Which population groups are most affected by osteoporosis?

The answer identifying Caucasian and Asian populations as most affected by osteoporosis is based on significant epidemiological studies and research findings. Osteoporosis is a condition characterized by decreased bone density and increased risk of fractures, which has been shown to vary across different ethnic and demographic groups.

Caucasian women, in particular, exhibit the highest incidence of osteoporosis-related fractures, partly due to lower peak bone density and hormonal changes associated with menopause. Similarly, Asian populations also display a higher prevalence of osteoporosis, although cultural dietary factors and lifestyle may contribute variably to bone health, such as lower calcium intake.

This prevalence is often linked to genetic predispositions that influence bone mineral density, as well as environmental factors that may not be as prominent in other racial or ethnic groups. Hence, the demographic outlined in the correct choice represents those populations that have been thoroughly studied and observed to present higher rates of osteoporosis and related complications.
