Results The students＇ average energy intake was higher than the recommended supply{ RNI） , all the students＇ energy met the RNI. The proportion of nutrient supply energy was basically reasonable, the intake of Vit B1, Vit C, iron, phos- phorus and zinc were sufficient, but the intake of fat, calcium, Vit B2 and breakfast energy intake were insufficient. The hemoglobin level was different by genders. The prevalence of anemia was 11.74% and 16.67% for male and female respectively. Conclusion Eastern Guangdong mountainous rural junior high school students have better nutritional status, dietary structure is basically rational, but dietary monitoring and intervention strength and breadth is not enough.
