Objective To investigate the effects of dietary pattern on long-term nutritional status and growth of students.Methods Subjects were 7～16-year-old students in towns and at villages of Pinghu city. The effects of dietary structure on nutrition and growth status of students were analyzed based on the data about weight and height of students (1978～1998), data on nutritious lunch provided to students (1992～1998), and Statistical Yearbook of Pinghu City. Results In the two decades(1978～1998), the growth level of students was higher in the second decade than that in the first decade, which accorded with the increases in economic and living levels year by year. Meanwhile, the nutritional status of students was improved; secular growth change was found due to the supply of school nutritious lunch. Conclusions Implementation of school-based nutrition interventions is feasible and effective in improving the nutritional status of students and promoting their development.
