Target-setting method justification
Trend data were not available for this objective. 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.

History

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 the related Healthy People 2020 objectives in that objectives PA-8.2.1 used data from the National Health and Nutrition Examination Survey (NHANES) to track children aged 2 to 5 years who viewed television, videos, and/or played video games for no more than 2 hours a day, and objective PA-8.3.1 used data from NHANES to track children aged 2 to 5 years who used a computer or played computer games for no more than 2 hours a day. This objective uses data from the National Survey of Children's Health (NSCH) to track children aged 2 to 5 years whose total screen time is no more than 1 hour per day.
