About

This study aims to establish an ambispective cohort platform centered on the pathological axis of "sarcopenia-metabolic disorders-aging progression", integrating multimodal data including demographic characteristics, lifestyle factors, clinical phenotypes, laboratory tests, medical imaging, and biospecimens. Namely 'Sarcopenia, Metabolic Diseases, and Integrated Aging Longitudinal Evaluation (SMILE)'.

Full description

Sarcopenia is an age-related syndrome characterized by progressive decline in skeletal muscle mass, strength, and function. Traditionally regarded as a consequence of aging, it not only impairs physical mobility, nutritional status, and activities of daily living but also significantly increases the risk of falls, frailty, disability, and subsequent hospitalization. Furthermore, sarcopenia is associated with prolonged hospital stays, elevated postoperative complications, and even premature mortality, imposing substantial economic and healthcare burdens on patients, families, and society.

Recent studies have revealed a complex interplay between sarcopenia and metabolic disorders (e.g., diabetes, dyslipidemia, and obesity), which collectively accelerate the aging process and elevate the risks of cardiovascular events, cardiovascular mortality, and all-cause mortality. Therefore, early identification of changes in muscle mass and function, along with preventive measures against sarcopenia, is crucial for mitigating long-term disease risks. However, strategies for early detection of muscle aging progression and at-risk populations remain to be further elucidated.

This study aims to establish an ambispective cohort platform centered on the pathological axis of "sarcopenia-metabolic disorders-aging progression", integrating multimodal data including demographic characteristics, lifestyle factors, clinical phenotypes, laboratory tests, medical imaging, and biospecimens. Namely 'Sarcopenia, Metabolic Diseases, and Integrated Aging Longitudinal Evaluation (SMILE)'. By combining retrospective and prospective cohort analyses, we will longitudinally track individual health data and conduct in-depth exploration of interaction mechanisms. The objectives are to unravel the dynamic interplay between sarcopenia and metabolic diseases in aging. Assess their mid-to-long-term impact on cardiovascular events and all-cause mortality, and develop novel strategies for early identification and risk stratification.

The findings will provide a robust theoretical foundation and key technological support for precision interventions in sarcopenia, delaying functional decline, and optimizing health management in aging populations. This study holds significant implications for addressing chronic disease risks exacerbated by population aging and alleviating associated socioeconomic burdens.
