[Macronutrients intake in school teenagers in Soria capital].
OBJECTIVE
To study the macronutrients intake in Soria teenagers from 10 to 19 years, as well as their body mass index (BMI).


METHODS
A seven-day diet questionnaire filled in by an accidental sample of teenagers (54 boys and 56 girls) from public schools in the capital. Working out the average daily intake of energy, carbohydrates, lipids and proteins by the software of "Alimentación y Salud" which also gives values of individual recommended dietary allowances (RDAs) related to each individual's particular characteristics. Use of Student's t-test to compare the average values of the estimated intakes of different nutrients and their RDAs.


RESULTS
In general, the intakes of energy, proteins and lipids are statistically significant over the RDAs, while the carbohydrates intake is under the recommendations. With reference to the type of lipids, the intake is over the RDAs for cholesterol, monounsaturated fatty acids, and saturated fatty acids, but not for polyunsaturated fatty acids. Among girls from 13 years of age more than 12% have a higher BMI than 26 kg/m2, but between 10 and 12 years of age more than 20% of the students have this parameter under 16 kg/m2.


CONCLUSIONS
According to the results, it would be useful to implement some nutritional intervention among the adolescents in Soria capital to promote a healthy feeding in order to avoid possible disorders (obesity, anorexia, etc.).
