What this trial studies

This observational study aims to explore the relationships between obesity, circadian rhythm, and aging by establishing a prospective cohort registry. It will follow 2000 adult participants, including those with morbid obesity and normal weight, over a period of 10 years with annual assessments. Data collected will include clinical information, biological samples, and questionnaires related to sleep quality and circadian activities. The study seeks to understand the pathophysiological and molecular connections between these factors and their impact on aging and cardiovascular health.

Who should consider this trial

Good fit: Ideal candidates include adults aged 20 years and older with a body mass index of 24 kg/m2 or higher, as well as normal weight individuals with a BMI below 24.

Not a fit: Patients with severe systemic diseases or organ failure, or those who cannot provide informed consent, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to improved management and treatment strategies for obesity and related conditions.

How similar studies have performed: Other studies have shown success in exploring the links between obesity and circadian rhythms, but this specific registry approach is relatively novel.
