At what age does bone mass typically reach its peak in both men and women?

• A. 25 years
• B. 30 years
• C. 35 years
• D. 40 years

Answer: (B)

Bone mass typically reaches its peak in both men and women around the age of 30 years. This peak bone mass is crucial because it sets the baseline for bone health; higher peak bone mass is associated with a lower risk of osteoporosis and fractures later in life.

During the years leading up to 30, individuals experience significant bone formation, influenced by factors such as genetics, nutrition, hormone levels (particularly estrogen and testosterone), and physical activity. After reaching peak bone mass, bone resorption often begins to exceed bone formation, leading to a gradual decline in bone density as people age.

Choosing the age of 25, 35, or 40 does not accurately reflect this biological process, as peak bone mass is generally considered to occur before 30 years of age. Therefore, understanding the significance of peak bone mass at around 30 years is important for strategies in promoting bone health and preventing conditions like osteoporosis later in life.
