title: Lifestyle and resulting body composition in young athletes.
abstract: BACKGROUND
  Key aspects in a lifestyle analysis are physical activity level and eating habits. An unhealthy lifestyle results in fat mass increase and in a predisposition to non-communicable chronic diseases even in young age. The purpose of this study was to investigate the lifestyle and body composition in young athletes.
  
  
  METHODS
  The subjects underwent to an assessment of body composition and they completed two questionnaires, one concerning the level of physical activity and the other regarding eating habits.
  
  
  RESULTS
  One hundred fifty-two young athletes (63 females and 89 males) aged 8 to 18 years (13.4±2.5 years, height 159±14 cm) were enrolled in this study. 80.3% of subjects were normal weight (13.4±2.6 years) and 19.7% subjects (13.5±2.5 years) were overweight or obese. Greater sedentary behaviors were found in the overweight or obese participants compared to normal weight (618±125 vs. 523±89 min; P<0.001) and a lower consumption of milk and yoghurt (5.0±3.2 vs. 6.9±4.1 times/week; P=0.031).
  
  
  CONCLUSIONS
  Although competitive sports often increase physical activity levels in young people, this activity does not seem to reach the daily recommended amount of physical activity during youth. Therefore, it is necessary to have a comprehensive approach to create a primary prevention strategy from even a young age.
