The authors performed Student’s t-test, X2 or Fisher’s exact tests and Pearson’s correlation to evaluate anthropometric variables, nutritional status and sport practice.

Findings

Female teenagers had higher values of body fat analyzed by skinfold thickness, fat mass, fat mass index and body fat percentage, while male had higher lean mass evaluated by fat-free mass and fat-free mass index. For both genders, it was observed that there was low intake of fruits and vegetables and daily intake of sweets, soda, salt snacks and fast food like sandwiches and pizza.
