Final answer:
Higher bone mineral density at age 25 is predictive of better bone health at age 65 because bone density peaks at around 30 years of age, and women tend to lose bone mass more rapidly than men after menopause. Factors such as exercise and nutrition play important roles in maintaining bone health.
Step-by-step explanation:
Higher bone mineral density at age 25 is predictive of better bone health at age 65 because bone density peaks at around 30 years of age, and after that, it tends to decrease. Women typically lose bone mass more rapidly than men, especially after menopause when estrogen levels decrease. The peak bone mass achieved at a younger age can help offset the natural decrease in bone density that occurs with aging.
Factors that influence bone health include exercise and nutrition. Regular exercise, particularly weight-bearing exercises and resistance training, can stimulate the deposition of more bone tissue and help slow down bone loss. Adequate intake of calcium and vitamin D through a balanced diet is also crucial for bone health.
