NEVES, Alice Cristina Medeiros das; MOURA, Erly Catarina; SANTOS, Wallace  and  CARVALHO, Kênia Mara Baiocchi de. Factors associated with exclusive breastfeeding in the Legal Amazon and Northeast regions, Brazil, 2010. Rev. Nutr. [online]. 2014, vol.27, n.1, pp.81-95. ISSN 1415-5273.


The objective of this study was to identify the factors associated with exclusive breastfeeding in children aged less than six months from the Brazilian Legal Amazon and Northeast regions.


The study used data from a survey that assessed prenatal and infant (<1 year) care in 2010. Sociodemographic, prenatal, delivery, and puerperium care factors with p<0.05 in multivariate analysis were associated with exclusive breastfeeding.


For both regions, the prevalence of exclusive breastfeeding decreased with age, which was the main variable associated with early weaning. In the Legal Amazon, exclusive breastfeeding prevailed among: mothers aged 35 years or more; mothers living in state capitals; and mothers who breastfed on the first hour of life. In the Northeast, the probability of exclusive breastfeeding was greater for mothers aged 35 years or more.


The factors associated with exclusive breastfeeding were child's and mother's age in both regions; and residence location and breastfeeding in the first hour of life in the Legal Amazon, suggesting the need of differentiated strategies for the promotion of exclusive breastfeeding.
