About the National Data
Data
Baseline: 9.0 percent of adolescents aged 12 to 17 years reported alcohol use in the past 30 days in 2018
Target: 6.3 percent
Numerator
Number of adolescents aged 12 to 17 years who reported using any alcohol during the past 30 days.
Denominator
Number of adolescents aged 12 to 17 years.
Target-setting method
Percentage point improvement
Target-setting method details
Percentage point improvement from the baseline using Cohen's h effect size of 0.10.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because Healthy People 2030 Workgroup Subject Matter Experts (SMEs) expected a slowdown in decline (i.e., nonlinear trend) even though prevention and intervention efforts continue. 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 SMEs viewed this as an ambitious yet achievable target.
Methodology
Methodology notes
Alcohol use by adolescents aged 12 to 17 years is defined as using alcohol in the past month. The answers for each of the substances are examined for each respondent. Persons are considered to have used alcohol if they report any use in the past 30 days.
History
Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective SA-13.1 in that objective SA-13.1 tracked adolescent-reported use of alcohol or illicit drugs during the past 30 days, while this objective tracks adolescent-reported use of alcohol during the past 30 days.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
