title: [Breastfeeding (part one): Frequency, benefits and drawbacks, optimal duration and factors influencing its initiation and prolongation. Clinical guidelines for practice].
abstract: OBJECTIVE
  The objectives were to on assess the frequency and the duration of breastfeeding in France. On the other hand, the objectives were to identify its benefits and drawbacks, and to study the factors influencing its initiation and its extension.
  
  
  METHODS
  Bibliographic research in Medline, Google Scholar and in the Cochrane Library.
  
  
  RESULTS
  Breastfeeding concerns in France about 70% of children at birth (EL2). Its median duration is about 15 weeks and 3 weeks ½ for exclusive breastfeeding. At three months, only one third of children breastfed at birth are still being breastfed (EL2). Whether this is due to the composition of breast milk or the behavior of mothers with their children or their socio-cultural level, or even by all these components at once, breastfeeding is associated with better cognitive development children (EL2). This effect is even more reinforced that mothers breastfeed exclusively and prolonged (EL2). As part of the prevention of many diseases (ear infections, gastrointestinal infections, atopic diseases, obesity and cardiovascular diseases…), exclusive and prolonged breastfeeding (grade B) between 4 to 6 months is recommended (professional consensus). Breastfeeding is not a means of preventing postpartum depression (professional consensus). To reduce the incidence of breast cancer, prolonged breastfeeding is recommended (grade B). In order to increase the rate of initiation of breastfeeding as well as its duration, it is recommended that health professionals work closely with mothers in their project (grade A), the breastfeeding promotion messages include message to husbands (grade B), and to promote breastfeeding on demand without fixed interval between feedings (grade B). However, there is not enough data to recommend the use of a specific position during breastfeeding, or the use of one or two breast or to early start breastfeeding or not (professional consensus).
  
  
  CONCLUSIONS
  Exclusive and extended breastfeeding is recommended (grade B) between 4 to 6 months (professional consensus).
