A teenager, or teen, is a young person whose age falls within the range from 13â19. They are called teenagers because their age number ends with teen. Someone aged 18 or 19 is also considered a young adult. Usage by ordinary people varies, and also varies in different societies. Most societies traditionally had a formal ceremony to mark the change from childhood to adulthood.
Increased Growth Needs for Teens. Teens grow at astounding rates! Teenage girls grow approximately 23 to 28 cm during their teen years, and teen boys add approximately 26 to 28 cm to their height. Growth during the teen years accounts for about 20% of total height. Not only do teens grow up, but they grow out as well. Weight gain during the teens accounts for about 50% of a personâs ideal adult body weight. Lean body mass (muscle mass, bones, organs â everything except body fat) increases in both teen boys and girls.
