N2 - INTRODUCTION Obese or overweight children have an increased risk for chronic diseases. Targeting diet and exercise in schools could help prevent childhood obesity. We have previously shown the effectiveness of a 90-minute nutrition program in improving elementary school students' food-label literacy. The objective of this study was to investigate the effectiveness of a 45-minute version of the program. METHODS We conducted a pre-post study in a public school district, with no control group. We provided teacher training and program materials. Participants were 5th-grade students in 5 schools who had parental consent and were willing to take part. We condensed the program to a 45-minute lesson with a presentation and hands-on activity. The lesson showed students why and how to make healthful food choices based on Nutrition Facts panels and ingredient lists. The district's physical education teachers taught the lesson. The primary outcome measure was food-label literacy (ie, the ability to distinguish between more and less healthful foods using a validated test instrument with Nutrition Facts panels and ingredient lists). RESULTS A total of 212 students completed pre-post measures. Following program delivery, we observed a significant gain of 16.2 percentage points in scores overall, ranging from 4.3 percentage points to 23.6 percentage points among schools. Results were similar to those achieved with the 90-minute program. DISCUSSION The condensed nutrition program improved students' food-label literacy while requiring a minimal allocation of time. Further studies in other school districts would be useful. SN - 1545-1151 UR - http://dx.doi.org/10.5888/pcd11.130161 DO - 10.5888/pcd11.130161 ER -
