Which of the following is NOT a risk factor for osteoporosis in an older adult?

The correct choice, which indicates that "her race" is NOT a risk factor for osteoporosis, is based on the understanding that while osteoporosis affects individuals differently based on several factors, race alone does not serve as a direct risk factor in the same way that age, alcohol intake, and smoking do.

Age is a primary risk factor since bone density naturally decreases with advancing age. The excessive intake of alcohol contributes to bone loss and reduces the body's ability to absorb calcium and produce vitamin D, which are essential for bone health. Smoking is another significant risk factor, as it has been shown to contribute to decreased bone mineral density and increased fracture risk. These factors are modifiable and well-established in their impact on osteoporosis risk.

While certain racial and ethnic groups may have different prevalence rates of osteoporosis, race itself does not inherently increase or decrease an individual's risk—it's the associated lifestyle factors and genetic predispositions that play a more direct role. Therefore, distinguishing race from these other tangible risk factors highlights why it is the correct choice as not being a direct risk factor for osteoporosis in older adults.
