<h4>Background</h4>Current epigenetic studies on aging are dominated by the cross-sectional design that correlates subjects' ages or age groups with their measured epigenetic profiles. Such studies have been more aimed at age prediction or building up the epigenetic clock of age rather than focusing on the dynamic patterns in epigenetic changes during the aging process.<h4>Methods</h4>We performed an epigenome-wide association study of intra-individual longitudinal changes in DNA methylation at  ...[more]
