Reduce the proportion of adults who do no physical activity in their free time — PA‑01 Data Methodology and Measurement

About the National Data


Baseline: 26.1 percent of adults aged 18 years and over engaged in no leisure-time physical activity in 2020

Target: 21.8 percent

Number of adults aged 18 years and over who report that they never do, or are unable to do, moderate physical activity and that they never do, or are unable to do, vigorous physical activity.
Number of adults aged 18 years and over.
Target-setting method
Percentage point improvement
Target-setting method details
Percentage point improvement from the baseline using Cohen's h effect size of 0.10.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the trend was not expected to continue. A percentage point improvement was calculated using Cohen's h effect size of 0.1. This method was used because it was a statistically significant improvement from the baseline and the Healthy People 2030 Workgroup Subject Matter Experts expected the data to move in the desired direction during the next decade.


Methodology notes

Adults are classified as not engaging in leisure time physical activity if they answer "never" or "unable to do this type of activity" to both the vigorous and moderate physical activity questions. Responses of "over 28 times per week" to either vigorous or moderate or both sets of questions were eliminated from the denominator.


Comparable HP2020 objective
Modified, which includes core objectives that are continuing from HP2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective PA-1 in that objective PA-01 was changed to reflect 2018 Physical Activity guidelines and due to 2019 National Health Interview Survey (NHIS) redesign. The 10-minute physical activity requirement and light intensity physical activity were dropped from the NHIS questionnaire.
Revision History

In 2022, this objective was revised due to the 2019 NHIS redesign and 2020 survey question changes. The baseline questions changed from, "How often do you do VIGOROUS leisure-time physical activities for AT LEAST 10 MINUTES that cause HEAVY sweating or LARGE increases in breathing or heart rate?" and "How often do you do LIGHT OR MODERATE LEISURE-TIME physical activities for AT LEAST 10 MINUTES that cause ONLY LIGHT sweating or a SLIGHT to MODERATE increase in breathing or heart rate?" to "How often do you do MODERATE-INTENSITY LEISURE-TIME physical activities?" and "How often do you do VIGOROUS-INTENSITY LEISURE-TIME physical activities?"
The baseline was revised from 25.4% in 2018 to 26.1% in 2020. The target was revised from 21.2% to 21.8% using the original target setting method.

1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
