What is a common demographic for individuals with osteoporosis?

Individuals aged 65 years and older represent a common demographic for osteoporosis primarily due to the physiological changes associated with aging. As a person ages, bone density generally decreases, and the body becomes less efficient at absorbing calcium and producing bone-forming cells. This loss of bone density can lead to an increased risk of fractures and osteoporosis, which is characterized by fragile bones.

Additionally, post-menopausal women are particularly at risk due to the decrease in estrogen levels, which plays a crucial role in maintaining bone density. Thus, the combination of aging and hormonal changes significantly contributes to the prevalence of osteoporosis in this age group.

In contrast, the other options refer to demographics or situations that are generally unrelated to the common occurrence of osteoporosis. For example, those under 30 years of age typically have higher bone density and are less likely to be affected by osteoporosis, while physically active individuals might better maintain bone health due to the benefits of weight-bearing exercise on bone strength. Likewise, individuals with high calcium diets can help prevent osteoporosis rather than be a demographic commonly affected by it.
