Increase the proportion of low-income youth who have a preventive dental visit — OH‑09 Data Methodology and Measurement

About the National Data


Baseline: 75.8 percent of children aged 1 through 17 years who reside in households with income less than 200 percent of the federal poverty level received a preventive dental service in 2016-17

Target: 79.9 percent

Number of low-income and poor youth aged 1 through 17 years who had 1 or more preventive dental visits (such as check-ups, dental cleanings, dental sealants, or fluoride treatments) in the past year.
Number of low-income and poor youth, aged 1 through 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 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.


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 OH-8 in that objective OH-8 used data from the Medical Expenditure Panel Survey (MEPS) to track preventive dental services among low-income youth aged 2 to 18 years, while this objective uses data from the National Survey of Children's Health (NSCH) to track preventive dental visits among low-income youth aged 1 to 17 years.
Revision History

In 2021, the baseline was revised to correct a programming error. The baseline estimate was revised from 78.8 percent to 75.8 percent in 2016-2017. The target was adjusted from 82.7 percent to 79.9 percent to reflect the revised baseline using the original (Method II) percentage point improvement target-setting method.

Trend issues
Due to significant changes in the mode of data collection and sampling frame, 2016 NSCH data cannot be compared to prior NSCH data. This redesign for the NSCH will support trend analyses beginning with data from 2016. The wording of the survey items capturing preventive dental care changed to include care provided by other oral health care providers in addition to dentists.

1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
