The goals of this intervention study are to implement best practice strategies to expand and
promote the school breakfast program and test the impact upon student participation rates
among a) all 10th and 11th grade students and among a randomly selected cohort of 800
students b) total diet and body mass index and percent body fat inin 16 rural Minnesota
School-wide Primary Aim: Improve participation in the school breakfast program among high
school students. Hypothesis: School-wide school breakfast program participation will be
higher in the intervention versus comparison group.
We will accomplish the following secondary aims using a random subsample of 800 incoming 10th
and11th grade students.
Student-level Secondary Aims Secondary Aim 1: High school students in the intervention
condition will decrease their rate of weight gain relative to height gain as measured by
change in body mass index and percent body fat compared to students in the control condition.
Hypothesis: Body mass index and percent body fat will be maintained or reduced in the
treatment versus control group.
Secondary Aim 2: High school students in the intervention condition will maintain or decrease
their energy intake while improving dietary intakes of low fat dairy, whole grains and fresh
fruits compared to the control students.
Hypothesis: Energy intake (measured by 3, 24-hour recalls) will be maintained or reduced and
intakes of low fat dairy, whole grains and fresh fruits will increase more in the
Secondary Aim 3: Compared to students in the control condition, high school students in the
intervention condition will report receiving more support to eat school breakfast. Support
will be social (increased peer and school support) or related to the school environment
(satisfaction with serving locations and times, eating locations, foods and increased
availability of low fat dairy, fruits and whole grains for breakfast).
Hypothesis: The treatment group will report receiving more social and school environment
support for eating school breakfast than the comparison group (measured by a student survey).
