Presentations describing the LFLS guidelines were made to school administrators, faculty, and/or staff at the start of the 2004-2005 school year in intervention schools.
Chi-square analysis was used to determine differences in the proportion of a la carte and vending items that met LFLS nutrient guidelines and LFLS nutrient and portion guidelines at baseline between control and intervention schools.
0% of items met LFLS nutrient guidelines (ie, low fat and low sugar) and decreased to 22.
3% rows of beverage vending were allowable LFLS guideline beverages and decreased to 32.
05) between intervention and control schools was found in the proportion of a la carte, snack vending, and beverage vending items that met LFLS guidelines.
The LFLS guidelines implemented in this study were consistent with recommendations to establish nutrient and portion standards for foods and beverages sold in schools.
Across all schools, approximately 31% of items in a la carte and approximately 23% of snack vending items met LFLS nutrient guidelines, and approximately 42 % of beverage items were recommended.
In contrast, dramatic increases from baseline to follow-up in the proportion of items meeting LFLS nutrient guidelines were found in intervention schools.
Barriers to implement LFLS guidelines existed and resulted in not achieving complete elimination of high-fat, high-sugar, nonportioned foods and beverages.
These findings show that the LFLS guidelines implemented were stronger than the state of Maine's requirements at the time of the study that schools apply the 5% minimal nutritional value rule to all competitive foods sold during the school day.
