Environmental Measures of Physical Activity Supports Perception Versus Reality
Karen A. Kirtland,Dwayne E. Porter,Cheryl L. Addy,Matthew J. Neet,Joel E. Williams,Patricia A. Sharpe,Patricia A. Sharpe,Linda J. Neff,C. Dexter Kimsey,Barbara E. Ainsworth +9 more
TL;DR: Though causality between perception of access and safety and actual physical activity level cannot be assumed, those meeting national physical activity guidelines or reporting some physical activity demonstrated greatest agreement with access to recreation facilities, while those not meeting the guidelines demonstrated greater agreement with safety of recreation facilities.
Journal ArticleDOI
Validation of 3 Food Outlet Databases: Completeness and Geospatial Accuracy in Rural and Urban Food Environments
Angela D. Liese,Natalie Colabianchi,Archana P. Lamichhane,Timothy L. Barnes,James Hibbert,Dwayne E. Porter,Michele Nichols,Andrew B. Lawson +7 more
TL;DR: It is suggested that the validity of common data sources used to characterize the food environment is limited and the marked undercount of food outlets and the geospatial inaccuracies observed have the potential to introduce bias into studies evaluating the impact of the built food environment.
Journal ArticleDOI
Twitter reveals human mobility dynamics during the COVID-19 pandemic.
TL;DR: It is found that the triggers of mobility changes correspond well with the national announcements of mitigation measures, proving that Twitter-based mobility implies the effectiveness of those measures.
Journal ArticleDOI
Using geographic information systems and regression analysis to evaluate relationships between land use and fecal coliform bacterial pollution
TL;DR: The results of the regression analyses indicate that proximity to areas with septic tanks, rainfall runoff from urbanized areas are important predictors of fecal coliform densities in the estuary, and ground saturation effects may be an important part of feces deposition in winter months.
Journal ArticleDOI

Angela D. Liese,Robin C. Puett,Archana P. Lamichhane,Michele Nichols,Dana Dabelea,Andrew B. Lawson,Dwayne E. Porter,James Hibbert,Ralph B. D'Agostino,Elizabeth J. Mayer-Davis +9 more
TL;DR: This study suggests that neighborhood characteristics related to greater affluence, occupation, and education are associated with higher type 1 diabetes risk.
