Healthy Behaviors in Adolescence

Other than the first year of life, there is no other developmental period during which individuals grow more than during the period of adolescence.1 These years are the time to form positive habits that will improve adolescents’ long-term health and well-being. Three behaviors are especially important to support health into adulthood: eating a nutritious diet, being active, and getting a good night’s sleep.2,3,4 On a typical day, almost 40 percent of calories consumed by 2- to 18-year-olds come from solid fats and sugars, and high school students sleep fewer hours per night than they need5,6 Almost one-third of adolescents spend at least three hours a day watching television.7 Family factors, like siblings being active and support from parents, can help adolescents get and stay active.8

Resources on Nutrition in Adolescence

  • The Centers for Disease Control and Prevention’s Communities Putting Prevention to Work Online Resource Center provides tools to support environmental changes that address obesity. These resources describe why environmental changes are at the heart of making healthy living easier, and how to execute those changes.
  • The U.S. Department of Agriculture has several sites dedicated to helping Americans improve their diets. The Dietary Guidelines for Americans includes age-specific recommendations about overall calorie consumption and individual nutrient intake. ChooseMyPlate.gov helps users put those guidelines into practice.
  • Nutrition.gov provides information on all foods and has a designated Teens page with interactive learning tools for adolescents, and resources for parents and teachers.

The Adolescent Health Library has additional resources on healthy behavior and healthy eating.
