title: [Macronutrients in mature milk of teenagers and adult mothers].
abstract: 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/100 ml and 1.9 +/- 0.7 g/100 ml for B median fat concentration in teenage group was 3.8 +/- 1.5 g/100 ml and in adults 3.9 +/- 1.3 g/100 ml. Median carbohydrates level in teenage was 6.8 +/- 0.8 g/100 ml and in B Group was 6.6 +/- 0.9 g/100 ml, 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.
