HDS-9.4 Increase the proportion of adults with prehypertension who meet the recommended guidelines for physical activity

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): 
37.4 (2007–10)
Target: 
42.1
Target-Setting Method: 
Minimal statistical significance
Target-Setting Method Justification: 
The target value of 42.1 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 who report moderate physical activity for at least 150 minutes per week or vigorous physical activity for at least 75 minutes per week or an equivalent combination

Denominator: 

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

Comparable Healthy People 2010 Objective: 
Not applicable
Questions Used to Obtain the National Baseline Data:

Methodology Notes: 

    For blood pressure management among persons with prehypertension it is recommended that they engage in regular aerobic physical activity as defined by the Federal physical activity guidelines. Adults are classified as meeting the objective if they participate in at least 150 minutes of moderate activity per week (including walking or biking for transportation), 75 minutes of vigorous activity, or 150 minutes per week of an equivalent combination of activity. Total minutes per week of moderate-intensity activity are calculated by multiplying the days per week adults report participating in moderate-intensity activity by the number of minutes reported. Total minutes per week of vigorous-intensity activity are calculated by multiplying the days per week adults report participating in vigorous-intensity activity by the number of minutes reported. To calculate minutes per week for the equivalent combination of moderate and vigorous-intensity activity, minutes per week of moderate-intensity activity are added to two times the minutes per week of vigorous-intensity activity.

    If responses meet the criteria for one activity (vigorous or moderate) but the status of the other activity is unknown, the record is included in the numerator and the denominator. If responses do not meet the criteria for one activity and the status of the other activity is unknown, the record is dropped from the analysis.

    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.
