In multivariate linear regression analyses adjusted for a range of participant characteristics including antidepressant use, depression at baseline, as well as chronic late-life depression over the 12-year follow-up, were associated with overall higher BDNF methylation levels, with two sites showing significant associations (promoter I, Δ mean=0.4%, P=0.0002; promoter IV, Δ mean=5.4%, P=0.021). This evidence concerns the gene BDNF and depressive disorder.
