The Comparability and Reproducibility of Telomere Length Measurements
This research is being done to improve our understanding of methods to measure in telomere length (TL) and how different tissues contribute to variation in determined telomere length. A telomere is a piece of DNA at the end of each chromosome, which protects the rest of the DNA from being damaged. Knowing the length of the telomeres gives us important information about your cellular age, which can be different from your actual age depending on your exposure to certain risk factors. Studies have associated shorter telomere length with a range of risk factors that predict health problems and shortened life expectancy. However, these studies have been done using different methods and different types of tissues from the body. The differences between these studies make it difficult to compare results or help people understand how to live a healthier life. Participants will be asked to complete questionnaires and provide blood, saliva, and cheek cell samples.
