^aAny adverse perinatal outcome: pregnancy loss, stillbirth, preterm birth, small for gestational age, or neonatal death; among those enrolled <20 weeks and with birthweight data (for live births)

^bAny adverse perinatal outcome: pregnancy loss, stillbirth, preterm birth, or neonatal death; among all eligible pregnancies

HR: Hazard ratios are from Cox Regression Models, clustered by facility used for outcomes of: pregnancy loss, stillbirth, late stillbirth, preterm birth, neonatal death, any adverse perinatal outcome

For instances with case counts ≤5 in an exposure group, we did not perform regression analyses

CESD-10 score was re-scaled to reflect a 10-unit change in score
