title: [Influence of breastfeeding and diet in the development of allergies in children].
abstract: OBJECTIVE
  To evaluate the relationship between breastfeeding and the development of allergic diseases (AD).
  
  
  METHODS
  A cases-controls study.
  
  
  METHODS
  Santander University Hospital, Bucaramanga, Colombia, South America. Level II health care.
  
  
  METHODS
  A total of 1460 boys and girls between 3 and 7 years old attending an outpatient clinic.
  
  
  METHODS
  Partial (BF) and exclusive breastfeeding (EBF); relationship between the presence of allergic diseases and BF and EBF, adjusting for the confounding factors due to other exposures using logistic regression.
  
  
  RESULTS
  Out of a total of 1460 patients, 41.6% (95%CI 39.0-44.2) received EBF, while 44.4% (95%CI 41.9-47.0) were partially breastfed. Among those who had an allergy, 34.8% (95%CI 32.4-37.3) had rhinitis, 27.8% (95%CI 25.6-30.2) asthma and 11.6% (95%CI 10.0-13.4) atopic dermatitis; 7.0% (95%CI 5.1-9.3) had the three conditions. To breastfeed exclusively for >or= 3 months is a protective factor for AD (OR 0.70, 95%CI 0.48-1.03). Breastfeeding for 3 months, regardless of whether or not it is exclusive, is a risk factor for AD (OR 2.05, 95%CI 1.47-2.86).
  
  
  CONCLUSIONS
  The recommendation to exclusively breastfeed for as long as possible continues to be valid, as there was a significant preventive impact on the development of AD with the length of time breastfed. Prospective studies including lung function tests and immunological analyses need to be performed to confirm these findings.
