When does type 2 primary osteoporosis generally occur?

• A. Before age 50
• B. After age 70
• C. During menopause
• D. In childhood

Answer: (B)

Type 2 primary osteoporosis, also known as senile osteoporosis, generally occurs in the later stages of life, typically after the age of 70. This form of osteoporosis is characterized by age-related bone density loss, which is influenced by various factors including hormonal changes, decreased physical activity, and nutritional deficiencies that often accompany aging.

In this stage, the body's ability to form new bone begins to decline, leading to an imbalance where bone resorption outpaces bone formation. This increase in bone fragility contributes significantly to the risk of fractures among older adults. Understanding the age at which type 2 primary osteoporosis typically manifests helps in the identification and management of individuals at risk for osteoporosis-related complications, as preventative measures and early interventions can be better implemented when the age-related onset is recognized.

Other age ranges, such as those before age 50 or during menopause, are associated with different types of osteoporosis, primarily type 1 or postmenopausal osteoporosis, which is typically influenced by hormonal changes resulting from decreased estrogen levels. Childhood does not align with the onset of primary osteoporosis, as bone density and strength are generally increasing during those years. This context emphasizes the importance of age in understanding the different phases and types of osteoporosis.
