2 nutrition supply. Methods Totally 2119 primary and middle school students were selected from Shaoyang city by stratified random cluster sampling method. The concentrations of calcium, iron, zinc, copper and lead in whole blood were detected by whole blood elements analyzer, dietary energy and the contents of protein, fat and carbohydrate were tested by calories analyzer, and the contents of calcium, iron and zinc in food were detected by atomic absorption spectrometry. Results The proportions of thin, overweight and obesity of school-age children aged 6~15 in Shaoyang city were 5.29%, 5.24 % and 5.69 %, respectively. The proportions of population who were lack of calcium, iron and zinc were 8.31%, 9.57% and 4.26%, respectively. There were three kinds of lunch meal modes. Mode A consisted with milk and snack, and its proportions of three nutrients were closed to the balanced diet mode, but the energy and nutrient supply were far lower than the dietary reference intakes (DRIs). Mode B was composed of milk and food, which was relatively sufficient, and the average contents of dietary energy, protein, fat, carbohydrates and calcium, iron, zinc were kcal, g, g, g, mg, 8.25 mg and 2.03 mg, respectively. Mode C only consisted of pure meals, and the average contents of main nutrients and dietary energy were between model A and B, and there was a same problem that the proportion of carbohydrates was low and fat ratio was high with mode B. Three modes of lunch meal were mainly composed of grains, but the intake frequency and quantity of food such as whole grains and the mixed beans, potato, fruits, and nuts were very low, and the intake of dairy products was below the national recommended standard ( 300 g for each person every day). Conclusion The nutritional status of school-age children in Shaoyang city are not very nice and the dietary patterns are unreasonable. Schools should carry out the nutritional education and intervention so as to promote the balanced nutrition.
