About the National Data
Data
Data Source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 41.3 percent of adults aged 65 years and over with reduced physical or cognitive function engaged in light, moderate, or vigorous leisure-time physical activities in 2018
Target: 51.0 percent
Numerator
Number of adults aged 65 years and over with reduced physical or cognitive function who engage in light, moderate, or vigorous leisure-time physical activities.
Denominator
Number of adults aged 65 years and over with reduced physical or cognitive function.
Target-setting method
Projection
Target-setting method details
Linear trend fitted using weighted least squares and a projection at the 50 percent prediction interval.
Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using weighted least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 50 percent prediction interval was selected because no additional information could be used to assess the trend line, so the target was based on the projection.
Methodology
Methodology notes
Physical activity for those with reduced physical or cognitive function is defined as at least 10 minutes per week of any light, moderate, or vigorous activity.
History
Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
1. 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.
