Table 3 Correlations Between Adolescent Outcomes and Access to Fast food Restaurants, Convenience Stores, and Percent Open Space for Different Buffer Types at 1,600 Meters

From: Creating a replicable, valid cross-platform buffering technique: The sausage network buffer for measuring food and physical activity built environments

Environmental measure for correlation (across) Fast -food purchases Fruit and vegetable consumption Moderate and vigorous physical activity
Outcome measure for correlation (across) Fast-food restaurant counts Convenience storecounts Open Space%
