In order to investigate the breakfast practice of Chinese students in four cities, and to provide scientific basis for developing School Breakfast Program, self-administrated questionnaire is administrated among 7,617 elementary and junior students in Guangzhou, Shanghai, Jinan and Haerbin. The results showed that 18.9% junior students and 16.6% elementary students did not have breakfast everyday and, the nutrition of their breakfasts is inadequate. It is suggested that further recognition should be given to the improvement of the breakfast of the students.
