title: Relationship of the intake of different food groups by pregnant mothers with the birth weight and gestational age: Need for public and individual educational programs.
abstract: OBJECTIVE
  This study was conducted to investigate the relationship between the intake of different food groups by pregnant mothers and neonatal low birth weight and premature births.
  
  
  METHODS
  In this cohort, the target population was 225 pregnant women, randomly selected from different geographical areas of the city of Isfahan, Iran (from April to September, 2012). The main variables in the study were weight and gestational age of the neonates and the type and amount of different food groups used by the mothers. All nutritional variables were compared according to different groups of infants (normal, premature, and low birth weight). In the multivariate analysis, multiple linear and logistic regression models were used to identify those different food frequency questionnaire (FFQ) variables independently associated with the newborn's weight and gestational age, adjusted by maternal consumption of calcium supplementation, folic acid, and omega-3, during pregnancy.
  
  
  RESULTS
  A total of 214 (47.7% boys) infants with complete information were included. They had a mean gestational age of 38.72 ± 1.2 weeks. The mean birth weight was 3.11 ± 0.384 kg. The percentages of premature and low birth weight (LBW) infants were 7 and 5%, respectively. At multiple logistic regression controlling for potentially confounding factors that were significantly associated with prematurity and LBW at univariate analysis (maternal consumption of calcium supplementation, folic acid, and omega-3, during pregnancy), type of nutritional groups containing dairy products, proteins, fish, and shrimp group, as well as fruits and vegetables, had a significant positive association with increasing the gestational age (P < 0.05). The group that consumed proteins, fish, and shrimp, as well as fruits and vegetables had a significant positive association with the newborn's weight (P < 0.05).
  
  
  CONCLUSIONS
  This study indicated the importance of proper nutrition on reducing the rates of LBW and premature births. Comprehensive educational programs at individual and public levels are warranted in this regard.
