Conclusion
The 6-month educational program improved physical function, sleep patterns, and nutritional status compared to the usual healthcare attendance in community-dwelling older adults with frailty or pre-frailty, regardless of their sex, age, frailty status, and educational background. The educational intervention of the FRAGSALUD study, consisting of 4 grouped sessions with 6 follow-up calls over 6 months, not only proved to be effective but also minimized associated challenges, making it easily implementable within care routines. The simplicity and affordability of the FRAGSALUD intervention make it a feasible option for addressing frailty in older adults living in the community, potentially contributing to healthy ageing. Further studies with a longer follow-up are encouraged.
