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

Choice A reason: Smoking is a well-established risk factor for osteoporosis. It interferes with calcium absorption, reduces estrogen levels, and impairs bone remodeling, all of which contribute to decreased bone density. Choice B reason: A childhood fracture may not be indicative of osteoporosis unless associated with other risk factors or recurrent fractures. It is not considered a strong predictor in adults. Choice C reason: Moderate alcohol intake (one drink per day) is not typically associated with increased osteoporosis risk. Excessive alcohol consumption, however, is a known risk factor. Choice D reason: Large body stature is generally protective against osteoporosis due to increased mechanical loading on bones, which stimulates bone formation.
