Risk factors for and protective factors against breastfeeding interruption before 2 years: a birth cohort study.

Background: Little is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age.

Methods: In this live birth cohort, mother and infant dyads were followed for 2 years.

Colostrum oropharyngeal immunotherapy for very low birth weight preterm infants: protocol of an intervention study.

Background: The oropharyngeal colostrum administration protocol to treat premature newborns is a possible and plausible strategy in neonatal health services, since the immunoprotective components of colostrum can be absorbed by the lymphoid tissues of the oropharynx. In this context, this study aims to describe the implementation of oropharyngeal colostrum immunotherapy in very low birth weight preterm newborns in a neonatal unit, as well as to test an algorithm in a public hospital.

Methods: The protocol is applied in a non-randomized, superiority clinical trial with historical control.

Exclusive breast-feeding is associated with reduced pacifier sucking in children: Breast-feeding and pacifier-sucking habit.

Background: Studies suggest that when children do not achieve the emotional satiety and adequate stimulus provided by breast-feeding, they exhibit sucking behaviors. This study aimed to estimate the association from 4 through 6 months of exclusive breast-feeding (EB) postpartum and pacifier-sucking behavior at 12 months of life.

Methods: A cohort study was conducted with 1,037 infants, born alive and monitored up to 12 months.

Increased risk of allergic rhinitis among children delivered by cesarean section: a cross-sectional study nested in a birth cohort.

Background: Few studies have evaluated the association between delivery by cesarean section (CS) and asthma, allergic rhinitis and chronic rhinitis and whether this association is different in children with and without a family history of asthma. This study aims to investigate whether children born by CS have a higher chance to develop asthma, allergic rhinitis and chronic rhinitis and to evaluate the influence of parental history of asthma on these associations.

Methods: This is a cross-sectional study of 672 children nested in a birth cohort evaluated at 6-years of age.
