Health and Place

  1. 1. Place and Health<br />1<br />
  2. 2. Why We Care<br />The built environment impacts health by impacting:<br />Access & Exposure<br />2<br />
  3. 3. Access<br />3<br />
  4. 4. Exposure<br />4<br />
  5. 5. Active Living Research<br />Established in 2001, ALR supports research to identify environmental factors and policies that influence physical activity.<br />Administered by San Diego State University Research Foundation.<br />Led by Dr. James Sallis<br />5<br />
  6. 6. Genes & Environment Initiative<br />The Genes and Environment Initiative is a five-year, NIH-wide effort to identify the genetic and environmental basis of asthma, diabetes, cancer, and other common illnesses<br />SENSORS<br />SYSTEMS<br />ANALYTICS<br />6<br />
  7. 7. Physical<br />Activity<br />Location<br />Measurement<br />System<br />7<br />
  8. 8. The PALMS Story<br />PALMS SYSTEM<br />ANA<br />L<br />Y<br />S<br />I<br />S<br />GIS<br />LOCATION<br />Data Processing<br />Merging & Calculations<br />INDIVIDUALS<br />BEHAVIOR<br />SENSING<br />TECHNOLOGY<br />STATISTICS<br />User Interface<br />TIME<br />Web-based<br />ENVIRONMENT<br />EXPOSURE<br />System Architecture<br />VIZUALIZE<br />Security & Sharing<br />Add Data Sources<br />Collaborate<br />Study Creation<br />Re-analyze<br />Researcher Points of Entry<br />8<br />
  9. 9. Sensors for Physical Activity, Location & Exposure<br />Physical activity<br />M – Actigraph<br />M – Actical<br />HR+M - Actiheart<br />HR+M – Actitrainer<br />HR+M+ respiration + skin temp – Bioharness<br />Location - GPS<br />DG-100<br />BT-335<br />Qstarz 1000<br />9<br />
  10. 10. Accelerometers and heart rate monitors tell how active and when…<br />10<br />
  11. 11. When combined with GPS, we also know where activity occurs<br />Heart rate<br />shown in<br />Google Earth<br /> resting lightmoderatevigorous<br />11<br />
  12. 12. When combined with GIS, we know the context in which activity occurs<br />Heart rate<br />shown in<br />ESRI ArcGIS<br />against land use<br />12<br />
  13. 13. PALMS GPS Data Cleaning<br />Before – Multi-story buildings generate noise<br />After – Noise removedYellow = walking Orange = pausedGray circles = relative time at location<br />13<br />

  16. 16. PALMS is being designed for Data Sharing<br />“… making data as widely and freely available as possible, while safeguarding the privacy of participants, and protecting confidential and proprietary data.” – NIH1<br />—Data related to your own specialty—Rare data<br />— Clinical population data —Pooled data<br />— Data promoting education —Test/training data <br />— Calculations & visualizations —Protocols<br />1http://grants.nih.gov/grants/policy/data_sharing/data_sharing_guidance.htm <br />16<br />
  17. 17. Our Questions<br />Large Data Sets<br />Population vs. Individuals<br />Time Dependence<br />Visualizations<br />Pattern Recognition<br />17<br />
