NCT07738393

Brief Summary

The goal of this clinical trial is to determine whether a 6-month healthy-aging education program delivered in person, online, or in a hybrid format reduces frailty and is cost-effective compared with usual care in community-dwelling adults aged 65 years or older with pre-frailty or frailty. The main questions are:

  • Do the three educational programs, considered together, reduce the prespecified 40-item Frailty Index (40-FI) at 6 months more than usual care?
  • Are effects maintained 6 months after the programs end?
  • How do the in-person, online, and hybrid educational programs differ in multidomain frailty outcomes, implementation, costs, and quality-adjusted life-years?
  • Are changes in prespecified blood biomarkers and gut microbiota associated with changes in frailty and related outcomes? The study will enroll 276 participants. Randomization will occur at household level so that enrolled cohabitants receive the same assignment. Households will be allocated to in-person education, online education, hybrid education, or usual care. All three educational programs address physical activity, nutrition, cognitive and emotional well-being, and social connection. Assessments will occur at baseline, 6 months, and 12 months; blood and stool samples will be collected at baseline and 6 months. The trial will compare the average effect of the three active programs with usual care and will estimate modality-specific clinical and economic outcomes.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in the Prespecified 40-Item Frailty Index Score at 6 Months

    A prespecified 40-item deficit-accumulation Frailty Index (40-FI) will be calculated as the sum of observed deficit scores divided by the number of evaluable deficits. The 40-FI ranges from 0 to 1, with higher values indicating greater frailty. A score will be calculated when at least 32 of the 40 deficits (80%) are evaluable. Change will be calculated as the 6-month score minus the baseline score; negative values indicate improvement. The fixed item list, item-level coding rules, permitted intermediate values, denominator, and missing-data rules are defined in the version-controlled 40-FI Specification included as an annex to Protocol and SAP and finalized before enrolment of the first participant.

Study Arms (4)

In-person education

EXPERIMENTAL

Participants allocated to this arm will receive the in-person healthy aging educational program over 6 months. The program will include four face-to-face group sessions of approximately 1 hour each, delivered weekly during the first month. The sessions will address frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. During the subsequent 5 months, participants will receive six telephone follow-up calls to reinforce the educational content and support adherence to the program.

Behavioral: In-person healthy aging education program

Hybrid education

EXPERIMENTAL

Participants allocated to this arm will receive the hybrid healthy aging educational program over 6 months. The program will include four face-to-face group sessions of approximately 1 hour each, delivered weekly during the first month. The sessions will address frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. Participants will also receive an additional familiarization session to support access to and use of the online educational platform. During the subsequent 5 months, follow-up and reinforcement activities will be delivered through the online platform.

Behavioral: Hybrid healthy aging education program

Online education

EXPERIMENTAL

Participants allocated to this arm will receive the online healthy aging educational program over 6 months. Participants will first receive an in-person familiarization and setup session of approximately 1 hour to support access to and use of the online educational platform. The educational content will address frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. Educational content and follow-up activities will then be delivered through the platform during the 6-month intervention period.

Behavioral: Online healthy aging education program

Usual care

NO INTERVENTION

Participants allocated to this arm will continue their usual healthcare and health routines and will not receive the FRAGSALUD-ON educational program during the 12-month follow-up. After completing the 12-month assessment, participants in this group will be offered access to the online educational platform, in accordance with the ethics-approved protocol.

Interventions

A 6-month healthy aging educational program delivered face to face. The program includes four weekly group sessions of approximately 1 hour during the first month, followed by six telephone follow-up calls during the subsequent 5 months. Educational content addresses frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. Educational materials were developed before participant recruitment with artificial-intelligence assistance and were reviewed, edited, and approved by the research team before use. Telephone follow-up is used to reinforce the educational content, address participant questions, and support adherence to healthy lifestyle recommendations.

In-person education

A 6-month healthy aging educational program combining face-to-face sessions and online follow-up. The program includes four weekly group sessions of approximately 1 hour during the first month. Educational content addresses frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. Participants also receive a familiarization session to support access to and use of the online educational platform. During the subsequent 5 months, reinforcement and follow-up activities are delivered through the platform. Educational materials were developed before participant recruitment with artificial-intelligence assistance and were reviewed, edited, and approved by the research team before use.

Hybrid education

A 6-month healthy aging educational program delivered through an online educational platform. Participants first receive an in-person familiarization and setup session of approximately 1 hour to support access to and use of the platform. Educational content addresses frailty awareness, physical activity, nutrition, cognitive and emotional well-being, and social health. During the intervention period, educational content and follow-up activities are delivered through the platform. Educational materials were developed before participant recruitment with artificial-intelligence assistance and were reviewed, edited, and approved by the research team before use.

Masking Details
Participants and intervention providers cannot be masked because of the nature of the educational interventions. A designated investigator with no role in sequence generation, allocation release, recruitment, baseline assessment, intervention delivery, adherence monitoring, or access to unblinded operational data will remain unaware of group allocation and will oversee blinded outcome adjudication and prespecified analytic decisions. Primary and secondary outcome assessments will be performed by trained assessors who are independent of intervention delivery and unaware of group allocation. Participants will be reminded not to disclose their assigned group during assessment visits. Any accidental unmasking of an outcome assessor will be documented. Laboratory personnel and statisticians will work with coded group labels until the analysis dataset, derivation rules, and primary model have been finalized.
Purpose
TREATMENT
Intervention Model
PARALLEL
Model Details: This is a four-arm, parallel-group, household-clustered randomized controlled trial. The household is the unit of randomization: a participant living without another enrolled cohabitant constitutes a cluster of one, and all enrolled cohabitants are assigned to the same study group to minimize within-household contamination. Households will be allocated in a 1:1:1:1 ratio to usual care, in-person education, hybrid education, or online education. Randomization will be stratified by household-level baseline frailty status, defined as all enrolled household members being prefrail versus at least one enrolled household member being frail. Within each stratum, allocation will use a computer-generated sequence with randomly varying, undisclosed permuted block sizes. The sequence will be prepared by an independent statistician who has no role in recruitment, intervention delivery, or outcome assessment.
