The Survey Of Dietary Status In Liyang’s Students

【Objective】Reasonable diet is an important material basis to maintain human lifeand health for the various stages of growth. The nutritional status of schoolchildren isparticularly important as it could affect their learning, living and health conditions. Witheconomic development and improvement of living standards, the nutritional status ofstudents has been a significant improvement in recent years. However, diet andnutritional status of urban and rural students are some differences because of theimbalance of urban and rural economic development. This paper focuses on thenutritional and dietary situation of schoolchildren to find problems and to proposepractical policy guidance for schoolchildren nutrition food consumption.【Methods】The600students were selected in the age of10-16years old bycluster random sampling method from three secondary schools and three primaryschools in city and town of Liyang. The information of student, such as name, gender,age, height, weight was collected. Dialed dietary situation of three days were alsocollected through backcasting investigation by the professional health staffs. Everycooked meal volumes of each student was obtained and converted into raw food weightby the look-up table method to calculate the energy, protein, fat, carbohydrates, mineralsand nutrients. The overall dietary patterns and nutrient intake situation analysis andevaluation were based on comparison of nutrient intake and the "Chinese DietaryReference Intakes DRIS" by SPSS.【Results】The average height, weight, body mass index (BMI), obesity andmyopia prevalence of the survey from Liyang schoolchildren was149.7cm,42.2kg,18.7kg/m2,5.77%, and22.24%, respectively. There was no significant differencebetween urban and rural. The prevalence of myopia of students in secondary school wassignificant more than students in primary schools. Dietary pattern of urban and ruralstudents, the level of energy and nutrient intake were not significantly different. There were no significant difference between energy intake. The ratio of three calorigenicmacronutrients to total energy is similar with the "Chinese Dietary Reference IntakesDRIS" in primary and secondary schools. However, the calcium was less by60.7-79.4%and iron intake was more (110.8-156.2%). Urban male and female students of protein,fat, carbohydrate meals for energy ratio of12.3-15.9%,26.5%-32.4%,52.4-60.9whichmeet Chinese dietary guidelines recommended ratio. Body mass index (BMI) withenergy, fat, protein intake levels were generally positively correlated.【Conclusion】Good diet and nutrient intake of the students in primary andsecondary school in Liyang could meet the needs of the body. However, the calciumintake is low and the iron intake is high. Schools should pay attention to students’ healtheducation and training activities and seminars, working through the school’s strengthschannels for students scientific diet and dietary nutrition knowledge of the mission, andactively take nutrition interventions, appropriate to increase the vegetables, fruits,aquatic products, eggs food intake, promote intake of milk, beans, food, increasecalcium-rich food items, to maintain adequate energy and fat intake, increase calciumintake.
