At what age does peak bone mineral density (BMD) typically occur?

Peak bone mineral density (BMD) typically occurs between the ages of 25 and 30 years old. During this time, bones reach their maximum strength and density, which is influenced by various factors including genetics, nutrition, and physical activity. After reaching peak BMD, bone density can begin to decline with age, particularly in the presence of risk factors such as menopause in women or sedentary lifestyle.

The correct choice reflects the general understanding in the field of bone health that the late 20s is a critical period for bone density development, making it essential for individuals to engage in weight-bearing physical activities and maintain adequate levels of calcium and vitamin D to support optimal bone health during these formative years. Hence, this choice aligns with the accepted benchmarks regarding bone density maturation and its implications for long-term skeletal health.
