Abstract

Objective: Describe and analyze the food intake, nutritional status and physical activity level of physically active adolescents and provide subsidies for the implementation of actions in Nutrition and Health. Methods: Cross sectional study with 37 adolescents enrolled in a Project Initiation Sports between October and December 2010. Was administered a questionnaire on health and nutritional status. To evaluate the nutritional status was used the following measures: Corrected Arm Muscle Area (AMA-c), Body Mass Index (BMI), Abdominal Circumference (AC), Subscapular Skinfold (SS) and Triceps Skinfold (TS). The dietary intake assessment was performed by applying a 24 hour dietary recall and compared with the recommendations by the DRI (2002). The level of physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). Results: The study included 37 male adolescents aged between 13 and 18 years, mean 15 years and standard deviation of 1,5, classified as active (73%) and very active (27%). The group average performed three meals per day and had mismatches in food intake for calories (81,1%), to the protein (75,7%), to carbohydrates (89,2%) and lipids (86,3%). The food groups that showed inadequacies consumption by adolescents was vegetables, fruits, milk, legumes and sugar and sweets. The inadequacies of the anthropometric variables were observed in 10,8% adolescents for the BMI, 16,2% for the AMA-c, 8,1% for TS, 2,7% for SS and 16,2% for AC. Conclusion: Although most adolescents are eutrophic according to anthropometric indicators, inadequate food intake represents a qualitative and quantitative nutritional risks to the population and serves as a subsidy for local interventions with schools sports.
