title: [Breastfeeding prevalence during the first year of life in Aragon. CALINA study].
abstract: OBJECTIVE
  To study the current prevalence of breastfeeding (BF) in Aragon (Spain) during the first 12 months of life, and analyse its demographic, perinatal and social influential factors.
  
  
  METHODS
  Obstetric, perinatal and feeding aspects were evaluated in a longitudinal and observational study, in a representative cohort of infant population from Aragon born between March 2009 to March 2010, controlled until 12 months of age (N=1.602).
  
  
  RESULTS
  Exclusive or predominant BF was more frequent than the rest of feeding modalities during the first 4 months of life. Maintenance prevalence of any BF modality was 82.5% at 1(st) month of age, 71.8% at 3(rd), 54.3% at 6(th), and 27.8% at 12 months of age. Maternal variables that were significantly associated with BF maintenance both at 1 and 6 months of age were: delivery modality (higher probability in case of vaginal delivery), academic level (higher probability if university studies), origin (higher probability in mothers from Africa), adiposity (higher probability of normal weight or overweight mothers compared with obese ones), and not to smoke during gestation.
  
  
  CONCLUSIONS
  BF prevalence in Aragon (Spain) during the first 12 months of age is high and has increased compared with previous data. BF continues in more than half of infants at six months and in a quarter of infants at 12 months of age. Maternal factors that significantly influence BF initiation and maintenance are, delivery modality, academic level, origin (immigration), adiposity and smoking habit.
