Project description:Since their introduction, epigenetic clocks have been extensively used in aging and human disease research. In this study, we reveal an intriguing pattern: epigenetic age predictions display a 24-hour periodicity. These paradoxical age oscillations can be attributed to variations in blood cell type composition and epigenomes, both of which demonstrate circadian rhythmicity. This discovery emphasizes the significance of factoring-in the time of day to obtain accurate estimates of epigenetic age.

Project description:Interventions: Group 1: Circular of the respective health insurance companies at their 50-54 years old insured persons. Besides the information about the offer of screening colonoscopy from the age of 50 and the invitation to its awareness, the letter contains a one-minute risk self-check for colorectal cancer (intervention group).
Group 2: Circular of the respective health insurance companies at their 50-54 years insured persons. The letter includes information about the offer of screening colonoscopy from the age of 50 and invitation to its awareness. The letter does not contain a one-minute risk self-check for colorectal cancer (control group).
Primary outcome(s): Increase of colorectal neoplasm detection rates through an invitation letter containing a risk self-check compared to an invitation letter without risk self-check.
Study Design: Allocation: Randomized controlled study; Masking: Blinded (masking used); Control: Other; Assignment: other; Study design purpose: prevention
