Health Indicator Report of Utah Health Improvement Index (HII)

The HII is not a measure of health per se, but instead measures a combination of social and economic conditions that determine health. The HII ranges from 72 to 160 and has five groups: very high, high, average, low, and very low. Higher HII groups denote a greater need to improve these conditions, thereby also an opportunity to improve health. When combined with health indicators, the HII can identify differences in health that are linked to social and economic disadvantage, in other words, health disparities. Thus, it may be used as a guide to determine the type of intervention to implement in order to advance health equity and reduce, in an efficient and effective way, the burden of health disparities in our state.

Notes

The Utah Health Improvement Index (HII) is not a measure of health per se, but instead measures a combination of social and economic conditions that determine health. The HII ranges from 72 to 160 and has five groups: very high, high, average, low, and very low. Higher HII groups denote a greater need to improve these conditions, thereby also an opportunity to improve health.

Data Sources

  • Utah Data: Behavioral Risk Factor Surveillance System, Office of Public Health Assessment, Utah Department of Health
  • Population estimates produced by the UDOH Center for Health Data and Informatics. Linear interpolation of U.S. Census Bureau and ESRI ZIP Code data provided annual population estimates for ZIP Code areas by sex and age groups, IBIS Version 2018

Data Interpretation Issues

Consider the following limitations: # The Behavioral Risk Factor Surveillance System (BRFSS) is the primary source for indicators used to calculate the HII. The BRFSS is a telephone survey (with interviews using both landline and cell phones) that includes only adults 18 and older. # The HII is tied to Utah Small Areas, which were defined based on ZIP codes, local health districts, county boundaries, and input from local community representatives. These defined areas may not match local jurisdiction, community practices, etc. or capture all root causes driving health disparities. # Some small areas may have a high HII category because of their high and transient college student population. # Within the "average" and "low" HII areas, there may be small clusters of underserved communities, such as American Indian Tribes, racial/ethnic minorities or other minority groups. # The HII is not a measure of health per se, but instead measures a combination of social and economic conditions that determine health. In order to identify health disparities it must be combined with health indicators like the infant mortality rate. # The HII would be best used in connection with qualitative data to ensure the context in which communities experience health disparities is accurately understood.

Definition

A composite measure of the social determinants of health by geographic area, grounded in methods used by Gopal K. Singh for the Area Deprivation Index (ADI).

How Are We Doing?

According to 2015-2017 data, more than one-third (33%) of the 99 Small Areas have a high or very high HII: *Very Low HII: 20 Small Areas *Low HII: 25 Small Areas *Average HII: 18 Small Areas *High HII: 20 Small Areas *Very High HII: 16 Small Areas [[br]] Additionally, out of the 99 Small Areas, 73 are classified as urban and 26 as rural/frontier: * Very Low HII: 20 Small Areas (18 Urban and 2 Rural/Frontier) * Low HII: 25 Small Areas (19 Urban and 6 Rural/Frontier) * Average HII: 18 Small Areas (13 Urban and 5 Rural/Frontier) * High HII: 20 Small Areas (12 Urban and 8 Rural/Frontier) * Very High HII: 16 Small Areas (11 Urban and 5 Rural/Frontier)

What Is Being Done?

The Utah Department of Health is using the HII to inform work to address health disparities and advance health equity. * The UDOH Office of Health Disparities has used the HII to produce the report [http://health.utah.gov/disparities/data/ohd/HealthDisparitiesbyUtahStateLegislativeDistrict2019.pdf Health Disparities by Utah State Legislative District]. * The UDOH Bureau of Health Promotion is using the HII to understand and address health disparities in chronic disease. * The UDOH Bureau of Epidemiology is using the HII to understand and address health disparities in infectious disease. * The UDOH Office of Primary Care and Rural Health has created [https://ruralhealth.health.utah.gov/portal/ interactive maps with the HII].

Health Program Information

The UDOH Office of Health Disparities' (OHD) vision is for all people to have a fair opportunity at reaching their highest health potential given that health is crucial for well-being, longevity, and economic and social mobility. The OHD's mission is to advance health equity and reduce health disparities in Utah. Contact {{style color:#003366 disparities@utah.gov}} for more information.
