Precision Surveillance of Hypertension, Obesity and Diabetes for Healthy Aging

The Precision SHODHA project aims to provide state and local governments with actionable small areal insights on hypertension, obesity and diabetes care in USA and India. The proposed project involves harmonizing datasets from national surveys and administrative sources, use small-area estimation techniques and decision sciences frameworks.

This is ongoing work with Dr. Mohammed K. Ali and Dr. Nikhil Tandon.

We collaborate with Emory’s Department of Biostatistics (Dr. Emily Peterson) and Georgia Tech’s School of Industrial and Systems Engineering (Dr. Gian Gabriel Garcia).

Erica Kocher is working with a team from Georgia Tech to understand state-level cost effectiveness in achievement of WHO Diabetes Compact targets in India.

Jiali Guo is using electronic health records from USA to develop care continua.

Thomas Hsiao is working with some cool kiosk data to develop county estimates of hypertension and overweight/obesity prevalence for USA.

  2. Cost effectiveness of intervening on different steps of disease care continuum
  3. Prevalence of cardiometabolic disease subphenotypes
  4. Population achievement of personalized targets for glycemic and blood pressure control in India
  5. Care continuum among youth-onset diabetes in India
  6. Data visualization tools for continuum of care in India and USA
  7. Data fusion of real-world data, surveys and kiosk data for spatial statistics
