Stratum-specific effect estimates for maternal diabetes and hypertensive disorders for three strata of maternal pre-pregnancy BMI in SEED

Model / Strata	ASD vs. POP aOR (95% CI)	p-value for interaction	DD vs. POP aOR (95% CI)	p-value for interaction
*Maternal Diabetes*
BMI: low, normal (<25 kg/m²)^a	0.95 [0.71, 1.27]	Reference	1.23 [0.97, 1.57]	Reference
BMI: overweight (25-<30 kg/m²)^a	0.99 [0.71, 1.37]	0.874	0.94 [0.69, 1.28]	0.1833
BMI: obese (≥30 kg/m²)^a	1.10 [0.80, 1.52]	0.523	1.08 [0.79, 1.57]	0.522
*Maternal Hypertensive Disorders*
BMI: low, normal (<25 kg/m²) ^b	1.33 [1.06, 1.67]	Reference	1.36 [1.10, 1.68]	Reference
BMI: overweight (25-<30 kg/m²)^b	1.23 [0.93, 1.64]	0.687	1.31 [1.00, 1.72]	0.840
BMI: obese (≥30 kg/m²)^b	1.17 [0.89, 1.53]	0.479	1.12 [0.86, 1.46]	0.263

Adjusted for maternal age, race/ethnicity, maternal education, maternal smoking, and study site.

^b.

Adjusted for above (a.) plus plurality and parity.
