Can the provision of breakfast benefit school performance?

Area of Science:

• Nutrition and Public Health
• Educational Psychology
• Developmental Economics

Background:

• Nutritional status is linked to school performance indicators like attendance and achievement.
• Hunger and poor diet correlate with lower academic success, even after controlling for socioeconomic factors.
• Existing research on school meals often has methodological limitations.

Purpose of the Study:

• To evaluate the evidence on the impact of school meals on student performance.
• To identify gaps in the current research, particularly regarding long-term effects and study designs.
• To highlight the need for rigorous, long-term studies in resource-poor settings.

Main Methods:

• Review of existing studies examining associations between nutritional status and school performance.
• Evaluation of evidence from short-term and long-term studies on school meal programs, including breakfast programs.
• Analysis of study designs, including randomized controlled trials, quasi-experimental designs, and observational studies.

Main Results:

• Short-term studies indicate negative cognitive effects from missing breakfast and benefits from provision, especially in malnourished children.
• Studies on school meals, predominantly breakfast, suggest positive impacts on attendance and academic performance.
• Many studies suffer from design flaws, short durations, and lack of focus on the poorest countries, limiting generalizability.

Conclusions:

• While evidence suggests school meals benefit student performance, many studies are limited by design and duration.
• There is a critical need for long-term, randomized controlled trials of school meal programs in low-income countries.
• Future research should consider factors like child's age, nutritional status, school quality, meal timing, and the needs of vulnerable groups like orphans.
