About the National Data
Data Source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 47.9 percent of adults aged 18 years and over engaged in aerobic physical activity of at least moderate intensity for at least 150 minutes/week, or at least 75 minutes/week of vigorous intensity, or an equivalent combination in 2020
Target: 52.9 percent
Percentage point improvement
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 54.2% in 2018 to 47.9% in 2020. The target was revised from 59.2% to 52.9% using the original target setting method.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
