title: Where do food desert residents buy most of their junk food? Supermarkets.
abstract: OBJECTIVE
  To examine where residents in an area with limited access to healthy foods (an urban food desert) purchased healthier and less healthy foods.
  
  
  METHODS
  Food shopping receipts were collected over a one-week period in 2013. These were analysed to describe where residents shopped for food and what types of food they bought.
  
  
  METHODS
  Two low-income, predominantly African-American neighbourhoods with limited access to healthy foods in Pittsburgh, PA, USA.
  
  
  METHODS
  Two hundred and ninety-three households in which the primary food shoppers were predominantly female (77·8 %) and non-Hispanic black (91·1 %) adults.
  
  
  RESULTS
  Full-service supermarkets were by far the most common food retail outlet from which food receipts were returned and accounted for a much larger proportion (57·4 %) of food and beverage expenditures, both healthy and unhealthy, than other food retail outlets. Although patronized less frequently, convenience stores were notable purveyors of unhealthy foods.
  
  
  CONCLUSIONS
  Findings highlight the need to implement policies that can help to decrease unhealthy food purchases in full-service supermarkets and convenience stores and increase healthy food purchases in convenience stores.
