Environmental exposure to polybrominated biphenyl (PBB) associates with an increased rate of biological aging

Figure 3. Age acceleration positively associates with PBB exposure. The regression coefficient and 95% confidence interval (y-axis) for PBB and each the age acceleration measures, controlling for sex, total lipid levels, and estimated cell types. PBB was positively associated with intrinsic age acceleration (t = 2.07, p = 0.03), extrinsic age acceleration (t = 2.86, p = 0.004), and phenotypic age acceleration (t = 2.43, p = 0.01).
