Schools have an important role to play in obesity prevention, but little is known about the food environment in small, predominately rural schools. The primary purpose of this study was to compare the availability and student purchasing of foods sold outside of the reimbursable meals program through à la carte or vending (ie, competitive foods) in small (n=7) and large (n=6) Kansas high schools.
A cross-sectional observational study design was used to capture the number of à la carte and vending items available and purchased, and the fat and energy content of all available and purchased items on a single school day between January and May 2005.
Small schools had significantly fewer vending machines than large schools (median 3.0 [range 2.0 to 5.0] vs 6.5 [range 4.0 to 8.0], P<0.01]. Vending and à la carte items at small schools contained a median of 2.3 fewer fat grams per item (P≤0.05), whereas vending products contained a median of 25 kcal fewer per item (P≤0.05) than at large schools. Significantly less fat (median −15.4 g/student) and less energy (median −306.8 kcal/student) were purchased per student from all competitive food sources and from à la carte (median −12.9 g fat and −323.3 kcal/student) by students in small schools compared to students in large schools (P≤0.05).
The findings, which highlight less availability and lower energy content from competitive foods at small compared to large schools, have implications for understanding how small schools support their foodservice programs with limited dependence on competitive foods and the influence that food and nutrition professionals can have on school environments by providing more oversight into the nutritional quality of foods available.
