About the National Data
Data Source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 25.2 percent of adults aged 18 years and over met the guidelines for aerobic physical activity and muscle-strengthening activity in 2020
Target: 29.7 percent
Percentage point improvement
Adults are classified as meeting the objective if they (1) participate in at least 150 minutes of moderate activity per week, 75 minutes of vigorous activity, or 150 minutes per week of an equivalent combination of activity and (2) report doing muscle strengthening activities and respond that they did these activities 2 to 28 times per week.
Total minutes per week of moderate-intensity activity are calculated by multiplying the times 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 times 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.
Note: Beginning with the NHIS re-design, "LIGHT" was dropped from the question, "How often do you do LIGHT OR MODERATE LEISURE-TIME physical activities…", in the rotating core starting in 2020 to be more consistent with the aerobic component of the physical activity guidelines.
In 2022, this objective was revised due to the 2019 NHIS redesign and 2020 survey question changes for aerobic physical activity. 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 24.0% in 2018 to 25.2% in 2020. The target was revised from 28.4% to 29.7% using the original target setting method.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
