Sex differences delta age. In young adulthood, delta age was higher in men than women (t₍₈₇₎ = −2.24, p = 0.03; Cohen’s d = 0.48; 2A) and this effect survived also the correction for BMI, smoking and alcohol use in the past 30 days. The delta age was also higher in the male vs. female adolescents (t₍₁₂₇₎ = −2.27, p = 0.034, Cohen’s d = 0.40; 2B) and this effect also survived the correction for all covariates (BMI, puberty stage, smoking and prenatal exposure to maternal cigarette smoking (beta = 0.21, p = 0.03, AdjR² = 0.06).
