title: [Maternal nutrition as a determinant of fetal weight: role of trace elements and vitamins].
abstract: OBJECTIVE
  To evaluate maternal trace elements and vitamins food intake in the last month of pregnancy and assess their effect on fetal weight.
  
  
  METHODS
  It is a food intake survey led near 350 pregnant women. All women participated in a nutritional survey and were at term. To examine dietary intakes, food frequency questionnaires were completed before delivery on the diet during the last 24 hours. Authors compared the maternal intakes to the recommended allowance and analyzed the correlation between these intakes and fetal weight.
  
  
  RESULTS
  This study confirmed the influence of factors such as parity, maternal BMI and term of pregnancy on the fetal weight. The mean daily intakes of iron (10.7 mg/day), calcium (553 mg/day), zinc (6.2 mg/day), magnesium (284.3 mg/day) were lower than recommended. The mean daily intakes of vitamins C and E did not differ from recommended allowance. Only calcium intakes were significantly correlated to birth weight.
  
  
  CONCLUSIONS
  We noted a deficiency of most of these intakes compared to the recommended dietary allowance. Trace elements and vitamins C, E maternal-food intakes in the end of pregnancy don't seem to be a significant determinant of foetal weight.
