Vitalnet Age-Adjusted BRFSS Percents
To compare risk or prevalence between populations with different age structures,
it is generally recommended to adjust for age
are used to
compare death rates
When possible, Healthy People 2010 and 2020 Objectives with BRFSS data
Without age-adjustment, analyses can be misleading or incorrect.
Here is a real-world example:
- Percent Yes (Not Age-Adjusted) (Not AA)
- Percent Yes (Is Age-Adjusted) (Is AA)
Summary table showing the differences:
|Ever had diabetes (excluding pregnancy)?
||Weighted % Yes
If age-adjusted, Hispanic (11.4%) - White (6.4%) = 5.0%
If not age-adjusted, Hispanic (8.0%) - White (7.1%) = 0.9%
We have added age-adjusted percents to
Vitalnet Table and Map Maker
This lets you quickly and reliably do BRFSS age-adjusted analyses, with:
- No programming knowledge required.
- Assurance of correct, fully documented results.
- Publication-ready results produced in about a minute.
By comparing with (the few) existing age-adjusted analyses from other sources,
we verified Vitalnet is producing correct BRFSS age-adjusted percents.
We plan to add confidence intervals (using Jackknife replication) to the BRFSS age-adjusted percents,
within the next few months.
We use distribution #10 from
Klein and Schoenborn (2001)
Other standards can be built in as you specify.
