The FITTEST Trial: Supporting older people to participate in frailty prevention programs

In the FITTEST trial, health professionals and researchers will be studying how to improve the health and wellbeing of older people by preventing frailty.

We know that programs that promote good nutrition, regular exercise, optimisation of medicines, and social support networks can reduce frailty levels. However, these programs are not routinely available and, where they are, people do not always join in.

The FITTEST trial will compare dfferent ways to support older people to participate in frailty prevention programs.

Professor Ruth Hubbard

"Frailty is the most significant challenge to 'ageing well' in Australia. More than 20% of people become frail as they age. With the FITTEST trial, we want to find the best way to slow the progression of frailty by supporting older people with what we call 'The Four Pillars of Frailty Prevention and Management'. These are good nutrition, regular exercise, the right medicines, and good social networks."

About the trial

The FITTEST study will investigate the implementation and effectiveness of a multicomponent frailty program, integrating exercise, nutrition, optimisation of medicines and social connectedness. People living in the community aged ≥ 65 years with mild frailty will be randomised to a supported or self-directed intervention. The supported group will have a customised program with a health coach, exercise physiologist and dietitian and can access online information about reversing/slowing frailty, whereas the self-directed group will solely have access to online information.

The FITTEST study will commence recruitment in January 2024, and will recruit 390 participants with mild frailty from geriatric medicine clinics across Australia. We need geriatricians to identify people who they have seen in clinic that may be eligible to participate.
