Purchasing Behavior, Setting, Pricing, Family: Determinants of School Lunch Participation

Area of Science:

• Nutrition Science
• Public Health
• Pediatrics

Background:

• School lunch programs are expanding in Germany, yet student participation remains low.
• Students often opt for less healthy food choices when school lunches are not utilized.

Purpose of the Study:

• To identify predictors of school lunch participation among schoolchildren.
• To understand the reasons behind nonparticipation in school lunch programs.

Main Methods:

• A study involving 1215 schoolchildren in Germany.
• Data collection included child meal habits, parent-reported family information (including socioeconomic status), and on-site anthropometry.
• Logistic regression analysis was used to assess associations, controlling for relevant variables and including school as a random effect.

Main Results:

• Family factors significantly predicted school lunch participation.
• Positive association found between eating breakfast on schooldays and school lunch participation (ORadj = 2.20).
• Negative associations observed for lower secondary schools (ORadj = 0.52) and low socioeconomic status (SES) (ORadj = 0.25).
• Key reasons for nonparticipation included taste, time constraints, and cost, with parents emphasizing pricing and taste.
• Non-participants consumed more sandwiches and energy drinks; participants showed a lower prevalence of overweight (OR = 0.66).

Conclusions:

• School lunch participation is strongly influenced by family-related factors.
• Addressing school and lunch-specific factors like taste, pricing, and timing is crucial for increasing utilization.
• Promoting school lunch participation may contribute to better weight management among students.
