	Prenatal Exposure Only (n = 10,690)	Postnatal Exposure Only (n = 8,213)	Both Prenatal and Postnatal Exposure (n = 9,781)

Child gets migraines
OR^a (95% CI)	1.33 (1.05–1.68)	1.33 (1.03–1.72)	1.51 (1.20–1.91)
OR^a,^b (95% CI)	1.20 (0.93–1.54)	1.21 (0.92–1.60)	1.30 (1.01–1.68)

Child has headache-related symptoms
OR^a (95% CI)	1.19 (1.12–1.26)	1.36 (1.28–1.45)	1.51 (1.42–1.60)
OR^a,^b (95% CI)	1.16 (1.08–1.23)	1.28 (1.19–1.37)	1.32 (1.23–1.40)

Reference category is no exposure to cell phones.

Adjusted for child’s sex, mother diagnosed with migraines, mother’s feelings of worry, burden, and stress during pregnancy, mother’s age, social-occupational status, and child’s exposure to environmental tobacco smoke in the home.
