OBJECTIVE: To investigate whether @entity1277 are associated with lower size at birth, symmetric growth restriction, and @entity600 ; and whether pregnancy smoking explains the association between @entity1278 and fetal growth. DESIGN: Longitudinal population-based cohort study. SETTING: Denmark. SAMPLE: @entity1 from the Danish National Birth Cohort (n = 83 826). METHODS: @entity1 with @entity1278 (n = 1609), @entity1279 (n = 1693) and both ( @entity448 + @entity1279 , n = 634) were compared with unexposed @entity1 (n = 76 724) ( @entity1 with exposure data and singletons n = 80 660) using crude and adjusted linear and logistic regression models. MAIN OUTCOME MEASURES: Size at birth (birthweight, length, head and abdominal circumference and placental weight); gestational age; small- and large-for-gestational-age (SGA, LGA); ponderal index, abdominal/head circumference. RESULTS: Lifetime @entity1278 were prospectively associated with restricted fetal growth and higher odds of SGA [respectively, OR = 1.6 [95% CI 1.3-1.8] and OR = 1.5 [95% CI 1.2-1.9)] compared with unexposed @entity1 . @entity1278 was associated with lower birthweight, length, head and abdominal circumference, ponderal index, higher odds of SGA [OR = 2.90 (95% 1.98-4.26)] and @entity600 [OR = 1.77 (95% CI 1.00-3.12)] compared with unexposed @entity1 . Pregnancy smoking only partly explained the association between @entity1278 and adverse fetal outcomes. CONCLUSIONS: @entity1278 (both active and past) is associated with lower size at birth and symmetric growth restriction, with evidence of worse outcomes in @entity1 with @entity146 . @entity1 with @entity1278 should be advised about achieving full recovery before conceiving. Similarly, targeting smoking in pregnancy might improve fetal outcomes. TWEETABLE ABSTRACT: @entity1278 predicts small size at birth, small-for-gestational-age and symmetric growth restriction.
