A nurse in a clinic is assessing a client. Which of the following findings should the nurse identify as a risk factor for osteoporosis?

A. Larger body size does not increase the risk for osteoporosis. In fact, individuals with a larger body may have more bone mass, offering some protection. B. Although a history of fractures may indicate fragile bones, childhood fractures do not significantly contribute to the development of osteoporosis in adulthood. C. Smoking is a well-established risk factor for osteoporosis. It reduces bone density and impairs bone regeneration, making smokers more prone to fractures and bone loss. D. While excessive alcohol consumption can increase the risk of osteoporosis, consuming one alcoholic beverage per day is generally considered moderate and does not pose a high risk for osteoporosis by itself.
