Impact of school meals on educational outcomes in Addis Ababa, Ethiopia

OBJECTIVE: This study evaluated the impact of the Addis Ababa School Feeding Program (SFP) on educational outcomes. DESIGN: Single-group repeated measurement/longitudinal study design and multistage stratified sampling design were followed. Effect sizes estimates, repeated measures ANOVA, Chi-square, Generalised Additive Mixed Model and mixed effects negative binomial regression were used. Academic scores, attendance and dropout and height and weight of schoolchildren were collected. SETTING: School Feeding Programs in Addis Ababa, Ethiopia. PARTICIPANTS: Schoolchildren in primary schools and school directors and teachers in fifteen randomly selected schools for Key Informant Interview (KII). RESULTS: Anthropometric measurements of 4500 schoolchildren were taken from 50 schools. Academic scores of 3924 schoolchildren from 46 schools, class attendance records of 1584 schoolchildren from 18 schools and annual enrolment records of 50 schools were gathered. School meals achieved a minimum to large scale effects on educational outcomes with effect sizes (η (2)) of academic scores (boys = 0·023, girls = 0·04), enrolment (girls = 0·001, boys = 0·05) and attendance (Cramer’s V = 0·2). The average scores of girls were significantly higher than that of boys (P < 0·0001). Height-for-age in all schoolchildren (P < 0·01) and BMI-for-age Z-scores in adolescent girls of 15–19 years (P < 0·0001) never had a significant positive relationship with average scores. Significant relation was observed between nutritional status and attendance (P = 0·021). KII showed that SFP created convenient teaching–learning environment and reduced hunger in schools, while boosting enrolment, attendance and academic performance among the schoolchildren. CONCLUSION: The Addis Ababa SFP has positively contributed to educational outcomes. Strengthening the program would enhance nutritional outcomes and diminish educational inequalities.
