TLDR
In this article, the authors employed three activity space measures to estimate food accessibility: route network buffer, time-weighted standard deviational ellipse (SDE), and mode-weight SDE.Abstract:
Spatial access to healthy foods has drawn growing attention regarding the relationship with people's health conditions and demographic and socioeconomic characteristics. Individuals' differences and the impact of travel behaviors on food accessibility, however, are rarely studied. This study incorporates mobility, time, and transportation mode components to measure each individual's access to healthy foods. We employed three activity space measures to estimate food accessibility: route network buffer, time-weighted standard deviational ellipse (SDE), and mode-weighted SDE. Food accessibility in three activity spaces shows similar variabilities. Geographic size and spatial access to healthy foods differ significantly by income and employment for all three activity space measures. People with higher incomes and those who are currently employed are likely to have larger activity spaces and higher food accessibility. As age increases, people tend to increase their size of activity spaces (in both SDE measures...read more

TL;DR: In this article, the authors developed a center to address state-of-the-art research, create innovating educational programs, and support technology transfers using commercially viable results to assist the Army Research Laboratory to develop the next generation Future Combat System in the telecommunications sector that assures prevention of perceived threats, and non-line of sight/Beyond line of sight lethal support.
Health research needs more comprehensive accessibility measures: integrating time and transport modes from open data
TL;DR: In this paper, the authors demonstrate the importance of using multimodal spatio-temporal accessibility measures when conducting research in urban contexts and propose a methodological approach for integrating different travel modes and temporality to spatial accessibility analyses.

TL;DR: It is confirmed that food behaviours are related to activity space-based food environment measures, which provide a more comprehensive accounting of food retail exposure than home-based measures.

Exploring relationships of grocery shopping patterns and healthy food accessibility in residential neighborhoods and activity space
Jingjing Li,Changjoo Kim +1 more
TL;DR: A deeper insight is provided into the relationships between grocery shopping patterns and healthy food accessibility by accounting for various spatial contextual units and improves nuanced understanding of the spatial heterogeneity in healthy food environment and its associations with shopping patterns between more urbanized areas and more rural areas depending on residential neighborhoods and activity space.

TL;DR: Results provide strong support for the view that differentiation does exist among the five areas and that the measures do relate to the phenomena with which they are identified.

TL;DR: In this article, the relationship between fruit and vegetable intake and the incidence of cardiovascular disease and cancer and of deaths from other causes in two prospective cohorts was evaluated, and the strongest inverse association with major chronic disease and cardiovascular disease was found for green leafy vegetables.
