The rates of students who met the recommended nutrient intake （RNI） of vitamin A, vitamin B₁, vitamin B₂, vitamin C and selenium were 34.8%, 27.4%, 33.5%, 24.4% and 47.0%, respectively. Only 2.4% of the students met the RNI of calcium. More than half of the students met the RNI of iron, zinc and copper. The rate of girls who met the RNI of iron was lower than the boys（P<0.05）.
