	≥ 20 years		18–19 years (Teenagers)		PR (95% CI) for mothers’ age within strata of partners’ education
	N with/without outcome	PR (95% CI)	N with/without outcome	PR (95% CI)
Partner has less than secondary education	153/132	1.00 (Reference)	31/54	0.71 (0.53,0.97); p = 0.030	0.71 (0.53,0.97); p = 0.030
Partner has secondary or higher education	83/38	1.22 (1.01,1.48); p = 0.037	13/12	1.02 (0.7,1.51); p = 0.902	0.84 (0.56,1.24); p = 0.376

Measure of effect modification on additive scale: RERI (95% CI) = 0.09 (−0.37,0.60); p = 0.742
Measure of effect modification on multiplicative scale: ratio of PRs (95% CI) = 1.17 (0.72,1.91); p = 0.537
Model IV: PRs are adjusted for planned pregnancy, marital status, place of residence, employment, health insurance, household size, parity, mothers’ education, and COVID-19 pandemic
