Washington Environmental Health Disparities Map Reveals Racial and Income Environmental Injustice

Working our partners, we recently published analyses based on our Washington Environmental Health Disparities (WA EHD) Map.


There are a couple notable figures that reveal the relationships between race/ethnicity, income and cumulative environmental health risk in the state of Washington.



This first one shows that census tracts with a greater proportion of residents who are people of color tend to have higher environmental health disparity ranks — they’re more impacted by cumulative environmental health risks.




This second one shows that census tracts with higher income “ranking” — in other words have lower median incomes, tend to have higher environmental health disparity rankings.  Thus, lower income census tracts tend to be more impacted by cumulative environmental health risks.

New National Institute on Aging Grant to Use Wearable Sensors for Early Diagnosis of Dementia

Our group is collaborating with the other researchers at the UW, Seattle VA Hospital, Cleveland Clinic, and the Mayo Clinic on a new study — Technology for Early Diagnosis of Dementia (TEDD) — to use sensor technologies to improve early diagnosis of Alzheimers Disease and Dementia with Lewy Bodies.  Early discimination of individuals on the trajectory to these two different diseases may lead more appropriate treatments to improve outcomes.

This work leverages our group’s previous work with wearable motion and physiologic sensors. In the current study we will be collaborating with experts in sleep monitoring and cognitive assessments.

The Principal Investigator, Dr. Debby Tsuang will lead this study funded by the NIH National Institutes of Aging.

The study will recruit participants from sites in different locations in the US, who have either Alzhiemer’s Disease or Dementia with Lewy Bodies, who will use a variety of sensors which will provide potential valuable data useful in disciminating the mobility, sleep, and other quality of life indicators of older adults who have these diseases. In a later phase of the study, we will use this information to examine a larger cohort of adults with mild cognitive impairment, and track the assocations between their cognitive decline over time and various sensor data.
