Clinical Trial
Journal Article
Advancing School and Community Engagement Now for Disease Prevention (ASCEND).
American Journal of Health Promotion : AJHP 2017 March
PURPOSE: To compare two intensity levels (standard vs. enhanced) of a nutrition and physical activity intervention vs. a control (usual programs) on nutrition knowledge, body mass index, fitness, academic performance, behavior, and medication use among elementary school students.
DESIGN: Quasi-experimental with three arms.
SETTING: Elementary schools, students' homes, and a supermarket.
SUBJECTS: A total of 1487 third-grade students.
INTERVENTION: The standard intervention (SI) provided daily physical activity in classrooms and a program on making healthful foods, using food labels. The enhanced intervention (EI) provided these plus additional components for students and their families.
MEASURES: Body mass index (zBMI), food label literacy, physical fitness, academic performance, behavior, and medication use for asthma or attention-deficit hyperactivity disorder (ADHD).
ANALYSIS: Multivariable generalized linear model and logistic regression to assess change in outcome measures.
RESULTS: Both the SI and EI groups gained less weight than the control (p < .001), but zBMI did not differ between groups (p = 1.00). There were no apparent effects on physical fitness or academic performance. Both intervention groups improved significantly but similarly in food label literacy (p = .36). Asthma medication use was reduced significantly in the SI group, and nonsignificantly (p = .10) in the EI group. Use of ADHD medication remained unchanged (p = .34).
CONCLUSION: The standard intervention may improve food label literacy and reduce asthma medication use in elementary school children, but an enhanced version provides no further benefit.
