  1. Model 1: Number (count) of adversities as a continuous predictor with statistical adjustment for age, ethnicity, and BMI (i.e. ORs in model 1 are adjusted for all variables in the first column).
  2. Model 2: Main effects of the five childhood adversities with the strongest associations with early menarche with statistical adjustment for age, ethnicity, and BMI (i.e. ORs in model 2 are adjusted for all variables in the second column).
