Objective: To systematically review the determinants of nutrient intake among adolescent competitive athletes.
Methods: This study is a systematic review of observational and intervention studies. The PubMed and Scopus databases were searched over the last 20 years. Original research on nutrient intake in competitive athletes (10 to 19 years) in all languages was included. Two independent researchers selected the studies, assessed the risk of bias, extracted the data, and evaluated the quality.
Results: The initial search netted 5409 potentially relevant manuscripts. After removal of duplicates, 258 were read in full, of which 20 were included. All studies were observational; the most were cross-sectional (80%) and conducted in developed countries (75%) as the United States and European nations. Boys (63%) were more evaluated than girls (37%), and the sport that received the most attention was soccer (35%). As determinants for nutrient intake outcome, most studies analyzed the influences of sports-related factors, age, sex, and Ramadan. Others determinant were evaluated in isolated studies, such as food preference, menu settings and meal patterns. Only sport modalities were significantly associated with the nutrient intake. Age, sex, and Ramadan were not significantly associated with the nutrient intake. The analysis of the methodological quality of the studies indicated that the principal risk of bias was that the sample was not representative of the population.
Conclusions: Athletes do not adjust their nutrient intake to the demands of the training load and different training sessions. On the other hand, sport modalities significantly influenced nutrient intake.
