title: If we offer it, will children buy it? Sales of healthy foods mirrored their availability in a community sport, commercial setting in Alberta, Canada.
abstract: BACKGROUND
  Community sports settings are often sources of unhealthy foods for children. Many managers in these settings are reluctant to increase availability of healthy food options because they perceive that healthy foods are not profitable. This study assessed the independent contribution of increased availability of healthy foods to their sales in a community sport, commercial context. Change in revenues per patron was also examined.
  
  
  METHODS
  The availability of healthy items was increased from 9.1% at baseline (35 days) to 25.0% during the intervention period (40 days), returning to 9.1% postintervention (6 days). Purchases of all patrons who bought foods/beverages (n=17,262 items sold) from two concessions at an outdoor community pool were assessed from baseline to postintervention. Chi-square analyses assessed differences in the proportion of healthy and unhealthy items sold, as well as in the proportion of total revenues per patron across periods. A trained observer also recorded qualitative observations pertaining to a subset of patrons' (n=221) dietary behaviors and activities.
  
  
  RESULTS
  Healthy items represented 7.7%, 22.7%, and 9.8% of sales during the preintervention, intervention, and postintervention periods, respectively (p<0.01). Sales of healthy beverages exceeded sales of all other product types. The proportion of total revenues per patron did not differ by period.
  
  
  CONCLUSIONS
  Food availability was an important environmental determinant of food purchasing behaviors in this community commercial context, given that sales of healthy foods closely mirrored their availability. Increased availability of healthy foods in community and commercial settings is important because concurrent changes within multiple environments will be required to improve children's dietary behaviors.
