Acquisition costs for materials and time and wage data for employees involved in implementing the program were used to estimate fixed and variable costs. Cost-effectiveness was determined using the ratio of variable costs to program efficacy outcomes.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nThe costs of implementing the program over 5 weeks were $5433.26 per school in fixed costs and $2.11 per student in variable costs, equaling a total cost of $8637.17 per school, or $0.23 per student per day. This investment yielded significant increases in the proportion of students served fruit and lunch and a significant decrease in the proportion of students buying snacks. The cost-effectiveness of the program, per student over 5 weeks, was $1.20 per additional fruit served during meals, $8.43 per additional full-priced lunch served, $2.11 per additional reduced-price\/free lunch served, and $1.69 per reduction in snacks sold.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nSNaX demonstrated the feasibility and cost-effectiveness of a middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. Its cost is modest and unlikely to be a significant barrier to adoption for many schools considering its implementation.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-24388","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Medicine, New York University School of Medicine, New York, NY; Department of Population Health, New York University School of Medicine, New York, NY.
