Final answer:
The statement that osteoporosis occurs more often in men in a ratio of 4:1 is false; it is more common in women, especially after menopause. Osteoporosis involves an imbalance in osteoclast and osteoblast activity, leading to weakened bones. Prevention includes proper nutrition and weight-bearing exercises.
Step-by-step explanation:
The statement that osteoporosis occurs more often in men in a ratio of 4:1 is false. Osteoporosis is more common in women, particularly as they age. Women begin to lose bone mass more quickly around the age of 50, coinciding with menopause. This is due to the cessation of estrogen production, which is essential for osteoblastic activity and the production of bone matrix. Although men can develop osteoporosis, women are at a higher risk, partly due to these hormonal changes.
Risk factors for osteoporosis include older age, female sex, family history of the disease, and certain lifestyle choices. Prevention strategies involve maximizing bone mass through adequate intake of calcium and vitamin D, and engaging in weight-bearing exercises to build bone density.
Osteoporosis can involve both excess bone resorption, primarily carried out by osteoclasts, and insufficient production of new bone tissue, the role of osteoblasts. This imbalance can lead to bones becoming weak, brittle, and more likely to fracture.
