Hip fractures, especially in older individuals, significantly elevate the risk of mortality. Approximately 37% of men and 20% of women pass away within one year after a hip fracture. This also entails substantial pain and suffering, loss of mobility and independence, and increased healthcare expenses. Therefore, scientists from the University of Technology Sydney have dedicated their research to hip fracture prevention.
About Osteoporosis
Osteoporosis is a medical condition characterized by weakened and brittle bones due to a loss of bone mass. Individuals with osteoporosis have the highest risk of hip fractures, and pharmacological treatments can reduce this risk by approximately 50%. Osteoporosis is also a common issue among postmenopausal women.
However, Professor Tuan Nguyen, a leading global researcher in osteoporosis from the University of Technology Sydney (UTS), who led the study, stated that most hip fractures occur in individuals who do not have osteoporosis. This is why it is crucial for everyone, especially elderly individuals, to take measures to improve the health of their bones. Bone mineral density can be modified, and even minor improvements can reduce the risk of fractures.
Research Methodology
Researchers from UTS, in collaboration with colleagues from the Garvan Institute of Medical Research and UNSW Sydney, conducted an analysis of data from the Dubbo Osteoporosis Epidemiology Study, one of the most extensive osteoporosis studies globally. This study involved over 3,000 individuals aged 60 and older who were observed over an extended period to assess the frequency of fractures and risk factors.
Bone health is affected by lifestyle factors such as smoking, physical activity and nutrition, including vitamin D and dietary calcium intake. Stopping smoking, maintaining moderate physical activity, and eating a healthy diet can all help reduce bone loss.

How Bone Strengthening Helps Prevent Hip Fracture
Participants maintained a healthy lifestyle, remained physically active, and underwent regular check-ups.
Researchers discovered that between the first cohort in 1988-92 and the second cohort in 1999-2001, there was a 3% increase in bone mineral density. During the same period, the number of hip fractures decreased by 45%. Such a reduction is typically associated with a 10% increase in bone mineral density.
A small increase in bone mineral density led to a significant decrease in the number of hip fractures. The authors believe that this research will be of interest to policymakers in the healthcare sector and medical professionals. Of course, it is also valuable for individuals who want to reduce their risk of hip fractures.
Some people who are following medication regimens or engaging in lifestyle modification programs and notice a slight change in bone mineral density might believe that these measures hold little benefit for them. Nonetheless, even these minor effects can lead to a substantial reduction in fracture risk for the community

The findings also imply that the categorization of bone mineral density into osteoporosis or non-osteoporosis based on an arbitrary threshold is not an optimal approach for identifying people at high risk of fracture.
