A recent study conducted by Nicole Wright, PhD, MPH, and colleagues shed light on the impact of race and ethnicity on fracture risk among postmenopausal women. The findings, published in the Journal of Bone and Mineral Research, revealed significant differences in fracture rates among different racial and ethnic groups. This study, which analyzed data from the Women’s Health Initiative (WHI), emphasized the importance of fracture prevention for minority groups at higher risk.
The study found that white women had the highest rates of fractures among postmenopausal women, but other racial and ethnic groups were not far behind. Black, Pacific Islander, Asian, and multiracial women had significantly lower risks for any clinical fracture compared to white women. For example, Black women had a hazard ratio (HR) of 0.58, indicating a 42% lower risk of fractures compared to white women. Similarly, Pacific Islander, Asian, and multiracial women also had lower risks for fractures, highlighting the disparities in fracture rates among different racial groups.
In addition to clinical fractures, the study also looked at major osteoporotic fractures, such as those in the hip, clinical spine, forearm, and shoulder. The results showed that all racial and ethnic groups, except for American Indian/Alaskan Native women, had significantly lower risks for major osteoporotic fractures compared to white women. This highlights the importance of considering race and ethnicity when evaluating fracture risk and implementing preventive measures.
One of the intriguing findings of the study was the differences in fracture rates among Hispanic and Asian women. Asian Indian women had the highest age-standardized incidence rate for any fracture, comparable to white women, while Filipina women had the lowest rate. Among Hispanic women, Cuban women had the highest fracture incidence rate, comparable to non-Hispanic women, while women of unspecified Hispanic origin had the lowest rate. These disparities emphasize the need for tailored interventions to address fracture risk among different racial and ethnic subgroups.
According to the lead researcher, Nicole Wright, fracture prevention should be a priority for not only non-Hispanic white women but also for American Indian/Alaskan Native, Asian Indian, and Cuban women who are at higher risk. With the changing demographics of the U.S., especially in older adults, it is crucial to provide targeted interventions to address racial and ethnic disparities in osteoporosis management and fracture outcomes. This study serves as a valuable resource for future research and the development of interventions aimed at reducing fractures in high-risk populations.
While the study provided valuable insights into racial and ethnic differences in fracture risk among postmenopausal women, there were certain limitations that should be acknowledged. Factors such as education level, income, acculturation, nutrition, lifestyle, bone mineral density, and bone geometry were not adjusted for in the analysis. These factors could potentially confound the results and warrant further investigation in future studies.
The study conducted by Nicole Wright and colleagues highlights the significant impact of race and ethnicity on fracture risk among postmenopausal women. The findings underscore the need for targeted interventions to address fracture disparities among different racial and ethnic groups. By understanding the unique trends in fracture rates among minority populations, healthcare providers can implement effective strategies for fracture prevention and management. Further research is needed to explore the underlying factors contributing to these disparities and develop interventions to improve bone health outcomes for all women and men.
