In the menopause study, Horvath and first author Morgan Levine tracked methylation, a chemical biomarker linked to aging, to analyze DNA samples from more than 3,100 women enrolled in four large studies, including the Women's Health Initiative (WHI) a major 15-year research program that addressed the most common causes of death, disability and poor quality of life in postmenopausal women.
They measured the biological age of cells from blood, saliva and inside the cheek, to explore the relationship between each woman's chronological age and her body's biological age.
