title: [Determination of the concentrations of proteins, carbohydrates and fat in milk of mothers in relactation].
abstract: In a prospective, randomized and comparative trial the milk of 40 lactating mothers of hospitalized children at the Department of Pediatrics, University Hospital in Maracaibo, Venezuela was analyzed in a year period. They were divided in two groups of 20 mothers each: Group A, mothers in a relactation situation, and Group B (Control): Exclusive breastfeeding. Both types of milk were analyzed in a blind fashion to determine fat, proteins and carbohydrates. Results show that fat concentration (g/dL) was significantly more concentrated in Group B than in A, from 3.6 +/- 1.5 to 5.5 +/- 1.0 (p < 0.001), while in contrast, the carbohydrates concentration (g/dL) was decreased from 6.4 +/- 5.7 to 5.7 +/- 0.8 (p < 0.001). Moreover, proteins concentration (g/dL) was not significantly modified, since in group A it was 2.1 +/- 1.2 as compared to group B (2.4 +/- 0.3.) Caloric value was also significantly decreased from the control value of 83.2 +/- 9.4 to 66.7 +/- 17.8 in the relactation group (p < 0.001). In conclusion, it a clear difference between the two types of milk in this study.
