| With the development of economic construction and the improvement of living standards, the dietary pattern of urban and rural residents of China has undergone great changes, the nutritional status of children and adolescents have been significantly improved. According to the 2002 survey, the height of 3-18 years old urban and rural children and adolescents increase by 2.4% and 2.5% compared to the height of the corresponding population in 1992. The weight of the youth of urban increased 0-2.6kg, in rural areas increased 0.3-2.7kg. However, nutritional unbalance is still very prominent. In 2002, the average rate of overweight was 4.5%, the average rate of obesity was 2.1%. The average rate of overweight in city and countryside were 8.5% and 3.2%, the obesity rates were 4.4% and 1.4% respectively. On the other hand, anemia and other issues of malnutrition are still quite prominent. The anemia prevalence of 5 to 18 years old children and adolescents in city and countryside were 8.7%-18.4% and 13.7%-21.8%. In order to know the growth and development status of primary and secondary students of existing health problems in the Sujiatun District, Shenyang City, we surveyed the nutritional status of 6282 students of six primary and secondary schools, for further exploring the impact of primary and secondary health-related factors, to improve the quality of primary and secondary schools provide the scientific basis of health.Subjects and MethodsSubjects and TimeSujiatun District randomly selected elementary,6282 students (male 3194, female 3088) in two schools of middle and high schools for investigation.

Measurement and approaches(1)Height, weight, chest circumference, vital capacity, blood pressure, vision measurement based on "Chinese students in Physical and Health Research" in the Chinese students of physical and health survey conducted testing rules.(2)Hemoglobin concentration of peripheral blood test to take his left ring finger, using WHO recommended cyanide methemoglobin France (HICN), Unity 721 spectrophotometer using colorimetric determination.2. CriterionDetermine standards for physical development of the relevant evaluation criteria, based on "Shenyang City, rural male and female physical development of schoolchildren 7-18 years of age-related evaluation criteria". The nutritional status of the evaluation criteria, based on "Shenyang City, China, the nutritional status of primary evaluation criteria"3.Error controlBy the various indicators of trained professionals in the determination of staff for the special, the instruments required prior to use rigorous calibration.4. Statistical analysisStatistical analysis using statistical software "SPSS11.5",stratified by age, description of height, weight, anemia prevalence with age trends.ResultsSujiatun District, Shenyang City schoolchildren The height, weight, chest girth averages of schoolchildren aged 6 to 18 years of Sujiatun District, Shenyang City schoolchildren were to maintain a growth momentum. Malnutrition rates are higher than the 2002 school year 2007 school year, the rate of nutrient excess and visual low rate of dental caries rate in 2007 than 2002 academic year, trachoma and anemia detection rate lower than the 2002 school year 2007 school year.
