Do metabolic syndrome and its components have an impact on bone mineral density in adolescents?

In recent years, there has been growing concern about the occurrence of metabolic syndrome (MetS) at an early age and its effects on bone mass in adolescents. Adolescence is considered a critical period for bone mass gain. Impaired bone acquisition during this phase can lead to "suboptimal" peak bone mass and increase the risk of osteopenia/osteoporosis and fractures in old age.

Low-dose combined oral contraceptive use is associated with lower bone mineral content variation in adolescents over a 1-year period.

Background: Low-dose combined oral contraceptives (COCs) can interfere with bone mass acquisition during adolescence.
