Associations between early-life factors and anti-Müllerian hormone levels at age 32: multivariable linear regressions^a

Early-life factors	β	95% CI	P value
Birth weight (kg)	0.180	0.06, 0.30	0.003
Maternal pre-pregnancy BMI (kg/m2)	− 0.003	− 0.02, 0.01	0.73
Gestational weight gain (kg)	− 0.010	− 0.02, 0.00	0.16
Maternal smoking (yes/no)	0.085	− 0.07, 0.24	0.27
Paternal smoking (yes/no)	0.002	− 0.11, 0.11	0.97

^aAll exposures were introduced together into the model, adjusted for gestational week, batch, ethnicity, parental education, socioeconomic position at birth, maternal and paternal age at delivery, maternal medical conditions, and participant’s BMI at age 32
