Fig. 4: The association between income, educational attainment, grocery store and fast food access, with food consumption and BMI status.
From: Large-scale diet tracking data reveal disparate associations between food environment and diet
Independent contributions of high income (median family income higher than or equal to $70,241), high educational attainment (fraction of population with college education 29.8% or higher), high grocery store access (fraction of population that is closer than 0.5 miles from nearest grocery store is greater than or equal to than 20.3%), and low fast food access (less than or equal to 5.0% of all businesses are fast-food chains) on relative difference in consumption of a fresh fruits and vegetables, b fast food, c soda, and d relative difference in fraction affected by overweight or obesity (BMI > 25). Cut points correspond to median values. Y-axes are oriented such that consistently higher is better. Estimates are based on matching experiments controlling for all but one treatment variable, across N = 4911 matched pairs of zip codes (Methods). Bar height corresponds to mean values; error bars correspond to 95% bootstrap confidence intervals (Methods). While the most highly predictive factors vary across outcomes, only high educational attainment was associated with a sizeable difference of 13.1% in the fraction affected by overweight or obesity.
