Cohort Study Desing in Biomarkers of Aging

Caption

Different approaches to cohort study design in the context of biomarkers of aging. Biomarkers of aging are commonly validated using cross-sectional or longitudinal study designs. Cross-sectional studies involve measurement of biomarkers and chronological age or aging-related outcome data at a single time point. These data can only support association of these measures at that time point. Longitudinal designs, on the other hand, allow for assessment of predictive validity of biomarkers measured at one time point and future aging-related outcomes.
