Prevalence and Factors Associated With Low Aerobic Performance Levels in Adolescents: A Systematic Review.

Abstract

Low aerobic performance levels have been considered one of the risk factors for premature mortality, regardless of presence of other health problems. The critical analysis of studies on the prevalence of low aerobic performance and associated factors may contribute to the epidemiological knowledge and analysis / discussion of socio-cultural aspects that influence low aerobic performance. The aim of this systematic review was to identify studies on the prevalence of low aerobic performance levels and possible associations between low aerobic performance and demographic/ biological factors, lifestyle and excess body fat in adolescents (11-19 years). The search was conducted in PubMed and SciELO databases using descriptors "aerobic capacity" or "aerobic fitness", "cardiorespiratory capacity" or "cardiorespiratory fitness", "aerobic power" or "aerobic endurance" or "cardiorespiratory endurance" and "adolescents". After the search and exclusion criteria, 33 articles were selected. Factors that were associated with low aerobic performance levels were female gender, low income, low consumption of dairy products and/or bread/cereals, increased consumption of sweetened beverages, insufficient physical activity level, excessive screen time and excess body fat. The heterogeneity of factors related to low aerobic performance levels demonstrates the complexity of this topic and the need for further studies to obtain definitive conclusions.
