Abstract 1 Title: Assessing the Social Determinants of Obesity in Latino Immigrants: Using Geographic Information Systems (GIS) from Start to Finish in a Study Design
Presentation Abstract 1: This presentation will showcase how Geographic Information Systems (GIS) technology was used throughout the lifecycle of an assessment of the social determinants of obesity in Latino immigrants. This population-based, cross-sectional pilot study sought to understand the relationship between obesity-related variables, the built environment, and the resulting impact on the target population in Albertville, Alabama.
In Phase I, investigators cartographically mapped the demographics of the study area and utilized a GIS tool developed by the Centers for Disease Control (CDC) to develop a random sampling strategy to ensure the recruitment of a representative sample of Latino and non-Latino study participants.
In Phase II, a variety of geospatial data was used to develop a "walkability" index of the study area. The correlation between the walkability of the built environment and the health survey data collected was then calculated. The final phase of the project involved the cartographic visualization of the study results.
Abstract 2 Title: Using Sankey Diagrams in Program Evaluation
Presentation Abstract 2: Sankey diagrams are data visualization tools that illustrate how quantities vary in dynamic processes. Key features are arrows that lead from one point in time to another and vary in width proportional to the quantities they represent. The diagrams are commonly used in engineering applications to track processes and resource flows across time. However, Sankey diagrams can also be used in program evaluation settings. They can: assist process evaluations by providing visual descriptions that illustrate how systems under study change across time; facilitate outcomes evaluation by enabling rapid, powerful comparisons between intervention and comparison groups; and aid in needs assessment by enabling the identification of critical time points or transitions in the system under evaluation. These applications will be demonstrated with Sankey diagrams from a longitudinal evaluation of treatments for children with autism, and for an evaluation of programs designed to improve retention and graduation rates among university students.
