (≥ 140 mmHg) or diastolic (≥ 90mmHg) blood pressure, while this objective tracks persons with chronic kidney disease stages who had measured systolic (≥ 130mmHg) or diastolic (≥ 80 mmHg) blood pressure
