Healthy eating guidelines for a school jurisdiction: collaborative design and implementation

Area of Science:

• Public Health
• Nutrition Science
• Educational Policy

Background:

• Healthy eating is crucial for optimal child development.
• Schools offer a prime environment for influencing student dietary habits.
• The Healthy Eating Guidelines Initiative (HEGI) was a collaborative effort to establish healthy eating standards within a school system.

Purpose of the Study:

• To evaluate the impact of the HEGI on the school food environment.
• To assess changes in students' self-reported dietary behaviors following HEGI implementation.

Main Methods:

• A quasi-experimental design was employed across a school jurisdiction.
• Data were collected using school environment assessments and student questionnaires pre- and post-initiative.
• Schools of all grade levels (elementary, middle, high) were invited to participate.

Main Results:

• Twenty-two schools participated, with successful guideline implementation in 17.
• A higher percentage of students reported healthier eating habits post-HEGI.
• Significant improvements in dietary behaviors were observed in students at schools with cafeteria-style food services, but not in those with limited or no food service.

Conclusions:

• School-wide healthy eating guidelines can positively influence the school food environment and student nutrition.
• The HEGI demonstrates potential as an effective strategy for promoting healthy eating among students.
• The presence of on-site food service appears to be a key factor in the success of such initiatives.
