A low-cost, grab-and-go breakfast intervention for rural high school students: changes in school breakfast program participation among at-risk students in Minnesota

Objective: Evaluate the impact of a grab-and-go component embedded within a larger intervention designed to promote School Breakfast Program (SBP) participation. Design: Secondary data analysis. Setting: Rural Minnesota high schools. Participants: Eight schools were enrolled in the grab-and-go only intervention component. An at-risk sample of students (n = 364) who reported eating breakfast ≤3 d/wk at baseline was enrolled at these schools. Interventions: Grab-and-go style breakfast carts and policies were introduced to allow all students to eat outside the cafeteria. Main Outcome Measures: Administrative records were used to determine percent SBP participation (proportion of non-absent days on which fully reimbursable meals were received) for each student and school-level averages. Analysis: Linear mixed models. Results: School-level increases in SBP participation from baseline to the school year of intervention implementation were observed for schools enrolled in the grab-and-go only component (13.0% to 22.6%). Student-level increases in SBP participation were observed among the at-risk sample (7.6% to 21.9%) and among subgroups defined by free- or reduced-price meal eligibility and ethnic or racial background. Participation in SBP increased among students eligible for free or reduced-price meals from 13.9% to 30.7% and among ineligible students from 4.3% to 17.2%. Conclusions and Implications: Increasing access to the SBP and social support for eating breakfast are effective promotion strategies.
