Lifestyle program keeps frail older adults mobile longer
Growing old with multiple diseases at once is the norm, not the exception. A large European trial tested whether an intensive lifestyle program could help frail older adults stay independent. The answer depends strongly on which diseases a person has.
The SPRINTT trial (published in Nature Aging) followed frail older adults and offered them an intensive program combining physical exercise, nutritional support, and coaching, all aimed at preserving mobility. Researchers then analyzed which combinations of diseases (a pattern called multimorbidity, meaning the simultaneous presence of multiple chronic conditions) influenced how well participants responded to the intervention.
The study found that participants with psychiatric conditions and non-specific disease patterns experienced the most consistent clinical benefit. For other disease combinations, the effect was less clear. This suggests that a standard lifestyle intervention does not work equally well for all frail older adults. Who benefits depends on the disease burden a person carries.
Not all frail older adults respond the same way
The finding has implications for how elderly care is organized. Until now, lifestyle programs have been broadly offered to everyone classified as frail. This study indicates that a person’s disease profile matters for who actually benefits, making a case for more personalized approaches.
Exercise remains one of the best-supported interventions for preserving mobility in older adults. But matching the right people to the right intervention is at least as important. This study takes a step in that direction.
What the study does not answer
The research is observational in nature: it shows which patient groups benefited most, but does not explain why. Whether adapting the program to specific disease combinations would produce better outcomes has not been tested. The researchers suggest that future work should focus on personalized lifestyle interventions for frail older adults with specific multimorbidity patterns.
