Influência do período do dia, da idade gestacional e da idade materna no valor calórico do leite humano

Abstract

Objective: To analyze the influence of maternal age, gestational age and time of day on the caloric value of human milk. Methods This is an analytical, longitudinal study with a quantitative approach with puerperal women whose newborns were hospitalized and who were milking at the Human Milk Bank (HMB) of the University Hospital of the Federal University of Grande Dourados (HU-UFGD). Data from the study participants was collected, as well as 20 mL of milk for the research divided into two samples, collected in a single day, morning and afternoon milk, for analysis of the caloric value of the milks, crematocrit was used.. Results: The energy value, according to the period of the day, was around 510.67kcal/L±94 for milk in the morning and 732.92Kcal/L±162.11 for the afternoon milk, but there was no statistical difference. The caloric value of milk correlated with gestational age and maternal age showed no correlations. Conclusions: Maternal and gestational age and time of day did not present a statistically significant correlation with energy value. Studies should be encouraged to establish variables that can interfere with the caloric value of human milk.
