Associations Between Blood Pressure and Accelerated DNA Methylation Aging.

ABSTRACT: Background Individuals of the same chronological age may exhibit diverse susceptibilities to death. However, few studies have investigated the associations between blood pressure and the accelerated aging. Methods and Results A cross-sectional study was conducted in 288 adults aged ≥50 years. We assessed the DNA methylation-based measures of biological age using CpG sites on the Illumina HumanMethylationEPIC BeadChip. Epigenetic age acceleration metrics were derived by regressing residuals (ΔAge) and ratios (aging rate) of DNA methylation age on chronological age. Dose-response relationships between blood pressure and epigenetic age acceleration were quantified using multiple linear regression and restricted cubic regression models. We found that each 10-mm Hg increase in systolic blood pr
