Dynamic molecular choreography of circadian rhythm disorders (DMCRD): a prospective cohort study protocol

BACKGROUND: Circadian rhythm disorders (CRDs) are closely associated with the occurrence and development of various diseases, such as inflammatory and cardiovascular diseases, as well as tumors. The impact of a CRD on bodily health is a complex and comprehensive process, and its molecular mechanisms and signaling pathways are still unclear. We therefore aimed to investigate the molecular mechanism variation and adverse outcomes associated with CRDs in a prospective cohort of CRD cases and controls at term using multiomics data. The study has been tasked with developing a precise health promotion model for the prevention and management of CRDs. METHODS: This will be a 5-year prospective cohort study centered on the health management of individuals with CRDs. One hundred volunteers were recruited and had undergone baseline specimen collection, health examination, and health assessment. All of them will be followed up every year using the same protocol, and their biological specimens will be subjected to multiomics analysis after standardized processing. DISCUSSION: Longitudinal health examination, health assessment, and multiomics data will be analyzed to study the impact of CRDs on the volunteers’ health status. The results of this study will promote the development of targeted health management programs based on precision medicine. TRIAL REGISTRATION: The clinical study registration has been completed (Trial Registration No. ChiCTR2100047242).
