The Relationship Between Calciotropic Hormones, IGF-1, and Bone Mass Across Pubertal Stages.

Background: Little is known about the changes in calciotropic hormones during puberty and their relationship to bone mass during this critical period for skeletal accretion.

Objectives: Investigate changes in calciotropic hormones, IGF-1, body composition, and their associations with bone metabolism in adolescents.

Methods: Post hoc analyses were performed from data on 335 healthy school children, ages 10-17 years, with hypovitaminosis D who participated in a vitamin D randomized controlled trial.
