Bone mineralization in childhood and adolescence

Area of Science:

• Bone biology and skeletal health.
• Endocrinology and adolescent medicine.
• Nutritional science and osteoporosis prevention.

Background:

• Osteoporosis prevention hinges on achieving adequate peak bone mass by early adulthood.
• Bone mineral acquisition continues through childhood and adolescence, with over half of calcium deposited during teenage years.
• Genetic factors play a role, but lifestyle variables significantly influence peak bone mass.

Purpose of the Study:

• To highlight the critical importance of adolescence for bone mineral accretion.
• To underscore the influence of nonheritable factors on skeletal health.
• To identify conditions that can impair bone mass development.

Main Methods:

• Review of established knowledge on bone mineral acquisition.
• Analysis of factors influencing peak bone mass.
• Identification of chronic conditions affecting skeletal development.

Main Results:

• Peak bone mass is established by early adulthood, with adolescence being a critical period for calcium deposition.
• Body mass, calcium intake, sex steroids, and physical activity are key nonheritable determinants of bone mineral.
• Chronic illnesses, malnutrition, and endocrine issues during adolescence can lead to irreversible bone mass deficits.

Conclusions:

• Adequate peak bone mass is essential for osteoporosis prevention.
• Adolescent bone health is influenced by a combination of genetic and modifiable lifestyle factors.
• Early identification and management of conditions affecting bone health in adolescents are vital.
