Men and women reach their peak bone mass in their late 20's.

Peak bone mass is influenced by a variety of genetic and environmental factors.

Osteoporosis is defined as more than 2.5 standard deviations below peak bone mass.

Around age 30, your bones reach their maximum strength and density, known as peak bone mass.

Gender: Peak bone mass tends to be higher in men than in women.

As a result, your bones become larger and heavier until about age 30 when you reach peak bone mass (density).

Hormonal factors: The hormone estrogen has an effect on peak bone mass.

Most people continue to build bone faster than they lose it until about age 30, a point that's known as "peak bone mass."

Weight bearing exercise can increase peak bone mass achieved in adolescence, and a highly significant correlation between bone strength and muscle strength has been determined.

Given the knowledge that high peak bone density reduces osteoporosis risk later in life, it makes sense to pay more attention to those factors that affect peak bone mass.

Calcium deficiencies in young people can account for a 5 to 10 percent difference in peak bone mass and can increase the risk for hip fracture later in life.
