About the National Data
Data source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 27.6 percent of adults aged 18 years and over performed muscle-strengthening activities on 2 or more days of the week in 2018
Target: 32.1 percent
For this indicator, adults were classified as doing strengthening activities if they responded that they did these activities 2 to 28 times per week.
Because Healthy People 2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
