RESUMO
Breastfeeding is recognized worldwide as the best option for infant feeding. Expressing breast milk is an alternative for mothers to provide their infants all the benefits of maternal milk. During breast milk expression, mothers receive a distinct kind of sensory stimulation, because there is no direct bodily or affective interaction with their infants, many women report feeling isolated, generating a love-hate relation with pumping, and even low levels of satisfaction while expressing breast milk. While it is well known that the prefrontal, parietal, and temporal cortices play important roles in the emotional and cognitive processing of maternal stimuli, knowledge about how these cortical areas function during breastfeeding is lacking. This study was designed to characterize EEG activity in the prefrontal and parietal cortices and the affective scores of primiparous breastfeeding mothers during two conditions of milk expression: breast milk expression and direct breastfeeding. Participants reported higher valence and arousal and a pleasant state during direct breastfeeding. In the direct breastfeeding condition, both prefrontal areas showed a higher absolute power (AP) of the slow bands, with a lower AP of the alpha band in the parietal cortex. A lower correlation between frontopolar and dorsolateral areas with a higher correlation between prefrontal and parietal cortices was obtained mainly in the right hemisphere. This EEG activity could be linked to an internal state of focused attention and, simultaneously, open monitoring of the environment that suggests an integration of the motive-emotional and cognitive processes necessary for adequate mother-baby interaction during direct breastfeeding.

A presente pesquisa teve como objetivo avaliar conhecimentos que mães primíparas têm ao longo de primeiro ano de vida de seu filho sobre o processo de desenvolvimento infantil. Participaram da pesquisa 109 mães primíparas, maiores de 18 anos, com filho ou filha de até um ano de vida e que viviam na cidade de Itajaí (SC). Para sua realização foi utilizado o KIDI (Knowledge of Infant Development Inventory) e para identificar o nível socioeconômico dos pais foi utilizada a Escala de Avaliação de Status Socioeconômico de Hollingshead. Através de análise estatística, foi verificado que fatores sócio-demográficos, tais como: escolaridade e ocupação da mãe estão correlacionados significativamente com seu conhecimento sobre cuidados parentais. Foi constatado que o maior conhecimento das mães é sobre cuidados parentais (crenças, estratégias e comportamentos dos pais). Conclui-se que o status socioeconômico é um fator importante na determinação do conhecimento da mãe sobre sua criança.(AU)
The central focus of this study was to evaluate primiparous mothers' knowledge about parenting and child development throughout the first year of life of their children. Participants were 109 primiparous mothers, aged 18 years or older, living in Itajaí (Santa Catarina), with a child aged 1-12 months. The KIDI (Knowledge of Infant Development Inventory) was employed to evaluate mothers' conceptions of infant development and the Hollingshead Four Factor Index of Socioeconomic Status was used to evaluate the socioeconomic level of mothers' and their families'. Through statistical analysis it was verified that mothers' educational attainment and occupation correlated significantly with their knowledge on parenting and child development. The study revealed that mothers had more knowledge about parenting (beliefs, strategies and practices of the parents) when compared with other types of knowledge. The study concluded that the mothers' socioeconomic level is an important factor related to their knowledge about the child development.(AU)
