Abstract
Background
There are currently no national standards for lunch period lengths or physical activity
in schools. Research is needed to better understand the impact of school initiatives
that improve policies related to lunch and movement opportunities on student outcomes.
Additionally, best practices are necessary to support schools that are considering
initiatives that address these factors.
Objective
This study examined the impact of implementing longer lunch periods, recess, and other
movement opportunities on student outcomes and best practices for implementation.
Design
A mixed-methods study including surveys and semistructured interviews and focus groups
conducted during the 2019-2020 school year.
Participants/setting
Surveys (n = 5107) from students in grades 3 and 4 attending 19 pilot and 11 matched
control elementary schools and interviews/focus groups among principals, cafeteria
managers, teachers, and parents in a representative subsample (n = 6) of pilot schools
in Anchorage Alaska.
Main outcome measures
Students’ self-reported hunger levels and mood and perceptions and supportive strategies
from school principals, cafeteria staff, teachers, and parents were examined.
Statistical analyses performed
Mixed-model analysis of variance accounting for student demographics with students
as a random effect (students nested within schools) were used to examine differences
in hunger and mood. For interviews/focus groups, responses were analyzed qualitatively
using principles of content analysis.
Results
Longer lunch periods were associated with significantly reduced hunger at the end
of lunch period and significantly increased self-reported happiness in the cafeteria.
Based on interviews/focus groups with school staff and parents, the initiative was
generally perceived positively with reported benefits including reductions in disciplinary
issues and improvements in student focus, social and emotional learning, and overall
student happiness and well-being. Several supportive strategies were identified.
Conclusions
Initiatives that increase lunch period lengths and physical activity opportunities
have the potential to reduce students’ hunger levels and improve focus and behaviors
in the classroom. Schools should consider similar initiatives that incorporate the
suggested strategies to potentially improve outcomes among students.
