Influência do estado nutricional materno sobre o conteúdo energético do leite humano

Abstract

Objective: To evaluate the influence that maternal nutritional status has on the energy content of human milk and to verify the difference in the energy content of foremilk and hindmilk. Methods: Analytical, transversal study of quantitative approach, carried out at the University Hospital of the Federal University of Grande Dourados, with the 40 internal donors of the Human Milk Bank. Sociodemographic data, anthropometric measurements and samples of human milked milk were collected. The energy content of human milk was determined by means of crematocrit. For statistical analysis the Student's T and Pearson's Correlation tests were used. Results: The average age of the participants was 28.4 ± 6.8 years. Most women (70%) were overweight. Statistical analysis of the data showed a statistically significant difference between the caloric values of the anterior and posterior human milk samples. When correlating the maternal nutritional status with the mean caloric value of the samples of human milked milk there was not association between the two variables (r = 0.014; p = 0.93). Conclusion: The average caloric value of the foremilk showed a difference from the hindmilk, without influence of maternal nutritional status.
