Purpose:
Examine the reach, efficacy, adoption, implementation, and maintenance of a physical activity and nutrition curriculum for middle-school students.
Design:
Nonexperimental pilot evaluation of a statewide dissemination trial.
Setting:
California middle schools during the 2006 to 2007 school year.
Subjects:
Sixteen classes (N = 668 students and 16 teachers) sampled from the statewide pool who used the program.
Intervention:
An eight-lesson nutrition and physical activity curriculum, "Exercise Your Options" (EYO), including a teacher guide, video clips, a student activity booklet, and ancillary materials was made available to teachers.
Measures:
Program records, classroom observations, teacher surveys, and student presurveys and postsurveys (assessing physical activity, sedentary behaviors, and dietary intake).
Analysis:
Descriptive statistics and multilevel random-coefficient modeling.
Results:
The EYO program reached 234,442 middle-school students in California. During the program, total physical activity increased (p < .001), whereas watching TV/DVDs and playing electronic games/computer use decreased (p < .05). Intake of dairy products increased (p < .05), whereas consumption of sugars/sweets decreased (p < .001). Forty-two percent of eligible middle-school classrooms ordered the program materials. Eighty-six percent of sampled teachers implemented all of the lessons. Over the past 5 years, 51% of all middle-school students in California were exposed to the program.
Conclusions:
The EYO program showed its potential for moderate to high public health impact among California middle-school students.
