HDS-9.1 Data Details

Expand All

HDS-9.1 Increase the proportion of adults with prehypertension who meet the recommended guidelines for body mass index (BMI)

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Health and Nutrition Examination Survey
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent (age adjusted—see Comments)
Baseline (Year): 
28.7 (2005–08)
Target: 
33.0
Target-Setting Method: 
Minimal statistical significance
Target-Setting Method Justification: 
The target value of 33 percent represents the smallest change that will result in a statistically meaningful improvement over the baseline value and would yield a realistic, probably attainable target value.
Numerator: 

Number of persons aged 18 years and over, excluding pregnant women, with prehypertension with a BMI equal to or greater than 18.5 and less than 25.0

Denominator: 

Number of persons aged 18 years and over, excluding pregnant women, with prehypertension

Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Periodic
Methodology Notes: 

    The NHANES obtains measured weights and heights without shoes. BMI is calculated by dividing weight in kilograms by the square of height in meters.

    For blood pressure management among persons with prehypertension it is recommended that they maintain a normal body weight (BMI 18.5-24.9 kg/m²). Systolic blood pressure is reduced by approximately 5–20 mmHg/10kg.

    Adults are defined as having prehypertension if they do not report that they are taking high blood pressure medicine and either: (a) have a measurement of mean systolic blood pressure (SBP) ≥120 and <140 mm Hg or (b) mean diastolic blood pressure (DBP) ≥80 and <90 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.
