Calculating fall risk in older adults

A formula and assessment tool for estimating fall risk among the older population has been developed by researchers at Osaka Metropolitan University.

An aging society has posed a new global problem: the risk of falling. It is estimated that one in three adults over the age of 65 falls each year, with resulting injuries becoming more prevalent. Preventing falls among older adults could extend life expectancy, as well as reduce medical and nursing care costs.

To tackle this growing issue, Associate Professor Hiromitsu Toyoda and Specially Appointed Professor Tadashi Okano from Osaka Metropolitan University’s Graduate School of Medicine, together with Professor Chisato Hayashi from the University of Hyogo, have developed a formula and assessment tool for estimating fall risks that is simple for older adults to use.

The tool was developed using data collected from older adults over a 10-year period from April 2010 to December 2019.

The research team reviewed a total of 7726 physical tests and data from the Japanese Government’s Kihon Checklist self-reporting questionnaire of 2381 participants who participated in community-based exercise groups.

The data was analysed under a contractual agreement between Sumoto City in Hyogo Prefecture and the University of Hyogo.

A history of falls and the inability to stand on one leg were previously reported as the primary indicators for fall risks, but the recent analysis found that poor oral and cognitive function were also contributing factors.

Additionally, short-term participation in the exercise program was found to be ineffective.

“We believe that this tool will provide valuable information to healthcare providers for screening older adults at risk for falls and assist them in prevention and follow-up care,” Toyoda said.

“We hope that municipalities will make extensive use of the system because preventing falls among older adults not only extends their life expectancy, but also helps control medical and long-term care costs.”

The results were published in Osteoporosis International.
