Murphy, J. Michael et al. Archives of Pediatrics & Adolescent Medicine, vol. 152, September 1998. This study provides strong evidence that higher rates of participation in school breakfast programs are associated with improved student functioning on a broad range of psychosocial and academic measures. Students who increased their participation in the universal free breakfast program had significantly greater increases in their math grades and significantly greater decreases in school absence and tardiness. Psychosocial problems like depression and anxiety also decreased to a significantly greater degree for children with increased participation in the program.
