Comparison of the Macronutrient Content of Colostrum: Locals with Refugees

Background: Breast milk (BM) is considered the ideal and natural way of feeding for all infants. Although previous studies evaluated the factors influencing the content of BM, data concerning the effect of being a refugee on macronutrient contents of BM are rather inadequate. Therefore, we aimed to compare the macronutrient content of colostrum samples of Turkish and Syrian mothers. Materials and Methods: BM from lactating mothers who delivered term newborns was collected within the first 48 hours of lactation. Milk protein, fat, carbohydrate, and energy levels were measured by using a mid-infrared human milk analyzer. Demographic characteristics of the mothers and the infants were recorded. Results: Colostrum samples of 180 lactating mothers (Turkish: 96, Syrian: 84) were obtained. There were no significant differences between the groups in terms of body mass index of the mothers, mode of delivery, and infant gender. However, Syrian mothers gained less weight during pregnancy compared with Turkish mothers (p = 0.029). The median protein, fat, and energy levels of colostrum samples were found to be significantly higher in Turkish mothers than in Syrian mothers (p = 0.001, p = 0.017, p < 0.001, respectively). Cesarean delivery and being a Syrian refugee were independently associated with lower protein content of colostrum in logistic regression analysis. Conclusion: Lactating mothers who delivered their babies through vaginal route were found to be advantageous in terms of colostral protein content. Also, an association between being a refugee and lower protein content of colostrum was remarkable.
