				        	Objective:To understand the energy and major nutrients intake of high school students in Shanghai, and to provide basis for formulating target nutritional interventions and health education.
				        	
				        
				        	Methods:The probability-proportional-to-size sampling technique was used to select 19 high schools, from which 9 boys and 9 girls from same class were randomly recruited for each grade. A total of 900 high school students were surveyed on their energy and major nutrients intake.
				        	
				        
				        	Results:The medians of intake of energy, protein, fat, carbohydrate, calcium, sodium, iron, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber were 2 353 kcal/d, 97.3 g/d, 95.4 g/d, 265.4 g/d, 602.1 mg/d, 4 373 mg/d, 24.3 mg/d, 495.6 μgRE/d, 1.08 mg/d,1.21 mg/d, 83.2 mg/d and 1.01 g/d, respectively. Among of them, the medians of intake of energy, calcium, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber for boys and girls were lower than reference standard(P<0.05). The medians of intake of energy and major nutrients in high school students who lived in countryside were less than those lived in suburban and urban(P<0.05), except carbohydrates and iron. The percentages of energy supplied byprotein, fat and carbohydrate were 16.9%, 37.2%and 46.0%, respectively.
				        	
				        
				        	Conclusion:The energy and calorigenic nutrients intake can meet the demand of daily consumption in high school students in Shanghai, but the intake of dietary fiber, some minerals and vitamins have a various degrees of deficiency. The proportion of energy supplied bycalorigenic nutrients is unbalanced.
