Objectives: to describe the prevalence of exclusive breastfeeding in the community of Castilla y León, and to determine the factors that condition its duration.
Methods: descriptive, observational study carried out in Castilla y León (Spain) in children aged 6 to 12 months attending the consultation of any member of the Health Sentinel Network of Castilla y Leon in 2007.
Results: the percentage of women choosing exclusive postpartum breastfeeding was 81.2%, 10.7% mixed feeding and 8.1% artificial feeding. The drop-out of breastfeeding was progressive month by month and only 36.5% of children who initiated it reached six months.
Conclusions: the rates of exclusive breastfeeding and the maintenance up to the six months of life are still away from the proposed global standards. It is essential to improve the involvement of health personnel and general society in encouraging breastfeeding.
