RESUMO
Human migrations and different migratory flows have been as old as the practice of breastfeeding (BF). The reasons for migrating, the conditions, and its protagonists are so diverse, often constituting situations of vulnerability and risk for health decision-making at both the individual and collective levels. The relationship between BF and human migration is totally dynamic and includes multiple factors, which is why there is a need to characterize territorially its prevalence rate and variability depending on the context. The migration profiles that can be configured from factors, such as schooling, employment, the host country's health system, and support networks, among others, have heterogeneity between countries that make it necessary to identify them. This study is an in-depth review of the report on the practice of BF in migrant women. The Arksey and O'Malley method was used to perform the PubMed and SciELO searches. The search terms were "exclusive breastfeeding (EBF)," "breastfeeding," "migrant women," and "human migration," and original articles published in English, Spanish, and Portuguese were included. Of the 43 selected articles, differences were found between the various migrant groups, in variables such as socioeconomic level, education, access to health services, maternal knowledge, father factor, culture, and intention to breastfeed. The heterogeneity of the practice of BF between countries, as well as in intraregional migratory flows, establishes different protective or risk factors depending on where the phenomenon develops and its conditions.
RESUMO
Breastfeeding is the fundamental, physiological, and psychosocial process by which the mother feeds the newborn. Early initiation of breastfeeding is recommended within the first hour of life and exclusive breastfeeding up to six months of age due to its optimal contribution of nutrients for the development of the newborn. Despite this, there are factors that affect this process which involve the nutritional, physical, and psychological state of the mother, such as food security or food insecurity, however, it is unknown if it will have a decisive impact on these factors concerning the cessation of breastfeeding or total duration of breastfeeding. This study is an in-depth review of the available information related to food security as a determinant in breastfeeding practices. We did a scoping review between December 2022 - January 2023. The principal inclusion criteria were: the use of the English language, qualitative and quantitative methods, and analytical studies. All the articles were available in full text and the manuscripts ranged from 1997 and 2022. Twelve studies were included: eight quantitative, two qualitative, and two mixed. In the quantitative studies, significant positive and negative associations were found between food insecurity, exclusive breastfeeding, early initiation of breastfeeding, cessation of breastfeeding, and total duration of breastfeeding. For their part, qualitative and mixed studies describe that women with severe food insecurity tend to feel weak and may have a poor perception of their diet and, consequently, their breastfeeding practices are lower. Moreover, there are qualitative studies that mention that the higher the food insecurity, the more frequently breastfeeding occurs. The inconsistency in the results may be due to factors involving the characteristics of each population, the instrument used to measure food security, and the variables by which the models were adjusted. It is necessary to carry out more studies on the subject since it is obvious that the relationship between the variables needs to be clarified.
