title: [Survey and analysis of the intakes of energy and macronutrients in rural boarding school students].
abstract: OBJECTIVE
  To preliminarily survey the intakes of energy and macronutrients in rural boarding school students and analyse the affect factors of discrepancies between different sex and age groups.
  
  
  METHODS
  A total of 1834 rural boarding junior high school first grade students were selected from 16 provinces, and stratified cluster sampling method was used. The method of weight recording and three days dietary recall were used to investigate the diet of boarding school students.
  
  
  RESULTS
  The ratios which reached the EER of energy intakes in boy and girl groups were 37.0% and 46.7% (P < 0.05) respectively, and the proportion of the intakes level of EER among the age groups of 11y ~ and 14y ~ for both boys and girls were 93.4%, 81.1% (P < 0.05) and 102.1%, 87.1% (P < 0.05) respectively. The ratios which reached the EAR of protein intakes in boy and girl groups were 57.7% and 61.4% ( P > 0.05) respectively, and the proportion of the intakes level of EAR among the age groups of 11y ~ and 14y ~ for both boys and girls were 124.8%, 107.3% (P > 0.05) and 134.8%, 112.1% (P < 0.05) respectively. The ratios which reached the EAR of total carbohydrate intakes in boy and girl groups were 85.0% and 77.5% (P < 0.05) respectively, and the proportion of the intakes level of EAR among the age groups of 11y ~ and 14y ~ for both boys and girls were 202.0% and 240.0% (P < 0.05), 180.1% and 205.4% (P < 0.05 ) respectively. The ratios which reached the AMDR of total fat intakes in boy and girl groups were 25.4% and 22.0% (P > 0.05) respectively, and among the age groups of 11y ~ and 14y ~ for both boys and girls were 21.8% and 30.5% (P < 0.05), 20.2% and 25.5% (P > 0.05) respectively.
  
  
  CONCLUSIONS
  Double burden of nutrient might exist in the rural boarding schools. The status of nutrition could be improved evidently, by fulfilling the relative national policies, promoting the balance of the nutrition supplying in schools, and enriching the boarding students' knowledge of nutrition.
