This is a comparative, prospective and non-experimental study that evaluated the level of macronutrients in teenage mothers’mature breastmilk. The sample was represented by mature milk of 52 healthy and eutrophic mothers, divided in two groups: A n=24 constituted by adolescent mothers’s milk among 10 and 18 years and B n=28 formed by adult mothers’s milk among 19 and 35 years who accompanied their children 1-6 months of age hospitalized, from august 2009 to august 2010. The samples were analyzed to determine concentrations of carbohydrates, lipids and proteins. The maternal characteristics of group A and B respectively were: mestizo ethnicity 59.4% and 39.9%, average BMI: were 23.55 ± 1.01 kg/m2 and 24.2 ± 0.38 kg/m2. Primiparous were 87.5% in A and 35.7% in B. Age of children aged 1-2 months was 66.6% (A) 71.4% (B). Maternal age: group A 75% had between 16 and 18 years and group B 28.5% were between 19 and 21 years. About macronutrient concentrations, median protein level in A was 1,8 ± 0,7 g/100ml and 1,9 ± 0,7 g/100ml for B median fat concentration in teenage group was 3,8 ± 1,5 g/100ml and in adults 3,9 ± 1,3 g/100ml. Median carbohydrates level in teenage was 6,8 ± 0,8 g/100ml and in B Group was 6,6 ± 0,9 g/100ml, being non statistically significative in all three cases. The macronutrient concentrations and energetic value in teenage mothers’s mature breastmilk were similar than the adult mother’s milk.
