ABSTRACT
ABSTRACT OBJETIVE To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth. METHODS A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study. RESULTS A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29-31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202-1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant's weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%). CONCLUSION Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g-1,655g at birth, especially in those with lower severity scores.

Foram estudados 181 neonatos a termo, nascidos no serviço de neonatologia do Instituto Materno Infantil de Pernambuco (IMIP), no período de 0l.03.90 à 31.12.90. Determinaçäo da atividade de G.6.PD foi efetuada no sangue do cordäo, utilizando a técnica de reduçäo de metemoglobina. Constatamos 8 casos de enzimopenia (4,42%). Análise dos aspectos clínicos e laboratoriais foi realizada em apenas 7 casos. Todas as mäes dos neonatos com a deficiência foram de cor näo branca e a doença predominou nos recém-nascidos do sexo masculino (71,4%). Em todos os casos o comportamento clínico foi benigno. Icterícia foi observada em 5 casos (71,4%) e ausência da mesma em 2(28,6%). A icterícia foi precoce em apenas 1 caso (20% dos neonatos com icterícia). Anemia e dados laboratoriais de hemólise benigna foram observados em 1 caso (14,28%). Houve indicaçäo de tratamento com fototerapia em somente 1 caso (20%) dos neonatos com enzimopenia e que apresentaram icterícia
