title: [Investigation of nutritional status of pupils and dietary survey in primary schools in poor counties of Guangxi and Yunnan].
abstract: OBJECTIVE
  To understand the nutritional status of pupils and to provide basic evidence for the nutritional interventions.
  
  
  METHODS
  The subjects of the study were 2046 pupils from 9 primary schools in poor counties of Guangxi and Yunnan. The contents of the investigation included medical physical examination, haematoglobin determination and dietary survey. Nutritional Status was evaluated according to WHO growth standards.
  
  
  RESULTS
  The prevalence of stunting and wasting in children from 6 to 14 years old in poor areas of Guangxi and Yunnan were 34.3% and 6.5% respectively. The anemia prevalence of them was 20.5%. The diet provided by the canteens of local school was mainly composed of plant food. Animal food was deficient. The cooking oil in local school was most of lard oil. The per pupil average daily intake of energy, protein, thiamin, riboflavin, vitamin C and calcium was 1491.29 kcal, 36.36 g, 179.15 ug, 0.57 mg, 0.37 mg, 53.67 mg and 163.14 mg respectively, which were lower than RNI or Al.
  
  
  CONCLUSIONS
  The chronic malnutrition of pupils in poor areas is still serious. The variety of food provided by the canteens of local school is quite single, and the quality of the meals is low. Intakes of energy, protein and micronutrient from school diet are insufficient for pupils.
