Women reporting that their family was poor during childhood had higher frequencies of early menarche than those who reported their family was middle income or well off. As expected from previous literature,1 women who reported they had been heavier or taller than their peers at 10 years of age had the greatest proportion with early menarche and the lowest proportion with late menarche. These associations for weight and height remained after adjusting for each other and for covariates from the main analyses (e.g., menarche ≤10 years: rRR = 2.18 [95% CI = 1.96-2.41] for having been heavier and rRR = 2.05 [1.85-2.27] for having been taller relative to having been similar to peers).
