SMILE: Tracking muscle loss, metabolic health, and aging over time

Sarcopenia, Metabolic Diseases, and Integrated Aging Longitudinal Evaluation (SMILE)

Observational RenJi Hospital · NCT07205510

This project will follow adults to see if combining clinical data, imaging, and blood/tissue samples can detect and track muscle loss and metabolic changes linked to aging.

What this trial studies

SMILE is an ambispective cohort that combines retrospective records with prospective follow-up to map the pathological axis linking sarcopenia, metabolic disorders, and aging. The platform collects multimodal data including demographics, lifestyle factors, clinical phenotypes, laboratory tests, medical imaging, and biospecimens. Researchers will use these data to identify early signs of muscle aging, patterns connecting metabolic disease and sarcopenia, and predictors of adverse outcomes such as disability and mortality. The work is based at RenJi Hospital, Shanghai Jiaotong University, with adults aged 18 and over eligible to participate.

Who should consider this trial

Good fit: Adults aged 18 or older who can give informed consent and participate in clinic visits and assessments are the intended participants.

Not a fit: People who cannot consent, are unconscious, have severe mental illness preventing communication, or have conditions that would confound assessments are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the platform could enable earlier detection of muscle and metabolic decline and guide interventions to reduce falls, disability, and premature death.

How similar studies have performed: Prior cohort studies have linked sarcopenia with metabolic and cardiovascular risk, but large ambispective, multimodal platforms like SMILE are relatively novel.
