title: Bone metabolism during adolescence: the known, the unknown, and the controversial.
abstract: Adolescence is a critical period for determining peak bone mass. During this time, bone formation prevails over resorption, and approximately 40% of the total bone mass is accumulated. Several factors affect the accretion of bone mass during adolescence. Although genetic predisposition, age, race, and ethnicity cannot be modified, factors such as nutrition, physical activity, and lifestyle choices can be changed. Promoting a healthy lifestyle, regular weight-bearing physical activity, and a healthy diet with optimal calcium and vitamin D intake may prove to be the best way to achieve a maximal peak bone mass. This review discusses the known, the unknown, and the controversial regarding bone metabolism during adolescence.
