BRFSS Data Release Notes


General Release Notes

2019 BRFSS


The default report has been changed to the statewide estimate for the most recent three years of data. This change was implemented to better align with our other data sources. Users can still view all years of data and data by county by clicking on the Modify Query Definition, selecting all available years (Step 2: TIME PERIOD), setting the geography to county (Step 3: GEOGRAPHIC AREA), selecting geography as the display by (category) (Step 8), and clicking submit.

New BRFSS indicators added in 2019

There are many new indicators available:

Demographics

Health Behavior

Access to Health Care

Screening and Preventive Services

Chronic Diseases and Conditions


New BRFSS dimensions added in 2019

A new geographic dimension was added in 2019 to allow users to view reports by Primary Care Service Area.

There are also several new dimensions available to allow users to view reports by other health behaviors or conditions:

2018 BRFSS


Changes in the race/ethnicity dimensions.

In 2018, the Hawai'i Department of Health (DOH) revised how it collects race/ethnicity information in the Behavioral Risk Factor Surveillance System (BRFSS). The new methodology better aligns with national data collection standards and complies with the race/ethnicity algorithm used by the Office of Health Status Monitoring in DOH.

There are now two versions of DOH race/ethnicity: (2011+, new) and (2011-2017).
For a limited time, both versions of DOH race/ethnicity will be available, to give users an opportunity to compare and assess the impact of this change on indicators that are of interest to them. Please plan on transitioning to the new (2011+, new) race/ethnicity dimension going forward, as this is the new standard for DOH.

Poverty Level (2014+) dimension.

This new socioeconomic indicator dimension is based on multiple questions including the number of people living in the household and the annual household income from all sources. These numbers are compared to the annual US Department of Health and Human Services Poverty Guidelines to approximate the respondent's Federal Poverty Level percentage. This data is available from 2014 to the most recent year. Queries that request an indicator by this dimension will only include data from 2014 forward.

Sexual and Gender Minority (2014+) dimension.

This new demographic indicator dimension is based on sexual orientation and transgender identity. Adults who identify their sexual orientation as gay, lesbian, bisexual or something else, or who identify as transgender are coded as "yes" all others are coded as "no". This data is available from 2014 to the most recent year. Queries that request an indicator by this dimension will only include data from 2014 forward.

Transgender (2014+) dimension.

This new demographic indicator dimension is based on transgender identity. Adults who identify as transgender (male-to-female, female-to-male or gender non-conforming) are coded as "yes" all others are coded as "no". This data is available from 2014 to the most recent year. Queries that request an indicator by this dimension will only include data from 2014 forward.

2017 BRFSS


The underlying SAS code was modified to more accurately generate the asymmetric confidence intervals that occur when point prevalences approach 0 and 1. This code change will impact all BRFSS reports. As a result, there may be slight differences in confidence intervals and relative standard errors, and hence, reportability, from previous years. Please check your query results carefully and re-run reports as necessary. HI-IBIS runs on SAS version 9.4 (SAS Institute Inc: Cary, NC).


All Years


Race/Ethnicity Data

Respondents are asked the following question to ascertain their race/ethnicity:
This question is used to create the Race/ Ethnicity classifications. In HHDW, the most granular level is the program race/ethnicity (PRG) which rolls up into the DOH standard race/ethnicity (DOH), which rolls up into Census race reporting categories (Census). The table below illustrates how the data is aggregated.

Other Information

Note about indicator/dimension titles:

The BRFSS is constantly changing. HHDW staff carefully review the BRFSS survey instrument each year to assess how changes in the survey instrument impact indicators and dimensions within the HI-IBIS system. When an indicator or dimension is not available across all years in HI-IBIS, this information will be added to the name. For example, there are two versions of Adults with at least one disability (2016+) and (2013-2016). In 2016, a question about auditory disability was added to the BRFSS so a new indicator was created to capture any disability including hearing issues--Adults with at least one disability (2016+). Poverty level (2014+) is available from 2014 forward only based on when questions about household members for cell phone respondents were added to the survey. A query with data by Poverty level (2014+) dimension will only contain data from 2014+ regardless of the years of data for the base indicator. If you have questions, check the Question Wording in the Data Notes section of the report.
