A recent study of women 55 and older found that while fewer women are dying from problems linked to low bone mineral density (BMD), more are living with related disability. The study analyzed Global Burden of Disease data from 1994 through 2023 to track deaths and disability associated with low BMD among women 55 and older in China and G20 countries.
When bone density is low, the risk of breaks increases, prompting scientists to examine how much illness from these fractures stems from weak bones. Their key conclusion reveals that while low bone density is now less deadly, it is increasingly tied to long-term limitations.
Disability on the Rise
Between 1994 and 2023, China experienced a drop in fatality rates linked to low bone density, but saw a rise in cases where people faced lasting physical restrictions. Similar trends appeared in other G20 nations, where deaths stayed consistent while disability cases climbed.
For women aged 75 to 84, the sharpest rise in disability related to low bone density was observed. The study also showed that newer generations face greater chances of enduring disability, despite having a reduced likelihood of dying compared to past cohorts.
Population Size and Age
The total number of women impacted grew significantly. In China, deaths from low bone density more than doubled over the study period, despite a lower fatality rate. This shift reflects China’s aging population—more older women today mean higher absolute numbers of deaths, even if the percentage has fallen.
Experts predict that the number of women affected by low bone density in China will keep rising until at least 2035. While death rates are expected to continue falling, disability will remain a pressing health issue.
Combating Disability
Death rates are expected to keep declining. Disability remains a significant concern. Bone health is about staying capable.
Maintaining Strength and Mobility
Good bone health isn’t just about preventing fractures; it’s also about preserving function. The study highlights that avoiding breaks is important, but keeping muscles strong and mobility intact is equally critical if an injury does occur. Muscles help with balance, while robust bones help absorb falls.
